1、 Overview
The JDHF-A high-efficiency fully automatic water purification device is a series of new products developed by Wuxi Jiangdaliansheng Water Treatment Technology Co., Ltd. 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 have a wide range of applications, good treatment effects, and excellent effluent quality, but also consume less water and save power consumption
A new energy-saving product with a small land area, which saves water, electricity, and labor, and can eliminate the need for auxiliary machines, pumps, and facilities.
Scope of Application
1. Suitable for water plants in rural, urban, industrial and mining enterprises with various rivers, lakes, reservoirs and other sources of water turbidity less than 3000mg/L, as the main water purification treatment device
2. It has special adaptability to lake water sources with low temperature, low turbidity, and seasonal algae.
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 for the treatment equipment of purified and reused water in the middle water channel system, using the effluent from the sewage treatment plant as the water source.
3、 Main features
1. In addition to the management of the primary 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. Efficient flocculation and sedimentation effects ensure that the effluent quality remains in good condition.
5. The novel and original water collection system and the lowest 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 ensures efficient filtration (when the turbidity of the raw water is less than 3000mg, the turbidity of the filtered water can be maintained below 3mg) and automatic backwashing, without the need for additional backwashing 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. It has a small footprint and can save more than 50% of the land compared to general water purification structures. It has a height of about 4.10 meters and can be installed both indoors and outdoors.
9. Easy to expand, renovate, reuse, relocate or relocate.

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.

Note: 1. The direction of the inlet connection of 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 lowest 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.

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 highest water level in the clear water tank.
