The Dazhang high pressure program controlled membrane filter press incorporates cutting-edge TPE diaphragm technology known for its exceptional durability and flexibility. With a robust resistance to both acidic and alkaline substances, this innovative solution is ideal for a myriad of industries. Offering the versatility of either air or water pressure for pressing, it achieves an impressive water pressure range of 0.8-4.0 MPa, ensuring consistent and reliable performance.
Our advanced variable filter chamber technology is revolutionizing solid-liquid separation across diverse industries including petrochemical, mining, metallurgy, food, pharmaceuticals, coal washing, paper production, pigment dyes, new energy lithium batteries, photovoltaics, and fly ash desalination. By significantly enhancing production efficiency and minimizing filter cake moisture content, this technology meets a spectrum of needs. Choose between conventional diaphragm pressing at pressures of 0.8-1.6Mpa or opt for ultra-high pressure diaphragm pressing equipment ranging from 2.0-4.0Mpa, tailored to suit various operational demands.
In the municipal domestic sludge dewatering sector, our high-pressure dewatering technology stands out by reducing filter cake moisture content to optimal levels suitable for landfill and incineration, achieving a remarkable 35%-60% moisture content in municipal sludge. This is a significant improvement over traditional dewatering methods, leading to more efficient sludge reduction treatment.
Experience the next level of efficiency with our dehydration system, designed for full automation. It can be seamlessly integrated with auxiliary systems for filter cake discharge, online filter cloth flushing, and automatic valve instrumentation, enabling truly unmanned operation.
