Scenario: A wastewater treatment plant produces 100 tons of sludge per day. A Draimad system is installed to dewater the sludge, reducing its moisture content from 80% to 50%.
Task:
1. **Before dewatering:**
Volume = Mass / Density = 100 tons / 1 ton/m³ = 100 m³
2. **After dewatering:**
The moisture content reduces from 80% to 50%, meaning the solid content increases from 20% to 50%. Therefore, the mass of solids remains constant at 20% of the initial mass (100 tons x 0.20 = 20 tons). Now, the solids represent 50% of the dewatered sludge.
Mass of dewatered sludge = Mass of solids / Solid content = 20 tons / 0.50 = 40 tons
Volume of dewatered sludge = Mass / Density = 40 tons / 1 ton/m³ = 40 m³
3. **Percentage reduction:**
Percentage reduction = ((Initial volume - Final volume) / Initial volume) x 100% = ((100 m³ - 40 m³) / 100 m³) x 100% = 60%
Therefore, the Draimad system achieved a 60% reduction in sludge volume.
