Slow sand filters are cleaned by taking them off line and draining them. The organic or contaminant layer is then scraped off. The filter can then be restarted.
If you want a greater service flow rate, the best solution is to install two 10" filters side by side. This gives you a healthy and effective gallon service rate. You set the timers on the filters so that they backwash at different times, then you have an adequate backwash potential of six gallons for each filter.
