20090236289 | Methods for Purging Absorptive Materials Used in the Removal of Contaminates from an Aqueous Medium - Methods, systems and apparatus are provided for purging an adsorptive material of entrapped particulates. Methods, systems and apparatus rely upon a reverse loop for reversing the flow of medium within an adsorption material, allowing particulates caught within the adsorption material to be preferentially moved through and out of the adsorption material. | 09-24-2009 |
20090283478 | METHOD AND SYSTEM FOR A REGENERATIVE PARTICLE TRAP STRUCTURE LOADED AND UNLOADED WITH ACTIVE MATERIALS BY WAY OF A FLOW STREAM - A method and system for treating a fluid by trapping particles of an active material suspended in a flow stream by way of a particle-trap structure so as to form a multi-layer filtering media to treat the fluid. The particle trap is fully regenerative configured so that the particles are readily back flushed after achieving their absorption capacity in preparation for loading a fresh charge of active particles. The method also describes a combination of a centrifuge separator in-line with the regenerative particle trap configured such that the separator first removes contaminants of considerably different specific gravity than the fluid and the regenerative active particle trap then removes the remaining contaminants by absorption or chemical treatment. | 11-19-2009 |
20100320152 | Apparatus and Method for Isolation from and Support of a Carbon Filtration System from an Ion Exchange System - A combination filtration and ion exchange system is provided. In one embodiment, the system includes a valve rotor, a carbon treatment tank, an ion exchange treatment tank and a valve. The valve rotor having a source water inlet, a service water outlet, a water treatment outlet, a water treatment inlet and a drain outlet. The carbon treatment tank having a service inlet and a service outlet, the service inlet coupled to the water treatment outlet. The ion exchange treatment tank having a service inlet and a service outlet, and the service outlet is coupled to the water treatment inlet. The valve having a carbon tank port, an ion exchange port, and a water treatment outlet, and a valve member having a first position and a second position, wherein in the first position, the service inlet of the ion exchange treatment tank is in fluid communication with the service outlet of the carbon treatment tank, and in the second position, the service inlet of the of the ion exchange treatment tank is in fluid communication with the water treatment outlet. | 12-23-2010 |
20110100922 | TREATMENT VESSEL FOR A WASTE WATER TREATMENT PROCESS SYSTEM - A treatment vessel ( | 05-05-2011 |
20130134100 | Compacted Filter Beds Comprising Non-Sintered, Buoyant Filter Media and Methods Relating Thereto - Compacted filter beds comprising a non-sintered, buoyant filter medium may be useful in fluid filtration apparatuses and methods. For example, a method may include filtering a first fluid through a filter bed that is compacted, the filter bed comprising a non-sintered, buoyant filter medium that is mechanically compacted; and backflushing a second fluid through the filter bed so as to fluidize the non-sintered, buoyant filter medium. | 05-30-2013 |
20130153507 | METHOD FOR OPERATING WATER SOFTENING DEVICE AND WATER SOFTENING DEVICE - A method for operating a water softening device, includes: producing soft water by passing raw water downward through a cation exchange resin bed which has a depth of 300 to 1500 mm and a ratio of the depth to a diameter being 1.8 to 3; and regenerating all the bed by generating an opposite flow of a regenerant by collecting the regenerant at an intermediate portion of the bed while supplying the regenerant from top and bottom sides of thereof, wherein the regenerating includes supplying the regenerant in a volume which gives a regeneration level of at least 1 to 6 eq/L-R, to a hardness leak prevention bed having a depth of 100 mm, and the producing after the regenerating includes supplying raw water having an electric conductivity of equal to or lower than 150 mS/m and having a total hardness of equal to or lower than 500 mgCaCO | 06-20-2013 |
20140166582 | WATER TREATMENT SYSTEM AND METHOD - Embodiments of a water treatment system, a water treatment method, and an ozone kit for a water treatment system are provided. The water treatment system includes an ozone gas source; a regenerating fluid source; a water tank; a manifold having a first port in fluid communication with the regenerating fluid source, a second port in fluid communication with an outlet of the ozone gas source, and a third port in fluid communication with the water tank via a venturi nozzle; and a control system configured to: cause regenerating fluid to be drawn through the venturi nozzle into the water tank; and cause ozone gas to be drawn through the venturi nozzle into the water tank. | 06-19-2014 |
20140263076 | BAFFLE PLATE FOR A WATER TREATMENT DEVICE - A fluid treatment device includes a tank containing a fluid treatment medium and a fluid. A distributor plate is received in the tank and separates the bed from a lower end portion of the tank. A baffle is positioned beneath the distributor plate and is configured to direct fluid exiting a riser tube of the fluid treatment device toward the peripheral of the tank to thereby provide a more evenly-distributed flow through the radius of the distributor plate and through the fluid treatment medium. The baffle may have a downwardly facing concave surface that traps air bubbles generated during a brine draw operation. | 09-18-2014 |
20160002066 | WATER TREATMENT APPARATUS AND WATER TREATMENT METHOD USING THE SAME - A water treatment apparatus is a water treatment apparatus including a cylindrical main body placed in a substantially perpendicular direction; a plurality of treatment layers disposed at intervals and in an axial direction in the main body, each of the plurality of treatment layers having particles contained therein and having a pair of partition plates for preventing upward and downward outflow of the particles; an air bubble supplying portion for supplying an air bubble into the main body from below; a backwash water supplying portion for supplying backwash water into the main body from below; and a discharge portion disposed above each treatment layer in the main body, for discharging at least one of the air bubble and the backwash water, wherein a space portion is provided between an upper partition plate and the particles of the treatment layer in a steady state. | 01-07-2016 |
