A new sample preparation system for on-line monitors is being introduced by Bran+ Luebbe. The CeraClean Filtration Unit removes solids, colloids, and high molecular weight compounds from water and wastewater, and provides a continuous supply of clean filtrate for on-line monitors. The CeraClean works with grease removal, sludge treatment, commercial washing utilities, and soil leachate monitoring stations. Designed to minimize maintenance time, the CeraClean features an automatic back-flush system that more than doubles the interval between cleaning. Energy costs are reduced by 50%.
