surface contaminant Applications

  • 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.

    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.

    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.

    Pure drinking water solutions for organic food processing industry

    You go all out to produce only the best culinary creations, so how pure is your water? Water purity can have a huge impact on the flavor, aroma, visual appearance, healthfulness and even shelf life of your foods. Many beverages such as coffee and teas can be up to 99% water, so is it any wonder that water purity makes it taste so much better? When made with our pure water, alcoholic drinks don’t have the oil slick floating on the surface. Sushi masters in Japan love how our water makes sushi rice ‘pop’ in their mouth. When you boil pasta you will notice the lack of foam in the water. Ice tea stays good for weeks instead of days. Soup not only tastes better, but it’s healthier because it’s free of the contaminants present in your tap water. This is how food is supposed to taste!

  • Solutions for the in-situ soil remediation

    For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at down gradient recovery wells or trenches.

  • Solutions for the vapor suppression

    BioSolve Pinkwater is used at major remediation and construction work-sites where excavation of contaminated soils may release noxious organic odors or hazardous VOCs. The dilute solution is sprayed directly onto newly exposed soil surfaces or stockpiles of contaminated material where volatilization is taking place. Used as an alternative to foam, Pinkwater creates a barrier that keeps vapors in the soil, allowing work to continue safely without disruption to workers or neighbors.

  • Air control for wastewater treatment aeration

    Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result, large compressors are used to force air through hundreds of air diffusion filters at the bottom of the aeration basins, providing a constant 24/7 supply of oxygen to the micro-organisms in the water.

  • Mold Control

    Controlling mold spores and bio-contaminants is a challenge for indoor gardeners that requires attention to detail and specialized equipment. An average cubic foot of air has around 100,000 mold spores. When sufficient moisture is available, mold grows. AgriAir Purifiers control and eliminate Aspergillus and many other types of spores, mildew, odors, and VOC as well as sanitize the air and hard surfaces from biological contaminants generated by organic decay during the entire growing process. AgriAir Purifiers generate ionized-hydro-peroxides, which result in a proactive method of indoor air sanitation and promote organic garden production. This purification method eliminates the need for the use of additional chemicals or biocides that generally contain toxic compounds. AgriAir products can safely be used in occupied spaces throughout the entire grow cycle all while effectively destroying mold spores and other harmful bio-contaminants.

  • Solutions for the aerobic bioremediation

    BioSolve Pinkwater is used to accelerate natural bioremediation of contaminated soil either on site through surface application or on land farms through application to biopiles. When Pinkwater solution is sprayed onto and aggressively mixed into contaminated soil, hydrocarbons come in contact with the strongly “lipophilic” (oil loving) surfactant. Mimicking the process by which bacteria make hydrocarbons digestible, the surfactants “solubilize” contaminates, pulling them into an aqueous phase. This greatly enhances “bioavailability” for naturally occurring hydrocarbon degrader bacteria. Bacteria are able to more rapidly consume the contaminating oil/fuel, thereby dramatically accelerating the biodegradation process.

  • 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.

  • Geosynthetic Lining for Highway and Civil Applications

    GCL can be used in highway and civil applications such as at airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCL in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.

  • Cooling Towers and Process Water System Cleaning Applications Using Hydrogen Peroxide

    The unique properties of hydrogen peroxide (H2O2) make it a good technology for keeping cooling loops, process water loops and heat exchangers clean from fouling that can occur due to various contaminants in the water. Hydrogen peroxide works well in removing organic fouling on surfaces through mechanical means and in specific applications through biocidal mechanisms. Hydrogen peroxide can be used in a shock treatment mode where it is fed based on a timer set-up. It can also be used occasionally at higher concentrations for maintenance cleaning purposes of fouled heat exchangers, cooling water loops and process water loops. Performing an occasional shock cleaning of a heat exchanger with hydrogen peroxide can remove buildup from surfaces and can result in improved heat transfer efficiency. By removing surface fouling, hydrogen peroxide may also improve the efficiency of other biocides such as bleach, bromine and non-oxidizers.
