The inventive control system can be built using different measurement units and control units. What units are used for building the control system depends on the wastewater treatment plant. This kind of system structure makes it possible to construct a control system that suits for a specific wastewater treatment plant. Therefore, the invention makes it possible to build a control system for different wastewater treatment plants, in such a way that the wastewater plant operates more efficiently.

The present invention relates to a filtering device for a water treatment system comprising a biological treatment device adapted to provide a sludge from wastewater or filtrated wastewater, and/or the biological treatment device being fluidic connectable to or in fluidic connection with the filtering device for receiving filtrated wastewater from the filtering device and for delivering sludge to the filtering device. The filtering device is a cake filtration device comprising a fluid penetrable support structure and the support structure is provided as one or more tubular elements having a filtration cake provided on the inside of the fluid penetrable support structure. The filtering has device an inlet being connectable to receive liquid to be filtered so that the flux of liquid to be filtered is from the inside of the support structure, through the filtration cake and to the outside of the support structure thereby providing a filtrate, an outlet for outletting liquid from the interior of the tubular element, and a filtrate outlet for outletting filtrate from the filtering device. The filtration cake is being provided by deposition of solids from the sludge formed in the biological treatment device.

A system and a method comprises a chamber configured to receive a flow of a wastewater mixture from an input. A first baffle wall forms a first channel within the chamber. The wastewater mixture flows from an input to an output of the first channel. A second baffle wall forms a second channel and a third channel within the chamber. The wastewater mixture flows from the output of the first channel to an input of the second channel to an output of the second channel to an input of the third channel to an output of the third channel. The output of the third channel is configured to direct the flow to an output from the first chamber.

A hybrid membrane aerated biofilm reactor (MABR) and activated sludge (AS) system and process are described herein. At least a portion of the AS system includes aerobic mixed liquor, for example in an aerobic tank or zone downstream of a tank or zone containing membrane aerated biofilm modules. The flow of air to the membrane aerated biofilm is modulated considering the ammonia loading rate to the system or to the aerobic mixed liquor, for example according to a diurnal cycle. For example, air flow to the membrane supported biofilm can be below an average or initial air flow rate during a period of low ammonia loading. Air flow to the aerobic mixed liquor may remain essentially constants during the same period. Optionally, mixed liquor around the membrane aerated biofilm modules may be aerated during a period of high ammonia loading.

A sewage treatment chlorinator for use at a site not connected to a municipal sewer system and system and method for use of the same are disclosed. In one embodiment of the sewage treatment chlorinator, a housing includes an external conduit coupled in a t-connection to a flow tube. An inner canister is sized to be selectively inserted and removed from the external conduit and includes a perforated end cap having a flow deck sized to suspend a chlorine tablet within a contact chamber of the flow tube. The flow tube receives effluent form an aerobic tank and discharge treated effluent to a post-treatment tank. At least a portion of the discharge from the flow tube is gravity-based discharge into the post-treatment tank.

Disclosed is a modified activated sludge-based two-compartment treatment method for processing nitrate-contaminated drinking water. Raw water is firstly sent to a first TiO.sub.2-modified denitrifying activated sludge bioreactor (2), wherein organic carbon source is added in a controlled amount, and nitrate is partly reduced with nitrite being accumulated. Then, the effluent from the first bioreactor is sent to a second TiO.sub.2-modified denitrifying activated sludge bioreactor (3), wherein organic carbon source and hydrogen gas are supplemented, and remaining nitrate and accumulated nitrite are reduced to nitrogen gas. The denitrified effluent from the second bioreactor is sent to a settling tank (4), and TiO.sub.2-containing precipitates collected from the settling tank receive sequential alkaline and acidic treatment before being injected into the first bioreactor (2) for TiO.sub.2 recycling. The effluent from the settling tank (4), after having been subjected to ozone disinfection and activated carbon filtration, has suitable pH and bicarbonate alkalinity, and the concentrations of nitrate, nitrite and water soluble organics meet the safety standard for drinking water. Also disclosed is a modified activated sludge-based two-compartment treatment device for processing nitrate-contaminated drinking water.

A method of providing, maintaining and using a youthful added microbe population for the treatment of wastewater. A method of providing green sustainable microbiology net zero carbon solution to waste water and waste material treatment using biofermentation to treat the waste water and waste material with aa treatment containing biofermented microbes.

A system for digesting biodigestible feed that preferably includes the steps of comminuting the feed, introducing feed, an oxygen-containing gas, an accelerant, and bacteria into a digestion zone, the bacteria being suitable for digesting the feed under aerobic, anaerobic, and anoxic conditions. The contents of the digestion zone can be changed from aerobic operation to either anoxic or anaerobic operation, or vice versa, without changing the bacteria in the digestion zone.

The present invention relates to a method and a device for controlling pollutants in basin water resources cycling utilization in agricultural activity areas. The method includes: providing an acidification tank, an aeration tank and a multi-media constructed wetland connected in sequence, which are 4˜10 m far from basin revetment, feeding basin water into the constructed wetland, adsorbing or degrading heavy metals and organic pollutants by the constructed wetland, and then transporting the treated basin water to the agricultural activity areas. The present invention effectively controls the content of heavy metals that will enter the agricultural activity areas, fundamentally reduces the content of heavy metals in the crops, promotes the growth of the crops, maintains sustainable and healthy development of agriculture, and therefore guarantees human health and safety.
