Shanghai Dazhang Environment Protection Equipment Co., Ltd. proudly presents the Membrane Filter Press 1250, engineered with cutting-edge TPE diaphragm technology. This advanced high-pressure, program-controlled membrane filter press is globally recognized for its remarkable longevity, exceptional membrane flexibility, and robust resistance to acids and alkalis. Designed for versatility, it effectively caters to a broad spectrum of industries. Utilizing either air or water pressure for pressing, this robust device supports water pressures ranging from 0.8 to 4.0 MPa, ensuring reliable operation in diverse settings.
Our innovative variable filter chamber technology sets a new standard in solid-liquid separation across numerous industries, including petrochemical, mining, metallurgy, food, pharmaceuticals, coal washing, paper manufacturing, pigment dyes, new energy sectors like lithium batteries, photovoltaics, and even fly ash desalination. This technology significantly enhances production efficiency while minimizing the moisture content of filter cakes. Choose from conventional diaphragm pressing with pressures of 0.8-1.6 Mpa, or opt for ultra-high pressure diaphragm pressing with options ranging from 2.0-4.0 Mpa, tailored to meet the demands of varying operational conditions.
The integration of high-pressure dewatering technology in municipal domestic sludge treatment represents a significant advancement, effectively reducing filter cake moisture levels to compliant standards for landfill and incineration purposes. Impressively, this technology reduces municipal sludge to a moisture content as low as 35%-60%, marking a substantial improvement over traditional dewatering methods and facilitating efficient sludge reduction treatment.
Our state-of-the-art dehydration system is designed for fully automated operation, enhancing efficiency and reducing the need for manual intervention. Equipped with a comprehensive suite of features including a filter cake auxiliary discharge system, an online filter cloth flushing system, and automatic valve instrumentation, this system epitomizes the future of unmanned operation, streamlining processes and maximizing productivity with unparalleled precision.
