Sand Filter, Carbon Filter, Fully Automatic Reverse Osmosis Precision Water Filtration Mechanical Equipment

Product description

Sand Filter
Structure and filter material: It is usually a cylindrical container filled with filter materials such as quartz sand. Quartz sand particles vary in size, with the upper layer being a finer sand layer and the lower layer being a coarser sand layer.
Working principle: When water flows in from the top of the sand filter and passes through the filter material layer, suspended solids, colloids, and other impurities in the water are trapped on the surface and pores of the filter material, thereby achieving preliminary purification of the water. As filtration progresses, the filter material will gradually be blocked by impurities, and when it reaches a certain level, backwashing is required. During backwashing, the water flow direction is opposite to the normal filtering direction. Through the impact and friction of the water flow, impurities trapped on the filter material are washed away, restoring the filtering performance of the filter material.
Function: It mainly removes impurities such as sediment and rust from larger particles in water, reduces water turbidity, provides a relatively clean water source for subsequent water treatment steps, and protects subsequent equipment from damage caused by large particle impurities.
Carbon Filter
Structure and filter material: The interior is filled with activated carbon, which has a rich microporous structure and a huge specific surface area.
Working principle: By utilizing the adsorption effect of activated carbon, when water passes through the activated carbon layer, residual chlorine, organic matter, pigments, odors and other substances in the water are adsorbed on the surface of the activated carbon. The adsorption of activated carbon includes physical adsorption and chemical adsorption. Physical adsorption is based on intermolecular attraction, while chemical adsorption is the chemical reaction between the active groups on the surface of activated carbon and the adsorbed substance.
Function: Effectively remove residual chlorine from water and prevent oxidative damage to the reverse osmosis membrane caused by residual chlorine; Remove organic pollutants and odors from water, improve water taste and odor, and enhance water quality.
Maintenance: After a period of use, the adsorption capacity of activated carbon will gradually decrease, and it is necessary to regularly replace the activated carbon to ensure its adsorption effect.
Fully Automatic Reverse Osmosis Precision Water Filtration Mechanical Equipment
Working principle: By utilizing the characteristics of a semi permeable membrane, water passes through it under pressure, and impurities such as salt, bacteria, viruses, and organic matter in the water are intercepted, thereby achieving deep purification of the water. The fully automatic reverse osmosis equipment is equipped with an advanced control system, which can automatically complete operations such as water production, flushing, and protection. When the water quality, pressure and other parameters of the raw water change, the system can automatically adjust them to ensure the stable operation of the equipment and the compliance of the effluent water quality.
System composition:
High pressure pump: provides sufficient pressure for the reverse osmosis membrane to allow water to pass through the semi permeable membrane.
Reverse osmosis membrane element: It is the core component of equipment, commonly available in roll and hollow fiber structures, and has the characteristics of high desalination rate and high water flux.
Control system: Using PLC programmable controller and human-machine interface, real-time monitoring of system parameters such as pressure, flow rate, water quality, etc., and automatic control of equipment operation according to the set program, such as automatic flushing of reverse osmosis membrane, automatic dosing, etc.

Pre treatment system: including sand filters, carbon filters, precision filters, etc., to remove suspended solids, colloids, organic matter, residual chlorine and other impurities in raw water, and protect reverse osmosis membrane components from pollution and damage.

characteristic:
High desalination rate: It can effectively remove various impurities and harmful substances from water, and the quality of the produced water is high. The desalination rate can usually reach over 98%.
High degree of automation: No need for frequent manual operations, reducing labor intensity and operating costs.
Stable water quality: It can continuously and stably produce water quality that meets the requirements and meets the strict water quality requirements of different industries.
This combination of water treatment equipment is widely used in industrial production, drinking water treatment, laboratory water and other fields, which can effectively remove impurities and harmful substances from water and provide high-quality purified water.
