Reverse osmosis is a popular choice for water treatment in automotive manufacturing. Here are 3 ways reverse osmosis helps automotive manufacturing:
Consistent Water Quality
By installing a reverse osmosis system, auto manufacturers can count on the same, consistent permeate day in and day out. If you install a Closed Circuit Reverse Osmosis (CCRO) system you can even feed the system variable feed water and the system will automatically adapt while delivering the same quality permeate required.
Depending on initial water chemistry of the feed water, an automotive manufacturer can generally expect between 75% and 95% recovery. Adding pretreatment can help to increase this recovery and choosing a reverse osmosis system provider that can guarantee recovery is also very important. If you get a quote that is lower than 90% recovery, you may want to look into alternative reverse osmosis processes (such as CCRO) to see if you can save any additional water. Generally traditional forms of reverse osmosis struggle with higher recovery rates and require a lot of pretreatment to match recovery rates of newer forms of reverse osmosis such as CCRO.
Low Operating Cost
Unlike other water treatment processes that require costly maintenance (think regeneration of Ion Exchange), reverse osmosis generally requires a Clean-In-Place treatment every few months. Of course, the frequency will always does depend on the feed water chemistry, so when reviewing proposals for a new reverse osmosis system or a replacement reverse osmosis system, it’s important to ask the provider about fouling and scaling potential. Certain reverse osmosis processes actually resist fouling and scaling more than others, which can lengthen time in between cleanings savings costs and down time.
