Pretreat Plus ® - 0100 is a broad spectrum antiscalant that controls calcium carbonate, silica, iron, and all poorly soluble salts that form scale in reverse osmosis membranes.

Protects membranes from inorganic dirt even when they are present in high concentrations. Pretreat Plus® - 0100 does not react with other treatment chemicals, such as coagulants.

This product has greatly reduced operating costs by eliminating the need to inject acid, and extended period between membrane cleanings.

Due to its effectiveness, Pretreat Plus® - 0100 has also reduced the costs of reverse osmosis (RO) and nanofiltration (NF) membrane replacement, increasing the life of the membrane. Due to the success of Pretrate Plus® - 0100, it continues to displace greater water treatment technologies and competing products.

The Advantages of Using Pretreat Plus® - 0100

  • Eliminate acid injection
  • Reduces cleaning of the membrane
  • Extend the life of the membrane
  • Lower operating costs
  • Certified under the ANSI / NSF 60 standard for the production of drinking water.
  • Compatible with RO, NF and UF membranes regardless of manufacturer.
  • Does not react with other chemicals
  • Controls iron, silica, and mineral scale
