Wastewater Treatment Success Stories

Groundwater Remediation

This sample is representative of the ground water that contains diesel fuel from years past. The facility currently uses traditional coagulation/flocculation prior to carbon filters. The objective is to reduce the organic load to the carbon filters to extend life of the carbon filter.

The treatment was performed with the addition of Floccin-J at a dosage of 0.25 grams in 1,000 ml. The treated water was then filtered and sent off for analytical testing. The analytical results are as follows:

Constituent Method Untreated (mg/L) Treated (mg/L)
Hydrocarbon Oil & Grease EPA 1664 ND ND
Total Oil & Grease EPA 1664 2.0 ND
TPH as Diesel EPA 8015(M) 940 290

The reduction in oil & grease as well as diesel shows that the Floccin-J removed a majority of the organics. The photos below show the jar tests (note the reduction in color between untreated (yellowish) and treated (colorless).

The second set of pictures is the settling rate test as the treatment process uses a lamella plate settling clarifier after coagulation/flocculation. The quick settling characteristics of the Floccin-J is almost twice as fast as conventional chemistries.

Industrial Wastewater Treatment Lamella Plate Settling Clarifier after Coagulation Flocculation Immediately after introduction of flocculating agent Floccin™
Time = 0 seconds
Industrial Wastewater Treatment Lamella Plate Settling Clarifier after Coagulation Flocculation Five Seconds after introduction of flocculating agent Floccin™
Time = 5 seconds
Industrial Wastewater Treatment Lamella Plate Settling Clarifier after Coagulation Flocculation Ten Seconds after introduction of flocculating agent Floccin™
Time = 10 seconds
Industrial Wastewater Treatment Lamella Plate Settling Clarifier after Coagulation Flocculation Fifteen Seconds after introduction of flocculating agent Floccin™
Time = 15 seconds
