Surface Contaminants Applications

    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.

    Wastewater technology for the oil exploration and refinery

    In the secondary recovery stage of an oil reservoir, process water plays a central role, just as in the extraction of natural gas. After the oil exploration, the produced water must be separated from the oil and gas. The process water needs to be prepared in order to be re-injected into the water cycle of production. For this purpose, highly efficient separation methods are required.

  • Microbial testing for personal care products sector

    The Problem: Microorganisms. personalcareMicrobiological contamination is a threat to product quality and process integrity in the personal care products and life sciences manufacturing industries – the purity of raw materials including water is essential to ensure manufacturing compliance. Microorganisms may be introduced at several stages of the process; subsequently, manufacturers must put in place stringent Quality Assurance / Quality Control (QA/QC) programs to manage microbiological contamination.

  • 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.

  • Bio-Contaminant Control

    Microbes and bio-contaminants are pollutants such as bacteria, germs, and virus. All are small in size and usually microscopic, yet they have an amazing ability to do damage to all living organisms including plants and humans. When dealing with medical-grade and food products it is important to maintain the highest levels of sanitation possible. Many everyday illnesses are caused by viruses like the common cold or the flu. AgriAir purifiers will destroy 99.99% of airborne and surface bio-contamination helping to protect potentially vulnerable patients from dangerous microbes. In this new era of exponentially expanding plant pathogens affecting indoor crops, Hydroperoxide generators built into the AgriAir system are the answer to concerns that the airborne environment stays as sterile as possible. IHP technology destroys microbes, pathogens, and virus by changing their molecular structure and rendering them harmless.

  • 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.

  • Monitoring surface water for wastewater treatment industry

    Pollution Risk: Surface water encompasses storm water derived from hard standing areas, river water and reservoirs. All types of surface water are at risk from ingress of pollution and therefore need to be monitored. On-line continuous monitoring can identify and alarm pollution so corrective action can be taken
