  • Final effluent monitoring for wastewater treatment industry

    Industry and municipal waste-water (sewage) treatment plants have had to respond to 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 final effluent monitoring and perform water analysis for key consent parameters.

  • Real-time In-situ Effluent Monitoring

    The UviLux BOD Indicator enables in-situ, real-time, reporting of BOD within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units. The principle behind the measurement is the excitation of Tryptophan-like fluorescence within UV wavelength band, which has been shown to correlate with both BOD and bacterial contamination. With complete flexibility of deployment methodology, the UviLux BOD Indicator can be applied to both water supply and water recovery processing plants. For water supply processing, the UviLux BOD Indicator can be applied at the front end to the water intake to provide alarm of any contaminated water entering the plant. Applications within Waste Water Treatment Works can include monitoring of effluent levels at the final outflow point (into rivers and coastal areas) as well as the primary, secondary & tertiary stages, the data potentially feeding into energy saving systems to optimise process performances. The CTG UviLux BOD Indicator in-situ fluorometer can also be used within pipe and channel networks to test for incidences of black water and grey water cross-over.

    Wastewater treatment for Medium & Large STPs

    DEVISE has developed “Smart Treatment Solutions” for larger capacities plants. Medium size STP’s up to treatment capacity of 2,300 m3/d (11,500 P.E.) are possible to implement with Packaged Systems. DEVISE is currently implementing such a STP using its revolutionary “Ultra-Clear Bio-Plant” technique which would produce an effluent quality suitable for re-use.

    Wastewater Treatment for the Bioenergy Industry

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

    The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

    Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. 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 of waste water.

  • Water treatment for landscape

    The sources of water for traditional landscape irrigation are many. They include municipal water, groundwater, and surface water; treated municipal wastewater treatment plant effluent properly treated to the standards of quality required for irrigation; and ever-increasing harvested rain, gray and storm waters. Issues confronting the landscape irrigation market range from treatment of alternate supplies to addressing iron removal in order to provide suitable quality water for any given landscape irrigation application. With our experienced staff of irrigation industry professionals, and in cooperation with landscape architects and consultants, we have the expertise and flexibility to select the best, most cost-effective solution for addressing any landscape market irrigation water treatment application.

  • Process design & engineering services for water treatment industry

    Waste water is any water that has been adversely affected in quality by anthropogenic influence. Municipal wastewater is usually conveyed in a combined sewer or sanitary sewer, and treated at a wastewater treatment plant or septic. Treated wastewater is discharged into receiving water via an effluent sewer.

    Wastewater solutions for municipal sewer control

    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.

  • Evaporators technology for waste & recycling industry

    The leachate produced by the waste in the landfill is an extremely pollutant effluent that requires high effective treatment processes to comply with the very strict limits for discharging operations. EVALED evaporators are a technological solution which allow to exploit the biogas cogeneration for the full or partial power supply of the plant within the limits of the environmental regulations and to reduce the relevant costs for thermal energy and leachate disposal.

  • 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 new environmental legislation being introduced, worldwide, to protect the natural environment, toxin discharge is now a serious concern for treatment plant managers.

  • 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 tested against the activated sludge of the receiving works, using the Respiration Inhibition Test or the Nitrification Inhibition Test.

  • 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 can again be managed using the Strathtox Respirometer. An alternative approach is to undertake toxicity reduction procedures, such as neutralisation or acid hydrolysis, in pilot-scale laboratory studies. The Respiration or the Nitrification Inhibition Test may be used for this. In the future, toxicity reduction may be stipulated by local authority, water company or publicly-owned treatment works prior to giving discharge consents. Toxicity reduction may be evaluated using toxicity tests on activated sludge provided by the treatment works.
