Primary treatment Watercare. Abstract. Chemically enhanced primary treatment (CEPT) has been in use for more than 100 years. However, it fell into disfavor in the 1930s when compared to biological treatment because the large concentrations of metal salts produced large quantities of sludge., PDF ABSTRACT. ABSTRACT. Tertiary treatment of municipal wastewater by dissolved air flotation was studied on a pilot‐scale. The effects of coagulant dose, flocculation pattern, dispersion water recycle ratio and hydraulic surface load on process performance were evaluated. The treatment of primary effluents by dissolved air flotation was investigated to assess the suitability of this process.
