The reverse osmosis water purification system uses membrane separation technology to remove charged ions, inorganic substances, colloidal particles, bacteria and organic substances in water. One-time removal of more than 98% of ions, organic matter and 100% of microorganisms in raw water, as well as a variety of dissolved and suspended chemical substances and biological substances (mainly bacteria) in water, and to asbestos, a variety of chemical substances that produce taste, color and odor, Particulate, total dissolved solids, turbidity and radium are also effective for industrial processes and drinking water production.

The working principle of the stacked screw sludge dewatering machine is based on the screw extrusion principle, which achieves solid-liquid separation and dewatering concentration of sludge through the rotation of the screw shaft. It can be divided into three stages: concentration, dewatering, and sludge unloading, and has self-cleaning function

Mechanical grates are a type of equipment specifically designed for water treatment, capable of continuously and automatically intercepting and removing various shapes of impurities from the flowing fluid. They are widely used in urban sewage treatment. It is one of the most advanced solid-liquid separation devices in China, applied in the water supply industry, power plant entrances, and also serves as the front-end screening equipment in wastewater treatment processes of industries such as textiles, food processing, papermaking, and leather.

Automatic dosing device is used for the treatment of water supply, boiler water, circulating water, wastewater, etc. in power plants, and can also be used in industries such as petroleum, chemical, environmental protection, and water supply systems. The application of automatic dosing devices in ventilation engineering: High concentrations of chemical scales such as calcium carbonate and magnesium carbonate, as well as household sludge, can deposit in high-temperature condenser areas, resulting in a serious decrease in the cooling capacity of the main unit. This requires an automatic dosing device to treat the water quality.

The electrical control cabinet is a device that integrates switchgear, measuring instruments, protective devices and auxiliary equipment according to electrical wiring requirements, and is assembled in a closed or semi-closed metal cabinet or screen panel. Its layout should meet the requirements for normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment.

Aerator ‌ is essential equipment for aeration and oxygenation in water supply and drainage. It is mainly used in water treatment processes, especially playing a key role in sewage treatment and water supply treatment. Aerators increase the dissolved oxygen content in water by injecting air into it to meet the metabolic requirements of microorganisms, thereby promoting the biological treatment of wastewater

Activated carbon, also known as activated carbon black, is an amorphous carbon and a functional material. Its main component is carbon, with a carbon framework structure. It also contains trace amounts of oxygen, hydrogen, nitrogen, sulfur, etc., thereby forming various functional groups and rich pore structures. It is in the form of black powder or particles, with a unique microcrystalline structure, well-developed pores, a high specific surface area, and a lower density than water. It has excellent adsorption properties, is hydrophobic, can accept water molecules; it can withstand strong acids and strong bases, can be heated at high temperatures, has high mechanical strength, is conductive, and has stable chemical properties. The edges, misalignments, discontinuities, unpaired electrons, and residual valence states in the aromatic sheets of activated carbon are highly reactive areas, which can interact with substances containing oxygen, hydrogen, nitrogen, or sulfur, participating in different surface reactions and catalytic reactions.

Environmental-friendly fillers are important functional materials in fields such as wastewater treatment and gas purification. Common environmental-friendly fillers include biodegradable fillers and adsorption fillers, etc. They possess high biodeposition ability and large physical surface area, which can enhance the biodegradation and filtration functions of the treatment system, achieving the effect of purifying water quality or air. Moreover, environmental-friendly fillers are environmentally friendly and pollution-free, have a long lifespan, are suitable for long-term use, and can effectively reduce maintenance costs and economic investment costs.
