Slurry Separator for Prosiectslyri Project

T-T Agricultural and Environmental® recently supplied a Cri-Man slurry separator to Coleg Sir Gâr’s Gelli Aur Farm, a 211-hectare, 500-cow college-based farm that facilitates agricultural study and research.

The SM260 slurry separator was supplied as part of the Prosiectslyri Project, a £1.1M project funded by the Welsh Government through the rural development plan to address the agricultural industry’s environmental impact.

Prosiectslyri Project

The Prosiectslyri Project will see Coleg Sir Gâr’s Gelli Aur Farm and Power and Water, a Swansea-based water treatment company, working together for three years to develop a new kind of purification pump system for managing farm slurry.

The system works by pumping raw slurry into one of two mechanical separators which removes the liquid fraction, resulting in solid material a 10th of the slurry’s original volume (Farmers Weekly). The separated solids are dropped below and stored for later use as an arable field fertiliser, full of naturally occurring vital nutrients.

The liquid portion of the slurry moves on in the treatment process, where a system of oxidation breaks down ammonia into nitrogen and hydrogen and removes any remaining solids, adding them to the separated solids from the beginning of the process.

Two separators are being trialled in an effort to deliver the most optimal separation results, they are a screw press filter and a decanting centrifuge that uses centrifugal force to separate solid and liquid materials. The SM260 Mini screw press separator supplied by our agricultural experts is constructed in cast iron with components manufactured in stainless steel and has a rotary, double-threaded screw in a longitudinal slit filter that can produce up to 30% dry matter.

Environmental and Cost-Saving Benefits

Success of The Prosiectslyri Project will bring about benefits for farmers and the environment alike.

Slurry storage and transferal bring the risk of pollution should a leak occur, as the run-off can enter and contaminate nearby waterways. This new system of slurry purification mitigates this risk by separating the solid and liquid fractions and purifying the resulting liquid content for safe reentry into our watercourses or for use around the far.

In addition to reducing water usage, the separated solid portion of the slurry that remains packed with helpful nutrients is valuable as fertiliser, bringing further cost savings by allowing cattle farms to utilise a readily available asset; slurry.

For Coleg Sir Gâr’s Gelli Aur Farm and their 500-strong herd, this could result in annual savings of £16,908 on bagged fertiliser due to the higher nutrient content of compressed slurry (Farming Connect).

How it’s Going

According to Farming UK, the equipment is exceeding expectations and extracting 90% of liquid from the slurry, 10% higher than what was anticipated initially.

Ben Nash, sales director at T-T, comments: “We are grateful to have the opportunity to be part of such an innovative project. It’s early days in the project but this is huge for the Agricultural industry and a step in the right direction. We can’t wait to see the results of this over the next two years and see it employed in farms across the country.”

Lesley Griffith, technical officer at the Prosiectslyri Project, comments: “In all of our dealings with T-T Agricultural and Environmental, Prosiectslyri Project have found them to be very efficient and supportive at all times. We would gladly recommend their products and services to others.”
