Dynamic Simulation of Water Treatment in Pulp and Paper Industry
This paper presents an overview of different modelling and simulation (M & S) methods used in water treatment. Special emphasis is on pulp and paper industry. In chemical water treatment, M & S is successfully used in control design. Hybrid models based on a cascade approach are needed in biological wastewater treatment to cover different operating conditions. Uncertainty handling needs to be i...
متن کاملMeasures taken against water pollution in the kraft pulp and paper industry.
Without reclamation of waste liquor and chemicals recovery, the kraft pulp and paper industry would constitute an enormous pollution problem. Already for economical reasons, substantial recovery is secured, however, and considerable further improvements are foreseen. Recovery is outlined in terms of cycles for sodium, calcium, sulphur, and—in a wider sense—carbon. In addition, the mechanical lo...
متن کاملApplication of ultrafiltration in the pulp and paper industry: metals removal and whitewater reuse.
In the pulp and paper industry, the water use minimization is a constant target. One way to reduce water use is to recycle the effluent in a closed-cycle concept. In paper mills, the main source of liquid effluent is the so-called whitewater, which is the excess water, originated from pulp stock dewatering and other fibre contaminated water. This research studied the reuse of paper mill whitewa...
متن کاملIntegrated Membrane Processes (EDR-RO) for Water Reuse in the Petrochemical Industry
The objective of this work was to apply a hybrid process, including electrodialysis reversal (EDR) and reverse osmosis (RO) to the treatment of petrochemical wastewater in order to obtain process water for reuse. A water balance was carried out to defne the main water consumers and the process step that could receive the produced water. Additionally, toxicity assays wer...
متن کاملWater Reuse
minimizing their wastes. The concept of such minimization, recycling, zero discharge (all aspects of the same reuse philosophy) is appealing and straightforward. The reality often is not: In some cases a highly organic wastewater, as from a paper mill or a food processing facility, has to be converted to a highpurity stream. As if this is not challenge enough, such treatment must be consistent,...
