20100108594 | SELF-CLEANING INFLUENT FEED SYSTEM FOR A WASTEWATER TREATMENT PLANT - An influent feed system for directing the influent liquid via hydraulic energy to scour the surface of primary treatment tank walls and base to move the scoured solids to a sludge trough. Scouring action takes place during periods of low liquid levels in the tank. The system comprises two identical, adjacent tanks sharing a common distribution box. Either or both of the tanks are in use at any given time. The tank in use will be empty occasionally each day. Influent feed troughs disposed transversely in each tank directs solids towards a sludge hopper in the tank bottom. The IFTs extend over the width of the tank to provide scouring of the entire end wall and floor surface. Each IFT has a sump with a valved discharge piped directly to the sludge trough, and the floor of each IFT is sloped towards the sump to facilitates draining of solids. | 05-06-2010 |

20150068969 | Mobile Fluid Clarifying System - Apparatus for removing solids from a liquid/solid mixture includes a plurality separation compartment formed by a plurality of weir partitions. According to one aspect of the invention, a lamella clarifier is positioned within one of the compartments. According to another aspect of the invention, a drain trough extends along the bottom of the apparatus and a plurality of drain pipes are connected to the trough. The drain pipes are connected to a common manifold pipe which in turn is connected to an inlet of a pump. The pump may be activated to remove separated solids that accumulate in the trough at the bottom of each compartment. | 03-12-2015 |
20150300565 | FILTER DEVICE - A filter device may include a filter housing and a filter element defining a longitudinal axis disposed in the filter housing. The filter element may be configured to be penetrated by a fluid flow in a radial direction from a raw end to a pure end of the filter element. A water separator may be disposed at the pure end of the filter element and arranged axially spaced from the same. The water separator may have a hydrophobic and annular diaphragm extending in an axial direction of the filter element configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow. | 10-22-2015 |
