A surface floating decanting equipment mounted on special knee-joints and controlled by forcing and venting a volume of air alternatively into a lower compartment of this equipment. No discharge valves are required. The decanter collection pipe is keep above the water level during the fill and react cycles to prevent any solids accumulation making it naturally solids-exclusive. This decanter concept has been developed and fully tested in Eco Process's test center. Also, a design tool was developed to make its design easy and reliable. A complete confidential report endorsed by our hydraulics engineer is available. This equipment was developed by Eco Process's research team through a project supported by the National Research Council of Canada (NRC). It is commercialized since 1997.
A submerged fixed decanter operated by initiating the siphon pipe to discharge using an airlift effect. The design is provided with solids-exclusive features. The operation principle has been fully tested in several conditions and the hydraulic performances are recorded. This decanter observed was developed in Eco Process's R&D center. A computer aided design was also developed for this decanter. A complete test report by our hydraulic engineer is available. This particular equipment was developed directly by the Eco Process's research team and is commercialized since 1988.
A surface floating decanting equipment mounted on vertical guides and controlled by a motorized discharge valve. The system uses flexible hose discharge and solids-exclusive air trap operation. The decanter discharge rate can be regulated when required. This decanter was developed in the Eco Process's R&D center and by the Eco Process's research team. This equipment is commercialized since 1999.
A surface decanter mechanically actuated by a drive motor system and a SS chain and sprocket assembly. This unit is kept above water level while the reactor is in the filling, reacting and settling modes making it a natural solids-exclusive decanter. This decanter has a perfect vertical travelling path and its discharge rate can be regulated when required. The decanter utilizes a flexible hose system to discharge the effluent into a commun header. The decanter was developed and tested in Eco Process's R&D center by the Eco Process's research team. A confidential report signed by our hydraulic engineer is available. This equipment is commercialized since 1992.
A surface decanter, mechanically actuated through a drive motor and a SS chain and sprocket assembly. It is mounted on knee-joints from the discharge pipe. An extended steel structure allows to pivot the calibrated collector pipe around the knee-joint piping. The discharge rate can be modulated as required. The HeadCanter™ concept was developed in the Eco Process's facility and by the Eco Process's team. This equipment was commercialized since 1998.
A fixed submerged decanter device consisting of a calibrated collector pipe in which a special rubber membrane is fitted and held in place. The unit is manufactured as an integrated large hydraulic valve that can be automatically opened or closed by forcing or venting a volume of air from a pressurized air source. The unit is again completely solid-exclusive when the membrane is inflated during the active mixed stages of the sequence. This decanter system was developed in Eco Process's R&D center and by the Eco Process's research team through a project supported by the National Research Council of Canada (NRC). It was commercialized since 1988.
A fixed submerged decanter consisting of a submersible pump mounted with adequate baffle and valve system. The concept is solid-exclusive. This arrangement was developed in the Eco Process's R&D center and by the Eco Process's research team and was commercialized since 1990.
A fixed submerged decanter consisting of a submerged or dry pit installed butterfly valve with SS extended stem and motorized actuator. Special baffles and supports are used to make it a solids-exclusive system. This decanter has been developed in Eco Process's R&D center and by the Eco Process's research team and was commercialized since 1998.
A fixed decanter consisting of a submerged weir assembly mounted across the entire width of the reactor and used to hold the new batch of wastewater in the reactor before allowing it to discharge freely across the whole width into an open discharge channel. The unit is designed to handle large city flows. The system utilizes a solid-exclusive principle of operation. This concept was developed directly by the Eco Process's research team and was commercialized since 1999.
UIDTM,
uniform influent distributor
A uniform influent distributor system consisting of an assembly of calibrated perforated pipe fed from one end only and capable of uniform distribution within 10% from the first orifice to the last one while the pressure drop is minimum. This concept allows to introduce the wastewater uniformly at the bottom of a SBR reactor at maximum velocity of 0.5 ft/second during mandatory fill-decant periods e.g. during high flow periods, particularly with domestic wastewater/municipal applications. This concept was developed and tested in the Eco Process's R&D center and a confidential report by our hydraulic engineer is available. The design model has been computerized. Two versions of this concept are also available. The Eco Process's research team in collaboration with the McGill University in Montreal developed this equipment which was commercialized since 1996.
USCTM, uniform sludge collector pipeTM
A uniform sludge collector pipe consisting of calibrated orifices pipe element with a withdrawal connection at one end only. This concept was developed by Eco Process and the hydraulic model is computerized. This equipment allows withdrawal of the excess sludge uniformly at a precise concentration so that the sludge age of the SBR reactors can be controlled automatically. A confidential test is available. The Eco Process's research team in collaboration with the McGill University in Montreal developed the equipment which is commercialized since 1996.
A hybrid aeration system consisting of a jet motive pump recirculating the mixed liquor through a manifold pipe equipped with calibrated venturi elements and an independent air blower system. The mixing manifold is assembled into an aeration header system through appropriate connections. The system can mix the content of the reactor without the assistance of air, forcing its biomass through anoxic and anaerobic conditions as may be required by specific treatment sequences (for nutrient removal for example). When aerobic environment is required, an air blower is started to provide pressurized aeration to the venturi system generating fine bubble aeration. The AirJetTM system was developed in the hydraulic laboratory of the University of Montreal by the Eco Process's research team. This development was supported by the National Research Council of Canada (NRC). It is commercialized since 1989.
A self-aspirating jet aeration system consisting of a jet motive pump connected to an injector type of venturi assembly in such a way to bring in atmospheric air and shear it into fine bubbles as the mixture is discharged from the equipment. This equipment is available in several versions to best fit every application. This equipment was developed in the hydraulic laboratory of the University of Montreal by the Eco Process's research team. The project was supported by the National Research Council of Canada. This equipment is commercialized since 1988.

A jet mixing system consisting of a series of venturi calibrated and aligned on a manifold pipe. The system comes with a jet pump connected to the jet manifold to recirculate the mixed liquor through all the venturi, keeping the biological solids of the SBR reactor in suspension. The system is used for nutrient removal in conjunction with air diffusers. The MixiJetTM system was developed by the Eco Process's research team. It is commercialized since 1990.
An extended coarse bubble diffuser concept developed for SBR and digester applications. The diffuser is mounted independently on air distributor pipe and is fed through a large orifice (one to two inches diameter). The feed-pipe only provides the pressure drop necessary for the uniform air distribution while the system is virtually clog-free. The concept has extra mixing power and allows to rapidly re-suspend settled or concentrated sludge (up to 8 %) from the SBR reactor or from the digester. The concept was developed by the Eco Process's research team. It is commercialized since 1988.
An exhausted flow control strategy developed into a software program to operate the process sequence in a viable manner to keep the biological treatment performance optimum while managing all flow variations. The program was developed by Eco Process and can accept and manage continuous or hourly peak flow periods reaching over 5 times the average flow condition of a plant. The BioLogTM program controls the operation of all motorized equipment of the SBR system and manages a complete series of alarms necesary to maintain the good performance of the biological treatment regardless of the flow variations during the day and night, or the attendance of the operator or of any equipment failure... including temporary power failure.
