Bisphenol A (BPA) is an endocrine-disrupting compound, which encountered in many areas of our daily life (feeding bottles, automotive parts, etc.).BPA causes a severe health problem and transmitted to the environment through surface water, groundwater, industrial wastewater, leakage BPA depots, etc.In this study, degradation synthetically prepared wastewater was investigated by using peroxy electrocoagulation method with iron electrodes.The effects pH, amount hydrogen peroxide, current...

The increasing environmental pollution due to urbanization after the industrialization revolution affects global eco-system, including human existence. Waste recycling projects should be implemented by considering economic benefits besides reduction of harmful effects on environment and health. glass process constitutes significant part prepared with this purpose. In study, waste discarded all students staff at Esentepe campus Sakarya University has been used calculate costs collecting,...

Su sertligine iki degerlikli metal katyonlari sebep olur. Dogal su1arda en sik rastlanan kalsiyum (Ca+2) ve magnezyum (Mg +2) iyonlarinin yarattigi sertlik cok az hata ile toplam olarak kabul edilebilir. Genel halk arasinda sert su makbul sayilmaz. Sert sular sagliga zararli olmarnakla birlikte, yemek pisirmeye, icmeye, camasir yikamaya elverisli degildirler. Sertlik, sabunun kopurmesini azaltarak, kazan taslari olusturarak, bazi endustriyel proseslere zarar vererek suyun tadini bozarak...

Textile industry wastewater includes organic dyes and decomposition products which could have toxic mutagenic effects on life.The majority of industries in this sector use nonbiodegradable, heat-resistant, light, oxidizing agents therefore synthetic that are difficult to remove color.In study, Dianix Yellow Brown CC (0.22%), Rubine (0.79%) Setapers Blue CE3R (0.015%) containing disperse dye been used the production from dyehouse.In textile has treated applied adsorption photocatalytic...
