COD Degradation Agent GC-993
浏览: 发布日期:2019-03-22

Product nature:
 
Appearance:                 Light yellow solid (diluted with water)
Specific gravity:            1.35-1.40 (25 C)
Acidity and alkalinity:    weak acidity
Active component:        > 80% (including oxidant, COD remover, coagulant, etc.)
Applicable PH Scope:   5-7
Selectivity:                   It mainly aims at dewaxing and deoiling solution discharged from pretreatment of electroplating. It is also suitable for ordinary wastewater treatment with COD less than 500.
 
Usage method:
 
Low COD wastewater (less than 500 ppm): GC-993 is diluted and added directly to the wastewater catchment tank, and the discharge standard can be achieved by subsequent conventional treatment.
High COD wastewater (15000-30000 ppm): COD demulsifier GC-992 was added to acidified high concentration wastewater tank, and then added to GC-993 for continuous stirring reaction. The reaction time was about 2H. After the wastewater is stationary, the supernatant can be discharged to the standard by secondary treatment.

Processing flow:
 
Catchment tank - PH regulating tank (adjusting PH = 2-3) - - action tank (adding demulsifier GC-992, reaction 1H) - - deoiling tank (removing suspended oil on the surface) - - PH regulating tank (adjusting PH7-8, adding COD catcher GC-993, reaction 0.5H) - - action tank - flocculation tank - pressure filter (sludge collection) - - integrated wastewater tank (pressure filter water) - - secondary treatment - - discharge water or reuse up to standard Sink.
