Profitable Sand Separation Management
Sustainable, clean and dry sandMavasol’s separator allows obtaining quality sand to be reused for cattle bedding, improving animal welfare and farm management.
This is the One Shot Sand Recovery System, a separator of organic waste, made by the American company Daritech and sold outside North America by the Dutch company Mavasol. It separates the sand from the solids to be used as bedding for cows. Future-proof innovation for Dairy farms. In cooperation with Daritech, we provide the most complete line of sand separation and process equipment in the industry. We strive to provide economical equipment with high efficiency and low maintenance. Sand is extremely suitable for use on large or small scale farms and we have SRS system to match your needs, the SRS system is designed for use in any environment. The SRS system is designed specifically for handling sand laden dairy manure The results we promise:

Here is how it works:
Slurry is scraped from the sheds into the first reception pit and is mixed vigorously with recycled water, creating a mixture that is then processed through the One Shot / Cannon auger. Clean sand is then deposited from the end of the auger chute. With the remaining mixture then going into a secondary separation lane with a 25cm auger bringing sand back into the auger shot pit. The mixture that goes beyond the secondary lane then goes through two more gradually sloping settlement lanes that allow further sand separation to take place.
After the series of settlement lanes, the mixture (which is now virtually sand-free) enters a further settling pit and is pumped into a separator that produces a sand free fibre. The remaining water flows into a lagoon from where it is pumped back into the system.
There are three elements obtained for three different uses: sand, which to ensure the best quality standards must have a size ranging between 0 and 2 mm, is reserved for cattle bedding; the dry matter is used in soil fertilization instead of chemical fertilizers, while the liquid fraction is conveyed into the tank to be used as a flushing, any surplus is placed in another storage tank.

Proven technology:
Daritech’s Sand Separation System is the one piece of equipment you need to lift, rinse, and stack quality reusable bedding sand! Combined with a cross auger for high capture, our patented dual flight design allows sand to lift and settle in the process of rotating up the tube of the One Shot. It operates with a broad range of sand sizing and is versatile enough to meet any specific dairy needs. Dual Flight Design: With flights attached to the inside wall of the tube, sand settles in the process of rotating to the top. Fiber floats in the water that slips through the upper split flights and cascades over the standard flights down the core of the tube, leaving the sand to exit the tube into a neat stack below. Once the fiber and water reach the lower double flight, it exits the tube. The slurry is quickly and easily separated. Two streams: slurry to the slurry silo, sand back to the sand boxes for the cows. |
Additional equipment:
We also offer a full line of GreenLine pumps to complement our Sand Recovery System, providing excellent value with heavy duty, high wear resistance for pumping recycled water and sand laden manure.
In addition, we provide process control systems to meet the varied needs of system designs.
All different components make that every system is tailor-made for your situation.

Sand separation benefits your enterprise...
Jensen: “First of all, less sand means drastically reducing wear and tear on machinery and pumps. This results in less cost in operation and maintainance.”
Gothard: “We are reducing the wear and tear on machinery and we have a dry and more manageble manure product that we can store effectively and spread more uniformly, cutting down our requirement for bought phosphate and potash.”
Bellomi adds: “Recycling your own bedding sand reduces the working time for the management of every single berth. If we consider that the use of straw as bedding represent an annual cost of € 70.000, in addition to a considerable amount of work and a series of management problems, the transition to sand has allowed to reduce the cost by 33%.”
Gothard: “The One Shot Sand Separation System separates slurry in thick and thin fraction. The thin fraction is excellent suitable for the slurry injector irrigation on the fields and the farm. It is easy to process because it is liquid, and you know the quality of what you are using. The nutrients are quickly available and that saves time as well."
Creating value for the green market.
Jensen: “I can deliver slurry to the future biogas installation of Grenå by separating the sand because not all the biogas installations are enthusiastic about raw slurry with a lot of sand in it. It builds up in their system and can get stuck in the tanks and pipes. With a capabilility of 95% clean sand recovery, these problems have been solved.”
Lassen: "We are ecologists, which is why there are fewer biogas companies you can go to. But with the dry, rich fiber fraction we have a product that might interest the biogas companies. As it is dry matter that gives the largest gas yield. Not water."
Improving animal health and welfare.
Bellomi: “The presence of flies and dust has been greatly reduced, I have recorded a reduction of decubitus lesions in the hocks and the dangerous slips of the cows that now, walking more safely, show better heat. That’s not all. The digital dermatitis (Mortellaro) has decreased by 50% and the same percentage accounts for the reduction of mastitis compared to the period in which I used straw for the bedding; the somatic cell count has decreased and the use of disinfectants has also been reduced.” Gothard saw significant benefits of sand bedding straight away. “Cows are clearly more comfortable in the new beds and spend more time on lying down. And the improved grip on the concrete means fewer slipping incidents. Cow cleanliness, udder health and milk hygiene have also improved. Happier cows are generally more productive.” |
Integration of a new Sand Recovery System into the farm’s slurry management, is a key step towards a progressive and sustainable dairy.
Gothard: “We have a dry and more manageable manure product that we can store effectively and spread more uniformly, cutting down our requirement for bought phosphate and potash. It's about future proofing our business. We've secured our use of what we see as the best bedding system for cow health and welfare, through recycling a finite resource, reduced our requirement for fresh water and cut our reliance on bought-in fertilizers. Of course it's important for our business to be viable, but it's also a good message for consumers to now that farms are investing in sustainability for the wider benefits this brings. “ Lassen: “I have invested two million Danish crowns in a sand washing plant. The money is going to be earned by reusing sand for bedding and expected delivering the dry fraction to biogas plants.” Bellomi: “With One Shot Sand Recovery System, I think we can really talk about a global approach to the concept of circular economy that today is a cornerstone of our business. Everything that the farm produces, in fact, is reused without waste. All in the name of environmental sustainability and with significant savings in time and money. The efficiency of the plant allows you to recover 95% of the sand separated from the solids. This seems to me to be a figure that speaks for itself and that, together with all the other aspects listed, demonstrates the validity of this choice.” |
Circular economy: investing in efficiency and recycling.
Last but not least, the Sand Recovery System helps the famers to tying the end of the chain to the start of the same chain. The circular economy is receiving increasing attention. Waste is becoming increasingly taboo. More and more citizens, governments and farmers are aware that we must change our linear economy into a circular economy. The circular economy is also about fewer and smarter raw materials, sustainable energy, preservation of culture and biodiversity and well-being. The Dutch agricultural sector is a global leader in circular agriculture. Mavasol is very proud to announce that several projects have received support of Dutch provinces and the European Agricultural Fund for Rural Development. This makes it clear that Mavasol helps farms with the transition to a circular economy. |
