Hydro MicroScreen Pulp & Paper Wastewater Solution

Hydro MicroScreen™ helps a California pulp and paper plant replace an unreliable plate and frame press - improving performance and paying for itself in just six months.

Case Study: Hydro MicroScreen™ Pulp and Paper Solutions

A California pulp and paper plant were using a plate and frame press to remove Total Suspended Solids (TSS) from their process wastewater stream. The press was a maintenance nightmare, it would frequently break down forcing them to shut the entire plant down until they could repair it. Cleaning and reassembling the press took three people one full shift every week. They were wasting 1,200 man-hours each year just keeping their frame and press system operational – not to mention the impacts of the associated downtime.

Looking for a better solution, plant staff contacted Hydro International to have a demonstration run of the Hydro MicroScreen™ rotating belt screen system at their plant, on their flows. After a single shift of operation, the Hydro MicroScreen™ never required cleaning or maintenance and was shown to capture twice as much solids as the plate and frame press in the same amount of time. Solids output from the Hydro MicroScreen™ system were dry enough that they could be sent directly to landfill without any additional processing.

Pleased with the performance, and eager to get rid of their plate and frame press problems, the plant ordered a Hydro MicroScreen™ system. It is expected that the Hydro MicroScreen™ system will get a 100% ROI from the system in just over 6 months from plate and frame maintenance reductions alone!
