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.

Seawater desalination faces a number of challenges in the USA. Nikolay Voutchkov of Water Globe Consulting, LLC, explains some of these and looks at ways they can be tackled.
Nuclear power generation: Improving HEPA filter trains through effective pre-filtration
Cost and waste volume reduction is an important goal in the nuclear power generation industry. Chris Chadwick of the Porvair Filtration Group discusses ways in which the efficiency of HEPA filter trains could be improved through effective pre-filtration.
The rise of membrane bioreactors The rise of membrane bioreactors
The membrane bioreactor has become an important processing tool in the treatment of waste liquids and of suspensions of waste solids. Ken Sutherland reviews its history, looks at its current applications, and comments on likely trends.
Air filtration: Cutting emissions in air handling
A European airport chose to reduce energy consumption and CO2 emissions at its air handling plant. This required the installation of energy efficient technology and processes. Following a full review of the airport's air handling system, pocket filters were chosen which have cut maintenance time, emissions and costs.

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.
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.
Air filtration: Shedding of particles from HVAC filters
A team put together by CETIAT, the study, testing and calibration laboratory in France, has been investingating the problem of particle shedding from HVAC filters. The project is searching for a reproducible method of testing filters in different laboratories. Alain Ginestet and Dominique Pugnet of CETIAT and Magnus Johnsson and Thomas Carlsson of Vokes Air outline what has been discovered to date.
Bioremediation: Wastewater treatment in diesal power stations
Dealing with the contaminants in the wastewater output of a diesel power plant can be problematical. This article provides an outline of the new developments in a method of bioremediation which can improve the efficiency of the wastewater treatment.
