A Spanish research institute, located in Madrid, has developed an optimized land application system that considers the environment and the socio-economic aspect for the treatment of urban and industrial wastewater. For each application, the system is specifically designed and adapted to real needs. The control and management can be carried out by implementing information and communication technologies (ICTs). Looking for commercial agency agreements.



The Spanish research institute located in Madrid has developed a land application system which are ecological non-conventional wastewater treatment technologies in line with EU research and innovation policy agenda on nature-based solutions and re-naturing cities. These eco-technologies represent a very interesting solution for the treatment and management of wastewater from small municipalities that require low installation, operating and maintenance costs. They can also be considered for the regeneration and reuse of treated water from a secondary or tertiary process. Under certain conditions, the use of land application systems can mean an improvement in environmental management systems and corporate social responsibility, encouraging the sustainable use of resources, the circular economy and the protection of the environment.
Briefly, a land application system is a plot area, sized according to the influent to be treated, where a plantation is irrigated with wastewater. Part of the applied water evaporates, another part is absorbed by roots and the rest infiltrates in soil, recharging the underlying aquifer. The water treatment is produced by physical, chemical and biological processes that take place by the joint action of soil, microorganisms and plants. In certain cases, a primary treatment system, to remove coarse solids before application to the soil, would be advisable.
These systems provide more than just simple treatment because while treating water, they are also producing biomass with high economic value. Numerous functions and ecosystem services are also provided, such as aquifer recharge, ecological niche, carbon sequestration, and landscape improvement, among others. Unlike conventional wastewater treatment systems, no external energy input is needed, so the operating and maintenance costs are greatly reduced. Furthermore, it is a robust technology and the operation is very simple. These eco-technologies are therefore ideal for the treatment of urban wastewater from small towns that cannot effort conventional wastewater treatment technology and has strong flow oscillations (between winter and summer period).
The research institute is looking for industries (textile, agri-food, etc) and small municipalities for the design, implementation and/or monitoring of optimized LASs, as wells as companies from the chemical, environmental, agri-food and ICTs sectors to reach commercial agency agreements to improve both design and monitoring.

Advantages & innovations

Cooperation plus value: 
Land Application Systems (LASs) are reliable, robust and low maintenance eco-technologies. This, together with the moderate cost of implementation, makes LASs very competitive technologies for treating wastewater. Systems provided by the research institute improve other similar non-conventional technologies by a site-specific design and using different innovative strategies: •Circular economy: Low-cost amendments resulting from the prune of trees are reused in the system (waste residues are converted in products). These amendments have been proved to maximize the removal of nutrients and emerging contaminants. Furthermore, nutrients from wastewater are recovered and used by plants to produce biomass. •Small area and performance: LASs with a high-density plantation (up to 10,000 stems per hectare) maximize treatment while reducing the required area. •Extra economic value: Short wooden cutting cycles (less than 3 years) are planned. The biomass produced is a by-product of commercial value that reduces the final operation and maintenance costs. •Specificity: LASs are always designed to deal with the treatment of site-specific effluents of industrial and urban origin that are not viable to be treated by conventional systems. They are a multidisciplinary team of experts in environment, hydrogeology, water and soil quality, and transport of pollutants, and they are able to propose solutions on demand.
