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.
