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: Pure Aqua manufactured and supplied an industrial ultrafiltration system for the Northern part of the State of California to treat reclaimed water for lumber manufacturing. Our UF systems assist the lumber industry in attaining larger amounts of clean water to create and distribute the wood resources that people use everyday.

Applied Solution: Pure Aqua provides ultrafiltration systems to lumber manufacturers with the goal of ensuring our systems will purify and supply clean water (effluent) to be used during the manufacturing process once returned to nearby rivers. The ultrafiltration system is used as a pretreatment for RO and DI systems. The customer selected the UF to treat the reclaimed water to save the high cost of city water. It is projected that the customer will recover the cost of the equipment in less than 18 months.
