Liquid caustic soda

產(chǎn)品特性 

Liquid caustic soda is also the liquid form of sodium hydroxide. The reaction speed of liquid caustic soda is relatively fast, and it is easy to crystallize at ultra-low temperature, which requires high operation. The concentration of liquid caustic soda for industrial use is generally 30% - 40%, and the specific concentration depends on the characteristics of the wastewater to be treated. It can be adjusted at any time according to different regions and wastewater characteristics.

適用范圍

Each sewage treatment plant will use liquid alkali as sewage treatment agent. Acid and alkali neutralize and adjust PH, precipitate heavy metal ions, assist in removing fluoride ions, and improve demulsification and coagulation effects, with low cost and good effect. Reasonable use of sodium hydroxide will make the sewage clearer.
