As an example embodiment, a system may detect water flow in a well water system and may responsively trigger a pump to inject a chlorinating substance into untreated water from the well. Further, the system may include a contact reservoir that allows the water and the chlorinating substance to combine. In this way, the chlorinating substance is drawn only when needed, but is given the opportunity to achieve time in solution with the untreated water. As a result, bacteria in untreated water may be dispatched, while other organic substances in the untreated water are given the opportunity to settle to the bottom of the contact reservoir. A static mixer may be used to mix the chlorinating substance and the untreated water prior to entering the contact reservoir and/or while in the contact reservoir.

This invention relates to processes for the removal of phosphorous from aqueous waste streams comprising phosphorus-containing compounds produced in the manufacture of glyphosate, in order to meet and typically exceed environmental regulations. More particularly, various embodiments of the present invention relate to the removal of phosphorous-containing compounds utilizing biological treatment system(s), oxidizing agent(s), and/or precipitant(s). The processes of the invention are also applicable to the removal of phosphorous compounds from phosphorous-containing waste streams other than those waste streams resulting from the manufacture of glyphosate.

The present invention provides an agent dispenser for use in introducing an agent into a fluid where the agent is miscible with such fluid. The agent dispenser comprises a hollow casing constructed of a material having a coefficient of cubical expansion that differs from the coefficient of cubical expansion of the fluid. At least one opening is provided in the hollow casing for permitting the flow of the fluid to and from the interior of the hollow casing. The opening is provided with a tube sealed in the opening, one end of the tube being contained within the hollow casing and the second end of the tube being exterior to the hollow casing for communication with the surrounding fluid. The second end of the tube is provided with a filter membrane having a defined pore size to prevent any debris which may be present in the fluid from blocking the second end or entering the hollow casing. The dispenser contains the agent and the agent is introduced into the fluid through fluid drawn into and expelled from said dispenser as a result of variations in the internal pressure of the dispenser resulting from thermal expansion and contraction of the dispenser and its contents caused by variations in the temperature of the fluid surrounding the dispenser.

Techniques and systems for neutralizing discharge waters from ballast and/or cooling water biocidal treatment and disinfection systems are provided. The systems utilize oxidation reduction potential control to regulate the dechlorination of a biocidal agent to allowable discharge levels in ship buoyancy systems and ship cooling water systems.

Example aspects of a remote-operated flushing system and a method of operating a flushing system are disclosed. The remote-operated flushing system can comprise a fluid routing assembly comprising a valve, the valve configurable in an open configuration, wherein fluid is permitted to flow through the fluid routing assembly, and a closed configuration, wherein the fluid is prohibited from flowing through the fluid routing assembly; a control device configured to actuate the valve between the open configuration and closed configuration; a remote operation device wirelessly connected to the control device and configured to remotely operate the control device to control the actuation of the valve between the open configuration and closed configuration; and a sensor configured to detect a fluid property of the fluid within the fluid routing assembly, wherein the control device is configured to wirelessly send a signal representative of the fluid property detected by the sensor.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

A system and method for controlling the accelerated remediation of aquatic facilities 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, the sensors being in fluid contact with water of the aquatic facility, and the programmable controller is interfaced with a chemical feed system for supplying chlorine dioxide to the water.

A process for purifying washing waters of a production plant of the cosmetics sector includes subjecting the washing waters to an ultrafiltration treatment that produces an ultrafiltration concentrate and ultrafiltration water, and subjecting ultrafiltration water to a biological treatment with separation of sludges to be disposed of or further treated and treated water to be disposed of or to undergo subsequent treatments.

A method for treating wastewater involves electrolyzing a stream of seawater and wastewater mix within one or more electrolytic cells mounted outside a batch tank. The electrolyzed stream is piped to a quelling chamber which is mounted above the batch tank. A diluted polymer solution is injected at upstream of an in-line mixer piping into the quelling chamber substantially concurrently with the electrolyzed stream. The polymer solution and the electrolyzed stream are dispersed as a fine shower over residual seawater and wastewater in the batch tank. The polymer solution facilitates flocculation of the suspended solid particles and creates a distinct buoyant layer of flocculated solid particles attached with micro bubbles. A substantially clarified effluent is separated from the flocculated layer and neutralized prior to discharge. The flocculated layer is pumped from the batch tank to a dewatering system where entrained solids are compacted to a desired level. A centrate generated during the solids/sludge dewatering step is recirculated to the batch tank prior to addition of seawater during a subsequent treatment cycle as a supplement to the seawater.

Techniques and systems for neutralizing discharge waters from ballast and/or cooling water biocidal treatment and disinfection systems are provided. The systems utilize, inter alia, oxidation reduction potential control to regulate the dechlorination of an electrocatalytically generated biocidal agent to allowable discharge levels in ship buoyancy systems and ship cooling water systems
