Plant for the treatment of water from flooding of a uranium mine
Description of the plant
As part of the remediation of the WISMUT GmbH the mine at Schlema-Alberoda was decommissioned and a controlled flooding was carried out. The excess mine water contains dissolved uranium, arsenic and manganese. Also radium is found in the water. For discharging into the local river EnviroChemie has built a water treatment plant. This plant is designed for a capacity of 450 m³/h.
The water treatment consists mainly of a combination of precipitation followed by flocculation, sedimentation and filtration. Uranium is bound and precipitated by using Gopur® 3000, a special organic product.
The resulting sludge is mechanically dewatered and immobilized. The immobilized product fulfills the mechanical and chemical criteria for deposition.
The plant works fully automatic and visualized. All components of the water line are 100% redundant.
