Water tank is the main and most convenient method of storing, accumulating and dispensing potable and technical water supplies. It is used in many areas of human activity that require the storage and storage of liquids.
These containers are widely used in the everyday life of the population. They are also used in food, agricultural, chemical, pharmaceutical and other industries.
Application
Different industries require the appropriate amount of water of a certain quality. For example, a tank with water intended for consumption must comply with sanitary requirements and regulatory documents that establish the necessary parameters.
Depending on the scope and volume of the enterprise, the water tank is installed both above the ground - on the ground surface or on a steel or concrete base, and below it - by digging into the soil. Water containers are used for the following purposes:
- water collection and storage;
- fire fighting and other emergencies;
- preservation of technical or drinking water supplies;
- organization of wastewater systems;
- creation of complexes for wastewater treatment.
Classification
Capacities are classified by type, shape, volume and body material. By type, a water storage tank can be horizontal or vertical, in shape - cylindrical or rectangular. It can be made from both metal and polymers. Any material has its advantages and disadvantages.
Types of containers
Horizontal tank is widely used in many industries. It happens depending on the purpose of various geometric shapes: rectangular, cylindrical or oval. The most economical option is a rectangle-shaped container, since the manufacture does not require rolling sheets, and its assembly is less laborious.
Vertical tank is a very popular option. It is a cylinder with a conical or flat bottom, floating or straight roof. The vertical water tank is made of reinforced concrete with appropriate waterproofing, stainless steel, insulated with a heat insulator, and polymeric materials. This type is more expensive to produce than a horizontal tank, but it can withstand more pressure and can be installed on a relatively small area of land.
Plastic tanks
Plastic containers are made from industrial grade polypropylene or polyethylene that can hold food. Thanks to this, they cancontain not only technical water, but also drinking water. Plastic water tanks differ in structure and shape depending on the application.
Tanks storing drinking water are usually made in blue and are marked with a special mark. They do not transmit ultraviolet rays and are absolutely harmless, therefore they do not add any taste or smell to water even during long-term storage. Any plastic containers are airtight and resistant to many environmental influences. They have a long service life (about 50 years with proper use) and do not require repairs or painting. Plastic tanks are steady on any surfaces. They have a number of advantages over metal counterparts, these are:
- convenient transportation;
- light weight;
- low cost;
- resistance to external factors;
- sustainable material.
Plastic containers are widely used in production, watering in summer cottages, washing squares or streets, storing water in baths, extinguishing fires and for other household purposes.
Fire tanks
Fire water tanks are used to create a supply of a certain volume of water, which, if necessary, will be used in order to eliminate fires. These technical water tanks are independent of the water supply system, therefore they are indispensable for enterprises that do not have access to a water source. Some types are made with a partition, which makes it possible whenscheduled inspection or maintenance, do not disconnect the enterprise from the fire extinguishing system. Also, containers with two sections are used when mixing two types of liquid, which eliminates fire more effectively.
Fire tanks can be of different models, which allows you to choose the best option for the fire system of any enterprise. An organization with a small area with the help of an underground reservoir has the ability to effectively use the ground area and significantly reduce water losses from the evaporation process. Another popular option is the ground installation of the tank on props at a height of 3 m to 7 m. With this arrangement, the liquid is supplied without the use of an electric pump, which is very important in case of fire during a power outage. If an option for installation inside a production facility is required, then a rectangular tank will be an excellent solution, which can be used simultaneously as a storage of fire water and process water.
Fire water tank is made of ordinary or stainless steel, as well as plastic. Steel vaults have a long service life, on average at least 10 years, and are used at temperatures from -60 °C to +35 °C. However, a container made of ordinary steel has a lower price than one made of technical stainless steel, but after a certain time it requires scheduled repairs and mandatory external and internal painting. It is galvanized to protect the body.
Washing machine with water tank
Automatic washing machines today are indispensable in every home, but they need a constant supply of water to function. If there is no centralized water supply, for example in rural areas, or there are interruptions in water supply, as well as low pressure on the top floor of an old high-rise building, then connecting it can be difficult.
The solution to this problem is a water tank. The washing machine will be provided with the necessary pressure at the inlet, thanks to the storage tank, into which water can be poured by any means: from the water supply system, from a well using a pump, buckets from a imported tank and in other ways. In rural houses, the tank is usually installed in the attic or at a height of at least three meters.
Some manufacturers of washing machines produce ready-made models with a water tank. They come with both automatic filling of water from a common system, which will be an excellent solution for apartments with problematic water supply, and manual filling in the absence of water. The latter are more suitable for rural houses without running water.
