Nalco Water has water filtration specialists who are able to:
- Recommend when to use an autopsy procedure. Generally, we recommend the autopsy only when a detectable biofilm or fouling layer is present.
- Perform the autopsy. We look at current performance, dissect the membrane and check for damage caused by mechanical issues, fouling or chlorine.
- Provide clear results. In addition to the autopsy results, we provide recommendations to help you determine the best strategies for mitigating the membrane fouling problem.
The autopsy can include:
- Specialist selects the representative element(s)
- Dissection of a fouled membrane element to reveal the membrane leaves and plastic spacer material
- Chemical, microbiological and microscopic examination
- Crossflow test cells to characterize membrane performance
- Identification of the key foulants
- Documentation through photographs
- Remedies and recommendations
