Electrochemical Solutions for Environmental Remediation
Business Cases
Chemical industry
- Liquid waste generated: 3.000 T/a
- Characteristics of the waste: toxic waste with 80,000 mgO2/l of COD
- Initial treatment; external incineration
- Electrochemical treatment “in situ”. e-EOTph + w-MET
| FORMER TREATMENT | COST / YEAR FORMER TREATMENT | ANNUAL COST OF WASTE | NEW TREATMENT | COST / YEAR NEW TREATMENT | ANNUAL COST OF WASTE AND % MINIMIZATION | COST OF THE TREATMENT PLANT | AMORTIZATION OF THE PLANT BY REDUCTION OF COSTS |
|---|---|---|---|---|---|---|---|
| LIQUID WASTE AND EXTERNAL MANAGEMENT TOTAL | – | €1.200.000/year | e-EOTph+RO | €108.000/year | €0/year Minimumo -100% | €650.000 | 8 months |
Automotive industry
- Total water flow to be treated: 70m3 / h; 26,000m3 / a
- Waste characteristics: wastewater from paint booth
- Initial treatment: physical-chemical with ferric chloride and lime
- Treatment proposed: Electrochemical e-ECT + w-MET
| FORMER TREATMENT | COST / YEAR FORMER TREATMENT | ANNUAL COST OF WASTE | NEW TREATMENT | COST / YEAR NEW TREATMENT | ANNUAL COST OF WASTE AND % MINIMIZATION | COST OF THE TREATMENT PLANT | AMORTIZATION OF THE PLANT BY REDUCTION OF COSTS |
|---|---|---|---|---|---|---|---|

Pharmaceutical industry
- Total water flow to be treated: 200m3 / day. 60,000m3 / a
- Flow of liquid waste to be treated: 5,000m3 / a
- Waste characteristics: high organic load
- Current waste treatment: external management
- Water treatment: physical-chemical with ferric chloride and lime + aerobic biological
- Treatment proposed: Electrochemical
- Wastewater: e-ECT (replaces current physical-chemical treatment)
- Liquid waste: pre-treated using w-EVT + e-EOTph. Water undergoes biological treatment.
