الملخص

The system of treatment depends on studying the properties of material found in the 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 has different artificial turbidities ranging between low and high turbidity. Results indicate improvement in turbidity removal by about 35% when using Porcelanite Rocks with aluminum ion for treated samples that have medium and high turbidities (60, 120 NTU). Also, contributions of positive ions were stated in the treated water through different mechanisms, the percent of missing of calcium ions was 50%. There was an increase in pH with the addition of the small amount of Porcellanite Rocks that will shift pH to optimum limits (7-8) for the operation of Aluminum Hydroxide.
