Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel. A combustor vessel is configured to receive a solids component from the extrusion plate. A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

A UV disinfectant system may include a chamber having a wall that is transparent to a disinfecting radiation. Liquid may be flowed through the chamber for treatment by exposure to the radiation. The chamber may include a static mixer having vanes to impede laminar flow of the liquid during treatment. The vanes extend into the flow path of the liquid through the chamber. A gap is defined between the vanes and the transparent wall. A cabinet may house the chamber and radiation emitting bulbs. Blowers may be operably coupled to a temperature sensor and flow meter and positioned at a lower end and upper end of the cabinet to urge air out of the cabinet. The temperature sensor may include a thermocouple. The blowers may be variable speed blowers. The system may include a controller to control system operations. The controller may be remotely accessible to monitor or control operations.

A system includes a first separator configured to receive waste water, retain a first portion of the waste water, and separate the first portion of the waste water into a first vapor and a first solid material; and a second separator in fluid communication with the first separator, the second separator being configured to receive a second portion of the waste water from the first separator and to separate the second portion of the waste water into a second vapor and a second solid material, the second separator including a first condenser, a heating element, and a first electrocoagulation unit. Related apparatus, systems, techniques and articles are also described.

The disclosure provides automated methods and systems for optimized dosing of chemicals, such as coagulants, acids, and/or bases, in water treatment processes. The methods and systems of the disclosure can provide a coagulant dosing regimen that mitigates turbidity and organic contaminant content while maintaining effective floc precipitation, agglomeration, and settling without significant human intervention.

A fluid disinfecting system includes a fluid bath for soaking items to be disinfected, a fluid directing conduit, and a light source disposed adjacent the fluid directing conduit. The light source is operative to emit ultraviolet light into the fluid directing conduit, such that one or more cross sections of the fluid directing conduit are saturated with ultraviolet light. Any fluid passing through the fluid directing conduit is necessarily exposed to the ultraviolet light and thereby disinfected. The disinfected fluid is returned to the fluid bath, and the cycle continues.

A facility-based domestic wastewater treatment system equipped with modified toilets and a hypochlorous acid machine, neutralizing coliform bacteria from bodily excretions at the source. The treated batch content in the toilet is flushed to a secondary process tank equipped with a grinding pump, hypochlorous acid dispensing nozzles and solenoid valves. Toilet and other facility utilities wastewater are treated and discharged to a filtration system to be separated. The filtration system is capable of separating bacteria and other particulates up to or equal to a fineness of 0.01 microns. Separate storage tanks are used to store recovered and reclaimed water in conjunction with a slurry waste collection tank for solid waste disposal. A facility-based wastewater reclamation system utilizing Reverse Osmosis process to remove unwanted contaminants and dissolved solids producing potable water, some of which is further processed with UV, and Ozone treatment to be used as drinking and cooking water.

A system and method for controlling the accelerated remediation of the water of an aquatic facility using at least one sanitizer sensor, a pH sensor, a temperature sensor and a chlorine dioxide sensor all interfaced with a programmable controller that is programmed to implement a remediation cycle and configured to calculate a Ct value of the water chemical feed system. The programmable controller activates a chemical feed system to supply an acid, an oxidizer and a chlorite ion donor to a conduit to form chlorine dioxide that is supplied to the water until a desire Ct value is reached.

An electrochlorination system includes an electrolyzer fluidically connectable between a source of feed fluid and a product fluid outlet, and a sub-system configured to one of increase a pH of the feed fluid, or increase a ratio of monovalent to divalent ions in the feed fluid, upstream of the electrolyzer.

A plant and relative controlled production method of monochloramine; inside a reactor, at least a means or group creates and/or maintains a turbulent regime during the production reaction of monochloramine; at the end, at least a post-dosing means performs a further dosage of reagent directly in the concentrated solution of monochloramine produced directly in reactor or on the transfer piping or directly into the storage tank.

A separation unit for separating contaminants, such as oil, from water comprises at least one inlet section and a separation tank having an outlet for effluent, an outlet for liquid reject, and an outlet for gas. The inlet section comprises an inlet for influent, a gas injector for injecting gas into the influent, a turbulent mixing assembly for mixing the influent and the gas, and a diffuser for reducing a flow velocity of the mixed influent and gas. The separation unit is adapted to control a level of a gas-liquid interface in the tank by regulating leakage of gas using a liquid reject valve in the outlet for liquid reject and/or a gas reject valve in the outlet for gas. The separation unit maintains the level of the liquid interface below an entrance of the outlet for liquid reject during a normal mode of operation, and, during a fluid reject mode of operation, opens the liquid reject valve and raises the level of the liquid interface to be equal to or above the entrance of the outlet for liquid reject.
