Publication number: 20140151276Abstract: A wastewater geothermal heat system is supplied with processed wastewater through a drip field in proximity to a thermal array part of a geothermal heat pump system. The wastewater treatment system portion provides a periodic source of treated wastewater. Several sensors and a control system regulate a pump that discharges wastewater from the treatment system and enters a drip field where it is released into the surrounding soil. The dampened soil provides an efficient vehicle to transfer heat into or out of a thermal array which is positioned adjacent to the drip field such that it is in contact with the soil that is dampened by the discharged wastewater.Type: ApplicationFiled: February 7, 2014Publication date: June 5, 2014Applicant: A.K.

Patent number: 8424554Abstract: An improved control valve for a reverse osmosis (RO) water purification system for supplying relatively pure water for on-demand dispensing, wherein the improved control valve positively terminates pure water production and brine outflow to a waste or drain when a pure water reservoir reaches a substantially filled condition. The control valve responds to a predetermined pressure differential between a tap or feed water inflow and produced pure water to close a pure water outflow line when the pure water reservoir reaches a substantially filled condition, thereby positively preventing further production of pure water. Shortly thereafter, the control valve closes a brine outflow line thereby positively preventing further water flow through the system until at least a predetermined volume of the reservoir-stored pure water is dispensed. When this occurs, the control valve re-opens in sequence the brine outflow and the pure water outflow lines.Type: GrantFiled: March 30, 2010Date of Patent: April 23, 2013Inventor: Bruce D. Burrows

Patent number: 8404121Abstract: The disclosure relates to a separation process. An aerated inlet mixture of fluid and solids is fed to a flotation separation vessel and is separated into an upper float layer and a lower clarified layer. The upper float layer is withdrawn from the vessel when the height of the upper float layer exceeds the height of an overflow conduit and forms a concentrated solids effluent. The lower clarified layer is withdrawn from the separation vessel as a clarified fluid effluent. The separation process is performed continuously using a control process that maintains a relatively stable distribution between the lower clarified layer and the upper float layer. The control process is a closed loop process that monitors the instantaneous height of the vessel contents and computes an error function based on the instantaneous height and a set-point height. The error function is used to periodically adjust the outlet flowrate of the clarified fluid effluent. The resulting process has improved stability (e.g.Type: GrantFiled: August 11, 2009Date of Patent: March 26, 2013Assignee: Anaergia Inc.Inventors: Joel Bias, Brian Ross

Publication number: 20120018358Abstract: A filter apparatus, provided for installation in a fluid storage tank, having at least one preferably replaceable filter element (11), through which a fluid can flow from the outside to an inner hollow filter chamber (19), forming the clean side, and which is surrounded by a housing wall (1) which forms a fluid chamber (15), into which the cleaned fluid from the inner hollow filter chamber (19) can flow, the housing wall having at least one wall opening (31) which forms a fluid passage located within the region of the variable fluid level in the storage tank. Said filter apparatus is characterized in that a control device (39, 41, 43) is provided which can be actuated as a function of the fluid level the storage tank and brings the fluid passage of the at least one wall opening (31) close to the position of the surface of the fluid in the storage tank.Type: ApplicationFiled: March 10, 2010Publication date: January 26, 2012Inventors: Norbert Sann, Michael Sakraschinsky, Stefan Hennes

Patent number: 8083934Abstract: A water disinfection apparatus includes a chamber adapted for connection to a pressurized water source. An ultra violet light is oriented to shine ultra violet rays into the chamber and to disinfect water therein, and a normally closed output valve connects the chamber to a supply valve. A control senses when a connected supply valve has been opened, and is operative to turn the ultra violet light on when the connected supply valve is opened; open the output valve after the ultra violet light has been turned on; close the output valve off after a supply time period expires; and turn the ultra violet light off when the output valve has been closed. The ultra violet light is turned on at all times that the output valve is open.Type: GrantFiled: December 5, 2008Date of Patent: December 27, 2011Inventor: Udo Staschik

Patent number: 8083936Abstract: The production of purified water from a residential reverse osmosis drinking water system is limited by the pressure build up in the holding tank or reservoir. While the pressure in the tank increases the brine or waste water continues to flow at a constant rate. This condition makes an undesirable out of proportion relationship between the purified water and the waste water. The production of product water is controlled by the differential pressure across the purification membrane, as the tank pressure increases the differential pressure decreases and reduced production of product water results. The purpose of the device is to utilize the increasing tank pressure as a force to actuate the valve that proportions the waste water in a direct relationship with the product water. The ratio between the product water and the waste water remains constant during the period that purified water is being delivered to the holding tank.Type: GrantFiled: March 3, 2009Date of Patent: December 27, 2011Inventor: Robert Walker

Publication number: 20110271704Abstract: Systems and methods for condensate removal are disclosed. A reservoir may include a trap structure and a sediment trap may be disposed within the trap structure. The sediment trap may be positioned within the reservoir so that condensate flowing into the reservoir is filtered before flowing out of the reservoir.Type: ApplicationFiled: April 15, 2011Publication date: November 10, 2011Applicant: LITTLE GIANT PUMP COMPANY LLCInventors: James J. Volk, Ryan A. Johnson

Publication number: 20110186507Abstract: A system and method for processing and reusing graywater. At least two vertical flow wetland units are provided, each of which comprises a container filled with at least one granular substrate and at least one species of a hygrophilous plant, and an outlet. At least one of the wetland units is set to an inactive state during a predetermined period of time such that influx of graywater to each of the inactive units is prevented, to regenerate each inactive wetland units. At least one of the wetland units is set to an active state to allow introduced graywater to be purified. Purified graywater is discharged from the outlet of each active unit to a sink. At least a portion of the purified graywater is recirculated to each active wetland units so that a portion of the purified graywater, when desired, is discharged to a domestic site for reuse.Type: ApplicationFiled: October 11, 2009Publication date: August 4, 2011Inventor: Moshe Elazar Ernest

Patent number: 7981287Abstract: A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.Type: GrantFiled: August 2, 2010Date of Patent: July 19, 2011Assignee: Sionix CorporationInventors: David P.
