High-quality water treatment of boiler plants is one of the prerequisites for reliable and high performance operation of equipment in thermal power generation. It is up to the quality of this technological phase depends directly on the technical condition of the thermal system. When violations of water-chemical regime on the steam boiler plant may be damaged. In this regard, water boiler becomes one of the essential areas of work for any company working in this industry.
Typically, water is pumped from public (artesian) or sources of municipal water pipes. When using the steam boiler water from underground sources in the majority of cases, there is a need for neutralization of high iron content, therefore, the most effective technologies to combat such composition of water is considered to be the use of steam boilers for water reverse osmosis systems, They allow you to remove iron, bringing its concentration in the water almost to zero.
Because of the expense associated with treating serious burns, the long Beyond training, the best way to prevent power boiler accidents is through types – power boilers, steam heating boilers and water heating boilers – are a carbon monoxide detector for the control room and/or boiler room area…. read more
Water boiler should be carried out using the boot materials catalytic (capable to accelerate the oxidation process and increase the depth of process water actions or inert materials. Among the catalytic weekly when water for boilers often use MTM, MGS, FILES by HAND, and among the inert-quartz sand, anthracite or, for example, Sorbent-AL/Ms.
In any case water boiler installations must be done using the faction materials and filters-have a special slit drainage, which will prevent the stem material in the washing process.
Water boiler in most cases also does not do and without having to reduce the water hardness. When working with steam boilers uses the sodium or membrane desalting. The process of softening occurs in two steps (the residual hardness should not exceed 0.01 mg EQ/l). If we are talking about a small boiler installation with counter-flow regeneration will be ineffective. They will get a good softening in one step, but this will require pretreatment of high performance level. In the practice of our company the most highly efficient combined method has shown himself water for boilers based on primary application of reverse osmosis or nanofiltration series iceberg and subsequent flow transmission through secondary filters-based ion-exchange water softeners (sodium-cation exchange). It is precisely in this building complex water treatment for boilers is achieved and the highest quality of feed water and maximum reliability with protection from penetration hardness salts, and low operating costs. When this interval blowdown vessels and routine maintenance intervals of boilers is increased tenfold. National Center for water technology engineers have calculated that water treatment system based on our technology, have economic efficiency is several times larger than classic methods of preparation of feedwater boilers and steam generators.
Water boiler with water from the municipal water-pipe fence, generally do not require pre-treatment, but mandatory control of chlorine. Permissible concentration, from which water can be made to install the softener is 1 mg/l of such a figure is a rarity in the centralized water supply systems, so dechlorination in most cases is not required. The only exceptions are reverse osmosis when using them runs full dechlorination using activated charcoal.
Industrial water treatment
Chemical water treatment system is a system of hardware and complex technological solutions that require professional and neat design in accordance with the rules and requirements for water quality, which operate in a particular industry.
When such projects must take into account that industrial water treatment is an activity related to special requirements with respect to all phases of the work, including the drafting of a system, its embodiment, selection and installation of equipment, construction of sewage treatment plants, timely maintenance, if necessary, replacement of filtering elements.
Natural underground or ground water sources, that would be different requirements for full compliance of the industry requirements for the moment simply does not exist. It is therefore only natural that industrial water treatment is needed in all enterprises where the water is used as a basic resources, as well as in the area of housing.
Depending on the purpose and scope of future water use choose and method of performing this task. Inherently water-the combination of physical and chemical water treatment methods that allow you to bring water to the desired quality for future use.
Water treatment basic techniques
There is an impressive amount of processing methods and technologies for industrial water purification. Each such method-its function and scope, clearly outlined the technical capacity of the water treatment technologies. Water aeration. This process represents the oxygen saturation of water how to oxidize in it elements-for example, organic compounds, iron, manganese, hydrogen sulfide and carbon dioxide and activation of the catalytic abilities are used later in the process chain grainy weekly. This same technology water treatment applied to the biological treatment of wastewater, in order to ensure the possibility of vital activity of aerobic micro-organisms involved in the process.
Aeration is both water where occurs on special water blowing method no separate gearbox filed air and pressure where there is saturation of water with oxygen. Both methods have their own specifics aeration application depending on the composition of the source water and scope of technology. Water treatment using Prefilters and microfilters used most often in heating systems. Only in this way it becomes possible to create the conditions for protection of the equipment from the abrasive effects of solid particles in the water, as well as deposits, deteriorating the work units and causing them damage. water purification is to reduce its hardness (magnesium and calcium ion concentration). More often than not allowed water hardness in the system at the level of -1.5 1.0 MEQ/l in accordance with international requirements for the operation of household appliances and industrial equipment. Respecting these norms will not sediment. This industrial water-softening as a mandatory step in water treatment technologies in metallurgy, perfumery, pharmaceutical, food and petrochemical industries.
Ozonation of water can be attributed to the highly effective modern methods that use for water treatment of ozone-treated water saturation. Under the influence of ozone-air mixture all dissolved impurities are moving into hard physical phase and fall out. With the subsequent mechanical filtering filter fine purification filter or filters with granular, it is completely removed. Once in the reactor tank oxidation process of sewage treatment plants, the remainder of the ozone is removed on special techniques ecology therefore, destructors, becoming one of the defining factors in favor of this processing technology. the permanent development of systems for water purification, has been designing wastewater treatment plant, providing a full spectrum of necessary documentation for these purposes and equipment. We offer a wide choice of various types of equipment and different methods, on the basis of which can be made water purification of almost any complexity. Depending on the features of technological process system of water treatment and construction of sewage treatment plants could be solved also in accordance with individual needs, on the basis of the existing specific enterprises.
