摘要： A method for forming and immobilizing small particles on a filter substrate using a first and second polymer solution, a solution of sodium bromide and a solution of a metal salt. The method adjusts the pH of at least one of the first and second polymer solutions, immersing the filter substrate in the first polymer solution and immersing the filter substrate in the second polymer solution. The method includes repeating the steps of immersing the filter substrate in the first solution and the second solution alternately until desired number of layers is achieved. The method allows for the filter substrate to be immersed in the solution of the metal salt and subsequently in the solution of sodium bromide.

摘要： The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

摘要： The method of purifying spent brine from the regeneration of ion exchange resin, for example resin in water softeners. The method comprises acidifying the spent brine to a pH of less than 3 with an acid other than sulfuric acid, which acid is preferably chosen from at least one acid which forms a calcium salt that is more water soluble than calcium sulfate. One passes the brine through a nanofiltration membrane to purify the brine by separating from it a waste stream which comprises the majority of the polyvalent ions present, so that the purified brine has most of its contaminating polyvalent ions removed.
