Please provide the Chinese content to be translated.Described

The integrated automatic backflush water purifier is a new generation of water purification equipment independently developed by our company, integrating domestic and international technologies. It boasts quick construction cycles, cost-effective comprehensive investment, compact and flexible design, minimal land occupation, excellent water quality output, and simple operation and maintenance. It is an ideal equipment for urban water supply and industrial and mining enterprise water purification. The treated water quality meets the national "Sanitary Standard for Drinking Water." The introduction of this equipment provides a more convenient approach for water purification stations in urban water supply and industrial and mining enterprises, especially for small and medium-sized water supply stations. Since its launch, the product has provided this convenience to numerous users and has earned a good reputation.

Performance Features

The integrated automatic backflush water purifier main unit is made of steel structure and is manufactured into finished products at our factory. It can be delivered to the site, installed, and ready for use with minimal construction time. For items that are not convenient to transport, on-site manufacturing is available.

The integrated automatic backflush water purifier has also taken into account the regional differences in water quality in its design. While selecting rational dosing points, it has added coagulation reaction functions, ensuring sufficient coagulation reaction time for the device. It has also conservatively designed the surface load, making the equipment more capable of withstanding shock loads, and more suitable for varying water quality conditions in different regions. The filtration system uses low-resistance water distribution for deep slow filtration, ensuring the turbidity of the treated water after filtration.≤3Degree.

Integrated automatic backflush water purifier, designed with a focus on convenience, practicality, and ease of operation, cleverly utilizes hydraulic characteristics for automatic operation. It requires minimal operator skill, allowing most individuals to operate it effortlessly and control the equipment's operational features automatically. When the filter surface becomes sufficiently clogged, it automatically backflushes. The entire unit has no moving parts, resulting in almost zero equipment failures, reliable operation, and ease of maintenance.

Principle of Operation

The integrated automatic backflush water purifier consists of two main parts: the rapid inclined tube sedimentation tank and the gravity filter. Its working principle and technical characteristics are as follows:

     1Quick Slope Tube Settler

      The Rapid Inclined Plate Settler is an improved version of the traditional horizontal flow settler. By incorporating inclined plates within the settler, the settling area is increased, significantly enhancing the efficiency of the inclined plate settler. This results in a higher water output for the same settling area. In other words, under the same water treatment volume, the volume of the equipment (or unit) can be reduced, thereby reducing equipment investment. Along with reducing the equipment volume through the inclined plates, the hydraulic conditions are also greatly improved technically: with small pipe diameters and spacing of the inclined plates (usually...30mm(Left to right), the water flow is in a laminar state, at which point the settling of particles is not disturbed by the water flow, increasing the efficiency of a coagulation reaction zone. After raw water enters, it first goes through the coagulation reaction where suspended impurities絮凝 into larger particles, and then into the sedimentation zone to ensure effective sedimentation. Due to the presence of the reaction zone, the sedimentation tank of this equipment has a longer coagulation time than traditional integrated water purifiers and better sedimentation performance. Generally, the incoming water turbidity is1000ppmAt the domestic level, the turbidity of the sedimentation tank's outlet water has already ≤15ppm。

   2Gravity-assisted automatic backwash filter

      The device is designed for hydraulic automatic backflush, with its operational principle as follows:

      The filtration process involves: Clear water after sedimentation or clarification, followed by the water distribution trough,UThe tube enters the siphon riser, where water is evenly distributed over the filter medium by the water distribution baffles inside the top cover. Water then filters through the medium from top to bottom. The filtered water flows into the collection area through a low-resistance water distribution system, which is the storage tank. When the water level rises to the outlet pipe, the filtered water is transferred to the clear water tank.

      The filter bed is relatively clean when it is newly operational. However, as the operation continues and solid particles and impurities gradually accumulate in the filter bed, the water head loss increases accordingly. The water level then slowly rises along the siphon riser pipe. Once the water head loss reaches a certain point, it causes the water level in the siphon riser pipe to rise rapidly to the siphon auxiliary pipe, where it flows down swiftly. Relying on the entrainment of air and the jet action of the water flow, as well as the continuous removal of air from the siphon pipe by the suction pipe, a vacuum is formed in the siphon pipe. Consequently, a large volume of water in the siphon riser pipe overflows the top and falls down the siphon drop pipe. This marks the beginning of the backwashing process. The water from the rinse tank is flushed upwards through the connecting pipes, the collection area, and the distribution system to rinse the filter bed. The rinse wastewater then flows into the drainage well through the siphon pipe. During the rinse process, the water level in the tank gradually decreases, approximately...5minAlright, as the water level in the tank drops to the siphon buster, the siphon is disrupted, ending the flushing process, and the filtration restarts.

Setting up this device eliminates the need for traditional mechanical recirculation pumps and the requirement to draw clean water from the reservoir for backwashing. This simplifies the entire system, reducing the need for backwashing pumps and associated pipes, valves, and fittings, significantly easing operational and management intensity as well as equipment investment. As backwashing is automated based on the degree of filter media clogging, it minimizes human operational errors, allowing the entire unit to function even without human operation.

It is evident that the use of a modular automatic integrated water purification system as the purification facility for small and medium-sized water plants offers numerous advantages unmatched by other equipment. Its adoption will simplify, facilitate, and enhance the reliability of the entire treatment system. It outperforms traditional water purifiers in both technology and economics. Currently, this product is increasingly being applied in small water plants and has become the replacement for traditional water purifiers.
