Envirogen Launches Compact Coal Mining Water Treatment Product

Water treatment products firm Envirogen Technologies Inc. has launched a new small-footprint fluidized bed reactor system designed to treat low flows of selenium-laden coal mining waters economically and efficiently.

The new system will allow coal mine operators to treat flows that start at less than 100 gallons per minute to lower than 5 micrograms per liter selenium at discharge – even in the presence of high levels of nitrate, the company says.

These systems can be automated and delivered in standard-sized freight containers to difficult-to-reach locations, requiring minimal site preparation and engineering, and can be monitored remotely, Envirogen says.

The small-system, fluidized bed reactor approach aims to allow coal mine operators the ability to treat selected mining water outfalls with a relatively low initial capital expenditure, and the flexibility to relocate the systems to meet changing treatment goals.

APTwater’s ARoTech module used to treat oxidized contaminants in water including selenium, nitrate, perchlorate and chromium (VI) was NSF certified in February.

The ARoTech water treatment process uses hydrogen-fed biological processes to reduce oxidized contaminants.
