Industrial Wastewater Treatment Success Stories
Class A Industrial Wastewater Treatment Plant
Settling Time Reduced From Twelve Hours to 30 minutes!
This facility receives and treats oily wastewater from industrial clients. The water is treated with an initial oil/water separator, collected in a reaction tank where Floccin-J is used at a dosage of 325 lbs/18,000 gallons, then dewatered using a filter press. The results of the preliminary tests with just Floccin-J are shown below:

The picture of the treated and untreated water shows a drastic
improvement over the previous coagulant/flocculant chemistry.
The value of the Floccin-J is the increased throughput in the
facilities operation. Their previous process required a 12hour
settling time to be able to start the decanting process. They
now can start decanting in 30 minutes. Integrated Engineers,
Inc is providing assistance in helping with adding equipment
and processes to reuse part of the treated wastewater and
meet stringent discharge limitations as a disposal option.
