SEQUESTON  RO 4000

GENERAL DESCRIPTION
SEQUESTON RO 4000 is a highly effective antiscalant and dispersant. It is mainly used for reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) system. It can be used for feedwaters with high level of aluminium and iron oxides. Moreover, it is effectively in controlling of scale formation e.g. calcium carbonate, calcium sulphate, barium sulphate and other inorganic salts.

Product Benefits:

• Compatible uses together with organic flocculants.
• Suitable for drinking water system.
• Have been used for almost all reverse osmosis (RO) membranes.
• Effectively in controlling of scale formation on the membrane surface and reduce

blockage particles.

• It can be used directly or after dilution.
• Effective in pH 5-9.
• Good resistance to aluminium and iron oxides.
• Improve water quality and reduce the operating costs for filtration system.
