The proportional dosing complex is used to correct the pH - acidity level
This is a very important indicator for the iron removal process. Water dosing is also performed for water disinfection. Proportional dosing increases the efficiency of the filling filters - oxidizing reagents are supplied at the inlet, for example, sodium hypochlorite, potassium permanganate, hydrogen peroxide, etc.
The dosing complex includes:
- metering pump,
- pulse water meter,
- suction and injection valves,
- container for dosing the reagent.
The water meter gives impulse signals, according to which the pump injects the reagent proportionally to the programmed value. The proportional dosing complexes are designed for proportional dosing of reagents into the system, they maintain a constant concentration.
The production of proportional dosing complexes is carried out by enterprises specializing in the manufacture of dosing equipment and dosing systems.
These are diaphragm metering pumps, metering pumps, industrial chemical metering pumps, automatic metering and control systems used in many industries, including the field of water treatment systems.
The most advanced among them invest heavily in state-of-the-art manufacturing technologies to ensure the highest quality of pumps, parts and spare parts produced. The best engineers and technologists continually develop and improve the range of controllers, pumps and automatic metering systems, thus making changes in accordance with market requirements.
The proportional dosing complex must have hygienic certificates - sanitary and epidemiological conclusions. Each such complex is tested, undergoes strict control and all the necessary tests. The principles of the best manufacturers of proportional dosing complexes are quality, price and service.
In the complex of water treatment and proportional dosing, the dosing pump is switched on from an external impulse of a pulse water meter, it is controlled by a microprocessor, has an LED display and a permanent memory. Dosing modes can be constant (on-off) and proportional. Dosing is controlled in manual or automatic modes. Dosing pumps must be of high performance.
Water purification by dosing reagents - complexes characterized by high reliability and high dosing rates - is very effective. The experience of the world's leading manufacturers was used in their creation. Thus, pumps operating at a sufficiently high frequency - up to 400 strokes / min, provide uniform dosing over a wide range of characteristics. Several models are used at once to provide a wide range of performance. After-sales service and spare parts supply with this type of operation becomes simple and guaranteed.
The good quality proportional dosing complex has a glass fiber reinforced polypropylene pump casing. A Teflon diaphragm, a uniquely designed double ball valve and no contact of elastomers with the dosing media allow the pumps to handle virtually any chemical used in water treatment systems, swimming pools, electroplating plants, etc. All pumps of proportional dosing complexes are equipped with a manual release valve, which is built into the hydraulics.
All proportional dosing complexes are tested using the most modern technologies. For their production, only high quality materials are used, which undergo a series of intensive laboratory tests and strength tests. Before the final test, each pump is loaded for six hours at maximum speed. The customer can always request a certificate of tests carried out under the conditions specified by the customer.
