From the experience and study in pretreatment equipment, Toro Equipment has developed a new adjustment system to solid scraping in Defender® Self-cleaning Rotary Screens. With this improvement, the scraper clean process turns into a simple and fast operation to make easier the daily work. The innovative system has been applying in Defender® Rotary Screen TR 40 range and in High Performance Rotary Screen HPS-S range, currently this new upgrade will be included in TR 63 and HPS-M range.
With this system, the scraping of filter drum is auto-regulated with solids remaining. In this way, the scraper retracts, solids are removed and the mechanism returns to its original position. The scraper also can be retracted manually with the ergonomic rod in GFRP to facilitate the cleaning of the specific zone where solid is stuck on.
Importance of pretreatment
Pretreatment, which is the first stage of water treatment process, protects all the following equipment from potential incidents. Specifically/Particularly, the screening defends the equipment (pumping systems, blowers…) and increases their durability and effectiveness. This process, relatively cheap in comparison with subsequent others, improves and protects all the treatment system and reduce part of pollution and COD in waste water.
Advantages of an appropriate screening
- Increase equipment durability
- Improve energy efficiency of following treatments
- Low maintenance cost
- Better effectiveness of the equipment and less issues
- Low cost in relation to more sophisticated equipment
- Can be done in small places
- Not requiring workmanship
- Self-cleaning filter drum
