Washing down the yard to clean it of effluent makes about 25%* of a dairy farm’s fresh water use in a year. But what if this water could be treated and reused instead, without fear of contamination, risk to your reputation or the environment? The difference would amount to a potential total reduction in fresh water use on dairy farms of up to 42 billion litres per year (17,000 Olympic-sized swimming pools).

Developed in conjunction with our research partners Lincoln University, ClearTech® is an effluent treatment system that recycles water, and increases effluent storage capability. It also reduces the environmental and safety risks associated with farm dairy effluent.

FINANCIAL - INCREASES EFFLUENT POND STORAGE CAPABILITY

Pond storage availability allows more flexibility, meaning treated FDE can be strategically applied to meet optimum plant uptake and demand during ‘high risk, low demand’ periods.

ENVIRONMENTAL - SIGNIFICANTLY REDUCES LEACHING LOSSES OF TOTAL PHOSPHORUS, DISSOLVED REACTIVE PHOSPHATE AND E.COLI

In the treated FDE, ClearTech kills up to 91% of E.coli and reduces DRP concentrations by up to 99%. The coagulant used in the clarifying process ties up the phosphate, turning it into a slower release form of phosphorus. These reductions show that land application of treated FDE is less likely to cause adverse environmental impacts on water quality than spreading untreated FDE.

SAFETY - KILLS UP TO 99.9% OF MICROORGANISMS LIKE E.COLI

ClearTech significantly reduces the nutrient concentration in clarified water (CW), which means applying CW to land has less of an environmental impact on water quality than using untreated FDE. This offers more flexibility for use in both yard and irrigation situations, especially in the ‘high risk, low demand’ periods of August to November and when there is higher soil saturation in April / May.
