Corrosion Prevention at HCL Technologies

The source of the problem was an open drain containing untreated waste/sewerage water which blanketed the whole area with an obnoxious, foul odour. The odours were caused by the presence of hydrogen sulphide gas in methane, which is continuously  generated due to the gradual degradation of organic material in the sewerage and the land fill. (Methane, on its own has no odour
and thus, is not considered as a contaminant). This was causing break down of computer systems and servers, disrupting work and resulting in loss of business. To add to the woes, people working in the plush air conditioned HCL office were feeling extremely uncomfortable leading to loss in productivity.
