Technology Profile

Dong Yang Water Technologies Co., Ltd. has specialized design, manufacturing, installation and maintenance for water and waste-water treatment facilities. We made steady effort to manufacture and supply the most economical and efficient water treatment equipment. We have been assessed and complies with quality assurance requirements of ISO 9001 and 14001.

The SCRAP-VAC (Suction type Sludge Collector) is an innovative device with a structure that sucks sludge during operation (forward & backward) and discharges it through a hose (such as a vacuum cleaner) without the need for a sludge discharge hopper.

Improvement of Existing sludge collector demerit
  • Sludge bridge and rabbit hole phenomenon. 
  • Collector Driven Load phenomenon by sludge jamming. 
  • Aggravation of treated water quality by sludge decomposition and re-suspension phenomenon
Scraper for sludge collection
  • Scraper application to 900 bending shape 
  • Direction change of scraper depending on movement direction(900 switch)


Sludge discharge facility and method
  • Discharge of sludge by using head(water level) difference based siphon or self priming pump 
  • Sludge collector and discharger are built in one system.
Sludge removal capacity
  • Sludge collected efficiently based on process operation.
  • Automatic control of operating speed and sludge discharge.
  • Sludge in front and back side of scraper is discharged efficiently from sludge suction pipe.
Advantages of application
  • Sludge discharge hopper & valve not required → Reduction of initial project cost
  • Existing type of sludge collector applied by substitute facility → Improvement of moisture content and effluence problem
  • Facility miniaturization by small collection, small discharge method → Increase of price competitiveness through cost reduction
  • Reduction of subsequent process load by control of effluence quantity → Efficiency increase of concentration process and dehydration process
