Urea granulation is favored over prilling due to the problems associated with prilling. Tumbling agglomeration technique is employed in pan granulator. Product with wide size range can be produced by playing with only few parameters like binders (water and urea solution), ratio of binders, rpm of pan, granulation time and angle of inclination. Urea granulation is studied at laboratory scale usi...

Precipitation and accumulation of calcium phosphate in granular sludge has attracted research attention recently for removal recovery from wastewater. This study investigated granulation stage to steady state by forming heterotrophic granules at different COD/N ratios 21 32 °C, respectively, followed the transformation partial nitrifying granules. It was found that mature accumulated around 60–...

background and purpose: disposing sludge from industrial wastewater treatment plants (iwwtps) is a serious issue because it can affect human and animals health, and also environmental quality. in this study, sludge from an iwwtp was analyzed regarding its physicochemical characteristics and disposal options. materials and methods: grab sampling was used to collect 12 sludge samples biweekly (ma...

In this paper, we discuss the potential applications of data mining techniques for the design of Web based information retrieval support systems (IRSS). In particular, we apply clustering methods for the granulation of different entities involved in IRSS. Two types of granulations, single-level and multi-level granulations, are investigated. Issues of document space granulation, query space gra...

Activated sludges are an inoculum source commonly used in biodegradation studies, as wastewater treatment facilities constitute an entry point to the environment for many chemicals. In this paper, the main issues relating to the use of activated sludge in biodegradability tests are presented. Special attention is also devoted to discussing the factors affecting both the activity of the microbia...

The present disposal routes of sewage sludge represent a critical environmental issue in Egypt. Recently, there has been an increasing concern about sewage sludge management due to the environmental risks, which resulted from the fast expansion of wastewater treatment plants without equal attention in dealing with the produced sludge. This paper discusses the current situation of sewage sludge ...

The objective of the present investigation was to design suitable Immediate release tablet formulation of Aceclofenac by using cross carmellose sodium as super-disintegrant in four different concentrations i.e., 0, 4, 6, 8% w/w of tablet weight by two granulation methods i.e., Wet and melt granulation methods. The objective of the research was to compare the two granulation methods i.e., wet an...

Data granulation is considered a good tool of decision making in various types of real life applications. The basic ideas of data granulation have appeared in many fields, such as interval analysis, quantization, rough set theory, Dempster-Shafer theory of belief functions, divide and conquer, cluster analysis, machine learning, databases, information retrieval, and many others. Some new topolo...
