A method for the efficient operation of a waste treatment apparatus comprising an anaerobic-aerobic sequencing batch reactors (SBR). The method comprises the synchronized transfer of waste between the reactors, for preventing unsafe buildup of pressure in the anaerobic reactor and reaching unsafe levels.

An aquaculture system including a fish tank, a floating media bioclarifier, and a mineralization tank. The mineralization tank includes a first influent inlet for receiving sludge having a first solids concentration from the bioclarifier, an effluent outlet for returning to the bioclarifier a fluid having a second solids concentration less than the first solids concentration, and a second influent inlet configured to receive influent from the fish tank which has bypassed the bioclarifier. A hydroponic system is configured to receive effluent from the bioclarifier.

A filtration apparatus and methods of installing, using, and retracting the same. A filtration apparatus includes a compression gland, a ball valve, and a filter pipe. A distal portion of the filter pipe has one or more filtration holes. The filtration apparatus may be installed in a process pipe and the distal portion of the filter pipe may be disposed within the process pipe. The filter pipe can be easily retracted from the process pipe without interruption of the industrial process. The filtration apparatus can be automatically cleaned by compressed air or water.

Methane is generated from animal waste by anaerobic digestion using bacteria. A screen separator removes suspended solids greater in size than a predetermined size ranging from about 50 .Math. to about 150 .Math.. An electrocoagulation unit electrochemically hydrolyses the waste, causing particles to settle out. A dissolved carbon air flotation has a CO.sub.2 bubbler for separating large particles from small particles by flotation. An anaerobic digester produces biogas. The digester has a biocurtain for growing the bacteria and a heat exchanger for heating the bacteria. The biocurtain surface is convoluted to retain the bacteria. A membrane module removes CO.sub.2. A knock out pot for removes droplets of water. A scrubber removes water vapor, particulates, and contaminant gas. A compressor boosts pressure. A gas chromatograph monitors the biogas composition. A flare skid lowers excess pressure for safety. Biogas is injected into a local pipeline system. A process control is used for controlling the anaerobic waste digestion system.

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.

Disclosed in the present invention are methods for the electrochemical generation of aqueous organic haloamine solutions from precursor solutions comprising at least one halide-containing salt, at least one organic amine component, and an acid additive. The described method allows for the production of aqueous organic haloamine solutions with compositions ranging from a single organic haloamine component to multiple organic haloamine components and multiple free halogen components and solutions with desired pH values.

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.

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 for solid household waste, disposals of meat processing plants, and water contaminated with oil and petroleum products. The method for treatment and disinfection of industrial wastewater includes flotation, electrocoagulation and filtration. The new is that the method also provides: mixing water with powder hydrophobic carbon-based sorbent with high absorbing capacity; filtration of a suspension of water and a carbon sorbent on a rubber-based hydrophobic sorbent; decomposition of saturated and unsaturated fat, oil, petroleum products and other organic substances accumulated on carbon and rubber sorbents; floatation in flow mode with the addition of hydrogen peroxide; recovery of the active substance in the presence of hydrogen peroxide; and its further reuse; electrocoagulation in flow mode with water saturation with oxygen and hydrogen, formed on indispensable carbon or metal electrodes, and on the active substance 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, filtering on activated carbon filter.

A method and an apparatus for maintaining a stable microbial community in a combined anaerobic-aerobic waste processing system. The system comprises cycling of waste activated sludge between reactors, thereby ensuring a healthy microbial community and an efficient waste decomposition.

A filtration device includes a continuous first unit including a first membrane that separates a liquid into first permeated and non-permeated liquids, a first adjuster that adjusts a flow rate of the first permeated liquid to be substantially constant, and a first liquid scale that detects a liquid amount, a second unit including a second membrane that separates another liquid into second permeated and non-permeated liquids, a second adjuster that adjusts a flow rate of the second permeated liquid to be substantially constant, and a second liquid scale that detects another liquid amount, a first controller that controls the liquid amount in the first storage tank based on measurement values from continuous two first units or from the continuous first and second units, and a second controller that controls the another liquid amount based on a measurement value from the second unit.
