BILKENT HOLDING BILKENT ENERGY PRODUCTION INDUSTRY AND TRADE INC. / ANKARA
Sector: Energy Industry
Location: Ankara/Turkey
Raw water source:Municipal water
Capacity: 360 m3/day
The system is designed and installed in Bilking University campus to provide steam generators of power production station with water for steam generation which is used to produce the university’s electric energy, energy for production facilities of the shareholders of the company, Meteksan Paper tfactory’s operational steam demand and steam for heating all the buildings inside the campus. The deionized water used in steam generation is obtained by 2 step reverse osmosis system and mixed bed deionization system.
As a first step, municipal water is fed to the automatic multi layer sand filter with fiberglass housing and surface piping with 25m3/hour filtration capacity and to the carbon filter for pre-filtration using two pumps with 25m3/hour capacity and working at 5-7 bars.
Before 1st step reverse osmosis system, filtered water is adjusted for pH value and filtered by cartridge filters providing sensitive filtration. tfurther, water is passed through reverse osmosis system which has 18 membranes using high pressure pumps.
Product water of 1st step reverse osmosis system is pH adjusted and stored to be directed to the 2nd reverse osmosis system using transfer pumps with 18.75 m3 capacityeachat 3 bars. To protect anydecreaseinmembraneperformancebothsystems have membrane cleaning unit. Water after the second step reverse osmosis system is degasified for carbon dioxide removal and stored for feeding demineralization unit. Mixed bed deionization system is designed in tandem and provides 15 m3 deionized water continuously. Chemical regenerations are realized automatically, the system is controlled in online regime. The system is designed to provide deionized water with conductivity less than 0.2 micro Siemens at constant output for 2 years.
Two step reverse osmosis system and mixed-bed deionization system are designed to work together to provide steam generation unit with deionized water.
