Anodizing - Wikipedia

Anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.. The process is called ,anodizing, because the part to be treated forms the anode electrode of an electrolytic cell.,Anodizing, increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.

The pH of your ,treatment, system is a critical part of keeping your bugs happy. They require a near neutral (pH of 7) to slightly ,alkaline, (pH of 8) environment to thrive. If you have an ammonia limit, pH is even more critical because the nitrifiers consume alkalinity in the nitrification process, reducing the system’s ability to accommodate additional acid without impacting the pH.

In the pH scale, a value below 7 shows that a wastewater is acidic, a value of 7 is neutral, and values higher than 7 are alkaline. The pH values are logarithmic, meaning a pH of 6 is 10 times more acidic than a pH of 7. Biological treatment processes require neutral pH for the optimum growth of the treating biomass. 3.5 Why is pH regulated?

Acidic, is defined as having a pH of less than 7. The pH scale measures how ,acidic, or ,alkaline, (basic) a substance is. The scale is logarithmic and each pH value below 7 is ten times more ,acidic, than the next level. So, for example, a pH of 5 is ten times more ,acidic, than a pH of 6 and one hundred times more ,acidic, than a pH of 7.

1., Elementary pH, Adjustment: Just as alkaline wastewater has a higher tendency to foam, using elementary pH adjustment to lower the pH to neutral or slightly acidic often minimizes or eliminates the tendency to foam. 2. Antifoam: Using a high temperature antifoam or defoamer can be a simple and economical way to greatly reduce or eliminate foam.
