1) Raw water pump

The raw water pump provides a pressurization guarantee for the sand, carbon, and fine reverse osmosis pure water equipment filter. 

Ensure that the inlet water pressure is stable and sufficient, and play a role in pressurization. The pressurized water pressure is greater than the permeation resistance of the mechanical filter, carbon filter and fine filter. It can efficiently pass through the pretreatment system and provide a sufficient water source for the RO system.

2) Mechanical filter



The mechanical filter with multiple filter layers, also known as a quartz sand filter. Which is mainly used to remove the manganese, iron, heavy metals, silt, rust, colloidal matter, suspended matter and other substances with particles above 20um contained in the raw water. The quartz filter can perform backwashing and forward washing operations.


To ensure the water treatment system’s water output and prolong the service life of the water treatment.

A mechanical filter is generally used in the pretreatment process of water treatment projects, mainly to remove mechanical impurities, colloids, Baidu microorganisms, organic matter and active chlorine. 


Mechanical filter cartridge shell materials generally include PE, steel-lined rubber, steel sprayed plastic, steel epoxy anti-corrosion, stainless steel and glass fibre reinforced plastic. 

The mechanical filter media generally include quartz sand, activated carbon, manganese sand, anthracite, etc. 

According to the water inlet mode, it can be divided into the single-flow filter and double-flow filter. It can be used in combination or alone according to the actual situation.

The single-flow mechanical filter has simple piping and smooth operation. 

The filtration flow rate is generally 4-50m/h, and the operation period is 8 hours. 

The double-flow mechanical filter has water inlet devices at the upper and lower ends and a water outlet device at the middle. 



Mechanical filtration is widely used in water treatment of bottled water production. Mainly used for water treatment and turbidity removal, reverse osmosis, and the pre-pretreatment of ion exchange softening and desalination systems. It can also be used for surface water and groundwater removal. 

The turbidity of the inlet water is required to be less than 20 degrees, and the turbidity of the effluent water can reach below 3 degrees. 

The double-layer filter material is the upper layer of anthracite 400mm/1.2~2.5mm; the lower layer of quartz sand 800mm/0.5~1.2mm.

3) Activated carbon filters

Activated carbon filters


The activated carbon filter is a more commonly used water treatment filter. The residual chlorine that can’t be removed in the pre-filter can be absorbed by the pretreatment of the desalination system, which will help ensure the equipment’s service life.

Improve the quality of the wastewater, and minimize pollution, particularly by using a post-stage reverse osmosis membrane, ion exchange resin, and other free residual chlorine poisoning.

At the same time, it captures pollutants like organic molecules that have escaped from the preceding stage. It has a significant adsorption and removal effect on peculiar smells, colloids, pigments, and heavy metal ions in the water. 

It also has the effect of reducing COD. 

The SDI value of RO influent can be further reduced, ensuring SDI<5 and TOC<2.0ppm.

Working principle

The adsorption principle of the activated carbon filter is to form a layer of balanced surface concentration on the surface of its particles. The size of activated carbon particles also affects the adsorption capacity. 

Generally speaking, the smaller the activated carbon particles, the larger the filtration area. 


Therefore, powdered activated carbon has a large total area and a good adsorption effect. 

However, powdered activated carbon can easily seep into the water tank with water, which is difficult to manage and is rarely utilized.

In contrast, granular activated carbon is difficult to flow owing to particle formation and contaminants such as organic matter in the water are hard to block in the activated carbon filter layer.

Its adsorption capacity is strong, convenient to carry and replace.

The activated carbon filter’s adsorption capacity is directly proportional to the duration of time spent in contact with water. The higher the filtered water quality, the longer the contact time required.

Activated carbon filters


The filtered water should slowly escape from the filter layer. Before using, the new activated carbon should be cleaned; otherwise, black water will flow out.

Before the activated carbon is put into the filter, a sponge of 2 to 3 cm thick should be added on the bottom and top to prevent the penetration of large particles such as algae. 


After the activated carbon is used for 2 to 3 months, it should be replaced if the filtering effect decreases. New activated carbon and sponge layer should also be replaced regularly.


To ensure the quality of the water generated by water treatment equipment and to extend the equipment’s service life.

4) Water softener system


Working principle

The automatic water softener system adopts the principle of ion exchange to remove calcium, magnesium and other scaled ions in the water.

When the raw water passes through the resin layer in the exchanger, calcium and magnesium ions are replaced with sodium ions, while the sodium ions enter the water. As a result, the water that exits the exchanger is softened without being harmed.

Because calcium and magnesium are the primary components that form scale, cation exchange resins are generally utilized to replace calcium and magnesium in the water (the most significant components that create scale).

With the rise of Ca2+ and Mg2+, however, resin polishing efficiency decreases.

water softener

The exchange process

The exchange process of sodium resin represented by RNa is as follows:

2RNa + Ca2+ = R2Ca + 2Na+

2RNa + Mg2+ = R2Mg + 2Na+

After the water passes through the sodium ion exchanger, the Ca+ and Mg+ are replaced with Na+.


