Provided is a novel Nanofiltration-DiaNanofiltration (NF-DiaNF) system and method for extracting divalent ions from saline water (e.g., seawater) to produce solutions rich in divalent ions (in particular Mg2+, Ca2+ and SO42&#x2212;), while minimizing the concentrations of undesirable species (e.g., Cl&#x2212;, Br&#x2212;, B and Na+). The solutions may be added to water (e.g., desalinated, soft, drinking or irrigation water) to enrich the water with divalent ions, thereby improving its quality.

Method for separation of magnesium and calcium ions from saline water, for improving the quality of soft and desalinated waters

Provided are physico-chemical processes for continuous and simultaneous water disinfection, oxidation of off flavor agents, minimization of trihalomethane (THM) production, reduction of nitrate and nitrite production and oxidation of ammonia so as to remove nitrogen species, in saline (for example, seawater) based aquaculture systems. The aquaculture system may be any handling/storage/transport system, for example, recirculated aquaculture systems (RAS), for fish or other aquaculture species.
