Sedimentation Process

The design and operation of floc blanket clarification plant, embodying coagulation, flocculation and floc blanket sedimentation is still very much an art, mainly because there has been no adequate scientific explanation of the mechanisms of the floc blanket sedimentation process. This study aims to provide an explanation based on the floc blanket formation with CPL (hydroxyl chlorine of aluminium) coagulant. The theoretical parameters results were: Gcoagulation: 1,500 s-1; Gflocculation: 397 s-1, and for sedimentation G×θ×c 2476.8. The solid removal in the floc blanket was 65.28% expressed by residual turbidity. The water quality obtained at the end of the treatment satisfied the values of official Mexican standards.

The paper reports the results of Chlorella vulgaris sedimentation process including description of cultivation condition of microalgal biomass. The process of algae cultivation was carried out in photobioreactor comprising systems of carbon dioxide supply, mixing and artificial LED illumination. The growth of microalgae was determined alternatively in three ways by measuring the amount of dry mass over time, counting the cells and measurement of optical density by use of a spectrophotometer. Algae biomass with different concentration was subjected to the separation process by gravity. This led to the determination of the characteristic of sedimentation process for different concentrations and cell sizes. The experimental results indicate that sedimentation process offers a tool with a potential application for microalgae harvesting.

AbstractIn order to model the dispersal of volcanic particles in the atmosphere and their deposition on the ground, one has to simulate an advection-diffusion-sedimentation process on a large spatial area. Here we compare a Lattice Boltzmann and a Cellular Automata approach. Our results show that for high Peclet regimes, the cellular automata model produce results that are as accurate as the lattice Boltzmann model and is computationally more effective.

Aerated Filter

Using coagulation and sedimentation process in the advanced treatment of urban secondary effluent which can be recycled to circulating cooling water system in power plant is only perform well on CODCrand turbidity removal. But the concentrations of organic matter and NH3in effluent can not meet the requirements of circulating cooling water. Therefore, in this study, the feasibility of biological aerated filter (BAF) as a pretreatment enhancing coagulation and sedimentation process was discussed. Achieved by controlling the two operating modes: (1) secondary effluentcoagulation and sedimentationeffluent; (2) secondary effluent BAFcoagulation and sedimentation effluent.The results show that the BAF pretreatment removes ammonia nitrogen effectively, and the turbidity and CODCrof effluent of BAF-coagulation sedimentation process is much lower than individual coagulation and sedimentation process. The final effluent qualities meet the requirements of circulating cooling water system in power plant.
