Water
(Water treatment refers to the physical and chemical measures taken to ensure that water quality meets certain usage standards. The minimum standards for drinking water are formulated by the environmental protection department. However, industrial water has different requirements in different industries. The physical characteristics of water, such as temperature, color, transparency, odor, and taste, are the basic criteria for judging the quality of water. The chemical properties of water, such as acidity and alkalinity, concentration of dissolved solids, and oxygen content, are also important criteria for judging water quality.)
Drinking water
Urban drinking water, also known as drinking water, is water that has undergone multiple processes in a water treatment plant and meets the requirements of human consumption re gulations. Clean drinking water can be delivered to consumers from many sources, including public or private water supply systems or bottled water. Raw water can be collected from various sources, including but not limited to lakes, rivers, and underground aquifers. Before entering the water treatment plant, these water sources may have already been contaminated, so it is necessary to properly treat the water before drinking to remove potential harmful factors. Most drinking water processes include coagulation and flocculation, sedimentation, filtration, and disinfection steps. The regulatory standards and supervision for treatment vary around the world. Many countries follow the guidelines established by the World Health Organization. The European Union, the United States of America, and other developed countries have adopted stricter standards.
Seawater Dealination
Although water covers 70% of our planet, the scarcity of freshwater has affected over 40% of the world's population. Desalination of seawater is one of the solutions to address this issue. It includes the removal of minerals (mainly salts) from seawater through physical and chemical processes. Saudi Arabia is the leading desalination country by volume, followed by the United Arab Emirates, both of which are desert countries and highly dependent on this process. Other countries in the Middle East, such as Kuwait and Qatar, have also opted for this technique. In the United States, third in this particular ranking, there are desalination micro-plants close to almost all the natural gas facilities to exploit the residual heat. Reverse osmosis is the most used process and consumes less energy than the rest, as it is based on the use of semipermeable membranes that allow the water to pass, but not the salt. These membranes are made of ultra-thin polyamide, which can become contaminated with bacteria so the water must be treated. But after a long period of filtration, the membrane elements will attach a large amount of salt and heavy metal ions. If not cleaned, it will block the membrane pores, greatly reduce the filtration efficiency, and shorten the service life of the membrane elements. Sinoblue provides various chemical solutions for solving and cleaning membrane components to ensure efficient and continuous process of seawater desalination.
Wastewater treatment
Wastewater(Common wastewater consists of domestic wastewater and industrial wastewater. The pollution caused by industrial wastewater, mainly including organic aerobic substance pollution, chemical toxin pollution, inorganic solid suspension pollution, heavy metal pollution, acid pollution, alkali pollution, plant nutrient pollution, heat pollution, pathogen pollution, etc. Many pollutants have color, odor or easy to generate foam, so industrial wastewater often presents an offensive appearance, causing large-scale water pollution, directly threatening the lives and health of the people. Therefore, it is particularly important to control industrial wastewater. Domestic sewage refers to the wastewater discharged by people in
their daily activities, which is mainly polluted by domestic waste and human excrement. The quantity, composition, and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for microbial reproduction and contains a large number of bacteria and pathogens. From a hygiene perspective, it has a certain degree of harm.
