Upgrading the quality of incoming or outgoing water streams

Clarification is the removal of contaminants from incoming water to make it suitable for potable or industrial uses, or from outgoing water to ensure compliance with regulations concerning discharge or reuse.

With regard to influent water, GE Water & Process Technologies offers treatment programs that remove organic color, calcium and magnesium hardness, iron, and suspended solids, using exclusive blends of custom-designed polymer formulations for specific applications. These polymers - available as liquids, emulsions or powders - help eliminate the need for pH adjustment, decrease load on demineralizers, increase filter throughput, and significantly reduce sludge volume. Influent clarification can:

	Improve efficiency in boiler and cooling systems
	Improve the performance of scale inhibitors
	Improve process operations
	Produce cleaner, clearer drinking water.

GE also offers the industry's most technologically advanced and comprehensive resources to make effluent or wastewater acceptable for reuse or discharge. Polymer treatment programs improve effluent clarity in primary clarifiers and accelerate the settling of suspended biological solids in secondary clarifiers. Polymers and dewatering aids also reduce the volume and moisture content of sludge, minimizing the problems and costs of solid waste disposal. Benefits from effluent/wastewater clarification include:

	Reduced fouling by solids, organics, microbiological materials and colloids
	Increased settling rates
	Reduced sludge volume
	Reduced odors.
