Manufacturing Wastewater Treatment Case Studies
Metal Processing Facility Wastewater Treatment Test
Wastewater Treatment Procedure:
- Mix samples with regular and chrome laden stream to obtain a 7% by volume chrome to regular wastewater blend. Used a 2,000 ml sample.
- Initial pH = 9.5, Conductivity = 3,4250 uS, ORP = +55.9 mV.
- Add IE-061 (10% solution) for a total of 0.3ml of neat product to an ORP of -163 mV.
- pH still at 9.5, added Carbon dioxide gas to a pH of 7.0 Sample was buffered at 8.3 so it took a fair amount of carbon dioxide to drop through to 7.0.
- Added Floccin™ HP at 38 grams/2,000 liters (160 lbs/1,000 gallons).
- Total addition of IE-061 was 150 ppm, Carbon Dioxide usage estimated at 20 lbs. per 1,000 gallons.
