Functions & Applications
Filtration equipment mainly used in water purification, especially in higher quality of micro-filtration field. The main feature of the filtration equipment is to wipe off sand, clay, rust, suspended solids, algae, biological fouling, corrosion product, the macromolecule bacteria, organic matter and other small particles, oil etc., and achieve the water purification. |
|
| |
| Technique & Features |
| • |
High filtrating accuracy, stable water quality and supply. |
| • |
With its own search and emergency operation function, making automatic back-washing, and can cope with volatile fluctuations without people’s operation. |
| • |
Filtration equipment control system is responsive and have a precise operation, can adjust back-washing pressure setting according to different sources and filter accuracy in a flexible way. |
| • |
High efficiency and completely cleaning, and the system has a strong recovery, the cartridge can be used permanently without replacement. |
| • |
During the back-washing, each cartridge operating in turn, to make sure cartridge completely clean, and meanwhile the other cartridges not being affected and keeping on filtration. |
| • |
Using drain valve, which lasted a short-back-washing, less water consumption, save water, power and energy source. |
| • |
Reasonable and compact structural design, small occupational area, installs and removes flexibly, conveniently. |
| • |
Less fragile equipment, no consumable material, low operation and maintenance cost, simple operation and management. |
| • |
Widely being used, suitable for different raw water quality and water requirements. |
|
| |
| Technical Creation |
| • |
Using SS304 wedge cartridge, strong strength, high accuracy, corrosion resistance, the micro rating can be up to 25 µ m. |
| • |
The internal mechanical structure with patented technology achieve a real sense of the high-pressure back-washing functions, which can remove impurities from cartridge easily and thoroughly, cleaning without a corner, no flow decay and protect the filtration efficiency and long life. |
| • |
Inlet and outlet flange design can adjust the direction of rotation arbitrarily, convenient for installation on site. |
| • |
Electrical system adapts an integrated control mode, which can achieve the remove control. |
|
| |
Process Description
When liquid flows from inside to the outside, contamination particles than collect on the smooth inside of cartridge and the contamination increases the differential pressure between the contaminated and clean side of the filter increases. When the differential pressure reaches its pre-set value, the differential pressure indicator send a signal than the filter start back-washing automatically. |
| |
| Back-Washing |
| • |
The gear motor turns the washing arm through the middle rotation, the photoelectric sensor controls washing arm running angle so that the cartridge being cleaned. |
| • |
The drain valve is opened, which results in a pressure drop between the drain valve and filtration side. |
| • |
With the pressure drop, fluid flows outside to inside to backwash, the contamination particles collected on the inside of the cartridge are loosened and washed out the filter. |
| • |
A typical back-washing time has been set, as soon as the “back-washing time per cartridge” has been elapsed, the drain valve is closed, a back-washing of this cartridge is terminated. The gear motor turns the washing arm again to backwash the next cartridge, the drain valve be opened again, and so on for each cartridge. |
| • |
All the cartridges are flushed in succession and have been cleaned, the washing arm backs to the original position, a back-washing cycle is terminated. |
| • |
Because for each cartridge back-washing, the filtrate flow is not interrupted during the back-washing procedure. |
|
| |
| Back-Washing Setting |
| • |
Pressure drop setting: There are two set points in the differential pressure indicator of the filter, the first point for back-washing process, the second point for monitoring working process, optional by customers. |
| • |
Time setting: With a time device on PLC to set “back-washing time per cartridge” cycle according to customer’s request. |
| • |
The two settings both exist, and pressure drop setting is in priority. |
| • |
Manual Start: When the TEST key is pressed, the filter starts to regenerate the cartridges, which can be used in debugging and overhauling. |

Automatic metal-edge filter |

Structure & Working Principle
Filter concept automatic metal-edge filter contains gear motor reducer, housing, cartridge, scraper filter system, PLC controller, draining valve and so on.
The medium to be cleaned is guided into the filter by inlet, passing from inside to the outside, through the cartridge gap. After filtrating the filtered fluid exits the filter housing at the top opposite the inlet connection, the bigger solids are separated on the surface of the triangular cartridge wires. When it runs a certain time, the cartridge gap will be plugged up by impurities, and meanwhile the differential pressure reaches the pre-set, and then PLC inspects signal and sends out the indication. The gear motor drives the scraper, the particles or agglomerates are skimmed from the surface, thereby, keep the function of cartridge well, keep the cartridge gap clean, When the impurities of the bottom of filter increases, just open the drain valve, the impurities will be emptied successfully, and make the system pressure keep normal, Because of reasonable positions and optimum scraping angle of the filter’s scrapers, the rotational scraper drain off the impurities from the filter clearance timely by the gear motor, which avoids the burden of taking down and washing the cartridge, thereby, make the medium being filtered successfully. The scraper system contains stator, PTFE scraper and spring, which are designed for automatic cleaning, and especially for the reasonable spring pressure, maximally reduce the cartridge’s abrasion. |
| |
| Design Feature |
| • |
Using automatic continuous on-line filtration, meet the automation operation request. |
| • |
System drives by motor, the gear motor runs against the spring actuated scraper, the concentrated solids are drained off simply by the system, and keep the function of cartridge well. |
| • |
PLC control function means differential-pressure cleaning, time preset time cleaning, manual cleaning. The differential-pressure is in priority, and be connected with the central control room. |
| • |
Validated by practice, the effect of filtration is very nice, and using the wedge cartridge, easy-cleaned, less abrasion. |
| • |
In many fields, this filter can replace the traditional bag filter, basket filter, cartridge filter, vibratory sieve filter, frame filter, strap filter and so on. |
|
| |
| Applications |
| • Industrial cycle water such as iron and steel blast furnace, rolling mill, cast machine, condensate, cooling water. |
| • Water filter such as desalination, river water, surface water. |
| • Environmental engineering such as the pre-filtration of bag, cartridge, UF, RO membrane etc. |
| • Paper making industry such as white water, original water, nozzle protection. |
| • The filtration of central air condition system, petrochemicals, automobile. |

Working Principle
Using a spring-loaded cleaning disc travels up and down inside the filter screen, removing collected contaminants. The filtrate flows from the top to the down, and from the inside of the screen to the outside. The contaminants trapped on the screen for easy removal and evacuation to the collection chamber. On the downstroke, any remaining contaminants are driven downward to the collection chamber. On the upstroke, the cleaning disc removes contaminants from the screen surface. System fluid flow washes the contaminants downward toward the collection chamber past the cleaning disc. |
