K1 static bed filter

[aswin785]

Hi all , I ve recently made a static k1 filter for my pond, using drain at the bottom of the tank is used for draining the water from filter, instead of that can I make a bypass valve at outlet to wash the filter by continuosly running the air until the water runs clear, will it take more water than bottom draining method...?

Use drain full open first with no air to remove debris at bottom layer. Usually just a short blast is needed. Close and then turn on air to clean K1. Let it boil for awhile and when you feel dirt has dislodged from the K1 start flushing .

This is what I'm trying

I am in the very slow process of building something similar but I plan to have my two upflow static filter containers in parallel, each with their own separate drain to waste. I will be using 2m tall filter containers with small viewing windows.

To clean, I will be diverting all water flow through one filter (so water pump never needs to be turned off/on), the isolated filter will be air stirred to dislodge trapped dirt, then allowed a few minutes to settle before being drained. I don't expect to get the filter totally clean but the cleaning process will be easy and could be automated if this proves satisfactory.

If your looking for feedback on your design, I dislike the idea of the first filter waste having to go through the second filter and then the sump to escape. However you may have your own reasons for doing so. You could improve the efficiency and reduce water wastage by diverting the water pump back through the first filter during the clean cycle if you allow a settle out period- so recirculating water through the filters and sumps only but you wouldn't get them totally clean.

If water waste is not a concern then your idea should work.
