Raw Water Pretreatment

Graver offers you a comprehensive line of process equipment in the industrial market to treat water coming from sources such as rivers, lakes, groundwater or seawater.  Proper design and application of proven technologies is critical at the beginning of your water system.

Traditional Clarification – The Graver Reactivator® is a high rate, solids contact, sludge recirculation type clarifier that, in minimum time, space and chemical consumption, produces an effluent of the highest quality. It is used principally for clarification, lime softening, silica reduction, or organics reduction of water and wastewater containing suspended solids, color and organic impurities. As such, the Reactivator provides a means for chemical addition and mixing, flocculation, and upflow clarification in a single unit.

Inclined Plate Clarification – The Graver Lamella design assures laminar flow conditions that result in hydraulic uniformity and high effluent quality. It permits great reduction in the space needed for clarification equipment, and allows the compact equipment to be located indoors if desired, or to be easily relocated at a later date. It also makes point-source treatment not only feasible, but logical for many applications.

Gravity Filters – Graver offers several different types of gravity type filters. Each type offers a unique advantage to help address your specific water treatment needs. Graver’sMonoscour® for example is a heavy duty, high rate gravity filter designed for treating high turbidity loads and sticky particulates such as those typically encountered following chemical treatment with polymers and coagulants. TheMonoscour filter is particularly useful in wastewater applications, lime softening applications, cooling tower side stream filtration and all other gravity filter applications where high filtering rates are desirable.

Pressure Filters – Graver Pressure Filters have proven their ability to meet any water filtration problem efficiently and economically in hundreds of installations worldwide, and in a wide range of industrial plants, municipalities and utilities. Graver Pressure Filters are available in vertical and horizontal designs, in any convenient size, and with valve arrangements to meet any custom or special requirements.
