The present invention supplies partitioned water treatment systems that possess a plurality of chambers and vertical filtration units, and are operative to control and filter surface runoff water. Such systems are typically placed inline with surface runoff water conveyance system infrastructure, such as pipes, channels, and water storage units.

Systems and modular devices for roof or ground-level stormwater management are disclosed. A modular stormwater management device includes a water retention mat structured to absorb stormwater, a rigid frame structured to support the water retention mat, and a perforated surface structured to permit drainage of the stormwater from the water retention mat through the perforated surface.

An oil stop valve assembly for allowing a flow of water and blocking a flow of oil has a body having an inlet and an outlet, a seat formed adjacent to the outlet of the body, and a float positioned in the body. The float has a specific gravity of between 0.90 and 0.95 so as to be buoyant in water and to sink in oil. The float is away from the seat when a level of water within the body is above the seat. The float is seated in the seat when the level of water in the body is adjacent to the seat. The body is positioned in a container having a fluid inlet and a fluid outlet. The fluid outlet of the container is connected to the outlet of the body.

An F.O.G. separation apparatus includes a tank for receiving a liquid effluent flow containing water, F.O.G., and gross solids. The tank has a chamber, an inlet in an inlet module, a downstream section and an outlet in an outlet module. The inlet module has a weir for the effluent downstream of a strainer to strain gross solids from the effluent. A pump upstream of the strainer pumps water and solids that do not pass through the strainer. The pump's rotatable vertical shaft has a motor at an upper and an impeller at the bottom. A pipe connected to the inlet module near the impeller conveys solids and water when the pump is activated and directs the solids and water to the outlet. F.O.G. and water entering the tank pass to the downstream section where the F.O.G. is removed from the water by a skimmer, and the residual water exist the tank through the outlet module.

A conduit assembly of a gravity separation device having specialized joint structure for mating first and second conduits to permit easier removal of the first conduit. The first conduit may include a snout having a tube and a collar positioned at an end of the tube. The collar may include a flange extending outward from a center of the tube. The second conduit may have a main body and a saddle at an end of the main body. The saddle may include a track shaped to receive the flange of the collar of the first conduit. The saddle may also have a resiliently separable gateway comprising two opposing projections configured for receiving therebetween and partially enclosing the tube of the snout.

A filtration system having a malleable compartment and a handle. The malleable compartment has a permeable fabric forming an exterior of the malleable compartment. The exterior at least partially faces a contaminated fluid. The permeable fabric has a pore size that defines the permeability of the fabric. The malleable compartment also has an interior that holds an interchangeable microfiltration medium. The microfiltration medium has a pore size that is smaller than the pore size of the permeable fabric. The filtration system also included a handle that is affixed to the malleable compartment.
