This drum vacuum is equipped with double-filter protection

This 110-gallon heavy-duty industrial vacuum (photo) is designed to move material with little wear to the equipment. Engineered to filter contaminants to high-efficiency particulate air (HEPA) requirements, the vacuum is fitted with two filters: a pre-filter to stop larger particles…

Modular piping system now has adapter flanges, too

This company has simplified transitions to its modular pipework system by introducing adapter flanges, which are available in square or round form. The new adapters are welded onto the machine outlet or inlet ports. Matching counter flanges from the company’s…

Using algae to make beta-1,3- glucan

With a separate algae-based technology, Algal Scientific has invented a sterile fermentation process for making beta-1,3-glucan from algae that has lower costs than those associated with fermenting the molecule with yeast. Beta-1,3-glucan is a polysaccharide that boosts immune-system function in…

Using algae to clean wastewater

Technology developed by Algal Scientific Corp. (Northville, Mich.; www.algalscientific.com) uses algae to remove soluble organics, nitrogen and phosphorous from medium- to high-strength wastewaters in a single step. The technology is an alternative to multistep treatment processes involving the use of…

This PEM fuel cell has H2 storage built-in

Conventional hydrogen-based systems designed to store electrical energy (from solar arrays, for example) typically feed electricity to a proton-exchange-membrane (PEM) electrolyzer to generate H2 from water. This H2 is then compressed and stored in a cylinder, or as a metal…

This demonstration plant makes bioethanol from tapioca residue

In April, a demonstration plant started up that makes bioethanol from cassava residue — a byproduct of tapioca production. The demonstration plant, located at the cassava starch plant of EBP Ethanol Co. in Sa Kaeo Province, Thailand, is part of…

Grappling with Graphene: The race to commercialization

In the ten years since its first isolation by a pair of physicists, the single-atom-thick carbon allotrope known as graphene has been extolled as a “miracle material” for everything from television screens to tennis rackets to superabsorbent fabrics. What excites…
