Prevention of swelling sludge
Assisting in balancing the aeration tank
The problem with swelling sludge appears when the microbial balance of the plant has been disturbed and thus the wastewater treatment plant becomes imbalanced. Thus the amount of long-thread bacteria has increased. This usually is a sign of problems in the aeration tank where for example the mechanical aeration may have been targeted incorrectly.
The regular use of the PACS system prevents the forming of oxygen-free spaces, maintains the correct bacterial balance, and prevents the problems with swelling sludge. The PACS system decreases the amount of anaerobic bacteria and creates more living space for aerobic bacterial strains.
If a problem with swelling sludge already exists, the PACS system can be used for performing shock disinfection. It is a one-time operation that can be used for reviving the oxygen-free spaces in aeration tank and to create microbial balance. The shock disinfection of the PACS system eliminates long-thread bacteria causing swelling and thus it normalises the process of wastewater purification. Before the shock treatment the plant’s mechanical operations are inspected and the floating sludge removed. Shock treatment is repeated when required.
