Direct CO2 Gas Injection The direct gas injection method of pH control is the traditional method for most water plants. The CO2 gas is injected through a very fine bubble diffusion assembly which is located in a basin with a minimum water depth of 10 feet. Through a series of baffles in the basin, the CO2 bubbles are kept in submergence as long as possible. The use of a mechanical mixer located over a CO2 diffusion system is another choice for the addition of CO2 gas. The system uses a TOMCO storage unit and vaporizer for maximum system quality. The direct CO2 gas feed pH control system is available in the following control configurations: 1. Manual pH Control: The CO2 gas injection in controlled by a manual valve. 2. Automatic pH Control: The CO2 gas injection is controlled by a backfeed pH signal. 3. CO2 Flow Paced Control: The CO2 gas injected based on a predetermined CO2 per gallon requirement. 4. Water Flow Paced Control not recommended. The Direct CO2 Gas Injection system has, just like our patented Pressurized Solution Feed System system, an excellent track record for solving potable water and waste water problems. Our experts will gladly answer any questions you desire if you contact TOMCO.
