Drum Thickener Line B Line
Sludge is from primary or secondary clarification or both. Whether the sludge is to be dewatered, digested or simply transported away for further treatment, it is far more economical to concentrate the suspended solids in the least possible amount of water.
Canamidex/OCM Drum Thickeners are optimal for basic, cost-effective mechanical sludge thickening through a slowly rotating drum filter. Sludge with as low as 0.4 percent dry solids content can be easily and economically thickened from 3.0 to 12.0 percent with the aid of a modest amount of polyelectrolyte. This enormous volume reduction will help plants keep costs down as less volume has to be handled, increasing the efficiency of the digesters or reducing tanker loads per day.
The sludge to be thickened – mainly water – is mixed with the necessary amount of polymer. Mixing turbulence and contact time is allowed in order to create large, stable flocs and clear water. This is then gently fed to one side of the drum over and through a polyethylene filter cloth. The solids travel axially to the exit at the opposite end of the drum while the drum turns at a very low speed. Excess free water is drained along a filter cloth and collected at the bottom of the casing to exit via gravity
The sludge concentration can be regulated by adjusting the feed rate, angle and speed of the drum. Canamidex/OCM drum thickeners are designed for relatively low-throughput thickening requirements in waste water treatment plants (WWTP). Made entirely of stainless steel, they complete our thickening portfolio to provide the most economical solution for most thickening problems.
Drum thickeners are well known in small waste water treatment plants (WWTP). Economic design is combined with high efficiency. The small footprint of this machine type and its enclosed design not only provide an efficient thickening process, but also minimize emissions to the environment.
