Water Treatment |
Linde's environmental solutions can be found throughout the water cycle, from drinking water and wastewater to ponds, lakes, and streams. Linde's SOLVOX® equipment series efficiently dissolves gases in various applications during water treatment.
Oxygen is one such gas. The microorganisms used in biological sewage treatments need oxygen to “breathe.” The SOLVOX® process introduces pure oxygen into wastewater, as needed, considerably enhancing the cleaning efficiency of sewage-treatment plants.
Nitrogen compounds that do not degrade in sewage-treatment plants cause excessive algae growth and temporarily deplete oxygen levels in surface waters. The SOLVOX® process helps restore the self-cleansing power of waters and thus protect fish-stock depletions.

| A number of Linde gases are used in wastewater treatment:
· Oxygen: In biological wastewater treatment, microorganisms need oxygen to “breathe.” Pure oxygen is preferred over air for improving aerobic activity, increasing DO levels, and reducing unpleasant odors in wastewater plants. Oxygen is used in overloaded purification plants, to enhance existing processing facilities and eliminate the need for costly expansions.
Oxygen can also prevent the formation of hydrogen sulfide in buffer tanks, lagoons, piping, and sewer systems, thus controlling odors and eliminating pipe corrosion and maintenance downtime.
· Ozone: Treating discolored waters or chemical effluent with ozone can ensure compliance with legislative COD requirements.
· Carbon dioxide: is a safer and environmentally friendlier alternative than sulfuric acid for pH control; it can also buffer the wastewater to a pH of 6.5, eliminating the possibility of overdoses that can overly reduce the pH.

Most municipal drinking-water plants still use chlorine for disinfection, but ever-tightening EPA rules—i.e., reducing trihalomethane levels and eliminating Giardia and Cryptosporidium cysts—will render chlorine virtually useless.
Ozone is fast becoming the disinfection agent of choice, as it produces truly odorless and tasteless drinking water. Oxygen, when used instead of air as a feed source to an ozone generator, can greatly increase the ozone concentration of an existing generator, or reduce the size of a new one.

Streams, ponds and lakes.
Fish deaths from massive algae growth—caused by the eutrophication of rivers and lakes—can be avoided with controlled oxygenation. Through the safe use of CO2 and improved process controls, permissible pH limits can be safely and accurately achieved.
Linde can help you optimize your oxygenation and process procedures and improve your bottom line, while keeping our streams, ponds and lakes clean. Call us at 1-800-755-9277 or contact a Linde customer representative. |
