Water Treatment Patent

Water treatment process and apparatus and device for the distribution of water to be treated into and for the recovery from washing liquid from a water treatment filter apparatus


A device for the distribution of water to be treated into and for the recovery of washing liquid from a water treatment filter apparatus of the type including a tank containing therein a filter material includes a channel coupled to and extending along the length of the tank, the channel receiving therein water to be treated. The channel has an opening into the interior of the tank at a level above the filter material. The opening is defined at the lower portion thereof by an overflow over which the water to be treated flows from the channel to the tank. The overflow includes a first inclined plane inclined downwardly and away from the channel in a direction toward the tank and a second inclined plane inclined downwardly and toward the channel from the first inclined plane. The inclined planes extend into the tank and form a deflector structure to prevent any filter material from passing through the opening during backwashing of the filter material.

Waste water treatment system and process


An improved process and a system for waste water treatment are disclosed which are particularly suited for use in industrial plants (10) having existing drainage trench networks (108-128) through which normal plant effluents, component leakage and accidental spills ordinarily would be allowed to flow. The trench system is connected to a waste water treatment facility (FIG. 1) designed to remove impurities from the effluents and return acceptably clean water to the plant for reuse or discharge it to the environment. Because some plant effluents, component leaks and unexpected spillages can increase the concentration of impurities in the waste water to levels beyond the design limits of the waste water treatment system, a series of dams (138-144, 150-154, 162-176) are provided at locations throughout the trench network so that effluents having rather high ranges of concentration of impurities are held behind the dams. Effluents having relatively low ranges of concentration are directed into isolated trenches (108) or a pipe network (178, 180) located in the trenches, the pipes then being led through sealed apertures in the dams to discharge to the waste water treatment system. The highly concentrated effluents are periodically pumped (148, 192) from behind the dams and discharged to a portion (76-106) of the waste water treatment system in which their impurities are concentrated for disposal in solid form.

Control system for meter actuated regeneration in a water treatment system

This invention relates to a control system for regeneration of a water treatment system in which a water meter monitors water usage and mechanically drives a water volume wheel to an operative position to call for regeneration when a predetermined volume of water has been treated and then automatically resets itself. A timer wheel driven by a motor is included within the control system such that the timer wheel and the water volume wheel coact to activate the regeneration cycle mechanism at a predetermined time after a predetermined volume of water has passed through the water meter. The mechanism is adjustable relative to the water treating capacity of the treatment system and the condition of the water being treated so as to be able to vary the predetermined volume of water treated which will call for regeneration.
