This invention is a novel method to thermally process wet WWTP sludges, including biosolids, so that they can be classified. Wet biosolids or other WWTP sludges are passed through the heating zones of one or more solar thermal systems so that the sludges are heated to a target temperature to meet the requirements for U.S. Environmental Protection Agency classification. Various catalysts are provided before the sludges enter the heating zone and within the heating zone to optimize the treatment of the sludges.

A water treatment system, such as a water softening system, having a water treatment tank with at least one distributor plate mounted inside to support filter media and/or ion exchange resin. The water treatment system is designed to treat hard water with a packed ion-exchange filter media and has a distributor plate design for facilitating the ion-exchange within a water softener resin bed, as well as facilitating the regeneration of the resin bed. The distributor plate presents cavities to the topside for entrapping filter media, and the cavities have narrow slits located at the base for allowing fluid to pass. A method for assembling the water treatment tank and supporting inserted distributor plate is shown. The distributor plate rest on and is supported by a domed-shaped structure that can be placed in the bottom portion of the water treatment vessel.

A water softener apparatus comprising a housing having a chamber for accommodating at least one compressed salt block having an elongated block form, the configuration accommodating the compressed salt block within the chamber with its longitudinal axis in a vertical orientation. The water softener apparatus includes a manually detachable front cover enclosing the chamber and a non-touch salt level indicator device arranged in or on the front cover of the housing above the chamber to determine a salt level from an upper end face of the compressed salt block accommodated in the chamber, the non-touch salt level indicator device determining the salt level from the upper end face of the compressed salt block through a wall of the front cover of the housing. The non-touch salt level indicator device is a battery powered device and the water softener apparatus is a non-electric powered water softener apparatus.

An advanced hydrodynamic cavitation system includes a housing, a first stator with angled ridges, a second stator that is circular with angled ridges, a rotor having rotor blades housed within the second stator, and a driveshaft, and is configured to work with a motor, a pump, and oxidizing agents such as hydrogen peroxide or ozone to form free radicals. Hydrodynamic cavitation occurs (1) on the leading edge of the rotor blades; (2) in the constriction between the rotor blades, depending on the design; (3) in the gap between the first stator and the rotor blades; and (4) in the gap between the second stator and the rotor blades. The four cavitation regions may coalesce to become a steady-state supercavitation cloud that removes unwanted, toxic or contaminated organic and inorganic compounds, specifically with the ability to treat and decontaminate sludge, wastewater, ballast water, drinking water, harmful algal blooms, and biomedical waste.

A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

An improved system and method for extracting volatile organic compounds (VOCs) such as ammonia from leachate water. Uses specialized pressurization of leachate water to extract VOCs which may then be recaptured in more highly concentrated water to reduce overall volume of contaminated water.

A media tank includes a housing having a first housing portion coupled to a second housing portion at an interface between the first and second housing portions, the first and second housing portions collectively defining an interior volume of the housing, and a divider positioned within the interior volume of the housing at the interface between the first and second housing portions to separate the interior volume into a first chamber at least partially defined by the first housing portion and the divider and a second chamber at least partially defined by the second housing portion and the divider. The first housing portion is coupled to the second housing portion via a friction weld at the interface. An annular gap is provided between the divider and the first housing portion. Flash from the friction weld is received within the annular gap.

A system and method for the microbiological purification of a liquid. The system includes a high-efficiency plate heat exchanger connected to a coil recirculation chamber via a high-efficiency infrared electric liquid-heater. The liquid enters the system at an ambient temperature, the temperature is raised by the heater and maintained in the chamber via recirculation by a pump. An electronic controller redirects the liquid through the exchanger to cool it and supply to a plumbed outlet. In combination, the system can be used to monitor and control various temperatures, pressures, flow rates, and heat exchanges in order to purify the liquid. The method includes steps to produce, install, implement, and use the liquid purification system to eliminate, neutralize, kill, or otherwise exclude/minimize biological organisms and contamination from the liquid.

An electrochemical oxidation reactor includes rotatable electrodes inside a reactor vessel. The electrodes are mounted to support plates, which in turn are mounted on shafts. The plates are attached to each other in a spaced relationship so that a gap is formed therebetween. The plates are each electrically insulated from each other. The electrodes are mounted to the inside surfaces of these plates, inside the gap. The gap is sized to receive liquid to be treated so that liquid located within the gap will react with the electrodes. An electrical charge is applied to each shaft so that a dielectric is formed across the gap within the fluid located in the gap. According to a first embodiment, an electrochemical reactor includes containing two spaced electrode support plates. According to another embodiment, an electrochemical reactor includes several spaced electrode support plates.

A waste liquid treating device includes a holding section that holds an adhesion plate, a vertically moving mechanism that moves the holding section vertically, and a peeling mechanism that peels off water-containing swarf from the adhesion plate held by the holding section. The peeling mechanism includes two air nozzles extending in parallel to each other in a horizontal direction with a spacing therebetween and including jet ports formed to face each other, a valve disposed in a piping providing communication between the two air nozzles and an air source, and a control unit that performs control of opening and closing of the valve and control of the vertically moving mechanism for moving the adhesion plate in the vertical direction in the spacing between the two air nozzles.
