Water treatment of selected water wells of Al- Muqdadiyah town-Iraq using burned initiated bentonite as a granulated Natural ion- exchanger via columnar method.

Abstract

The aim of this study was to find a general method, cheap and easy to deal with water wells. Treatment of selected water wells of  Al – Muqdadiyah town was carried out at (25­± 0.1) ºC, using natural granulated Iraqi  Na – montmorillonite clay ( initiated burned bentonite), in known flow packed columns. The Na – montmorillonite clay mineral was characterized by FT – IR spectroscopy. [Total dissolved solids (TDS), Electrical conductivity (EC), Total hardness (T.H.CaCo₃), Ca⁺², Mg⁺², Na⁺, and pH] quantification was done before and after treatment of water samples using (MI – 180 Multi – Bench meter MARTINI – Instruments). Calcium Ca⁺², Magnesium Mg⁺², and Sodium Na⁺ were measured using flame photometer [PFP7 flame photo meter from (JENWAY)], Total Hardness was measured using titration method using UniVer1 hardness reagent. The results indicated that the values of these parameters are within or lower than the international drinking  water supplies average, , and Iraq drinking water standards.
