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 fouling even when these are present in high concentrations. Pretreat Plus® – 0100 does not react with other chemicals in the treatment, such as coagulants.

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

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

The advantages of using Pretreat Plus® – 0100

  • Eliminate acid injection
  • Reduces membrane cleaning
  • Extend membrane life
  • 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 incrustations

Dosage recommendations:

Pretreat Plus®-0100 is a working product that can be used in almost any water without the need for water chemistry analysis. For small treatment systems of less than 100 gpm feed, a starting dose of 5 ppm is suggested. Pretreat Plus® -0100 is also an excellent choice for larger systems with good results in pilot tests for stable operation.
