An EC-20 system was installed to treat the waterborne effluent emanating from a dairy farming operation owned by a significant Māori Trust located in Kaitaia. This Trust is one of the most effective social service providers in the country facilitating the delivery of real and measurable improvements in the health, educational and housing outcomes of its people and credible reputation in environmental management.
Since around 2000 there has been an intensification on the New Zealand dairy cow farms. The number of dairy farms has declined over the past 20 years, however, over the same period the average herd size has increased from 251 to 419 cows, leading to higher stocking rates and being carried.
Furthermore, there has been an increased use of nitrogen fertiliser and a greater reliance on importing feed supplements such as maize silage and palm kernel expeller. As a result, on-farm structures such as feed pads or animal shelters/housing have been constructed by farms so that they can achieve better feed conversion efficiencies for this higher cost food.
This has resulted in cows being concentrated on these structures, with impervious surfaces (usually concrete), for longer periods generating greater amounts of effluent on current farms than compared to farms pre-2000. As such, on-farm effluent management has become much more complex as farmers are faced with having to treat different forms of effluent as either liquids, slurries or solids.
The most cost outcome effective solution for many of the challenges facing these farmers is the electrocoagulation system sources, design and installed by Maurilogical.
