The waste water can be from urban, domestic or industrial origin, being numerous the products or agents that can be transported in them, such as: The process consists on two phases. In the first one, the settled sludge by the action of anaerobic organisms produces hydrogen sulphide SH2. In the second phase, these SH2 gases are fixed in the internal surface of the pipe, wet by condensation.

In this second phase and in these not flooded surfaces, the aerobic bacteria Thiobacillus give rise to the production of sulphuric acid H2SO4according to this reaction:.

The hydrogen sulphide is also the gas which volcanoes release, it is yellow and with a strong smell like rotten eggs, this gas is toxic for human beings and has caused the dead of many operators of the maintenance equipment of sewerage networks. That is why it must be avoided to climb down to the sewer pipes, what can be achieved with the modern systems of inspection by a robotized TV video camera and by cleaning the sewer pipes at the level of the floor.

Likewise, the sulphuric acid is a extremely corrosive chemical compound. The pipes more affected by the corrosion because of the sulphides, are those who have cement in their composition, dde the concrete, asbestos cement and foundry, whose internal protection is given by a thin sheet of cement mortar.

The pipes and metal structures are also affected by hydrogen sulphide and sulphuric acid. The hydrogen sulphide reacts directly with many metals like iron and copper. Water Research Centre Both the manyal document that it is in English like the second one which is in Dutch must be more updated at present. What is important is to know that there are specifications to evaluate, classify and categorize the problems that we face in the sewerage networks.
