AQUCAR™ MEM 20 Water Treatment Microbiocide

AQUCAR™ MEM 20 is a Non-Oxidizing Biocide to Reduce Biological Fouling in Reverse Osmosis (RO) Systems for Industrial Water Production and off-line cleaning of RO membranes producing potable and municipal water.

Document Links:

Used In:

  • RO systems in the industrial market and for off-line cleaning of RO membranes producing potable and municipal water


  •  Treats the membranes and kills bacteria that contribute to biofouling
  •  Controls bacteria and reduces biofouling in various membrane system types (reverse osmosis, ultra-filtration, nano-filtration and microfiltration) used for industrial water processing
  •  Functions immediately upon introduction into the feed water and antimicrobial control is achieved rapidly and economically when dosed properly
  •  Hydrolyzes quickly at alkaline pH conditions - becomes deactivated after use
  •  Compatible with thin-film composite (TFC) polyamide RO membranes at use concentration levels
  •  Utilizes a proven formulation of DBNPA (2,2-Dibromo-3-nitrilopropionamide)
