P & ID for A/D Power Plant

Suspension Feed: Fixed Feed


• The feed of the suspension is

• continuous by the feed device

• The suspension is evenly

• spread on the filter cloth by a

• weight loaded weir plate

• Solids loading = 55%

Cake Discharge

• Cake discharge from a

• 12 m2 belt filter producing 10

• tons/hour of dry gypsum solids

• Cake Depth = 50 mm

• Moisture < 10 %

• Chlorides < 100 ppm from an

• initial level of 20,000 ppm



Filter Cloth Wash

• Typical cloth wash box design

• Filter cloth wash liquid recycle

• line is included
