Pre-treatment for RO process at an aerospace multinational in Hungary
NX Filtration delivered its nanofiltration membranes for industrial wastewater treatment at the site of an aerospace multinational located in Hungary.
The customers query
The customer, an aerospace multinational located in Hungary, was looking for a pre-treatment solution for its reverse osmosis (RO) process of wastewater streams from the cleaning of airplane engine parts.
Our approach
We applied our dNF40 nanofiltration membranes after a complex wastewater treatment process to decrease the cleaning frequency of the RO system and increase the lifetime of the reverse osmosis elements.
The result
The dNF unit combines 200mm and 110mm dNF40 modules in a Christmas tree arrangement with partial recirculation to increase the overall recovery. We realized a reduction of the RO cleaning frequency as well as a prolonged lifetime of the RO elements.
