PeCOD Analyzer Improves Pulp Mill Performance, Reduces Wastewater Pollution. MANTECH’s PeCOD technology is a safe and effective solution for improving wastewater treatment and optimizing the use of chemicals in pulp and paper mills.
Paper manufacturing involves many chemical processes that drive the emission of nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon dioxide (CO2). Nitrogen dioxide and sulfur dioxide are major contributors of acid rain, whereas CO2 is a greenhouse gas responsible for climate change. In addition, wastewater discharge for pulp and paper mills often contains alcohols, chelating agents, and inorganic materials like chlorates and transition metal compounds. Furthermore, chlorine and compounds of chlorine are used...
Pulp and paper mills produce large volumes of wastewater and residual solids, presenting a number of issues in relation to pulp and paper wastewater treatment, discharge, and sludge disposal. We understand that you are seeking wastewater treatment that reliably meets permit limits, while minimizing costs, and maintaining consistent production. We will work with you to find an effective way to optimize oxygen dispersion, reduce sludge accumulation, and eliminate the need for costly dredging.
Water is required in almost every step of the production process of pulp and paper. The wastewater streams vary greatly in concentration and composition (e.g. COD, BOD, suspended solids, wood extractives, sulphur, pH). Due to stricter rules and regulations with regard to fresh water intake and wastewater discharge, efficient water management has become essential to the industry.
Companies around the world are driving forward digitalization and the paperless office is regarded as the ideal from both an economic and an ecological point of view. The actual development of paper consumption is in surprising contrast to this goal. According to the Federal Environment Agency, paper consumption is at a high level not only in Germany but also worldwide and continues to rise.
Fresh water is increasingly expensive and the pressure grows on the available water supplies as the world population grows and the climate changes. Alternatives for the water balance in factories are eagerly sought after. Besides the higher costs for fresh water, the costs for discharging water go up as well. Reusing wastewater kills two birds with one stone: it reduces fresh water intake and the discharge of wastewater.
As most of the largest industrial users of water, the paper and pulp industry have long treated water in accordance with environmental permits. Water is used in all major process stages, including raw materials preparation, pulp washing and screening and paper machines. Water is also used for process cooling, materials transport, equipment cleaning, general facilities operation and to generate steam for use in processes and on-site power generation. Lenntech provides sustainable complete solutions for ingredient,...
We design and implement water treatment plants. Among these plants are plants that treat industrial process water and condensation water from power plants in pulp and paper, and forest industry. Close cooperation between the client and Econet ensures the highest quality result that fully meets the client’s needs. We continuously aim to develop our operating methods and cooperation models in order to offer our clients the best possible service during the project, and in the future. Econet Group`s services...
During the chemical production process, the solid-liquid separation requires such features as high handling capacity, large separation factor, optimized screw structure, good machine corrosion resistance, closed separation environment, etc. During the chemical reaction process, centrifuge for chemical industry can rapidly complete separate, reduce the time of side reaction or reverse reaction, and effectively increase the yield rate of reaction.
Bioaugmentation consists in an increase of selected bacteria that will help naturally the process of biological degradation of organic compounds.
BIODIGESTOR can be applied in the biological treatment of an industrial waste-water treatment, like pulp & paper, increasing its efficiency.
Paper companies consume large amounts of water in the production process and hence, produce high dumped flow rates. This type of industry also tends to produce the development of filamentous bacteria. The effluent to be treated from wood industries has high loads with elevated solid matter content.
Being an industry where large quantities of water are used, the pulp & paper is a key sector for the application of IDRAFLOT. IDRAFLOT can be applied for the process water treatment (pre-treatment or tertiary treatment), and for the separation of fibers and suspended solids in the wastewater treatment.
Stock Thickening: Between Primary and Secondary Refining Stage. Between Secondary and Tertiary Refining Stage. In Front on High-Density Stock Chest. In Front of Dispersion Systems in Recycle Mills. Pulp Washing for Pine Tar and Chemical Removal.
Polyacrylamide is mainly applied for seven aspects in paper industry: Enhance the retention of added substance and dyestuff to decrease the loss of raw material and the pollution to environment. Improve the dry-strength and wet-strength of paper. As dispersant of macrofiber paper making. Raise up the Stability of Pulp. As adhesive of Paper Coated Dyestuff. As decorative adhesive of Paper. Used for wastewater treatment from the paper industry.
Wastewater treatment processes considered for this industry must address industry specific nuances like slug discharges of pulp, stormwater runoff and air emissions for compounds such as total reduced sulfur (TRS)
The paper industry is an industry that requires large amounts of water and energy. There are significant amounts of water consumption in a range such as 15-100 m3/ton in paper pulp production facilities.
