The Dazhang high-pressure, program-controlled membrane filter press proudly utilizes cutting-edge TPE diaphragm technology, celebrated for its extraordinary durability and innovation. This advanced system not only ensures an extended service life but also boasts remarkable membrane flexibility, making it a powerhouse in the industry. It demonstrates exceptional resistance to both strong acids and alkalis, rendering it perfect for a multitude of industries. The highly adaptable pressing mechanism accommodates the use of either air or water pressure, with water pressure impressively reaching 0.8-4.0 MPa.
Embrace the revolution of variable filter chamber technology, a pivotal advancement in solid-liquid separation across diverse sectors such as petrochemical, mining, metallurgy, food and medicine, coal washing, paper making, pigment dyes, new energy lithium batteries, photovoltaics, and fly ash desalination. This cutting-edge technology dramatically enhances production efficiency while minimizing the moisture content of filter cakes. Our systems provide an extensive range of pressure options, from conventional diaphragm pressing at 0.8-1.6 Mpa to ultra-high pressure diaphragm pressing, accommodating different operational needs with precision across pressure levels of 2.0-4.0 Mpa.
By leveraging high-pressure dewatering technology in municipal domestic sludge dewatering processes, our solution effectively reduces the filter cake's moisture content to industry-leading levels. It meets landfill and incineration standards with a moisture content range of 35%-60% for municipal sludge, representing a groundbreaking advancement in sludge reduction. This surpasses traditional dewatering equipment, setting new benchmarks in efficiency and performance.
Step into the future of efficiency with our dehydration system, meticulously designed for seamless automated operation. Boost productivity further with optional features such as a filter cake auxiliary discharge system, an online filter cloth flushing system, and state-of-the-art automatic valve instrumentation, all engineered to achieve a truly unmanned operation. Elevate your operations to new heights with unprecedented efficiency.
