Big Air rifle - OH Yes!!

Well I am into the processing of sewage, clean it, remove solids and process them for farm use.

 

We have a machine to dry the product sludge (****). Then add lime to kill E coli. The lime causes the product to heat up and the kill percentage will be reached. Unfortunately we had a large quantity of lime added to the product. This had the effect of excessive drying of the sludge and caused a blockage in an output pipe.

Well the pump pushing it up the pipe increased in pressure and after a while a standby air compressor also fed in high pressure air to the pipeline.

Sooo.. A slug in a pipe with high pressure behind it? Well that's an air rifle is it not? A big one!

 

So it spat out a 5kg, 8inch diameter slug that hit a parked up JCB, at 15m it shattered the side window and cracked the forward window. This caused a load of razor sharp high speed shards to fill the JCB cab, lucky the driver was not in the cab at the time. It also spat out a load more product to 25m.

I have had to fill in so many reports and investigations I feel sick!

 

Here are the piccys!
