There are many industries in which products can be used to improve our environment. In environmental applications, ventilation is a very necessary process. For example, vacuum pump applications: gas compression, material collection, ventilation.

 

Application of vacuum pump in environmental protection industry: waste water treatment, biogas compression, vacuum water addition, waste water purification/activated sludge tank oxidation, gas recovery (biological gas), oil and gas recovery.

 

Wastewater treatment

Vacuum pumps provide the suction pressure needed to drain the waste water and to clean the sewer network.

 

Methane gas compression

The liquid ring pump pulls the methane from the top of the tank and recirculates it to improve mixture and reaction speed. The working fluid of the pump cools the biogas by absorbing compressed heat, providing an almost isothermal operating mode that extends the service life of downstream valves, burners, and motors, and reduces maintenance costs. The working fluid of the pump is also used as a fireproof device, which reduces the cost of explosion protection. The contaminated gas is filtered through a water ring and partially dried. In this way, the gas is oxidized and returned to the wastewater treatment program.

 

Vacuum water

As a part of the vacuum water system, the liquid ring pump can be used to reliably collect, transfer and treat wastewater from all areas. Because of its high vacuum properties, the transfer of waste water is easy, even on the upwelling.

 

Biogas production

The number of microorganisms produced by the activated sludge tank and the settling tank is kept stable in the sewage treatment tower to produce biogas. Complete mixing of the sludge can increase gas production and shorten the time in the reactor. In this process, the methane gas is pumped from the top of the waste water treatment tower, compressed inside the compressor, and reintroduced through a nozzle at the bottom.

Wastewater purification/activated sludge tank oxidation

In order to reduce the space requirements and reduce the cost of wastewater treatment equipment, the number of activated sludge tank is increasing. Oxygen is extremely important for wastewater treatment. Our compressors provide the compression pressure needed to produce the maximum oxygen output. For small, dispersed or mobile devices, air - ring fans are the most economical choice.

 

Fish ponds ventilation

Blowing the wind into the pond can greatly improve the quality of life of fish. By using an air-ring fan or a liquid-ring pump, the oxygen content of the water can be greatly increased, which can increase the number of fish in the pond by two times, or even three times. The heat generated by the fan or pump can also be used to regulate the water temperature. The oxygen contained in the water can greatly accelerate the growth and reproduction of fish, and greatly increase the yield.

 

Waste generation gas recovery (biogas)

This use includes gases produced by the decomposition of waste, usually in garbage. Plant waste also breaks down, so the gases produced can be recycled. This is a very basic approach. Simply put, it is to drill holes at various points in the garbage site and put the pipes with holes into the holes. Vacuum pumps are used, or, if the pressure is higher than atmospheric, compressors can be used to compress the gas and transfer it to a natural gas engine, which can be used to drive a generator. The gas can also be used directly to generate electricity or as fuel for boilers or furnaces. This gas can also be cleaned clean, remove the dirty gas, sold to industrial systems, etc.

 

Biogas recovery (biogas)

Civil or industrial wastes are decomposed in mud or storage tanks. The gas is compressed by a compressor into the injection unit and then into the tank, where it is used to provide heat and agitate the mud, keeping it expanding and encouraging microorganisms to eat the decomposition products or mud. Compressors are also used to recover gas and push it into a natural-gas engine to drive a generator to generate electricity, generate electricity, or use it as fuel for a boiler or furnace.

 

Waste disposal

Liquid ring vacuum pumps are installed in trucks to remove industrial waste that cannot be digested through water treatment plants.
