Sludge digestor treatment control
Among the objectives of sludge treatment is to reduce the amounts of solids to be removed, since these represent a significant cost factor for operators of wastewater treatment plants. Within this process is the optimization of their dehydration and the recovery of biogas through its digestion.
In the digester, a significant amount of foam can form at any time. We have a solution for foam detection and mitigation.
Biogas production is an indicator of the sludge digester operation for the measurement of the biogas flow is very important for the digestor control.
Conditioning sludge with lime milk (whitewash) or polymers before dehydration is the key to obtaining good results in the dehydration process and prolonging the life of the filters as much as possible.
By varying the dose of conditioning agent according to the solid matter content, not only improve the results of the dehydration process, but also the consumption of chemical products.