When enough calcium and magnesium ions have been absorbed by the resin, it must be regenerated. The regeneration process involves washing the resin layer with saltwater in the saltbox to remove hardness ions from the resin and ejecting the resin from the tank with regeneration waste liquid. Thus the soft exchange function has been restored.


The operating procedure for the control valve is as follows: running, backwashing, salt absorption, slow washing, salt tank water replenishment, and forward washing.


Each softening system includes: softening tank, controller (or jet/salt pump), salt tank and salt valve.


Prevent the scale of reverse osmosis and prolong the service life of the reverse osmosis membrane.

5) Precision filters

precision filter


Precision filters (also called security filters). 

The cartridge shell of the precision filters is generally made of stainless steel. The interior uses PP meltblown, wire-fired, folded, titanium filter, activated carbon filter and other tubular filter elements as filter elements. 

Choose different filter elements according to various filter media and design processes to meet effluent water quality requirements.

The filter can also choose a quick-installation type to conveniently replace the filter element and clean. 

The filter element installed in the precision filters device can be divided into 0.5us, 1us, 5us, 10us, and so on. Different filtering precisions are chosen depending on various situations to guarantee the accuracy of the downstream water and membrane elements’ safety.


The precision filters are widely used in pharmaceutical, chemical, food, beverage, water treatment, brewing, petroleum, printing and dyeing, environmental protection and other industries. 

It is ideal for filtration, clarification, and purification of various liquids.

precision filter


The precision filters are mainly composed of the filter housing, filter membrane, etc. 

The filter housing is primarily consisting of R304 stainless steel. If used on special occasions, such as acid and alkali resistance, R316 stainless steel can be used as the housing. 

It can be divided into flange and clamp types, and flange type housing is mainly used on occasions with large filtering flow. 

The filter element, which is positioned in the center of the filter housing, is mostly made of PP filter cotton.

In some situations, a wire-wound filter element or an activated carbon filter element can be utilized. The number of deployed filter elements may range from one to dozens, with the size of the processing capacity being the main factor.

6) Reverse osmosis system


The reverse osmosis system is remarkable for pure water filtration and production, which uses the selective permeation principle of the reverse osmosis membrane. 

By applying specific pressure to the raw water passing through the reverse osmosis membrane with the high-pressure pump, the water molecules in the raw water can penetrate the membrane and dialysis out.

However, other inorganic salts, microorganisms, and organic substances cannot pass through the membrane due to the retention characteristics of the reverse osmosis membrane, so that pure non-ionized water can be obtained.


Reverse osmosis (RO) is an important part of membrane separation technology, even in the flow chart of the bottled water manufacturing process. Under the action of higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus leaving these substances and moisture out.

Because the reverse osmosis membrane pore size is tiny (only about 10A), it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc., in the water (removal rate as high as 97-98%).

It has good water quality, low energy consumption, no pollution, simple process and easy operation. It has become the most energy-saving and straightforward technology for seawater, brackish water desalination, and pure water production.

At present, it has been widely used in many industries such as medicine, electronics, chemical industry, food, seawater desalination and so on.

Reverse osmosis system


The RO system should adopt an automatic control operation mode according to the water level of the first-level desalinated water tank and the production volume of the reverse osmosis system.

Suppose it is necessary to start, stop or switch the system, it shall be manually switched after confirmation by the operator.

The control of the RO system and the control of the entire chemical water treatment equipment are realized through the control system (PLC) in the control room.


According to the raw water quality, ibottling selects imported membrane elements with large water permeability, high desalination rate, good chemical stability, good anti-pollution performance, and good mechanical strength.

iBottling provides the membrane module’s maximum membrane flux, recovery rate, and feed water membrane area for the source water quality and feed water SDI value.

The arrangement and combination of stages and sections of membrane modules are determined by water quality, recovery rate, and water production.

Reverse osmosis system


The reverse osmosis system is currently the most advanced and practical desalination equipment at home and abroad. This system uses the reverse osmosis membrane to remove organic matter, bacteria, and viruses. 

And the membrane can be operated in an ultra-low pressure working environment to achieve energy-saving and reduce equipment investment and operating costs. 

And to achieve the best combination of water permeability and desalination, Dow membrane has been widely used globally, and its technical performance and product quality have won praise from users.

3) Air compressor


The PET air compressor is the main body of the air source device of the blow molder.

It is a device that converts a motor’s mechanical energy into gas pressure energy. And it is a unique air pressure generating device for the bottle blowing machine.


Blowing air compressors are mainly used in the supporting industries of iBottling blow molder.

Blowing air compressors can be divided into low-pressure blow molding machine (15-25bar), medium pressure blow molding machine (25-35bar), high-pressure blow molding machine (35-40bar) according to air pressure.

According to their working principles, blowing air compressors can be divided into piston compressors, screw compressors, and centrifugal compressors.

The principle of operation for a positive displacement compressor is to compress the gas volume in order to boost gas molecule density per unit volume, resulting in higher compressed air pressure.

The working principle of a screw compressor is twin screw compression.

