Sludge, a by-product of the wastewater treatment process, must be economically processed for disposal or beneficial reuse. This is a multi-step process. Both primary and secondary sludges are mostly water (often in the 0.5 – 2% solids range) and the first step in the further treatment of sludge is removal of water. 

Rotary drum thickeners have become the popular choice because they have a small footprint and consume low amounts of water, power and expensive polymer. Plus, they offer flexible features to adjust to changing sludge conditions over the next 20 years.  

Typical performance of the Parkson ThickTech Rotary Drum Thickener is to remove over 90% of water from incoming sludges, thereby greatly reducing the sludge volume and size of the next treatment step.
