NASA Water Treatment System and Oxygen Generation

There are many difficult water treatment problems we all deal with on a daily basis. Few are life and death like this application.

I am on a wide variety of email newsletters. Here was an interesting article on how scientists at NASA's Marshall Space Flight Center (MSFC) are working on taking all available sources of water in a space craft or space station and reclaiming them for reuse. This includes humidity and urine! Overall they achieve 93% recovery of the water.

The name of the project is Environmental Control and Life Support Systems, ECLSS, and is pronounced "EE-cliss".

What is also interesting is they are using part of the water to generate oxygen by electrolysis. In this way, long term mission on the Moon or to Mars can be feasible. In order for this to happen, they need to increase the recovery closer to 100%

New Calcium Carbonate Brochure From Imerys

Imerys Performance Minerals of Roswell, Georgia just released its first brochure for its extensive line of NSF-certified calcium carbonate media for:
- pH adjustment
- Corrosion control
- Remineralization of desalinated water

Many forms of calcite media are available, but not all are safe for use in drinking water. The Imerys media has been tested and certified by the NSF International to NSF/ANSI Standard 60. There are five different NSF-certified grades of calcium carbonate media:
- 40-200(TM) NSF sourced from Marble Hill, Georgia and Sylacauga, Alabama
- 30-50(TM) NSF sourced from Marble Hill, Georgia
- XO White(TM) NSF sourced from Marble Hill, Georgia
- Z White(TM) NSF sourced from Marble Hill, Georgia
- OZ White(TM) NSF sourced from Marble Hill, Georgia

Res-Kem Corp stocks XO White NSF and Z White NSF for immediate shipment. We can provide the other media grades upon request.

We can help you meet these targets.

Dow Introduces Two New Dowex Marathon Ion Exchange Resins

In some industry news, The Dow Chemical Company told us two new products were added to Demineralization price list. These ion exchange resins are Dowex Marathon 650C (H) and Dowex Marathon 550A (OH). These resins are used for polishing mixed beds that do not require nuclear-grade specifications, and where good color differential and excellent separation are required.
