| Abstract | ||
| The system of treatment depends on studying properties of material found in Iraqi environment called Siliceous Rocks. Laboratory analyses showed that materials were free of any harmful substances to consumers. These materials were used with and without alum for treatment raw water have different artificial turbidities ranged between low and high turbidity. Results indicate improvement in turbidity removal about 35% when using Porcelanite Rocks with aluminum ion for treated samples have medium and high turbidities (60, 120 NTU). Also contributions of positive ions were stated in treatment water through different mechanisms, the percent of missing of calcium ion was 50%. There was an increase in pH on addition of small amount of Porcellanite Rocks that will shift pH to optimum limits (7-8) for operation of Aluminum Hydroxide | ||
