When you flush the toilet do you ever think, “Man, all this good stuff is just going to waste?” Ok, probably not. But in the future your home or office may be partially heated by that human waste, thanks to geothermal sewage. What exactly is geothermal sewage, you cringe? It’s the process by which the heat from a wastewater line is repurposed to heat a nearby facility such as a hotel or apartment building. The heat transfer is accomplished by filtering solids from the wastewater and passes through a heat pump before reaching the building. In China geothermal sewage has already been installed in a few buildings, including the Beijing Train Station. Now a wastewater treatment facility in Philadelphia is beginning the first US trial with this technology. It is a company in Philadelphia, NovaThermal Energy, that is making geothermal sewage possible by developing a proprietary filter material that can efficiently remov

We recently updated our Standard method and Application guide to include more filter recommendations for environmental analysis applications. These additions include topics such as the EPA method for extracting oil and grease from water and the Field Leach Test method from the United States Geological Survey. New methods are in addition to our existing collection of procedures which includes topics like air sampling, bacteria counting, and silt density index. The product recommendations that we provide with the methods are based on the requirements set forth by the procedure, as well as input from customers and suppliers.

Sterlitech is now carrying Dow FilmTec flat sheet membranes for reverse osmosis and nanofiltration separations. These high-performance membranes are available in Sepa CF, CF042, or HP4750 sizes, or as 12 x 12 inch sheets. The FilmTec line of spiral wound membranes was created by the experts at Dow Water & Process Solutions for industrial, municipal and commercial water applications. While they have often been used for large industrial processes like power generation and semiconductor plants, with our precut sizes it is easier than ever to implement these membranes for laboratory scale testing with a membrane test cell. For information on how to best utilize each membrane type, consult our application tab for recommended uses on each designation.

Until quite recently, dry baths (sometimes referred to as “incubators” or “block heaters”) were very simple heating machines that would allow users to have marginal control over temperature of samples. With the advent of the digital age and the integration of the microchip into laboratory equipment, this temperature control has become much more accurate and the units have become easier to use. Currently there are a few different models of dry baths out on the market and here is a general summary of some of them: Analog Dry Baths: analog dry baths are the original dry baths available to laboratory personnel.
