Reverse osmosis

The formulations developed by AQUAPROX prevent the build-up of deposits (biological, organic, or mineral deposits) in water treatment membranes, and deterioration of them caused by oxidising agents (chlorine).

To increase the membranes’ service life, AQUAPROX developed a specific range of products to respond to the problems linked to the various types of pollution encountered.

Issues encountered

  • Delivery times too long
  • Storage outsourced to a supplier’s premises
  • Lack of advice and advice about reverse osmosis chains
  • Cumbersome technical/economic solutions

Technical solutions applied

In addition to supplying reagents within short delivery deadlines, we offer advice and follow-up about their implementation and regarding the whole water production chain thanks to our know-how in the field of membrane techniques.
The objective of this consulting approach regarding the implementation of treatments is to optimise injection intervals and dosings.

Implementation of

  • The AQUAPROX MTN 2950 sequestering agent, a reagent derived from our green range, which is a product that does not pose health hazards, that does not have a pictogram, and is environmentally friendly.
  • Déchloration AQUAPROX MTN 9740, a reducing agent containing potassium bisulphite among other things. AQUAPROX MTN 2510, , a reducing agent based on sodium bisulphite. AQUAPROX MTN 6260 and AQUAPROX MTN 6280, acid and alkaline cleaning products providing a response to reverse osmosis unit cleaning needs..AQUAPROX MTN OX, non-oxidising biocide, which enables biofilm development to be combated
    effectively during reverse osmosis units’ shut-down and restart periods
