Big bowl decanter centrifuge is a major separation equipment for oil sludge treatment. GN Solids Control makes 2-phase decanter centrifuge for liquid and solids separation, and 3-phase decanter centrifuge for water, oil and solids separation. The centrifuge bowl sizes are vary from mini size 9 inch to big bowl 22 inch size and the largest big bowl 30 inch.

Last week, some sets of GNLW554ET- VFD decanter centrifuge were shipped to an clients doing oil sludge treatment. GN Solids Control makes T Series Decanter Centrifuge mainly for dewatering treatment and for thickness.

GN T series decanter centrifuge for dewatering / Thickening is with beach angle of 8.5 degree. It is widely used for maximum dewatering requirements of municipal and industrial waste water sludge. The dewatering decanter centrifuge is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with T series decanter centrifuge.

Applicable Material of GN Solids Control T Series Decanter Centrifuge can be used to treat below materials, but not only limited to them: Drilling mud, environmental protection sewage, oily sludge, cutting fluid, sand washing water, mineral washing water, soda white mud, salt mud dewatering, magnesium aluminum emulsion, steel-making waste water, precision casting waste water, construction mud, tunnel mud, mine waste water, industrial waste water, organic waste water, aquaculture waste water, chemical industrial waste water, printing and dyeing waste water, municipal sewage, river sludge, water plant sludge, lake sludge, kaolin grading, calcium carbonate, bentonite, Silica, titanium dioxide, calcium sulfate, barium sulfate, conductive film glass polishing solution, aluminum hydroxide, cryolite, silicate, oil sand separation, landing oil, oil sludge, coal tar, inorganic fertilizer, Chinese medicine extraction such as taxus chinensis, honeysuckle and liquorice, clarification, concentration and dehydration of salt crystals, etc

The most popular bowl size used for oil sludge separation is 9 inch, 14 inch and 22 inch decanter centrifuge. For the 3 bowl sizes, GN Solids Control has 2 model series to suit for different material situation. The 2 model series are defined per the ratio of bowl length and bowl diameter. GNLW223, GNLW224, GNLW363, GNLW364, GNLW553, GNLW554.

Regarding the 3 bowl diameter 9 inch, 14 inch and 22 inch decanter centrifuge, the ratio of bowl length and bowl diameter can be 3 or 4. The ratio 3 serials decanter centrifuge can be used for oil and gas drilling fluids treatment. The ratio 4 decanter centrifuge is specially designed for oil sludge treatment and waste water, waste oil treatment.
