Industrial Wastewater Treatment – Eliminating Floating Floc

When running the industrial wastewater treatment systems, floc shape sometimes floats. If your care system contains a floating floc, you know it can be a challenge to remove. Floc contains contaminants that exist in your wastewater, so that if it is not removed before the wastewater is removed, you may be out of compliance with a permit to discharge you.

Many things cause a floating floc. Some of the more common causes are described below, along with troubleshooting tips that you can use to help you determine what may be causing the floating floc in your system. You can also install industrial wastewater treatment plant to manage industrial wastewater.

Water flow is too high

When the water flow rate is at or near the maximum flow rate that your clarifier is designed to handle, floc does not have time to settle in the clarifier as it should be. This can cause the flock to float.

If you just increase the flow rate, to try to reduce to see if the floc settles. If you do not increase the flow rate recently, you should investigate other causes.

The oxidant is introduced to Waste Stream

Oxidants such as hydrogen peroxide (H2O2) can cause the flock to float. You can do a jar test to determine whether or not an oxidant that causes floating floc. When you do, look for floc which is at the top of the glass rather than the bottom.

Sometimes it can take as long as 15 to 30 minutes to flock to float. If you confirm that the oxidant that causes the flock to float, you can add a reducing agent such as bisulfate or metal precipitate exclusive to your waste stream.

You should consult wastewater treatment services your vendor about the best procedure for adding a reducing agent to your waste treatment program.
