  • Why is salinity important in wastewater treatment?
  • Salinity is an important parameter for wastewater treatment (Kartal et al. 2006). Wastewater is defined as “high-salinity” or brine when the inorganic salt contents range from 1 to 3.5% w/w, and seawater usually contains 3.5% w/w sodium chloride (Pernetti and Di Palma 2005).
  • Does high salinity affect biological wastewater treatment?
  • Although high salinity may inhibit the effectiveness of aerobic and anaerobic biological wastewater treatment methods, such strategies as selecting salt-adapted microorganisms capable of degrading pollutants with tolerance to high salinity and optimizing operating conditions can be effective.
  • How does high salinity of wastewater affect microbial communities?
  • However, high salinity of wastewater leads to osmotic pressure in microbial cells to exceed normal living conditions, and a massive die-off can change the sludge microbial communities (Pollice et al. 2010; Zhang et al. 2019b), which considerably reduces treatment efficiency and limits traditional biological treatment technologies.
  • Can high salinity wastewater be treated?
  • However, the discharge of untreated high-salinity wastewater may cause serious environmental pollution and affect the aquatic life, water potability, and agriculture (Lefebvre and Moletta 2006). Therefore, it is necessary to use various methods and technologies to treat high salinity wastewater.
