Dewatering rejects to maximum dry contents represents an essential process step both from an economical and ecological viewpoint, especially in waste paper based paper mills but also in pulp mills. The following goals shall be achieved: high heating value for stable and ecological incineration without co-firing, reduction of landfill and transport charges.
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.
Both economic and ecological demands make maximum dewatering of sludge a most crucial step in the process flow, especially for the pulp and paper industry with their large quantities of sludge to handle. A highest possible dry content of dewatered sludge minimizes weight and volume, hence achieving the following objectives: reduction of transport and disposal cost. high heating value for incineration without additional fuel. With the sludge dewatering systems including both AKSE S disc thickener and AKUPRESS BX...
Hiller machines provide world-class standards for of high-performance decanter centrifuges specially equipped for the separation requirements of the ethanol, biodiesel and other renewable energy industries.
The preparation of plastic waste is an important process both for protection of raw materials as well as for reduction of waste. In this context, BELLMER KUFFERATH systems can be applied for all kinds of operations containing wet preparation processes.
In customer-specific chemical processes, explosive and corrosive solvents are used to systematically change the stock characteristics of e.g. pulp or plastic which calls for appropriate measures to protect the machine as well as the environment. To meet such requirements, BELLMER KUFFERATH Machinery has adapted their screw presses` proven functional concept to suit special requirements, such as:
Separation and dewatering of suspensions are important process stages in treating waste and digester output. BELLMER KUFFERATH machines, within an overall waste management concept, divide waste streams into separate streams in waste treatment plants, for which specific treatment methods make sense. Apart from single machines, BELLMER KUFFERATH also supply complete systems for sorting and dewatering of waste streams.
