  • What is the impact factor of industrial waste treatment (IWTP)?
  • Based on the described modelling approach from all Dutch 182 IWTP, that cover 43 different industrial (sub-)classes, only a limited number at low discharge or at high discharge have an impact factor higher than 0.1% ( Table 4 ). These IWTP are typically related to the plastic, paper, petroleum or basic chemicals industry (see also S.I.B.2.).
  • How much industrial waste water is treated by STP?
  • The volume of industrial waste water treated via STP, equalling 7.9 million inhabitant equivalents, is in the same range as industrial waste water directly treated via Dutch IWTP equalling 13.8 million inhabitant equivalents (data by CBS Statline, 2017 and personal communication Kees Baas Central Bureau for Statistics).
  • What percentage of STP effluent comes from household and industrial waste water?
  • Most STP effluents result from mixed input by households and industrial waste water, e.g. 93% of Dutch STP treat mixed household and industrial waste water and the proportion of industrial influent is on average 24% with a maximum of 90% (personal communication Kees Baas Central Bureau for Statistics).
