  • Ozone generators for aquaculture applications

    Ozone provides both economical and ecological advantages to the Aquaculture industry. Ozone oxidation of aqua-farms improve water quality, destroys organics,  and increases DO levels which result  in faster growth rates, decreased death tolls, and provides an overall healthier and safe environment for fish.

    Online water analysers for pure/high purity water

    Pure water and high purity water are crutial factors of production in numerous processees and industries. Depending on the demand it is used as a raw material, auxiliary or operating material. Doing this, it is very important to pay particular attention to the quality of the water, because this is crucial for product quality and safe operation of the production facilities. Therefore, continuous monitoring is essential - from an ecological as well as economic point of view.

  • Treatment and dewatering of rejects for pulp and paper industry

    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.

  • Thickening and dewatering of sludges for water and wastewater industry

    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 screw press BELLMER KUFFERATH Machinery offers plant and equipment able to dewater structured sludges to maximum dry contents.

  • Become compliant with the EU Water Framework Directive

    The WFD is the most substantial piece of water legislation ever produced by the European Commission, and will provide the major driver for achieving sustainable management of water in the UK and other EU Member States for many years to come. It requires that all inland and coastal waters within defined river basin districts must reach at least good status by 2015 and defines how this should be achieved through the establishment of environmental objectives and ecological targets for surface waters. The result will be a healthy water environment achieved by taking due account of environmental, economic and social considerations.

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.
