HLPH Facility – Refinery / Seawater Intake Filtration System


Project introduction

For the Elsham water treatment plant owned by Anglian Water, Hubert was awarder the contract for delivery and installation of 3 micro strainers. The facility in Elsham processes 75 million litres (16.5 million gallons) of water every day. The plant supplies much of the drining water for northeren Lincolnshire. Anglian Water had a lot of problems with zebra mussels that clog the water inlet pipe from the river Ancholme. The zebra mussel, Dreissena Polymorpha, is a specied of small freshwater Shellfish.

The seawater intake filtration system is designed to remove completely sea grass / weed, debris, plastic bags, wood chip, mollusk, jelly fish etc. The system consist of sluice gates positioned upstream and downstream of a Hubert Bar Screen and Travelling Band Screen. Motorized Hubert Sluice Gates are used for drying the channel of each intake ‘train’ to give access for maintenance of both bar screens & travelling band screen.

Hubert Bar Screens were used to keep out large parts. Our screens are designed to prevent vibrations during all operating conditions. They are therefore rigidly mounted on supporting profiles. Bar screens will be periodic cleaned by an automatic raking system, placed on a monorail construction just downstream of the inlet sluice gates. Two (1 working / 1 stand-by) trash raking systems are included for a full screening function.

The installation is provided with Hubert Travelling Band Screens based on a dual flow design. This will mean that water will flow from the outside of the screen through the mesh panels to the inside of the screen and then out through an opening in the back civil work wall of the screen chamber. The debris, which is collected on the outside of the mesh will be lifted above deck level, where it will be removed by high pressure water spray and then disposed.
