@Ataköy Advanced Biological Wastewater Treatment Plant Since the Marmara Sea is at critical levels of pollution, the wastewater from the settlements in the basin should be carefully collected and treated. Ataköy Advanced Biological Treatment Planı was established in 2010 with 390.000 cu.m/day biological treatment and 600.000 cu.m/day pre treatment capacities, on average. Ataköy Piant treats the water arriving from Bakırköy, Bahçelievler, and Bağcılar counties, as well as parts of Küçükçekmece and Gaziosmanpaşa (GOP) counties. @ıncorporation of CPVC Pipes in Fire Sprinkler Systems Fire Sprinkler Systems are known as the most effective and validated systems forfire fighting in early stages, before the flames injure the people or damage the properties. in the buildings where fire sprinkler systems have been used and incorporated in their designs for over 100 years, no human beings have been injured in the fires. Almost ali new shopping malls, hospitals, schools, high rise buildings and hotels are equipped with fire sprinkler systems. CPVC is a thermo plastic usedfor making pipesthat have been successfully installed in fire sprinkler system applications for many years. This material, as well as its several other advantages, is preferred for its easy installation facilities. � How the su eti on fittings in a centrifugal pump should be �designed? Design of a section fitting and the size of its suction pipe, as well as selecting correct equipment and installing them correctly, play an important role in the lifetime and the performance of a centrifugal pump. lf the piping at the suction end of the pump is not installed correctly adhering to some stringent rules, we can say that its ideal lifetime is reduced to some extent and drops will be experienced in the pump's hydraulic efficiency. The suction line must be as short as possible and the number of elbows should be kept at a minimum. As the losses are minimized at the suction end, the possibilities of problems arising due to suction are reduced. Also, problems are notfaced in achieving NPSHm> NPSHi condition and consequently probability of cavitations in the pump is eliminated. 214 Tesisat Dergisi Sayı 185- Mayıs 2011 - - -·- ====:=-...=:.-:.. ::-.::-.: -- ------.... �----- _._ __ -... ---•'"""'-....- ___ ,. __ ------ ..........____ ----�- ---·-"' __...,._..,_.. ... .., __ .. __ ... -- ----- ........ .. --·---_.,______ ...._.. __ _ ------ ., ...______ .... _,_ __ ,.._ ·----..... _ .. __ .,. _,____,..__ ____ ,.. ----__ .... __ _ .. ---·------...- ___.,............ _,._____ ----- --·-,ı..... _,.,..,_..,._ ----- _.,.,_,..._,w ----- ------- __ ., __ ..,_ '11 ==--- m:=....'--- ==-..:- == ► ....--.....- ,;;;;;;;-- ... ... ----- 8 ::.::--;...-: �-=�:: :.=..::: � ��?E :. ... ?�� =:-�··=· � ��-�: §�� � __ ........... -..... ·- ---·--- __.,,._.,.__ -·- 11&,............,. ..,,,., CPVC Sorulama Sisteminin Yanı:ın Sprinkler Sistemlerinde Kullanımı ----- ____ ı:::ı::>!' ___ ........ �------·-- ___ ,. ____ ..,.___ ___ ,.. _____..___ m.ıık•tı Santrifüj Pompanın Emme Tesisatı Nasıl Olmalı? ..,.,,.. ,.. ___ _ _____ .,..,. -... --·---· .., ___ .,. __ ---- --·--- --ıo---... .... -----_,,.,.,____ ----- ---- _...ll>M••-- •-•--•- ..,_____ ____._.... ----il""� ------ ·----- - --- ,._ .. .., __ . __ ..,. __ _ ------·---"'-... ...... __ ,.._ --� ..... --__ .,. .. ______ .., .... -----.... __ ,.,___ -----·- -- ........ .,_,...�_ -- _____..,_ .,. ___ ... _ ·-----_,. ____ ,, _..,____ ------- _,..____ ., ----·- ·----- ----- ----·- - ----- ---·-... - ---- ·-·---- ----- .... ---- -----.... , -------- -- --.. -·-- ---- ·--- - ---- ______... --·--- --...--- _,__....._ ---...ı.._ -·---- ----·- -----·- .,...._____ _.. __ .,_ ----- ---... -·- -�--... , .... ���� ,......._ ı,.ı,..._ ��� ._ o,.,,,. _ _ _ _ --� .............- _,__......,.,_,___ ıııııo1t•�--ı..........o,,..,... �-....,.,..l'ıl1,...._l11111t ,.,ılo""............�.. ---- ==-& ..
