Overview
Cloacina’s DRYPAC Aerated Sludge Handling System is engineered to process Waste Activated Sludge (WAS) from various wastewater treatment configurations, including sequencing batch reactors, extended aeration, solids contact clarifiers, and membrane bioreactors.
Sludge Receiving and Aeration
The DRYPAC system receives WAS via either an existing pump or a Cloacina-supplied, pump. The sludge undergoes periodic aeration from a semi-sound-attenuated blower with medium bubble diffusers, which helps prevent sludge stagnation and mitigates odors. This aeration process minimizes manual intervention, ensuring consistent sludge quality and odor control.
Dewatering Process
For dewatering, operators initiate the system manually to configure appropriate settings, after which it functions with automated safeguards to prevent operational issues, including shutdowns for low sludge levels or equipment malfunctions. Pressate from the dewatering process is directed back to the plant’s headworks or to an established disposal area, while dewatered solids are deposited into a client-provided container, such as a dumpster, roll-off, or custom bin.
Integrated Equipment and Control
The DRYPAC package includes all necessary chemical and polymer dosing equipment, integrated into a central control system with remote access capabilities, allowing for monitoring and adjustments from any location. Equipment is arranged for optimal access, supporting ease of operation and maintenance.
Typical Applications
Any producer of liquid sludge desiring to reduce disposal costs through on-site dewatering
