  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.

  • Biological wsatewater treatment for dairies

    Dairy raw wastewater is characterized by high concentrations and fluctuations of organic matter and nutrient loads related to the discontinuity in the cheese production cycle and machinery washing. Because the dairy industry is a major water user and wastewater generator, it is a potential candidate for wastewater reuse. Biowater’s wastewater system is based on highly efficient biofilm technology and is ideal for this type of application, one that requires pretreatment prior to discharge to a municipal sewage system.

    Real-time Control System for Wastewater Treatment Plants

    Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

    In order to meet the operational demands of modern-day plants, a new control system was developed. Proprietary control algorithms were introduced based on a large set of data from nutrient measurements in various WWTPs. The customer`s benefits are twofold: (1) achieving optimum effuent quality and, at th same time, (2) lowering energy needs and dosing of commidity chemicals.

  • 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.

  • BOD and COD Removal

    Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g., pesticides, plasticizers, resins, coolants, and dyestuffs); Pretreatment of high strength / low flow wastewaters – where biotreatment may not be practical – prior to discharge to a Publicly Owned Treatment Works (POTW);Enhanced separation of entrained organics by flotation and settling processes; and Supply of supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure.
