TREATMENT TO SICK WELLS
Generally the yield of the tubewell is reduced by chemical and biological encrustation of the well screens and the formation materials around the intake portion of the well. Environ Tech Labs under take the job of well rehabilitation of sick tubewells by restoring well yield to its most efficient condition. The sick wells are given various chemical treatments depending on the type of encrustation which often forms hard brittle, cement like deposit. Generally following type of encrustation are observed:
- 1) Precipitation of calcium and magnesium carbonates/ sulphates.
- 2) Precipitation of iron and manganese compounds primarily their hydroxides or hydrated oxides.
- 3) Plugging caused by slime producing iron bacteria or other slime forming organisms (biofouling). Depending upon nature of deposition / encrustation best suited treatment is given to the well. The disinfection of tubewells/water storage tanks is also taken up effectively and safely.
