Well water, groundwater treatment is mainly to remove iron and manganese, ammonia, sediment, scale and other harmful substances, so that the treated water quality meet the national drinking water standards. At present, well water, groundwater treatment mainly iron, manganese, because in our country, the high content of iron and manganese in groundwater is quite common, in addition to iron and manganese mainly aeration plus filtration, filtration filter medium is usually quartz sand, manganese sand, behind then through the activated carbon filter and precision filter, after treatment, water can basically meet the national drinking water standards. The ammonia is mostly used ultrafiltration or reverse osmosis filtration processes, sediment and scale can be multi-media filtration and ion exchange softening filtration device.
Deep well water, groundwater, iron and manganese removal equipment using advanced addition to iron, manganese technology, the well pump and pressure pumping or compressed air filling machine, mixing oxygen perforated pipe, the exhaust valve automatic degassing, the perfect combination of the filter bed DO contact oxidation filtration deep well water, groundwater iron and manganese removal device has a small footprint, the pipe is simple, small investment, stable and reliable performance. In addition to iron and manganese filter is mainly used for domestic water in the removal of divalent iron and manganese, is an ideal addition to iron and manganese equipment.
Groundwater dissolved organic matter on iron and ferric oxide is reduced under anaerobic conditions, so a lot of iron into the groundwater, iron and manganese in the water often exist, our drinking water health standards, the iron content of ≤0.3 mg / L, manganese content ≤0.1mg / L, long-term consumption of iron, manganese high water on the human body adversely, textile, paper making, brewing, food, etc. affect the quality of the items generated spots, and corrosion of equipment, it should iron and manganese removal treatment performed.
Many of the fluorine-containing groundwater, and concentrations exceeding the national standard, if not treated, can not be used as drinking water, because of the high fluoride content of drinking water can cause fluorosis, health effects, ranging from teeth black, spot glaze, enamel loss and early tooth extraction, while causing skeletal deformities and even bone sclerosis. Therefore, in order to protect people's health and protect the environment, our well-developed produce a fluoride device allowing the treated water, the fluoride content of drinking water in line with our standards, that is less than 1mg / l, industrial wastewater treated later, can also be reached industrial waste discharge standards.
二、In addition to iron and manganese equipment works
In addition to iron and manganese device works: the use of oxidation of iron ions in the water cheap and low-priced manganese ions are oxidized to ferric ions and high manganese ions, and then filtered through adsorption removal of iron and manganese content in water to reduce the head. Filter using refined manganese sand or quartz sand.
In water to the presence of Fe2 + state, Fe2 + ions can easily contaminate the ion-exchange resin, the resin exchange capacity decreased poisoning, after heated easily generate the dissolved iron in the heating surface, affect the heat transfer and corrosion of equipment, excessive iron groundwater, or well water, the water smell. Iron and manganese removal equipment, the use of natural manganese sand contains MnO2 and Fe2 + redox reaction, the Fe2 + into Fe3 + and generate Fe (OH) 3 precipitation, using a filter backwash function to be removed.
1．After sparging by iron and manganese sand is filtered, the water oxidation reaction of divalent iron in the filter layer can be quickly completed, and while the iron trapped in the filter layer, thus completing a full iron removal process.
2．After sparging manganese manganese sand is filtered through that high manganese hydroxides gradually attached to the filter surface, forming a contact with a catalytic manganese filters, allowing the water divalent manganese is oxidized to remove high manganese .

1.Outline
Lee hit a 32 m deep well. Well lay next morning, he found that out of the water last night, new darker, the "yellow" and exudes stench. He instinctively think there is a problem of water, "undrinkable." In Shenzhen, the son of a doctor told him that the tea into the water, you can verify whether the toxic well water. Lee was so surprised after the ordinary green tea into the water, like a magic-like, less than three minutes, colorless bowl of water is "dyed" became purple.
2.How siting wells?
