Purified Water System Disinfection & Biofilm Remediation

Care P-WD is a sterilant constituted of food grade hydrogen peroxide and peroxyacids. Its potential to eliminate biofilms even in presence of high organic load makes it the most efficient and effective disinfectant for water and water purification systems. Where chlorine and chlorine dioxide fail to eliminate biofilms and leave behind additional burden of DBPs (Disinfection By-products) and high rates of corrosion, Care P-WD comes in as an effective replacement.

Care P-WD is colorless and odorless. It renders biofouled water odorless. Despite being a strong oxidizer, Care P-WD is highly compatible with all the material of construction of various components in a purified water system at recommended dosages. Approval for the combination of hydrogen peroxide and peroxyacid by USFDA as a secondary direct food additive in food for human consumption (21CFR:173;370) extends the use of this product in food industry. Care P-WD is recommended for:-

01
Contact sanitization of the purified water lines by recirculation at 2% dilution.
02
Contact sanitization of components by dip treatment at 2% dilution.
03
Treatment of raw water by constant dosing at 50ppm to 70ppm depending on the bio-organic load.
04
Contact sanitization of empty tanks by fogging and/or spraying at 2% to 6% dilution depending upon the corrosion and biofilm layer.
Areas of application :-

Care P-WD is well suited for drinking/process water systems.

  • Water Tankers
  • Raw Water
  • Overhead tanks
  • Pipelines
  • Softener
  • Resin filters
  • Resin filters
  • Process water
  • Generation System
  • Distribution Lines
  • Water Containers
  • Bottle Filling Machines
  • Cleaning in Place
Benefits of using Care P-WD :-
  • Safe and compatible with polyamide based RO membranes and piperazine based nanofiltration membranes.
  • Care P-WD controls micro-organisms even at a residual presence of less than 2mg/L. Odor problems are eliminated.
  • Does not produce tastes and odors associated with products.
  • Due to more effective disinfection, increased water recirculation rates are possible.
  • Care P-WD is not corrosive to any metal or alloys.
  • With Care P-WD the cycles of concentrations in the recycle water may be increased, therefore decreasing waste discharges and associated costs.
