The new sieve bends in the photos below are a typical application of simple yet effective technology. They are designed to separate out the majority of coal from a 1,600US GPM wastewater stream to minimize the number of coal fines entering the site reservoirs. The installation includes a few moving parts or complex electronics. Maintenance consists of routine cleaning out of the overflow and underflow ponds.
This multistage pumping system helps to reduce costly onsite maintenance of existing drainage sludge pits where heavy coal particulate accumulates. These pits were able to be reduced in size and converted to transfer sumps, moving the coal slurry directly to the facility for clarification.
