When running a modern wastewater treatment framework, the floc that structures can once in a while coast. On the off chance that your treatment framework contains gliding floc, you realize it tends to be a test to take out. The floc really contains the contaminants that are in your wastewater, so on the off chance that it isn’t expelled before the wastewater is released, you might be out of consistence with your release license. There are numerous things that cause coasting floc. A portion of the more typical causes are portrayed beneath, alongside investigating tips that you can use to enable you to figure out what might be causing drifting floc in your framework.
Water stream that is excessively high
At the point when the water stream rate is at or close to the most extreme stream rate that your clarifier was intended to deal with, floc doesn’t have the opportunity to settle in the clarifier like it should. This can make the floc glide. On the off chance that you have as of late expanded the stream rate, have a go at diminishing it to check whether the floc settles. On the off chance that you have not expanded the stream rate as of late, you ought to research different causes.
Oxidants brought into the Waste Stream
Oxidants like hydrogen Peroxide H2O2 can make floc glide. You can direct a container test to decide if an oxidant is causing the drifting floc. At the point when you do as such, search for the floc to be at the highest point of the measuring utencil as opposed to the base. Once in a while it can take up to 15 to 30 minutes to for floc to glide. In the event that you affirm that oxidants are making the floc coast, you can include a decreasing operator, for example, bisulfate or an exclusive metal precipitant to your waste stream. You ought to counsel your xu ly nuoc thai cong nghiep administrations merchant about the best technique for adding lessening specialists to your waste treatment program.
Floc that is excessively light and excessively huge
At times, floc can turn out to be excessively feathery and lightweight during treatment. There are a few choices for revising this. You can have a go at utilizing a heavier coagulant, changing to a progressively perfect polymer, or modifying how the polymer is dosed. Changing the polymer dosing strategy can be as basic as modifying the portion rate. You can likewise change the polymer fixations that are being utilized. For instance, on the off chance that you utilize an emulsion or dry polymer at 0.3% by volume, attempt 0.15% by volume. You may likewise need to consider changing where the polymer is dosed inside the water treatment process. In some cases dosing in the last response tank notwithstanding the clarifier can forestall coasting floc.
