100-10000 Kglink Up Filtered Water Supply System For Rural Waterworks 5-50 Degrees Celsius

Filtered Water Supply System For Rural Waterworks
Ultrafiltration is a membrane separation that uses the microporous structure of semi-permeable membranes to achieve selective separation and recovery of substances with a certain external pressure (0.1 to 0.5 MPa) as the driving force. In a variety of water treatment is mainly used to separate molecular weight greater than 500, diameter 0.005 ~ 10μm macromolecules and colloids, such as enzymes, proteins, viruses, and other low concentration of macromolecules dissolved state and colloidal pollutants in the separation and recovery.


I. Introduction of iron and manganese filter

Groundwater in many areas contains iron up to 5~15mg/L, up to 20~39 mg/L, manganese up to 0.5~2.0mg/L, and even more than 2.0 mg/L. Iron exceeds the standard of groundwater to Fe2+ state exists, so when just pumped up, the water quality is clear and clean, but there is a ferruginous smell. Time is a little long, the water quality is turbid. Fe2+ is very easy to contaminate the ion exchange resin, so that the resin poisoning and reduce the exchange capacity. Fe2+ make the reverse osmosis membrane contamination and failure. Iron-containing water as boiler make-up water, easy to scale, not only affect the heat transfer, but also easy to cause corrosion of the pipe wall. Cooling water containing iron more than 0.5mg / L, iron, will promote iron bacterial reproduction, resulting in slime in addition to clogging the pipeline, but also accelerate the corrosion of equipment. The iron and manganese removal filter collects the processes of oxidation, ion replacement, retention and clarification, and makes a reasonable design process according to the customer's water quality to achieve reliable and stable results.
Remove iron and manganese in 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 of the water is high or low, the choice of jet aeration or hollow multi-faceted ball aeration. Adopting one level or multi-level iron and manganese removal 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.

I. After treatment by iron and manganese removal filter to meet the standard of drinking water
Many towns and industrial and mining enterprises in China use groundwater as water source. However, in many areas, the groundwater contains excessive iron, the content of which is generally in the range of 2-16mg/L. After treatment, the iron content of the groundwater is ≤0.3mg/L, which is in line with the national GB5749-85 drinking water quality standard.

Scope of application of iron and manganese filter
1,It is applicable to the iron removal treatment system in which the iron content of groundwater is ≤8mg/L.
2,It is applicable to the iron removal treatment system in which the iron content of groundwater is >8mg/L-≤16mg/L.
The two kinds of iron removal devices are suitable for medium and small towns, rural water supply, industrial and mining enterprises, industrial water, softening, desalination process and other groundwater as a water supply source of the treatment system.

Unique advantages of iron and manganese removal filter
1. This series of devices are fully automatic. From water inlet, oxygen flushing, water distribution, filtration, backwashing and water discharge and other processes, they are combined into an integrated new iron removal device. All can be automatically adjusted according to the operating requirements.
2. There is 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 special manganese sand filter material with high iron removal efficiency can ensure the water quality and quantity requirements after use.
4. If the electrical control system of high and low water level is set up in the clear water tank and connected with the opening and closing system of the deep well pump, then the whole system can reach the requirement of unmanaged full-automatic water purification and treatment system.

Fourth, in addition to iron and manganese filter design parameters
1. Iron content of applicable feed water: ①≤8mg/L ②>8mg/L～≤16mg/L
2. Iron content in the effluent: ≤0.3mg/L in line with the national GB5749-85 drinking water quality standards.
3. Surface load: 8-9M3/H-M2
4. Flushing intensity: 14-16L/S-M2
5. Flushing time: 4-6mim (adjustable)
6. Inlet pressure: 0.2MPa
7. Filter material: delicate manganese sand 0.5-2mm particle size for iron and manganese removal
8. Working temperature: 5℃～40℃ (special temperature can be customised)

I. Multi-media filter:
This system is to remove suspended matter, particles and colloids in the raw water, and at the same time, it plays a role in reducing the turbidity and chromaticity in the raw water, and it can filter out particles, algae and other visible matter brought by the raw water.
Multi-media filtration is an advanced micro-flocculation filtration method, the company provides multi-media filters containing multi-layer filtration media with different materials, which can filter out impurities insoluble in water and ensure that the SDI value is not greater than 4, and it is a strong protection screen for the latter RO. Can better remove suspended or non-dissolved particles in water (oxides, turbidity, particles, etc.), with low cost, operation and maintenance, easy to manage and other characteristics, especially in reducing the turbidity of the raw water, pollution index, etc. has a very good effect.
Multi-media filter backwash cycle time of 16-48 hours. Backwash to pressure parameter equipment to control the backwash cycle, through the controller for filter sequence timing backwash, running, positive washing process.
Second, activated carbon filter:
Activated carbon process in the field of water treatment occupies a fairly important position, is an indispensable process in the depth treatment of water, which has certain special effects that are irreplaceable by other water treatment processes.
De-colouring can remove the chromaticity formed by iron, manganese and plant decomposition products or organic pollutants.
Dechlorination removes odours caused by residual chlorine.
Organic matter removal
Removes trace pollutants in water that cannot be removed by conventional processes due to water contamination, such as pesticides, insecticides, chlorinated hydrocarbons, aromatic compounds, and BOD and COD.
Organic Chlorine Removal
It can remove THMS and other ‘three causes’ produced by pre-oxidant and disinfectant (e.g. chlorine) in the process of raw water purification and before the water is delivered to the factory. Some analyses show that tap water in the ‘three substances THMS accounted for most of the effective removal of the key to improving water quality.
Removal of ammonia and nitrite
Activated carbon can effectively remove ammonia and nitrite.
It removes residual chlorine or oxidants and protects the cartridges of ultrafiltration and reverse osmosis.
In addition, it can deodorise and remove trace heavy metal ions (such as mercury and chromium ions), synthetic detergents and radioactive substances from water.
III. Softener (scale/hardness removal)
The softener removes calcium and magnesium ions from the water through the action of a strong acid-type cationic resin, so that the hardness of the water is <0.03meg/L (CaCO3), thus reducing scale. The softener uses one stainless steel tank, water production: 3000/hr. This tank is corrosion-resistant, robust and no other substances are released. The control valve is robust, wear-resistant and easy to maintain. This water softening system can be set according to the raw water quality to produce water and regeneration cycle. The water softener is equipped with high-efficiency strong acid cation resin, with uniform granularity, high strength, not easy to wear and tear, and large exchange volume. The salt suction system of the water softener is equipped with liquid level, filtration and automatic water return function, which can effectively prevent the pollutants in the salt tank from entering the softened water system during regeneration and can fully dissolve the regenerant so that the regeneration reaches the saturated state. Widely used in: boiler soft water treatment, solar hot water, heating circulating hot water, chemical industry, breeding and other industries.
