  • 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.

    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

    The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

    Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

    At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

    Contaminated Water Filtration

    Industry standard best practices are designed to ensure that all work done on Asbestos Abatement Projects is done to the highest level of safety and risk management. Containment of the generated waste water fibers and debris is critical to proper compliance and worker safety. If these fibers are not captured and contained, they can be very harmful for the environment, on-site workers and the occupants of neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. Water from showers at Asbestos Abatement sites is often contaminated with asbestos fibers from washing protective gear and equipment. This water must be filtered prior to discharge into a drain.

  • 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.

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

  • Continuous Monitoring of Nitrates and Other Water Quality Parameters

    Nitrate is one of the most important parameters in assessing surface and ground water quality. Nitrates are naturally present in surface and ground waters in low concentrations, but are harmful to humans and livestock and cause aquatic ecosystem degradation in high concentrations. Nitrates enter the environment as human-induced pollution from a variety of sources, but the largest source is from agricultural fertilizer runoff . Other sources include wastewater treatment discharge, septic systems, and from pet waste. Nitrate is highly soluble in water and therefore readily leaches into water sources, whereas other human associated pollutants, such as phosphates and ammonia, are not transported as easily. This ability to be quickly transported into ground and natural waters such as drinking water wells, aquifers, reservoirs, lakes, and streams, coupled with its health and environmental implications make nitrate pollution and monitoring of major concern.

  • APHA Color #3020

    Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.
