There are primarily two types of sand filters used in the wastewater treatment process: rapid (gravity) sand filters and slow sand filters. Rapid (Gravity) Sand Filters: Use larger sand grains and operate at high flow rates. Typically include a system to wash the sand, which allows these filters to handle heavier loads. Efficient for treating ...

Sludge Dewatering and Thickening

Sand drying beds have a bottom layer covered in graded gravel that ranges from 8 - 18 inches in depth. The gravel sits on top of an undrain system which is made from perforated pipe. The gravel layer is topped with approximately 12 inches of sand. Sand drying beds accomplish dewatering through water drainage and evaporation.
