Hello Discus Enthusiasts,
from my post in 'waste water reclaiming (http://forum.simplydiscus.com/showthread.php?t=74888)' i have been asked to explain a bit more detailed my system for water treatment, filtration and recycling, including RO as inline filtration with concentrate tank.
I want to start with basics about how my installation is setup in general, leading to the way i do automated waterchanges and RO Inline-Filtration.
My tanks are all in one row, build to hold a glas-on-glas installation as second row for future enhancements. Each tank has one overflow for 32mm pipes to run a gravity sump filter i developed by my self. Inside
the tanks a pipe in a T goes down and ends short above the bare bottom. With this installation i suck all waste into my filter. To supply water after filtration, each tank has one or two 20mm holes, depending on tanksize. All holes are drilled at the upper rim of the back.
My tanks are lit by 12V LED Stripes that are waterproof sealed in 10mm PVC Foam Lids to cover each tank completely. This not only helpes to reduce humidity in my fishroom significantly, but saves a lot of energy in the first place.
1. Biological Filtration and automated Waterchanges.
As mentioned before i use a central gravity filter for mechanical and biological filtration. My Filter has a prefilter chamber 1 wich is loaded with swimming beads and a 50mm overflow hole, connected to the wastewater drain. From chamber 1 to chamber 2 a 1.000µm Stainless Steel sieve. Chamber 2 to main filtration chamber can be covered with an optional 200µm Sieve.
Main biological filtration is done by up to 9 cartridges of 30ppm PUR Foam for in total max. 3.000l Water. This is my biggest filter, smallest is for 1.000 L. (see att. 3D Model)
Back to automated waterchanging:
in all gravity systems the mainpump of the filter supplies more water to the tanks than their overflow system can drain by gravitiy, until a balance is established and the system is stable.
In this stable condition i stop the mainpump by timer. With the mainpump standing, water still drains by gravity from the tanks into the filter, where water level rises and forces the filter to flow over into the drain. This way water leaves the system and part 1 of water changing process is performed.
During this process i switch on another pump, located in chamber 1 to set the beads in motion. The beads hold back a lot of waste from fishes, food and so on. As soon as they start moving, the dirt is released and sucked into the drain by overflow. The 1.000µ sieve is mechanically cleaned by the moving beads as well.
After 2 minutes i switch on the mainpump and off the Beadspump. With the mainpump working again, the filter water level falls by pumping water back into the tanks. The water removed by overflow is now refilled by a swimmervalve wich opens until water level rises again to its max. level.
Now, Part 2 of waterchange is done and my prefilter is clean.
The water quantity drained with each stop can be calculated. It depends on the surface of all tanks and the 'tide' between stable condition and lowest level before starting mainpump again. Total quantity per day depends on how many stops you programm with your timer.
The swimmervalve for refilling is located in the clearwater chamber. This chamber holds an additional overflow for RO Concentrate tank, but that's another story.
My next post will show some more pictures to illustrate how the whole system is working.
Now for today, have fun ;-)
