Verti-Press Exercise:

Task: A municipality is considering investing in a Verti-Press system to improve its sewage sludge dewatering process. They currently handle 100 tons of sludge per day, with a moisture content of 80%. They estimate that the Verti-Press can reduce the moisture content to 50%.

Calculate:

  1. The volume of sludge before and after dewatering using the Verti-Press.
  2. The reduction in sludge volume achieved by the Verti-Press.

Assumptions: * Density of sludge is 1 ton/m³. * Volume = Mass / Density

Exercice Correction

1. **Volume before dewatering:** * Mass = 100 tons * Density = 1 ton/m³ * Volume = 100 tons / 1 ton/m³ = 100 m³ 2. **Volume after dewatering:** * Mass = 100 tons * Moisture content = 50% * Solid content = 50% (100 tons - 50 tons = 50 tons of solids) * Density of solids = 1 ton/m³ * Volume of solids = 50 tons / 1 ton/m³ = 50 m³ 3. **Reduction in sludge volume:** * Reduction = (Initial Volume - Final Volume) / Initial Volume * Reduction = (100 m³ - 50 m³) / 100 m³ = 0.5 * Percentage reduction = 0.5 * 100% = 50% Therefore, the Verti-Press will reduce the sludge volume by 50%.
