Fat, Oil and Grease treatment

by Ecochemicals UAB     based in Kaunas, LITHUANIA

Industrial and municipal waste contaminated with fat – a frequent problem for companies maintaining wastewater network infrastructure and municipal wastewater treatment facilities. We recommend the use of GREASOLUX fat dissolvent cartridges to avoid the problems of pipeline chocking, equipment damage, offensive odors, formation of filamentous bacteria, poor wastewater treatment results, poor sedimental properties of activated sludge. GREASOLUX – is a cartridge that slowly dissolves in water, enriched with special fat dissolvent microorganisms and enzymes. GREASOLUX – is an especially efficient product for low cost solutions to problems caused by fat: only few strategically placed cartridges will remove or minimize the problems caused by fat.

Wastewater treatment for the beverage industry

by DAS Environmental Expert GmbH     based in Dresden, GERMANY

Enterprises in the beverage industry are facing tough competition. Water consumption is one of the most significant cost factors in the sector, since water is the main ingredient of their products. In addition, bottle washing or cleaning of machines and equipment also requires enormous amounts of clean water. This is why beverage producers need a wastewater treatment system that meets these demands.

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.

Residential Areas and Hostelries wastewater treatment

by Sistema Azud, S.A.     based in Alcantarilla, SPAIN

Residential Areas and Hostelries wastewater, including water generated by domestic use, by shops, restaurants and laundries, must be adequately treated to meet the discharge requirements of public sewers or channel, or reuse as irrigation water mainly.

This wastewater has the following characteristics:

  • Variations in flow depending on the time of day and season (mainly in tourist areas).
  • High suspended solids content.
  • Presence of oils, fats and detergents.
  • High concentration of easily biodegradable organic matter.
  • Adequate concentration of nutrients.

Wastewater treatment upgrades & extensions

by DEVISE ENGINEERING S.A.     based in Athens, GREECE

The time comes that a Sewage Treatment Facility Municipal or Industrial may require significant upgrading or even an extension. The upgrade usually concerns improvement process performance (removal rates) and efficiency as well as replacement of mechanical equipment. The plant expansion usually refers to an increase of the capacity or to the extension of treatment ability, ie adding Nutrient Removal.

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.

Monitoring industrial trade discharge for wastewater treatement industry

by Pollution & Process Monitoring Ltd     based in Sevenoaks, UNITED KINGDOM

Industry has had to respond to the requirements of progressive environmental legislation such as the Urban Waste Water Directive, IPC, IPPC and now the EPR (Environmental Permitting Regulations). As successive legislation becomes more stringent, discharge consents have been progressively tightened, and the need for self-regulation has become more important. As a consequence, on-line instrumentation has been installed throughout waste-water industry to continuously to provide trade discharge monitoring and perform continuous water analysis for key consent parameters.

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.

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
