The integrated automatic backflush water purifier is a new generation water purification equipment independently developed by our company, absorbing and integrating domestic and international technologies. It boasts fast construction cycles, cost-effective comprehensive investment, compact and flexible layout, minimal land occupation, excellent output water quality, 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 the treatment of small and medium-sized water purification stations in urban water supply and industrial and mining enterprises. Since its launch, it has provided this convenient device to numerous users, earning a good reputation.
Performance Features
The integrated automatic backflush water purifier main unit is made of steel structure, manufactured into finished products at our factory. Upon arrival at the site, it can be installed and debugged for immediate use, with a fast construction cycle. Unconvenient for transportation can be manufactured and installed on-site.
The integrated automatic backflush water purifier has been designed with full consideration of regional differences in water quality. It not only rationally selects dosing points but also adds coagulation reaction functionality, ensuring sufficient coagulation reaction time. The design is conservative in surface loading, enhancing the equipment's ability to withstand shock loads, making it more suitable for varying water quality conditions in different regions. The filtration system employs low-resistance water distribution for deep slow filtration, ensuring the turbidity of the treated water after filtration.≤3Degrees.
The integrated automatic backflush water purifier is designed with a focus on convenience and practicality, featuring simple operation. The entire system cleverly utilizes hydraulic characteristics for automatic operation, with minimal requirements for operator qualifications, making it easily manageable by most individuals. It can automatically control the equipment's operational features. When the filter layer becomes sufficiently clogged, it automatically backflushes. The entire unit has no moving parts, resulting in virtually zero equipment failures, ensuring reliable operation and ease of maintenance.
Operating Principle
The integrated automatic backflush water purifier consists of two main parts: a rapid inclined tube sedimentation tank and a gravity filter. Its working principle and technical features are as follows:
1Quick Inclined Tube Sedimentation Tank
The Rapid Inclined Plate Sedimentator is an improved version of the traditional horizontal flow sedimentator, featuring inclined plates inside the sedimentator to increase the sedimentation area, thereby significantly enhancing the efficiency of the sedimentator. This results in an increased water output for sedimentators of the same area. In other words, under the premise of treating the same volume of water, the volume of the equipment (or unit) can be reduced, thereby reducing equipment investment. In addition to reducing the equipment volume with the inclined plates, the hydraulic conditions are also technically improved: when the diameter and spacing of the inclined plates are sufficiently small (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, enhancing a coagulation reaction zone. After raw water enters, it first undergoes coagulation and reaction where suspended impurities絮凝 into larger particles, and then proceeds to the sedimentation zone to ensure effective sedimentation. Due to the presence of a reaction zone, the sedimentation tank of this equipment has a longer coagulation time and better sedimentation effect compared to traditional integrated water purifiers. Generally, the incoming water turbidity is1000ppmAt the domestic level, the turbidity of the settler outlet water has already ≤15ppm。
2Gravity-assisted automatic backwashing filter
This device is designed with an automatic hydraulic backflush, its working principle is as follows:
The filtration process is as follows: After sedimentation or clarification, the clear water is then passed through the water distribution trough.UTubular elements enter the siphon riser, where water is evenly distributed over the filter medium by baffles inside the top cover. Water then filters downwards through the medium. Filtered water is channeled into the collection area, the water outlet tank, via a low-pressure distribution system. As the water level rises to the outlet pipe, the filtered water flows into the clear water reservoir.
The filter bed is relatively clean when it is newly put into operation. However, as the filter bed runs for a certain period of time, the gradual increase of solid particle impurities in the bed causes the head loss to rise accordingly. The water level along the siphon rise pipe slowly ascends. Once the head loss reaches a certain level, the water in the siphon rise pipe rises to the siphon auxiliary pipe opening and rapidly flows down. 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 amount of water in the siphon rise pipe overflows the top and falls along the siphon drop pipe, marking the beginning of the backwash process. The water from the rinse tank is flushed upward through the pipeline, collection area, and distribution system to rinse the filter bed. The rinse wastewater is then drained into the drain well through the siphon pipe. During the rinse process, the water level in the tank gradually decreases, approximately...5minLeft or right, when the water level in the tank drops to the siphon breaker, the siphon is destroyed, and the flushing process ends, filtering restarts.
Setting up this device eliminates the need for traditional mechanical backwash pumps and the use of clean water from the reservoir for backwashing. This simplifies the entire system by reducing the need for backwash pumps, related piping, valves, and fittings, significantly easing the operational and management workload as well as equipment investment. Since backwashing is automatic based on the degree of filter layer clogging, it minimizes human operation errors, allowing the entire unit to function even without human intervention.
This demonstrates that the adoption of a modularized, integrated water purification system for medium and small-scale water plants offers numerous advantages unmatched by other equipment. Its use simplifies, facilitates, and enhances the reliability of the entire treatment system. Technically and economically, it outperforms traditional water purification systems. Currently, this product is increasingly being applied in small water plants, having become the replacement for conventional purification systems.
