Biogas Production
In wastewater treatment, sludge from activated tanks is processed in digestion towers to create biogas. Mixing the sludge thoroughly improves gas output and reduces how long it needs to stay in the reactor.
- Gas is collected from the top of the tower.
- It’s compressed and re-injected at the bottom to enhance mixing.
- This process helps generate more biogas while improving efficiency.
Digester Gas Compression
Special compressors use a liquid ring to cool the gas during compression, keeping the system almost at room temperature.
- Protects sensitive parts like valves, burners, and motors.
- Lowers maintenance costs and extends equipment life.
- Acts as a built-in flame arrestor, improving safety.
- Cleans and partially dries the gas for reuse in the treatment process.
Fish and Pond Aeration
Increasing oxygen in pond water helps fish grow faster and in larger numbers. This is achieved using gas ring blowers or liquid ring pumps.
- Air is pulled from the atmosphere.
- It’s pushed into the water through fine bubble diffusers.
- The released oxygen improves water quality and supports fish health.
Fish Farming (Aquaculture)
In fish farming, pneumatic systems feed the fish using soft pellets that need careful handling.
- Side channel blowers with variable speed drives gently move the pellets.
- Reduces pellet damage and feed waste.
- Saves space – takes up only 25% of traditional systems.
- Low noise, minimal vibration, and low maintenance requirements.
Gasoline Vapour Recovery
During refueling, gasoline vapours are collected to prevent harmful air pollution.
- Pressure sensors detect when to activate the compressor.
- Vapours are pulled into a scrubber system.
- Recovered liquid is returned to the fuel system.
- Vapours are recompressed and reused in the evaporator loop.
- Helps prevent ground-level ozone and toxic emissions.
Hydroexcavation
This technique uses high-pressure water and industrial vacuum to dig soil safely and cleanly.
- Breaks up soil with pressurized water.
- Soil and water slurry is vacuumed into a debris tank.
- Ideal for sensitive utility excavation and minimal surface damage.
Landfill Gas Recovery
As waste decomposes in oxygen-free environments, it produces landfill gas.
- Gas is collected and compressed using gas blowers or compressors.
- It can be used as heating fuel, converted to electricity, or liquefied.
Soil Gas Extraction
This process removes harmful gases from polluted soil, such as hydrocarbons.
- Side channel blowers extract gas depending on soil type and pollution level.
- Effective range is typically between 10 and 80 meters.
- Exhaust air must be treated per air quality regulations.
Solar Lamination
Laminating solar panels involves vacuum processes to ensure clean, bubble-free adhesion.
- Air is removed from the laminator chamber using vacuum.
- Polymer layers are then heated and bonded under vacuum conditions.
