These units are used in both municipal and industrial sectors, as well as in applications requiring the highest possible degree of dewatering (such as drying facilities or situations involving high sludge disposal costs). Bucher piston presses feature Swiss technology renowned for exceptional technical longevity; the oldest units in Poland date back to 1970 and remain in continuous operation to this day. Bucher piston presses are among the most efficient systems for sewage sludge dewatering. Thanks to their robust construction, precision engineering, and reliable technology, they achieve the highest dry matter content—up to 45%—while maintaining stable filtrate quality that is unsurpassed on the market.
