  • Water treatment for water distribution systems

    As a selective oxidizing agent, chlorine dioxide possesses several chemical advantages when compared to the traditional use of chlorine in wastewater treatment. Chlorine dioxide does not hydrolyze in water, and thus it retains its biocidal activity over a broader range of pH. It is also non reactive with ammonia and most nitrogen-containing compounds, and thus effective at lower dose levels than chlorine. It also eliminates phenols, simple cyanides and sulfides by oxidation. Likewise it is effective at odor control and will oxidize sulfides. Chlorine dioxide is also effective at oxidizing iron and manganese compounds.

    Real-time Control System for Wastewater Treatment Plants

    Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

    In order to meet the operational demands of modern-day plants, a new control system was developed. Proprietary control algorithms were introduced based on a large set of data from nutrient measurements in various WWTPs. The customer`s benefits are twofold: (1) achieving optimum effuent quality and, at th same time, (2) lowering energy needs and dosing of commidity chemicals.

    Industrial solutions for cooling water contamination

    Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

    Radiation Monitoring for Medicine and Research laboratories

    Medicine and Research laboratories The medical industry uses radioactivity to explore and heal the human body. In pharmaceutical laboratories, nuclear medicine practitioners and patients alike are exposed to ionizing radiation to various extents. These internal and external doses, generated by radiotherapy, scintigraphy and sealed or unsealed sources, require special precautions. Saphymo designs and manufactures various dose monitoring solutions, ranging from individual radiation protection to process and waste control. Research labs using accelerators or reactors can also rely on Saphymo’s ability to meet safety requirements by providing highly technical, custom-made devices suitable for monitoring both very low and very high activity. The Saphymo product ranges, from Radiation Monitoring Systems developed from A-Z by Saphymo to Survey meters and dosimetry, meet medical and research requirements to the full.

  • 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.

  • Gravity Main Sulfide Odor Control with Hydrogen Peroxide

    Gravity main sewer systems include major trunk lines and the tributaries that feed them. Hydrogen sulfide (H2S) odor builds up in the collections system as the flows collect from upstream reaches and become larger, deeper and more septic (oxygen depleted) in the downstream reaches more near to the wastewater treatment plant. In general, most of the more significant hydrogen sulfide odor and corrosion control problems occur in the major trunk systems segments conveying flow to the plant. Therefore, selection of sulfide treatment for gravity systems has several options depending mainly on: Duration of control required Degree of septicity (oxygen depletion) Location of target control points or "hot spots" Location of available dosing points upstream of "hot spots" Availability of civil infrastructure and utilities Sensitivity to hazardous chemicals

  • Liquid Rock - Prevening Scale Formation from Ground Water Hardness

    Groundwater is in contact with soil and rock minerals. Significant amounts of the minerals are dissolved in the groundwater. Elevated water hardness is the result of the water interaction and partial dissolution of carbonate minerals. Scale formation is a crystallisation process. Crystals are a highly organised arrangement of molecules. The determining circumstances for a successful crystallisation event include concentration, temperature, pressure and chemical environment. Suitable conditions for the formation of a crystal require numerous factors to coincide. CALSTAT RO-30 provides crystallisation interference at a molecular level :  Excellent results are achieved at low trace quantities of product. Calstat RO-30 dosed at trace levels of 4-10 kg per million litres  Corrosion on steel surfaces is reduced or eliminated  For drinking water production with RO (reverse osmosis) systems, membrane fouling is reduced.
