Meliorate Membrane Cleaning Skid

Meliorate Membrane Cleaning SkidCleaning Skid Series The cleaning skid is designed for manual operation through a local control box located on the skid. A chemical storage tank is mounted on its own stand and connected to the skid with either hard PVC piping or quick disconnect fittings and flexible hoses. This gives the unit the ability to be mounted in a permanent location or totally portable if desired. The piping is schedule 80 PVC that is hydrostatically tested at the factory. The electrical enclosure is NEMA 4X. All skid wiring is completed and tested before shipment.Standard FeaturesSkid mounted unitChemical solution tank with coverPVC piping316L Stainless cleaning pump5 micron cartridge filter with stainlessSteel housing (CS8) or polypropylene (CS4)Local flow meterTank level switch (CS 8)220V/1Ph/60Hz or 460V/3Ph/60HzAvailable Options220V/1Ph/50Hz or 380-415V 3Ph 50HzpH ControllerElectric heater for chemical tank withTemperature controllerFlexible hoses for cleaning connectionWheel mounted skids for smaller unitsMixerApplicationsMembrane CleaningDescalingMembrane Cleaning ChemicalsAcid and alkaline cleaning chemicals are most commonly used for membrane cleaning. Acid cleaners are designed to remove inorganic and iron deposits. Acid cleaning should be performed at a pH of about 2. Alkaline cleaners are designed for removal of biological matter, organic foulants, and silica deposits. Alkaline cleaning is performed at a pH of about 12.

Membrane Cleaning ProcessReverse Osmosis membrane elements can experience a decline in performance due to the accumulation of deposits on the membrane surface. Mineral scale, colloidal particles, biological matter, and insoluble organic compounds are the usual causes of membrane fouling. When production of a Reverse Osmosis system drops by at least 10 percent, or the differential pressure increases by 15 percent (over normal operating conditions), membrane cleaning should be performed. The following is a summary of the design of Meliorate Engineers, Inc. cleaning stations and cleaning chemicals. More details instructions are available in the Operating and Maintenance manual for the Meliorate Engineers, Inc. Cleaning Stations.
