Key Findings
- 01Coagulation and Fenton processes generated excessive sludge and did not meet reuse standards.
- 02Photo-Fenton and BF achieved high turbidity and COD removal, but BF effluent required GAC post-treatment for COD.
- 03Photo-Fenton met reuse criteria but was significantly more expensive (€6.72/m³) and environmentally impactful.
- 04BF + GAC met reuse criteria, was substantially cheaper (€0.71/m³), and had lower environmental impacts.
- 05Reagent acquisition was the primary cost and environmental burden for both photo-Fenton and BF + GAC.
Application
Design takeaway
When designing systems for industrial wastewater treatment, opt for a multi-stage approach that leverages biological processes and physical filtration (like GAC) for a more sustainable and economical outcome compared to advanced oxidation processes alone.
How to apply
When designing or specifying wastewater treatment systems for laundries or similar industrial settings, evaluate the combined performance, cost, and environmental footprint of biological filtration coupled with GAC filtration as a primary treatment strategy.
Project actions
- 01When researching treatment methods, look for studies that compare multiple approaches using both performance and environmental/cost metrics.
- 02Consider the entire lifecycle of a treatment system, not just its immediate operational effectiveness.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Direct comparison of multiple treatment methods.
- +Inclusion of cost and life cycle assessment for a holistic view.
