Patent
Environmental Dynamics International Inc. | Date: 2014-06-02

A wastewater treatment system is provided having a reactor, first and second bio media and an aeration system. The first bio medium is located proximate an inlet end of the reactor and extends vertically between a top water level and the reactors floor. The second bio medium is located proximate an outlet end of the reactor and extends vertically between a bottom water level and the reactors floor. The media are adapted for retaining solids within the reactor as clarified water is withdrawn after treatment. The first bio media is further adapted to act as a baffle thereby causing wastewater to flow generally uniformly into a primary reactor zone. The aeration system includes a plurality of diffusers, some of which may be located adjacent or underneath the bio media and are adapted for promoting the shaking the bio media when activated in order dislodge excessive biomass therefrom.

A single-layer diffuser membrane constructed of first and second compounds. The first compound has structural and flexibility properties suitable for applying air to wastewater through a plurality of perforations formed through the membrane and the second compound is suitable for inhibiting fouling of the membrane. The first compound may comprise polyurethane and the second compound may comprise polytetrafluoroethylene. The concentration of the second compound within the membrane may be between about 3.0 vol. % and 20.0 vol. %. The second compound may be dispersed adjacent the perforations to inhibit fouling of the perforations. Another aspect of the present invention relates to the method for constructing the membrane. Upon the mixing of the first and second compounds, the mixed composition may be formed into a membrane through, for example, an extrusion process or a molding process. Perforations may be created either during or after the forming of the membrane.

A wastewater treatment system and method are provided for preventing or reducing ammonia rebound during periods of warming weather. The system may be operated in first and second modes of operation. During the first mode of operation, wastewater may pass directly from a reactor to a partial mix cell and then to a polishing cell. During the second mode of operation, which typically occurs during a springtime warmup period, wastewater is retained within the partial mix cell until sludge and biosolids therein are substantially digested, while wastewater exiting the reactor is temporarily directed to the polishing cell, thereby bypassing the partial mix cell. Upon digestion and stabilization of the sludge and biosolids in the partial mix cell, the system may return to the first mode of operation. Sludge and biosolids may optionally be removed from the reactor during the first and second modes of operation.


Patent

A system and method for treating wastewater in a reactor of the system at or below a predetermined flow rate and at or above a predetermined temperature is provided. Incoming wastewater in excess of the predetermined flow rate is directed to an equalization basin for storage. Wastewater stored in the equalization basin is directed to the reactor when (a) the temperature of such stored wastewater is equal to or greater than the predetermined temperature and (b) wastewater is received by the system at a rate less than the predetermined flow rate. The method also involves the step of repurposing a lagoon basin of an existing lagoon system to function as the equalization basin. The system may further include an integrated control system for directing wastewater stored in the equalization basin to the reactor when predetermined conditions are met.
