Activated Sludge Treatment of Paper Mill Effluents
Introduction The pulp and paper industry is the second largest industrial water consumer in Europe with a usage of 35 m3/ton paper and a production of 85.2 M tons/year. Its effluents cause considerable damage to the receiving waters if discharged untreated since they have a high biochemical oxygen demand (BOD), chemical oxygen demand (COD) and contain chlorinated compounds, suspended solids (ma...
متن کاملUsing Paper Mill Sludge and Compost in Potato Production: Firs
Introduction and Research Objectives Use of organic by-products as soil amendments in agricultural production exemplifies a strategy for converting wastes to resources. Paper mill sludge is one of the largest underutilized organic by-products in Wisconsin. Paper mill sludge (PS) generation in Wisconsin increases approximately 5% per year, and 70% of all PS generated currently (740,000 dry tons)...
متن کاملAdsorption of Phenolic Compounds onto the Activated Carbon Synthesized from Pulp and Paper Mill Sludge: Equilibrium Isotherm, Kinetics, Thermodynamics and Mechanism Studies
A new activated carbon was produced from pulp and paper mill sludge as a low cost precursor via chemical activation by zinc chloride. The activated carbon was successfully used for the adsorption of phenol and two of its derivatives, i.e. 2-chlorophenol and 4-nitrophenol from aqueous solutions. The characterization of the prepared activated carbon demonstrated high textural properties for the s...
متن کاملStudy on Drying Kinetics of Paddy Rice: Intermittent Drying
The intermittent drying characteristics of an Iranian popular paddy rice variety were experimentally investigated to determine the drying kinetics and obtain the effective moisture diffusivity. A lab-scale fluidized bed dryer was designed and constructed to enable obtaining the required results while controlling critical drying parameters. The effects of drying temperature and tempering per...
متن کاملSludge Dewatering by Impulse Drying
An innovative and energy efficient sludge dewatering technology has been developed. The technology, impulse drying, involves briefly contacting the sludge under pressure with a heated surface. A unique feature of impulse drying is that the majority of moisture removal occurs as lipid water. A pilotand laboratory-scale demonstration was performed on low ash primary paper mill sludge. The pilot-s...
