Disc filter

Disc filter application in developed countries has been quite common, because its can be used in quite a harsh conditions accurately steadily work and need less maintenance is widely used for irrigation, waste water treatment, wastewater regeneration, municipal water supply, water plant, large power plants, chemical industry and contingency filtering, etc.
The disc filter adopts modular design, which can be used in a variety of combinations according to the filter unit to meet the actual needs of different applications. The anti-flushing controller is easy to operate, and can be controlled by the filter or workstation in combination with the pressure difference, time or combination. Laminated filter cartridges are not replaced for 15 years.
Specifications:
Disc filter core parts are stacked together in plastic filter plate, filter plate has a special groove or edge, the groove or neighboring filter plate edge channel constitute a certain size, particle size is greater than the channel size of suspended solids were stopped, to achieve filtering effect. The product can replace the traditional mechanical filtration devices such as sand filter to a large extent, and its performance is superior and water power consumption is far lower than other products.
Disc filter in the filter plate design of the different structure of edges on both sides, the rib added together constitute the interception, the curve edge mainly have the effect of intercepting and store suspended solids, the lateral slightly larger exposure design can ensure that you do not need to loosen the filter plate when backwash, the water pressure is low, also can achieve thorough backwash effect; The loop edge determines the filter precision and forms the water channel. The filter can provide up to 5 mu of filtration precision. When the original water enters the middle of the two strainer, the flow of the curve of the curve is first, but the inspection cannot be directly entered. At this point, the filtering interception is the ring edge, which is less than the size of the ring groove and the impurities can enter the curved edge with the inner edge along the ring edge, and the large impurities are intercepted. Unique structure of the filter plate also makes the dirt out of the washing process is more simple and easy, without the need for a complex institutions such as motors and drives, simple flow can be enough to get dirt out of the filter. This excellent performance reduces the anti-flushing time of the filter. At the same time, because the dirt is not stored between the filter and the shell, more can be stored inside the filter panel, so the filter can hold more dirt.
Technical parameters of Disc filter:
1. Operation parameters
Capacity of 0.25 MPa
The flow velocity of 5 mu ~800 mu is 8~18m3/h
Working pressure 0.08~1MPa reverse wash time 20~60 seconds
Working temperature < 80 ℃ backwashing water consumption 30 ~ 100 kg (single filter head)
PH5 ~11.5 system pressure loss 0.001~0.08MPa
2. Equipment material
Disc filter unit manufactured by reinforced polyamide plastic forming, anticorrosive wear-resisting, can work under pressure 1 mpa, filter plate material for polypropylene plastic EPDM seal, in and out of the water and drain road with carbon steel polyester coating line, engineering plastic and stainless steel three;
Valve has plastic valve or metal valve;
The system provides a multi-function control panel.
3. Filter plate separation
The filter function of disc filter is completed by the internal filter, and the user can choose the filter plate with different precision according to the water requirement. The specifications are 5 mu, 10 mu, 20 mu, 55 mu, 100 mu, 130 mu, 200 mu, etc.
For ease of installation, different specifications of the filter plate with different colors to distinguish, its color, respectively, as follows (filtration precision general requirements in industrial applications in 5 ~ 50 microns, so only a few specifications not listed here) :

4. Combination form
Disc filter is mainly based on disc filter unit to constitute, the classification of the disc filter unit for import and export of pipe diameter, there are mainly 2 ", 3 ", 4 "three categories, respectively in combination to install again have different forms.
2"DY-2~10:2~10 2" filter unit arrangement.
Such as dy 2-5
3"DY-3~10:3~10 3" filter unit permutation combination.
Such as 3 dy - 7
4"DY-3~10:3~10 4" filter units connected together
Application and selection:
A. Excellent water quality: unpolluted urban water, well water extracted from stable aquifer;
B. general water quality: circulating cooling water, poor water quality, surface water treated with precipitation, effective precipitation and complete biological treatment of drainage;
C. Poor water quality: groundwater extracted from aquifers with poor water quality, water drained by effective precipitation, but without or without minimal biological treatment, the surface water with abundant microbial reproduction;
D. Poor water quality: well water with high iron or dirty, water affected by the flood, unprecipitated surface water, more water in the river or other surface water, and untreated drainage.

Classification of original water quality
Good water quality: urban tap water, well water extracted from stable aquifer;
Normal water quality: circulating cooling water, the surface water treated by precipitation, through the effective deposition of complete biological treatment of drainage;
Bad water quality: groundwater extracted from bad water quality aquifers is effectively precipitated, but without or through minimal biological treatment of drainage, there is a large amount of microbial reproduction of ground water;
Worse water quality: well water extracted from a very dirty or iron-rich well, which is affected by the flood and has not been precipitated by the surface water, without precipitation or biological treatment.
