抄録

Authors have been studying the development of a new method of waste water treatment by hetero flocculation with fluorite as a solid flocculant, and further investigations on flocculation phenomena were made using quartz and fluorite particles which are negatively and positively charged respectively in distilled water.In this study magnetic stirrer and ultrasonic wave were used to clarify the influence of the method of sample preparation on quartz and fluorite particles, which contained large and small proportion of fine particles respectively, and their mixtures. It was found that quartz particles prepared with ultrasonic wave existed under the condition of primary particles in any proportion of fine particles at all pH range, while clusters of fine particles could be observed in using magnetic stirrer. When fluorite particles containing high proportion of fine particles were prepared with magnetic stirrer, the similar phenomena could be seen at pH < 10 and the number of homo-flocculated flocs decreased in comparing with that of ultrasonic wave at pH > 10 . In case of the mixture of quartz and fluorite particles containing large proportion of fine particles, the number of hetero-flocculated flocs increased enlarging the maximum size of floc at pH range of 3 - 10 when ultrasonic wave was used. And it was noticed that hetero-flocculation did not occur between clusters of fine particles and fine particles.
