To enhance the performance of the Tow-Bro® Sludge Removal System, Siemens offers a Flocculating Energy Dissipating Well Arrangement (FEDWA) baffle system.  The FEDWA baffle system is a simple, practical method of disspating inlet energy and enhancing flocculation in primary and secondary clarifiers.  

• Rapid sludge removal and efficiency - Over a full range of flows means a fresher sludge, less chance for septicity, reduced aeration requirements, and prevention of phosphate release.
• Maximum solids concentration - Less required pumping means that aeration basins and solids handling systems can be designed and operated for the minimums.  
• Minimum sludge irritation - Achieved through a gentle removal action and a minimum of underwater disturbance.
• Balanced hydraulic design - Removes settled solids in proportion to the area covered over a wide range of flows and permits low sludge blankets to be maintained for cleaner effluents.
