The purpose of the project was to replace a metal container by three plastic containers storing Sodium Hydroxide (NaOH). The NaOH was used in this case as a pH control agent in a wastewater treatment application. Apart from this, the concentration of the solution was increased from an initial 20% to a 50%, in order to reduce costs during the future treatment process.
