Auto Body Shop in North Carolina Uses i2m CERA~DUR Filtration Technology to Meet Water Reuse Requirements
One of the largest auto body shops in North Carolina needed a wastewater treatment system prior to their opening in Boone, NC. Due to no POTW access and onsite disposal restrictions, the wastewater needed to be treated in a closed loop system in order for the water to be reused. It was critical for the auto body shop to find a solution quickly as they could not open without a wastewater treatment system in place
Efficiently reduce and reuse wastewater and meet discharge limits.
The auto body shop is located just outside the city limit, so the shop does not have access to the city’s sewers or discharge facility. Time was critical as they could not open without a wastewater treatment system.
Technology and Operating Conditions
Product: 2 CERA~DUR 6 Series Modules

- <1 (ppm)
- 45 (mg)
In conjunction with one of our partners, a two-phase system was installed. The first phase is an ozonation system which chemically degrades organics and in organics. The second phase requires an ultrafiltration system using i2m’s ceramic hollow fiber membrane, CERA~DUR.
IOT sensors used to monitor the membranes’ performance remotely, and optimize cleaning cycles.
With i2m’s innovative CERA~DUR ultrafiltration (UF) technology, the auto body shop was able to recycle and reuse nearly all of their wastewater.
The system is successfully meeting the reuse quality requirements with 100% retention of suspended solids and a permeate water containing less than 3 ppm of oil and grease.
The sensors significantly support the system integrator to optimize the membrane performance remotely and reduce downtime and cleaning costs.
The system has been running since November 2016 and is successfully meeting all the reuse quality requirements with no membrane replacements to date.
