process wastewater monitoring Applications

  • Process monitoring and controlling for wastewater treatment industry

    Automation can save money, optimise a process and give warning of potential breeches of discharge consent. However, instrument selection is fundamentally important if a control system is to function efficiently. The measurement device must accurately and quickly respond to process variations and it must be reliable in operation if the control system is to function as intended. Designed properly, energy and chemical use can be significantly reduced, saving money and ultimately improving effluent quality.

  • Turbidity Monitoring

    The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides turbidity as one of the parameters available within the 3 channel TriLux. For applications requiring turbidity measurements compliant to ISO07027:1999, CTG can offer the TurbiLux Nephelometer.

    Monitoring of hydrocarbons in bilge water

    Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited by national and international regulations.

  • Monitoring of Algae in Drinking Water

    The UniLux in-situ fluorometer can be configured to detect a number of key parameters that are of importance to the Water Supply Industry. Primarily, the detection of Chlorophyll a in stored water systems, such as reservoirs, assists in the planning and informs decisions on water abstraction in relation to natural algae blooms that regularly occur throughout the year. As well as Chlorophyll a, these in-situ fluorometers can detect cyanobacterias, such as Phycocyanin and Phycoerythrin, which are often associated with algae groups of a toxic nature. Knowledge of concentrations of algae within the water can assist in determining the loading into water processing plants.

    These in-situ fluorometers are available as single parameter sensors (UniLux), or 3 channel sensors (TriLux).The CTG FastFlow fast repetition rate fluorometer provides information on the physiological state of algae it monitors. As well as providing detailed information on the growth rate of the algae (which can indicate the occurrence of a future algae bloom), it can immediately inform and alarm on toxins that have accidentally or deliberately been introduced into the water systems, as with the FastGuard system. The FastFlow differs from the FastGuard system in that it logs and displays detailed information on the state of the algae monitored for operational requirements.

    Online Monitoring for the Demi-Water Production Industry

    Demineralization is the process of removing mineral salts as well as organic impurities from water by means of ion-exchange and can be found in various industries such as the chemical, food & beverage, irrigation and filtration industries. The consuming side of the industry relies on ever increasing quality and availability of demi-water while the manufacturers have to balance cost/output. AppliTek provides high quality analytical tools to increase process efficiency and quality control. Continuous measurements with high accuracy are carried out on the critical QC/QA parameters of the deionizing process:

  • Gas analysis & monitoring systems for water - natural sciences

    In nature, the chemical elements can be represented by more isotopes, or atoms of the same element, characterized by a different number of neutrons in the nucleus. When the proton / neutron ratio does not exceed that value likely to upset the balance of the atom, resulting in the phenomenon known as stabilization of radioactive decay, the isotope is called stable. That is, over time, will not tend to emit energy and sub-nuclear particles to gain energy stability, giving rise, at the end of the process, the daughter nucleus (a different element, characterized by stability energy).

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.

  • Water measurement systems & sensors for water quality monitoring

    Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment.  Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.  Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.

  • Gas detection analyzers for wastewater treatment industry

    Regulations prohibit facilities from discharging flammable or explosive wastes from their processes into the wastewater collection system. These wastes are not only a fire and explosion hazard but they can also effect the efficient and effective operation of the treatment facility. PrevEx Flammability analyzers are used to continuously monitor the waste stream for flammable gases and vapors. Their unique design and operating technology make them the ideal analyzers for the harsh conditions found in the sewer environment.

  • Water Contamination Detection

    Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is a common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste. The CTG FastGuard fast repetition rate fluorometer analyses information on the physiological state of the algae it monitors within an in-line flow system. A number of key parameters are monitored and analysed by the on-board embedded software, which instantly initiates both an audible and visual alarm on detection of a contaminant within the water system. The FastGuard is a robust low maintenance system which avoids false positives often provided by other contamination detection systems.

    Pure Water and Highly Purified Water

    Pure water and highly purified water are crucial factors to production in numerous processes and industries and can be used as a raw material, auxiliary and/or for process operation. It is very important to pay particular attention to the quality of the water used as it is crucial to product quality and the safe operation of the production facilities. Therefore, continuous monitoring is essential - from an ecological as well as an economic point of view.
