RichWater is a EU Horizon 2020 funded project which has provided an innovative technology for wastewater reuse in agricuture. An integrated approach combining treatment and irrigation in a single system enables taking maximum advantage of nutrients.
RichWater system consists in a low-cost and energy-efficient MBR (membrane bioreactor) to produce pathogen-free and nutrient rich irrigation water.
The treatment system is connected to:
- the mixing module (for tailor-made mixing with freshwater and additional fertilizers)
- the fertigation unit
- a monitoring / control module including soil sensors to guarantee demand-driven and case sensitive fertigation.
By combining these modules, a complete and turn-key system for safe wastewater reuse in agriculture is available.
It is RichWater project ambition to develop an up-scaled commercial prototype (150 m³ treatment capacity /day) in South Spain to reuse local community wastewater for irrigation purposes.
The aim is to create a win-win situation between two sectors (the wastewater treatment and the agricultural sector) by turning public wastewater into a valuable end-product. A detailed life cycle assessment and business plan will help to precisely assess the ecologic, technological and economic benefits enabling an effective market strategy.
Main activity field:
- Production of 150 m3/day of treated wastewater (i.e. reclaimed water)
- Low energy consumption (ca. 1.5 kwh/m3)
- Irrigation of 3 target crops at experimental field: tomato, mango and avocado
- Treated water suplying 50% of main macronutrients (N,P,K) to the target crops
- Agronomic studies to compare irrigated crops irrigated with RichWater and conventional water
- Cost benefit analysis and feasibility study
- Market strategy