The kinetic energy of the gas in the cavity of the twin-screw compressor is converted into pressure energy, increasing the compressed air pressure.

The centrifugal compressor uses the high-speed rotation of the impeller to convert the gas into kinetic energy under the high-speed centrifugal condition, thereby providing the compressed air pressure.

Choose model

First, select the type of air compressor according to the characteristics of the air compressor.

According to the working pressure and flow parameters, the output pressure PC and the suction flow QC of the air compressor are determined. The air compressor model is finally selected.

The choice of air compressor is mainly based on the pneumatic system’s working pressure and flow rate.

The working pressure of the gas source should be about 20% higher than the highest working pressure in the pneumatic system. 

Because the loss along the way and the local loss of the gas supply pipeline should be considered.

If the working pressure requirement in some parts of the system is low, a pressure reducing valve can supply air.

The rated discharge pressure of the air compressor is divided into 

  • low pressure (0.7~1.0MPa), 
  • medium pressure (1.0~10MPa), 
  • high pressure (10~100MPa) 
  • and ultra-high pressure (above 100MPa), 

Which can be selected according to actual needs.

air compressor

Low-pressure air compressor

The commonly used low-pressure air compressors in the auxiliary equipment of the blow molding machine are mainly piston-type low-pressure air compressors and screw-type low-pressure air compressors.

Use the free gas as a piston to compress the gas and then expel the gas.

The screw compressor is a rotary positive displacement compressor in which two rotors with helical gears mesh to compress and discharge gas.

Compared with the piston-type low-pressure air compressor, the screw-type operation is stable and safe, energy-saving, and automatic and adjustable. All iBottling blow molding machines use low-pressure screw air compressors.

Function: Carry out pre-blowing and low-pressure blowing. Complete the blowing with high pressure to ensure a one-time bottle formation rate.

High-pressure air compressor

It comprises a compressor host (excluding gas storage tank), motor, inter-stage cooler, air separation and purification device, etc.

The gas inhaled in the tank is compressed into three levels and then separated and filtered to purify the high-pressure air without odour.

Function: Compress the air in the free state into a clean and odourless high-pressure gas, blow the preform at high speed, and form a bottle at one time.

5) Blowing machine air dryer

air dryer


The air dryer is a kind of equipment that uses the working principle of cooling and condensation to dry compressed air.

The refrigeration dryer adopts the working principle of cooling and condensation. It is mainly composed of three parts: a heat exchange system, a refrigeration system and an electrical control system.


The compressed air first enters the pre-cooler for air-air or air-water heat exchange, removing part of the heat energy. 

And then enters the cold and hot air exchanger. Exchanges heat with the cold air cooled to the pressure dew point from the evaporator. The temperature of the compressed air is further reduced.

After that, the compressed air enters the evaporator to exchange heat with the refrigerant. The compressed air temperature drops to 0-8°C.

The water in the air will precipitate at this temperature; after being separated by a gas-water separator, it will be discharged through an automatic drain.

The dry low-temperature air enters the cold and hot air exchanger for heat exchange, and is output after the temperature rises.


An optional microcomputer control system, with import and export temperature display, dew point temperature display, pressure display, fault alarm and other functions. And it can realize centralized computer control online.


The refrigeration compressor is selected from the United States TECUMSEH, BRISTOL, France MANEURCP and other world products, with stable operation, low noise, power-saving and long service life.


The pre-cooler adopts newly developed internal and external multi-fin exchange tubes. 

The efficiency is increased by more than 3 times. 

And the power consumption can be saved by more than 60%

The large evaporator design is suitable for various climates to ensure a stable dew point.

The gas-water separator adopts a double separation design to separate and remove the condensed water.

6) Air filter of bottle blowing machine

Air filter


The function of the air filter is to separate the liquid water and liquid oil droplets in the compressed air, and filter out the dust and solid impurities in the air. Still, it cannot remove the gaseous water and oil.


The air generally contains harmful substances such as dust, rust, and moisture.

The compressed air in the first filter device will have a coalescence effect, condensing some particles and staying on the filter.

These tiny particles will become larger water droplets after a long time of condensation.

Compressed air will enter the separation chamber, and its flow rate will naturally slow down.

The particles passing through the previous channel will gather again and condense on the water trap.

The non-condensed water is water with impurities and will flow along the bottom of the device.

As soon as it reaches the location of the drainage equipment, the electric drain gate will discharge the water.

After filtering, you will get dust-free, oil-free, and water-free, relatively dry, clean compressed air.

Clean air can effectively extend the service life of pneumatic equipment.

7) Mold temperature controller


Blow molding machine temperature controller is used in the plastic bottle industry to control the mold temperature.

The control of mold temperature directly affects the appearance of bottles.

The mold is always maintained at a constant temperature to ensure the product bottle mouth is smooth.

Prevent defects such as lack of glue, deformation, bubbles, and imprints, and ensure even thickness of the bottle wall.

Improve production efficiency, improve product quality and appearance and surface finish.

The temperature rises and falls fast, and the temperature control is accurate and stable. 

It is one of the necessary auxiliary equipment in the plastic bottle industry.
