RoCide™ DB20 is a concentrated, fast-acting, non-oxidizing liquid biocide for intermittent use that provides instant antimicrobial activity. It is based on a 20% solution of the active ingredient dibromo nitrilopropionamide (DBNPA). RoCide DB20 is certified by the U.S. Environmental Protection Agency (EPA) for use in reverse osmosis (RO) systems. It degrades rapidly and naturally, making it a cost-effective method of eliminating contamination in compliance with strict discharge regulations.VIEW ALL CHEMICALSVIEW SUPPORT SERVICES

Selecting the right cleaning chemicals extends system run times between cleanings, reduces chemical costs and extends productive membrane life and overall system up-time.
Provides a cost-effective solution for biological fouling, which is one of the most challenging issues faced by operators of polyamide membrane separation systems.
Inhibits scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec products help extend system run times, reduce cleaning frequency, and increase the productive life of RO elements.
