Sub Title: Cleaning 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 portable if desired.

Uses for Membrane Cleaning Skid

The membrane 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 membrane cleaning 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 membrane cleaning skid wiring is completed and tested before shipment.

Membrane Cleaning Chemicals
Acid 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 Process
Reverse 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 using a membrane cleaning skid. The following is a summary of the design of Pure Aqua, Inc. membrane cleaning skids and cleaning chemicals. More detailed instructions are available in the Operating and Maintenance manual for the Pure Aqua, Inc. Cleaning Stations.

Video on Cleaning Skid Yemen

Cleaning Skid was a piece of a water treatment system that also included a high brackish RO system and multimedia filter that was then delivered after completion to a major company in Yemen. The cleaning skid is used to clean the RO membranes while they are in the system. This extends the life span of the membranes and ensures high quality product water...more->
