Microbial testing for biological wastewater treatment industry

by LuminUltra Technologies Ltd.     based in Fredericton, NEW BRUNSWICK (CANADA)

Realize a new level of process stability and efficiency! Wastewater operators have traditionally had no choice but to rely on TSS or VSS measurements to quantify biomass in their process. These measurements detect much more than just living biomass and therefore are inaccurate and unresponsive indicators of the living population.

Biological wsatewater treatment for dairies

by Biowater Technology     based in Cumberland, RHODE ISLAND (USA)

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.

Biological wastewater processes for mining

by Biowater Technology     based in Cumberland, RHODE ISLAND (USA)

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.

Drinking Water Treatment

by AnoxKaldnes AB - a Veolia Water Company     based in Lund, SWEDEN

The AnoxKaldnes™ MBBR technology is an ideal solution for treatment of potable water whenever there is a need for removal of biologically transformable pollutants, such as NH4+, NO3- or organic compounds. In most cases, pollution levels in drinking water are relatively low, putting demands on a biological process to be able to maintain a high concentration of active microorganisms despite low incoming substrate concentrations. The fixed-film of AnoxKaldnes™ MBBR fulfills this very well and is successfully applied for removal of pollutants in concentrations of a few mg/L.

Real-time Control System for Wastewater Treatment Plants

by AppliTek NV - Environmental Analysis Division     based in Nazareth, BELGIUM

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)

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

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.

Wastewater treatment solutions for controlling filamentous microorganisms

by QM Environmental Services Ltd.     based in The Hague, NETHERLANDS

Wastewater treatment plants can on occasion experience problems with settling of the biological sludge in the secondary clarifier. Often this problem is caused by the abundant presence of filamentous microorganisms.

Waste to Energy

by Babcock & Wilcox MEGTEC     based in De Pere, WISCONSIN (USA)

We can treat the air streams from waste management plants, MBT (Mechanical Biological Treatment) reception and composting areas, Waste Water Treatment Plants (WWTP), Refuse Derived Fuel (RDF) Plants, gasification of waste, syngas, torrefaction, gas engines and biogas upgrading. In waste management plants and WWTP, we remove the odors that may be causing a nuisance to neighbors, with bioreactors using Biomass to degrade odorous components and where odors are particularly intractable or VOC emissions higher, thermal oxidizers to meet prescribed emission limits and odor levels. In RDF Plants, Syngas, Gasification, Gas Engine and Biogas Upgrading applications, we employ thermal oxidizers, particulate removal and DeNOX systems, for the control of VOC, NOx, CO and particulates to prescribed emission limits.

Wastewater treatment for the food industry

by DAS Environmental Expert GmbH     based in Dresden, GERMANY

Companies in the food industry need large amounts of water – as an ingredient of their products, but also – in large amounts – for the production process and for the cleaning of raw materials, machines and equipment. Water cleans, washes and is processed. Using this essential resource carefully helps to reduce costs. The biological wastewater treatment process by DAS Environmental Expert enables companies to recycle usage water and therefore lower overall consumption.

Wastewater Treatment for the Chemical industry

by HydroThane STP BV     based in KC `s Hertogenbosch, NETHERLANDS

In addition to the food industry, biological anaerobic and aerobic technologies can be applied in the chemical and pharmaceutical industry as well.

Typical for the chemical and pharmaceutical waste water is the high organic pollution, which is often limited to only a few components that can be present in high concentration. Every production site has its own unique effluent composition.

This type of effluents require tailor-made solutions. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type waste water.

Some chemical /pharmaceutical production processes where anaerobic technology has been applied are:
- Purified Terephthalic Acid (PTA)
- Phenol
- DMT
- Penicillin
- Insulin.
