Existing wastewater treatment plants have following needs:
▪ Treatment capacity – growing population, increaseconnection rate
▪ Effluent quality – re-use for irrigation
▪ Check in needs for • refurbishment of existing equipment
• expansion (new tanks, new technologies e.g. MBBR)
Actual Situation

Challenges:▪ comparable higher investment costs▪ proper design of components & system integration▪ Skills of operational staff
Chances:▪ high quality effluent (re-use agriculture)▪ digestation o sludge reduces load to biological treatment of 1/3▪ energy efficient operation & very low carbon footprint▪ sustainable investment
