THE ALUM WITH AUSTRALIAN PORCELANITE ROCKS EFFECT ON TREATING AND REMOVAL OF PHOSPHORUS FROM DAIRY WASTEWATER

Abstract

The dairy industry is a vital food industry in the world. The dairy industry discharges large quantities of wastewater. In this article, it has been used jar test model JLT 6 Leaching test VELP Scientific, with all apparatuses and tools that can complete work. Alum, as well as Porcelanite Rocks from the North Territory area in Australia, were used as a treatment material for the removal of phosphorus. Results showed the effectiveness of phosphorous removal using alum improves when using these rocks because they contain different concentrations of positive ions in general and aluminium ions in particular. The optimum value of Al3+ is 0.5 mg/L. The percent of removal of phosphorus will reach 95.7% ̴ 96% by 1.45 mg/L of the aluminium ion. The use of Porcelanite Rocks alone. cannot lead to clear removal of phosphorous or pollutants, rather it is used as an aid. The results also showed that Porcelanite rocks play a prominent role in preparing the therapeutic conditions for alum in terms of regulating the pH for better treatment, as they raise the pH at a time when the sulphates are reduced. With 20 mg/L of Porcelanite rocks, it has been completed the best removal of phosphorus at 20 ºC. Using alum with Porcelanite rocks as assistance in treatment will improve treatment by 30-40%. This process will drop residual aluminium concentration by about 10% from the total and then exclude health effects due to aluminium ions.
