The Solvocarb ® process from Linde North America is an economical way for process industries to neutralize alkaline wastewater with a high degree of control using carbon dioxide. The process injects the inert gas into the process wastewater, and includes the Linde CO2 gas supply and metering system. When dissolved in water, CO2 forms carbonic acid to quickly reduce pH to appropriate levels for discharge. Linde North Americawww.lindeus.com
