Reverse Osmosis Belt Softened Sand Filter Carbon Filter Impurity Water Treatment System

Product description

Components and Their Functions

1. Sand Filter
   • The sand filter is the first stage of pre-treatment in this system. It consists of a container filled with graded sand media. As water passes through the sand bed, suspended solids, sediment, and larger particles are trapped. The sand acts as a physical barrier, removing impurities based on their size. This helps to protect the subsequent treatment components from clogging and reduces the load on the other filters.
2. Softening Unit
   • In the softening stage, the water treatment system aims to remove hardness ions such as calcium and magnesium. This is usually achieved through ion exchange resins. The resin beads have a high affinity for calcium and magnesium ions and exchange them with sodium ions. As a result, the water leaving the softening unit has a reduced hardness level, which is important for preventing scale formation in the reverse osmosis membrane and downstream equipment.
3. Carbon Filter
   • The carbon filter uses activated carbon to remove organic compounds, chlorine, and odors from the water. Activated carbon has a large surface area and porous structure, which allows it to adsorb a wide range of contaminants. Chlorine, in particular, can damage the reverse osmosis membrane, so its removal by the carbon filter is crucial for the long-term performance of the system.
4. Reverse Osmosis (RO) Unit
   • The reverse osmosis unit is the core of the water treatment system. It uses a semi-permeable membrane that allows water molecules to pass through while blocking dissolved salts, heavy metals, bacteria, and other contaminants. Under pressure, water is forced through the RO membrane, resulting in highly purified water on one side and a concentrated brine solution on the other side. The RO process can remove up to 99% of many dissolved substances, making it highly effective in producing high-quality purified water.

Advantages of the System

1. Comprehensive Impurity Removal
   • By combining multiple filtration and treatment stages, this system can effectively remove a wide variety of impurities from water, including suspended solids, hardness ions, organic compounds, and dissolved salts.
2. Protection of RO Membrane
   • The pre-treatment steps (sand filter, softening, and carbon filter) help to protect the reverse osmosis membrane from damage and fouling. This extends the lifespan of the RO membrane and reduces the need for frequent membrane replacement, which can be costly.
3. Improved Water Quality
   • The treated water has a significantly improved quality, with reduced levels of contaminants. This makes it suitable for a wide range of applications, such as drinking water, industrial processes, and laboratory use.

Applications

1. Domestic Water Treatment
   • It can be used in households to provide high-quality drinking water and to protect household appliances (such as water heaters and washing machines) from scale and other contaminants.
2. Industrial Water Treatment
   • In industries like electronics, pharmaceuticals, and food and beverage, where high-purity water is required, this system can meet the strict water quality standards. For example, in the electronics industry, it is used for cleaning and rinsing components, and in the pharmaceutical industry, it is used for the production of drugs and medical devices.
3. Commercial Applications
   • In commercial buildings such as hotels, restaurants, and offices, this system can provide clean and safe water for various purposes, including drinking, cooking, and cleaning.
