    Monitoring solutions for the opacity and dust monitoring

    There is a requirement for many small boiler operators to monitor Opacity to determine the smoke density emitted from the boiler. On small boilers we recommend the DCEM 1001 Opacity monitor; this simple, low cost monitor   has high efficiency air purges use compressed air to ensure that optical surfaces are virtually free of dust or debris contamination. This ensures minimal maintenance is required on the sensors.

    Monitoring of raw water intake

    The Situation:

    Hydrocarbons in municipal water supplies,  including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through undetected. Desalination systems using reverse osmosis (RO) membranes can be irreversibly damaged by the presence of hydrocarbons. Continuous monitoring of water source intakes can prevent system contamination and subsequent damage.  Accurate, low maintenance monitoring systems such as the TD-4100 XD and XDC have been protecting water intakes worldwide for over 20 years.

    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

  • Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

  • Groundwater Monitoring for Construction Sites

    All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and flood in a shorter time, but also to dry up sooner. These conditions cause great difficulties for subsistence farmers in developing countries. Urbanisation also causes faster run off because of the non permeable surfaces such as roads, roofs and car parks. This also creates drainage problems that can lead to contamination and erosion of natural water courses.

  • Radiation Worker Training

    Safe Training Systems (STS) are specialists in the provision of high quality, highly realistic simulated radiation monitors. STS have sold instruments for training to over 12 different countries across the world the majority of which have been used for Nuclear Worker training. The simulation system uses completely safe methods to recreate radiation fields and contaminated surfaces, this means that novice users can be taught basic principles without any exposure. There are of course also benefits to the trainer who again does not accumulate any dose and can therefore carry out more sessions. Instruments for workers vary widely from the Thermo Electra, RO2/20 and FH40G through to Ludlum model 3s and Automess 6150AD. With a wide range of instruments and sources there is always a solution to fit both budget and purpose - please contact sales@safetrainingsystems.com for more information.
