AB  - Reusing produced water (PW) as the subsequent hydraulic fracturing fluid is 
      currently the most economical and dominant practice in the shale oil and gas 
      industry. However, high Ca(2+) present in PW needs to be removed prior to reuse 
      to minimize the potential for well clogging and formation damage. In this study, 
      the microbially induced calcite precipitation (MICP), as an emerging 
      biomineralization technique mediated by ureolytic bacteria, was employed to 
      remove Ca(2+) and toxic contaminants from hypersaline PW for the first time. 
      Batch and continuous studies demonstrated the feasibility of MICP for Ca(2+) 
      removal from hypersaline PW under low urea and nutrient conditions. Throughout 
      the continuous biofiltration operation with biochar as the media, high removal 
      efficiencies of Ca(2+) (~96%), organic contaminants (~100%), and heavy metals 
      (~100% for As, Cd, Mn and Ni, 92.2% for Ba, 94.2% for Sr) were achieved when PW 
      co-treated with synthetic domestic wastewater (SDW) under the condition of 
      PW:SDW = 1:1 & urea 4 g/L. Metagenomic sequencing analysis showed that a stable 
      ureolytic bacterial consortium (containing Sporosarcina and Arthrobacter at the 
      genus level) was constructed in the continuous biofiltration system under 
      hypersaline conditions, which may play a crucial role during the 
      biomineralization process. Moreover, the combination of the MICP and ammonium 
      recovery could significantly reduce the acute toxicity of PW towards Vibrio 
      fischeri by 72%. This research provides a novel insight into the 
      biomineralization of Ca(2+) and heavy metals from hypersaline PW through the MICP 
      technique. Considering the low cost and excellent treatment performance, the 
      proposed process has the potential to be used for both hydraulic fracturing reuse 
      and desalination pretreatment on a large scale.
