Water supply Water circulation: Implications for environmental protection
Water supply Water recycling is a method characterized by the repeated use of water for technological purposes after proper treatment. The introduction of this method in industrial enterprises is of significant importance for environmental protection.
Currently, water recycling has become a popular method in many industries. This method can significantly reduce freshwater consumption and reduce the amount of wastewater released into the environment. As a result of this method, it becomes possible to reduce the load on ecosystems and restore the balance of water resources.
One of the main advantages of water recycling is the ability to reuse water that was previously used in technological processes. After proper treatment, this water can be reused for the same or similar technological purposes. This reduces freshwater consumption and reduces the amount of wastewater released into the environment.
Using water recycling also helps reduce wastewater treatment costs and reduce the amount of chemicals released into the environment. In addition, this method reduces the cost of transporting water, which is economically beneficial for industrial enterprises.
In general, water recycling can significantly reduce the negative impact of industrial enterprises on the environment. This method makes it possible to efficiently use water resources and reduce the amount of wastewater and harmful substances released into the environment. The introduction of water recycling at industrial enterprises is becoming an important step in preserving our environment and ensuring sustainable development.
Introduction:
Water recycling (WRS) is an innovative technology used in industry to ensure environmental safety and save resources. In this article we will consider the basic principles of water circulation, its advantages and disadvantages.
Description: Water circulation is a technology for replenishing water resources during gold mining. The technological scheme of the process involves the use of recycled water supply by producing water in the mine. We are talking about primary water seeping from the deposit. Only 20% of this amount is enough to produce one ton of product. Just making up for such small expenses is expensive. Therefore, it is more profitable to use the regeneration products of limestone and gypsum dissolved in mine waters. This solves the problem of completely replacing water with primary and secondary - waste water, which is sent through the mixer directly to the entrance of the “mine”. This releases carbon monoxide, a gas that is poisonous and harmful to people. It is effectively absorbed by lime. A significant problem is the formation of methane. More than a third of the total reagent is spent on its production and purification. Moisture due to it, for production reasons, seriously affects production. In mines it is collected in special wells in underground tanks. With the onset of the heating season, its reserves are significantly reduced. Then an additional reagent is introduced - table salt. It is also produced locally. From the exhaust gases, a water condenser extracts water vapor, which is supplied to our purpose, that is, for the production of secondary condensate. The advantage of this method over the currently common drilling of a well is beyond doubt: it is cheaper and more hygienic. Dry gases that are under high pressure are disposed of by combustion. At the same time, the problem of water is avoided. After all, compared to the traditional method, the problem no longer exists here. Condensation is formed directly from air in the same way as from other gases. And the emissions themselves are unsuitable for fuel. They are completely absent. Instead, only the thermal and energy effect remains. The way out of the situation is a special device. It releases accumulated carbon dioxide into the atmosphere, and sends the rest of the product further. Thus, the end result is ordinary liquid fuel. Its impurities here are only aromatic and unsaturated hydrocarbons. The latter undergo thorough filtration right in the factory. Such a product, unlike conventional liquid hydrocarbons, is subsequently consumed exclusively for production needs. Since a closed cycle is used here, the disposal of harmful emissions occurs without the participation of oxygen. Cost reduction becomes important. The latest technologies for purifying recycled water can solve this problem. Conclusion: Thus, water rotation irrigation is an economically beneficial and environmentally friendly use of water in mining
