    Monitoring of raw water intake

    The Situation:

    Hydrocarbons in municipal water supplies,  including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through undetected. Desalination systems using reverse osmosis (RO) membranes can be irreversibly damaged by the presence of hydrocarbons. Continuous monitoring of water source intakes can prevent system contamination and subsequent damage.  Accurate, low maintenance monitoring systems such as the TD-4100 XD and XDC have been protecting water intakes worldwide for over 20 years.

    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

    The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

    Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

    At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

  • Water treatment systems for chemical industry

    The effluents that accrue in the cleaning process of silo vehicles and containers for transportation of raw materials for the chemical industry, are highly complex and constantly changing in the composition of wastewater. Flocculation as the prior art of treatment for chemical waste water can not remove many of the completely dissolved invisible substances. Thus, the residual stresses are evident despite high claritv of the `Treated effluent` is often well above the levels witch are applicable for wastewater in domestic environments.

  • 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.

  • Wastewater treatment for the sea- and inland ports/terminals

    Facing the increasing oversea trade, the environmental protection of the oceans is becoming increasingly important. The motto of the International Maritime Organization of the United Nations in London (IMO), “Safe, secure and efficient shipping on clean oceans” confronts the shipping industry and in particular the terminal ports with growing challenges. The stored fuels, raw materials and resources of a country must not pollute the harbor water with their emissions in case of rain. Produced liquid ship waste contains oil emulsion and saline bilge water among others.

  • Water treatment research for pulp and paper industry

    Historically the pulp and paper industry has had little need for desalination and reuse – not least because the majority of production is located near water sources. Four things are changing this state of affairs: The move towards recycling means that production in mills located in “urban forest” areas is rising. These facilities face higher water costs than green forest located mills, and have a greater interest in water efficiency. The fastest growing market for pulp and paper is in China, where raw water sources are both limited and impaired, and water technologies which can address these challenges are at a premium.

  • Wastewater Treatment for the Bioenergy Industry

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

    The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

    Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.

  • Drinking water solutions for the coagulation optimization

    Problem: Drinking water plants that use surface water or ground water under the influence of surface water are susceptible to high levels of organic matter in the raw water. Reduction of organic matter through coagulation/sedimentation and filtration is important to lower the potential for disinfection by-product formation (DBP) and limit operational problems. In addition, organics in water consume the polymers used for the coagulation process, which reduces the efficiency of the treatment. Therefore, optimization of the polymer dosing heavily depends on the concentration of organics.
