Passive Intake Screen

Product Description

Intake screen is designed for water extraction from reservoirs and rivers for use as drinking water, desalination plants, and other industrial uses. The raw water goes through the two cylindrical screens which leave the solids elements against the perforation or wedge wire. An integrated air purging system takes place inside in order to expulse the clogged solids with bubbles.They retain larger particles and water life floating in the river and protect pumps and installations further up the production line. The controlled lower slot velocity along the screen surface also reduces the likeihood of impingement and entrainment of marine life.Wedge wire intake screen also has a ability to be cleaned using an air backwash system whereby a controlled burst of compressed air is deployed.Our intake screen have great design flexibility and are constructed in a wide variety of shapes and sizes and from a variety of corrosion-resistant alloys. Specific processes and vessel requirements can be accommodated.

Benefits of intake screen include:

1.Continuous-slot design provides an increased open area .

2.The continuous slot formed by V-shaped surface wires ensures a two-point contact between the particles and the slot to minimize clogging.

3.Wide range of profile wires are available to suit most applications.

4.High-precision slot sizes are available to meet your requirements.

5.V-shaped surface wires allow for easy cleaning.

6.Very low pressure drop.

7.Additional supports are utilized to accommodate extreme load conditions.

8.Low maintenance.

Specialty of intake screen:

Mainly used to clean water extracted from the sea, rivers or lakes to be used as cooling water for process water or industrial sites, power, raw water, desalination plants, drainage channels and irrigation offtakes.

Optimum protection for aquatic life

Our intake screens are designed to ensure a constant flow velocity to improve protection of wildlife while reducing costs. There are no moving parts that could break down or wear out, eliminating the need for replacement components and costly repairs.

Airburst System

Over time, as a result of biofouling, the outer screen surface may require periodic cleaning to keep the screen functioning properly. An airburst system can be included as part of the intake screen design, where clearing of accumulated debris from the screen surface is required.
