Waste Water Treatment Solutions in Pulp and Paper Industry
In the Pulp and Paper industry a lot of effort is used to water saving and closing water circuits, and to reduce substantially the environmental impact, by process modeling and Kidney technologies as internal process water treatment. Effluents from pulp and paper mills contain solids and dissolved matter.
Roughly 30% of pulp stock ends up as white water. Treatment of the white water is necessary for its important reuse in other areas of the plant. pH control is the most efficient method to treat reclaimed white water. Instrumentation A number of different sensors can be used to monitor the pH of white water.
Pulp and Paper Control: ClO2, white liquor, white water
Optimize your Pulp and Paper Process in all Stages. Besides wood fibers, water is the most important raw material in the pulp or paper mill. Simply put, pulp and paper manufacturing is impossible without water at every step of the production process. optek offers analysis solutions to paper mills covering the whole production process including raw water- and effluent monitoring plus bleaching
The method of using a multi-disc filter as white water treatment equipment has been widely applied to pulp and paper mills around the world, and has received a very good white water treatment effect. The white water treated by the disc filter can be directly recycled, thereby increasing the degree of recycling of the white water.
Water Management in Paper, Pulp and Board Mills
Water Management in Paper, Pulp & Board Mills This good practice guide deals with a number of issues faced by organisations operating paper and board mills and wishing to identify and implement process improvements, in particular, the reduction of water and chemical usage, and wastewater and effluent costs.The UK paper industry is a major water user and is under increasing pressure to improve
Water-reuse and waste-to-energy technologies can lessen environmental impact. The pulp and paper (P&P) industry is one of the largest users of water in the industrial economy of the United States. It requires an average of 54 m 3 of water to produce a metric ton of pulp or paper, and almost all phases of manufacturing require water. On the downstream side, P&P mills also create difficult-to
Treatment of pulp and paper mill wastewater—a review
Pulp and paper mills generate varieties of pollutants depending upon the type of the pulping process. This paper is the state of the art review of treatability of the pulp and paper mill wastewater and performance of available treatment processes. A comparison of all treatment processes is presented.
internal treatment methods for white water at pulp and paper mills include fi ltration, fl otation, and membrane techniques such as ultra-fi ltration. Also some evaporators can be found.

Water Treatment In a world where water is an increasingly precious resource, accurate and appropriate treatment and conservation of water is increasingly complex and imperative, SEKO’s expertise delivers solutions suitable for the whole water cycle for human or industrial use while our engineers and researchers have developed products and accessories to meet and exceed the ruling national or
Treatment of the Bleaching Effluent from Sulfite Pulp
Waste water reuse is a globally imperative component of sustainable water management [1]. The pulp and paper industry produces substantial volumes of polluted waste water [2] (~220–380 m 3 per ton paper [3]) and is also one of the largest consumers of fresh water (~273–455 m3 per ton paper [3]) [1,4,5] (Figure 1).
technical and specialty paper mills which consume up to 100 m³/t on an average of 40 m³/t. In older mills, the specific waste water volume can be higher due to suboptimal process design.
