TL;DR: It is proposed that in batch or stirred tank reactors, both adsorbents can be an attractive option for dye adsorption.
763 citations
TL;DR: In this article, the potential use of Indian Rosewood ( Dalbergia sissoo ) sawdust, pretreated with formaldehyde and sulphuric acid, for the removal of methylene blue dye from simulated wastewater was investigated.
720 citations
TL;DR: In this article, the effects of adsorbent surface change, initial pH, initial dye concentration, adsorbents mass and contact time on dye removal have been determined, which indicated that PCSD and PCSDC could be employed as low-cost alternatives in wastewater treatment for the removal of dyes.

Abstract: Jaggery is a traditional concentrated product of sugarcane juice which is easily and cheaply available to the Indian rural population. Several value added jaggery based products are also very popular in large section of population throughout the country. Jaggery is a good source of minerals and nutritiants and also has various medicinal values. With the increasing demand of this nutritive sweetener, efforts are being made to develop a standard manufacturing package that will increase its productivity besides quality improvement in terms of hygiene, standardization of shape, size, and storability. The thermal and overall efficiencies of jaggery making plants are very low due to loss of thermal energy through flue gasses and un-designed constructional parameters of plant. The storage of jaggery is also a major problem. Since, it is much influenced by the contents of invert sugars and mineral salts that are hygroscopic in nature. This intends us to study the technological upgradations used for the production and preservation of jaggery in order to prioritise the required advancements. This paper gives an overview of the technological upgradation of jaggery manufacturing plants and the preservation of jaggery by using different storage and packaging methods.
