The spinning disc (SD) technology has been used for a number of applications due to its improved attributes. This study focuses on applying SD technology to a textile wastewater treatment in order to improve, without any other additional treatment, its suspended solids and color contents. An experimental planning based on a central compositional rotatable matrix of 23 order is used for modeling. Also, the optimal values of all considered process variables (independent ones: flow rate (z1) within 10-30 L/h experimental range, disc rotational speed (z2) in 200-1100 rpm range, operating time (z3) within 5-30 min range) were established together with the dependent ones: treatment degree of suspended solids content (Y1) and discoloration (Y2). The SD treatment feasibility was reasonably good (max. Y1 = 45.07% and Y2 = 26.59%). Thus, it can minimize color and solids loads within a relatively short time period and can be used within the primary treatment step. |
