Customer Case Study: How an Angola Juice Factory Won High-End Clients with Customized Water Treatment Solutions

Background An Angola-based juice factory required high-quality water treatment equipment to produce premium juice syrup. With a processing capacity of 20 tons per hour, the client had demanding requirements for water quality to ensure the best taste and quality of the juice. The raw water supply was from the local municipal water, which had an electrical conductivity of 250us/cm. The client demanded an outlet water quality of less than 10us/cm to meet their high standards for product quality.

Solution After studying the client’s requirements, a customized water treatment process was designed to meet the specific water quality needs of the client’s juice production line. The system comprised multiple stages:

Angola's juice production line requires high-quality water treatment equipment to provide the best water quality.

01.

Multimedia Filtration

During the multimedia filtration stage, our system used a combination of quartz sand, anthracite, and fibers as the primary filter media to effectively remove suspended solids, sludge, and other solids from the water. Through this process, we were able to achieve a solid removal rate of more than 95%, ensuring that the water met the required standards.

02.

Activated Carbon Filtration

To remove impurities such as high molecular organic matter, colloids, odor, residual chlorine, and other contaminants, our system employed activated carbon filtration equipped with granular activated carbon. With a strong adsorption capacity, the filter was able to remove more than 90% of impurities on average, ensuring that the water quality met the required standards. We also ensured that residual chlorine was limited to ≤0.1mg/L, as chlorine is a strong oxidant that can damage the reverse osmosis membrane.

03.

Chemical Dosing System

To prevent scaling of the reverse osmosis membrane, our system used an antiscalant device. We employed a US-based Milton Roy metering pump to ensure accurate dosing and stable equipment operation. The dosing chemicals used included dispersants such as phosphates, chelating agents or complexing agents such as EDTA, and coagulants such as polyacrylamide. Through this system, we were able to achieve a scaling rate of less than 0.1%, ensuring the long-term stability and performance of the reverse osmosis system.

04.

Fine Filtration (Safety Filter)

During the fine filtration stage, we used a stainless steel filter with filtration precision of 10 µm, 5 µm, and 1 µm to reduce or eliminate any particulate matter that may have leaked from the pre-treatment equipment. This process ensured that the water entering the reverse osmosis system met the required standards, and that the performance and life of the reverse osmosis membrane were protected.

05.

Reverse Osmosis System (RO)

Using reverse osmosis membrane technology, our system was able to desalinate the feed water. By applying an external pressure greater than the osmotic pressure to the concentrated solution, the solvent flowed from the concentrated solution through the semi-permeable membrane into the dilute solution, effectively removing suspended solids, organic colloids, and other impurities from the water. Our system was able to achieve a desalination rate of more than 99.5%, ensuring that the final water met the required standards and was suitable for various applications.

  1. Operating Principle: Penetration – When a solution with different concentrations is separated by a semi-permeable membrane for two minutes, the solvent in the diluted solution penetrates through the semi-permeable membrane into the concentrated solution. Reverse osmosis is the scientific method of reversing the natural osmosis process. On the side of the concentrated solution, when external pressure greater than the osmotic pressure is applied, the solvent changes its initial osmosis direction to the reverse and enters the diluted solution through the semi-permeable membrane from the concentrated solution side.

  2. Water Supply Requirements: Turbidity ≤ 2 degrees, Water temperature: 5-35 °C, SDI ≤ 5, Fe ≤ 0.1 mg/L, pH: 4-11, Residual chlorine ≤ 0.1 mg/L.

  3. The main component of the system is the membrane element from the American company Dow. The desalination rate of a single membrane is ≥99%, and the desalination rate of the system is 97-99%. It can effectively remove suspended solids, organic colloids, organic matter, bacteria, viruses, etc. To ensure stable and long-term operation of the reverse osmosis device, a standard automatic flushing device for impurities such as heat sources is installed.

  4. Membrane Material: The commonly used membrane is a fully aromatic composite membrane made of polyamide with a high degree of interconnectivity (abbreviation: polyamide composite membrane).
