< r> Groundwater iron and manganese removal equipment
Working principle
:
After the groundwater containing iron (manganese) is aerated or added with oxidant, the iron (manganese) in the water will ) ions begin to oxidize. When water flows through the manganese sand filter layer, contact oxidation reaction, biochemical effects on the surface of the filter material, and physical interception and adsorption occur in the filter layer, causing the iron (manganese) ions in the water to precipitate and remove. Especially in the process of treating micro-polluted manganese-containing groundwater, iron bacteria can not only effectively remove iron and manganese, but also use ammonia in the water as a nutrient source to perform metabolism. With the participation of other bacteria, they can simultaneously achieve the effect of removing ammonia nitrogen.
Using the interception and filtration effect of multi-media filter materials to remove large-size impurity particles, colloids and suspended solids, it has the characteristics of low-cost operation and maintenance and convenient management. Quartz sand, anthracite, manganese sand, activated carbon, etc. are commonly used as filter materials. They have high filtration speed, large sewage interception capacity, and long filtration cycle. The tank is made of fiberglass, carbon steel, stainless steel, and can be equipped with multi-way valves or electric, pneumatic and hydraulic valves for control. It is suitable for small, medium and large flow conditions respectively, and can realize automatic and manual dual control. The highest filtration precision can reach microns.
Product features of groundwater iron and manganese removal equipment
Unique< r>multi-filter chamber structure
can realize online backwashing (filtration, sewage discharge and backwashing at the same time).
Energy saving: The outlet water is directly supplied to the pipe network, and there is no need to set up a secondary water supply system. It has its own backwash function and does not need to set up a backwash pump.
Water saving: This equipment adopts plum blossom type water distributor to shorten the distance between the filter layer and the water distribution pipe, which can save a lot of backwash water.
Process standards for groundwater iron and manganese removal equipment
Incoming water source: groundwater well water.
Output water quality: domestic water, no color, no odor, meeting domestic water standards.
System configuration: well water self-priming pump, aeration device, sedimentation tank, raw water booster pump, iron and manganese remover, activated carbon filter, purification pool.
System water production rate: %.
The well water in the aeration device enters the < r>aeration device
after being pressurized by the self-priming pump. It is mainly The well water is fully contacted with the oxygen in the air and uses the oxidation method to oxidize the low-valent iron ions and low-valent manganese ions in the water into high-valent iron ions and high-valent manganese ions, thereby rapidly precipitating them. The well water after oxygenation in the sedimentation tank reaches the sedimentation tank for sedimentation. (It mainly plays a buffering role, allowing the water to have enough time to settle) The precipitated clean water is pressurized by a booster pump and then enters the iron and manganese removal system, which mainly removes sediment, rust, manganese, red worms, algae, and some metal substances in the water. For solid matter such as suspended solids, the normal operating conditions of the system are as follows: the operating pressure is, and the average filtration speed is/r.
When the iron concentration in the groundwater is ~/ and the manganese concentration is ~ /, or when the groundwater only contains iron but no manganese, and the iron concentration is around /, aeration - single stage can be used Iron and manganese removal filtration.

If the iron and manganese content in the groundwater is relatively high, that is, when the iron is greater than / the manganese is greater than /, it is appropriate to use aeration - two-stage iron and manganese removal filtration.
