A method for forming a filter for passing contaminated water using elements that are made wholly or partly of degradable material. The increased area available for flow is obtained by providing a first media for which the increase in area for passing the contaminated water is desired, adding a second media comprising of a plurality of degradable elements, and allowing the elements of to degrade to bring about an increase in the area available for passing the contaminated water.

A method for forming a filter for passing contaminated water using a device and one or more media. The device comprises of one or more elements that are capable of undergoing degradation. The increased area available for flow is obtained by adding a first media to predetermined areas of the device and allowing the elements to undergo degradation to bring about an increase in the area available for passing the contaminated water.

Devices and methods associated therewith for facilitating movement, removal and/or installation of components from treatment units (e.g., water treatment units and wastewater treatment units). The treatment unit can take the form of a granular media filter (e.g., upflow filter, downflow filter or bi-flow filter) or a sludge collection basin. One preferred device is one or more floats facilitating safe removal of components of a treatment unit. The float(s) can be operably associated with an air scour system of a water filter to remove the air scour system from a granular media filter bed. The float(s) can be operably associated with a collection grid of a sludge collection container facilitating safe removal of the collection grid from the sludge collection container. Another preferred device is a flexible piping/conduit operably connected to a pressurized air source and an air scour system to assist in removal/installation of the air scour system.

An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.

An aquarium skimmer device can include a filter body that attaches to a water pump, filter, or power head, wherein the filter body is configured to hold a filter medium for filtering water that passes through the filter body. The skimmer device can also include a funnel holder that attaches to a top of the filter body, and a funnel assembly comprising a funnel. The funnel assembly can be received by the funnel holder and configured to float up and down with respect to the funnel holder with changes in water level, and a wide opening of the funnel is positioned one inch or less below a surface of the water.

The present invention solves the problem of environmental pollution created by animal waste and converting animal waste to reusable water in the earth. The invention does this by a device that is capable of receiving animal waste and breaking down the waste into different components by the help of a decomposing catalyst such as a septic pack, filtering the resulting solution and finally producing a filtered liquid that enters the earth being cleansed by the process. The present invention comprises a filter device, a tank unit, a filter unit, a first opening positioned on a top surface of the tank unit; a second opening positioned on a bottom surface of the tank unit; wherein the tank unit is capable of receiving animal waste through the first opening; at least one hole at a bottom surface of the filter unit; wherein the tank unit is placed over the filter unit.

The invention relates to a clearing apparatus (I), especially for clearing and/or maintaining of filter basins (7), consisting of at least one carrier (1), at least one undercarriage (2), at least one removal device (3), at least one driving device (4) and at least one pushing or guiding device (10), wherein the removal device (3) is situated in the front and/or before the undercarriage (2) and/or in front of an axle (21) of the undercarriage (2) in the travel and/or removal direction (a), the pushing or guiding device (10) is provided at the rear in the travel and/or removal direction (a), and wherein the removal device (3) comprises a platform (32) on which a drivable or driven removal means is circulating, such as a drivable or driven flexible circulating chain (31) and/or a flexible circulating belt (31), in order to remove material from a bottom (71) of the filter basin (7), transport it away and/or dispose of it.
