Fortrans Inc. announces a self-contained pH control and monitoring system that uses CO2 gas to neutralize high pH process water produced at ready mixed concrete plants. The Model 5000S pH Control and Monitoring System offers precise pH control, monitoring of pH and lowers "Total Suspended Solids" of process water contained in pits, settling basins and lagoons. Use of the system will provide clean water to recycle.
The Model 5000S pH Control and Monitoring System offers proven technology to enable operators of ready mixed concrete plants to effectively control the pH and Total Suspended Solids of process water. After the pH is lowered to 7.5 the typical total suspended solids are between 10-18 mg/L without filtration. This enables the facility to meet the pH requirements as well as the 30 mg/L TSS most permits demand before the water can be released. The treated water may be recycled to batch concrete, irrigate rock, rinse the interiors of the drums on the concrete trucks and rinse the exteriors of the trucks as well without staining or scaling of the finishes.
The Model 5000S systems cost 60% to 70% less to operate and maintain than acid-based pH control systems and are also much safer than acid systems. The systems do not require a separate tank and are guaranteed to perform to the owner's satisfaction.
This system has been certified by an independent engineering firm to operate as specified. The units are shipped fully assembled and only require an electrical connection and a supply of carbon dioxide gas plus a C02 regulator.
The system will treat approximately 75,000 gallons over a 24-hour period. The system is also available as a skid mounted unit (Model 5000SK). Higher capacity systems are also available up to 200,000 GPD.
These systems are highly reliable and affordable. Fortrans has a wealth of knowledge of this technology and has saved concrete producers time and money in dealing with high pH process water in an environmentally safe manner. One company in the Boston area will save approximately $250,000 per year in water storage and disposal costs.
