Talking about filtration. I'm using overflow filtration, so the surface would be always scum and debris free. It is just important to have clear surface in a pond, especialy when you have interesting things to see within.
Here is the planning. Water overflowing from the pond enters filter and go trough chambers of different filter materials. Then water will be collected at the end and pumped back to the pond.
1. Inlet from pond. Surface will be clean from film and any trash.
2. Filter chambers. Will be accordingly filled with brush, ceramic rings, bio balls, filter mat, sponge and filter floss.
3. Backwash drains (controled by individual valves)
4. Overflow drain, controlling water level at constant height.
5. Return line.
The filter is designed for ease of maintenance. Most dirt, debris, mud, whatever it is will be mainly stuck at the base of each chamber. The valves at the bottom of each chamber serves as backwashing system. Open the valve and the way will ease, draining the silt along. WC is also painless. Just open a valve to the pond, fresh water will mix evenly and end up at the filter as well. Water surface will rise over time and overflow at the filter drain, eliminating excess water. Heavy maintenance can also be done at spot with help of a hose. No need of moving around filter media and mess the house. Simple and easy.
I proposed a blueprint to my contractor and they did quite well as per requested. Here you can see the chambers taking shape.
