Screw Screen

Product Details

The Screw Screen / Spiral Screen combines screening, conveying, dewatering and solids discharge in a single machine. It operates automatically in an enclosed system, helping reduce the volume and moisture of the waste as well as odour and contact. It is suitable for use as a preliminary screening device in wastewater treatment systems.

Key Features: Screw Screen
  • Combines screening, conveying, dewatering and discharge in a single machine
  • The conveying screw helps reduce the volume and moisture of the waste
  • Enclosed system helps reduce odour and dispersion
  • SUS304 stainless steel structure, strong and corrosion resistant
  • Fully automatic operation, easy to maintain
Benefits: Screw Screen
  • Reduces the volume and weight of debris sent for disposal, saving disposal costs
  • Reduces odor and hygiene issues thanks to the enclosed design
  • Substantially reduces labor for headworks debris handling
Working Principle: Screw Screen
  • 1. Wastewater flows through the screen, which captures the solids.
  • 2. The screw conveys the captured debris up through the machine body.
  • 3. Debris passes through a compaction zone where water is pressed out and volume is reduced.
  • 4. Dewatered debris is discharged at the end of the machine into a bag or container, while the pressed-out water flows back into the system.
Supported Industries
  • Municipal and industrial-estate wastewater treatment systems
  • Food and beverage plants
  • Slaughterhouses
  • Headworks applications that need solids capture with debris volume reduction in a single machine
Product Highlights
  • Combines screening, dewatering and waste discharge in a single machine
  • Reduces both the volume and moisture of the waste, helping reduce the disposal burden
  • Enclosed system helps control odour and reduce contact with the waste
  • Fully automatic operation, reducing labour

Static Screen

The Static Screen / Wedge Wire Screen is used for preliminary wastewater treatment, using gravity to separate solids from wastewater without electricity and with no moving parts. It is made of SUS304 stainless steel wedge wire screen, with selectable slot openings of 0.25–3.0 mm, supporting a maximum flow rate of approximately 270 m³/hr. It helps reduce TSS and protects pumps and valves in the treatment system.

Rotary Screen

The Rotary Screen (External Fed Rotary Drum Screen) is a rotating drum screen for continuous and automatic separation of fine solids from wastewater. It uses a stainless steel wedge wire screen with openings of 0.25–3.0 mm, supports wastewater with high oil or grease content, and comes with a scraper blade and water spray system to help reduce clogging.

Internal Drum Screen
PRE TREATMENT

Internal Drum Screen

The Internal Fed Rotary Drum Screen is a high-efficiency drum filter in which wastewater is fed from inside the drum and separated to the outside, providing gentle flow that reduces the break-up of flocs and fragile solids. The screening basket is inside and the structure is entirely stainless steel, designed with a tightly sealed cover so odour can be controlled. It is suitable for wastewater containing soft or fibrous solids.
