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.

Biological wastewater processes for chemical & pharmaceutical

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

This waste stream can have complex characteristics: Biocides, heavy metals, pharmaceutical intermediates and endocrine disruptors. We are familiar and know how to marry appropriate treatment to make sure you are compliant.

Biological wastewater processes for petrochemical

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

This wastewater typically contains a lower biochemical to chemical oxygen demand.  We determine biodegradability of each waste stream and the presence of toxic or inhibitory compounds.

A well-designed wastewater plant starts with your effluent requirements and an energy-efficient biological process. WesTech has multiple biological process options to match your application and preference. From trickling filters to oxidation ditches, WesTech`s biological process equipment will give you the effluent quality you need and the foundation for a successful wastewater plant.

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 wastewater processes for municipal treatment plants

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

Biowater have knowledge and competence to help in designing and building new systems and upgrade existing infrastructure based on biotechnology as CFIC, MBBR and IFAS solutions.

The Company offers cost-effective solution that allows municipal plants to both increase their treatment capacity and upgrade the effluent quality with minimal civil works.

Biological wastewater processes for pulp and paper industries

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

Wastewater treatment processes considered for this industry must address industry specific nuances like slug discharges of pulp, stormwater runoff and air emissions for compounds such as total reduced sulfur (TRS)

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.

Sludge reduction for industrial wastewater treatment

by Pieralisi Group     based in Jesi, ITALY

The wide range of Pieralisi decanters is in fact successfully used by over 15,000 customers around the world for the volume reduction of biological and physical/chemical sludge of both Municipal and Industrial origin.

Chemical filtration in water for the wastewater industry

by atech innovations gmbh     based in Gladbeck, GERMANY

In the field of waste water treatment atech membranes are used, for example, for the filtration of cleaning chemicals (surface treatment), for cell separation after biological processes, or for the recycling of paints and lacquers.

Filtration solutions for wastewater treatment industry

by Filtralite Saint-Gobain Byggevarer As     based in Alnabru, NORWAY

Filtralite is suitable for use in different effluent water treatment processes, both for municipal and industrial effluents, such as: Biological treatment, Tertiary filtration, Odour treatment.

Wastewater solutions for municipal sewer control

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: A significant portion of the operational costs of a conventional municipal wastewater treatment plant employing an aerobic biological treatment unit comes from electricity costs associated with aeration. In many cases, the aeration rates are kept at the maximum level to ensure that the plant’s effluent is in compliance with the regulations. The critical parameter for regulatory purposes and treatment efficiency, BOD, takes 5 days to measure through standard methods providing almost no value to the plant operators in terms of adjusting aeration rates and chemical dosing.

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.

Wastewater Treatment for Aquaculture

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

Wastewater treatment for aquaculture will typically consist of processes for removal of major pollutants such as organic matter, suspended solids, ammonia nitrogen, dissolved gases and bacteria/virus. Typical unit processes may include: Biological treatment Solids removal Disinfection

BOD and COD Removal

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

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. http://www.h2o2.com/industrial/applications.aspx?pid=104&name=BOD-COD-Removal

Sludge reduction for municipal wastewater treatment

The wide range of Pieralisi decanters is in fact successfully used by over 15,000 customers around the world for the volume reduction of biological and physical/chemical sludge of both Municipal and Industrial origin.

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.
