In-tank recirculating arsenic treatment system

Patent Brady, Patrick V [Albuquerque, NM]; Dwyer, Brian P [Albuquerque, NM]; Krumhansl, James L [Albuquerque, NM]; ...

A low-cost, water treatment system and method for reducing arsenic contamination in small community water storage tanks. Arsenic is removed by using a submersible pump, sitting at the bottom of the tank, which continuously recirculates (at a low flow rate) arsenic-contaminated water through an attached and enclosed filter bed containing arsenic-sorbing media. The pump and treatment column can be either placed inside the tank (In-Tank) by manually-lowering through an access hole, or attached to the outside of the tank (Out-of-Tank), for easy replacement of the sorption media.

Method and apparatus for energy efficient self-aeration in chemical, biochemical, and wastewater treatment processes

Patent Gao, Johnway [Richland, WA]; Skeen, Rodney S [Pendleton, OR]

The present invention is a pulse spilling self-aerator (PSSA) that has the potential to greatly lower the installation, operation, and maintenance cost associated with aerating and mixing aqueous solutions. Currently, large quantities of low-pressure air are required in aeration systems to support many biochemical production processes and wastewater treatment plants. Oxygen is traditionally supplied and mixed by a compressor or blower and a mechanical agitator. These systems have high-energy requirements and high installation and maintenance costs. The PSSA provides a mixing and aeration capability that can increase operational efficiency and reduce overall cost.

Tunable, self-powered integrated arc plasma-melter vitrification system for waste treatment and resource recovery

Patent Titus, Charles H [Newtown Square, PA]; Cohn, Daniel R [Chestnuthill, MA]; Surma, Jeffrey E [Kennewick, WA]

The present invention provides a relatively compact self-powered, tunable waste conversion system and apparatus which has the advantage of highly robust operation which provides complete or substantially complete conversion of a wide range of waste streams into useful gas and a stable, nonleachable solid product at a single location with greatly reduced air pollution to meet air quality standards. The system provides the capability for highly efficient conversion of waste into high quality combustible gas and for high efficiency conversion of the gas into electricity by utilizing a high efficiency gas turbine or by an internal combustion engine.
