Wagner-D dosing stations
Reagent dosing is used at industrial enterprises, in the housing and utilities sector, in sports and recreation complexes for CVP of swimming pools, as well as for private homes.
Dosing of reagents is a critical stage of water treatment, depends to a large extent not only on the degree of water purification, but also on the cost-effectiveness of the technology.
Water treatment invariably requires the dosing of one chemical or another. For drinking water treatment, chemicals such as hypochloride, coagulant, etc. need to be dosed in very precise quantities.

1. Purpose of reagent dosing plants
Water treatment is an obligatory and important process. The whole point is that initially it contains an increased concentration of various impurities. Pure and usable water in the original source does not exist. All to blame for the ecology and human activity. Various harmful elements are absorbed into the soil and then get into the groundwater. Sewage discharges that have not been pre-treated pollute surface water bodies. Old pipes, add different impurities to the flow. That is, any water requires filtration. It may contain minor or not so dangerous substances as well as toxic ones. There are many methods of filtration and some of them involve the addition of chemicals. Sometimes chemicals are used to enhance a process or to increase the speed of a reaction.
You can't just add chemicals to the water like that. First, the composition of the water and the concentration of impurities is determined. Next, chemicals for purification are selected. Then the dosage for a certain volume of water is calculated. In order to add these chemicals, special equipment is installed. We are talking about dosing units. This is a complex that contains sensors, a control unit and a pump-dosing unit. Completion of installations can be different.
The main task of such devices is to add chemicals to the water flow. Some installations are able to make a concentrate before use. Dosing units are necessary when the water treatment system includes a filtration cycle with the help of reagents. This can be any industrial enterprises, agricultural farms. Very often chemicals are used in the treatment of wastewater.
The installation of such systems has a lot of advantages. First, the presence of a person is excluded. After all, in order to work with aggressive substances requires compliance with safety regulations. And since most reagents are quite aggressive, it is desirable to automate this process. Secondly, the supply of substances must be strictly dosed. Otherwise, new elements may appear in the course of chemical reactions. And if you add few reagents, filtration will remain incomplete. For example, in industrial production, water is treated constantly and consumed in large volumes. Manually adding reagents is simply inexpedient. Therefore, it is easier to install special equipment.
If the reagent dosing unit is used to supply chemicals immediately into the stream, it extends the service life of the pipeline. Cleaning takes place immediately and no scale remains in the pipes. This preserves filtration efficiency and prevents early replacement of equipment due to wear and tear.
Reagent dosing units are often used in the cleaning of swimming pools. Since it is required to filter a large volume of water continuously, in a short period of time. Usually chlorine or its analogs are used. In any case, the substance is very caustic and aggressive. And its addition must be strictly rationed. Therefore, dosing units will help to quickly disinfect water without using additional equipment. Sensors allow you to monitor the flow of reagents and possible changes in the composition of water. If there are discrepancies, the program is changed.

2. Standard filling
Reagent dosing units can be filled in different ways. This depends on the capacity and the intended use. In a standard filling, the system contains a chemical tank, a metering pump, meters and a control unit.
The tank is necessary to put reagents into it. It can be a concentrate or a ready-made solution. The pump is needed to add chemicals to the water in a certain volume. There are several types with adjustable or proportional dosing. In the first case, the volume of chemicals depends on the current state of the water. That is, the concentration and presence of impurities, acid-alkaline balance and other technical characteristics. The system calculates the required amount of chemicals and delivers them using a doser. This is very helpful in reducing the consumption of reagents. In the second case, the concentrate is fed according to a set program, when the system has the maximum volume of water. The control unit allows you to automate the operation of the installation. It is with its help that the program is recorded, according to which the addition of reagents will take place. In addition, with the help of sensors, you can monitor the composition of water.
The equipment of the device can be supplemented with sensors to monitor the state of the flow. In addition, the system can be modernized by replacing the control unit with a newer or more advanced functions. Such installations can be used even in domestic conditions. However, it is not recommended to treat drinking water with reagents. Therefore, most often the systems are implemented in the process of industrial water treatment in the filtration of process water or waste water.
3. Advantages of the units
Dosing plants have many advantages. These include, of course, the automation of the process. Which is especially relevant in industrial production. In addition, they allow you to control and adjust the composition of the water. With a regulated supply, it is possible to reduce the consumption of reagents.
Dosing units can be used with any purification methods. They are made of quality materials. This is necessary in order to withstand the aggressive effects of chemicals. After all, for filtration can be used chlorine, hypochlorite and other substances that are quite harmful.
Service maintenance is practically not required. It is enough to adjust the dosing programs and inspect for external damage. Any special conditions for maintenance are not required.
When installing such equipment, the quality of treated water is significantly improved. Reagents are able to remove those elements that can not clean reagentless filters. Also contribute to the speed of reaction, which affects the performance. Reducing filtration time is very important when treating a large volume of water. As for the volume, reagents can work both at high loading and at minimum loading.
Compliance is also a prerequisite for any water treatment. Dosing units allow you to comply with the regulations, through the precise addition of reagents. This means that the water composition will be optimal, with the appropriate acid-alkaline balance and organoleptic properties. This is very important for process water or for filtration in swimming pools.
4. Conclusions
Modern dosing units are very versatile in terms of equipment and scope of application. They are the optimal complement to an existing water treatment system. Thanks to them, the process is fully automated and under control. It is possible to choose different feed options, depends on the equipment. Such devices can be installed in both new and existing water treatment systems. There are no special technical nuances in the installation. But still, given the specificity of the equipment, it is desirable that the installation is engaged in professionals. Especially since most often such installations are needed in industrial spheres.
Such devices help to simplify the process of water treatment when using reagents. As for the economic part, in this case, dosing units help to reduce the cost of reagents. Special maintenance is not required.
When choosing equipment should be guided by performance and place of use. It is also necessary to take into account nuances. For example, the choice of pump type or reagent supply. If there are difficulties in the selection, you should contact specialists.
