The main task of a water treatment plant is to purify raw water so that it reaches safe drinking standards. Specifically, they purify water from rivers, lakes or groundwater through a series of physical, chemical and biological treatment processes.

The service life of a reverse osmosis water purification system is typically between 10 and 15 years. The life of the system depends on a variety of factors, including water quality, maintenance, and the quality of the system components. Frequent cleaning and replacement of filters and reverse osmosis membranes can help extend the life of your system.

Reverse osmosis technology is not only suitable for seawater desalination, but is one of the most advanced, effective and environmentally friendly seawater desalination technologies currently available. This method shows extremely high efficiency in the seawater desalination process and can quickly convert seawater into clean fresh water. Reverse osmosis technology uses less energy and produces significantly fewer greenhouse gas emissions than other desalination methods.

The invention of desalination technology originated in the mid-20th century and was first patented by Alexander Zarchin. His desalination method is based on freezing seawater to form pure water crystals in a vacuum environment, which are then melted to create salt-free water. Chachin's invention laid the foundation for the early stages of desalination technology, but scientists and engineers produced many innovations in the field in the decades that followed.

1. Cost range: According to the World Bank, the cost of solar desalination typically fluctuates within a range per cubic meter of water produced. The average cost is approximately US$0.72-1.50, depending on a variety of factors, including technology selection, energy costs, equipment and material costs, and the geographical and climatic conditions of the project location.

A seawater treatment plant, also known as a desalination plant, is a facility that converts seawater into fresh water through desalination technology. Its main technologies include reverse osmosis (RO), multi-stage flash evaporation (MSF) and multi-effect distillation (MED). Reverse osmosis is currently the most common desalination technology. It uses high pressure to force seawater through a semi-permeable membrane, removing salt and other impurities, and ultimately obtaining pure fresh water.

The operation of industrial water treatment plants is mainly divided into two basic stages: primary stage and secondary stage. First, in the primary stage, water treatment plants focus on removing solid particles and suspended solids from the water. Next is the secondary stage, which mainly uses biological treatment technology and uses microorganisms to decompose organic matter in the wastewater.

The most common water treatment methods include boiling, filtering, and using water treatment equipment. These methods are widely used worldwide to ensure the quality and safety of drinking water.

Saltwater water purifiers do exist, and a saltwater water purifier is a water filtration system specifically designed to filter and desalinate saltwater. This system utilizes unique technology to remove dissolved salts from brine, thereby converting it into fresh water. This technology plays an important role in the field of water purification, providing new solutions for areas lacking fresh water resources.
