Afino conductividad - Development of a new salt water purification system in the tanning sector for reuse

The aim of the project was to develop a new wastewater treatment system for the tanning sector, based on membrane techniques, designed to lower the water salinity to levels suitable for re-use at an agricultural and industrial level. The chosen treatment was ultra-filtration (UF) of the water coming from the biological reactor, followed by reverse osmosis (RO). The rejections and purges from the whole process were dried out using thermal techniques (evaporator) and treated by an authorised administrator. Activities were undertaken in La Serrata leather tanning estate in Lorca, Murcia.
