Industrial treatment troubleshooting
DNA can help you
By Trevor Ghylin and Steve Leach
Industrial wastewater facilities tend to treat wastes with highly variable flows and concentrations. As a result, these facilities tend to be difficult to operate and may have issues with settling, toxicity, and ammonia removal. Operators struggle to understand operational issues resulting from a lack of information on the bacteria responsible for these processes. Troubleshooting issues may consist of microscopy as well as checking pH, alkalinity, mixed liquor suspended solids (MLSS) and a lot of head scratching.
Fortunately new DNA technology enables users to see what is going on with the bacteria directly, rather than looking only at indicators and surrogate measurements. DNA technology finally can answer the most basic question: do I have the right bacteria growing?
