“…Membranes have been tested for controlling colloidal particles (30 nm-1 µm) in reuse systems [37]; they can reduce turbidity and potentially be used for advanced water treatment in recirculating aquaculture systems where extra high water quality is needed [38]. A challenge with membranes is that particles form a cake layer and the pores are clogged by colloidal particles.…”

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.

“…Biofouling, caused by dissolved and submicron colloidal particles in the system, can also become a problem in membranes. To control this issue, air-scouring and periodic backwashing and relaxation techniques are used [37]; chemical cleaning needs to be used occasionally as well [38].…”

“…Chemicals (polymers, alum or a combination of both) can be added to increase coagulation/flocculation of fine particles, increasing their size and settling speed [9], making them easier to remove. Membranes can reduce turbidity and potentially be used for advanced water treatment in recirculating aquaculture systems, i.e., microorganisms where extra high water quality is needed [10]. Bead filters offer both biofiltration and solid capture.…”

Designing aquaculture production units will require decisions on which treatment to include, e.g., the intensification of the system, and then a decision on a technical solution for each treatment function selected to implement. To complicate matters, each technical solution is not unique to each treatment function, but has a multiple effect on the system. This interaction of a technical solution to multiple treatment functions will play a part in the decision making process. Previous work by the authors has made a taxonomy of all technical solutions for the treatment function, and in this article, how technical solutions affect treatment functions is mapped. The article views the aquaculture production system as a transformation process with three sets of functions, input, treatment and output. Based on a comprehensive literature review where all technical solutions were found and categorized into a taxonomy, their effect on treatment function was mapped using a quality function deployment (QFD). The result is a matrix that gives an evaluation on the interaction. This work is a step towards an aquaculture engineering design methodology.

“…Reducing the bacterial load in the recirculating water by removing organic particles and bacteria by membrane filtration was previously described in marine RAS (Holan, Wold et al., ; Wold, Holan et al., ). A reduction in bacterial numbers can be achieved by removing organic particles from the water during the filtration process (Ray et al., ) or by the filtration itself.…”
