Abstract: The present invention relates to a method for production of potable water by removal from water of an aqueous environment selected from a river, a lake, a reservoir, a pond, a stream, groundwater, spring water, surface water, or combinations thereof, organic colloidal particles of biocontaminants. The method comprises applying to the water at least one nanocomposite consisting of a mineral platform, which is denser than water, and at least one polyelectrolyte polymer adsorbed to said mineral platform with charge opposite to the charge of the colloidal particles.

Abstract: A system for treatment of a polluted effluent includes an outer chamber and a computerized control system. The system is configured to treat an effluent/catalyst mixture that includes the polluted effluent in admixture with a purification slurry. The slurry includes particles of one or more catalysts and/or organoclays. The treatment of the effluent/catalyst mixture is carried out by contact between the particles of the catalysts and/or organoclays and the polluted effluent to mineralize or degrade pollutants in the polluted effluent.

Abstract: A system for treatment of a polluted effluent, includes an outer chamber configured to treat the polluted effluent in mixture with a purification slurry including particles of one or more catalysts and/or organoclays, or a mixture thereof. The outer chamber includes (i) a stirring unit consisting of an engine and a stirrer, configured to mix the polluted effluent and the purification slurry to prevent the particles from sinking without causing a turbulence, (ii) a membrane located at the top of the outer chamber through which a treated effluent passes, while preventing the particles of one or more catalysts and/or organoclays from exiting the outer chamber together with the treated effluent, (iii) a membrane cleaning system configured to remove and collect the particles of one or more catalysts and/or organoclays accumulated on the membrane, and re-introducing the particles back to the bottom of the outer chamber.

Abstract: A method for production of potable water by clarification of water of an aqueous environment including suspended charged mineral, organic colloidal particles that may be of biocontaminants, and mixtures thereof, the method comprising applying to the water at least one nanocomposite consisting of: (a) a mineral platform which is denser than water and most organic compounds and (b) at least one polyelectrolyte polymer adsorbed to said mineral platform with charge that opposes the charge of the suspended colloidal particles.

Abstract: A method for pretreatment of wastewater or recreational water with substantial reduction of total suspended solids and turbidity in a very short time is provided comprising treatment with nanocomposites and a bridging agent.
