20090314702 | Rapid transfer and mixing of treatment fluid into a large confined flow of water - A system for rapid transfer and mixing of treatment substance into a larger confined flow of water. By-pass flow from the main flow receives treatment substance and returns to the main flow through a pair of directly opposed nozzles are directed across the main flow. | 12-24-2009 |
20100193421 | FLUID TREATMENT SYSTEM - In one of its aspects, the present invention relates to a fluid treatment system comprising: an inlet; an outlet; a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone: (i) comprises a first wall surface and a second wall surface opposed to the first wall surface, and (ii) having disposed therein at least one array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis transverse to a direction of fluid flow through the fluid treatment zone and each of the first wall surface and the second wall surface comprises a first fluid deflector element and a second fluid deflector element. The first fluid deflector element projecting into the fluid treatment zone to a greater extent than the second fluid deflector element. | 08-05-2010 |
20100224545 | Membrane Module for Fluid Filtration - Embodiments of the invention provide a membrane module including a first plurality of fibers capable of filtering fluids that are helically wound in layers creating a mono helix. Fluids to be treated can flow radially with respect to a longitudinal axis of the mono helix or parallel to the longitudinal axis of the mono helix. The membrane module can further include a second plurality of fibers that are helically wound with the first plurality of fibers to create a dual helix. The second plurality of fibers can have different properties than the first plurality of fibers in order to achieve different filtering functionalities. | 09-09-2010 |
20100236999 | SCUM REMOVING APPARATUS - A spraying means is arranged on the scum-flowing wall surface side of wall surfaces forming a scum inlet of a scum discharging mechanism. The spraying means sprays pressured water upward along the wall surface on the scum-flowing side from when a part of the scum inlet is submerged in water until the scum begins to flow into the scum inlet. As a result, even large lumps of scum exceeding 10 cm in thickness (diameter) may be lead smoothly into a pipe by the pressured water, and the amount of discharged water accompanying scum discharge may be reduced to 1/20 to 1/30 than by a conventional scum removing apparatus. | 09-23-2010 |
20110084012 | HYDROCYCLONE FLOTATION SYSTEM AND WATER POLLUTION PREVENTION SYSTEM EQUIPPED WITH THE SAME - The present invention discloses a hydrocyclone floating separator, comprising: a vortex generating body which includes a water inlet, swirls water introduced through the water inlet, and includes a water outlet discharging the swirled water; an air injection unit for injecting air into water introduced through the water inlet; a drain control unit for controlling the amount of water discharged through the water outlet such that the level of the water in the vortex generating body is maintained constant; and a suspended solids removing unit for taking suspended solids out of the vortex generating body, the suspended solids existing dispersed in water being supplied to the vortex generating body and then floating and gathering towards the center of the vortex of the water surface because of the swirl flow of the water and the buoyancy of air bubbles charged in the water. Thus, the water pollution prevention system comprising the hydrocyclone floating separator can effectively treat suspended solids produced from a process of purifying waste water, sewage, service water, etc., at a relatively low cost. | 04-14-2011 |
20110180470 | AQUEOUS IRON REMOVAL PROCESS AND APPARATUS - A process and associated apparatus to reduce both ferrous (Fe | 07-28-2011 |
20110297601 | PHYSICAL WATER PURIFIER - A physical water purifier includes a tubular housing and permanent magnets arranged at a specific distance from one another in the tubular housing in a region of the tubular housing facing a water connection. The permanent magnets are arranged so as to form a pumping and eddying effect. The permanent magnets are produced from an anisotropic magnetic material. | 12-08-2011 |
20120145618 | GRAVITY FEED WATER TREATMENT SYSTEM WITH OXIDATION AND DISINFECTION STEPS - A portable water treatment system includes at least one sub-system to treat water including a primary disinfection system and a residual disinfection system. The water treatment system may include multiple sub-systems for treating water that feed into one another. The residual disinfectant may be administered to the water at a level below the taste threshold to prevent backgrowth of bacteria while leaving the taste of the water unaffected. The portable water treatment system may be designed to dispense water at a high-flow rate. | 06-14-2012 |
20130193053 | Water Container Having Germicidal Water Purification Unit - A water container having a germicidal water purification unit. Water stored in a reservoir passes through a conduit that extends through an array of light sources that operate in at least one of the visible light frequency range and the ultraviolet frequency range to purify the water. The light sources are activated, preferably on a selected as needed basis, by a power supply. | 08-01-2013 |
