water is an acid
If the performance of removal for put on hold solids does not typical 40-50%, or FIGURE averages of 20-30%, over a prolonged amount of time, search for disturbance in the basin or other operational deficiencies. An additional clarifier is indicated to not just work out the solids and allow clear water to flow over the weirs, however it is likewise meant to be a thickener. It’s function is to thicken the organic solids for 2 reasons. To be able to return several of the solids back to the aerated portion of the system for more BOD destruction, however to additionally thicken the solids to ensure that dewatering is simpler. By thinking about the clarifier as an extension of the Aeration Basin, where proceeded biological destruction and also final sprucing up of the water as well as bacterial floc takes place, the system could be enhanced much easier. Polymer usage in a secondary clarifier can be reduced dramatically or eliminated with the right optimization.
