AB  - A study was designed to investigate the chemical coagulation
process for the treatment of the potato food industry wastewater of the
“Chipsy factory” located at Abi‐Sier, Egypt. The chemical
coagulants used in the study include alum, ferric chloride, calcium
chloride, ferric sulphate and Nalco as polymer. Variable doses of these
coagulants were examined to determine the optimum dose. Results obtained
showed that chemical treatment (coagulation, flocculation, followed by
sedimentation) was efficient to reduce the chemical oxygen demand (COD),
total suspended solids (TSS) and turbidity significantly. Remarkable
variation of the removal efficiency depends on the type of coagulant.
Ferric chloride and ferric sulphate were more efficient than calcium
chloride. Combination of Nalco with each of the studied coagulants
improved the removal efficiency remarkably. Reduction of 91‐94 per cent
of turbidity, 93‐97 per cent of COD, and 94‐97 per cent of the TSS was
achieved with these combinations.
