The Dazhang high pressure program controlled membrane filter press stands at the forefront of innovation by integrating advanced TPE diaphragm technology. This cutting-edge design offers an impressive longevity, exceptional membrane flexibility, and robust resistance to both acids and alkalis, making it the ideal solution for a diverse range of industries. Whether you choose air or water pressure for compression, the system's capabilities are astounding, with water pressure soaring to an impressive 0.8-4.0 MPa.
Our state-of-the-art variable filter chamber technology revolutionizes solid-liquid separation across a spectrum of industries, including petrochemical, mining & metallurgy, food & medicine, coal washing, papermaking, pigment dyes, new energy lithium batteries, photovoltaics, and fly ash desalination. This innovative approach not only enhances production efficiency but also significantly reduces the moisture content of the filter cake. The system offers flexibility with pressure levels ranging from standard diaphragm pressing of 0.8-1.6Mpa to ultra-high pressure diaphragm pressing, accommodating different operational needs with equipment options reaching 2.0-4.0Mpa.
Our pioneering high-pressure dewatering technology is a game-changer in the municipal domestic sludge dewatering sector. It efficiently minimizes the filter cake's moisture content, adhering to the strictest standards for landfill and incineration, with municipal sludge achieving an exceptional moisture content range of 35%-60%. This advanced technology outperforms traditional dewatering equipment, facilitating effective sludge reduction treatment.
Experience unparalleled efficiency with our dehydration system, designed for seamless automated operation. It offers an array of options, including a filter cake auxiliary discharge system, an online filter cloth flushing system, and an automatic valve instrument, all working in harmony to ensure fully unmanned operation, maximizing productivity and minimizing human intervention.
