Effluent Water Load
BOD/COD comparison of water-soluble polymer compounds
| Resin | COD (mg/kg)×10⁴ | BODg(mg/kg)×10² |
| GOHSENOL™ | 60~100 | 50~100 |
| Cornstarch | 36 | 7400 |
| Sodium polyacrylate | 3.1 | 95 |
| Polyethylene glycol (PEG600) | 76 | 6.3 |
| Polyethylene glycol (PEG1500) | 76 | 3.1 |
| Polyacrylamide | 6.8 | 76 |
Measuring conditions: Sample concentration = 0.1%
COD was measured by the potassium permanganate method (JIS K 0102), and BOD5 is the 5-day BOD value.
Measurement: Registration No. of measurement certification business: Osaka No. 10013, KK Osaka Environmental Technology Center
