Thread: My farm used for final project

^ Ha ha ha ha ha.....I wish mate, but sadly no, it from our own means...

Interesting stuff Dalton, beats my 900 l. aquarium a million times.

^what do they taste like?

yes, I thought about your operation for hours on end when we met last.
I never once thought to ask the obvious question. Are they they the same tasteless products that shrimpfarms around the Kingdon claim to be the global answer? The shrimp are quite tasteless. I wonder if your product is superior...

Ask BosseO about that... But looking at them, there aint to much meat...

Can't afford to eat them, you probably have to ask the natives around the Amazon river about the taste.

The water is in motion all the time, and so is the fish, that makes it more firm and healthy. We are in control of the water-parameters, so we can provide the best quality for the fish, compared to cage-farming who are stuck with the water there are in the river.

Dolton it have been a long time since the last up date on the farm.
Sorry I have been busy with work soon I will see about the butterfly valve from China for you.

^ Point taken, been busy goofing around doing some research with Pengassius and Sea-Bass.
So far the test from the uni is going fine, there results are positive, however they still dont quite understand how the system works, but they're getting there slowly.

This is the trickle bio-filter for the first 17 tanks, total water volume 176m3 for that system.

Dalon your bio filter are very large, the 176m3 is the flow rate 24 hours.
Have you look at a bio uplift filters
To me the bio uplift is more simple ( I don't know much about water treatment for fish farming) only swimming pool & house hold water.
I have been asking my Engineers to do some research on the bio uplift filter.
But like every thing in Thailand tomorrow & tomorrow never comes.
Maybe one day the will finish the job.

^ In this system the 176m3 circulate through the bio-filters every 4 hours, so the total of 1.056m3 per day. The other system we have does it every 2 hours, total 2.112m3 per day. We change roughly 10% of the water per day.

everybody has their own favoured system. if you are talking UPFLOW i would say that the trickle tower is far superior, since the bacteria are exposed to highly oxygenated water, allowing for a far bigger colony of bacteria to be supported.
remember, too, that the bacteria needed for the conversion of nitrites to nitrates are AEROBIC, and oxygen is the key to the whole equation.
if you were talking about an AIRLIFT system, of course the problem is eliminated.

Your trickle bio-filter is simply amazing! I'm jealous!

^ Dont be mate, build a small system to try it out, aint that expensive..

Here are a picture of some tanks in operation.

Might be a stupid question but...
What does the water get filered through, do you have different layers of filtration, how often do you change or renew filters or layers?

Dalton this is the type of filter I will look at when the Engineer get of there Dootttt & do some research diametre X Height, water flowrate & air flowrate required.
Many company manufature a simple count-current protein foam fractctionator.
At a price $$$$$$$$$$, but the cost are not that high to manufacturte.
I have been manufacturing swimming pool filter in Thailand for 2 years now trying to sell to the Thai swimming pool builders.
No they are not interested, a very large American company come to make a deal with us & the American company sells to the Thai pool builder ?
I can not work out the logic it.

good luck.

OK the sludge is removed by sand filter the same pump is used for the airlift filter.
The amount of air is only small ( so I have been told) I think that the media is inside the tank, not sure.
I manufacture sand filters, I like to look at Bio filter, I would like to build a test unit & see . As all the ones on the market are expensive

What you have there is what we call a protein-skimmer, the air-bubbles are used to remove particles less than 10-40 micron, the particles will be caught by the bubbles and brought up to the surface where they will turn into a white/brown form there will come out on the over-flow on the top of the tank.
Those skimmers we build ourself, they are to expensive to buy, for normal people..

The water first get to a drum-filter, there remove all solids over 50 micron, then you can run it through protein-skimmers like Ratchaburi have posted, then it runs to your bio-filter, it removes the nitrite and ammonia there are toxid to the fish.

I am reading this and while it is way out of my league to consider I find it a fascinating thread. Dalton please keep us posted on your progress. I for one would be very interested to read more and especially how it could be adapted on a smaller scale for home based sufficiency with some limited stock for sale. Quite a few years ago I read up a lot about permaculture and became very interested in it.
