In order to prove efficiency of solutions developed by ECOS with the purpose to double the STP capacity twice and to improve the effluent quality, the decision was made to create and to test experimental treatment facility in the South Plant and to perform its field trial. ECOS developed and submitted detailed 3D design of the trial unit.

The Arabic partner carried out manufacturing and mounting of the Trial Unit with the capacity 72 m³/day. ECOS installed its branded synthetic ERSH® filling and aeration system. After testing and commissioning the Trial Unit had been in operation for 7 months. Its operation ensured the required treatment quality and proved efficiency of process solutions developed for STP improvement. Trial Unit operation and laboratory analysis were performed by the South Plant stuff.
