Webinars

Building blocks: how can renewable energy reach its potential?
Announcing the latest Renewable Energy Focus interactive webinar, in association with the World Future Energy Summit - Abu Dhabi, 2011.
MBR Retrofit: Design Principles and Best Practice
Membrane bioreactors (MBR) with submerged membrane modules have set the standard for the next generation of biological wastewater treatment plants as they offer two main advantages; a significantly improved effluent quality and a substantially smaller footprint. Besides the huge application for municipal wastewater treatment, there is a growing and diverse industrial applications segment where MBR technology is being implemented.
What does the future hold for renewable energy in the Middle East?
We are pleased to announce a new webinar from Renewable Energy Focus in association with the World Future Energy Summit, which addresses the future for renewable energy in the Middle East.

MBRs Don’t Have to Break the Bank
Membrane Bioreactors (MBRs) may have a reputation for being costly, but they don’t have to be. A survey of 137 MBRs on the US mainland shows that an MBR using flat plate technology is typically half to three-quarters the capital expenditure (CAPEX) of hollow fiber systems. There is some data that suggests MBR Systems are competitive with several other technologies, including oxidation ditches, SBRs, MBBRs, and BNR plants. There is insufficient data to say definitively that a flat plate system costs less, but the data suggests that it can be cost effective versus conventional systems treating to the same quality effluent.
Low Energy MBR Solutions
The City of Santa Paula, Calif. is home to the first large membrane bioreactor (MBR) installation in North America to use PURON™ membrane filtration modules. It is also the first water recycling facility built under a California government code to encourage private investment to solve public infrastructure needs Santa Paula’s outdated wastewater facility was in violation of several discharge requirements issued by the Los Angeles Regional Water Quality Control Board, and had received more than 3,000 violations and $8 million in fines.
Food and beverage: Linking filter performance and product safety
Controlling levels of contamination in the food and beverage industries is a key role of filtration. Dr Ralph Heusslein and Ursula Brendel-Thimmel of Pall Corporation, Scientific and Laboratory Services, explain the links between filter performance and microbiological product safety.
Seawater desalination: Current trends and challenges
Changing climate patterns, population growth pressures and the limited availability of new and inexpensive fresh water supplies are shifting the water industry's attention. In an emerging trend, the world is reaching to the ocean for fresh water. Nikolay Voutchkov from Water Globe Consulting explains recent trends and explains his predictions for the future market.
New centrifuge pond level control system handles variable feeds
Recent studies have shown that the control of pond depth can be used to improve the performance of centrifuges used in a wastewater treatment plant.
