Many towns and industrial and mining enterprises in China use groundwater as water source. But in many areas of groundwater contains excessive iron, its content is generally in the range of 2-16mq/L." Automatic iron and manganese filter" overcomes various problems caused by human operation, backwashing, etc., and gives better play to the characteristics of fully automatic work, thus it has the incomparable superiority of other iron removal devices, and the iron content of treated groundwater is ≤0.3mg/L, which conforms to the national GB5749-85 quality standard for domestic drinking water.
The iron content of the treated groundwater is less than 0.3mg/L, which meets the national GB5749-85 standard for drinking water.
Iron and manganese removal in the water must be aeration, the oxygen in the air so that the bivalent iron, bivalent manganese oxidation, generating Fe (OH) 3, MnO2, according to the iron and manganese content in the water is high and low, the choice of jet aeration or hollow multi-faceted ball aeration. Adopting one level or multi-level manganese sand filter, it can meet the processing requirements, and the iron content of the water is 0.3mg/L, and the manganese content is 0.1m/l, which is in line with the national standard of drinking water.
Second, the town automatic iron and manganese filter design parameters
1, applicable to feed water iron content: ① ≤ 8mg / L, ② >8mg / L ~ ≤ 16mg / L
2, iron content in the water: ≤ 0.3mg / L in line with the national GB5749-85 living drinking water quality standards
3, surface loading: 8-9M3/H-M2
3, the surface load: 8-9M3/H-M2
3, the water can meet the requirements of treatment, and can also meet the requirements of treatment. /H-M2
4, flushing intensity: 14-16L/S-M2
5, flushing time: 4-6mim (adjustable)
6, inlet pressure: 0.05MPa
7, filter material: delicate iron and manganese removal of manganese sand 0.5 ~ 2mm particle size
8, working temperature: 5 ℃ ~ 40 ℃ (special temperature can be customized)
8, working temperature: 5 ℃ ~ 40 ℃ (special temperature). (Special temperature can be customized)
Three, the town's automatic iron and manganese filter unique advantages
1, automatic iron and manganese filter are full-automatic operation. From the water inlet, oxygen flushing, water distribution, filtration, backwashing and water discharge and other processes, combined into an integrated new iron removal device. All of them can be automatically adjusted according to the operation requirements.
2. No need to equip suction device, air compressor, backwash pump or water tower. Not only saves the project investment, but also for the project operation and management, maintenance and other work has brought a lot of convenience.
3, the use of high iron removal efficiency of the special manganese sand filter media, can be used to ensure that the water quality and water requirements.
4, if in the clear water tank set high and low water level electrical control system connected with the deep well pump opening and closing system, then, the whole system can reach the unmanaged full-automatic water purification treatment system requirements.
Full-automatic iron and manganese filter scope of application
The iron and manganese filter is divided into two series: one is applicable to groundwater iron content of ≤8mg/L in the iron removal treatment system. The other is applicable to the groundwater iron content >8mg/L-≤16mg/L iron removal treatment system. The two kinds of iron and manganese filters are applicable to medium and small towns, rural water supply, industrial and mining enterprises, industrial water, softening, desalination process, etc., with groundwater as the source of water supply in the treatment system.
