Water reuse, salt recovery, acid and alkali regeneration, and metal recovery are the main directions for resource recovery solutions.
Resource Recovery Directions
- Water reuse reduces freshwater consumption.
- Salt recovery reduces downstream solids pressure.
- Acid and alkali regeneration reduces demand for new chemicals.
- Metal recovery retains valuable elements.
Assessment Criteria
- Whether recovered materials have a stable outlet.
- Whether purity and concentration meet reuse requirements.
- Whether impurity separation and subsequent disposal costs are acceptable.
Engineering Recommendations
Resource recovery is not simply about adding equipment. It requires evaluation of material balance, product quality, operating costs, and disposal boundaries together.
