Seawater Desalination technologiesSeawater Desalination is one of the most important processes which helps to prevent many problems in the future. Presently, at time of global and gradual reduction of water reserves, the problem of seawater desalination and water purification becomes quietly significant.

Agbor Engineering is developing seawater desalination together with water and waste water treatment technologies.

The most important desalination methods are:

Desalination on the semipermeable membranes

(Reverse Osmosis)

Comparison of desalination methods: Thermal Desalination (MED, MSF)

– is a power-consuming process.

Membrane Desalination (RO) – is a power efficient process.

World Water ReservesA large saline water layer, that covers main part of the earth's surface, is the whole entity. It has approximately constant composition.

The World Ocean is enormous. Its volume is 1,35 billion km3. It covers approximately 72 % of the earth's surface. The World Ocean consists of almost all the water on the Earth (97 %). Approximately 2,1 % of water is concentrated in the polar ice and glaciers. 0,6 % consist of fresh water in lakes, rivers and ground water. The rest 0,1 % is saline water of drilled-wells and brackish waters.


AGBOR Engineering develops engineering and performs supply of complex desalination installation of Mediterranean Sea water for MMK-Atakas, metallurgical plant in Turkey. Available equipment and technology are suitable for water treatment, supply and disposal.

Metallurgical plant MMK Atakash has two production areas in Turkey; one of them is situated in Iskenderun, and the other one – in Istanbul.

About project

Water-supply source sea water Salt content of the source water 40000 ppm Source water hardness 139 mg-eq/l Capacity requirement:

UF 57 600 m3/dRO 1-st stage 24 000 m3/dRO 2-st stage 16 080 m3/d

Complex Water Treatment Installation for MMK-Atakas

Technology is chosen by the following scheme:Seawater Ultrafiltation (2000 m3/h) Reverse Osmosis (1000 m3/h and 660 m3/h) Drainless Purification of chrome-, oil- and SSAS containing drains and equipment for dehydration.

Process automation and construction solutions perform technological processes according to Seller’s requirements. Customer’s water supply is designed with such schemes of the reverse water supply, as: contact (“dirty”) and contactless (“clean”) cooling circuits. It prevents industrial waste disposal outside the complex.

The project proposes 6 systems of contactless cooling. The systems are based on the principle of cooling water quality, input pressure, temperature and location.

Screen FiltersAutomatic self-cleaning filters, with nominal filtration value of 200 micron, are applied to prevent clogging and mechanical damages of the ultrafiltration membrane capillaries.

Advantages:

Cleaning without main flow interruption ; These filters are energy-independent; They don’t require technical service; They have easy installation and operation.

UltrafiltrationUltrafiltration is the most efficient method of the surface and sea water clarification which is used before Reverse Osmosis installation. Utrafiltration is based on the principle of water filtration through the polymeric porous material. It delays suspended and colloid particles and transmits dissolved salts.

Ultrafiltration has eight racks; each of them consists of 96 parallel membranes dizzer 5000 of Inge production.

Reverse OsmosisWater desalination, performed by Reverse Osmosis, is based on the principle of water filtration through the polymeric material (membranes) at high pressure. Pore diameter of polymeric material delays dissolved salts:

1st stage of Reverse Osmosis has five units; each of them consists of 50 parallel high pressure housings. Each housing has six loaded membranes Hydranautics of 8040 standard.

2nd stage of Reverse Osmosis has three subunits; each of them consists of 28 parallel high pressure housings. Each housing has six loaded membranes Hydranautics of 8040 standard.

Hydranautics (USA) is a worldwide leader of membrane manufacturing.



Pressure Exchanger ® (PX)Energy Recovery Inc. (ERI) is American company, a worldwide leader of energy-efficient devices manufacturing which are used for seawater desalination systems based on Reverse Osmosis technology.

Energy saving is about 40 %.
