Tuning of Controllers Developed for Oil Biodegradation Constructed Wetland

Deia Eldin Osman Hagahmed, Gurashi Abdallah Gasmelseed, and Siddig Eissa Ahmed
Abstract—Constructed Wetlands is a method of treatment of waste oil contents in water produced from oil fields. The method of treatment is found to be efficient and could reach greater than 90% biodegradation if it is properly controlled. The case study proved continuous good performance. Besides, a need for good automatic control appears as other challenges facing sustaining the system performance with manual operation. In this work, the controlled variables are water level in lagoon No.1 and the oil content in the effluent from Reed Bed No.1. The primary controller through measurements of effluent oil content cascaded with the level controller of lagoon No.1 with subsequent changes in set point whenever required. A control strategy was developed and the relevant transfer functions were identified through transient material balance. The overall transfer functions were calculated and characteristic equations for both closed and open loops were determined. From those transfer functions, the systems controllers were subjected to tuning techniques, and simulation response using MATLAB software.

Index Terms—Constructed wetlands, tuning, controller, produced water.
