Sand Filters, Omegafilter NG

Kingsley Industries offers continuous, self-cleaning Sand Filters, Omegafilter NG, a machine constructed simply without mechanical moving parts. Reliability, high efficiency and continuous operation are its main characteristics. Operating principle: the water to be filtrated is introduced in the lower area of the sand filter through a special designed cone that distributes evenly the inlet water into the sand bed made of quartzitic sand. The water, flowing through the sand bed, settles the solid particles contained and conveys to the upper part of the filter where is discharged by an overflow. The contaminated sand is pumped to the washing device where is continuously washed using a small fraction of already filtrated water, that is then collected to a separate outlet. The cleaned sand is again replaced at the top of the bed. The special design of the distributing cone of Omegafilter NG, assures a homogenous, distribution of the water to be treated in the sand bed. This results in a uniform up-flow stream of the water from the bottom to the top with higher filtration efficiency. The exclusive sand washing device used in the Omegafilter NG, represents the heart of the system. Located at the upper part of the filter, it receives a mixture of water and contaminated sand coming from the conical lower part where an airlift sand pumps system is installed. While the sand slowly flows down into the washing device, a small quantity of filtrated water moves upward in counter current within the washer, conveying to the surface the solid particles previously separated by the sand. The regenerated sand falls down to the top of the filtering bed while the washing water and the solid particles flow out by a different outlet. The washing system above described, allows a continuous cleaning of the sand and consequently a well-balanced and very low drop loss. Applications: polishing of clarified waters for recycling, surface and spring waters filtration, polishing of process waters for recycling, biological plants effluents filtration, algae removal, filtration of oily waste waters, filtration of iron and steel industry waters, filtration of metal finishing waste waters, etc.
