Hydro Cleaning is a process developed by SAFE FRAC to address the challenges of cleaning an Iron fouled well. Hydro Cleaning has also been effective in knocking out coliform and Iron bacteria.
Step 1: The well is scrubbed from top to bottom with heavy brushes
Step 2: Tremmie pipe is installed to the bottom of the well
Step 3: Heavy debris is flushed from well with clean water
Step 4: Chemistry is pumped from the bottom up, to 125% of the well's volume
Step 5: Tremmie pipe is removed, and the well is rescrubbed
Step 6: The well is allowed to sit at rest for one hour, to ensure adequate contact time
Step 7: The tremmie pipe is reinstalled, and well is flushed clean
For years, well contractors have been taught that when it comes to knocking out bacteria, a little bleach (Chlorine) is good and more is even better. Unfortunately, that’s not true; as a matter of fact it’s just the opposite. As PH go’s up chlorines biocidale ability goes down, that’s right the more bleach you use the less your ability to kill bacteria.
