Wastewater Question from the Field

Question: Can I “overwhelm” my wastewater system? Answer: Yes. When wastewater systems are overwhelmed, a pass-through event occurs. If more wastewater goes into the system than the system was designed to handle, the system is not going to be able to remove all the contaminants. The contaminants are going to go out the door. So, when introducing new processes in manufacturing, always consider ... Read More

Organic vs Acidic Paint Stripping Applications, Which Do You Choose?

Traditionally, paint stripping was conducted with methylene chloride or DCM, which is an excellent solvent that was prevalent across many industrial applications.

Organic paint strippers today are much safer and user-friendly. These products ha... Read More

The Importance of Bench Testing

Bench testing is not an exact science. Each test can produce slightly different results because every wastewater sample is slightly different. By using bench tests to help determine the best chemicals for the wastewater system, you can eliminate weeks of trial and error on a large scale. You will still need to adjust the wastewater system while the water flows to dial in chemical feeds, but bench ... Read More

Five Ways to Extend Bath Life according to our Metal Finishing Legend, Jason Potts.

Number 1: Before you put the bath in, passivate the tank and all the plumbing. Passivation is when you’re dissolving the nickel with a nitric acid, using a stainless tank in which you’re putting a passive film which stops it from plating out. A good nitric will stop it from plating out immediately. I’ve seen it happen many times. I’ll get the call and say, “Hey, I put... Read More
