C8E – large-scale sludge dewatering and thickening processes
A key component of the treatment process for drinking water and wastewater is the efficient separation and dewatering of fine-grained sludge, using mechanical means whenever possible. In particular, large wastewater treatment plants serving a population of 200,000 or more must find the most economical, optimal solution for the dewatering and thickening process. Given this imperative, reliability, ...

Prefiltration (SDI reduction) for Reverse Osmosis Boiler Makeup Water System - Case study
Background A major electrical utility in the Lake Charles Louisiana area required high quality water for boiler feed makeup water. A ground water pumping station provided 1,500-gpm water flow to a chemical treatment and solids clarification system. The decant water from the clarifier (SDI 6 to 8) collected in a lift tank where the water was pumped to two, parallel processing, carbon steel, ...

Centrifuge Technology in Drilling Fluid Recycling
Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned fluids. HDD ...

VSEP beats decanter centrifuge at solids removal from ethanol biomass
As the world searches for fuel alternatives to gasoline, a clear candidate to lead the way has emerged, Ethanol. Ethanol production for use as a fuel additive (or to be used directly as a fuel source) has grown in popularity due to governmental regulations and in some cases economic incentives. Both regulations and incentives seem to be based on environmental concerns as well as a desire to ...

Gold Recovery-1
The manufacturing of jewelry is comprised of molding to form the jewelry followed by a polishing step, then deburring or ultrasonic cleaning. These steps leave residual gold in the rinsing and ultrasonic cleaning waters. To recover the gold, industries use the FloccinAgentstm for a one step liquid/solid separation process. The process is to collect all of the wastewater into a mixing container. ...
