  • Publication number: 20020096472
    Abstract: There is provided a process for treating industrial wastewater that substantially eliminates the generation of excess solids in the system requiring mechanical removal. The wastewater undergoes an equalization step wherein hydraulic flow is smoothed and the pH of the wastewater is adjusted to near neutral pH conditions. The equalized wastewater is then transferred to aeration tanks where the organic process wastes are absorbed, metabolized, or otherwise biodegraded by the microorganisms in the mixed liquor in the aeration tanks. After the aeration step, the wastewater is separated by gravity in a clarifying step to separate the wastewater into a liquid phase and a semi-solid phase. The clarified liquid phase is withdrawn from the clarifier and discharged, while the semi-solid phase is transferred either directly back to the aeration/biological treatment step, as recycle-activated sludge, or into a bioreactor as waste-activated sludge. In the bioreactor the semi-solid phase is subjected to active aeration.

  • Patent number: 6418384
    Abstract: Apparatus and method for monitoring acoustic emission signals in machinery that processes solid material such as aspirin to detect rubbing conditions. The apparatus includes an acoustic signal processing system having a computer, an acoustic signal processing program capable of configuring the computer as a filter, and a rubbing signal identifier that configures the computer to set filter conditions for the filter and to detect a rubbing signal. The filter conditions remove some operating noise having a hit rate higher than the operating rate of the rotating part of the machinery by excluding amplitudes less than a front end filter threshold amplitude and durations less than a front end filter duration. The rubbing signals are detected according to the criteria: intensity greater than a predetermined intensity, acoustic emission activity greater than the operating rate of the rotating part and signal length greater than a predetermined signal length.

  • Patent number: 6376631
    Abstract: The present invention relates to processes for making polymers from at least one tertiary amino-containing monomer and at least one vinyl-functional monomer, while controlling residual monomers and avoiding production of Michael addition adducts. The process employs one or more of the following steps to avoid such adducts, maintaining at least one tertiary amino-containing monomer and at least one vinyl-functional monomer separate until the polymerization reaction, maintaining the at least one tertiary amino-containing monomer and at least one vinyl-functional monomer free of water until the polymerization reaction, and employing high temperatures for the polymerization reaction. The polymers are useful in personal care products, fabric detergent, hand dishwashing detergent, oil well treating chemicals, fire-fighting foam, agricultural chemicals, flocculants, coagulants, and household cleaners.

  • Patent number: 6375969
    Abstract: This invention relates to certain natural diatomaceous earth granule compositions which can be broadcast, i. e., dry spread on the soil to deliver a pesticide or fertilizer. The granules retain their physical integrity when spread, and have the unique property to spontaneously disintegrate when irrigation water is applied or rainfall hits the particle. Upon wetting, the particle disintegrates (blooms) to cover the soil surface. This bloom can cover an area many times the original area covered by the granule. The granules have high loadings of the diatomaceous earth, i.e. from about 35 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent disintegration; rewetting and binding properties. Bioactive compounds can be loaded at up to 60 weight percent of the granule. Bioactive compounds may be formulated products or technical grades and may be homogeneously distributed throughout the granule or spray impregnated onto the granule.
