process water chlorination Applications

  • Chlorine dioxide for industrial water treatment

    Chlorine dioxide is used as a biocide in many industrial water treatment applications including cooling towers, process water and mill water.  Its selective oxidative properties usually results in lower dosages of ClO2 while also achieving improved microbial performance.

    Ultraviolet Disinfection for Process Water

    Water is often used as a product, or as part of the manufacturing process. In many industrial applications, processes are chemical (chlorine) intolerant, and UV is widely adopted. atg UV Technology engineers will be pleased to discuss solving disinfection problems with you. As well as a powerful disinfectant, UV is used to remove chlorine, chloramines, ozone, bromine, and a wide variety of contaminants from industrial process water. Within micro-electronics facilities for example, UV is used to remove Total Organic Carbon (TOC) from ultra pure rinse water.

  • Water treatment for food processing

    Most food processing facilities currently use a combination of different chemicals for all surface and machine disinfection. They periodically rotate the use of different sanitizers to prevent the harmful microorganisms from building a resistance to their killing properties. Unfortunately facilities are still experiencing pathogen outbreaks. Chlorine dioxide’s unique killing ability does not allow for the build up of resistance or mutation, and therefore eliminates the need for all of the other chemicals. Chlorine dioxide is effective for use in controlling microbiological growth in flume waters and other food processing water systems such as chill water systems and hydrocoolers.

  • Water treatment for meat processing

    Water is one of the single biggest raw materials used in meat processing, and its quality is of great importance to prevent contamination of food product. The use of contaminated water in the processing plant can spread infection across the whole food batch. This is a cause of serious concern to the food industry, consumers and regulatory bodies, besides that, it causes financial losses and food scare. Chlorine dioxide, a very powerful biocide, has a number of advantages over other products commonly used in the meat processing industry. When properly applied, chlorine dioxide can act as a break in contamination thereby reducing/eliminating cross contamination as well as removing superficial microorganisms before they have an opportunity to become attached and penetrate the carcass.

    Hazardous waste treatment solutions for chlorine industry

    The mercury cell process is a formerly widely-used production technique for the production of chlorine and caustic soda. The liquid metal, mercury, acts as cathode (negative pole) in this process. In the past, the loss of mercury during the process (to air, soil and water) led to serious health and environmental problems. Therefore, most European chlorine producers have decided to phase out the mercury cell process by 2020. Nevertheless, even today, almost 6000 tons of mercury is used per year for chlorine production in Europe alone. As a result of this, yearly waste outputs contain around 1200 tons of mercury, which are stored on-site or sent off for disposal.

  • Water Disinfection for Municipal Water Treatment

    As one of the world`s most precious natural resources, the reuse of water is becoming increasingly important. MIOX is both the most cost-effective solution and the preferred technology for disinfection and oxidation of wastewater for reuse or reintroduction into the environment. MIOX`s hypochlorite generators offer a safer, technologically superior solution to wastewater treatment, virtually eliminating many of the negative problems associated with traditional chlorine disinfection. Safer, economical and significantly more effective, MIOX is revolutionizing the process of making water safe again.

    Algae control

    Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. By blocking sunlight within water treatment tanks, you can stop algae growth, reduce chemical usage, and minimize the formation of disinfectant by-products (DBPs). Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.

  • Odor Scrubbers Applications with Hydrogen Peroxide

    Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine, create additional environmental problems. Consequently, there is a growing need for alternative, non-chlorine methods for destroying cyanides. Peroxygen compounds such as hydrogen peroxide, peroxymonosulfuric acid (1), and persulfates (1) are effective alternatives to alkaline chlorination for destroying free and complexed cyanides. The choice of peroxygen system depends on the reaction time available, the desired products (cyanate, or CO2 and NH3), the types of cyanides being treated (free, weak acid dissociable, or inert), and the system economics. Treatment with Hydrogen Peroxide While hydrogen peroxide will oxidize free cyanide, it is common to catalyze the reaction with a transition metal such as soluble copper, vanadium, tungsten or silver in concentrations of 5 to 50 mg/L (2).

  • Water treatment for breweries

    A brewery process presents one of the biggest challenges possible to a microbiological control program. Microorganisms are responsible for both the production and the degradation of the product. Microbial control is also critical for production and filling equipment. A brewing environment offers various applications where chlorine dioxide may be employed, like as terminal sanitizing rinse in the CIP systems or sanitizer for pasteurizers or filler head assemblies.

    Drinking water solutions for the TOC removal efficiency

    Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.
