Advanced hollow fiber UF membranes improve performance in tertiary water treatment
Growing global demand for clean water and increasing environmental concerns make membrane filtration the technology of choice for municipalities and industries seeking to reuse wastewater and reduce their water footprint. But how is the technology developing in this field?
Advanced Conversion: Maximising the Potential for Energy from Waste
One of the most readily-available and viable solutions to help address the challenge of our growing energy needs is Energy-from-Waste (EfW) – which has the potential to take a multitude of waste streams (such as municipal solid waste) and convert them into energy. We look at how modern techniques can make the technology more efficient.
