The ThickTech Rotary Drum Thickener from Parkson Corporation is ideal for biosolids thickening and can be used to increase capacity of other solids-handling equipment, such as dewatering. Fabricated of stainless steel, it is engineered to provide years of reliable service. The updated drum design allows for higher efficiency and reduced floc shear. Internals include roll bars and split augers to ensure complete sludge turnover in three dimensions and flights to regulate flow. It uses woven wire mesh screens, which have small individual opening sizes, yet possess high overall open area. As a result, sludge volume reduction of 90 percent and a 98 percent capture rate are achievable, all with very low polymer usage. 888/727-5766;
