An improved PHA-bioplastic process is scaled up

A less expensive process for producing biodegradeable polyhydroxyalkanoate (PHA) plastics from renewable feedstocks is being scaled up by a factor of six, resulting in a 30,000–60,000-lb/mo pilot facility. The improved PHA process — developed by Meredian Inc. (Bainbridge, Ga.; www.meredianpha.com)…

Producing Ethanol from Lignocellulosic Biomass

Pressing global issues, such as climate change and declining energy security, have led to an increasing interest in the use of renewable feedstocks for fuel production. These feedstocks include lignocellulosic materials, such as waste biomass from the agriculture and forest…

A Primer on Reverse Osmosis Technology

Water scarcity is one of the most serious global challenges of our time. Desalination and water reuse are effective and reliable means to provide new water resources. Among the many methods available to treat water, reverse osmosis (RO) has widely…

This recirculation pump doesn’t need external cooling

Early this month, this company launched a new generation of hot-water recirculation pumps for large industrial heating systems as well as forced-circulation boilers and district heating systems. The horizontal, radially split single-stage volute casing pumps feature a back pull-out design.…

A new slurry pump that handles high volumes

The new Wirth triplex double-acting piston diaphragm (TDPM) pump combines two well established and proven pumping principles for the transport of high volumes of abrasive slurry. The Wirth TDPM works on the triplex double-acting principle. It has flowrates of up…

A membrane module for large-scale MBR applications

In May, this company officially launched its Bio-Cel XL submerged module for membrane bioreactors (MBRs) at IFAT 2014 in Munich, and already received its first order during the show. This new XL-version of the Bio-Cel has a total membrane area…

Achieve clear filtrate with these candle filters

The further developed CF Series candle filters are particularly suitable for purifying industrial wastewater with low solids content. They have been specially developed for the filtration of liquids with solid concentration of less than 1% — an area of limited…

This blower is now even more energy efficient

The E-Blower extends the high-efficiency solution provided by the company’s Delta Hybrid series in the low volume flow range. The new E-Design delivers a reduction of power demand of up to 4%, depending on volume flow and pressure difference, says…
