As society advances, people are increasingly high demands on the environment, sewage treatment plants and sewage treatment facilities have been put into use in various cities and industries to effectively solve the problem of sewage sludge treatment and disposal has become an urgent matter.

     The sludge is a resource, some countries started to restrict the sludge directly to landfill, the landfill costs rise, led to the market demand of people of advanced treatment sludge, reduction and resource. The filter press technology has been rapid development of the filter press dewatering equipment as a mature, widely used in the field of environmental protection, and sewage sludge treatment equipment.

Sludge mechanical dewatering of capillary water to remove the sludge particles, ordinary mechanical dewatering of sludge moisture content is often 65% -80%, was the mud pie.

Mechanical dewatering equipment belt filter press, plate and frame filter press and Decanter centrifuge, is commonly used Van filter, separator machine and Kincaid, high pressure filter machine.

Sludge landfill, sludge dewatering can significantly reduce sludge accumulation site, saving the costs incurred in the transport process; for composting of sludge, sludge dewatering to ensure that the compost successfully (the composting process, the general requirements The sludge had a lower moisture content); Should the sludge incineration, sludge dewatering rate can significantly reduce energy consumption for heating.

However, the sludge composition is complex, the smaller the relative density of smaller particles, and often colloidal condition, its not easy to dehydration characteristics, so far. Further enhance the degree of sludge dewatering is a hot research topic at home and abroad.

Low power consumption of belt filter press. Plastic plate and frame filter cake moisture content is low, but adaptable Decanter Decanter centrifuge for sludge flow fluctuations, airtight performance, large capacity, small footprint. Of the past most of the sewage treatment plant using centrifuge, belt filter press and frame filter press, small-scale sewage treatment plants are commonly used dewatering machine. Chamber filter press, membrane filter press is commonly used, as well as the latest sludge dewatering technology Kincaid to the high-pressure metal frame machine, sludge treatment cost is low, the machine production of patented products from Foshan Kincaid filtered Equipment Co., Ltd. R & D The unique technology is ideal for sludge dewatering equipment.

Belt filter press: the continuity of work, and belt press dewatering machine three regions, namely, gravity dewatering zone, wedge dewatering zone and shear dewatering area, the press type is two-dimensional squeeze, mainly used for sewage mud dehydration, but its application is expanding. Belt filter press dewatering results were dependent on chemicals, resulting in high cost of sludge treatment.

Filter Press: Intermittent pressure filtration equipment for a variety of suspensions of solid-liquid separation.

Van filter: developed since the 1960s. Which is characterized by high filtration pressure, maximum pressure reached 4.5MPa; stand-alone filter area, more than 2050 square products abroad advent domestic filter area reached 2000 square cake with the amount of fluid by squeezing filter cake moisture content can be further reduced by 5% to 15%; good corrosion resistance, the filter plates can be a variety of enhanced plastic, light weight, good flexibility, corrosion resistance, wide adaptability; low running costs can be achieved multiple consecutive operations, on-line control. Modern filter press to Van-based.

Diaphragm filter press: Intermittent pressure filtration equipment for a variety of suspensions of solid-liquid separation. The filter press equipped with a rubber squeeze the diaphragm used to filter cake dewatering. Diaphragm expansion of the medium can be compressed air (0.7MPa or less), water (0.7MPa above).

Ultra-high pressure filter presses: the unique structure of filter chamber, the sludge secondary crushing, further reduce the sludge moisture content, the current leading technology.

The the Zhucheng innovative Chinese Environmental Protection Technology Co., Ltd. produces a variety of filter presses, belt filter press product many of the city's sewage treatment plant with praise by the users.
