Meeting the aforementioned levels of trichloropropane in drinking water is an expensive challenge to most water utilities. While some studies have attempted to demonstrate in situ treatment, the most reliable and prevalent means of removing TCP is pump and treat through Granular Activated Carbon (GAC).
Evoqua Water Technologies is unique in that we offer a comprehensive range of activated carbon, equipment, and services, which can be utilized to meet water utilities needs for compliance. With regard to GAC products, Evoqua offers the most comprehensive menu the market has to offer.
Our approach starts by evaluating the most effective base material for each application to ensure maximum efficiency. AquaCarb® CX enhanced coconut shell GAC combines the benefits of an activated carbon with a high micropore structure of coconut shell GAC and faster kinetics of a bituminous coal. The result is an excellent capacity for difficult-to-adsorb organics as well as adsorptive performance for other background organics. The result is longer bed life and lower life cycle costs.
The AquaCarb family of carbons are ANSI/NSF 61 classified for use in potable applications. They fully conform to the physical, performance and leachability requirements established by ANSI/AWWA B604, including Food Chemical Codex.
For more than 40 years, Evoqua Water Technologies has been active in treating groundwater for the removal of organic and inorganic impurities. We were one of the first companies to provide remediation of impacted waters with the development of our activated carbon treatment packages for the removal of trichloroethylene (TCE). Since then we have worked with water districts, impact communities, and industry in the removal of both organic compounds, including TCE, TCP, H2S, and inorganic contaminants including, arsenic, chrome, lead, perchlorate, and nitrate. Whether you are treating groundwater water to meet discharge standards or drinking water standards, Evoqua has a solution.
What sets Evoqua apart is the broad range of technologies we offer as well as the services we provide. With each technical solution, Evoqua Field Engineers are available to help set up, start up, or even operate the equipment. Since we are able to draw from a spectrum of solutions, we can identify the answer that will provide you the best overall value.
In addition to media and services, Evoqua provides treatment equipment. Treatment vessels specifically designed for these types of applications are available for either purchase or rent. The vessels can operate over a wide range of pressures with capacities from 5 to 2,000 GPM. Standard features include:
- An optimized underdrain system for lower pressure drops.
- Durable, quality construction with 100% internally/externally welded seams.
- Abrasion and corrosion resistant internal epoxy coatings.
- Top and side manways that permit easy access and inspection of the underdrain system.
