Atotonilco WWTP

gzamacois — Thu, 03 Feb 2011 17:48:09 GMT

Proyect: Atotonilco WWTP
Entity: CONAGUA
Localition: México D.F., México
Capacity:

Flow: 35 m3/s and a maximum treatment capacity of 50 m3/s.
Population: 10,500,00inhabitants.

Object:

The contract is for the construction and subsequent operation and maintenance of what will be the world’s largest wastewater treatment plant (WWTP) to date, located in Atotonilco (Hidalgo state).

Description:

The consortium was awarded the government tender, on December 18, thanks to a proposal that was deemed not only financially solid but also fully compliant with the technical, economic and legal requirements laid out in the conditions of the tender.

The plant will have a nominal average treatment capacity of 35m3/second and a maximum treatment capacity of 50m3/second, including the evacuation of the solid waste and sludge generated. In addition, the facility will be equipped with a cogeneration system which will use the biogas produced during the digestion process, making for maximum energy efficiency.

The future Atotonilco WWTP will be the largest of its kind on the planet and one of the largest-ever works among those envisaged by Mexico’s government-sponsored Cuenca del Valle Water Sustainability Program, in the same state as the country’s capital, Mexico City. It will provide wastewater treatment for 10.5 million inhabitants.

In addition, the treated wastewater will be used for irrigating 80,000 hectares of land.

Peravia DWTP

gzamacois — Tue, 01 Feb 2011 17:33:19 GMT

Proyecy Peravia DWTP.
Client: Instituto Nacional de Aguas Potables y Alcantarillados (INAPA).
Location: Peravia, Dominican Republic.
Capacity:
- Flow: 86.400 m3/day.
- Population: 138,000 inhabitants.

Object:

The construction of this supply plant stems from the Dominican Government’s commitment to provide the local population with a greatly required infrastructure -Peravia province has been blighted by a shortage of drinking water for more than 40 years.

Descripción:

Construction and commissioning of the Drinking Water Plant of Peravia which includes the works of a 17,5 km adduction line, a drinking water plant with 86.400 m3/day capacity and the water supply network for the surrounding villages.

The plant will have cascade aeration, dosage of coagulant and flocculant reagents, lamellar settler, sand filtering, disinfection with chloride gas, sludge treatment by static thickening and drying periods.

La Chira WWTP

gzamacois — Tue, 01 Feb 2011 11:22:25 GMT

Proyect: La Chira WWTP
Entity: Agencia de Promoción de la Inversión Privada
Localition: Lima, Perú.
Capacity:

Flow: 544.320 m3/day.
Population: 2.500.000 inhabitants.

Object:

The WWTP will help contribute to solving Lima's sanitary and environmental problems caused by the effluent of the Surco and Circunvalación collectors which discharge directly into the sea without prior treatment.

Description:

The contract is for the design, construction, financing and operation and maintenance of La Chira Waste Water Treatment Plant (WWTP) and underwater discharge pipeline, located in the south of Lima.

The concessionaire will build the necessary infrastructure and will provide the national drinking water and sewer system Servicio de Agua Potable y Alcantarillado (Sedapal) with treatment services of roughly 25% of the wastewater of the Peruvian capital, covering 2.5 million people. The plant will have an average capacity of 6.3 cubic metres a second and a maximum level of 11.3 metres a second.

The new plant will also aid the recovery of the environment of the beach areas which are currently polluted, increasing their use as recreational areas and for tourism, and helping to promote tourism projects in the area of influence.

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

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

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
