Publication number: 20110174743Abstract: Compositions, methods of making the compositions, systems, and processes for treating a fluid containing a contaminant are presented. The treatment reduces the concentration of contaminants, such as such as toxic metals, metalloids, oxyanions, and dissolved silica. The reduction in concentration of a contaminant may be sufficient so as to effect remediation of the fluid with respect to the contaminant. The treatment may reduce the concentration of a plurality of contaminants. The composition typically includes zero-valent iron, an iron oxide mineral, and ferrous iron. The ferrous iron promotes maintenance of the iron oxide mineral. The iron oxide mineral may, in turn, promote the activity of the zero-valent iron.

Publication number: 20110042286Abstract: This is a water cleansing system intended for very low technology primitive communities buildable for between $600 and $1,000 of parts with labor extra.

Publication number: 20100176055Abstract: In a method for removing sulphate and heavy metals from waste water: a) in a first treatment step (I) hydrogen sulphide is guided through the waste water, heavy metals that are present in the waste water are precipitated as sulphide, and are removed from the waste water, b) in a second treatment step (II), calcium sulphate is precipitated from the waste water by adding a precipitation auxiliary agent, c) the calcium sulphate is removed in the second treatment step (II) and one part thereof is guided to a third treatment step (III) in which sulphate is converted into hydrogen sulphide with the aid of sulphate-reducing bacteria, d) hydrogen sulphide formed in the third treatment step (III) is guided back to the first treatment step (I).Type: ApplicationFiled: August 10, 2007Publication date: July 15, 2010Inventor: Michael Riebensahm

Patent number: 7749380Abstract: An integrated and modular infrastructure resource system (IRS) is herein described. The IRS includes one or more infrastructure modules adapted to fulfill a given infrastructure needs such as electrical power, communications, water purification, and air filtration. The IRS may be controlled locally by a control module coupled to the infrastructure modules by a power bus and a control bus or remotely by a remote control-panel that communicates with the IRS by means of a communications module that includes a two-way communications device. The power bus and control bus act to network all of the provided infrastructure modules into an integrated system. Maintenance and logistics for a plurality of IRS's may be managed remotely by a single remote control panel.Type: GrantFiled: December 8, 2004Date of Patent: July 6, 2010Assignee: Erbus, Inc.Inventors: Deborah Yungner, Frank G. Mendez, David J. Peterson

Patent number: 7736522Abstract: A sanitizer generation system supplies power to a first and a second sanitizer generator. Each of the sanitizer generators is connected to a body of water by a circulation system. The system includes a power supply and a control system connected to the power supply and the sanitizer generators. The control system selectively delivers electric current from the power supply to the first and second sanitizer generators.Type: GrantFiled: June 29, 2009Date of Patent: June 15, 2010Assignee: Ecolab Inc.Inventors: Patrick H. Kilawee, Clyde A. Bailey, Leonard J. Kadlec

Patent number: 7736494Abstract: An ozone delivery system for delivering and manufacturing a measured amount of an ozone/oxygen admixture, which is able to measure, control, report and differentiate between delivered-ozone and absorbed-dose of ozone. Improved gas-fluid contacting devices that maximize gas-fluid mass transfer may be included. All gas contacting surfaces of the system, including one or more gas-fluid contacting devices are made from ozone-inert construction materials that generally do not absorb ozone or introduce amounts of contaminants or deleterious byproducts of oxidation into a fluid or non-fluid target from ozone oxidation.Type: GrantFiled: October 11, 2004Date of Patent: June 15, 2010Assignee: AcquiSci, Inc.Inventors: Joseph S. Latino, Steven A. Keyser
