Meliorate Membrane Cleaning

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 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.

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. 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.
