Belt filter press, chamber filter press, centrifuge, dry naturally, such as sludge dewatering equipment and methods, advantages, disadvantages comparison:

     : Belt filter press (continuous dehydration, mechanical squeeze), especially suitable for the dehydration of inorganic sludge, organic sludge NA.

    Advantages: 1) machine manufacturing is easy, ancillary equipment, low energy consumption; 2) continuous operation, management, dehydration.

    Disadvantages: 1) polymer prices expensive, high operating costs; 2) dehydration efficiency is less than the frame plate filter press.

    The two Van filter generally has the following characteristics:

    Mechanical dewatering, for intermittent operation, the filter capacity is low; infrastructure investment in equipment. Other dewatering equipment NA occasions; need to reduce transportation, drying or incineration costs; reduce landfill costs occasions.

    Advantages: 1) intermittent dehydration; 2) hydraulic filter.

    Disadvantages: 1) cake solids rate; 2) solid recovery; 3) consumption of drugs.

    : Natural drying for the percolation of good sludge dewatering, the climate is relatively dry areas, wet areas should not be built in open land areas of tension, environmental health permitted areas.
