Bernoulli water filter

 

 
Brief introduction

 

Brief introduction of Bernoulli filter
 Efficient backwash filter, By linear reciprocating efficient mechanical way to automatically remove particulate impurities on the filter element surface.capable of continuous in-line filter, efficient backwash filter accuracy range is in 100-3000 micron, fit for water and viscous liquids filtered, for viscosity up to 30,000 CP.
When conventional backwash filters soft impurities in viscous material is frequently clogging, customers are forced to choose large backwash filters or frequent backwashing, large investment, heavy workload, a serious waste of materials.Efficient backwash filter with advanced self-cleaning relocation way to easy solve this kind of problem, and always maintain regular clean filter element and discharge high attempt waste impurities to reduce material waste, great advantage of poor water quality water filtration and adhesives, resins, polymers, paints, oils and other viscous materials, more efficient, efficient backwash filter is its significant technological advantage and high life cycle cost, gradually replacing the traditional manual backwash filter in many areas, shaker, bag, basket filter, some recoil type self-cleaning filter and so on.

 

Working principle

 

Bernoulli filter Working principle
Filtering state: Liquid from the efficient backwash filter inlet injection, from up to down flow, through the filter element surface to flow outlet; When the filter element surface collect to a certain impurities, fixed time or set pressure tp started cleaning procedures.
Cleaning state: cylinder drive wash plate to straight action, this part of the impurities with the descending liquid through washing dish to fall into the collection chamber, to repeat washing several times to clean the filter element.
The most important part of the filters, that provides quite simple and reliable cleaning process, is a disk which is installed on pneumatic cylinder. When a disk, placed on pneumatic cylinder's end, passes between water and filter basket, filter basket is cleaned with this movement of the disk. Flow speed of the water increases on the points around the disk and static pressure decreases pursuant to Bernoulli principle
Low static pressure creates vacuum effect on edge points of the disk and contaminants are discharged from the drainage line by being cleaned from the filter basket.

 

Bernoulli filter Operation Steps
Normal Operation: Water comes in through filter inlet and flows into filter basket as 90o for big particles to be decomposed. Clean water is discharged from the outlet. Washing valve is closed in this status and motionless out of the piston filter basket. (Figure 1.1)

Washing step-1: Filter is self-cleanable with the washing of the basket. Washing can be carried out manually, with time or pressure change control method. Washing valve is pneumatically turned on initially and wide parts, which hold on to the filter basket, are cleaned. In the meanwhile, outlet of the filtered water is not divided. (Figure 1.2)
Washing step-2: Washing valve is on in this step. It moves for two times through filter basket by pneumatic movements with piston disk. In the meanwhile, the water passes in a way preventing a friction loss in disk and basket. Flow speed increases around the disk and static pressure decreases pursuant to Bernoulli principle. Low static pressure, occurring around the disk, helps basket to be cleaned and released particles to be discharged. Clean water outlet is on in the meanwhile. After washing process is completed, washing valve is turned off and normal operation is continued. (Figure 1.3)

 Bernoulli filter Advantages
1.Easy maintenance and high operation reliability thanks to a simple and smart cleaning.
2.system with a part, moving a little bit.
3.Stable and low pressure loss both in clean and dirty conditions.
4.Need for low washing pressure to 0.3bar.
5.Easy installation: Bernoulli filters can be carried by pipe installation, on which they are installed. Filter can be installed horizontally and vertically.
6.PVC or glass fibre reinforces polyester body material provides high corrosion resistance particularly in sea water applications. Stainless steel bodied filters can be used in fresh water applications.

Mechanical Installation
Cover:
Cover and body can be installed in an opposite way of the shipment due to the requirement on transfer opening. Initially; it is recommended to install the body without cover. Before being installed , check if loose matters or connection lines are available in the filter.

Gaskets: Gaskets shall be carefully tightened for PVC and GRP flanges. GRP flanges generally require pre-tightening
Position:Filter can be installed in any way as seen on Fig. 1b. Nevertheless; filter body, connections and differential pressure switch shall be horizontal to prevent air accumulation and contamination in air tube. Filter shall be installed in a way it would possess positive pressure downwards to the pump, as shown on Fig. 1c.

Supports: Filter is can be connected directly or in a way it is supported by pipe connections or pipes.
Control Board: Position of the control board shall be in sight of the filter
