A water treatment system is disclosed having an electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

A method for electrochemical treatment of water is provided. The method includes providing a flow-through reactor including a cathode and an anode, wherein the anode includes about 80 weight percent or greater of a sub-stoichiometric titanium oxide. The method further includes applying power to the cathode and the anode, passing a solution including water and a metal chloride through the flow-through reactor, and withdrawing the purified water.

A water treatment apparatus includes a water receiver configured to receive an input of water; and an installation mechanism configured to include one or more slots in which a module for water treatment is installable. Among a plurality of types of modules available to be selected in accordance with a use of water treatment, at least one module includes a filter as a component, and the water treatment apparatus is configured to provide a water treatment function corresponding to the module to the water received at the water receiver by installing the module in one of the one or more slots.

An embodiment provides a method of forecasting water quality deterioration in a water distribution system, including: receiving, at an electronic device, a data set comprising measured values of a plurality of components within the water distribution system; determining, based upon algorithmic analysis of the measured values, a water quality index; and providing, based on the determined water quality index, a recommendation to mitigate water quality deterioration in the water distribution system.

An apparatus for electrochemical activation may include an intake for an aqueous salt solution, a flow conduit structured to direct the aqueous salt solution through the apparatus comprising at least two electrodes spaced apart from each other within the flow conduit; a control module electrically coupled to the at least two electrodes, wherein the control module controls application of electricity to the at least two electrodes; and a sensor structured to measure a parameter of the aqueous salt solution and provide feedback to the control module to control an aspect of operation of the apparatus.

A water quality and flow monitoring and control apparatus, method and system installed at an end user location and being capable of monitoring one or more of the following water quality parameters: microorganisms (including E. coli), mineral or other ion concentration, pH, temperature, and turbidity. The system also has a water meter that detects the flow of water and has a valve to shut the flow of water off upon detecting a fault condition such as a leak.

A system and method for conditioning water is provided. A fluid flow sensor senses a flow of untreated discharge water passing through a water discharge drain line. The sensor generates one of a first sensor signal indicating a flow of the untreated discharge water and a second sensor signal indicating an absence of the flow of the untreated discharge water. A water conditioning controller transmits a first actuation signal to a conditioning agent pump when the first sensor signal is received, wherein a portion of a conditioning agent residing in a conditioning agent reservoir is pumped into the water discharge drain line to mix with the flow of untreated discharge water, and transmits a second actuation signal to the conditioning agent pump when the second sensor signal is received so that the portion of the conditioning agent is not pumped from the conditioning agent reservoir.

According to one or more embodiments, sulfate ions may be removed from seawater to form an injection fluid by a method including passing the seawater and formation water to a mixing tank. The seawater may comprise sulfate ions. The formation water may comprise barium ions. The seawater and formation water may be passed to the mixing tank in a ratio determined by a computerized geochemical model. The method may further include mixing the seawater and formation water to form a mixed fluid and passing the mixed fluid to a clarifier, where a barium sulfate precipitate may be formed and at least a portion of the barium sulfate precipitate may be separated from the mixed fluid. The method may further include passing the mixed fluid to a microfiltration system, where at least a portion of the barium sulfate precipitate may be removed from the mixed fluid to form an injection fluid.

A method of maintaining a body of water in a usable condition through a comparative measurements of total chlorine and free chlorine in the body of water to determine if a synergistic chemical combination exists within the body of water that can effect the amount of chlorine to add to the body of water.
