Separation of cattle manure

Due to lack of straw, a dairy farmer was looking for an alternative bedding material for the cubicles of his 240 dairy cows. For economic reasons he opted against expensive sawdust and for a separator.

He installed a Bioselect RC 40 separator with Börger control technology and a BLUEline rotary lobe pump. The control unit coordinates the operation of the feed pump, the liquid phase pump and the separator perfectly. Automatic separation at required times can also be selected.

The DS content in the solid phase can be continuously adjusted with ease. Thus, the farmer selects a high DS content (>30 %) for use as bedding material and a low DS content (approx. 22 %) when the solid phase is to be delivered to an associated biogas plant, saving storage capacity of up to 25 %.

Using the separated solid phase as bedding material works very well. The cows like to lie on the soft material and the bacteria count in the milk continues to be at a very low level. The customer is very satisfied with his Bioselect.
