Fish canning industry wastewater treatment for water reuse - a case study

As regards the energy and chemicals costs, to obtain a treated effluent to be reused in the process costs 0.85 €/m3. This value can be reduced by about 60% if the goal is only to meet the legislated standards for the effluent discharge into water bodies. Tap water for the industrial plant costs about 2.1 €/m3.
