Sand Filter Carbon Filter Belt Softening Fully Automatic Reverse Osmosis Water Filtration System

Product description

Sand Filter

Function: Mainly used to remove various suspended solids, microorganisms, and other fine particles in water, reduce water turbidity, and achieve preliminary purification of water quality. For example, it can filter out impurities such as sediment and rust in water.
Working principle: During normal operation, the water that needs to be filtered reaches the medium layer through the inlet, and most of the pollutants are trapped on the surface of the medium. Small pollutants and other floating organic matter are trapped inside the medium layer. When the amount of impurities and suspended solids in the water reaches a certain level, the pressure difference control device will detect the inlet and outlet pressure difference in real time. When it reaches the set value, the electric control PLC will control the three-way hydraulic control valve, close the inlet channel, open the sewage channel, and use water from other filtration units to flush and clean the medium layer of the unit.
Structure composition: usually composed of a filtering system and a control system. The filtration system includes high-efficiency filtration units, three-way automatic valves, inlet and outlet pipelines, sewage pipelines, etc; The control system consists of PLC timing controller, differential pressure controller, electromagnetic three-way valve, etc.

Carbon Filter

Function: Mainly used to adsorb residual chlorine, organic matter, odors, and pigments in water, improving the taste and odor of water. For example, it can effectively remove the chlorine odor generated by disinfection in water, as well as some organic pollutants in water.
Working principle: Utilizing the adsorption effect of activated carbon, which has a huge specific surface area and rich microporous structure, these micropores can adsorb various molecules and ions in water, thereby achieving the goal of purifying water quality.
Common types include granular activated carbon (GAC) filters and carbon block filters. The granular activated carbon filter has a large adsorption area and can effectively remove organic matter and residual chlorine from water; Activated carbon rod filters have higher filtration accuracy and can remove smaller particles and organic matter.

Belt Softening Device

Function: Mainly to reduce the content of calcium and magnesium ions in water, prevent the formation of scale, and protect subsequent reverse osmosis membranes and other equipment. For example, in household water, softened water can reduce the accumulation of scale on devices such as water heaters and faucets.
Working principle: Generally, ion exchange resin technology is used, in which sodium ions on the resin exchange with calcium and magnesium ions in water, adsorbing calcium and magnesium ions on the resin and releasing sodium ions into the water, thereby reducing the hardness of the water. When the calcium and magnesium ions adsorbed by the resin reach saturation, it is necessary to regenerate the resin with salt water to restore its exchange capacity.

Fully Automatic Reverse Osmosis System

Function: It is the core part of the entire water filtration system, capable of removing various pollutants such as bacteria, viruses, salts, organic matter, etc. from water, and producing high-quality purified water. It can be widely applied in fields such as drinking water treatment, industrial production, pharmaceuticals, laboratories, etc.
Working principle: Under pressure, water passes through a semi permeable membrane, while impurities, salts, and other substances in the water are trapped on the other side of the membrane, thereby achieving water purification and separation. Specifically, a high-pressure pump pressurizes water to overcome osmotic pressure and pass through a reverse osmosis membrane. Pure water passes through the membrane to become produced water, while concentrated pollutants are discharged as concentrated water.
System composition: usually includes pre-treatment system, high-pressure pump, reverse osmosis membrane components, and post-treatment system. The pretreatment system is used to remove suspended solids, sediment, chlorine, and color from water, protecting the reverse osmosis membrane; The high-pressure pump provides power to push water through the reverse osmosis membrane; Reverse osmosis membrane components are key components for achieving water purification; The post-processing system can include steps such as activated carbon filtration and ultraviolet disinfection to further improve the purity of water quality.
This comprehensive water filtration system can provide high-quality purified water, meet the strict requirements of different fields for water quality, and the fully automatic operation mode reduces the workload of manual operation and maintenance, improving the stability and reliability of the system.
