Ramping up slurry tank capacity
A range of mobile holding tanks to aid with the spreading of digestate from biogas and anaerobic digestion plants has been launched by Northern Ireland-based firm SlurryKat.
Responding to increased demand in the Nordic countries, the engineering division at SlurryKat, based in Waringstown, Co Armagh, designed and built the mobile nurse tank which acts as the master tank when spreading digestate with an umbilical slurry system.
Biogas plant operators and contractors expressed concerns that it was becoming a problem connecting haulage tankers to the umbilical system in the field. Spillage regularly occurred leaving an overdose on the field killing the crops in many cases.
SlurryKat CEO Garth Cairns explained: "With the ever increasing size of farms in Europe, and more and more biogas plants being constructed to produce renewable energy, there has never been a greater need for specialist slurry handling equipment and innovative solutions.
"In February 2015 we supplied a 3,000m (3km), SlurryKat umbilical system complete with 15m dribble bar to a biogas plant. While the client was extremely happy with the performance of the SlurryKat umbilical system, they faced the challenge of their land being up to 40kms away from the biogas plants.
"They were using tri-axle articulated road trucks to haul the digestate to the roadside of these fields and manually hooking a transfer hose between the truck and the umbilical system pump," said Mr Cairns.
"This method encountered huge problems as the contractors found it a messy operation every time the hose was removed from the truck. Other problems were found when stopping the dribble bar in the field between each load.
