A cleaning bucket structure for automatically purifying foul water is provides. The cleaning bucket structure includes an outer bucket, an inner bucket, a transmission member, a pumping member, a filtering member and a covering plate. The outer bucket has a receiving space. The inner bucket has a diameter which is smaller than a diameter of the outer bucket and is disposed in the receiving space of the outer bucket. The transmission member is disposed in the inner bucket. The pumping member is disposed in the inner bucket for receiving the transmission member therein. The filtering member is disposed in the inner bucket and surrounding the transmission member and the pumping member. The covering plate is disposed in the inner bucket and above the filtering member and includes a plurality of openings.

A floatable filter has an outer member that has a top section and bottom section that are hollow. The top section has an inner edge and an outer edge with the outer edge having a diameter that is adapted to slide up and down an inner diameter of a storage container. Connected to the inner edge of the outer member is an internal grid. The internal grid includes members that crisscross to provide spaced openings. Further, the internal grid dwells in a plane below a horizontal plane of a top surface of the top section.

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

A core sheet includes a primary textured surface and separate secondary cuspations or corrugations. The core sheets are configured for use within a fluid or wastewater treatment unit that typically includes one or more fabric layers. The primary textured surface enhances retention of wastewater fluid received by the unit, which over time causes an increase in build-up of biomatter on the surface, which in turn enhances the efficacy of treatment of the wastewater.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.
