[Gox]

What is your opinion about MASTERSEAL SP120 & HDPE can those materials be successfully used as a internal coating/lining material for concrete based tanks subjected to the acidic waste water. Waste water has following ingredients concentration: Cadmium (0.00087); Chlorine (12.3); Chromium (0.048); Copper (0.032); Iron (2.0); Lead (0.0093); Manganese (0.069); Nickel (0.054); Sulphate (182); TSS (55.4); TDS (216); Zinc (2.2); pH = 3....respective concentarions are expresed in ppm.
Also other suggestions about suitable materials would be greatly appreciated.

Thanks

Nope, Chlorine means (CL2) molecul....chloride ions are chlorides.
Appreciate any further opinion.
