DryAsh™

DryAsh

AN ADVANCED SOLUTION TO YOUR ASH POND CHALLENGE

If you are a waste administrator at a coal-fired power generation plant, you know that wet fly ash disposal poses significant challenges, including tightening regulatory requirements, costs, storage capacity, service interruptions and environmental concerns. Veolia North America can help. As a leading environmental services provider to the power industry, we are uniquely positioned to provide practical and cost-efficient solutions for ash management.

In an industry that continues to undergo increasing regulatory oversight, Veolia has developed an innovative, practical and extremely effective solution for ash management that is tailored to the specific needs of fossil fuel plants. Our DryAsh™ technology is an advanced ash pond solution that can be either a permanent or temporary inline process that converts wet fly ash to a more workable dry state. Best of all, this turnkey solution can be designed, built and installed within approximately six months of contract approval without any plant or unit shutdowns.

DryAsh™ is an engineered system of tanks, piping, pumps, hydraulic excavation and separations technologies that will be constructed and housed on your plant’s property. Wet, fly ash will be taken from the plant boiler, re-routed away from the ash lagoon and directed into our system, where it's converted to DryAsh™ and transported over land to an on-site landfill or off-site.
