  • Patent number: 6464210
    Abstract: An apparatus for the efficient dissolution of fluids, both gas to liquid and liquid to liquid. A flow splitter divides the influent to an upper and lower stream. The lower stream is injected with a gas and the gas-enriched lower stream is subsequently discharged proximate to the bottom of a contactor in tangential fashion. The upper stream is discharged in similar tangential fashion proximate to the top of the contactor producing a vortex flow pattern. The countercurrent flow of the gas-enriched lower stream and upper stream ensures a high degree of dissolution of the gas in the liquid. Alternatively, two liquids of differing densities may be dissolved together with the present invention.

  • Patent number: 6418580
    Abstract: A treatment apparatus and method that greatly increases the efficiency and flexibility in using ozone in the laundry process by permitting an operator to set the level of dissolved ozone concentration delivered to the washing machines, depending upon the amount and type of soil on the laundry. Furthermore, the present invention ensures that there is enough dissolved ozone available in the wash water to meet the demand of the washing apparatus. Lastly, the present invention monitors and maintains the desired amount of dissolved ozone to be delivered to the washers.

  • Patent number: 6398959
    Abstract: The present invention is drawn to a unique apparatus and method for treating and reusing the wastewater discharged from agricultural animal farms. The apparatus and method of the present invention may be readily-sized and configured depending upon the amount and constituent(s) of the wastewater to be treated. In a first embodiment, the apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or land applied. In use, the apparatus and method of the first embodiment may actually require addition of make-up water during periods of low rainfall to make up water losses due to evaporation and drift. It is contemplated that the only byproduct of the apparatus and method of the first embodiment may be a beneficial sludge if a sufficient number of installations are operated.

  • Patent number: 6395174
    Abstract: The present invention is drawn to a unique apparatus and method for treating anaerobic bodies of water including, but not limited to, agricultural waste treatment lagoons. The apparatus and treatment method of the present invention will consist of several phases once the parameters of the wastewater have been ascertained. First, specially selected bacteria are cultivated based upon the wastewater parameters. This specialized bacteria is then utilized in bio-augmentation of the wastewater lagoon. Specifically, bacteria will be isolated and propagated specific for the wastewater which will create a selective dominance within the lagoon and enhance digestion of the waste. The wastewater lagoon is equipped with an aeration means and mixing means such that the wastewater undergoes aerobic digestion utilizing the specially selected bacteria. The solids separation or clarification phase preferably occurs in the existing animal wastewater treatment lagoon.

  • Publication number: 20020032931
    Abstract: An apparatus and method for using a dry cleaning machine to clean laundry that reduces environmental impacts by the substitution of ozone for the hazardous solvents traditionally used in the dry cleaning washing process. The apparatus and method for dry cleaning includes the steps of filtering the water whereby any debris present in the water is removed, measuring the dissolved ozone concentration of the water, recirculating the water between the tank and the water purifier until a desired ozone concentration is realized ensuring that the desired dissolved ozone concentration of the water is attained prior to the start of the cleaning process and continuously recirculating the water through the dry cleaning washing machine, the water purifier, and the tank during the cleaning process.

The apparatus and method of the present invention may be readily sized and configured depending upon the amount and constituent(s) of the wastewater to be treated. In a first embodiment, the apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or spray irrigated. In use, the apparatus and method of the first embodiment may actually require addition of make-up water during periods of low rainfall to make-up water losses due to evaporation and drift. It is contemplated that the only byproduct of the apparatus and method of the first embodiment may be a beneficial sludge if a sufficient number of installations are operated.

  • Patent number: 6090294
    Abstract: An apparatus and method for the purification of contaminated water whereby the contamination level of the wastewater is automatically monitored and treatment self-adjusted and continued until the desired level of purification is reached. Specifically, if upon treatment a pre-set purification level is not obtained a water recycle control means completely precludes the uptake of additional contaminated water and recycles wastewater within the apparatus until the desired level of purification is obtained.

  • Patent number: 6039874
    Abstract: An apparatus and method for treating and reusing the wastewater discharged from agricultural animal farms. The apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or spray irrigated. The wastewater effluent is first passed through a mechanical screen were bulk solids are separated and partially de-watered. The screened effluent is then directed to a primary plastic-lined earthen lagoon where it undergoes aerobic digestion utilizing specially selected bacteria. After treatment in the primary lagoon, the wastewater effluent is used to wash the floors of the hog houses or undergoes a purification phase including solids separation/denitrification, filtration and sterilization. The solids separation/denitrification phase (clarification) preferably takes place in an anoxic environment in preferably above-ground tanks where suspended solids removal will occur as well as denitrification for nitrate reduction.

  • Patent number: 5785864
    Abstract: An efficient, economical, portable, movable, and compact apparatus and method for treating a fluid with ozone comprising multiple pressurized contact columns which are arranged in a hybrid parallel and series column configuration, which utilizes a unique control system and piping arrangement to improve the efficiency of the mass transfer of ozone into the water and increase its solubility by increasing the contact time between the water phase and the gas phase.

  • Patent number: 5632904
    Abstract: Metal-ligand complexes produced by coordination chemistry for use as a biocide and a method for detoxifying water or effluent are disclosed. Metallic biocides are bound with acceptable complexing agents as a type of coordination compound to shield the metal ions from other reactants in the water supply being treated while keeping the metal ions available for biocidal action. In particular, pre-mixed solutions of metal-ligand complexes are added as a disinfectant to water containing ions such as calcium, iron, carbonates, chlorides, nitrates, phosphates, and sulfates.

  • Patent number: 5607653
    Abstract: A process and apparatus for treating and detoxifying salts-hydroxides scrubber wastes containing nitrite salts or sulfite salts so that the final product has low nitrite or sulfite content, a neutral pH and is usable either as a base blend or as a stand-alone liquid product for agricultural applications. One approach is to have a continuous flow oxidation of the waste solution by ozone followed by a neutralization step with MKP. Another approach is to perform oxidation and neutralization in one step by the addition of hydrogen peroxide and MKP.
