  Ultrafiltration is a membrane separation process based on the principle of sieving separation and pressure as the driving force, and the filtration accuracy is in the range of 0.005-0.01μm, which can effectively remove particles, colloids, bacteria, heat sources and polymer organic substances in water. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase conversion, operates at room temperature, is particularly suitable for the separation of heat-sensitive substances, and has good temperature resistance, acid and alkali resistance and oxidation resistance, and can be used continuously for a long time under the conditions of 60 °C and pH of 2-11. The ultrafiltration process can be divided into three types: batch operation, continuous ultrafiltration (CUF) and refiltration. Intermittent operation has maximum transmittance and high efficiency, but low throughput. The continuous ultrafiltration process is often carried out under partial circulation, and the circulating volume in the circuit is often much larger than the amount of feed liquid, and is mainly used in large-scale treatment plants. Heavy filtration is often used for the separation of small and large molecules。

Seawater desalination: Reverse Osmosis is the device that uses semi-permeable membrane under the pressure differences function to make the salt water desalination and purification. It is on the contrary of natural direction, so it is called reverse osmosis. It can remove more than 97% solubility of salts in the water and more than 99% of the gel, micro-organisms, and particulate organic matter and so on.It is the first choice equipment of modern water and purified water. RO usually has I and II stages.   Advantages: 1. Auto operating by pressing one key, easy and convenient to operate. 2. Auto sea water flushing and fresh water flushing 3. Touch screen + PLC automatic control+ soft start, more integrated and convenient, real-time running process, more vivid and visualized. 4. Auto dosing, reducing the fouling of the seawater RO membrane. 5. The machine sets up high and low pressure protection to prevent the machine from breakdown. 6. Device fault alarm and indication is convenient for identifying the causes and maintenance quickly. 7. Kinds of flow and pressure testing instruments, monitoring the device operating state at any time 8. Online conductivity meter, monitoring the output water quality at any time. 9. Fully polished stainless steel frame, safe and fastness, elegant appearance. 10. USA imported DOW brand seawater RO membrane, max salt removing rate can reach up to 99.7%. 11. High quality quartz sand filter, can remove the large impurities, alga and so on, and can be manual cleaning independently. 12. All of the high pressure fittings adopt SS316 material, safe and corrosion resistant. 13. Low pressure fittings adopt high quality UVPC material. 14.Customized end side port FRP membrane housing, simple connection, safe and reliable. 15. Dosing pump, accurate dosing, reducing the fouling of the seawater RO membrane Metering pump with the power switch, convenient to start and stop. The power cord and dosing tank’s level signal lines use the navigation plug connection, convenient disassembly of metering pump. 16. High quality SS316L high pressure pump, safe and corrosion resistant, running more stable. 17. Cartridge filter protect RO membrane, prolong RO membrane's service life. 18. High quality stainless steel raw water pump. 3. Final Production water of ultraviolet disinfection online to ensure the output water quality. 19.High quality SS316L electric slowly open valve, slow opening and closing device high pressure. 20. Universal wheel and adjusting legs make the machine move easier and portable, and is suitable for installation and use under more conditions.

The technology of this system includes tubular ultrafiltration membrane, seawater desalination technology, DTRO ultra-high pressure desalination, and so on.

We are collaborating with Foxconn on this project, and for this order, we will provide them with a 200m3 per hour ultrafiltration and reverse osmosis system.
