Study of White Cement Quality Produced by Sanitary Wastewater from Wastewater Treatment (Case study: White Cement Factory of Neyriz)

Disposal of effluent from wastewater treatment and reuse it is, one of the important issues in the collection and wastewater treatment industry. In this study, white cement has been produced by wastewater after treatment. For this purpose, wastewater has been gathered from first settling; second settling tank, sandy filter and final wastewater effluent. Actually, 116*40*40 mm rhomb models have been made. The wastewater has been used as mixing water. Bending strength compression 3, 7 and 28 days has been measured. In all experiments except quality of mixing water, other conditions were constant and the same. Therefore using wastewater on bending strength of 3 day has not effect. Actually, effect of impurities in the waste water and resistance to bending and compression 7 and 28 days were more tangible than 3 days bend in resistance. Actually, using industrial treatment wastewater to prepare white cement can be recommended.
