Why does a given community stipulate that backwashed DE goes to a separation tank and not to their sewers? Can I just waste the backwashed DE onto my property? Isn't DE biodegradable?
That would be a great question to ask community leaders. DE or Diatomaceous Earth is already present in the ground, isn't toxic, or harmful to small animals. So I have no idea why that stipulation exists in your community. I would assume false or misinformation is what led to this being addressed from a disgruntled neighbor.
I use cellulose DE replacement, which is biodegradable, and I backwash onto my lawn.
Yes, you need to clean the filter out thoroughly. And the cellulose is really light and fluffy, so a huge bag weighs hardly anything. Volume-wise, they're probably close to the same amount to coat the screens. And I will tell you from personal experience, it filters really good, and when it hits 25% increase, you need to backwash now. Once it goes up 25%, it seems like it only takes a week to go up to 50%, and you will actually notice a decrease in flow.That's crazy. Just looked that stuff up. I use 7.5 LBS of DE. For my filter they say only 36 oz. switching probably requires a disassembly of filter to get all old de out though I bet.
I use fiberclear, or whatever brand it is they sell at the local pool store.Do you use the same stuff Richard? I
I'm not sure the link provided indicates "moderate" quantities.....it looked more to me like VERY high quantities. What are moderate quantities?DE is heat treated which transforms it into crystalline silica which causes silicosis and cancer when inhaled in moderate quantities
