TIGG - Per- and Poly-Fluoroalkyl Substances (PFAS) for Treating the Contaminants

Our water-purification systems, the TIGG Series of CP units, along with our granular activated carbon media are currently removing PFOA and PFOS contaminants from municipal drinking water to non-detectable levels. When operated in a series   ow pattern, our systems will provide 100% redundancy to ensure a safe water supply.

Our dual-vessel activated carbon systems are ideal for municipalities looking to upgrade current capabilities to meet the challenges of complying with state and federal regulations. The back washable CP systems hold up to 40,000 lbs per vessel of activated carbon and have   ow rates up to 1,000 gpm.

Ion exchange has proven to be a meaningful process for removing the short-chain compounds of PFAS using a selective resin. TIGG integrates resin into the process as a stand-alone or as a polishing process when the water quality is suitable.

No water from two locations is exactly the same. Rapid Small Scale Column Tests (RSSCT) can assist in predicting life expectancy and performance properties when comparing several types of GAC. The testing requires weeks, rather than months to perform and can be included for most state review and acceptance requirements.

Activated carbon is a material that is produced from carbonaceous source materials, such as coal, coconuts, nutshells, peat, wood, and lignite. The primary raw material used for activated carbon is any organic material with a high carbon content. The carbonbased material is converted to activated carbon through physical modification and thermal decomposition in a kiln, under a controlled atmosphere and temperature. The finished product has a large surface area per unit volume and a network of submicroscopic pores where adsorption takes place.
