Shanghai Dazhang Environment Protection Equipment Co., Ltd. proudly presents the High-Efficiency Membrane Filter Press 1250, designed specifically for 35 mm cake thickness. This state-of-the-art filter press incorporates world-leading TPE diaphragm technology, renowned for its exceptional durability and outstanding membrane shrinkage. It boasts remarkable resistance to both strong acids and alkalis, making it a versatile choice for a wide array of industries. Whether employing air pressure or water pressure, the system is adept at pressing, with water pressure capabilities ranging from 0.8 to an impressive 4.0 MPa.
Embrace the future of solid-liquid separation with our advanced variable filter chamber technology, extensively applied across diverse industries including petrochemical, mining, metallurgy, food processing, pharmaceuticals, coal washing, papermaking, pigment dyes, lithium battery production, solar energy, fly ash desalination, and more. This innovation drastically boosts production efficiency while significantly lowering filter cake moisture content. Choose from our conventional diaphragm pressing options, ranging from 0.8 to 1.6 MPa, or opt for our ultra-high pressure diaphragm pressing equipment, offering 2.0 to 4.0 MPa, to perfectly align with your specific operational requirements.
In the realm of municipal domestic sludge dewatering, our high-pressure dewatering technology sets new benchmarks by reducing filter cake moisture content to levels suitable for landfill and incineration standards. This means achieving a moisture range of 35%-60% in municipal sludge, effectively outperforming traditional dewatering methods and delivering superior sludge reduction treatment.
Our sophisticated dehydration system is engineered for seamless automated operation, integrated with features such as a filter cake auxiliary discharge system, an online filter cloth flushing system, and automatic valve instrumentation. This cutting-edge design ensures efficient, unmanned operation, optimizing productivity with minimal supervision.
