Water Purification Process With Water Pretreatment

Abstract

A water purification process for treating water containing at least some organic contaminants, and including the steps of pre-treating the water for capturing organic contaminants from solution in a water stream, by passing the water into a spin up bowl to speed up the water stream, forcing the high speed stream through an annular flow passage located centrally of the spin up bowl passing the high velocity stream between a magnetic member and a magnetic ring, thereafter passing the water stream into an energy recovery bowl, directing the flow from the flow passage onto a zinc anode member; and thereafter passing the water stream along a grounded pipe, thereby causing the development of fine particles of calcium carbonates, and capturing the organic contaminants

What is claimed is: 
     
         1 . A process of reducing the contamination of reverse osmosis filtration media for water purification, comprising the steps of:
 creating a supply of raw source water incorporating both inorganic contaminant material and calcium bicarbonate contaminants and organic contaminants;   setting out some of said entrained inorganic contaminant material from the raw source water;   passing said source wafer as a tangential stream into an input spin-up chamber at a first predetermined speed;   creating a vortex of said source water in said spin up chamber thereby acceleration the speed of flow;   passing the accelerated source water stream through a centrally located annular flow passageway and into an output chamber;   establishing a radially aligned magnetic field across said passageway, between a magnetic ring positioned around said passageway, and a magnetic member positioned in said passageway within said magnetic ring;   subjecting said source water stream in said passageway to aligned radial magnetic fields for yielding a flow times magnetic field product in excess of 36,000 gauss-feet per second, thereby stripping hydrogen ions from bicarbonate ion groups and forming carbonate ions for capture by calcium ions and forming temporary calcium carbonates in excess of saturation levels in said water stream;   directing said source water stream containing said temporary calcium carbonates onto a zinc anode body in said output chamber;   passing said water stream through a conductive pipe and depositing fragile crystalline carbonate deposits in said pipe downstream of said output chamber, said fragile calcium carbonate deposits capturing organic contaminates in said fragile crystalline carbonate particles;   breaking off said deposited fragile crystalline carbonate particles into free crystalline carbonate particles;   entraining said fragile crystalline carbonate panicles with said water stream;   passing said water stream containing inorganic contaminants and said entrained calcium carbonate particles carrying organic contaminants to a reverse osmosis filtration unit, having a reverse osmosis media with an upstream and a downstream side;   passing water molecules through said reverse osmosis media to produce product water, while preventing passage through said media of said inorganic contaminants and said carbonate particles carrying said organic contaminants; and,   continuously removing said inorganic contaminants, and said calcium carbonate particles carrying said organic contaminants, from said upstream Side of said reverse osmosis media.   
     
     
         2 . The process of reducing the contamination of reverse osmosis filtration media for water purification as claimed in  claim 1  wherein the gap between the magnetic ring and the magnetic member is determined by the ion separation equation Bvq, where B is the magnetic field in gauss, v is the wafer velocity in feet per second, and the q's are the various set electric charge on the ions being separated. 
     
     
         3 . The process of reducing the contamination of reverse osmosis filtration media for water purification as claimed in  claim 2  wherein Bvq is between
 36,000×q and 120,000×q. 
 
     
     
         4 . The process of reducing the contamination of reverse osmosis filtration media for water purification as claimed in  claim 3  wherein the magnetic gap between said magnetic ring and said magnetic member measures between 1/16 inch and ¼ inch. 
     
     
         5 . The process of reducing the contamination of reverse osmosis filtration media for water purification as claimed in  claim 4  including the step of passing the wafer stream containing said calcium carbonate particles from said recovery bowl through an iron pipe, said iron pipe being connected both to said zinc body and to electrical ground.
