Problem
A while ago around 2006 we installed a borehole pump to supply the hotel and spa but over the last few months, it seemed to be producing a far lower flow- of bright orange water- than the 6m3/h it gave originally. We concluded that professional help was required and were recommended to contact Proquip Direct.
Cleaning Operation
Proquip made an initial visit to access the situation and found the flow to be only 4m3/h - concluding that the problem was caused by iron bacteria choking the well and pump.
They returned to treat the well one Thursday morning and added 70kg of their I-GON borehole cleaner to the water while circulating it back down the hole. They kept the pump running for an hour and then left it off overnight to allow the I-GON to dissolve the Iron Fouling. After 24hours the pump was re-started and the water run to waste for a couple of hours before testing the flow again. This was now found to be back to 6m3/h and the water was clear.
Conclusions
The cleaning of the borehole with I-GON achieved the desired results of removing the Iron Fouling from the pump and cleaning the screen….. we would be happy to recommend this treatment for anyone else with a well in a similar state.
Yours Sincerely
