The performance and degradation mechanism of sulfamethazine from wastewater using IFAS-MBR

, 2020
Sulfamethazine (SMZ) is an important sulfonamide antibiotic. Although the concentration in the environment is small, it is harmful. The drug residues can be transferred, transformed or accumulated, affecting the growth of animals and plants.

Experimental investigation of petrochemical industrial wastewater treatment by a combination of integrated fixed-film activated sludge (IFAS) and electro-Fenton methods

, 2020
The toxic and dangerous wastewater from the petrochemical industry should be effectively treated before it is discharged into the environment. In this study, the electro-Fenton (EF) process was performed as a pre-treatment for petrochemical wastewater ...

Contrasting distribution of antibiotic resistance genes and microbial communities in suspended activated sludge versus attached biofilms in an integrated fixed film activated sludge (IFAS) system.

Science of the Total Environment, 2020
Suspended activated sludge (AS) and carrier-attached biofilms simultaneously exist in an integrated fixed film activated sludge (IFAS) system. However, the differentiation of antibiotic resistance genes (ARGs) and microbial communities in different types

İnşaat Sözleşmelerinde Eksik İfa Ayıplı İfa Ayrımı

2022
İnşaat sözleşmelerinde eksik ifa ve ayıplı ifa ayrımı somut uyuş-mazlığa uygulanacak hükümlerin belirlenmesi açısından son derece önemlidir. Teslim edilen inşaat ayıplı ise yüklenici TBK mad. 474 vd. hükümlerine göre sorumlu olur. Eksik ifa halinde ise iş sahibi genel za-manaşımı süresi içerisinde ifa etmemeye ilişkin genel hükümlere başvu-rabilir ...
