Abstract
Abstract An electromagnetic ground water conditioning system and sampling device comprising a holding tank, a pump, filters and timers to regulate the time and duration of blowout of settled solids at the bottom of the tank. The electromagnetic water conditioning unit is that disclosed and claimed in my allowed patent application Ser. No. 153,219 filed May 27, 1980, entitled Free Flow Non-Corrosive Water Treatment Device, now U.S. Pat. No. 4,288,323. A blowout valve at the bottom of the tank is solenoid operated and regulated to discharge a small liquid volume of settled solids. One timer is a 24-hour timer to set the blowdown start, the other is a 30-minute timer which sets the duration of the blowdown. For ground water or sewage water or industrial waste water a 2-hour setting on the 24-hour timer and a 10-second setting on the 60-second timer is preferred. The amount blown out is 1/10 gallon. This assembly and system is especially useful for sampling and monitoring industrial waste water, or industrial effluent, for preparing makeup water for fermentation and non-chemical sterilization and for the treatment of ground water containing toxic heavy metals in solution by hydrogen sulfide alone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
291 words
An electromagnetic ground water conditioning apparatus comprising: a holding tank with an inlet and an outlet for holding ground water which is treated in said apparatus; an electromagnetic water conditioning unit comprising an inlet from said tank, a ferromagnetic casing, an electromagnetic winding surrounding said casing to create a magnetic field of about 3,000 oersteds on said casing, an impeller mounting in bearings at each end of said casing which rotates in response to the water pressure from said inlet and a water outlet at the other end of said casing; a pump between said holding tank outlet and said electromagnetic unit; a semicircular band fitted with flanges which encircles said holding tank and is adapted to hold a bracket supporting means to mount said electromagnetic unit at about the middle of said holding tank; a bracket connected to said band to mount said electromagnetic water conditioning unit; a pipe means connecting said pump to the inlet pipe of said electromagnetic unit; a filter means between said pump and inlet pipe fed by water passing through said pipe means; said pipe means further connecting said filter means to the outlet of said electromagnetic unit; a return line from the outlet of said filter to said holding tank for recirculating water from said filter back into said holding tank by the pumping action of said pump into said electromagnetic water conditioning unit; and a blowdown unit comprising timing devices electrically connected to a solenoid operated drain valve at the bottom of said tank whereby solids precipitated by the electromagnetic treatment in said electromagnetic unit are blown out of said tank for predetermined short intervals of the order of seconds to thereby clarify the incoming water without the need for water treatment chemicals.
Claim 2
Dependent Claim
291 words
An electromagnetic ground water conditioning apparatus comprising: a holding tank with an inlet and an outlet for holding ground water which is treated in said apparatus; an electromagnetic water conditioning unit comprising an inlet from said tank, a ferromagnetic casing, an electromagnetic winding surrounding said casing to create a magnetic field of about 3,000 oersteds on said casing, an impeller mounting in bearings at each end of said casing which rotates in response to the water pressure from said inlet and a water outlet at the other end of said casing; a pump between said holding tank outlet and said electromagnetic unit; a semicircular band fitted with flanges which encircles said holding tank and is adapted to hold a bracket supporting means to mount said electromagnetic unit at about the middle of said holding tank; a bracket connected to said band to mount said electromagnetic water conditioning unit; a pipe means connecting said pump to the inlet pipe of said electromagnetic unit; a filter means between said pump and inlet pipe fed by water passing through said pipe means; said pipe means further connecting said filter means to the outlet of said electromagnetic unit; a return line from the outlet of said filter to said holding tank for recirculating water from said filter back into said holding tank by the pumping action of said pump into said electromagnetic water conditioning unit; and a blowdown unit comprising timing devices electrically connected to a solenoid operated drain valve at the bottom of said tank whereby solids precipitated by the electromagnetic treatment in said electromagnetic unit are blown out of said tank for predetermined short intervals of the order of seconds to thereby clarify the incoming water without the need for water treatment chemicals.
Claim 3
Dependent Claim
63 words
An apparatus as claimed in claim 1 including support means at the bottom of said holding tank to adapt a sample to be taken of the blowdown at the bottom thereof and wherein said timing devices comprise a twenty-four hour timer and a thirty minute timer, each of said timers being adjustable to preset the time of blowdown and the duration of blowdown.
Claim 4
Dependent Claim
53 words
An apparatus as claimed in claim 2 wherein said holding tank is provided with a sampling pipe connected to the tank at the top and a valve with a petcock by means of which a sample of water representative of the entire volume of said holding tank may be drawn through said petcock.
Claim 5
Dependent Claim
37 words
An apparatus as claimed in claim 3 wherein said filter means is provided with a disposable cartridge filter having a predetermined pore size of the order of twenty microns to remove solid particles larger than said pores.
Claim 6
Dependent Claim
38 words
An apparatus as claimed in claim 4 wherein the outlet pipe from said holding tank is combined with an ultraviolet sterilizer whereby water entering said sterilizer is irradiated by radiation effective to kill microorganisms, viruses, fungi and bacteria.
Claim 7
Dependent Claim
90 words
An apparatus as claimed in claim 1 wherein said holding tank is combined with a source of hydrogen sulfide and bubbling means for said hydrogen sulfide to dose the incoming water with an amount of hydrogen sulfide of the order of 5-10 parts per million whereby any heavy metal salts contained in the incoming water supply are subjected to precipitation as insoluble solid particles of heavy metal sulfide in said holding tank whereby said precipitated sulfide in the form of fine particles is removed by filtration in said filter means.
Claim 8
Dependent Claim
95 words
An apparatus as claimed in claim 1 wherein said holding tank assembly with filter, pump, and support means is combined with another assembly of the same construction in series and the capacity of the combined assembly is doubled to thereby adapt the holding tank apparatus for dilution in the treatment of chemical waste and fermentation waste, the dilution being achieved by adding water in one said assembly to fermentation or chemical waste in the other said unit so that circulation between the two assemblies effectively dilutes the concentration of the waste by about fifty percent.
Claim 9
Dependent Claim
27 words
An apparatus as claimed in claim 7 wherein said assembly is connected to an ultraviolet sterilizer for irradiating the circulated liquid with ultraviolet light to destroy microorganisms.
Claim 10
Dependent Claim
25 words
An apparatus as claimed in claim 8 wherein a short communicating pipe connects said sterilizer to the outlet from said one electromagnetic water conditioning unit.
Claim 11
Dependent Claim
80 words
An apparatus as claimed in claim 1 wherein said holding tank has a capacity of forty gallons and said impeller has at least six turns to that the electromagnetic water conditioning is responsive to a pressure difference from said pump of about 1-2 pounds per square inch which occurs when a water faucet in a lavatory connected to the apparatus is opened with said water conditioning system operationally connected thereto, the impeller rotating in response to said drop in pressure.
