An overview,

   This device including water, reaction, precipitation, filtration, water, mud, automatic backwashing seven main unit,

 built in PPC (ethylene-propylene copolymerization inclined tube packing) inclined tube filler, and various specifications

 refined filter material, equipment for main shell for carbon steel production, the use of special coating inside and 

outside of corrosion, long service life and wide range of application, performance is remarkable, is widely used in large,

 medium and small waterworks construction and retrofit (station).

 Process description

  Before the water pump is driven into the static mixer from the original tank, the water pressure is ≥ 0.07mpa.A static 

pipeline mixer is set up in front of the high-efficiency automatic water purification unit. The water treatment agent 

coagulant (polyaluminum chloride) is prepared in the dosing unit in the pharmacy and pumped to the pipeline mixer by

 metering. The mixer makes the mixture evenly through the shearing and stirring action of its own structure, and then 

enters the water purification unit.

When raw water entering the high efficient automatic water purification device, first enter the device with water, at the bottom of the

 uniform water distribution, water flow rate is reduced, and slowly entered the high concentration of flocculation, a thorough coagulation 

reaction, under the effect of inclined tube diversion area diversion, the flowing water in the inclined tube tilt direction up, enter the 

subsiding area, deposited sludge under the action of gravity, along the inclined tube slipping from the tilt, and slide the alum flowers in 

the diversion of the inclined tube under the action of hydraulic, is pushed to the water purification device inside the bucket, and through

 the inclined tube clarified water is from the upper water purification device to filter indoor, and top-down filtered through filter layer,The

 alum flower in the water is filtered layer interception, filtration.The filtered clean water is collected to the clean water area at the bottom

 of the device through the filter head and returned to the clean water layer at the top of the device by the connecting pipe.The raw water

 is purified in the water purification unit and then flows into the clean water tank.Equipment sludge discharge and backwash sewage 

discharge: the sludge deposited in the highly efficient automatic water purification unit will be automatically removed regularly by the

 sludge discharge system, and the discharged mud and filtered backwash water will be connected to the sewer or mud pit for drying 

treatment.

Mud discharge: after the water purification device runs for a certain period of time, the electric valve will automatically

 discharge mud once through the signal given by the central control cabinet. When the electric sewage valve opens, the

 pressure water impulse valve will also open to help flush.(if the turbidity of raw water is lower than 500mg/L, the mud 

discharge period T=12 hours is appropriate, and the mud discharge period can be adjusted).Backwash drainage, sewage after

 certain time filter layer, and the resistance of the filter layer increases gradually, when the water level rose to a 

certain height, that is beginning to form automatic backwashing, filtered water in the area under the static pressure of 

the upper clear water rapidly accelerate the back flush, water plant in accordance with the normal operation of the path 

back to the opposite direction, when the water filtered area began to back flush filter layer, backwashing after 3 ~ 5 

minutes, when the water level of water area dropped to a certain level automatically stops the flushing.Backwash sewage is discharged into the drain and diverted from the drain to the sewer or mud pit.

performance advantages

1, the water purification device itself from reaction, flocculation precipitation, water collection, water distribution, filtration, 

internal backwash, mud discharge and a series of operating procedures, have achieved the effect of automatic operation, the

 central control cabinet has a PLC interface, as long as the personnel on duty for regular water quality monitoring, there is no

 need to operate and manage the water purification device.

2, high concentration of flocculation layer, can make the impurities in the raw water in the meantime get full contact with the

 collision, the probability of adsorption increases, so it can adapt to the water temperature and turbidity of various raw water,

 impurity particles removal rate is high, under certain conditions of use, also has the function of algae removal.

3. Quick sludge concentration chamber and adjustable automatic sludge discharge system can ensure the timely removal of 

excess sludge, so as to ensure a stable removal rate of impurities and particles.

4. Efficient flocculation and precipitation effect, so that the precipitated effluent water quality has been maintained in a good

 state.

5. The novel and original water collection system and the most economical water collection head make the water collection

 more uniform and effective, which not only improves the volume utilization coefficient, but also makes the water collection

 head very small.

6. The automation of the water purification system not only ensures the efficient filtration of the water purification system 

(when the turbidity of raw water is less than 3000mg/l, the turbidity of filtered water can be kept at about 5mg/l), but also can 

automatically kick back, without the need for additional backwash pumps or air compressors and other electrical equipment, 

nd saves a lot of investment in infrastructure and daily operation, maintenance and maintenance costs.

7. The equipment's water consumption rate is about 3%, which plays a positive role in saving precious water resources.

8, the floor area is small, compared with the general water purification structure, can save more than 50% of the ground, the

 height of about 4.35 meters, indoor and outdoor can be placed.

9. Convenient for expansion, transformation, relocation, or relocation for reuse.

10. The construction period is short, which is one-fourth of the construction period of the conventional clarification and filtration facilities.

11. The height of the water purification outlet is ≥2m. The water purification tank can be built in semi-overground type.
