EWAGE TREATMENT AT BAUXITE ALUMINUM PLANTS

Plant producing process consisted of 2 phases:

• Aluminum Ore Mining.
• Processing aluminum ore bauxite into aluminum.

ALUMINUM ORE PHASE

To ensure completely concentrated sludge to be pumped into tailing lake and sewage into the environment, conduct Nalco85035 and Nalco83384 deposition.

ALUMINUM BAUXITE PRODUCTION PHASE

In the process of producing aluminum bauxite, it generates highly alkaline sewage. Much of this waste water will be pumped into the sludge reservoir for storage and reuse.

Fraction escapes into storm water sewer system of the plant.

Processing requirements: 

• Residual water treatment sludge reservoir.
• Adjust the pH of wastewater in rain water drain system.
