Retrofit Brush Rotors With Disc Aerators: Increase Capacity And Performance
When brush rotors approach their useful life, a prudent upgrade option is to replace them with Disc Aerators from Siemens. Existing tanks can be used. Disc Aerators allow for improved mechanical efficiency, simpler operation, and lower energy and maintenance costs. Their rugged, durable plastic design is lightweight and compatible with existing structures, and does not require baffles or additional mixing equipment for oxygen transfer. The Siemens product is proven and backed by four decades of installation expertise.
Disc Aerators are ideal for both single and multichannel ditches. Siemens has recently introduced a torque tube configuration for wide ditch applications to expand the number of plants that can upgrade to Disc Aeration. Plants with multiple ditches in series provide the perfect opportunity for an upgrade that also supports simultaneous nitrification/denitrification for improved nutrient removal performance.
