Ultrafiltration System for Rain Water Treatment 20 GPM - San Francisco

Product Description

Ultrafiltration is a form of filtration that uses membranes to separate different fluids or ions. Ultrafiltration is not as fine a filtration process as Nanofiltration, but it also does not require the same energy to perform the separation. Ultrafiltration uses membranes that are partially permeable to perform the separation, but the membrane pores are typically much larger than Nanofiltration membrane pores. TOC removal with ultrafiltration can reach up to 60%

Water Challenges: Can rainwater be safely consumable? Definitely. How safe? That depends on the type of filtration and purification used. Water contaminants that are comprised in rainwater include animal excrement, algae, sand, leaves, and other unwanted particles which can be removed through ultrafiltration.



Applied Solution: Pure Aqua manufactures ultrafiltration systems to reduce the suspended solids that lead to water problems. Removing these contaminates improves the efficiency and increases its ability to work at full capacity. Ultrafiltration are used as a pre-treatment for further purification of the feed water with reverse osmosis systems and post-treatment. An Ultrafiltration System completed production in order to be delivered to San Fransisco for the application of rain water treatment.



  • Superior filtration performance with high flux
  • Very small nominal pore diameter (0.03 µm)
  • Efficiently gets rid of bacteria and viruses
  • Periodically back washed and air scoured to enhance overall performance and casting off the fouling layer to extend working life
  • Low fouling membrane modules
  • UF Outside-In or Inside-Out Configuration lets in reduced plugging and greater solids loading
  • Basic, vertical, modular plan approves low cost, compact systems
  • Effective membrane cleaning has a high chemical resistance and temperature tolerance
