Abstract: A machine to fast cook raw food-stuff including dry-goods such as pasta on demand. Cook time is user selectable and varies from less than one minute to 4 minutes. Higher cook times are user programmable and food type dependent. The separate boiler and cook chamber are sealed within an enclosure containing a heat transfer fluid. Porting enables the ingress, egress and transfer of raw and cooked food-stuff, liquid and vapor. Proprietary slide plate valves control food-stuff ingress and egress to the cook chamber. The upper slide plate valve assembly separates the cook chamber from the raw food ingress staging aperture. Rinse water and cooked food-stuff discharges into the drain pan containing and enclosing the food collection strainer through the lower slide plate valve assembly. Discharge of the cooked food product completes the cook cycle. The cooked food can then be deposited from the strainer onto a serving vessel.

Abstract: An improved process for sludge treatment includes anaerobic digestion followed by post-mesophilic aerobic and/or anoxic digestion. The first anaerobic step may be performed under either mesophilic or thermophilic conditions. The subsequent aerobic/anoxic digestion may be performed using either simultaneous, sequential or pulsed aerobic and anoxic conditions. An apparatus for performing the improved sludge treatment may be one digester for performing the anaerobic followed by aerobic/anoxic digestion. Alternatively, the system for performing the improved sludge treatment techniques may be at least two digest reactors.

Abstract: Enhanced wastewater treatment utilizing directed energy to promote degradation of sludge is disclosed. The directed energy is delivered in a stream circulating to and from an anaerobic digester. The directed energy incorporates mechanical shear energy, ultrasonic energy, and/or hydraulic shear energy. Characterization of odor potential is further disclosed involving the analyzing volatilized sulfur-containing species from dewatered sludge. The odor potential can be used to control operation of the wastewater treatment by controlling the directed energy and/or polymer dose.

Abstract: A wastewater treatment facility incorporates a trivalent cation salt to promote coagulation of flocculent material. The trivalent cation salt is typically added between a primary and a secondary treatment stage in the wastewater treatment facility. The trivalent cation is typically an aluminum salt. The amount of trivalent cation can be optimized by targeting a (M/D)/T ratio of less than about 1.0, where M is a monovalent cation equivalent concentration and D is a divalent cation equivalent concentration in the wastewater and T is a mass of the trivalent cation in the sludge. The amount of trivalent cation can also be optimized by targeting a M/T ratio of less than about 1.0, where M is a monovalent cation equivalent concentration in the wastewater and T is a mass of the trivalent cation in the sludge.

Abstract: A Method of treating sludge prior to dewatering by mixing with the sludge a cationic metal in the form of an iron or aluminum slat along with a cationic polymer. The addition of the iron or aluminum salt substantially reduces the amount of polymer required for acceptable dewatering, thusly significantly reducing the cost of the dewatering process. The method is enhanced by subjecting the prior digested sludge to mesophilic aeration prior to the cationic metal salt and polymer being added.
