Use of Natural Materials for Wastewater Treatment & Improvement of Water Quality

Abstract

In the present work the results of purposeful researches are submitted in the field solutions and waste water of application natural zeolites, tuff and agricultural by-products as sorbents for removal of ammonia and organic substances from water. The abundance and availability of zeolites, tuff and agricultural by-products/the by-products include soft lignocellulosics such as apricot and peach seeds, also mentioned seeds based activated carbon/make them good candidates as sorbents for waste water treatment. Technological stability of zeolites as sorbents is determined by such characteristics as mineral - their low cost, their availability, chemical composition, sorption ability, mechanical and physical properties, and then filtering properties. Adsorption by agricultural by products is preferred because of its have low sensitivity to flow fluctuations and exhibits greater flexibility. In other case activated carbons also is preferred because of its large surface areas resulting in higher separation efficiency by activated carbons. The advantages of agricultural by-products in comparison with other sorbents are their low cost, availability of extraction, operational flexibility and control. © Springer Science+Business Media B.V. 2011.
