Bactericide

Brief Introduction:

Reducing bacteria (SRB) as an water treatment

BG is a quaternary-ammonium-salt cationic surfactant and a multiple quaternary ammonium salt germicide. It has a stronger germicidal ability and certain effect of sludge stripping, and is efficient and low toxic, and will not be influenced by any changes in water hardness and pH, with chemical stability. 

 

BP is a high-molecular polymer germicide. After ionization in aqueous solution, the hydrophilic group has strong positive electrical property. It is characterized by broad-spectrum sterilization, low effective concentration, efficiency, stability, water solubility, being non-foaming and other excellent properties. It is a non-toxic, colorless, odorless, biodegradable and environmentally friendly high-molecular germicide, therefore is widely used and shows a good application prospect in oilfield, industry, agriculture, medicine and daily life. 

 

BIW and BCW are two kinds of compound germicides that are developed for the purpose of oilfield sewage treatment. They are compound with different quaternary ammonium salts and nonionic non-oxidizing germicides and have special effects on sulfate reducing bacteria (SRB) in oilfield sewage. It can still achieve a good germicidal effect which is 1-3 times that of the use of single germicide, if used in sewage with complex water quality, such as high-polymer-bearing sewage produced by tertiary recovery.
