Abstract

This study involves removing of Methylene blue dye (MB) using some plants material (Citrus utrantiforlial) by using batch system. The effect of dye concentrations, contact time, and adsorbent dosages on adsorption process respectively . the obtained results show that, MB dye removal was significantly enhanced with the use of adsorbent weight 0.7 mg which showed removal efficiency up to 94% . While the best contact time was 90 min with removal efficiency 94.02, and there was a reverse correlation between the initial dye concentration and the removal efficiency

Abstract

In this paper, the corrosive properties of the water treatment plants system and biological stability were clarified. Several studies and dissertations published in this subject were reviewed in this paper. The problem of corrosion was explained and the reasons for their occurrence, Methods are used to reduce this characteristic, water stability and the factors affecting corrosion, Stability and correlations, which included five indicators: Langelier Saturation Index (LSI) ,Ryznar Stability Index (RSI), Puckorius Scaling Index (PI, Larson–Skold Index (LS), Aggressive Index (AI).
