wastewater toxicity Applications

  • Waste water respirometry solutions for toxicity tracking

    If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be...

  • Waste water respirometry solutions for toxicity testing

    If industrial wastewater entering a treatment works contains toxic components the rate of biodegradation will be inhibited or stop completely. This can result in failed consents and will certainly give rise to operational problems. Visible indications include deflocculation, bulking and the appearance of filamentous bacteria. Sometimes, there are no visible effects. When the sludge bacteria are inhibited, there is the possibility of toxicity carryover in the effluent that is discharged to receiving waters. With...

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...

  • Waste water respirometry solutions for toxicity reduction tests

    In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

  • Wastewater evaporator Solutions for the printing wastewater treatment

    Printing and Photo Processing Wastewater Treatment and Disposal. The printing industry and photographic processing produce a tremendous amount of waste water, from washing prints, cleaning between color changes, cleaning ink shipping containers and cleaning ink delivery systems. The wastewater produced is often contaminated with heavy metals and other highly toxic materials.

    Determination of zinc in water by fluorimetric method

    In accordance with WHO’s Guidelines for Drinking Water Quality there is no health-based guideline value of zinc in water concentration. Concentration of zinc in tap water can increase as a result of its dissolution from pipes. Also, elevated levels of zinc may be an indicator of increased concentrations of other toxic metals; thereby zinc in water analysis is an essential analytical task. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of zinc in...

  • 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.,...

  • Water intake protection monitoring for wastewater treatment industry

    Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.

  • 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...

    Determination of anionic surfactants in water by fluorimetric method

    Anionic surfactants (A-SAS) represent, by volume, the most important group of surfactants used in cleaning products and the oldest and the largest volume anionic surfactant is soap. In concentrations 0.1 ~ 1.0 mg/L A-SAS become toxic for aquatic environment. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of anionic surfactants in water samples using the FLUORAT-02 analyzer. The method became the Interstate standard for anionic surfactant in water...

    Drinking water treatment

    Drinking water can be produced from any natural sources like groundwater, lakes and rivers (surface waters) or seawater. Drinking water standards are set by the World Health organisation or by the European Union. Drinking water must be free of suspended solids, microorganisms and toxic chemicals. Mineral concentration recommendation vary from country to country but most of the minerals have a maximum concentration recommended to ensure safe, equilibrated and pleasant water to drink.

    Phosphorimetric determination of uranium in water

    Introduction

    The presence of uranium in water causes radiological pollution as all uranium radionuclides decay by both alpha and gamma emissions. Chemical aspects of uranium toxicity include mainly nephritis and other renal diseases. Mentioned harmful features affect on humans even in low concentrations thus requiring sensitive analysis methods.
