Abstract:
The aim of this study is to develop a hybrid process which combines with coagulation, flocculation and flotation process in a hydroclone for water treatment process. The development is concerned with the hydrodynamics characterization and the water treatment optimum condition determination. The hydrodynamics characterization study is carried out by the numerical simulation (Computational Fluid Dynamics) and experimental work by Doppler ultrasound velocimetry technique to study the hydrodynamics for the further research. The results are used for validating the oil droplet experimental technique and to be the basis knowledge to explain the phenomena in the hybrid process. Laser diffraction technique is involved for determining the micro bubbles size and also study on the parameter affects to the size. The experimental work of a developed hybrid pilot plant is studied with synthesis raw water and natural river water. The objective of this study is to apply this hybrid process for the water treatment. The parameters have been varied in many operating conditions to indicate the separation and the water treatment phenomena such as raw water characteristic, coagulant - flocculant type and concentration, air fraction and inlet flow rate
