Integrated water purification device

I. Overview
The FA type fully automatic water purification device is a series of new products developed by our company. The water purification capacity is divided into five different models: 10, 30, 50, 100, and 200 tons/hour (special specifications and requirements can be designed and manufactured separately).
This series of water purification devices integrates the essence of flocculation, sedimentation, sewage discharge, backwashing, water collection filtration and other processes, and can achieve the full automatic operation of single water purification devices without personnel operation. It is an important unit to realize the automatic management of the water plant. With the ZJ automatic dosing device and disinfection equipment produced by the plant, it can become a water purification station (plant) with a full set of functions.
This series of water purification devices not only has a wide range of applications, good treatment effects, and excellent effluent quality, but also consumes less water, consumes less power, occupies a small area, saves water, electricity, and labor, and can be a new energy-saving product that eliminates the need for auxiliary pumps and facilities.

2、 Scope of application
1. Suitable for water plants in rural, urban, industrial and mining enterprises with various rivers, lakes, reservoirs and other water sources with turbidity less than 3000mg/L, as the main water purification treatment device.
2. For lake water sources with low temperature, low turbidity, and seasonal algae, they have special adaptability.
3. Pre treatment equipment for high-purity water, beverage industry water, boiler water, etc.
4. Used in various industrial circulating water systems, it can effectively and significantly improve the quality of circulating water.
5. Used in the middle water channel system, the treatment equipment uses the effluent from the sewage treatment plant as the water source for purified water reuse.

3、 Main features
1. In addition to managing the pump room and dosing system, the water purification device itself meets the requirements of automatic operation through a series of operating procedures such as reaction, flocculation, sedimentation, sludge collection, sludge discharge, water collection, water distribution, filtration, backwashing, and sewage discharge. The on duty personnel only need to perform regular water quality monitoring and measurement work, and do not need to manage the operation of the water purification device.
2. A high concentration flocculation layer can provide sufficient collision contact and adsorption probability for impurity particles in raw water, thus adapting to various water temperatures and turbidity of raw water, and achieving high removal rate of impurity particles. Under certain usage conditions, it also has the function of removing algae.
3. The rapid sludge concentration chamber and adjustable automatic sludge discharge system can ensure timely removal of excess sludge impurities, thereby ensuring a stable removal rate of impurity particles.
4. The coagulation and sedimentation effects ensure that the effluent quality remains in good condition.
5. The innovative water collection system and water collection head make the water collection more uniform and effective, not only improving the volume utilization coefficient, but also accumulating considerable energy-saving effects due to its extremely small water collection head.
6. The automation of the water purification system not only ensures the filtration of the water purification system (when the turbidity of the raw water is less than 3000mg, the turbidity of the filtered water can be maintained below 3mg), but also can automatically backwash without the need for additional electrical equipment such as backwash water pumps or air compressors, which can save a lot of infrastructure investment and daily operation, maintenance, and upkeep costs.
7. The low self consumption rate of water is about<5%, which plays a positive role in saving limited water resources.
8. Small footprint, compared to general water purification structures, it can save less than 50% of land, with a height of about 4.10 meters, and can be installed indoors and outdoors.
9. Easy to expand, renovate, reuse, relocate or relocate.

4、 Process flowchart

The above structures can be combined and constructed according to specific circumstances. In the absence of a water tower, the fully automatic pneumatic water supply produced by our company can be used, and auxiliary equipment such as JY type dosing device and disinfection equipment are provided by our company.

5、 Design parameters
1. Applicable raw water turbidity: ≤ 3000mg/L
2. Applicable raw water temperature: room temperature
3. Turbidity of purified water outlet: ≤ 3mg/L
4. Surface load design for sedimentation zone: 7-8M3/H · M2
5. Filter zone design filtration rate: 8-10M/H
6. Filter flushing intensity: 14-16L/S · M2
7. Rinse duration: t=4-6min (adjustable)
8. Total dwell time: Total T=40-45 minutes
9. Inlet pressure: ≈ 0.06MPa

6、 List of selected parameters such as pipeline, power supply, pump type, etc. (click to view detailed information)
Note:
1. The direction of the inlet connections for the various pipelines mentioned above can be changed by 180 degrees to meet the overall layout requirements.
2. The applicable conditions for the selection of reference pump types and motor power are: the difference between the dry water level of the water pump and the operating water level of the water purification device is not more than 8 meters, and the sum of losses along the way and locally from the water source to the water purification device is not more than 4 meters. If the hydraulic conditions at the application site do not match the above situation, a different pump should be selected according to the actual situation.

7、 List of Dimensions for Each Part

Note: The outlet elevation of the water purification device is 2.5 meters (relative elevation). Based on the pipeline layout and distance of the water purification device and the clean water tank, calculate the sum of losses along the way and locally. Subtracting the sum of hydraulic losses from 2.5 meters can determine the relative elevation value of the high water level in the clear water tank.

8、 Installation and maintenance
1. This water purification device is an integrated water purification unit, which is placed on a foundation poured and compacted according to design requirements. It can be put into operation by connecting the inlet and outlet pipes.
2. The inlet pipe must be equipped with a flow meter.
3. This device requires the introduction of a 380V three-phase power supply for fully automatic control.
4. This device generally does not require maintenance or upkeep, but the filter material can be inspected once a year. If the thickness of the filter material is insufficient, quartz sand with a particle size of 0.50-1.2 millimeters can be used to supplement it to the required height.

9、 Scope of complete supply
1. The inlet pipes, inlet valves, outlet pipes, drainage pipes, and sludge discharge pipes outside the water purification device are not included in the scope of supply.
2. Inspection of walkways, platforms, and escalators is not included in the scope of supply.
3. Install and debug on behalf of the user, with additional charges.
4. Excluding the filter material required for the device, the quantity should be purchased by the supplier according to their requirements.
