Provided is a water-purifying agent formed of a granulated product including a mixture of a plant powder and a polymeric flocculant, wherein a surface of the granulated product includes a coated portion in which the plant powder is coated with the polymeric flocculant and a non-coated portion in which the plant powder is not coated with the polymeric flocculant.

A water treatment system is disclosed having 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 horizontal-vertical drain board-flocculation vacuum preloading sediment treatment method, including (1) electro-osmotic electrodes disposed on the top and bottom of each reinforcing bar of the reinforced frame; (2) after the sediment is blown to the bottommost layer of vacuum preloading tank, the support is fitted over each reinforced frame, and the clips are fastened; (3) the transverse drain board passes through the support, one end of transverse drain board is connected to a curved tube; (4) repeat Step 2 and Step 3 until the sediment is blown to the surface layer of vacuum preloading tank; (5) a vertical drain board is arranged vertically between two adjacent rows of reinforced frames; (6) the curved tube is connected to the first junction block through the second junction block, and then the geotextile and sealing film are laid, the vacuum pump and power supply are switched on at last.

Systems and methods for dosing slurries to remove suspended solids from the slurry are disclosed. The systems and methods may be used to dewater slurries having relatively high solids content such as earthen slurries. In some embodiments, the zeta potential of the slurry is monitored by an electroacoustic zeta potential sensor to control coagulant addition.

A method for continuous supply of peracetate oxidant solution with activity to generate to generate reactive oxygen species includes production processing in a liquid stream starting with a feed water and sequentially adding alkali concentrate, hydrogen peroxide solution and acetyl donor and introducing a resulting peracetate oxidant solution into a product buffer tank from which the peracetate oxidant solution is dispensed for use as a reactive oxygen species-generating oxidant, In the product buffer tank peracetate oxidant solution has a pH in a range of from pH 10 to pH 12, a molar ratio of peracetate anions to peracid in a range of from 60:1 to 6000:1 and a molar ratio of peracetate anions to hydrogen peroxide of greater than 16:1.

A composition for solid pellets and a process for removing water from particulate material slurries produced by horizontal drilling, vertical drilling and dredging of bodies of water are disclosed. The composition comprises a precipitating agent, a purification agent and, optionally, a binding agent. The process comprises the steps of 1) water removal accomplished by diffusing a chemical reagent into the particulate material source stream that results in separating out a clean water fraction and 2) reacting the sludge with a demulsifier and a superabsorbent polymer that locks onto the water in the remaining slurry thus turning the slurry into a solid crust. The crust is ground into a particulate form and disposed in a landfill. The combined effect of the treatments is the thickening of the particulate material slurry from about 10% solids to about 25% solids. The removed water may be used for further drilling and drinking.

A method for treating wastewater is provided. The method uses a cationic mineral composition, which is a cationic clay composition, to assist with flocculating out biomass suspended within the wastewater. The cationic clay composition may be mixed with the wastewater undergoing a wastewater treatment process at numerous injection sites. Mixing the cationic clay composition with wastewater at these injection sites may provide different benefits, wherein these benefits are dependent on the point at which the wastewater is along the wastewater treatment process. The cationic clay composition may be added at one injection site or multiple injection sites, depending on a determination made by the operator.
