This article is a comprehensive review of the literature dealing with the transfer of carbon dioxide to water where no chemical reactions are taking place. It reviews the studies related to the absorption and desorption kinetics, mass-transfer rates, effect of the contactor geometry, effect of water salinity, and the effects of temperature and pressure on the process in conventional reactors or the more recently common membrane contactors. The available data show inconsistent trends and an abundance of system-and geometry-specific correlations/models to predict the mass-transfer performance, which may explain the inefficient design of most industrially available contactors. Furthermore, no agreement can be found in the literature on the effect of temperature and pressure of the system, as well as the presence of additives in the water, on the solubility of CO 2 .

“…Additionally, the injection of micron‐sized air bubbles into a foam fractionator increases aeration and CO 2 removal (Barrut et al., 2013). For example, an airlift pump with CO 2 ‐stripping can remove 13‐20 g CO 2 kWh −1 (Loyless & Malone, 1998) and paddlewheels 1.2 kg CO 2 kWh −1 (Eshchar et al., 2003).…”

Good water quality in recirculating aquaculture systems (RAS) is crucial for ensuring the successful growth and survival of reared species. So far, there are no regulations for which parameters should be measured in RAS, and each farmer decides which parameters to follow. Traditionally, water quality parameters have been measured at certain intervals with handheld sensors and laboratory analyses, which can be labour intensive. Currently, a variety of sensors and monitoring equipment is available, even for the real-time monitoring of water quality parameters. Internet of Things-based systems and artificial intelligence can be applied for the monitoring purposes which allows real-time measurements and warnings of critical situations. However, many of the modern systems need competent users and require regular maintenance and calibration. Changes in water quality also induces changes in fish behaviour, such as swimming activity, depth, acceleration and water quality can be assessed also based on these changes. In this review, water quality parameters, variety of sensors and monitoring technologies have been summarised to provide an overview of the current monitoring systems for water quality. Additionally, analytical methods for more advanced analyses have also been briefly summarised. Although there are several advanced options available for monitoring the basic water quality parameters, real-time measurements of more advanced parameters still required require further development.

RAS utilises modern knowledge of biology, environmental sciences, mechanical engineering and information technology (Xiao et al., 2019). Circulating water is reused multiple times, and only a small proportion is replaced with clean water (Chun et al.
