Tony Franken's Dairy.
Comboyne, N.S.W
The contribution of Tony's dairy effluent treatment
plant at Camboyne has made a large reduction in effluent turn around
time and 1000ltrs per day is used to hose out the dairy after
milking. Rank weed growth and smelly muck soaked areas at the back
of his dairy was the norm. Not now though. Tony is able to use this
valuable resource to irrigate his farm. Recycling the water and
applying the manure waste to his irrigation equipment has many
benefits. Traditional dairy effluent processing which relies on
anaerobic decomposition can take up to four months, then the
question arises, "What to do with the mess?"
Tony's plant relies on aerobic decomposition
(flowform and Bio Dynamic Manure Concentrate) and produces a ready
to spray liquid in one week. By slightly opening the sprinkler jets
the whole liquid is sprayed onto the paddock. The cows then
immediately graze on this grass. An unheard of scenario using
traditional methods.
The plant comprises of 2 x 9000ltr concrete site
cast tanks with 14 Jarna flowforms and phi ratio spoon. The spoon
enables the water to be directed to either left or right hand tanks
Between the tanks is a triangular pump chamber and by opening or
closing the valves, either left or right tanks are aerated. Tony
runs the 14 flowforms at night which enables the introduction of
more oxygen.
One of the tanks is filled from the shed via a sump
and coarse strainer. When full, the 14 Jarnas are activated and left
to run for 5-6 nights as the other tank fills. Once sufficiently
processed the first tank is used for irrigation whilst the second
one fills. The Bio Dynamic Manure Concentrate is used in the tank to
expedite the aerobic decomposition and is available from the BDFGA
Association for $30 per kilogram or made very cheaply on the
farm.
Tony is quite pleased with his plant and is enjoying
the benefits brought to his herd of cows. Another great use of
Flowforms.
