  • Nitrogen Generator for Laser Welding

    Whether you’re welding stainless steel, carbon steels, titanium, or aluminum, you need a high quality weld with a small heat-affected zone as well as high cooling and heating rates, and that’s where our laser welding nitrogen generator comes in. At Gas Control Systems, we’ve got the right nitrogen generator for you. Maintaining the proper weld temperature is important when you need to join multiple pieces of metal. At Gas Control Systems, we can provide you with the right laser welding nitrogen generator that will help keep those temperature at the correct level as well as remove both moisture and oxygen from the beam path.

    Water Treatment Solutions for Nitrate Removal

    Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled over 112 million pounds from 1991 through 1993.

  • PLAZKAT systems for treatment (removal, neutralisation) of smelly substances from the air

    PLAZKAT Aero units are used to neutralize bad smells from waste treatment facilities, caused by the presence of sulfur and nitrogen compounds - hydrogen sulfide, mercaptans, and ammonia. Urban waste treatment facilities, local waste treatment systems in factories, pumping stations in waste water treatment systems are characterized by a strong smell of sulfur and nitric compounds.

    Carbon capture and storage (CCS) applications

    Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.

  • Wastewater Treatment for Aquaculture

    Wastewater treatment for aquaculture will typically consist of processes for removal of major pollutants such as organic matter, suspended solids, ammonia nitrogen, dissolved gases and bacteria/virus. Typical unit processes may include: Biological treatment Solids removal Disinfection

    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.

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.
