wastewater treatment residual Applications

  • Electrodeionization

    The Fractional Electrodeionization (FEDI) process is an advancement of conventional EDI. The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant& design economics and reliability. By incorporating a two-stage separation process with different voltages the FEDI process is able to: Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus...

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine,...

    Industrial wastewater solutions for container cleaning wastewater

    Flexible, turnkey solutions for container cleaning. Cleaning industrial containers such as canisters, vats or IBCs produce large volumes of effluent. The type of impurities in this effluent depends heavily on what has been transported in the containers. That’s why effluent treatment requires a flexible system able to cope with all conceivable contaminants. Reconditioners are increasingly using modern vacuum distillation systems to do this. They work fully automatically, guarantee a high level of process...

    Aeration and mixing technologies for pulp and paper treatment

    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 treatment systems for chemical industry

    The effluents that accrue in the cleaning process of silo vehicles and containers for transportation of raw materials for the chemical industry, are highly complex and constantly changing in the composition of wastewater. Flocculation as the prior art of treatment for chemical waste water can not remove many of the completely dissolved invisible substances. Thus, the residual stresses are evident despite high claritv of the `Treated effluent` is often well above the levels witch are applicable for wastewater...
