FOG removal from wash water and wastewater in industrial

FOG in water is often unavoidable but has costly effects if left unaddressed. There are solutions for removing FOG from water that can improve wastewater treatment processes, reduce maintenance and downtime and even create an opportunity to sell recovered oil. Common solutions include oil skimmers, oil-water separators or a combination of both.

Removal of colloidal solids - ScienceDirect

CHAPTER 6 Removal of Colloidal Solids The reason that colloidal constituents in industrial waste are so important is obvious. In those constituents, wastes containing only a quarter of total solids in the form of colloids also account for as much as 50% of the total biochemical oxygen demand (BOD).

Lagoon Pumping and Dredging, Inc. - Removing Solids

Typical animal waste lagoons with a 50-50 top water to solids ratio will produce between 12% to 16% solid content in the slurry. Pumping solids is very abrasive to the pumps and hoses so heavy solids will cost more to pump. However, the cost to remove heavy solids is less than pumping more gallons of effluent with a lower percent of solids.

Wastewater Treatment - water, effects, environmental, pollutants

A settling pond, usually man-made, collects and slows water flow so that suspended solids (sediments) have time to precipitate or settle out of the water. Some applications of settling ponds include capturing runoff from farms (agricultural waste), construction projects (soil sediment) and mines (sediment and toxic waste).
