  • Publication number: 20210032146
    Abstract: Compositions, systems, and methods of using alkaline-producing Aluminate salts in the sludge collection and digestion steps of wastewater processing to reduce acidity and/or build alkalinity, reduce hydrogen sulfide release, and reduce phosphate in the effluent.

  • Publication number: 20200095143
    Abstract: A system and method for monitoring and altering the conditions of a sewage system comprising a wet well connected to a sewer. The wet well is also configured to provide sewage to a secondary system, where the sewage is fed into an oxygen contact chamber. That chamber is fed oxygen which is dissolved into the sewage such that the sewage in the contact chamber has elevated oxygen content. That oxygenated sewage is then fed into the sewage system in order to raise oxygen levels and control anaerobic activity. Sensors and valves of the system are controlled by a central controller which provides for improved functionality, energy savings, and automated function.

  • Patent number: 8668779
    Abstract: A method of simultaneously cleaning and disinfecting an industrial water system is described and claimed. The method involves the addition to the water of the industrial water system of a Compound selected from the group consisting of the alkali salts of chlorite and chlorate and mixtures thereof; and an acid, followed by allowing the water in the industrial water system to circulate for several hours. The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. This cleaning and disinfecting method works in a variety of industrial water systems including cooling water systems.

  • Patent number: 8062872
    Abstract: Embodiments described include methods for maintaining the pH and alkalinity during industrial fermentation processes are described that foster optimal microorganism activities throughout the duration of the fermentation process. Magnesium based buffering agents having sufficient buffering capacity and applied at sufficient concentration levels required to neutralize the acidic content of fermentation fluids during the fermentation process cycle are detailed. These magnesium based buffering agents control fermenter processes without causing extreme pH swings to maximize the production of desired fermentation products.

  • Patent number: 7931822
    Abstract: Methods and compositions utilizing aluminum, magnesium, and calcium-based additives for the treatment and neutralization of wastewater are described for removing contaminants from wastewater, including reducing phosphorous-containing compounds, total suspended solids (TSS), biological oxygen demand (BOD), fats, oils, and greases (FOG), and total Kjedahl nitrogen (TKN) are described. Methods and compositions to control pH, sulfur and sodium loads present in wastewater and precipitatable solids are described. Concentrations of aluminum, magnesium, and calcium-based additives are maintained at mass action concentrations to the wastewater component levels present in the wastewater and bracketed approximately +/?0.5 pH units about the pK value of the soluble, buffering species.

  • Patent number: 5384050
    Abstract: A method of removing dissolved oxygen from boiler water having and alkaline pH is disclosed. The method uses at least one hydrazone compound of one of the following formulae: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently selected from hydrogen, C.sub.1 -C.sub.16 alkyl, aryl, substituted alkyl or substituted aryl, and R.sup.5 and R.sup.6 are independently selected from hydrogen, C.sub.1 -C.sub.16 alkyl, aryl, substituted alkyl, or substituted aryl, ##STR2## Preferably, an oxidation-reduction catalyst such as Cu(II) is used as well. The hydrazones used in the present invention are highly shelf stable and do not suffer the toxicity of hydrazine.
