  • Patent number: 10639587
    Abstract: An exhaust purification system has a centrifuge filter, a first fan device, a second fan device, a pump, and an ozone generator. The centrifuge filter has a container having a waste gas treating area and a wastewater treating area. The first fan device communicates with and draws gas into the waste gas treating area. The second fan device communicates with and draws the gas out of the waste gas treating area. The pump communicates with and draws wastewater from the wastewater treating area. The ozone generator communicates with the pump and introduces ozone into the wastewater inside the pump. A part of the ozone dissolved in the wastewater is released to the waste gas treating area to react with the gas, and the other part of the ozone dissolved in the wastewater reacts with the wastewater.

  • Patent number: 8613859
    Abstract: Synergistic mixtures of haloamines and their use to control the growth of microorganisms in aqueous systems are disclosed. The method of using the synergistic mixtures entails adding an effective amount of a monohaloamine and an effective amount of a dihaloamine to an aqueous system. The ratio of monohaloamine to dihaloamine is selected to result in a synergistic biocidal effect.

  • Patent number: 8591740
    Abstract: A chlorine based biofouling control subsystem is utilized to facilitate shipboard water management systems such as ballast water management that employ filters. The biofouling control system can serve as a subsystem to promote antifouling and reduce the filter clogging due to biofouling, which improves the efficiency and effectiveness of the ballast water treatment management system. An antifouling agent of the biofouling control system breaks up the dense colonies of marine organisms being filtered or treated by the main water management systems.

  • Publication number: 20130299434
    Abstract: A system for removing ammonia from wastewater includes a series of interconnected reactor tubes that each comprise an outer cathode and an inner cathode that is centrally positioned within the outer cathode to form a spacing of between 3 mm and 10 mm through which wastewater may flow. At least one of the reactor tubes includes an inner cathode having a MMO coating. Hypochlorite or another chlorine based element can be supplied to wastewater prior to passing through the reactor tubes. The presence of the hypochlorite within the wastewater and the generation of chlorine by the MMO coated cathode result in an increased level of hypochlorite being present in the wastewater which speeds the breakdown of ammonia. A portion of the wastewater processed through the reactor tubes can be diverted through a feedback path to the input to the reactor tubes to increase the amount of hypochlorite present in the unprocessed wastewater.

  • Publication number: 20130292335
    Abstract: The present invention provides processes for removing nitrogen species from fresh water or high salinity water recirculated aquaculture systems. The processes are based on physico-chemical treatments which are performed at ambient temperatures and at low p H values thus keeping the total ammonia nitrogen concentrations below a value which is considered detrimental for the growth or survival rate of cultured fish/shrimp.
