Micro-structure helps control diesel emissions
G
EO2 Technologies Incorporated of Woburn, Massachusetts, USA, has developed what it describes as a ground-breaking filtration technology. In light of the health risks associated with automotive emissions, increasingly strict standards and rapidly increasing crude oil prices, the need for clean transportation technology has never been more critical, says the company. In response, it has designed a cross-linked micro-structure for extruded honeycomb filters and catalyst/membrane supports that is making it possible to create more effective and efficient, clean diesel systems. Clean diesel has emerged
as one of the most viable technologies on the market for addressing emissions control challenges, while achieving 20–30% better fuel efficiency than petrol-powered vehicles. The developer of multifunctional filters for next-generation clean diesel engines, has also demonstrated how this micro-structure can be applied to non-automotive applications such as air–oil filtration, absorptive separation and pre-filtration.

Siemens develops biological process optimisation programme
U
S-based Siemens Water Technologies has developed a biological process optimisation programme called ‘BioFlowsheet+ Solutions’. The company says that it integrates the main unit operations of a wastewater treatment plant by evaluating effluent requirements, land availability and specific costfactors such as energy use, labour and disposal costs. According to Siemens, its biological treatment experts can review an entire system and ensure process integration and optimisation
– with a single point of process responsibility. ‘Siemens is in a unique position to combine years of process knowledge, along with the broadest array of biological technologies, providing real value to our customers,’ said Chuck Gordon, Executive Vice President of Siemens Water Technologies.

Membrane performance improved
S
tart-up company Stonybrook Purification claims that it is developing a technology that can dramatically lower the cost of making clean water. The US-based company is planning to bring to market technology that increases the performance of high flux membranes for a variety of purification, filtration and desalination applications. It also has the potential to reduce the costs of processing water on a large scale. The ‘spin-out’ of Stony Brook University recently announced the close of the first
tranche of a US$4.1-million Series A investment led by Battery Ventures. T2 Venture Capital, the founding investor and early incubator of the company, also participated in this round, along with new investors Modern Water and TianDi Growth Capital.
