How to Reduce Water Costs by 70% in Your Dyehouse
A textile dyehouse uses 100-150 liters per kg of fabric dyed. A 10-ton daily facility consumes 1,000-1,500 m³ of water.
The Real Cost of Water
| Cost Item | Approximate | |-----------|------------| | Municipal water | $0.5-1.5/m³ | | Softening/prep | $0.3-0.8/m³ | | Heating | $1-2.5/m³ | | Treatment | $0.5-1.5/m³ | | Discharge fees | $0.5-2/m³ | | Total | $2.8-8.3/m³ |
Recovered water eliminates all these costs plus energy savings.
