Slurry Channel
What is a Slurry Channel?
A Slurry Channel is a gravity flow system used to transfer dairy manure in liquid manure handling systems. The correct installation and management of slurry channels is essential to their operation; but as long as the channel is carefully designed and care is taken with the foundation and the correct management schedule is followed, then an incident free operation should be achievable.
Advantages of Slurry Channels
• Reduces or eliminates the need for mechanical manure handling systems for transfer of manure from the barn to the storage area.
• Straight forward design and general operation.
• Good reliability.
• No agitation of manure is required inside the barn.
Disadvantages of Slurry Channels
• Use of sand bedding is not possible in a gravity system.
• Manure which has become frozen, is dry, or contains an excess of long hay, straw, or sawdust bedding will not flow in a gravity system.
• The design must enable the manure storage or reception pit to be lower than the barn.
Slurry Channel Design
The consistency of manure will vary depending on the type of feed, the class of animal, bedding type and the amount to which the manure is frozen or dried. When a slurry channel is being designed it is essential that all of the above factors are taken into consideration and that it is designed to accommodate a wide range of manure consistencies. This will ensure that the channel will continue to operate regardless of changes in the manure consistency, time of year, or type of feed used.
There are several ways of constructing a slurry channel ranging from; precast sections to insitu concrete channels, or a combination of the two.
Concrete slurry channel Sections
Probably the simplest and fastest method of creating a slurry channel is by installing prescast concrete slurry channel sections on-top of a concrete foundation slabs. These units are quick to install and easy to seal to provide a watertight seal. In addition to the channel sections, precast lids are also available including; diagonal cattle slatted, diagonal tractor slatted and solid dust covers.
Precast + Insitu Slurry Channel
Another option is to use precast concrete wall panels to create the vertical side walls for the slurry channel and the pour an insitu slab to form the bottom of the channel.
Insitu Slurry Channel
A slow and expensive way of creating channels but allows for flexibility of dimensions.
