Roots Blower for Wastewater Treatment: High-Efficiency Aeration Guide

Biological aeration accounts for up to 60% of total electrical power consumed in Effluent Treatment Plants (ETP) and Sewage Treatment Plants (STP). Choosing a high-efficiency Roots Blower for wastewater treatment is critical for process compliance and cost control.

Why Oil-Free Air is Mandatory for Biological Aeration

Aerobic bacteria inside aeration basins digest organic carbon compounds. If compressor oil enters the air stream, it forms an oil film on membrane diffusers and kills bacterial colonies, halting biological treatment. SAE Roots blowers guarantee 100% oil-free air delivery.

Twin Lobe vs Tri Lobe for Wastewater Aeration

• Twin Lobe Roots Blowers: Robust, economical, and ideal for standard continuous aeration duty.
• Tri Lobe Roots Blowers: Lower pressure pulsation, reduced noise, and gentler on fine-bubble diffuser membranes.

Acoustic Noise Control Compliance

STPs located near residential townships require low ambient noise. Installing an Acoustic Hood Blower Package keeps sound levels well below 75 dB(A) at 1 meter.
