Effect of nutrients supplementation on anaerobic sludge development and activity for treating distillery effluent.
Startup of laboratory anaerobic reactors and treatment efficiency were investigated by supplementing the distillery effluent feed with macronutrients (Ca, P) and micronutrients (Ni, Fe and Co) under mesophilic conditions. Calcium and phosphate were deterimental to the treatment efficiency and sludge granulation. Traces of salts of iron, nickel and cobalt, individually and in combinations improved the COD removal efficiency and sludge granulation process.
