  1. Introduction. Phosphate tailings are solid wastes produced from mining and beneficiating operations of phosphate rock. About 30–40% of the raw ore is rejected as tailings during a typical phosphate beneficiation operation,,.In current practice, the generated tailings are collected and transported in paste or slurry form and disposed of in large tailings impoundments, which is costly Cited by: The calcium phosphate substance of phosphate ore are known by various name such as (Aza, ) BPL (bone phosphate of lime), TPL (triphosphate of lime), P 2 O 5 (phosphorus pentoxide) and P. The mechanism of coagulation by ultrasonic waves K. Söllner and C. Bondy, Trans. Faraday Soc., , 32, DOI: /TF If you are not the Authors contributing to RSC publications (journal articles, books or book chapters) do not need to formally request permission to reproduce material contained in this article provided Cited by:   A bio-coagulant Opuntia ficus-indica was used first time to pretreat tailings pond water.. Coagulation performance of Opuntia ficus-indica was compared with that of alum and ferric chloride.. Pretreated water had higher adsorption capacity for dissolved organics removal on adsorbent. • The settling velocity of flocs generated by bio-coagulant was significantly higher.

  Phosphorus is mainly in the form of orthophosphate, accounting for % to % of the total phosphorus content of the sludge. Phosphorus removal can be done by precipitation crystallization,. In addition, ultrasonic technology is more efficient than the microwave for the dissolution of COD in sludge.

Phosphorus, as a limiting nutrient and an essential element for the growth of organisms and plants, is an indicator of surface water quality. However, excessive point and/or nonpoint discharges of phosphate into water bodies such as lakes, rivers, and seas lead to the eutrophication of freshwater and deteriorate aquatic ecosystems subsequently, which has been occurring throughout the world. The coagulation behavior of aluminum salts in a eutrophic source water was investigated from the viewpoint of Al(III) hydrolysis species transformation. Particular emphasis was paid to the coagulation effect of Al13 species on removing particles and organic matter. The coagulation behavior of Al coagulants with different basicities was examined through jar tests and hydrolyzed Al(III.

(Virginia Polytechnic Institute, ) Lactic acid fermentation of. coagulation ofrennetted milk. The ultrasonic waves were transmitted through the milk and the coagulation process was followed after adding the enzyme. The observed changes in ultrasonic attenuation during coagulation were used to predict the coagulation time indicating the onset of coagulation. Coagulation times were also determined by measuring.   1. Introduction. The acid coagulation of milk has been extensively studied over recent years. Certain aspects of the reaction have been well established, for example that the production of acid by acidulants or by lactic acid bacteria causes the dissolution of the calcium phosphate from the casein micelles (Dalgleish and Law, , Le Graët and Brulé, ), and that pre-treatment of the.   Ultrasonic scalers are driven by generators, which convert electrical energy into ultrasonic waves via piezoelectricity or magnetostriction and are designed to facilitate scaling and root planning process ().The use of ultrasound in dentistry was proposed by Catuna () for the process of cutting teeth, further work undertaken by Zinner () showed that ultrasound could be used to .
