Product categories

Roprep is the antiscalant of the Rochem chemical range. It keeps scale-forming substances such as silica and calcium salts in solution and stops inorganic ions from depositing on the membrane. This raises treatment efficiency, reduces the need for membrane cleaning and extends membrane life.

Key features

  • Prevents silica and calcium scale on the membrane
  • Fewer cleanings and longer membrane life
  • Dosed directly into the feed water
  • For RO, NF, UF and MF systems
