Abstract

Calcium and Magnesium elements (+2) valued ion states form hardness in waters. Although it does not pose serious risks for human health, hard water causes negative effects such as decreasing production quality in the industry, shorten the life of the pipes and the life of the devices that produce or consume hot water. Water is classified as CaCO3 equivalent (0 - 75 mg / L) soft, (75 - 150 mg / L) medium hard, (150 - 300 mg / L) hard, ( >300 mg / L) as hard water. Membrane Capacitive deionization (MCDI) is an effective process for removing hardness types. In this study, taking the usage area of treated water in hardness removal, into account, water with different proportions of Ca2+ and Mg2+, which are classified as hard water, have been treated with MCDI to produce process water and drinking water. As a result of the studies, water containing 300 mg CaCO3 / L hardness in the process water production in the range of 90% - 97%; in drinking water treatment, it was treated with% 71 -% 82. When cost analysis is performed, costs for process water vary between 0.01 - 0.02 $ / m3 , while this cost for drinking water varies between 0.009 - 0.016 $ / m3 .

Özet

Kalsiyum ve Magnezyum elementlerinin (+2) değerlikli iyon halleri sularda sertlik oluşturmaktadır. İnsan sağlığı açısından ciddi riskler oluşturmasa da sert sular sanayide üretim kalitesinin düşmesi, boruların ömrünün azalması, sıcak su üreten ya da tüketen cihazların ömrünün azalması gibi olumsuzluklara sebep olur. Sular CaCO3 eşdeğeri olarak (0 – 75 mg/L) yumuşak, (75 – 150 mg/L) orta sert, (150 – 300 mg/L) sert, ( >300 mg/L) çok sert su şeklinde sınıflandırılmaktadır. Membran Kapasitif deiyonizasyon (MCDI), sertlik türlerinin giderilmesinde etkili bir prosestir. Bu çalışmada sertlik gideriminde arıtılmış suyun kullanım alanı da göz önünde bulundurularak çok sert su sınıfına giren farklı oranlarda Ca2+ ve Mg2+ içeren sular MCDI ile arıtılarak proses suyu ve içme suyu elde edilmeye çalışılmıştır. Çalışmalar neticesinde 300 mg CaCO3/L sertlik içeren sular proses suyu üretiminde %90 - %97 aralığında; içme suyu eldesinde ise %71 - %82 oranlarında arıtılmıştır. Enerji için Maliyet analizi yapıldığında proses suyu için maliyetler 0,01 – 0,02 $/m3 aralığında değişirken içme suyu eldesi için bu maliyet 0,009 – 0,016 $/m3 aralığında değişmektedir.
