Cylindrical Screen for OUTSIDE INSIDE Filtration

External circumferential wire and axial internal support rods.

  • Economical and suitable for most application
  • Precision opening
  • Application : Filter cartridges / Diatom candle filters / Header laterals / Rotating drum screens / Nozzles / Resin Trap

Cylindrical Screen for INSIDE OUTSIDE Filtration

Internal axial wire (wire-base)

  • Smooth internal screen surface
  • Facilitates cleaning with an internal axial-movement scraper
  • The flow moves across the wire edges for effective dewatering
  • Application : Trommel screens with internal feed / Systems with an internal rotor or screw / Dewatering systems / Baskets / Automatic filters

Cylindrical Screen for INSIDE OUTSIDE Filtration

Internal circumferential wire (re-rolled)

  • Smooth internal screen surface
  • External axial support rods
  • Application : Screw press

Nozzles

Standard diameter : 50 mm

  • Economical and non-plugging design, High open area
  • Application : Collectors and distributors installed uniformly across a plate or a header lateral arrangement / Demineralizers, water softeners and in pressure and gravity sand filters

Screen Lateral Systems

Effective media retention in a wide range of application

  • Uniform collection or distribution flow of a gas or liquid through treatment media without dead zones
  • The assemblies can be designed to accommodate flow in any direction
  • Slot size 0.05 mm and up in 0.01 mm increment, diameter from 20 mm up
  • Assemblies are typically made with type 304SS, 316LSS or other exotic alloys

WATERWELL

Continuous-slot Vee-Wire® screens

Screen design is, without question, a critical factor in designing an efficient well. The well should be designed to serve two basic purposes: allow access to the formation for development purposes and permit unobstructed entry of water into the well.

Continuous slot, Vee-Wire® stainless steel screens permit water to enter along the entire screen and allow maximum access to the water bearing strata, for proper development to take place. This in turn leads to:

  • Lower pumping costs: Less drawdown inside the well
  • Less pump wear and longer well life

High Capacity Intake Screens

The Hendrick screens intake design offers many benefits

  • LOW COST : The Water Intake has a simple design that is connected directly to a pipe system and has no moving parts simplifying installation, operation and maintenance
  • LIMITED MAINTENANCE : Fully welded construction with no moving parts featuring a non-plugging slot design. Manufactured using corrosion and encrustation-resistant materials
  • ENVIRONMENTALLY FRIENDLY : The slot- through velocity of the Hendrick Intake is very low (> 0.15 m/s) prevents damage to aquatic life
  • EASY CLEANING : The air backwash system (Airburst™) is remotely located and automatically operated and does not require diver intervention
  • NO DISPOSAL OF DEBRIS : During backwash, debris is carried away by the current, with no further on-land debris disposal required
  • ADAPTABILITY : Each water intake is designed specifically for site conditions

COANDA Sieve Screen

Efficient water intake screening in remote and rugged streams or rivers where elevation drop across the weir is available.

The unique concept and design minimizes debris impingement by maintaining enough water flow over the screen surface to sweep any solids off the end of the screen. If the pool of water upstream exceeds the screen design, excess water will pass over the screen and on downstream. If the head over the ogee crest falls below design flow debris will begin to accumulate on the screen surface. This accumulation will not adversely affect through-screen capacity but will hinder debris by-pass. The screen structure is of quite durable construction and will pass small tree limbs and stones without being damaged.

Due to the wide range of options available and criteria for correct model selection, pricing of screening systems is available on application only. Please contact DEECO.
