  • Is a sustainable wastewater treatment system possible in Chile?
  • Each solution represent a possible design for a sustainable system of wastewater treatment plants in Chile. In addition, a best compromise solution from non-dominated Pareto front solution based on a fuzzy decision approach is proposed.
  • Is recycling wastewater reuse a problem in Chile?
  • According to MOP [ 79 ], in Chile, water, including recycling wastewater reuse, is a complex issue. There are more than forty governmental institutions involved in its management and the multiplicity of agencies and a lack of intersectoral coordination and collaboration is evident.
  • How is water reuse regulated in Chile?
  • (Modified from Vera et al. [ 32 ].). For water reuse, the practice in Chile has been to follow the guideline NCh 1333/87 [ 78 ]. However, NCh 1333/87 is a guideline focused on different water uses, including irrigation regardless of the source.
  • Why do refinery wastewater treatment systems need biotechnology?
  • In the traditional refinery wastewater treatment system, the biological treatment unit is critical to ensure that the effluent meets the sewage discharge requirements. When the wastewater is of low biodegradability (BOD 5 /COD<0.2), a single biotreatment process unit is generally not countable . Then, a combined biotechnology is needed.
