Abstract: An apparatus, a system and a method for obtaining sieved water, for fighting fires, from a source of water having foreign objects are disclosed. A strainer is connected to a tank via a hose such that water may be pumped from the strainer to the tank. The strainer includes a water inlet having a sieve-like material over it and a water outlet connector where the hose connects. The strainer is submerged in a source of water such as a pond or stream. As water enters the strainer via the water inlet, the sieve-like material prevents foreign objects such as rocks and leaves from entering the strainer. Therefore, the foreign objects never reach the tank. A pan may be connected to the bottom of the strainer to elevate the strainer above the bottom of the source of water. Such elevating helps achieve desired flow rates without stirring or roiling foreign objects such as sand or gravel that may be at the bottom of the source of water.

There is a product-delivery component with a feed pipe at the higher end of the screen and a receiving chamber with a drain pipe for the separated liquid below the screen. To ensure that the screen is uniformly loaded over its total effective width and that the quality of the separated solids will accordingly remain constant as the product and feed conditions vary, the screen housing is mounted in such a way that it can be pivoted around a horizontal axis in order to vary its angle of inclination to the horizontal.

Abstract: A specially shaped vessel containing a mixture of solid matter and liquid in which fresh liquid and fresh solid matter are introduced at one end and the processed liquid and solid matter are extracted at the other end. When such a vessel stands, both ends act as the two sides of a communicating vessel arrangement. The liquid levels are always the same on both sides of said vessel. Liquid is poured out from only one end through a spout equipped with a strainer to prevent the solid matter from leaving the vessel. Both ends are covered by a separate lid. To add fresh liquid and solid matter and to extract steeped solid matter, the lid covering the proper end is taken off, while the vessel is standing. To pour liquid fully processed, the lids are left in place, but the outlet lid needs only be turned slightly. As needed, both fresh liquid and solid matter to be steeped are introduced through the inlet end.

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.
