In wastewater treatment, dewatering is the process of reducing sludge volume and converting it from a liquid slurry to a solid product. The methods used to dewater wastewater sludge are varied, but two of the most common are belt filter presses and centrifuges. Effective sludge dewatering is key to minimizing labor, power, hauling and
This article reviews the optimization of the final drying technology in conjunction with the upstream continuous solid-liquid filtration, cake washing, and dewatering technology. This article illustrates that by taking a holistic approach and looking at each step not individually but as a continuum, the process solution becomes much more efficient.
Simulation and Optimisation Methods Optimal mine dewatering design requires a physically based and calibrated groundwater flow model to simulate drawdowns, the objective function, well defined management and technical constraint specifications, and an optimization approach.
