Beckton Desalination Plant

gzamacois — Thu, 06 May 2010 11:13:39 GMT

Project: Beckton Desalination Plant
Entity: Thames Water Utilities Limited
Location: London, Great Britain
Capacity: 150,000 m³/day

Objective:

Design and construction of the first desalination plant in Great Britain.

Description:

The catchment is carried out in the Estuary of the River Thames during the hours of low tide, in order to guarantee the appropriate quality of the raw water of the process.
Hypochlorite dosage, polyaluminium chloride and sulphuric acid.
Lamellar sedimentation.
The plan has 17 sand filters.
19 filter prelayer with earth diatom of 28 µm.
For safety filtration, the plant has 10 selectivity cartridge filters of 5 µm.
Dosage of bisulphate for the elimination of residual chlorine.
The reverse osmosis plant uses a unique design with 4 stages to minimise the specific energy consumption of the process, as well as the flow in the main elements at each stage.
Stages 1 and 2 are configured with 9 frames and each one of these with a supply pump and another booster pump, while stages 3 and 4 are configured with 3 frames.
The supply and booster pumps are equipped with a speed variator to adapt to the reduction in the conditions of supply pressure of the reverse osmosis.
The Pelton Turbines are coupled to the supply pumps of the 3rd stage for energy recovery.
84% conversion.
Remineralisation through dosage of lime, carbon dioxide and magnesium sulphate.

Adelaida SWRO

gzamacois — Thu, 06 May 2010 11:12:34 GMT

Project: Adelaide Desalination Plant
Client: SA Water
Location: Port Stanvac, Adelaide, South Australia, Australia
Capacity: 300,000 m3/day

Objective:

Reverse osmosis sea water desalination plant to supply drinking water to the city of Adelaide and its surrounding area.

Description:

The desalination plant in Adelaide is located 52m above sea level, and this geographical positioning along with the strength environmental protection measures make this plant unique in both design and construction. The Adelaide plant in Australia is revolutionary, incorporating an advanced ultrafiltration membrane pre-treatment and a two pass reverse osmosis membranes configuration which provides a lower energy usage and an increase in the recovery of the system.

Intake

The sea water intake is composed of a 1.5 km tunnel
Sodium hypochlorite and sulphuric acid can be closed in the intake minimise biofuiling and to maintain tunnel conditions
The sea water from the intake is pumped up to a height of 57m using 12 dry chamber pumps with a total capacity of 28,400 m3/h

Pre-treatment

Solids filtration systems using 24 racks of disc filters
Ability to add coagulant agents, active carbon and sulphuric acid
Pretreatment using 28 ultrafiltration submerged membrane cells
Safety filtration using 20 filter cartridges prior to the RO
Ability to add antiscalant agent to avoid salt precipitation in the system
Ability to add sodium metabisulphite to neutralise the oxidising agent added in the intake
12 high pressure pumps

Reverse Osmosis

Energy recovery system using ERI pressure exchangers
Energy recovery from the saline concentrate output, prior to discharge, using turbines which produce energy using the hydraulic jump between the level of the plant and the sea water
20 first pass trains and 20+10 second pass trains which have been technically developed by ACCIONA Agua
First train production capacity of 15,000m3/day, each made up of 180 pressure vessels, and in each one, 8 reverse osmosis membranes
Total recovery rate of 48%
Low energy consumption

Post Treatment

Remineralisation using lime and CO2
Disinfection using chlorine and treatment using hydrofluorsilicic acid
2 treated water tanks each with a capacity of 25,000m3

Effluent treatment

Advanced treatment of the pre-treatment wash water
Neutralization of the membrane cleaning solutions
