This has for us often been a compromise with flow through construction. Have had some success with this at numbers in 10 kbm against gravity feed (1.3-1 m) to waist and ½” full bore. Ball valves with v-cone are an excellent choice if you would like the opportunity to fin tunes your system. We simply love the 75mm and can easy live with the 50 mm.

Generally this makes for a superb setup the only downside is running cost. All considerations off build-up of any kind are all gone.



At our setups we use overflow to waste and electrical valves for purge and refilling all over a normal block timer. The power to filling is routed through a delay timer. After power through the timer cuts and closes the flushing we have an adjustable time left for filling. With a little fine-tuning it’s easy to get it right in our indoor system just by keeping a tab on temperature, level in system an overflow. We use a 75mm ball valve for flushing and have opted on frequent ratter than constantly. (Just a mater off cost)



Bill when we mentioned power consumption and footprint we where pointing to units easy mounted on a wall. I can lift one (don’t tease now) for 50 tons per hour and the footprint would bee ~450x200x500 with flanges. To get these to function we have had problems without controlled inlet pressure witch mean pressure pumps and valve. Function is as always in regard to price. Her in Norway it’s really high and we have not use this “trough vortex” on any ponds. Its far more normal on process water to chemical plant and so on.
