A membrane is a thin,
film-like structure that separates two fluids. It acts as a selective barrier,
allowing some particles or chemicals to pass through, but not others.
Various types of crystal growth
activities occur on these membranes.RO feed water membranes are known to
accumulate huge quantity of calcium sulfate scale which is very difficult to be
removed.
ALKRO range of RO Antiscalants or Antifoulants are
very effective for the prevention of these inorganic scales.Chemtex
manufactures these RO Antiscalants or Antifoulants which surpasses the
performance of other antiscalants
(such as Perma-treat 191 etc. of Nalco) under stressed conditions of high pH.
ALKRO antiscalants also effectively stabilizes metal ions to prevent fouling of
the membrane.
Dosage:
ALKRO antiscalant or antifoulant chemical is normally fed continuously prior to the final cartridge filter. It should be injected by chemical dosing pump from a dilution tank or directly from the drum to the feed water line. The amount of antiscalant or antifoulant required to inhibit scale formation depends on the quality of feed water and size of the membrane system.
ALKRO R.O. MEMBRANE ANTISCALANTS are available in low and high
pH that enables to adjust the pH of permeate water without adding acid and
alkali.
The major
benefits of these chemicals are
- Scaling is prevented.
- Reduced downtime required for periodic cleaning of membranes
- Enhances the quality of permeate water
- Very easily used & handled.
- Maintains flow rate close to design and saves power.
- Increase in productivity.
