Dairy Liquid Effluents Treatment
Ready for a New Concept?
No more time and ressources wasted on managing dairy effluents. No more potential health and pollution hazards. And that is just the beginning.
Only a fraction of GHG and ammonia emitted in the air
Separated water can be re-used
Depending on the needs, separated waters can be made rich or poor in nitrogen. And used for crops or released in the sewage.
No more transportation costs
All effluent, including separated water, is treated locally, with no pollution.
Fast and Cheap Separation of solids and water from liquide manure
Historically, the high-volume, high-water content of liquid manure has been a burden for dairy cows and hog farmers. Difficult to store and to transport, its inherent value is small when compared to the risks it brings. In terms of health hasards or pollution.
Agriwaters process is unique. It allows an easy separation of liquid manure into a solid and a liquid phase.
The Waters
This one-step separation leaves a watery phase rich in nitrogen, but with no other minerals or germs. It can be used for crops. In the winter, a second step can be applied to release the nitrogen and allow a simple discharge of water to the sewage. Hence simplifying greatly the work of farmers.
The Solids
The solid phase can be applied on crop fields. It is rich in phosphore, nitrogen and other key-minerals. Trapped in a stable organic matrix, these nutrients are slowly released when applied on the fields. The organic matter has a high Cation Exchange Capacity, helps structure the soil, and is a ultimately a food source for many organisms that live in it.
Agricleantech for a Low Environmental Footprint
FAQ
Is this technology expensive to install?
The short answer is: no. We do not re-invent technologies that already exist. Here the novelty are modules that can be integrated in a system made of components that many farms already possess partially.
Agriwaters technology allows a cheap separation of manure effluents into a solid part and relatively clean water part. Why do we need that?
Huge volumes of liquid manure, generally not well defined in its composition, are produced by cow and pork farming. Although it can be a good fertilizer, the reality is that there an excess of such a fertilizer on the market. Moreover, it is expensive to store and to transport. It is also instable and loses its nitrogen to the air over time. Manure is a major source of water pollution. Our innovation is allow a cheap separation of manure into water and a small-volume, dry and stable fertilizer.
What do you mean when you say that manure is stabilized?
Manure without bacteria and fungi does not produce gazes, hence does not lose nitrogen. Manure is a complex mixture of organic compounds that are used by microorganisms for their growth. Urea in liquid manure is transformed to ammonia. Ammonia evaporates, leading to a loss of nitrogen. Other compounds produced are N2O (hilarous gaz) or methane (CH4). These two compounds are very strong greenhouse gazes (GHG).
What is done with the separated waters?
In winter, or in other circumstances, the water is clean enough to be sent to the sewage. Remember that liquid manure cannot be sent to the sewage!
In a time of the year when crops are grown, the water can be used to sprinkle the fields. In this case, the nitrogen can be kept in order to add fertilizer to the crop!
Is manure really a health hazard?
Manure is dangerous. When stored, ammonia and hydrogen sulfide are produced: these gazes can hurt humans by inhalation. If a worker falls in a manure pit, he might be killed by breathing gazes. It happens regularly, unfortunately. Pathogens present in manure can enter the lungs, when an aerosol of pathogens is produced, by the wind. This might also affect the health of workers.
