On 17 June 2014, Chol Abel will defend his PhD thesis on soil aquifer treatment. Prof. Maria Kennedy and Prof. Saroj Sharma will be his promotors.
This thesis showed that soil aquifer treatment (SAT) is an effective polishing technology for reuse of primary effluent. The study experimentally revealed relatively high removal of suspended solids, bulk organic matter, nutrients, pharmaceutically active compounds and pathogens indicators under various operating conditions. Furthermore, the tools and water quality prediction model developed based on laboratory, pilot and field data could be used for proper design, execution and operation of new SAT schemes. The model could be used to estimate the expected removal of contaminants and assess the need for post-treatment of reclaimed water.
