How do competing filter types stack up to automatic, self-cleaning water filters?
A Tekleen water Filter not only saves you time and money replacing cartridges ands bags by automating the cleaning cycle, but is also more advanced and cost-effective than other water filter options available. Below are some of the many advantages automatic filters offers over sand media filters and hydrocyclone separator filters.
|Tekleen Automatic Filter||Sand Media Filter|
|Filtration Technique||Physical - Stops particulates larger than mesh opening, ignoring small particulates that can safely pass through the system.||Statistical - Stops small irrelevant particulates. Sensitive to high dirt load of particulates.|
|Cleaning Mechanism||Focused backwash. Cleans the entire screen area 100% from impurities. Uses 80 gallons per backwash for a 1,200 GPM single water filter.||Impossible to ensure 100% cleaning of the sand media from impurities. Uses 4,000 gallons per backwash for 1,200 GPM (4x48" tanks).|
|Medium Stability||Screen kept stable at all times.||Sand must "float" during backwash. Sand will not return to original compacted state. Sand channeling occurs.|
|Installation||Easy to install in any position.||Requires concrete platform, pipings, electric power, etc.|
|Maintenance||Virtually maintenance free - easy to dismantle.||Internal maintenance laborious and costly.|
|Cost||25% less than sand media filters|
|Tekleen Automatic Filter||Separator/Hydrocyclone Filter|
|Positive Filtration||Physical - Stops particulates larger than mesh opening and separates the dirty side from the clean side of the filter (inlet from outlet)||There is no true barrier between the inlet and the outlet of the filter. Due to flow changes, dirt will pass through. Result: dirt in system and plugged spray nozzles.|
|Absolute Filtration||Focused backwash. Cleans the entire screen area from impurities. 100% efficient in particulate removal.||Not 100% absolute filtration. It is "separation" and is determined by the velocity of the water and dirt load.|
|Organic Matter||Screen filter will remove 100% of all organic matter from water including pulp down to 10µ.||Will not remove organic matter since it is lighter than water.|
|Inorganic Matter||Screen filter will remove 100% of all inorganic particulates down to 10µ.||Can remove only up to 98% of dirt load if the dirt is 75µ and larger. Result: clogged spray nozzles.|
|Pressure Usage||Uses approximately 2-3 psi.||Uses approximately 10-15 psi.|
