A two-step process for recovering useable solids from food processing wastewater and for significantly reducing the pollutants, chemical, bacterial, and viral load. The first step is the addition of pretreatment chemicals such as metal-based coagulant, pH adjuster, oxidant or a combination thereof. The second step is pumping the chemically pretreated wastewater into a foam fractionation system where a gas is introduced into the chemically treated wastewater to create a rising foam that captures and remove solid materials from the remaining wastewater effluent. The solids are recovered for additional post-processing and the effluent is discharged for post-processing or to existing bodies of water.

A universal chemical processor (UCP) including a reactor vessel having a central longitudinal axis and main chamber comprises a first inlet port for a main feedstock, a second inlet port for a fluidizing medium and a third inlet port for one or more reactants. The UCP also includes a reactive radioactive chemical processor (R.sup.2CP) that contains a radioactive element positioned extending along the longitudinal axis in the main chamber. In operation, a fluidized bed can be supported in the main chamber when a fluidizing medium and feedstock are supplied to the main chamber through the first and second inlet ports and the radioactive element of the R.sup.2CP emits ionizing radiation that is capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing any organic materials within a radiation zone.

The invention relates to the methods for sewage treatment contaminated by mechanical impurities, fats, proteins and other organic and inorganic compounds, and can be used for purification and water disinfection contaminated by heavy and radioactive metals, saturated or unsaturated fats, filtrate from landfills, meat processing plants, and/or oil and petroleum. The method includes flotation, electrocoagulation and filtration, and provides: mixing water with carbon-based sorbent; filtration of water and carbon sorbent on rubber-based hydrophobic sorbent; decomposition of organic substances accumulated on carbon and rubber sorbents; floatation with hydrogen peroxide; recovery active substance in hydrogen peroxide; reuse thereof; electrocoagulation with water saturation with oxygen and hydrogen, formed on indispensable carbon or metal electrodes based on the of aluminum, titanium, sodium, tin, copper, and other metals; water disinfection by electro-cavitation; generation of active substance based on the iron and titanium atoms; water filtration on the precoat filter; and filtering on activated carbon filter.

A method of treating contaminated water that has ferrous ions and at least one additional mineral in solution includes the steps of: adding a sufficient quantity of a caustic agent to the contaminated water to achieve a basic pH, and adding oxygen to the contaminated water to achieve a molar ratio of oxygen to ferrous iron of at least 1:10. The pH and the oxygen concentration are sufficient to produce ferrous hydroxide (Fe(OH).sub.2) from ferrous ions and ferric hydroxide (Fe(OH).sub.3) from the ferrous hydroxide while limiting colloidal iron formation, at least the ferric hydroxide forming a precipitate. The precipitate is separated from the contaminated water.

Disclosed is a device for selective oxidation of macromolecular organic pollutants using free radicals produced in a heterogeneous Fenton reaction. The device includes a heterogeneous Fenton reaction unit and an electrochemical cell. The heterogeneous Fenton reaction unit includes a reactor and an anion exchange membrane. The anion exchange membrane is disposed in the reactor and separates the reactor into a first chamber and a second chamber. The first chamber is filled with a catalyst and the wastewater to be treated; and the second chamber is filled with a dielectric material. The electrochemical cell is configured to supply an electric field to the reactor, so that organic acids generated by a heterogeneous Fenton reaction move from the first chamber into the second chamber.

A non-transitory computer-readable medium including instruction that instruct a controller to perform a method of controlling addition of a treating agent into a wastewater stream collection system. A controller for a system configured to treat odor and control corrosion in a wastewater stream collection system that is operatively connectable to a metering valve for administering a treating agent to a wastewater stream collection system.

A method for removing organic pollutants from water bodies by activating persulfate with nutrient-enhanced soybean sprout-based biochar involves a method for removing organic pollutants from water bodies by activating persulfate with biochar. The invention is intended to solve the technical problems that existing biochar materials show poor catalytic activity when used for activating persulfate and requires the addition of a large amount of modifiers, which easily leads to secondary pollution to the environment, and the existing biochar materials are susceptible to interference from halogen ions, oxoanions, and natural organic matters in a persulfate system. The raw material of a catalyst used in the invention is soybean, and has an activation process mainly based on non-radical activation, exhibiting high reaction rate and saving persulfate. With the addition of 0.2 g/L catalyst and 0.5 mM potassium persulfate, the degradation efficiency against 10 mg/L phenol can reach 100% within 10 min.

A method for differentially lysing a liquid sample or target material using an augmented oxidizing agent (AOA), which includes a quantity of electronically modified oxygen derivatives (EMODs). The method reduces or eliminates total dissolved solids (TDS), total suspended solids (TSS), Biologic Oxygen Demand (BOD), microbial concentration, biofilms and other content in the liquid target material known or suspected to contain animal fluids, blood and blood cells and suspected or known to contain eukaryotic cells, microbial cells, bacteria, viruses, spores, fungi, prions, organic matter, minerals, proteins or associated structures. The BOD, TDS and TSS can be lowered or eliminated as desired. This action is directly proportional to the quantity of EMODs in the AOS applied to the liquid target material.
