Energy consumption

Test of energy consumption, conducted by Anlager in February 2007.

The purpose of the test is to measure energy consumption, measured in kilowatts per hour, for a cubic meter of oxygenated water where EFEKTYWNY ™ method to aerate the water has been used. By comparison, data from a municipal water works was used, where the water was aerated with aeration towers and blower.

 

The following information was recorded:

  • The test has been carried out at borehole in Ingelstorp, Ystad municipality.
  • The pump used is an EMS submersible hydroforpump VPI 1500, single-phase with nominal power 1100W.

First test

  • In the first test water was pumped through a water meter and a EFEKTYWNY ™ areator.
  • Energy consumption was scanned on an electricity meter on the power grid from the grid owner EON.
  • The test was carried out over 3 hours, the pressure was 2 kg and flow 4, 2 m ³ of water per hour.
  • Total electricity consumption was 4.5 kwh for 12, 6 m ³ treated water.
  • Energy consumption per cubic water is 0.36 kwh/m ³.

Second test

  • The second test was conducted to determine the power consumption of the well pump where the water was pumped into a water meter and with an open discharge.
  • The test was conducted over 3 hours. The pump consumed 5.0 kwh for 14.5 m ³  of incoming water.
  • Per cubic metre of water equals energy consumption 0.34 kwh/m ³.

Conclusion

EFEKTYWNY ™ energy consumption thus becomes (0.36-0.34) 0.02 kwh/m ³.

A comparison

Aeration Tower and compressor:

  • Aeration tower with a surface area of 2 m ² is filled with water to a depth of 7, 4 m.
  • The compressor is driven by an electric motor with power 12.5 kwh
  • Throughput is 420 m ³/h and power consumption 0.030 kwh/m ³

During the test, the process was stopped at one point whereby the water level in the aeration Tower fell by 0, 35 m, which means that during the process, there were 5% air involved in water.

A study of EFEKTYWNY ™ areator available on the Anlagers website shows that water is aerated with minimum 95% with the EFEKTYWNY ™ process thus 90% more than when the aeration Tower is used.
