Make Your Backwash More Effective With 4 Simple Steps
By optimizing your backwash system, you can improve your overall filter performance and reduce backwash frequency reducing media costs and excessive water usage.
- We recommend increasing your backwash frequency if you are experiencing:
- Excessive headloss (debris buildup in media)
- Diminished effluent water quality
- We encourage you to sample your backwash water on a monthly basis to detect system issues and ensure your system is working properly. We’ve included the four easy steps to sampling your backwash water below:
- Gather a sample of backwash water halfway through Simul-Wash™ or a backwash.
- Swirl the sample in a jar; if there is media present, this will cause it to settle in the bottom-center.
- Allow settling for a few minutes and note if there is media present. Any media collected should be minor – less than a dime in size and very fine in texture.
- If you see an excessive amount of filter media, your backwash water rates are probably too high. This will also affect your filter performance and shorten media life.
- Adjust the backwash flow rates to get highest rate without excessive media loss.
- If you haven’t checked flow rates recently (over the last 12 months), then using the above technique, gradually increase flow while sampling, until a trace of media is observed. Reduce this rate slightly to eliminate media loss.
- Simul-Wash™ and backwash durations vary depending on your raw water quality and frequency of backwash. Ensuring your filter media gets clean during backwash will improve overall filter performance.
If utilizing a Tonka Water, a U.S. Water Brand Simul-Wash™, backwash duration spans 6 to 10 minutes.
- Purge the air out of the media for about 2 minutes.
- Backwash until the water is translucent without any solids, about 1-5 minutes.
- Each system’s backwash duration will vary depending on your specific application and water conditions.
