Water treatment generates several by-products consisting mainly of sludge. At a time when landfill admission conditions are strengthening, the quantities of waste sludge from factories are only increasing. The combination of these two factors poses significant challenges for the future, and makes it imperative to control the fate of sludge. The evaluation of physicochemical parameters of sludge constitutes a vast field of action and a heavy responsibility for factories. On the one hand, it is necessary to limit the cost on an economic level while protecting the environment by developing solutions that can minimize nuisance. To this end, our work aimed to evaluate the physicochemical parameters (hydrogen potential (pH), electrical conductivity (EC), dryness, humidity, nitrate ion) of the sludge at the level of the Lukaya water treatment plant in Mont-Ngafula. The results obtained prove that the sewage sludge from the Lukaya Plant benefits from pre-treatment inside the plant before being released into nature, where the environment will not be contaminated after excrement. of this sludge in nature. He results showed neutral pH contents ranging from 8 to 8.2 in the 3 samples analyzed, thus proving that these sludges have acceptable pH contents because the required average is between 7-8 for sludges disposable in the environment. The electrical conductivity remained in the range of 16 and 17 mS/cm, it is well below the standard which requires it to be between 200 and 800 mS/cm. itrate levels remain below 50 mg/L in all samples analyzed, which makes this sludge low in nitrogen. He dryness tells us that it is solid sludge because it is between 67 and 68%, which ipso facto implies a low moisture content of around 75%. Thus, in view of these results, our study concludes that the upstream treatment of the sludge by the plant is effective and needs to be strengthened in order to further stabilize the physicochemical parameters of this sludge, in this case the conductivity. Electrical and nitrate content before release into the environment. This is how recommendations aimed at strengthening upstream treatment efforts for sewage sludge by the plant were also formulated.
