• Reuse of the wastewater can be optimised by using the MINLP coordinates technique.
• This technique can be expanded regarding the usages of wastewater for utilities and raw materials.
• Distribution from the main reservoir could be used for the parallel or sequentially split parts.
• The parallel or sequential split parts including different alternatives for usages of wastewater.
Natural resources are limited, so we need to handle them carefully. Wastewater also belongs as a significant natural resource. The re-usage of wastewater is to save fresh water and for the preparation of raw materials or/and utilities. The wastewater re-usage distribution can be optimised using mixed-integer nonlinear programming (MINLP), as a tool in combinations using the coordinates technique. The main goal of this MINLP coordinates technique was: i) wastewater and condensate, as produced during different industrial processes, could be collected for: utilities for steam-generation, and the preparations of raw materials; ii) wastewater and condensate could be collected within the main reservoir; iii) distributions from the main reservoir could be used with including different alternatives, which can reduce pollution, based on the re-usage of wastewater. Alternatives included in the optimization model represent potential solutions, which need to be evaluated on appropriate way.The MINLP coordinates technique for wastewater re-usage distribution was tested on existing formalin and methanol industrial processes, thus allowing the saving of water and generated by 280 kEUR/a profit.
