Taking your water treatment to the Next Level

Hard water and Drilling Machines

Hard water and drilling machines are never a comfortable combination especially when the goal is to remove the most rock in the shortest amount of time with the least amount of wear and tear on the drill rig.

A mining drill rig can only do the job it is intended to do when the conditions it works in are ideal. So often they are not which leads to increased frustration and downtime with far too frequent repairs and maintenance.

If you are in the underground drilling business using ground water then you will experience hard water problems leading to costly downtime of plant and equipment – guaranteed. If you’re like most engineers you’ll just get on with the job by factoring in the necessary more frequent changes and repairs due to limescale and iron issues resulting in water box seal changes, flushing head seal changes and corrosion of the machinery’s pipe fittings.

The most effective intervention has proven to be dealing with the cause of the problem, hardness in water, rather than playing catch up dealing with the resulting problems the hard water causes.

This is much easier than it sounds with the simple installation of a NLP ‘Aqua Conditioner’. It’s placed directly in the water line.

The NLP ‘Aqua Conditioners’ have proven to solve hard water problems experienced by mining equipment in underground mines using hyper saline ground water.
