Brackett Green Single Entry Cup Screens, water intake screens, are recommended for installation on raw water intakes where low maintenance is a prime consideration. They ensure the effective removal of floating and suspended solids, thus protecting critical equipment such as pumps and heat exchangers. These water intake screens, fitted with mesh ranging from 0.5mm to 10mm, can be installed as a single unit or as part of a two or three stage system.

Low Maintenance Costs
With each water intake screen installed in a concrete chamber the initial capital cost of civil works may be higher than for a traveling band screen. However, this extra cost can normally be recouped within the first 3 to 4 years of operation, depending on site conditions, thanks to the cup screen’s extremely low maintenance requirements.

The main cooling water intakes of power stations, refineries and petrochemical plants using fresh or sea water are among the applications for the Brackett Single Entry Cup Screen. It is also used at the intakes to water treatment and desalination plants which utilize conventional or membrane technology.

Solid Shaft
The Brackett Single Entry Cup Screen is strongly built with a fabricated drum and a solid horizontal center shaft revolving slowly in heavy duty self-aligning roller bearings. These are lubricated from deck-level reservoirs.

Water flows from the inside to the outside of the cup through mesh panels arranged around its periphery. These mesh panels are cleaned by back washing at deck level.

The water intake screen is driven by a drive unit positioned at deck level, with the final drive being by a nylon pinion which engages with a gear ring on the back plate of the screen. The drive gear and the main shaft assembly are the only moving parts.

Individually designed
Brackett Single Entry Cup Screens are designed to suit each individual application, with specific features as required to meet operating and site conditions. Water intake screens of this type may be up to 10 meters in diameter and up to 3 meters wide.

Ancillary Equipment
Eimco Water Technologies can supply all the plant necessary for a complete screening station.
