Keweida has long been committed to the development and application promotion of industrial wastewater reuse and discharge technology, introducing advanced foreign technology and developing and improving a set of negative pressure solid-liquid separation technology. The principle of this technology is to use the principle of gasification temperature difference between substances in the waste liquid, combined with physical centrifugal stirring and steam filtration condensation purification and recovery technology in the negative pressure chamber, to purify, condense and recover the water after vaporization, which contains a large amount of inorganic salts COD、BOD、 The solidification and discharge of heavy metal substances; Suitable for processing high concentration industrial waste liquids outsourced by factories, and can also further dehydrate and dry the high concentration waste liquids discharged from traditional evaporation equipment, achieving solid-liquid separation. Thoroughly solved the drawback of traditional evaporation equipment being unable to solidify and still requiring specialized equipment for crystallization solidification; It has achieved true emissions and played a significant role in reducing industrial waste, reusing waste liquids, and recycling resources.
