Mean TKN concentration was 26.25 and 4.17 mg L-1 in the raw and treated ,wastewater,, respectively, but the different between the ,two, was significant (LSD 0.05 = 2.93). The reduction in TKN in the treated effluent could be due to the decomposition of organic nitrogen from ,wastewater, to other forms of nitrogen such as NH 4 , NO 2 and NO 3 in the treated water using different materials in the system.

A two-stage treatment process using chalk (CaCO 3) and lime (CaO) is used. In the first stage, the acidic waste water is neutralized with chalk to pH 3.5 – 4.0 allowing a reaction time of 30 minutes with adequate agitation. More than 85% of fluoride can be precipitated as calcium fluoride, with marginal phosphate removal.
