Click to chat· The deep cone thickener with the diameter of 1 m was used for industrial tests. The slurry used in industrial tests was supplied by the beneficiation plant of Yinshan Copper Mine. Because the slurry concentration is approximately 10 vol. recycled water is used to dilute the slurry and the diluted slurry is pumped into the deep cone thickener.
Click to chatPaste Thickeners can help producers eliminate the need for settling ponds and other structures. They are meant to achieve the highest solids concentrations possible through gravity separation. The resulting mud described as a paste is often so thick that it becomes non-segregating — no further separation of water and solids can be achieved. As a guide a paste material is measured with a
Click to chat· DEEP CONE THICKENERS deep cone thickeners are designed and constructed to give optimum performance and reliability in even the toughest applications. The deep cone provides a smaller footprint than a rake style thickener saving space on site. The thickened sludge underflow can reach solids content of over 50 .
Click to chatDEEP CONE AND HORIZONTAL RAKE THICKENER. The clarification process is essential to a wastewater treatment plant. Unlike the filtration carried out by the filter press the clarification is a continuous process that separates water from the solid particles suspended into it. Matec can provide customers with any type of decanters by designing
Click to chat· The pilot deep cone thickener in this work was multifunctional with a feedwell a rake and an underflow circulation pump. Thefeed slurry and flocculants solution were pumped into the feed welltogether to ensure the particles were flocculated. Also the pilot thick-ener introduced a raking system and underflow circulating systemin order to simulate real thickener operation.
Click to chatDeep Cone Clarifier Components The water is pumped into the slurry decanter the slurry precipitates under the effect of the flocculant to the bottom of the cone. The slurry settled in the decanters falls through the automatically-opening pneumatic valve (normally closed) into the steel tank below to be homogenized.
