How do you calculate the difference between wet ton vs dry ton?

Hi, The difference is calculated by knowing the dry solid content of the sludge. For sludge produced in wastewater treatment plants, we talk about moisture content in terms of percentages or g/L. This is the amount of dry solids per 1L of sludge. When you have 1 ton of sludge at 20% dryness, this equates to 0.2 t of dry matter (1 x 20%). So sludge at 20% dryness is also equivalent to sludge at 200g/L. Hoping this answers your question.
