Sandoz Pvt Ltd saves up to 17% energy using Atlas Copco low pressure screw blowers at ETP Plant.


Pune, India, January 9, 2014: Sandoz Pvt Ltd. has achieved an average of 17% energy efficiency and lower noise levels by choosing Atlas Copco screw blower technology for its effluent treatment plant at their factory in Navi Mumbai, India.

Sandoz has established targets on reducing the carbon footprint by using the resources efficiently. It has planned a reduction of 1.5% of total site consumption every year.  Selecting an Atlas Copco screw blower was a right step toward achieving the energy efficiency goal.

The aeration process in Sandoz effluent treatment plant was being managed by the conventional lobe blowers.  After experiencing reliability problems with the lobe blowers, it was decided to shift to the new technology of screw blowers. An Atlas Copco ZS screw technology blower with variable speed drive presented an opportunity not only to guarantee reliable performance but also save on energy use.

“Atlas Copco low pressure screw blower was the right replacement for the conventional lobe blower, which consumed more energy and had very high noise levels. Atlas Copco installed a ZS 18 Variable Speed Drive Blower in July 2013, and the customer could notice the results within a few months”, says R Narayanan, Business Line Manager, Oil Free Air, Atlas Copco Compressor Technique.

Like Sandoz, there are many industries that use air blowers for their processes, especially those that operate wastewater treatment plants where aeration air blowers typically represent up to 70 percent of total electricity costs. In the treatment process, millions of bacteria feed on organic waste, breaking it up into carbon dioxide, nitrogen gas and water and, because the bacteria need oxygen, a large quantity of air is needed to be blown into the aeration tanks. There are the typical applications that can benefit from the energy efficiency of rotary screw air blowers.

Atlas Copco’s latest ZS+ range of oil-free, energy-saving positive displacement screw blowers is designed to meet today’s low carbon economy needs. With ZS screw blower technology on average 30 percent more energy efficient, when compared to conventional lobe-type, low-pressure air solutions.

“Our structured approach to minimize our environmental impact has helped us make considerable progress. Our waste management strategy is to prevent, reduce and recycle waste before treatment, incineration or disposal. Effluent Treatment Plant is very critical for us to ensure that we walk our talk. Atlas Copco’s low pressure screw blowers have helped us take an important step towards reducing energy cost and keeping the plant operating efficiently", says Nitin Chaudhari, Assistant Manager, Engineering, Sandoz Pvt. Ltd.
