With simpler operations than a refractometer, the strip verifies that fluids are in good working order to prevent damage to cooling systems. The strips can test for levels in water from 20–60%. Test strips only need to be dipped in water for 2 s to conduct a check. After dipping the strip, users can determine the propylene glycol levels after just 60 s. The strip will change colors, indicating its status. The strip’s color is then matched to an included color chart. — Industrial Test Systems (ITS), Inc., Rock Hill, S.C.
Traditional dissolved-air flotation systems produce the flotation motive water through air saturation of a partial flow in the plant outflow. The saturation usually takes place using multi-stage pumps, which only run smoothly if they are fed with pH-neutral wastewater that is mostly free from solids. The injector system developed by this company achieves micro-bubble formation comparable to saturation by pumps. The air saturation of the partial flow is carried out by an injector pressure container, which is fed by a wastewater pump resistant to solids and which can handle both alkaline and acidic wastewater without any problems. This enables cycles to be driven through flotation systems without chemical conditioning or neutralization. The flocculant dosage is required only to produce separable flocs. If floating solids are present without flocculation, a chemical-free procedure is possible. — EnviroChemie GmbH, Rossdorf, Germany
