Experimental study of treatment in a sedimentation tank to minimise the suspended solids

It is common practice for cooling water systems in power plants to include a sludge tank to collect sludge and slurry. This research focuses on the development of a model that can be used as an aid in the design, operation, and modification of a settling tank, and the simulation of a sludge tank design in flow-through mode as a settling tank for suspended solids from cooling water systems. The purpose of this study is to investigate and understand the use of a sedimentation tank for cooling water system treatment to minimize SS through simulation. The research methodology was to determine, under laboratory conditions, the particle settling capacity and clarification performance in a settling tank: settling time, sedimentation rate, settleability, and productivity for a settling tank. The granulometric composition of the suspended solids was investigated to determine the circularity factor, the sphericity of the different types of particles, and the solidity of the suspended solids. Thus, the introduction of water treatment with a sedimentation tank with the geometric parameters used in this study will make it possible to remove up to 560m 3 of suspended solids per quarter from the cooling water system.