In season water stress, water wells has become an important measure to solve the water problems of the people. Professionals said drilling site should consider various criteria. If you want large amount of water regardless of the water quality, water well location to be close to water sources; to try to avoid the existing wells, in order to avoid mutual interference water, causing the water is reduced. If you want good water quality, consider avoiding pollution. Also, consider the well production and living away from the venue, away from livestock pens, the pit 30 meters or more away from industrial pollution.
3.Why should I use well water (ground water, river water, etc.) processing equipment?
China has abundant groundwater resources, many of which contain excessive groundwater sources of iron and manganese, iron manganese called groundwater. When the high iron content in water, the water has iron smell, affect water taste, as the paper, textile, printing and dyeing, chemical and fine leather and other production water, will reduce the quality of products; iron water make household appliances such as porcelain basin and bathtub rust occurs, wash the clothes will appear yellow or brown stain stains; Fe2O3 iron precipitate iron bacteria will grow, blocking the pipes, sometimes red water.
The problem occurred high manganese content of water and the high iron content in a similar situation, for example: water colored, smell, taste, compromising quality textiles, paper, brewing, food and other industrial products, household appliances will pollute a brown or black, washing clothes or light gray spots have blackish stains. This country "drinking water health standards" (GB5749-85) provides, iron, manganese concentration should not exceed 0.3mg / L and 0.1mg / L respectively, than the standard raw water is subject to removing iron and manganese treatment, the quality of raw water to reach national water standards.
4.How should we well water (groundwater, river water, etc.) to effectively deal with it?
4.1Flow Chart:
Raw water (groundwater / river water) → sedimentation tank (aeration (blowers) / dosing (alum, PAC)) → → Multi-media filter booster also mechanical filters (filter: quartz sand (2- 4 mesh / 4-6 mesh) / manganese sand / SS filter) → activated carbon filter (filter: coconut shell carbon / husk carbon / carbon from coal) → water points (up to the national water standards).
4.2Process Description:
Sedimentation tank role is mainly to extend water iron and manganese ions and oxygen ions in the air a chemical reaction time, generating three iron / manganese dioxide precipitate.
Booster function mainly on raw water pressure, the system provides a power source; light horizontal multistage centrifugal pump with a mechanical seal exemptions. Pump flow components are made of stainless steel (304 or 316) made with low noise, light corrosion resistance, beautiful appearance, small size, light weight, long service life.
Multi-media filter main role is in the role of a catalyst (such as manganese sand / SS filter / aeration / dosing, etc.) will be dissolved state of divalent iron or divalent manganese were oxidized into insoluble ferric or four divalent manganese compound, and then by the multi-media filter to be removed. Raw water before entering the multi-media filter, efficient flocculant dosing to more thoroughly prolapse and colloidal organic matter in the water and other impurities. In normal use, water flow rate 12m / h, multi-media filter output 0.8m3 / h.
Activated carbon filter main role is refined yeah shell activated carbon for the adsorption of water Harmonia raw water, odor, chlorine, chlorine byproducts and organic matter, some pigments and harmful substances (such as pesticides, insecticides, chlorinated hydrocarbons, aromatic compounds), reducing chemical oxygen demand COD. Activated carbon is widely used in domestic water purification and food industries, chemical and other industrial water, due to the large surface area of activated carbon, the surface has covered an average of 20-30 Å pores, therefore, activated carbon has a high adsorption capacity.In addition, the surface of activated carbon has a large number of hydroxyl and carboxyl functional groups various properties of organic materials for chemical adsorption, as well as the role of electrostatic attraction, therefore, activated carbon can remove humic acid, rich dimension acid, lignin sulfonic acid, etc. organic substances, but also to remove residual chlorine as a class of substances harmful to the reverse osmosis membrane, typically capable of removing 63% -86% colloidal material, about 50% iron, and 47-60% of organic substances. Activated carbon prolapse chlorine process is a simple redox process. This process has the potential to charcoal broken, but broken activated carbon does not affect the effect of chlorine prolapse, prolapse therefore charcoal chlorine effect is very strong.
