Komax Systems has released a non-clogging high efficiency sludge heat exchanger based on its proven Hi-Pass™ non-clogging static mixer designed specifically for sludge and heavy slurry applications. Klean-Flow heat exchangers are designed with contoured elements to maximize heat transfer while eliminating corners that can trap solid or fibrous materials. This highly turbulent flow creates a scavenging environment, continually cleaning the walls of the pipe for maximum heat transfer. The Klean-Wall design will readily pass individual solid items with a nominal diameter up to half that of the tube diameters. Komax Systems Inc., Wilmington, CA, 800-826-0760,

The EPA set limit guidelines for "oily wastes" discharges from facilities using any type of oil and grease in manufacturing, and fined several U.S. biodiesel plants recently for illegal discharges of vegetable-based oil and grease pollution in nearby streams. With the portable, easy-to-use InfraCal™ TOG/TPH Analyzer, Model HATR-T2 or the Model CVH – depending on solvent selected for the extraction process – onsite determinations of the total oil and grease concentration in discharges can be easily and accurately determined in 10-15 minutes.
