    Abstract: A ballast water treatment device capable of suppressing damage to a filter is provided. The ballast water treatment device is provided with: a filtering device including a filter for filtering ballast water; a plurality of lines for a flow of the ballast water; a ballast pump for pumping the ballast water to flow into the plurality of lines; and a control unit for controlling the ballast pump to cause the ballast water to flow into a desired line. The plurality of lines includes an object line connected to the filtering device, and a discharge line diverging from the object line and connected to an outside of a system. The control unit controls the ballast pump to discharge the ballast water remaining in the object line to the outside of the system via the discharge line, by causing a ballast water flow through the object line and the discharge line.

  • Patent number: 9370747
    Abstract: In a method and apparatus for reducing the total dissolved solids of a solution, a feed solution is conveyed to at least one first chamber of a unit, and a draw solution is conveyed to at least one second chamber thereof. A semi-permeable member arrangement is disposed between the chambers. The draw solution has a greater molar concentration than does the feed solution. Solvent from the feed solution is drawn through the membrane arrangement into the draw solution, reducing the solute concentration of the draw solution and increasing the solid concentration of the feed solution. Paddles provide continuous sweeping of opposite external surfaces of the membranes to reduce solute depositions on the surface facing the feed solution chamber, and to remove liquid permeate molecules from that external surface of the membranes that faces a draw solution chamber.

    Abstract: A Water and Wastewater Treatment Aerated Mini-Dosing air-lift pump System and filter housing, that replaces the conventional dosing pump, controls and additional Tank. It is adaptable to all access ports and uniquely smaller than a 3? inspection port and is integrally positioned in an existing or new raw water pretreatment or pump tank. It aerates the source pool thereby mitigating: H2SO4 gases, odors and source pool BOD5. The system communicates with an above ground aerator and optional controls and in it's plurality supplies dissolved and free oxygen to the pump, housing, effluent and the source pool, with surge protection and scum mitigation. Mini-metering and, low pressure, extended cycle durations increase the average microbial production balance and microbial Ratio to nutrients BOD. The raw sewage tank no longer requires gas removal prior to inspection due to oxic and anoxic microbial processes that mitigates H2SO4 gases.

    Abstract: Disclosed herein is a ballast water treatment device. The device includes a filtering unit filtering ballast water introduced into a ship using a filter, a vortex generating unit generating an artificial vortex in the ballast water filtered by the filtering unit, and an ultraviolet treatment unit having an ultraviolet lamp which sterilizes the ballast water discharged from the vortex generating unit using ultraviolet rays, thus preventing secondary contamination resulting from by-products, preventing a ballast tank from becoming contaminated, affording effective maintenance, and making it convenient to control. Further, an artificial vortex is formed in the ballast water when it is mixed, thus allowing a large quantity of ultraviolet rays to be radiated onto the ballast water passing through the ultraviolet treatment unit, therefore improving a sterilization effect.

A portion of the wastewater is diverted from a sewer main. The solids are separated from the liquid; for example, by a centrifugal separator such as a vortex or cyclone separator. The recovered liquid can be treated and made available for reuse or disposed of. The separated or concentrated solids are reintroduced into the sewer main dynamically in a portion that adjusts the wastewater loading, or alternatively, the solids loading, in the sewer main to a predetermined amount or predetermined range. The system can be adapted to reducing demand of wastewater volume flowing within a wastewater treatment plant by diverting the wastewater in the flow path between the wastewater plant inlet and the biological processing stage and reintroducing separated solids downstream.

  • Publication number: 20100122946
    Abstract: 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.

  • Publication number: 20090184057
    Abstract: A method of removing contaminant compounds such as residual pharmaceutical or cosmetic compounds found in drinking water. The method entails directing the drinking water into a water treatment device and injecting ozone into the drinking water to form a drinking water-ozone mixture. Thereafter the water-ozone mixture is held within a holding tank where the ozone oxidizes various contaminant compounds and reduces their concentration in the drinking water. From the holding tank, the water-ozone mixture is directed to an ultraviolet light chamber where the water is treated with ultraviolet light.
