Portable particulate filtering system and method

A filtering device for removing particulates from waste water, comprising:

• a base plate, the base plate including a waste water inlet, wherein the base plate has a lower sealing surface of an annular outer frustoconical shape adapted for contacting an upper edge of an inner surface of a flexible filtering vessel;
• a flexible filtering vessel formed of flexible filtering material, the vessel having a conical shape, wherein the upper edge is adapted to contact the lower sealing surface of the base plate, and wherein the flexible filtering material has pores of a size sufficient to allow liquid to pass through the material but to prevent particulates of a specified size from passing through the material, permitting particulates to accumulate on an inner surface;
• a mounting and sealing structure comprising a retaining ring with an inner frusoconical surface adapted to contact an outer surface of the upper edge of the flexible filtering vessel;
• and
• the mounting and sealing structure further comprising a plurality of fasteners adapted to draw and hold the retaining ring and the top plate together, trapping an upper edge of the flexible filtering vessel therebetween, forming a liquid seal.

A portable filtration system for treating a slurry of water with particulates, comprising;

• a cart configured to retain and transport the filtration system;
• a pneumatic slurry pump mounted to the cart, the slurry pump having a slurry inlet, a slurry outlet and a pressurized air inlet;
• a base plate mounted to the cart, the base plate having a liquid inlet for receiving liquid from the slurry pump outlet;
• a flexible filtering vessel affixed to a lower sealing surface of the base plate;
• and
• a mounting and sealing structure for mounting the flexible filtering vessel to the base plate and sealing an upper edge of the flexible filtering vessel to the base plate,
• wherein the flexible filtering vessel is mounted at a height sufficient to permit water that passes through the flexible filtering vessel to fall into a clean water capture system.
