Abstract: A filtering apparatus for filtering sand, other debris, and pollutants from rainwater does not utilize electricity or complex valves. The apparatus includes a tank, preferably concrete, having at least one inlet, an overflow outlet, and a filter proximate the tank outlet. The overflow outlet in one embodiment comprises an overflow weir having at least one side and an open top. A screen is attached to the top of the overflow weir and/or the tank outlet, and is preferably made from stainless steel or plastic. The screen is preferably sized to filter sand. In use, rainwater enters the tank, debris settles, and water exits the outlet and the filter. When a large amount of fluid enters and fills the tank, the fluid level reaches the overflow. At this point, any excess rainwater that cannot exit through the screen will flow over and into the overflow opening and exit the tank outlet.

Abstract: A wastewater treatment system is disclosed whereby trickling filters remove a high proportion of biochemical oxygen demand, total suspended solids, and nutrients from wastewater using, in one embodiment, a pressurized media container. The system accomplishes this in an improved way by combining venturies or blowers to aerate the wastewater, and recirculating the wastewater and air down through the treatment media, improving the overall efficiency of the system and reducing its size. A screen at the base of the pressurized media container supports the media and allows the wastewater to exit the pressurized media container. The system also includes a low pressure nozzle that aids in the proper distribution of the wastewater.
