Integrated Water Purification System

Integrated automatic backflush water purifier

SummaryDescribed

The integrated automatic backflush water purifier is a new generation of water purification equipment independently developed by our company by absorbing 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, the product has provided this convenience to numerous users and has earned a good reputation.

Performance Features

The main unit of the integrated automatic backflush water purifier is made of steel structure, manufactured as finished products in our factory. Upon arrival at the site, it can be installed and debugged for immediate use, with a fast construction cycle. For items that are not convenient for transportation, on-site manufacturing and installation can be arranged.

The integrated automatic backflush water purifier has been designed with full consideration of regional water quality differences. It not only selects the dosing points reasonably but also adds coagulation reaction functionality, ensuring sufficient coagulation reaction time. The surface load is designed conservatively to enhance the equipment's ability to withstand shock loads, making it more suitable for varying regional water quality conditions. The filtration system employs low-resistance water distribution for deep slow filtration, ensuring the turbidity of the treated water after filtration.≤3Degree.

The integrated automatic backflush water purifier is designed with a focus on convenience and practicality, featuring simple operation. The entire system ingeniously utilizes hydraulic properties for automatic operation, with minimal requirements for operator proficiency, allowing most individuals to operate it effortlessly. It also automatically controls the equipment's operational characteristics. When the filter layer becomes sufficiently blocked, 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 components: a rapid inclined tube sedimentation unit and a gravity filter. Its working principle and technical features are as follows:

     1Quick Inclined Tube Sedimentation Tank

      The Rapid Inclined Plate Settler is an improved version of the traditional horizontal flow settler, featuring inclined plates within the settler to increase the settling area, thereby significantly enhancing the efficiency of the inclined plate settler. This increase in settling area allows for an equivalent area settler to produce more water output, in other words, under the same water treatment volume, the volume of the equipment (or device) can be reduced, thereby decreasing equipment investment. Along with the reduction in equipment volume due to the inclined plates, the hydraulic conditions are also technically greatly improved: when the diameter and spacing of the inclined plates are sufficiently small (usually),30mm(Left and right), the water flow is in a laminar state, at this point, the sedimentation of particles is not disturbed by the water flow, improving a coagulation reaction zone. After raw water enters, it first goes through a coagulation reaction where suspended impurities絮凝 into larger particles, then it enters the sedimentation zone, ensuring the sedimentation effect. Due to the presence of a reaction zone, the sedimentation tank of this equipment has a longer coagulation time and better sedimentation effect than traditional integrated water purifiers. Generally, the incoming water turbidity is1000ppmDuring in-process, the turbidity of the sedimentation tank effluent has already ≤15ppm。

   2Gravity Feed Automatic Backwash Filter

      This device is designed for hydraulic automatic backflushing, and its working principle is as follows:

      The filtration process is: 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 put into operation. However, as it runs for a certain period, the water head loss increases gradually due to the gradual accumulation of solid particle impurities in the filter bed. Consequently, the water level rises slowly along the siphon rising pipe. Once the water head loss reaches a certain point, it causes the water level in the siphon rising pipe to rise to the siphon auxiliary pipe, flowing down rapidly. Relying on the entrainment and jetting effects of the water flow and the continuous removal of air from the siphon pipe by the suction pipe, a vacuum is formed in the siphon pipe. The water in the siphon rising pipe then surges over the top and falls along the siphon descending pipe, marking the beginning of the backflushing process. The backflushing water from the storage tank flows upwards through the connecting pipes, the collection area, and the distribution system to rinse the filter bed. The rinsing wastewater enters the drain well through the siphon pipe. During the rinsing process, the water level in the tank gradually decreases, approximately...5minAlright, when the water level in the tank drops to the siphon breaker, the siphon is disrupted, and the flushing process ends, with filtration restarting.

Setting up this device eliminates the need for traditional mechanical backflush pumps and avoids using clean water from the reservoir for backflushing. This simplifies the entire system by reducing the need for backflush pumps, related piping, valves, and fittings, significantly easing operation and management intensity as well as equipment investment. Since backflushing is automatic based on the degree of filter clogging, it minimizes human operation errors, allowing the entire unit to operate even without human intervention.

It is evident that the adoption of a modular integrated water purification system as the purification facility for small to medium-sized water plants offers numerous advantages unmatched by other equipment. Its implementation simplifies, facilitates, and enhances the reliability of the entire treatment system. Technically and economically, it outperforms traditional water purifiers. Currently, this product is increasingly being used by a growing number of users in small-scale water plants, having become the replacement for conventional water purification systems.
