摘要： The present invention relates to a water remediation system and accompanying method. The method comprises remediation by reducing the concentration of nutrients in the water and dosing the water with metal ions. It has been found that through a combination of reducing nutrients present in the water and treating with metal ions, the requirement to treat with high chemical dosages is removed.

摘要： Systems and methods that enable the responsive treatment of a body of water with an aqueous halogen solution whose composition can be varied as a result of input from sensors monitoring the water being treated. Various sensors are immersed in the water so that the physical, chemical, and microbiological properties of a body of water being treated can be measured. Information from these sensors is used to produce aqueous halogen solutions of varying composition which are then injected into the body of water being monitored for the purposes of ensuring the body of water being treated is being effectively disinfected.

摘要： Provided is a process for the environmental-friendly treatment of sulfate-containing wastewater. The acidic, sulfate-containing wastewater is treated in a sulfate reducing bioreactor with influent and effluent looped through to the cathode compartment of an electrochemical cell. The electrochemical cell stabilizes the pH in the bioreactor by the in-situ production of base in the cathode compartment. Additionally, hydrogen is produced which is used in the bioreactor as electron donor for the sulfate reduction. The middle compartment of the electrochemical cell contains a sulfide rich aqueous solution in which the extracted cations are displaced by protons from the anode compartment. This results in the acidification of the sulfide rich solution, which is beneficial for the extraction of sulfides as H2S. This H2S can be used for the precipitation of metals in the beginning of the process, forming another loop.

摘要： A water purification module includes a fluid path and a control unit. The flow path includes a cationic resin cartridge, an anionic resin cartridge in fluid communication with the cationic resin cartridge, and at least one bypass fluid path arranged to bypass one of the cationic resin cartridge and the anionic resin cartridge, while allowing water to flow to the other of the cationic resin cartridge and the anionic resin cartridge. The flow path also includes a valve arrangement comprising one or more valves configured to selectively direct water to the at least one bypass fluid path. The control unit is configured to control the valve arrangement to direct water to the at least one bypass fluid path based on a production mode of the water purification module.
