San Antonio Water System Installs Activated Carbon Units

Dual-vessel skid systems help minimize formation of disinfection byproducts

Three TIGG Corp. activated carbon dual-vessel skid systems went online in San Antonio, Aug. 14, 2013. The systems are capable of purifying more than 5 million gal of water per day. The integrated units were engineered at TIGG's Oakdale, Pa. headquarters and built at its Heber Springs, Ark. facility.

The granular activated carbon adsorption systems are being used to proactively remove total organic carbon and trihalomethanes from Canyon Lake, a nearby potable surface water supply, to reduce the potential for formation of disinfection by-products (DBP) in the distribution system, and ensure compliance with U.S. Environmental Protection Agency Stage 2 disinfection byproduct regulations.

TIGG won the competitively bid contract to rent the units to the San Antonio Water System (SAWS) on July 3. The agreement could be worth up to $2.5 million and includes spent carbon exchange and disposal services. TIGG's CP 20K-10 dual Vessel Skid Systems meet or exceed SAWS specification requirements for the application. The units are capable of running either in series or parallel. Each system holds 40,000 lb of granular activated carbon and is capable of purifying water at 1,500 gal per minute. The contract also included operational training for SAWS employees.

"Although we've been manufacturing the dual-vessel CP 20K-10 system for years, this is the first time we've supplied a client with the complete system on a skid," said Anthony Mazzoni, TIGG vice president. "We specifically engineered each skid to ship on a single flatbed truck. Plus, the skids simplify the setup process and help reduce labor costs."
