1/5/2015, · Hydrogen sulphide is formed under conditions of deficient oxygen in the presence of organic materials and sulphate [25]. This is the reason for high sulphide measured in the effluents under analysis. High alkalinity increases with wastewater strength. It shows the capacity of waste waters to neutralize acids, but it is undesirable.
