Projects
The following projects are realized or under construction:
Riyadh STP – Saudi Arabia (1,000,000 p.e.). This sewage plant comprises 4 oxidation ditches. Each ditch is provided with 6 channels and 5 aerators of 250 KW each. The aeration zones are covered completely. The oxidation ditches are designed for continuous aeration and simultaneous nitrogen removel.
Kangwha STP – Korea (40,000 p.e.). This plant comprises 2 identical lines. Each line consist of an oxidation ditch provided with 4 brush aerators 22 KW and an anoxic tank. The recirculation between aeration tank and anoxic tank is done by wall pumps.
Trivieres STP – Belgium (30,000 p.e.). This plant comprises one oxidation ditch with 2 channels provided with 2 vertical shaft aerators. The aeration zones are covered completely. The aerators are operating intermittently based on the signal of a redox probe.
