Aeration air supply
Blowers provide air at the flow and pressure required by basin depth, diffusers and the distribution network.
APPLICATIONS · WATER & WASTEWATER
Air, vacuum and fluid transfer for treatment processes.
Aeration, filtration, priming and chemical or sludge transfer are treated as separate duties, each with its own flow, pressure, fluid properties and operating pattern.
TREATMENT PROCESSAir + vacuum + transferDuty-specific technologies
APPLICATION RANGE
Match each treatment duty to its operating point.
Aeration air is selected from oxygen demand and backpressure; filtration and priming depend on wet-gas load; sludge and chemical transfer depend on fluid and material compatibility.
Vacuum filtration
Wet-gas-capable vacuum equipment supports suitable filtration and dewatering duties.
Suction-line priming
Air can be removed from pump suction lines and vessels using a protected vacuum arrangement.
Sludge and chemical transfer
Air-operated diaphragm pumps can handle selected fluids when materials and solids content are compatible.
VACUUM FILTRATION
Separate liquid while managing wet gas and filtrate.
Receiver, separator and moisture-protection arrangements help control filtrate and protect the vacuum source.
SELECTING THE RIGHT SYSTEM
Define air, vacuum and fluid duties separately.
Each process has a different sizing basis and material requirement.

APPLICATION ENGINEERING
The vacuum source is one part of the complete system.
Reliable performance depends on the pump or blower, protection equipment, line arrangement, controls and the real process operating point.
Operating point
Capacity and pressure are checked together at the actual inlet conditions and duty cycle.
Share Operating DataProtection equipment
Filters, separators, condensers, receivers and valves are selected around moisture, particles, liquid carry-over and process risk.
