Chemicals Used in Water Well Rehabilitation -- Part 2
Well cleaning, biofilm and surface active agents are just a few of the topics McEllhiney Distinguished Lecturer John Schnieders discusses in this installment.
Pump out and recharge takes time, and time is costly. Many times the well was pumped out and put back into service with only part of the blockage removed. The use of polymer dispersants reduces the amount of acid required, limiting the concentration of the ions or dissolved solids contributed by the acid. It also promotes the dissolution of more deposit by controlling the concentration of dissolved solids, thus preventing the reprecipation.
