The main board includes a first curved surface and a second curved surface arranged opposite to each other and that are configured to form a double elliptical cross structure having a cavity. The first piece, the second piece, and the accessory piece are respectively fixed in the cavity of the main board. The first and second pieces are perpendicular to each other, and the accessory piece is parallel to the second piece and perpendicular to the first piece. The plurality of first through holes is arranged on the main board; the plurality of second through holes is arranged on the first piece and/or second piece.

A urban waste water treatment plant, comprising: a tank subdivided in at least two distinct portions, said at least two distinct portions comprising at least an accumulation area of the sludge and at least an accumulation area of the liquid phase; at least a feeding pipe of the waste water to be treated; at least a recirculation pipe of the liquid phase; at least a discharge pipe of the effluent treated, withdrawn from at least one area of the liquid phase, characterized in that said feeding pipe of the waste water to be treated is configured so that the waste water is inlet on the bottom of said at least one sludge area and in discontinuous mode; inside said at least one sludge area it is provided porous material, contained between two containment planes, configured to allow the filtration of the waste water with removal of the suspended material.

The present disclosure relates to a filter apparatus (1) for mechanically filtering a liquid (W). The filter apparatus (1) includes a filter chamber (5) for containing a plurality of filter elements (7) that form a filter pack (29) for filtering the liquid. The filter chamber (5) has a liquid inlet (12) and a liquid outlet (14). The filter apparatus (1) includes means for introducing air into the filter chamber (5) through one or more air inlets (25) to agitate the filter elements (7). The filter chamber (5) is substantially sealed and the air introducing means (22) may be configured to draw air into the filter chamber (5) as liquid is drained from said filter chamber (5). In certain embodiments, the filter chamber (5) may have a substantially constant profile or a substantially continuously tapered profile along its longitudinal axis (X-X). The present disclosure also relates to methods of filtering a liquid (W).

A system for wastewater treatment includes a reactor for nitrification of wastewater in a body of water. The body of water has an influent end and an effluent end. The reactor is positioned at the influent end of the body of water, and has a reactor inlet adapted to receive at least a portion of the wastewater from the effluent end of the body of water or from at or near an outlet of the system.

A method to continuously stabilize and cool effluent temperatures in FOG (Fats, Oils and Greases) discharged into Grease Traps (GT) or Grease Interceptors (GI). Temperature stabilization/cooling became necessary with the introduction of water efficient dish washing systems that produce discharge water too high in temperature to maintain a functioning grease interceptor/trap. This temperature stabilization/cooling is achieved with Bio-Elements located inside the grease interceptor or grease trap, therefore representing an in-situ process.

Temperature stabilization/cooling is achieved by continuously measuring the effluents' temperature inside the FOG enclosure and by controlling air pumps to achieve the necessary cooling to restore the GT/GI designed function. Said air supplies the needed oxygen to maintain an aerobic biofilm suitable for bioremediation, maintain flow through the Bio-Elements, and also to cool the effluent, which is typically too high in temperature to enable effective bioremediation or function of a grease interceptor.

The present disclosure relates to biocarriers with high microbial loading and durability useful for waste treatment, waste treatment systems comprising the same, and methods of use thereof.

Embodiments of the present disclosure are directed towards a bioreactor, a floating bioremediation platform system, and a process for reducing sulfates, in surface water.

A carrier element (1; 10; 20) for growth of biofilm thereon is designed for free-flowing in liquid to be purified and has surfaces (3; 13) for biofilm growth which are protected from the abrasion from other carrier elements or surfaces in a container containing the liquid to be purified by ridges (4; 12) having a height corresponding to a desired thickness of a biofilm intended to grow on the protected surfaces (3; 13). The ratio between the surfaces (3; 13) for biofilm growth and the area of the ridges ranges from 1:1 to 1:20.

There is described a bioreactor comprising a perforated tube for inputting wastewater therein, a textured wall, such as a geotextile membrane, and an oxygenating unit comprising a pressurized air bubble diffuser. The wall is spirally installed around the perforated tube, defining a passageway fluidly connected to the perforated tube and along which the wastewater inputted in the perforated tube is forced to travel. The membrane is adapted for hosting aerobic bacteria at a surface thereof. The oxygenating unit is provided at a bottom of the passageway for oxygenating the passageway. The bioreactor can be included in a treatment apparatus comprising primary treatment chambers and a decantation chambers, forming a standalone unit which is compact and easy to install.
