The Select Industries THPS Ball is a water soluble iron sulfide dissolver in solid ball form.


THPS BALL are recommended for control of iron in oilfield water as well as petrochemical and other
industrial waters.
Benefits have also been seen by treating oil/water tanks with THPS BALLS.


THPS BALLS are typically applied in a slug treatment at concentrations of 500-1000 ppm, based on
the volume of fluid to be treated.
Following the initial slug treatment, THPS BALLS can typically be applied at concentrations of 25-100
ppm on a maintenance treatment schedule.
The concentration and treatment frequency will depend on well conditions including fluid volume,
depth of the well, and severity of the iron problem. Optimum treatment is determined by close
monitoring of the well conditions.
