Issue
In Gorno-Altaysk WWTP, instead of mechanical sludge dewatering, sludge was dewatered in outdated sludge drying beds. Malodor from sludge drying beds disturbed residents from nearby leaving area, therefore regional authorities made a decision to fund the construction of a new sludge dewatering facility.
Solution
Based on national requirements, 3 units (2 duty and 1 stand-by) of MDQ-352 C were installed.
