The oxidation ditch configuration based wastewater treatment plant in Spain required a quick upgrade in order to comply with new inflow and quality requirements.
Requirements
The existing plant was operating with two parallel Oxidation Ditch modules with a flow rate of 600 m³/d each, and exhibited very poor nitrification capacity. The plant was to be expanded (at the final stage) to treat a total of 2,400 m³/d t and to achieve the
Client: Municipality of Yavne, Israel

Moving bed type reactors are bio-film processes utilizing small, plastic biomass carriers that mix in the water. The use of biomass carriers is becoming common world-wide, for many applications, some of which are: compact low operation units, industrial wastewater roughing filters, retrofit and upgrade of municipal wastewater treatment plants. The AGARTM Process (Attached Growth Airlift Reactor) belongs to this category, with the addition of: airlift-based mixin
