The invention pertains to a method of optimizing the chemical precipitations process in water treatment plants and waste water treatment plants using an aluminum based coagulant, wherein the optimization, which comprises the degree of contamination of the Clear water phase after precipitation and sludge separation, cost of operation and sludge production, is obtained by in situ regulation, of precipitation pH, amount of coagulant that is used in the precipitation process and the basicity of the coagulant, based at least on online measurement of degree of contamination, pH, flow and temperature of incoming untreated water and/or in the clear water phase, characterized in that the basicity of the coagulant is regulated by adding in situ, to a stock solution of polymerized aluminum based coagulant (A), acid or a solution of an aluminum based coagulant (B) having a lower basicity than the polymerized aluminum based coagulant (A) in the stock solution.

A water treatment system is provided. The system includes a container holding a reactant liquid within the container. The system further includes an electrode capsule removably retained within the container and submerged in the reactant liquid. The electrode capsule operates to generate reactant gas by operating within the reactant liquid. The system includes a cap releasably coupled to an opening of the container. The cap includes a nozzle that allows flow of reactant gas out of the container to treat an amount of water. The use of the system operates to treat water for particular applications and controlling pH level range and/or alkalinity for each particular application.

A system and method for treatment of wastewater, in which the system includes a blackwater reactor configured to receive a stream of blackwater influent, to contain the blackwater therein during treatment of the blackwater, to facilitate recovery of methane and nutrient precipitates therefrom, and to output partially treated blackwater, and a greywater reactor configured to receive a stream of greywater influent and the partially treated blackwater output from the blackwater reactor, to contain the greywater and the partially treated blackwater therein during greywater treatment, and to output greywater treatment discharge. The process includes inputting a stream of blackwater into the blackwater reactor; treating the blackwater in the blackwater reactor with an anaerobic digestion process; controlling a pH level of the blackwater within the blackwater reactor; recovering nutrient precipitates from the blackwater reactor, optionally independent of chemical additives; and recovering methane from the blackwater reactor.

Embodiments of the invention provide a method, system and computer program product for automated sampling, testing and treating large water basins. In an embodiment of the invention, the method includes storing a plurality of locations of a water basin, where each location includes at least one chemical delivery outlet. The method further includes monitoring water quality for each of the plurality of locations and mapping a water quality value to each of the locations. The method even further includes responsive to the water quality value failing to meet a threshold value in one of the locations, automatically determining an amount of chemical based on the water quality value and delivering the amount of chemical only to the one of the locations through its corresponding chemical delivery outlet.

Embodiments of the invention comprise methods and systems for optimizing coagulant dosing of raw water in a water treatment process. First, the embodiments determine the optimum dosage of pH adjusting chemicals to be added to the raw water based on a measurement of dissolved organic content, alkalinity, and pH of the raw water. Then, the embodiments perform a flocculation test of a mixture of the optimally-pH-dosed raw water and a hydrolyzing metal salt (HMS) wherein the dosage of the HMS salt in the mixture can be calculated based on a measurement of the charge demand of the optimally-pH-dosed raw water. The results of this flocculation test are compared to the results of at least one previous test of a combination of optimally-pH-dosed raw water and HMS to determine if the hydrolyzing metal salt dose is optimized. Once the HMS is optimized, the optimally-HMS-dosed optimally-pH-dosed water is tested with at least two different dosages of a polymer coagulant to determine the optimal polymer coagulant dosage to be used with the optimally-HMS-dosed optimally-pH-dosed water.

The invention relates to a method and apparatus for treating water. Iron is removed biologically from humus-rich water with the solution according to the invention. In the method, the water being treated is conveyed through a filter, which filter comprises filter material. Before the water is conveyed to the filter, the pH value of the water is lowered with an acidification part that is included in the apparatus.

An ocean alkalinity enhancement (OAE) system that reduces atmospheric CO.sub.2 and mitigates ocean acidification by electrochemically processing feedstock solution (e.g., seawater or brine) to generate an alkalinity product that is then supplied to the ocean. The OAE system includes a base-generating device and a control circuit disposed within a modular system housing deployed near a salt feedstock. The base-generating device (e.g., a bipolar electrodialysis (BPED) system) generates a base substance that is then used to generate the ocean alkalinity product. The control circuit controls the base-generating device such that the alkalinity product is supplied to the ocean only when (1) sufficient low/zero-carbon electricity is available, (2) it is safe to operate the base-generating device, and (3) supplying the alkalinity product will not endanger sea life. Modified BPED systems include features that facilitate autonomous system operations including enhanced maintenance cycle operations and a reduced reliance on external fresh water sources.

This disclosure is related to systems and methods for water treatment, storage and customization, and more particularly, to systems and related methods for water production, sanitation, adjustment, maintenance, storage and dispensing of potable water to a user. The systems and methods described herein can provide several advantages including providing consistent high-quality water at point-of-use locations, thereby avoiding inconveniences of transport, unpredictable or wasteful supply chains and/or alleviate water needs at remote locations. Furthermore, the systems and methods described herein can offer a seamless digital consumer experience with high accuracy reporting of water production, storage, quality and personalization for the user.

This disclosure provides techniques for detecting and/or inhibiting corrosion of a distribution/recirculation network for a fluid, e.g., an aqueous matrix (liquid). For example, the disclosed techniques can be used to measure and/or predict degeneration of pipes, solder joints and various other plumbing fixtures in a water distribution network or heat transfer recirculation network caused as a function of variation in environmental parameters. In one embodiment, a system builds a database by measuring metal corrosion (e.g., from lead or copper pipe, solder joint or other type of plumbing vessel or fixture) and correlating degradation of a layer of protective scale and/or metal concentrations present with measured environmental parameters; later, as conditions vary, the database (or associated correlation weights/values) may be used to predict degradation of scale health and/or corrosion stemming from short and/or long term water conditions, and to effectuate advance mitigation.
