Jeyranbatan Ultrafiltration Water Treatment Plants Complex

Jeyranbatan Ultrafiltration Water Treatment Plants Complex (UF) which was designed to supply of Baku and Absheron Peninsula with drinking water, was put into operation on October 28, 2015. The capacity of the UF treatment plant is 6.6 cubic meters per second (570 000 cubic meters per day). The plants complex were chosen one of the most important water projects in the world in Global Water Summit in Abu Dhabi in 2016. Companies from the US, Germany, Switzerland, Spain, Italy, Turkey and the Republic of Korea, as well as up to 30 local contractor organizations were involved in the construction of the complex.[1][2][3]

UF treatment plant processes water which is naturally purified in the Jeyranbatan reservoir with capacity of 186 million cubic meters. The raw water is primarily treated in the coarse screen building by using 7Nos 3000-micron automatic self-cleaning filters. Water transmitted from the raw water tank is treated at the highest level within 20 seconds passing through 200 micron filters firstly and then 0.02 micron filter modules. The treatment of the water is carried out in 5280 membrane filters. This process is performed mechanically closed environment by application of automation controls without implementing any chemical treatment and natural mineral content of the water is fully preserved. Water produced in the plant meets the standards accepted by the World Health Organization as well as other international organizations.

Some quality indicators of water processed in the filters (chlorine residue, cloudiness, pH, TOC) are controlled online. More parameters of raw and treated water are studied and quality indicators are fully controlled in the laboratory of the complex. The volume, pressure of the water transmitted to the plant, each stage of process of water, storing, and transportation processes are fully automated. All technological processes are managed in the SCADA control center.[4]

Processed water is collected in the treated water tank with capacity of 10.000 cubic meters and is pumped to the Absheron reservoir which locates at 118 meters above sea level and water is distributed to the networks by gravity.

Jeyranbatan-Zira transmission main with total length of 83,5km (DN1600-1000mm), and Saray, Balakhani, Ramana, Gala, Zira reservoirs with a total capacity of 90,000 cubic meters which are located along the route of Jeyranbatan-Zira transmission main were constructed in order to provide water to Baku and other residential areas. More than 1 million inhabitants of peninsula have been provided with high quality and sustainable drinking water by this infrastructure.[5]

The UF treatment plant include 5280 filter modules with capacity of 1,25 l/sec each, 13 thousand valves and equipment, 116 pumps, 6 transformers, flow meters, backwash and chemical dosing pumps, ventilation, heating and cooling systems, energy block, generator, transformer, as well as working rooms, conference hall, SCADA control room.

3Nos intake pipelines (DN1600mm) were constructed for taking water from the reservoir by applying tunnel boring machine method. A water distribution chamber was built on the shore of the reservoir in order to control volume of the supplied water and adjust raw water capacity to meet the needs of the plants. 4 pipelines with diameter of 1400 mm were laid from the water distribution chamber to the UF treatment plant.[6]

30km of pipelines of in varied diameter range, 242 km of electrical and 13 km of fiber optic cables, 7120 tons rebar, 3000 ton steel structure, 65 thousand cubic meters concrete were used during construction of the complex. Approximately 700,000 cubic meters of earthworks was performed, 19500 square meters of area was covered with asphalt and greenery work has been carried out in the area of 28000 square meters.[7]
