DBNPA-20 is a class of non-oxidizing biocides used to control microbial special biocides in reverse osmosis membrane systems. DBNPA-20 reverse osmosis special fungicide is a fast-acting broad-spectrum fungicide. For reverse osmosis membrane desalination systems that utilize industrial wastewater, seawater, and other surface waters containing microbial sources as a source of water, biocontamination of membrane fouling is a ubiquitous problem. The incompatibility of chlorine gas and other oxidizing biocides commonly used in water treatment with polyamide reverse osmosis limits the use of such bactericides.

The formular biocide is an aqueous solution of CMIT/MIT and DBNPA. It's a classic and economical synergistic bactericidal preservative, broad-spectrum bactericidal and antibacterial (bacteria,yeast,mold), which is specially developed by our company for water-based products. It can quickly sterilize bacteria and have long-term antibacterial effect, and is now widely used in water reducing agent, papermaking and other industries.
