Next Generation Belt Press Increases Capacity and Performance

The wastewater treatment plant in Plattsburgh, New York, had four belt presses that were originally installed in the 1980s. As those machines started to show their age, the city began looking at replacement options, initially considering screw press and centrifuge technology.

The City of Plattsburgh worked with CDM Smith to evaluate dewatering options and design the upgrade. They decided to go with two 3DP Belt Presses from BDP Industries. One machine is able to process the full loading requirements and the discharge cake solids have increased from 23% to 27%.

This result is not all that unique, according to the manufacturer. “The 3DP Belt Press from BDP Industries has pushed the boundaries of belt press technology for over two decades,” says a company spokesperson. “From the beginning, the 3DP set a new bar for increased performance and reduced O&M, and the latest generation jumps even further ahead of traditional belt presses.”

Features include an independent gravity zone, feedbox paddlewheel, curved wedge zone, vertical pressure section, rack-and-pinion hydraulic tensioning, and 70 PLI construction with heavy-duty rollers and bearings. Today’s 3DP is now also offered with odor and filtrate containment, along with full system automation.

BDP Industries is a leading supplier of dewatering, thickening and composting equipment with thousands of installations worldwide. Products include belt presses, screw presses, gravity belt and rotary drum thickeners, and in-vessel composting systems. All products are custom designed and manufactured in the United States.
