What is Acidic Wastewater?
Many common wastewaters are considered acidic. Acidic is defined as having a pH of less than 7. The pH scale measures how acidic or alkaline (basic) a substance is.
What are the Concerns with Acidic Wastewater?
A pH below 2 is considered corrosive and is classified as hazardous. Even acidic wastewaters above 2 can be a concern due to its potential to prematurely corrode metals and other materials.
In industrial wastewater evaporation, the pH, temperature, and inorganic chloride levels have the greatest impact on potential material corrosion.
Using our SCTCRISTS for Acidic Wastewaters
SCTCRISTS .uses 316ss as the standard material of construction on all wetted parts in our evaporators and combustion furnace. This durable stainless steel is appropriate for most applications, but if the combination of wastewater pH and level of inorganic chlorides is determined to be too corrosive, SCTCRISTS offers a number of solutions.
1. Often the simplest solutions is to do an elementary pH adjustment to bring the waste stream to a pH between 6-7. This solution is generally affordable and can be automated. If your waste stream is deemed hazardous due to the low pH, adjusting makes even more sense
2. Another option is using a more corrosion resistant alloy of construction for the tank and heat exchanger.
If our SCTCRISTS is right for you
The centerpiece of our consultative approach is the wastewater qualification process. Not all waste streams are good candidates for evaporation. We believe it’s better to find that out in our laboratory than on your factory floor.

This free analysis determines how appropriate the waste stream is for evaporation and how it will function in our SCTCRISTS. This analysis also helps determine materials of construction and allows us to determine operating procedure recommendations. If more detailed analysis of specific parameters is needed, SCTCRISTS can prepare appropriate samples and send them for outside lab analysis for a nominal cost (prices for analytical tests vary).

Once the analysis is complete, your SCTCRISTS Sales Engineer will deliver a report detailing the results to you. This report includes material of construction and pH adjustment recommendations, if needed. This allows you to make an informed decision if our SCTCRISTS is right for you.
