When water treatment plant operators and consultants across India need reliable, corrosion-resistant, high pressure air handling solutions for their critical processes, they turn to Shivam Engineering & Fabrication. As a leading high pressure blower manufacturer for water treatment plants, we have supplied hundreds of units to municipal sewage treatment plants (STPs), industrial effluent treatment plants (ETPs), and water treatment plants (WTPs) across the country. Our high pressure blowers are engineered for durability, corrosion resistance, and continuous operation – perfectly suited for the aggressive environments of water and wastewater treatment.
Why Water Treatment Plants Need High Pressure Blowers
Water and wastewater treatment plants require high pressure air for filter cleaning, membrane scouring, and aeration processes. Our specially designed high pressure blowers feature:
- High Pressure Capability – Up to 1,200+ mmWC for filter backwash and MBR applications.
- Corrosion-Resistant Construction – SS304 or epoxy-coated MS for chemical resistance.
- Oil-Free Air Delivery – No contamination risk for biological treatment processes.
- Low Noise Operation – Precision-balanced impellers for quieter operation (75-85 dB).
- Low Maintenance – Designed for continuous 24/7 operation.
- VFD Ready – For variable flow control and energy savings.
Key Applications of High Pressure Blowers in Water Treatment
1. Filter Backwash Air Scour
High pressure air for scouring rapid sand filters, dual-media filters, and activated carbon filters during backwash cycles. Air scour agitates the filter media, releasing trapped solids for removal. Pressure range: 500-1,000 mmWC depending on media depth (typically 1-2 meters).
2. MBR (Membrane Bioreactor) Scouring Air
High pressure air for scouring/agitation of membrane modules in MBR systems to prevent fouling and maintain membrane permeability. Requires consistent, oil-free air at 500-1,200 mmWC pressure.
3. Grit Chamber Aeration
Air supply to grit chambers in preliminary treatment to prevent organic solids from settling with grit. Pressure range: 300-600 mmWC depending on diffuser depth.
4. Anaerobic Digester Gas Recirculation
High pressure blowers for recirculating biogas or compressed gas for mixing in anaerobic digesters. Pressure range: 500-1,000 mmWC.
5. Air Lift Pumping for Sludge Transfer
High pressure air for air lift pumps to transfer sludge between process tanks or to dewatering equipment. Pressure range: 500-1,000 mmWC depending on lift height.
Working Principle – High Pressure Centrifugal Blower
High pressure centrifugal blowers use a high-speed impeller with backward-curved blades to generate significant static pressure. Air enters axially through the inlet, is accelerated radially by the impeller, and is then discharged through a scroll housing. The high rotational speed and precision impeller design enable pressure generation up to 1,200+ mmWC, making them ideal for filter backwash, MBR scouring, and other high pressure water treatment applications.

Filter Backwash Air Scour – Detailed Application
Filter backwash air scour is a critical process in water treatment plants for cleaning rapid sand filters, dual-media filters, and activated carbon filters. Key considerations include:
- Pressure Requirement: For every 1 meter of media depth, approximately 100-150 mmWC pressure is required. For 1.5 meters media depth: 600-800 mmWC. For 2 meters media depth: 800-1,000 mmWC.
- Air Flow Requirement: Typically 2-5 CFM per square foot of filter area during air scour phase.
- Operating Cycle: Air scour typically operates for 2-5 minutes per backwash cycle, 1-2 times per day.
- Oil-Free Air Required: Oil contamination can damage filter media and cause taste/odor issues in treated water.
MBR Scouring Air Application
In Membrane Bioreactor (MBR) systems, scouring air is essential to prevent membrane fouling. Key features include:
- Continuous Operation: MBR scouring blowers must operate 24/7 while the MBR is running.
- Pressure Range: 500-1,200 mmWC depending on membrane module depth and type.
- Air Flow Rate: Typically 5-15 m³/h per m² of membrane area (3-9 CFM per ft²).
- Oil-Free & Clean Air: Oil contamination will permanently damage membrane pores.
- Low Noise: MBR plants are often located near residential areas, requiring low noise operation.

Frequently Asked Questions – High Pressure Blower for Water Treatment
1. What pressure is required for filter backwash air scour?
For filter backwash air scour, the required pressure is approximately 100-150 mmWC per meter of media depth. For typical 1.2-1.5 meter media depth, 600-850 mmWC is required. Additional allowance for piping and diffuser losses should be included.
2. Can your high pressure blowers be used for MBR scouring air?
Yes. Our high pressure blowers are ideal for MBR scouring air applications, providing oil-free, corrosion-resistant air at the required pressure (500-1,200 mmWC) and continuous 24/7 operation.
3. What is the difference between aeration blower and a high pressure blower?
Aeration blowers typically operate at lower pressure (200-500 mmWC) for diffused aeration in biological tanks. High pressure blowers (500-1,200+ mmWC) are used for filter backwash, MBR scouring, and other applications requiring higher pressure to overcome media or membrane resistance.
