A Successful Modification to the Dorr 444 Clarifier
نویسندگان
چکیده
CFD modeling was used to design a simple modification to one of four compartments of a Dorr 444 clarifier at Maidstone. The model was validated via tracer testing but the best validation would be implementation of the modification. The modification consisting of a system of two baffles was installed during the season and results in terms of clear juice absorbances were obtained. There was a clear improvement when comparing the clear juice absorbance of the modified compartment to that of the unmodified compartment. There were doubts about the differences between flows to the compartments. Tracer testing did show that the flow characteristics between modified and unmodified compartments were similar.

Cfd Modelling of a Rapidorr 444 Clarifier: Recent Progress
Past Computational Fluid Dynamics(CFD) work on the Rapidorr 444 required a quantitative check of its accuracy. Factory tracer tests were used to validate the developed CFD model. Since the model was a function of its input, these parameters, particularly juice and mud densities were re-calculated over an entire season and average values used. In addition a new three-dimensional model of the Rap...

Nesogordonia tricarpellata Skema & Dorr, sp. nov., a new species from southeastern Madagascar, is described and illustrated. It differs from all other species of Nesogordonia Baill. in having 6-9 stamens, 3 staminodes, a 3-carpellate ovary, and a 3-valved capsule. These androecial and gynoecial characters require modification of the long-standing circumscription of the genus. The new species al...

The paper outlines a method to determine the sedimentation efficiency in modernized tanks with incorporated lamella packets. The method takes into account the properties of the suspension (density, viscosity, solid phase distribution) and tank design parameters – flow intensity and settling surface. Several types of grain size distributions are considered: the log-normal distribution and genera...
