Cutting the waste in wastewater treatment


The Robuschi Robox Screw 1(1)Gardner Denver has launched its new Robuschi Robox Screw compressor and blower package for the wastewater treatment industry; designed to save customers up to 30 per cent on their energy consumption.

The new Robuschi Robox Screw package is available in high (up to 2.5 bar) and low pressure (1 bar) configurations. In this sponsored post, the firm says the screw packages a range of innovative features to provide a robust yet simple construction that delivers high performance in aggressive environments such as water purification, effluent treatment and biogas applications.

At the core of the new package is the RSW compressor, which has been purposed-designed for longevity and performance. Gardner Denver says its robust construction incorporates oxidation-resistant coating on the rotor shafts, to ensure performance levels are maintained and, the wide-diameter shafts help to reduce the deformation caused by internal and external loads, meaning the compressor can work efficiently in even the harshest conditions.

The unit’s oil-free design provides clean air to the process, to avoid the risk of oil contamination in the water supply or adversely affecting the biodegrading process. It provides the maximum airflow, up to 10,500 m3/h to deliver a consistent supply of air to the application.

Robuschi engineers designed the package with a simple construction with the minimum number of component parts to help reduce maintenance and service costs and make installation quick and straightforward. The compressor features a traditional belt drive in place of a gear overdrive and for applications with a reduced thermal speed, uses a simplified lubrication system. Together with the low rotor rotation speed, Gardner Denver says these features deliver very quiet running and keep sound emissions to a minimum.

Gardner Denver launched the screw at Utility Week Live last week, where experts from the company’s Elmo Rietschle product range were also demonstrating the new GBH-8 side channel blower together with representatives from the Wittig range of compressors for air and process gas applications.

Purpose-designed for aggressive water industry environments, Wittig rotary vane compressors can be used to boost pressure in biogas applications and for sludge agitation during the digestion process.
