The unavoidable reality is that every day we consume more drinking water in cities and more agricultural resources for crops. Crops require more water and it suffers from pollution. is. agricultural fertilizerBreaking that vicious cycle is therefore a priority.that’s why Wastewater treatment A particularly exciting approach to producing compost and compost. Currently, the University of Granada and the University of Cordoba in Spain are collaborating to innovative technology This improves these wastewater treatment processes in two ways.First, this New technology solution Reduces foul odors of wastewater sludge. Second, it reduces the time required to turn them into fertilizer. Specifically, it saves him two months over traditional methods.
This technology utilizes a movable cover and membrane designed to mask the composting process. These semi-permeable membranes allow the release of carbon dioxide while containing odor-inducing molecules such as ammonia. In addition, air is injected to facilitate metabolic processes by aerobic bacteria.test of this technology project We show that this method produces high quality compost for plant fertilization.
From fertilizer to fish food
one of the pillars of circular economy We minimize waste by recycling and reusing. This is known as the zero waste approach. Thus, along with the work carried out by the Universities of Granada and Cordoba, there are other technologies under development. Efficient use of wastewater in a similar way. But this time it’s about the wastewater from the farm. It usually contains excess phosphorus and nitrogen. The approach of this innovative technology project is to design a wastewater treatment plant that utilizes the action of microalgae. The final product is aquatic feed protein.
The system is relatively simple. The tank is fitted with a bioreactor into which wastewater flows. There is sunlight It promotes the development and activity of microalgae that feed on fish manure. The microalgae are then separated from the water, dried and powdered. The resulting biomass contains approximately 40-50% protein. The cleaned water can be returned to the aquarium.
The pilot bioreactor can purify up to 5,000 liters of water every three days and produce four kilograms of fish feed in the process. Of course, the number one priority is to scale up the technology project. Our goal in the coming months is to develop a unit that can handle 50,000 liters per day, and ten times that in the long term.
