Shanghai Dazhang Environment Protection Equipment Co., Ltd. proudly presents the Advanced Membrane Filter Press 1250 with 870 mm Square Plates, a pinnacle of engineering excellence. This high-pressure, program-controlled marvel incorporates cutting-edge TPE diaphragm technology, leading the international market. Its robust design promises an extended service life, exceptional membrane shrinkage, and unparalleled resistance to strong acids and alkalis. Perfectly engineered for diverse industries, it adeptly utilizes either air or water pressure, achieving impressive water pressures ranging from 0.8 to a remarkable 4.0 MPa.
Revolutionizing the realm of solid-liquid separation, our variable filter chamber technology is an indispensable asset across an array of industries. Whether in petrochemical, mining, metallurgy, food, medicine, coal washing, paper making, pigment dyes, or the burgeoning sectors of new energy lithium batteries, and photovoltaics, this technology significantly boosts production efficiency and minimizes filter cake moisture content. Our filter press caters to various pressure requirements with conventional diaphragm pressing from 0.8-1.6Mpa and an ultra-high pressure diaphragm for those demanding settings, offering equipment capable of pressures between 2.0-4.0Mpa.
In the municipal domestic sludge dewatering industry, our high-pressure dewatering technology shines; it effectively reduces the filter cake's moisture content, adhering to the strictest landfill and incineration standards, achieving an impressive range of 35%-60% moisture content. Compared to conventional dewatering systems, this technology provides a superior sludge reduction treatment, setting a new standard in environmental management and operational efficiency.
Our state-of-the-art dehydration system transforms operational efficiency with its fully automated capabilities. With the ability to integrate auxiliary discharge systems for filter cakes, an innovative filter cloth online flushing system, and automatic valve instruments, the system is designed for seamless, unmanned operation. This automation ensures a streamlined, hands-off approach that optimizes productivity and reliability.
