Activity concentration of the radionuclides presented in liquid effluents has been evaluated in IFIN-HH laboratories. Gamma-ray spectrometry analyses have been performed for liquid and residue samples, and gross beta activity has been evaluated only for residue samples. Co, Cs, Eu, Eu and Ag radionuclides have been found with a higher concentration in residue samples. Taking into account previo...

Estimates of NH4+-and NO2-oxidizers in samples from four activated sludge plants treating mainly domestic sewage were obtained using a most-probable-number (MPN) technique. Ranges of concentrations per milliliter of each, respectively, were 1,010 to 3,880 and 79 to 145 in settled sewages, 32 to 7,420 and 2 to 1,010 in secondary effluents, and less than 0.1 to 622 and 0.1 to 70 in chlorinated se...

Bacterial consortia BMP1 (containing six isolates), BMP2 (three isolates) and BBP (three isolates) were isolated from textile affected soil, sludge and effluent of Hudiara drain in vicinity of Nishat Mills Limited 5Km Off 22Km Ferozepur Road Lahore, Pakistan. These consortia were capable of degrading red, green, black and yellow dyes and were resistant to heavy metals (Cu, Cd, Cr, Ni, Mn & Pb)....

Most of the phenol compounds are toxic and have been considered as hazardous pollutants. Several physicochemical and biological methods are available to detect and monitor the phenol pollutants in water and soil. In the present study, phenol constituents of winery, paper and plastic industrial effluents were successfully detected employing tyrosinase-gold nanoparticles bioconjugate. The synthes...

The discharge of effluents from material ventures has been a noteworthy worry of the cutting edge world because of the colossal contamination that these effluents advance on the water assets. Among the engineered colors discharged in effluents from material ventures, azo dyes are a standout amongst the most unfavorable classes since it is exceedingly determined in the oceanic environment, becau...

predict the quality of bowel preparation before colonoscopic examination, this would be a very useful time-saving and cost-saving method. In the case of a prediction of inadequate preparation, these patients may benefit from additional preparation, which may be particularly useful if it can be administered in the endoscopy unit followed by colonoscopy on the same day. Fatima et al. reported onl...

Tightening quality standards for European waters has seen a move towards enhanced wastewater treatment technologies such as granulated organic carbon treatment and ozonation. Although these technologies are likely to be successful in degrading certain micro-organic contaminants, these may also destroy compounds which would otherwise complex and render metals significantly less toxic. This study...

The metalworking industry is responsible for one of the most complex and difficult to handle oily effluents. These effluents consist of cutting fluids, which provide refrigeration and purification of metallic pieces in the machining system. When these effluents are biologically treated, is important to do this with autochthonous microorganisms; the use of these microorganisms (bioaugmentation) ...

This study assessed the removal efficiency of organic matter and how it relates to the decrease of toxic and mutagenic effects when an anaerobic reactor is used to treat the bleaching effluent from two kraft pulp mills. Parameters such as COD (chemical oxygen demand), DOC (dissolved organic carbon), AOX (adsorbable organic halogen), ASL (acid soluble lignin), color, chlorides, total phenols and...

This study evaluates the occurrence of Cryptosporidium oocysts and Giardia cysts in reclaimed effluents if method 1623 with the Envirochek capsule filters (standard and high-volume [HV] filters) and a modified version of the Information Collection Rule method (ICR) with the polypropylene yarn-wound cartridge filter are used. The recovery efficiency of the analytical methods was evaluated with s...
