The average rate of glass particle mixing into waters is 6g/hr and the flow rate of wastewater stream is 10m3/hr. The target concentration of the glass particles is around 350-1000mg/L.
Dear Jai Sankar Seelam,
An efficient method to remove glass particles from glass fabrication and grinding wastewaters is the centrifugation (centrifuge) method. There are to companies that can supply such aystems:
CENTRI-FLOW SYSTEMS

CentraSep

Hoping this will be helpful,
Rafik
The installation costs are high in centrifugal system. Can you please suggest any chemical based methods?
Dear Jai Sankar Seelam,

System for wastewater treatment
US 7238283 B2
A new and improved wastewater treatment system suitable for the treatment of wastewater from a CMP process. A holding tank receives wastewater from a CMP wastewater collection tank. The holding tank may further receive wastewater from a backside grinding (BG) wastewater collection tank. A reaction tank receives wastewater from the holding tank. A coagulant polymer binds to the slurry particles in the reaction tank to precipitate the slurry particles out of solution. One or a pair of clarifiers receives the wastewater from the reaction tank, and the polymer-bound slurry particles are separated from the wastewater in the clarifier or clarifiers. An effluent collection tank receives the purified wastewater from the clarifier or clarifiers. The purified wastewater may be pumped to a storage tank such as a reused city water (RCW) tank for use in scrubber cleaning processes, for example.
