Patent number: 11370678Abstract: Methods of treating bodies of water or wastewater are disclosed herein. The method can include providing one or more water treatment compositions comprising a compound with a peroxide group or a carbonate salt, a binder, a fibrous material, and an inert material, where the compound, binder, the fibrous material, and the inert material are combined into the form of an integral product, and immersing the integral product into a body of water or wastewater. The method can include a dispensing apparatus for holding such integral products such that the step of immersing the tablets into a body of water or wastewater is accomplished by immersing the dispensing apparatus into the body of water or wastewater. The dispensing apparatus can be arranged such that when integral products are placed in the apparatus the integral products form a vertical column.Type: GrantFiled: August 3, 2020Date of Patent: June 28, 2022Inventors: Jan D. Graves, Gregory D. Graves

Patent number: 10870589Abstract: A filter system for filtering a fluid stream is disclosed herein. The filter system includes a first fluid passage, a first chamber, a second chamber, an adsorbing media, and a second fluid passage. The first fluid passage is arranged such that a fluid stream can flow through the first fluid passage and into the filter system. The first chamber is arranged to hold suspended or dissolved solids, pollutants, and nutrients that are filtered from the fluid stream. The second chamber is positioned above the first chamber and in fluid communication with the first chamber. The adsorbing media is positioned in the second chamber. The second fluid passage is arranged such that filtered fluid from the fluid stream can flow out of the filtering system through the second fluid passage.Type: GrantFiled: April 27, 2016Date of Patent: December 22, 2020Inventors: Jan D.

Patent number: 10730769Abstract: Compositions for treating bodies of water are disclosed herein. The water treatment composition can include sodium percarbonate, a binder, a fibrous material, and inert materials combined to form an integral product. The integral product can be in the form of a tablet. The binder can be vinylpyrrolidone-vinyl acetate copolymer, the fibrous material can be organic fibers, for example cotton fibers, and the inert material can be polyethylene glycol. The integral product can be between approximately 70 to 95 weight percent sodium percarbonate, between approximately 0.5 to 10.0 weight percent binder, between approximately 0.05 to 10.0 weight percent fibrous material, and between approximately 1.0 to 10.0 weight percent inert material. More specifically, the integral product can be approximately 91 weight percent sodium percarbonate, approximately 4.5 weight percent binder, approximately 1.0 weight percent fibrous material, and approximately 3.5 weight percent inert material.Type: GrantFiled: February 10, 2017Date of Patent: August 4, 2020Inventors: Jan D.

Patent number: 7691272Abstract: A method of effecting efficient flow equalization in a settling and retention basin having a peripheral wall housing a removable design flow equalization port and a filter member exteriorly of the peripheral wall by (a) observing the height of liquid level induced during wastewater flow upon the filter member relative to the flow equalization port. Thereafter (b) determining whether the observed height of step (a) is outside a desired optimum height range reflective of meeting the design flow characteristics of the design flow port. Thereafter (c) replacing the design flow equalization port with a different size flow equalization port based upon the performance of step (b).Type: GrantFiled: August 18, 2008Date of Patent: April 6, 2010Inventor: Jan D. Graves
