Utile Engineering vane compressors for sludge mixing

Click2Contact

When it comes to sludge mixing in anaerobic digesters, the method used should be energy efficient, provide high biogas yield and be easy to install or retrofit. Hurll Nu-Way offers a gas-mixing diffuser method using vane compressors, manufactured by British company Utile Engineering.

In this method, the gas produced by the heated sludge is compressed by the sliding-vane compressor skid and feeds the biogas at high pressure to the gas diffusing system, placed on the bottom of the digester. The gas creates a large-scale mixing pattern in the digester, providing homogenous mixing to the sludge.

No dead spots are found within the tank and there is no sedimentation build-up or pipe blockage. The method offers reliable and efficient sludge mixing, warranting high yields of biogas and pacification of volatile organic compounds.

The sliding vane gas compressor uses a simple, proven design to compress the gas inside the heavy-duty ductile iron cylinder, resulting in a quiet machine that delivers pulsation-free gas. Vane compressors are easy to maintain, absorb roughly a third of the power required for pump mixing and have considerably low whole life cycle costs.
