Water Tecnik Ltd. products

A no-moving part unit that cascades solid laden slurry down a wedge wire screen to separate solids from liquids. The slurry is pumped or gravity fed into the unit’s top chamber, flows over a full width weir and cascades down the curved screens surface. The liquid passes through the screens voids into a collection chamber below. Solid particles larger than the screens void size stay on the surface, and as this accumulating mass increases in weight/volume, gently slides down the screens surface, compacted and further dewatered as it travels down. At the bottom discharge chute, the solids simply drop off or in some applications, go for further dewatering by a drum or screw press unit. The static screen version has it screen rigidly fixed in position whereas the other, more efficient unit, has its screen mounted to enable a small motor to vibrate it. Static and vibrating options, each with 6 capacities up to 250 m3/hr.

The External Fed Drum Screen is a machine for the fine screening of sewage coming from industrial or civil purification plants, or for the screening of process waters coming from industrial transformation plants.

The Internally-fed Rotary Screen is composed of a tank and a spiral connected to the drum for the transport of screening. The screen is composed of a perforated plate whose holes diameter is as big as the desired openings size. The drum is supported by nylon wheels, and it is operated by a gearbox. The filter is fed through a nozzle placed in the front of the machine. A diffuser spreads the water on a large area of the screen which, rotating, separates water from the organic particles contained. The filter is cleaned by means of a washing system composed of a tube equipped with spray nozzles for pressure water.
