Water Challenges: Cleaning skids are utilized for the cleaning and reuse of ultrafiltration membranes in order to ensure continuous usage. Cleaning is executed at low pressures to reduce permeate production and redeposition of dirt on the membrane element. A small amount of permeate should be produced in order to gain high cross-flow velocities across the membrane surface. High cross-flow velocities are excellent in effectively removing foulant from the membrane surface. In order to remove organic fouling, biofouling and colloidal fouling effectively, cleaning at high temperatures (above 86°F, or 30°C) is important. It isn’t recommended to clean at temperatures below 68°F (20°C) due to the very slow chemical kinetics at low temperatures.

Applied Solution: A UF cleaning system was manufactured and supplied to a major company in WI, USA. This system was designed with the capability to clean 32 ultrafiltration modules. The system came complete with a SS pump, 5 micron cartridge filter, pH controller, electric-heater, and a 1000 gallon HDPE tank. A UF cleaning system consists of a tank, cleaning pump, cartridge filter and a heating/cooling device. The cleaning system is attached to the reverse osmosis system either with flexible hoses or stainless steel or PVC piping. The materials used for the cleaning system should be non-corrosive and have the capability of handling a pH range of 1-13 and temperatures up to 122°F (50°C).
