REMOVAL OF PO43- BY DIRECT CONTACT MEMBRANE DISTILLATION FROM DAIRY WASTEWATER

The dairy industry is one of the basic industries that are important for the sustainability of life and because this industry uses and consumes a lot of water to produce milk, it discharges a lot of waste water. Because of the acute shortage of water needed to meet domestic, industrial and agricultural needs and increase pollution on the other, and of high fresh water demand in recent years, therefore; treatment of wastewater present very important. The most important pollutants of dairy wastewater discharged are phosphate. The present paper offers an ability of membrane distillation process (MD) for the treatment of dairy wastewater and removal of phosphate in Iraq. Artificial samples of wastewater prepared to implement the proposal. Opinions will be considered to make these wastewater samples within the standard properties of world dairy wastewater classifications. To alleviate membrane disturbances by organic and inorganic substances applied to physical deposition. The results showed the ability of the MD to remove a high concentration of phosphate from wastewater from dairy wastewater, with a clearance rate of 95 per cent. This value affected by temperature and temperature affects the effectiveness of The MD and is directly proportional to the flow.
