De-watering Box Cake Removal
One problem that can occur when using a de-watering box with a dense sludge is that after drying, the dried material or cake, can stick inside the de-watering box.
Filter Cloth is a Simple Solution
A simple solution to this is to line the de-watering box with a filter cloth. When you dump the hopper, just throw the filter cloth away along with the cake and start over. An inexpensive Poly Ethylene or Rayon filter cloth works well for this situation. Filter cloth can be purchased in rolls up to six feet in width. A typical filter cloth application for a small, one to three yard dewatering hopper, is to purchase a 250 yard roll of 36 inch width filter paper. Typical cost is around $250 per roll.
