A connector for axially fixing a module or support of a module to an elongate pipe has a central web with a rear flange extending from a rear edge and a front web extending from a front edge. The web may be partially cylindrical with the flanges extending radially. The web is sized and shaped to mate with the outer surface of the cylindrical pipe and extend through a hole in the module support with the rear web against the rear face of the support and the front web against the front face of the support. A fabric layer is wrapped around the outside to conceal the support and connector. A fluid treatment unit with spaced apart modules utilizes the connector to fix the modules axially to the pipe with a fabric layer concealing the support and connector.

A removable catch basin filter insert includes a filter container is fitted into a catch basin in the ground at the location where the stormwater exits the gutter and enters the stormwater sewer system. The removable catch basin filter provides pollution capture from stormwater while being easily cleaned. A hinged cover is included at the top of the filter insert to allow the captured pollutants to be evacuated through the use of a vehicle or being tipped nearly upside down by a mechanical arm. A hinged trap door is included at the bottom of the filter insert to allow captured pollutants to be evacuated through the bottom of the device and into a container. By capturing the pollutants with the removable catch basin filter insert before the pollutants enter the mainline storm drain system, clean storm drain systems are provided allowing for cleaner waterways.

A rain water filter is disclosed. The rain water filter includes a horizontal inlet and a horizontally arranged residual water outlet which are slightly offset in relation to each other. A pipe with a longitudinal slot connects to the inlet and the pipe leads into the residual water outlet. An adhesive filter which is in the form of a tunnel-shaped half-shell is arranged below the longitudinal slot, where the lateral walls are the filter surfaces of the filter. Due to the adhesion effect, the water which flows past is suctioned inwards where it passes through the longitudinal opening into a tank and from there, for example, into a cistern via a filter water outlet. The water running off from the side walls is collected on the base of the hollow cylinder and from there is guided to the residual water outlet.

The present invention relates to a device (1) for filtering storm water inside a storm drain. The device (1) comprises a filter unit (2), a metal capturing ballast unit (6), and a floating carrier (4) for carrying the filter unit and the metal capturing ballast unit (6). Whereby, in use, the device (1) is arranged in a floating condition in the storm water of the storm drain. The filter unit (2) is at least partially arranged above a surface (5) of the storm water, and the metal capturing ballast unit (6) is arranged below the surface (5) of the storm water. The metal capturing ballast unit (6) comprises a solid material for capturing metal and providing ballast.

An inventive apparatus induces a vortex in a liquid flow (e.g., storm-water runoff) to remove particulates from the liquid. The apparatus can be inserted into a tubular portion (e.g., a manhole) such that a sump region is located below the apparatus. The apparatus includes a base and a weir extending upwardly from the base. The base has a first region including a funnel shape with a sump inlet aperture. The base also has a second region including a sump outlet aperture and optionally a sump access aperture. The weir separates the first region from the second region.

Methods for capture of biogas from a wastewater system are disclosed herein. The methods may include the step of collecting biogas within a collector chamber of a biogas collector formed at an elevated location in a wastewater system, the biogas being released from wastewater passing though the collector chamber. The methods may include the step of controlling the withdrawing of biogas from the collector chamber, and the step of capturing the biogas withdrawn from the collector chamber. The methods may include performing the step of collecting biogas within a collector chamber of a biogas collector by reducing a pressure within at least portions of the collector chamber. The methods may include the step of conveying biogas withdrawn from the collector chamber to a biogas disposer. Related apparatus for capture of biogas from a wastewater system are disclosed herein.

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.

A liquid cleaning and watering system for living plants rests on a surface covered by a non-porous material. A plate layer covering the non-porous layer has two or more layers, each layer having runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of liquids into the liquid cleaning system. As the living plants are watered or cleaned, excess liquids containing water and oils that were excreted by the living plants enter the liquid cleaning system through the holes, the liquid traverses the grid layers, flowing towards a drain. Contaminants within the liquid collect within the grid of the layers of the plate layer for later disposal.

A modular liquid waste treatment system is disclosed. In accordance with some embodiments, the system includes a central distribution unit and one or more treatment fins in flow communication therewith. The distribution unit may be configured to receive liquid waste from a given source and distribute that waste, at least in part, to one or more treatment fins. In turn, bacteria present in a given treatment fin treat the liquid waste, and the resultant treated liquid may drain from the fin to the surrounding environment. In some embodiments, a given treatment fin may include porous media providing a large surface area on which bacteria may grow to facilitate treatment. The system may be installed in and/or above the ground, and in some cases may be surrounded, at least in part, with treatment sand and/or other treatment media. The system may be used in aerobic and/or anaerobic processing of liquid waste.
