organic wastewater Applications

  • Organic Micro-Pollutants Removal

    Organic Micro-pollutants are low and trace levels of synthetic organic substances released in water through human activity. They can be found in industrial, agricultural and domestic wastewater streams. Some of the most difficult-to-treat wastewater contains micro-pollutants such as persistent organic pollutants (POPs), herbicides and pesticides, personal care products (PCPs), toxic chemicals, carcinogenic and endocrine disruptive compounds (EDCs), and emerging contaminants.

  • Removal of organic compounds & toxity for wastewater treatment industry

    Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for removal of organic compounds and toxicity. Even in situations where activated sludge treatment or powdered activated carbon is used for primary wastewater treatment, post treatment with GAC may be necessary to achieve toxicity compliance.

    Wastewater solutions for wastewater UV disinfection performance

    Problem: Prior to environmental discharge, wastewater is disinfected to ensure pathogens present in the water are inactivated. Ultraviolet (UV) disinfection is becoming a widely accepted treatment technology for wastewater disinfection due to the deleterious effects of chlorine on aquatic life. The ability for the UV light to penetrate the water is directly related to the concentration of suspended particles and organic matter in water that absorb or scatter the light.

  • Wastewater Colour Removal

    The presence of colour in water and wastewater, even a small amount, is highly visible and affects the aesthetic value. Colour is often caused by organic matter. Forms of organic content that cause colour pollution include synthetic chemical dyes, algae species and natural dissolved organics such as lignin and tannins.

  • Wastewater treatment for the meat and derived industry

    The water from this type of industry generates large amount of solids. The main sources of this waste are the phases of evisceration and blood draining, which contribute a large organic load. The application of our products is ideal for the treatment of this type of water.

  • Wastewater treatment for the tank cleaning

    The waste water from the transformation process in wineries has a high organic material content, as well as large pH variations that can be harmful to the environment. This water treatment must be carried out by using the appropriate processes.

    Wastewater solutions for ballast water treatment monitoring

    Problem: To operate safely and efficiently, cargo ships take in water to provide stability. This water, referred to as ballast, carries all kinds of bacteria, microbes and micro-algae. The ballast water must inevitably be discharged when the ship takes on cargo, often thousands of kilometers away from the port of origin, transferring pathogens and aquatic organisms that can cause serious environmental, economic and health problems.

    Wastewater treatment for the sea- and inland ports/terminals

    Facing the increasing oversea trade, the environmental protection of the oceans is becoming increasingly important. The motto of the International Maritime Organization of the United Nations in London (IMO), “Safe, secure and efficient shipping on clean oceans” confronts the shipping industry and in particular the terminal ports with growing challenges. The stored fuels, raw materials and resources of a country must not pollute the harbor water with their emissions in case of rain. Produced liquid ship waste contains oil emulsion and saline bilge water among others.

  • Residential Areas and Hostelries wastewater treatment

    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.

  • Air control for wastewater treatment aeration

    Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result, large compressors are used to force air through hundreds of air diffusion filters at the bottom of the aeration basins, providing a constant 24/7 supply of oxygen to the micro-organisms in the water.

  • Wastewater treatment solutions for fat, oil & grease

    Proper waste treatment and free-flowing plumbing lines are critically tied to one another. Of the many products marketed which claim to aid plumbing problems, MICROCAT® products are unique. They offer a combination of micro organisms, enzymes (biochemical catalysts) and other ingredients which act together naturally to soften, loosen, remove and break down greases, fats and oils in plumbing lines, sewer systems, pump stations and treatment plants, thus keeping them clean and odour free. Developed through the years, MICROCAT® products, whether dry or liquid are capable of safely and effectively loosening and digesting the troublesome substances, which clog drainage systems and cause odours. When used on a regular basis, MICROCAT® products can result in savings on operational and maintenance costs.

  • Filtration systems & solutions for wastewater treatment industry

    The removal of contaminants from untreated water has become a leading issue, due to environmental concerns and the threat of future water shortage. An effective purification process is necessary to eliminate organic, chemical or other debris to meet stringent regulations for drinking water, as well as for the chemical, industrial, pharmaceutical and science markets.

  • Wastewater treatment for the textile sector

    The kind of waste water from tanneries has a high salt content that can be diluted, but is hard to eliminate. They can also have a high organic load due to the high dirtiness, including blood, sand and manure. The water itself from these industries can vary a lot from a company to another depending on its actividad. However, a common characteristic is the high content of materials in suspension due to fibres and precipitated proteins.

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