In addition to iron, manganese filter filter material using manganese sand, anthracite and quartz sand. The main filter material is manganese sand, quartz sand and gravel as the cushion. It is mainly through the adsorbent catalytic oxidation of manganese sand, removing the equipment of manganese and iron ions in the water. It can be designed as manual and automatic control mode, which can be switched between each other. The automatic control system monitors and controls all operation points and process control points, and the operation can realize unattended and fully automatic operation. The system adopts air water backwash and backwash wastewater is discharged.
Equipment overview:
In addition to iron, manganese filter filter material using manganese sand, anthracite and quartz sand. The main filter material is manganese sand, quartz sand and gravel as the cushion. It is mainly through the adsorbent catalytic oxidation of manganese sand, removing the equipment of manganese and iron ions in the water.
It can be designed as manual and automatic control mode, which can be switched between each other. The automatic control system monitors and controls all operation points and process control points, and the operation can realize unattended and fully automatic operation. The system adopts air water backwash and backwash wastewater is discharged. The system design mostly uses concentrated water of reverse osmosis system for backwashing, which improves the utilization rate of water.
When the filter is backwashed, automatic backwashing can be realized through the backwashing time interval set by the upper computer or backwashing can be carried out according to the pressure difference set value at the inlet and outlet of the filter.
The operation modes of the filter include water production, water backwashing, air backwashing, forward washing, etc. All the operation modes run automatically according to the set program.
Advantages of the device:
1. Effectively remove suspended matter and algae and other organic matter in raw water, reduce the turbidity of raw water.
2. Can effectively remove the colloid in the raw water, remove iron, manganese oxides in the water.
3. Uniquely uniform distribution of water, so that the filtration to achieve the maximum effect, can long-term meet the follow-up device for iron, manganese and turbidity requirements.
4. Backwash device with air scrubbing, strong ability, short time, low water consumption.
5. The use of high quality ABS or stainless steel water cap, packing selection of high quality filter material, in order to ensure good filtration effect, and will not appear the phenomenon of backwash mess layer.
6. The device is equipped with inlet and outlet pressure differential switch, automatically realizes automatic backwash according to the set operating pressure differential value.
7. The system design adopts the concentrated water of the follow-up device for backwashing, which improves the utilization rate of water.
Operating conditions:
Inlet iron, manganese content: 5-15mg/L
Suspended substance in water: < 20mg/L
Water iron 0.3 mg/L
Manganese water 0.1 mg/L
Scope of application:
Mainly used in drinking water and industrial water containing a small amount of iron, manganese pretreatment stage.
