  • Water treatment for cooling towers

    Controlling and preventing the growth of microorganisms in a cooling tower is extremely important and required to keep the system running at optimal levels. The presence of microorganisms will cause the system to breakdown and decreases the efficiency of the heat transfer. Typically oxidizing biocides such as chlorine and bromine have been used to treat cooling water. Unfortunately these chemicals are highly reactive with other chemicals and microbiological species found in the water. Chlorine dioxide however is very non-reactive to other compounds found in the water and retains biocidal efficacy. Likewise it is also a superior chemical for removing the biofilm, which leads to the most predominant problems that all cooling towers face.

  • Industrial water softening

    The presence of certain metal ions in water causes a variety of problems. These ions interfere with the action of soaps, lead to build up of limescale, which can foul plumbing, boilers, heating equipment. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water extends the lifetime of plumbing and heating equipment. Softening of low TDS ( Total Dissolved Solids ) water is done commonly with a Strong Acid Cation ( SAC ) exchange resin operating in the sodium form and regenerated with brine. PuriTech`s latest development is a very performant continuous ion exchanger, based on PuriTech`s innovative ION-IX technology which is based on true counter-current ion exchange.

    Chemical Water Treatment for boiler water & heating systems

    In nearly all industrial areas steam is needed for different aims e.g. steam for process side, heating purpose or the generation of electricity. To reach the best efficiency of the boiler system an optimal boiler water treatment is essential. Disturbances in boilers caused by deposits, scaling, corrosion, local overheating or carryover into the steam reduce the operating safety and could lead to tremendous economic damages. Kurita delivers innovative technologies to prevent scale and corrosion in the whole boiler system - feed water tank, boiler, steam and condensate system.

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.

  • Water treatment research for food and beverage industry

    Direct reuse of wastewater in the product is not on the menu in the food and beverage industry, but the reuse of water for other purposes (e.g. washing) is now a priority. Most major F&B companies have made commitments to reduce their water consumption per unit of product, and reuse is an important part of the strategy for achieving this. Furthermore much of the growth of the industry is in emerging markets which typically have more limited, lower quality water resources than developed countries, creating water treatment challenges. In developed markets, emerging concerns about pharmaceutical by-products and other trace contaminants making their way into the product have lead to greater use of desalination technologies on the process water side. Value from waste propositions such as energy recovery, water reuse (not within the product) and materials recovery ensure that investment in water technology benefits the bottom line.

    Waste water treatment plants Air quality control by TRS MEDOR

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated.

These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

  • Ozone Water Treatment for Activated Sludge Process Plants

    Ozone breaks up filaments and improves settling characteristics of the sludge... Filamentous sludge is a common problem at activated sludge plants. With ozonation of the return sludge flow it is possible to reduced the amount of filamentous bacteria in the sludge and significantly increased the settling properties of the sludge.This in turn means better performance of the activated sludge process. When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher quality sludge in the bioreactor, which leads to higher biogas production.
