    Odor control for wastewater treatment processes

    Natural odor control for wastewater treatment processes. Industrial and municipal wastewater treatment generates odors that can be strong, persistent, and a nuisance to employees, residents, businesses, and industries located near the wastewater treatment plant.

  • Process monitoring and controlling for wastewater treatment industry

    Automation can save money, optimise a process and give warning of potential breeches of discharge consent. However, instrument selection is fundamentally important if a control system is to function efficiently. The measurement device must accurately and quickly respond to process variations and it must be reliable in operation if the control system is to function as intended. Designed properly, energy and chemical use can be significantly reduced, saving money and ultimately improving effluent quality.

  • 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.

  • Energy reduction and coagulation process control for wastewater treatment industry

    One of the biggest costs for water-water treatment is energy consumption; the cost of which is likely to escalate with increased demand. Ineffective process control may not only be costly but environmentally impacts though the inefficient use of an un-renewable resource. Furthermore, poor process control in one area may also impinge on neighbouring processes ultimately affecting effluent water quality.

  • 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.

  • Waste water respirometry solutions for process optimisation

    Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the bacterial cell walls ceases and therefore biodegradation is significantly compromised.

  • algae control in drinking water plants

    By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the demand of chemicals or filtration and in turn creating problems with THM (trihalomethane) formation. Other common issues are growth of toxin and geosmin producing cyanobacteria (blue-green algae) within the intake reservoir or dam. These molecules give the water an unpleasant `earthy ` taste.

    Environmental Control for the Water Utility Industry

    This section contains applications relevant for compliance, water treatment, drinking water and natural sources.

    Collecting, treating and distributing water to consumers and industry, in compliance with quality standards, means a challenging task to water companies. Both private as public water treatment entities have to manage carefully and sustainably their sources, processes and even distribution networks. AppliTek supports them not only with an extended portfolio of analyzers but also with its experience in the advice, design and construction of complete monitoring systems and stations.

  • 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.

    Ozone Water Treatment for Odor Control Industry

    Odor from industries is a growing problem as cities are expanding closer to industrial areas. The production at food processing industries, fish factories, biodiesel plants and the like can create odors that might be a nuisance to the surrounding area. Odor control systems has thus become important to industries located closed to urban areas.

  • Erosion & sediment control solutions for water remediation

    `Water should never be treated as a nonrenewable resource; it should always be treated with the respect it deserves as the foundation of life on the planet.` Most water on earth is in a continuous cycle between water bodies, land and the atmosphere. An important component of smart water solutions is the cycling of water treatment solutions using processes by which water enters, moves through and exits soil are essential for sustaining plants and soil organisms, transporting nutrients and recharging surface and ground water supplies. Water moving in soil also impacts the behavior and transport of soil solutes and their effect on water quality.

    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.

    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.
