Water and Health

(The quality of water is closely related to our health)

     Water is the source of life. Life originated from water, which is essential for all cells and living tissuesComposition is the important material basis for all life in nature. All kinds of physiological functions of human beings are carried out or realized with the participation of water. A man can go a day without food, but not a day without water.A person's longevity and health are closely related to the quality of their daily drinking water and their drinking habits.    

     Drinking water quality standards and human health-pHBased on the actual water supply conditions in various regions of our country over the years, its upper limit is rarely exceeded8.5Therefore, the standard limit range is6.5～8.5. Drinking water quality standards and human Health - Iron Iron is widely distributed in nature and is commonly present in natural water. An increase in iron content in drinking water may come from iron pipes and various water treatment agents containing iron. Iron is an essential trace nutrient for the human body and an important component of many enzymes. The main physiological function of iron in the human body is to participate in the transportation of oxygen within the body and the process of tissue respiration. The human body's metabolism requires every day1～2mgIron, but because the body's absorption rate of iron is low, it needs to be obtained from food every day60～1l0mgOnly iron can meet the demand. Iron deficiency can lead to iron deficiency anemia. Water with a high iron content is prone to iron growth in pipes, increasing the turbidity of the water and giving it a special color, smell and taste.

     The iron content reaches0.3mg/LAt that time, the chromaticity is approximately20Degree; in0.5mg/LAt that time, the chromaticity can be greater than30Degree; in1.0mg/LAt this time, a distinct metallic taste can be felt, which makes people reluctant to drink it. It is not suitable for cooking rice or making tea, and it is easy to contaminate clothes and utensils, affecting the quality of some industrial products.

     As iron-containing water treatment agents are widely used in water treatment, as a compromise solution, the standard limit value is set as0.3mg/L. Drinking water quality standards and human health-Manganese in water comes from natural environmental pollution or industrial wastewater pollution. Manganese is a trace element that the human body needs. People take in it from their diet every dayl0mgManganese. Manganese exists in various organs of the human body and plays a role in metabolism. It is also a vitaminBThe accumulation and synthesis of vitaminsCHuman development and bone calcification, as well as the acceleration of cell oxidation. Manganese is less prone to oxidation in water and is more difficult to remove than iron during the water purification process. When there is a trace amount of manganese in water, it appears yellowish-brown. Manganese oxides can gradually deposit on the inner walls of water pipes, causing the "black water" phenomenon when water pressure fluctuates. Manganese and iron have similar effects on sensory properties and often coexist in natural water. When the concentration exceeds0.15mg/LAt this time, it can stain clothes and fixed equipment, and at higher concentrations, it can cause water to have an unpleasant smell.

    To meet the requirements of sensory traits, the standard limit values are0.1mg/L. The harm of iron and manganese pollution to drinking water sources is a problem that exists in many regions of our country. Excessive iron and manganese entering the human body can seriously endanger human health.

     There are many types of purifiers for filtering household tap water, including those with simple filtration, such as those that merely rely onPPWater purifiers with relatively low costs such as cotton, activated carbon, and compressed carbon; There are also better ones, such as passingUltrafiltration membraneA water purifier used to filter tap water to meet the basic domestic water standards for kitchens, etc. Residents with a little health awareness and financial capacity have generally started to use itROmembranePure water machines with filter cores (also known as reverse osmosis water purifiers) and ultrafiltration membrane water purifiers, water purifiers, etc.

     ROReverse osmosis water purifierThe standard configuration is5Primary filtration, namely:PPCottonGranular carbon, compressed carbonROReverse osmosis membranes, post-activated carbon (also known as smallT33)5Grade;Ultrafiltration water purifierUltrafiltration water purifiers are mainly composed of ultrafiltration membranes and supplemented by other filter elements such as activated carbon (excluding filter elements). According to the installation method, they are divided into vertical and horizontal types. Vertical ultrafiltration water purifiers consist ofPPCotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membraneT33Composition; The horizontal ultrafiltration water purifier is composed of a stainless steel shell and an internal pressure ultrafiltration membrane.KDFComposition.

 In addition, when choosing drinking water, it is advisable to select high-quality plain boiled water, purified water, mineral water, natural fruit juice and vegetable juice. If drinking tap water, it can be filtered through a filter and boiled before consumption. It is generally cooked in an iron pot. After boiling, open the lid and turn down the heat to continue cooking3~5This can help some residual chlorine and harmful substances evaporate in minutes.

       In addition, develop a good habit of drinking water. Do not drink water only when you feel thirsty. Instead, drink it in small amounts frequently. The temperature should be appropriate. The ideal temperature is18 ~ 45Degrees Celsius. Warm boiled water not only facilitates absorption but also quenches thirst more quickly. It is beneficial to the human body and helps enhance the activity of enzymes. In winter, it is advisable to drink warm water. Elderly people and children are better off drinking warm boiled water directly. The time to drink water every day should be appropriate. Drinking water on an empty stomach will directly flow through the digestive tract and be absorbed by the body. Do not drink water immediately after a full meal, as it is harmful to health.
