Water Treatment Solutions for Power Plants 

Power plants around the world are continuously looking for ways to improve their efficiency whilst lowering customer costs. One way to do this is by installing reliable membrane technologies like microfiltration. During the VGB Conference “Chemistry in Power Plants 2012” (October 24th-25th) in Hamburg, Germany, a few members from Pall Corporation will showcase examples as to how these technologies can work, reduce costs and improve processes.

This is an international conference aimed for operators of energy utilities and industrial power plants. Mr. Doll and Dr. Venkatadri from Pall Corporation will make their presentations on October 25th.

“Today’s power plants are under significant pressure to meet both environmental and economic demands,” said Mr. Doll. “Pall’s technology gives them the opportunity to not only meet increasingly stringent regulations, but to save money in the process.”

There are a number of different factors that can contribute to the success for power plants. These can include regulatory limitations on heavy metals, community acceptance, efficient machinery and processes, and resource availability. In particular, significant volumes of water are required for cooling, boiler feed water, and scrubber make-up.

The Pall Aria system is one of Pall's leading water treatment solutions and utilises unique hollow fibre membranes. With these hollow fibre membranes the Aria system offers outstanding regeneration capabilities. The fibres also help to ensure consistent system performance and reliability.

“With hundreds of Pall AriaTM membrane water treatment system installations worldwide, Pall has gained tremendous expertise in water treatment in power plants as well as many other industrial and municipal sites,” adds Mr. Doll. “Power plants will benefit from technology designed to meet their specific water treatment needs.”

Mr. Doll and Dr. Venkatadri will present three separate case studies highlighting laundry waste water treatment, improvements in boiler feed water quality, and improved economics in cooling tower blowdown water treatment.

Bernhard Doll is an expert in the field of membrane separation systems for water and wastewater treatment, with more than 19 years of filtration, separation, and purification experience serving customers in industrial and municipal markets. Mr. Doll earned his diploma in Mechanical Engineering during his studies at the University of Applied Sciences and Arts in Dortmund, Germany.

Ram Venkatadri is global marketing manager in the Energy group of Pall. He holds a Bachelor of Technology in chemical engineering from the University of Madras and a Ph.D. in chemical engineering from the University of Pittsburgh. Dr. Venkatadri has more than 20 years of experience in the power, polymer, olefin, and refining industries.
