إزالة الفوسفور من المياه باستخدام كربونات الكالسيوم و كبريتات الكالسيوم المائية (الجبس)‎

Abstract EN

Decreasing water in local conditions had to search for support sources of the national water reservoir, through disposal of treatment sewage water to the rivers and water channels, with conform it to standard specifications of allowable wastewater discharge to the environment of water recipient bodies /3474/ in Syria, particularly phosphorus compounds, which is required phosphorus concentration in standard specifications (as phosphate ions) is 6 mg/l.

so research purpose has been to completing treatment of this water, and reduce phosphorus compounds in treated water for prevention of eutrophication problem in water resources.

that's by steps of practical research, by test some chemicals, because of lime, iron and aluminum compounds are expensive (which are generally used internationally to this aim), chemicals as calcium carbonate and gypsum are tested which are cheap and available in Syria by add them to secondary treated wastewater, each separately, and then together, later study efficiency of phosphorus removal during use each of additions.

by comparing results, it can be known the best way of phosphorus removal from water which has best efficiency.

all that after testing several rates of chemicals, and choose best efficiency.
