The plate-and-frame filter press is the oldest design but still the right choice for thick cakes, cake-washing duty, and pharmaceutical clarification. Here is when to specify it over a chamber press.
Filter press tailings dewatering reduces mine waste volume by 70%, eliminates tailings dam risk, and enables water recycle of 90%+. Here is how the technology and economics work.
Selecting the wrong filter press costs 2-5x in lifetime operating expense. This guide walks through the four key decisions: chamber vs plate-and-frame vs membrane, plate size, automation level, and material.
Reverse osmosis (RO) systems produce 99%+ pure water for filter cloth washing, laboratory dilution, and process makeup. System design, membrane selection, and water recovery explained.
Multi-disc screw presses dewater municipal and industrial sludge continuously to 18-25% dry solids, using 90% less energy than a centrifuge. Operating principle, capacity selection, and limits explained.
Ceramic plunger pumps deliver the 1.6-3.0 MPa pressure required by membrane filter presses, with abrasion resistance that beats steel by 10x. When and how to specify them.
