Project and methodology directives for the implementation of a sustainable aquaponic system

Abstract

With the worldwide population growth, the search for technological innovations that increase food production without compromising the environment is imperative and constitutes an important theme discussed in the Sustainable Development Objectives. In this scenario, aquaponics, which associates vegetable production with fish production, stands out, contributing to sustainable development, as it improves food production, promotes food security, guarantees the availability and sustainable management of water and ensures However, the effectiveness of the system depends on energy-consuming pumps and aeration mechanisms, which are characterized as a sustainable hindrance to the technique. The objective of this research will be to propose a pilot aquaponics system for a Higher Education Institution, seeking sustainable alternatives for energy maintenance. The project proposes the construction of an aquaponics laboratory with 80 m², consisting of a tank for the cultivation of tilapia destined for consumption and of colored carp, grown as ornamental fish, horizontal and spiral hydroponic channels for the cultivation of different spices, vegetables and fruit, a biological filter tank flooded with expanded clay and papyrus cultivation, a system for pumping effluents to the hydroponic gutters, powered by photovoltaic energy, an aeration system, powered by wind turbine; the water that will feed the system will come from the rainwater harvesting cistern of the institution. It is hoped, with this proposal, to refer to the implementation of energy-efficient aquaponics systems.
