The sanitizer includes an elongated semi-cylindrical tank that houses heated process water and a close-fitting auger to move food products from the inlet end of the tank to the outlet end. Heated process water at a temperature sufficient to sanitize the food product is introduced into the tank at the outlet end of the tank to flow through the tank counter to the direction of flow of the food product. A recirculation and filter system filters out the particulates in the process water. A hood assembly is positioned over the tank to contain the air borne moisture generated during the sanitizing process and route the steam away from the tank. A control system controls the operation of the sanitizer, including, for example, the speed of the auger, the volume of process water in the tank, and the temperature of the process water in the tank.

A mixed fluid separator apparatus includes an overload protection chamber that prevents a large and sudden influx of oil from fouling a coalescing separator. To prevent sudden influx of a large concentration of oil from overwhelming the coalescing separator, a separate overload protection chamber is connected to a main coalescing separator apparatus. The overload protection chamber includes a water drain (majority water with some oil) to the main coalescing separator apparatus and an oil overflow (majority oil with some water) to drain excess oil when necessary to prevent overfilling of the coalescing separator apparatus. The overload protection chamber functions to rapidly separate and remove heavy concentrations of oil, protecting the main coalescing separator apparatus.

A membrane photobioreactor for treating nitrogen and phosphorus that are out of limits in a biogas slurry and treating method thereof, relating to biogas slurry treatment. The membrane photobioreactor for treating nitrogen and phosphorus that are out of limits in a biogas slurry is provided with a biogas slurry storage tank, peristaltic pumps, a microalgae cultivating tank, an air pump, a membrane photobioreactor and a hollow fiber membrane. The biogas slurry containing nitrogen and phosphorus that are out of limits is stored in the biogas slurry storage tank, and is driven by a first peristaltic pump to circularly flow in a silicone pipe; a microalgae solution is cultivated under illumination in the microalgae cultivating tank, and is driven by a second peristaltic pump to circularly flow in a silicone pipe, air is fed into the microalgae cultivating tank through the air pump, the biogas slurry and the microalgae solution are converged in the membrane photobioreactor, and the biogas slurry circularly flows inside the hollow fiber membrane pipe and the microalgae solution circularly flows outside the hollow fiber membrane pipe, the two being in a cross flow; and the nitrogen and phosphorus that are out of limits in the biogas slurry penetrate from the inside of the hollow fiber membrane and are absorbed by the microalgae solution outside the membrane, and after cyclical cultivation, nitrogen and phosphorus that are out of limits in the biogas slurry are absorbed, and the discharge standards are achieved.

The invention relates to a spiral pump and a device for treating water comprising this spiral pump, and associated method. The spiral pump comprises: a housing provided with an inlet for water; and a pump body which is accommodated in the housing and rotatable around an axis, wherein the pump body comprises at least one spiral channel, wherein a first outer end of the at least one spiral channel is located on an outer side of the pump body and forms an entrance opening for alternately taking in water and air through rotation of the pump body in the housing, and a second outer end of the at least one spiral channel debouches into an outlet close to the axis, wherein the housing is embodied as pressure chamber and wherein the at least one channel is provided with an increasing diameter from the entrance openings in the direction of the axis.

A single step pretreatment of wastewater or recreational water is provided comprising treatment with nanocomposites consisting of an anchoring particle such as a clay mineral and one or more polymers.

The present invention relates to a process for purification of wastewater. In particular, the present invention pertains to an improved process for purification of wastewater by employing anolyte as an additive.

A substance is treated using a device having: (a) a volute or cyclone head, (b) a throat connected to the volute or cyclone head, (c) a parabolic reflector connected to the throat, (d) a first wave energy source comprising a first electrode within the volute or cyclone head that extends through the outlet into the opening of the throat along the central axis, and a second electrode extending into the parabolic reflector and spaced apart and axially aligned with first electrode, and (e) a second wave energy source disposed inside the throat, embedded within the throat or disposed around the throat. The substance is directed to the inlet of the volute or cyclone head and irradiated with one or more wave energies produced by the first and second wave energy sources as the substance passes through the device.

A multi stage process for the separation of bio-components from grease trap waste and animal waste materials is disclosed. Targeted polymers are added to the source and separated streams prior to passing the streams through separation equipment including a rotary screen, one or more presses, a dissolved air floatation device and a clarifier in which the waste stream is separated into a stream containing predominantly oil, grease and protein, a stream containing predominantly water and a stream that predominantly contains fibers.

Disclosed herein are microbiome-based compositions for reducing and/or eliminating target compounds from water within recycled aquaculture systems. This disclosure also relates to methods for preparing dynamic microbiome-based compositions, and methods for deploying the dynamic microbiome-based compositions into recirculating aquaculture water systems.

The present invention relates to the treatment of a wastewater stream that is generated from animal processing such as the processing of chicken, beef or pork. More particularly, the present invention relates to the separation of usable protein from an animal processing wastewater stream using a density modifier and a modification of the protein phase density to enhance lipid fat phase separation from protein solids.
