Whitewater recovery
Whitewater sieve

 White water recycling treatment options


  Under the circumstances to provide your company requirements are as follows: treatment by mesh and felt out of the wash water network, filter out impurities in the Whitewater wash mesh used, thereby saving water and energy conservation. Recommend scouring cloth with water or, more secure. Our Whitewater sieve it available treatment (detailed process flow, see drawings), to remove impurities in the back with white water, saving water, energy saving.

  Model quotation we choose WL-g800-4S Whitewater sieve, using 250 mesh, 61 micron aperture processing capacity of about 250-300 tons / hour.

  Very pleased to work with you on this project, there are problems, please contact me.


  Thank you!

  Whitewater Filter Profile


  Xuridong mechanical Whitewater sieve for solid-liquid separation . It uses high velocity , centrifugal filter to remove fine mesh sieve pore diameter larger than particulates , are not affected by the particle density. Into a single machine head is 3.048 m . After the water reaches the level of the center of the cloth into the water pipe , and then sprayed through a nozzle in a direction tangential to the inner surface of the rotating screen to form a series of overlapping film . Low enough centrifugal force generated by rotation of the screen at a high flow rate through the white water closure screen and fibers. Closure concentrate slipped along the inner wall of the screen . Continuous rotation of the centrifugal screen , high water pressure , angle of rotation of the screen along the external spray can help concentrate rinse slide . Screen rotation angle along the outside of the spray rinse several times per second , in addition to assisting concentrate slipped , but also as a high-pressure backwash water to clean each sieve . Can replace the sun East Whitewater Whitewater sieve processing machinery backwash water as water . Screen speed and the speed of the water spray nozzles combined make Xuridong mechanical closure Whitewater sieve sieve pore size less than some of the particles . So as to achieve the white water recycling, saving water , improve quality and reduce costs.


  Whitewater usually Xuridong mechanical sieve structure material is 316 or 304 stainless steel , stainless steel internally .

  Xuridong sieve size range of 100-325 mechanical sieve Whitewater . Specific number depends on the fiber length and Whitewater Whitewater requirements for reuse . Usually made ​​of stainless steel mesh , but the selection of the synthetic material .

  Retention rate

  Whitewater Xuridong mechanical sieve has two exits , one for the filtered white water discharge , a discharge entrapped fibers or said concentrate. Closure rate is defined as the amount of white water and filtered concentrate ratio . For example , 90/ 10 that enter the SWECO ® Whitewater Whitewater sieve in an amount of 90 % of the filtrate , 10% of the concentrate . Depending on the kind and amount of retention mesh sieve and suspended solids in the white water of the selected change . Low fiber concentration (50-300ppm) when the retention rate of 90/10 - 95/ 5 . Fiber concentration increases, increasing the proportion of the concentrate . Coarse sieve concentrate produced less than a fine sieve . The concentrate may be diluted to a slurry for white water system .


  Xuridong mechanical Whitewater screen in many ways , such as areas of energy , water, fiber, chemicals and sewage treatment can reduce costs and improve product materials will . In addition to reducing maintenance downtime resulting in reduced production losses, largely the result of cost reduction that is shorter payback period , in fact , many users can be purchased only half Xuridong mechanical sieve Whitewater cost recovery .

  Satisfied with the service

  Xuridong mechanical application engineers will help you analyze your Whitewater , understand the requirements of your entire system , designed for your best solution. Problems encountered when running , they will be ready to serve you.

Three , WL-g800-6S Whitewater filter main features


1, the water used in the pulping process , to provide the quality of the pulp.


2, the closed-loop system, to achieve energy savings , fiber recycling ; reduce emissions ; improve machine operating temperature increased production .


3 , a single machine maximum processing capacity of 700m3 / h.


4 , without affecting the normal processing of water fluctuations.


5 , do not plug design .


6 , high solids removal .


7 , low maintenance .


Fourth, the principle and function WL-g800-6S white water filtration machines


Whitewater large flow filter for solid-liquid separation , which uses high-flow , centrifugal filter to remove fine mesh sieve pore diameter larger than the suspended particles , is not affected by the particle density. Water pressure at high flow filter Whitewater probably 0.25 to 0.6 kg or 4.0 ~ 4.5m high box can be. Influent passes through the center pipe into the water reaches the level of the cloth , then sprayed through a nozzle in a tangential direction to rotate the screen on the inner surface, forming a series of overlapping film , low enough centrifugal force generated by rotation of the screen at a high flow rate through the white water trapped under the screen and the fibers slide along the concentrate entrapped inside the screen . continuous rotation of the screen centrifugal , high pressure water , the concentrate itself, gravity , external rotary screen ( back spray pipe , the back pressure of 7 to spray pressure of 13.5 kg ) in a certain spray angle of the washing water can help concentrate fall.


External rotation of the screen along the spray angle is always carried out , not only can help slide the concentrate , but also as a high-pressure cleaning backwash water always makes each mesh sieve Whitewater Whitewater large flow precision can be replaced with water after the treatment used as the backwash water.


Screen speed and the speed of the water spray nozzles combine to make the large flow of precision Whitewater filter mesh aperture diameter larger than a lot of trapped particles and fibers , although not specifically for drying mesh aperture sieve to remove fibers and less than filler, but due to the rotation filters and screens inside and outside the spray machines are tangential way , so the screen can still be smaller than the screen size of the aperture closure of some particles , they still have some for removal , Whitewater thus treated can be safely used for a variety of these spray ( high / medium / low ) , does not cause clogging of the nozzle clogging and other aspects .


After a great deal of water flow precision Whitewater again be used, greatly reducing the mill 's water supply , reducing the consumption of water , but also reduce the discharge of wastewater .
