  • Patent number: 6149821
    Abstract: A balanced water purification system is provided with a buffer compound, and oxidizer/clarifier compound, and a biocide compound disposed in multiple packets such that the biocide compound and the oxidizer/clarifier compound are contained in different packets. The composition purifies and clarifies water while maintaining the existing water pH. The composition may also include a filtration aid, an algicide, a calcium releasing source, a chelator, and a sequestering agent.

  • Patent number: 4975199
    Abstract: The invention relates to a process of reclaiming deionized water from waste water contaminated with particulate materials, detergents, biological and/or radioactive materials, comprising the steps of:a. passing the waste water through one or more particulate filters to remove the particulate materials;b. directing the effluent from the particulate filter(s) through a first reverse osmosis filter to generate purified water essentially free of detergents, biological and radioactive contaminants and bypass water contaminated with the impurities removed from the effluent; andc. removing ions from the purified-free water to generate deionized water.
