The aim of the study was to estimate effectiveness ultrasonic coagulation aiding. effect ultrasound exposure alone and associated systems (ultrasound exposure/coagulant) on contamination natural water examined. evaluation test results based changes in indicators, such as TOC, color, turbidity, electrokinetic potential. Three different coagulants were used tests systems. included basic processes...

On the basis of the sources and harm the ink wastewater analysis, summed up the four ink wastewater treatment methods: adsorption, coagulation, chemical oxidation, biological method, and the four methods were compared. He points out the advantages and disadvantages of each method and conditions of use, the treatment effect.

The process of blood coagulation in mammals is complicated, and involves the interaction of more than a dozen coagulation factors as well as a number of proteins from the kininkallikrein system and protein inhibitors. Attempts to model coagulation mathematically have previously focused on a smaller subset of interactions, perhaps one of the pathways or just a portion of one of them (cf. [1],[2]...

Fenton process, as one of the most conventional advanced oxidation processes, is widely used in the treatment of specific wastewaters, especially landfill leachate. In current study, the main target was to evaluate some neglected aspects of Fenton process in operational applications. Thus, three novel responses were introduced. Mass removal efficiency evaluates overall recalcitrant destruction ...

The natural water contamination because of the population growth, industrialization, urbanization, sewage from households, industries, institutions, and hospitals, among other things, has increased. After using in various ways, this turns into wastewater, completing hydrological cycle. Waterways that are contaminated pose numerous hazards to health environment. As a result, contaminants must be...

Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM) to reduce the formation of disinfection by-products (DBPs), is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the eff...

Pollution in river water affects human, plant and animal health activities, its removal using chemical coagulants is a huge concern. This study aims to reduce turbidity COD pollutants through coagulation-adsorption process by Tacca leontopetaloides biopolymer flocculant (TBPF) powder activated carbon (PAC). In coagulation experiment, TBPF dosages were varied evaluate the effect on Bioblock floc...
