This flow diagram begins with a truck weighing in empty at the Acid Recovery Facility. The truck picks up a tanker load of spent acid from a customer and weighs back in. Alternatively, the spent acid may be obtained on site. A sample of spent acid is sent to the on-site laboratory. The entire batch is then pumped to a storage tank in the tank farm.

When the facility is ready to process a batch of acid, it is pumped from the storage tank where it has been settling to filter out gross particles. The solution enters our Acid Recovery System where water and acid are recovered. The ferrous chloride, removed as a slurry, is concentrated into crystal form and trucked to various markets.
