Specialty Biocide for Reverse Osmosis

VerdePure-ADJ

Product Overview

VerdePure-ADJ is a safe and effective non-oxidizing biocide featuring high efficiency, broad spectrum, easy biodegradability, and no residual toxicity. It is safer to use than formaldehyde,chlorine, or hydrogen peroxide. Adding VerdePure-ADJ to the RO feed water quickly controls microorganisms, while it naturally hydrolyzes to form low-toxicity compounds.

Physical and Chemical Properties:

  • Physical state: Liquid
  • Specific gravity: 1.05 ± 0.05
  • Appearance: Colorless to pale yellow liquid
  • pH value: 3–5
  • Freezing point: 0°C
  • Solubility: Completely soluble in water

Methods of Use:

Biocide VerdePure-ADJ can be applied in the following three ways.

(1) Continuous Dosing

Inject VerdePure-ADJ upstream of the cartridge filter at a dosage of 2–5 ppm.

(2) Intermittent Continuous Dosing

Inject intermittently on a continuous basis, e.g., for a few hours every day, or every other day or week. This reduces operating costs while effectively controlling bacterial growth. Dosage used is 50–100 ppm.

(3) Shock Dosing

Prepare a biocide solution with 5% concentration of VerdePure-ADJ and introduce it into the system using a low-pressure pump.Soak for 60 minutes; extend the soaking time if the system is heavily fouled. Then flush with RO permeate or demineralized water for 15 minutes. For heavily fouled systems, a 10% concentration VerdePure-ADJ biocide solution can also be prepared and circulated at low pressure for no less than 60 minutes.
