Abstract
In engineering design, knowing the relationship between the means (technique) and the end (desired function or outcome) is essential. The means in Aquaculture are technical solutions like airlifts that are used to achive desired functionality (an end) like controlling dissolved gasses. In previous work, the authors identified possible functions by viewing aquaculture production systems as transformation processes in which inputs are transformed by treatment techniques (means) and produce outputs (ends). The current work creates an overview of technical solutions of treatment functions for both design and research purposes. A comprehensive literature review of all areas of technical solutions is identified and categorized into a visual taxonomy of the treatment functions for controlling solids, controlling dissolved gasses and controlling pH alkalinity and hardness. This article is the second in a sequence of four and partly presents the treatments functions in the taxonomy. The other articles in this series present complementary aspects of this research: Part 1, A transformational view on aquaculture and functions divided into input, treatment and output functions; Part 2, The current taxonomy paper; Part 3, The second part of the taxonomy; and Part 4, Mapping of the means (techniques) for multiple treatment functions.
Highlights
The role of aquaculture is becoming more important as a solution to feeding an increasing planet population
Recirculating systems are closed systems that offer a high level of security and control over the environment the fish grow in, maximizing their potential to achieve the highest growth and survival rates
The main aim of this work is to map out all the known technical solutions to each treatment function, describe them briefly and lay out a taxonomy of technical solutions
Summary
The role of aquaculture is becoming more important as a solution to feeding an increasing planet population. With limited freshwater supply and increased emphasis on the conservation of marine waters, utilizing the water resources in the best way possible is key. Recirculating aquaculture systems are designed to treat and recirculate the process water, minimizing the amount of water intake and maximizing waste management and nutrient recycling [1]. Recirculating systems are closed systems that offer a high level of security and control over the environment the fish grow in, maximizing their potential to achieve the highest growth and survival rates. They are constructed out of multiple modules (subsystems), each designed to control specific water quality parameters
