Greywater control parameters
Thread Content
Dear experts: What indicators are considered important when it comes to the ash water from coal-water slurry gasification?
Total phosphorus, chlorides, calcium ions, pH, conductivity, total hardness, suspended solids, alkalinity
Personally, I think the main ones are pH, hardness, turbidity, and chlorides
SS turbidity, total hardness, alkalinity, COD, ammonia nitrogen – these mainly affect the operation of the gasification process as well as the overall operation of the plant
The seniors on the 2nd and 4th floors explained it in great detail
Scale-inhibiting dispersants are divided into phosphorus-containing and phosphorus-free types, with the total phosphorus level generally being controlled between 3-5 mg/L through the amount added. The amount of dispersant added can also be determined based on the total phosphorus content.
