Gas In Your Business for Environmental Industry

Oxygen (O2)
Ozone is used for drinking water treatment, in particular when alternatives, such as chlorine, are undesirable.
In the biological treatment of waste-water, the use of oxygen instead of air permits increased capacity in existing treatment plants.  Mixing oxygen into sewers reduces hydrogen sulfide formation, which results in reduced corrosion and odor.

Carbon dioxide (CO2)
Used as a propellant in aerosol cans, it replaces more environmentally troublesome alternative. Greenhouses have shown that by using carbon dioxide production yields can increase by 20%.  A typical carbon dioxide level would be about 1000 PPM (parts per million).
By using dry ice pellets to replace sandblasting when removing paint from surfaces, problems of residue disposal are greatly reduced. It is also used to neutralize alkaline water.

Hydrogen (H2)
Hydrogen is mixed with inert gases to obtain a reducing atmosphere, which is required for many applications in the metallurgical industry, such as heat treating steel and welding.  It is often used in annealing stainless steel alloys, magnetic steel alloys, sintering and copper brazing.
