Mechanical Lattice filters

NPO Decanter produces mechanical gratings of several types: rake, drum and stepped.

The rake grate is a filter cloth assembled from rods inserted into a frame over which stainless steel plate chains move along polymer guides. Transverse rakes are fixed on the chains, designed for constant cleaning of the filter cloth.

The rods of the filter grate have a close to teardrop-shaped cross-section, which improves its hydraulic characteristics. The grate on a special stand is fixed in the channel and can be raised for maintenance.

In drum-type lattices, wastewater flows into the inner part of a rotating drum with perforated walls installed at a slight angle. Due to the loss of water through the perforated walls, the wastewater stream is concentrated and removed from the opposite part.

Installations in which wastewater passes sequentially through a set of canvases with holes decreasing from step to step are called stepped grids.

All mechanical grids of NPO Decanter are made of corrosion-resistant steel, in several standard sizes, which are calculated based on the required throughput, the composition of wastewater and the geometric dimensions of the supply channels.
