Product Overview

VerdePure-CAP is a safe and effective non-oxidizing biocide with advantages such as sustained good bacteriostatic efficacy, high efficiency at low doses, and rapid biodegradation. It is safer to use than formaldehyde, chlorine, or peracetic acid. Adding VerdePure-CAP to the RO feed water quickly controls microorganisms, prevents the development of microbial resistance due to long-term use of a single biocide, and reduces RO operating costs.

Physical and Chemical Properties

• Physical state: Liquid
• Specific gravity: 1.05 ± 0.05
• Appearance: Colorless to pale yellow liquid
• pH value: 2–4
• Freezing point: 0°C
• Solubility: Completely soluble in water

Methods of Use:

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

(1) Continuous Dosing

Inject VerdePure-CAP 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-CAP 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-CAP biocide solution can also be prepared and circulated at low pressure for no less than 60 minutes.
