Actinomycetes isolated from different soil samples were tested for their abilities to utilize spent sulfite bleach effluents from a paper mill. Degradation and dechlorination of the chlorinated compounds in the effluents of the first two bleaching stages, i.e., chlorination stage [(C + D)red.] and alkaline extraction stage (E1O), were monitored by determining total organic carbon (TOC) and acti...

In order to assessing whether algae can reduce the pollution concentration of the effluents by absorbing the nutrients, it is found that effluents can effectively be treated by employing algal organisisms such as Oscillatoria and Stigeoclonium species and these organisms are frequently found in the polluted waters and they were recorded as pollution tolerant forms. In the laboratory procedures ...

Effluents from pulp and paper mills are highly toxic and are a major source of water pollution. Nearly 250 chemicals have been identified in effluents which are produced at different stages of papermaking. Their toxic nature is derived from the presence of several naturally occurring and xenobiotic compounds which are formed and released during various stages of papermaking. If applied under ap...

Abstract Industrial effluents containing appreciable amounts of phenol and formalin may represent a problem when these effluents undergoing biological treatment. Experience in field of biological treatment for wastewater contains high concentrations of formalin showed high inhibition effect of formalin to biodegradation, specifically at higher concentrations more than 225 mg/L [3]. Also, as phe...

This correspondence describes the successful development of methods for the recovery, isolation and detection of Cryptosporidium oocysts in wastewater and biosolids. Wastewater from one plant was used to optimize methods in raw influent as well as primary, secondary and tertiary effluents. Raw influents and primary effluents were concentrated using centrifugation followed by isolation of Crypto...

Ekológia (Bratislava), vol. 33, no. 1, p. 60–66, 2014. The first part of this investigation studied complex nature of chemical oxygen demand (cod) parameter on local and overall effluents, which were obtained from two pulp and paper mills, located i...

the industrial effluents of three textile plants in the south of tehran were studied. in each plant all related factors such as raw material consumption, production processes and water use at different points were examined. these plants discharge their effluents into the environment without any treatment. the common characteristics of these wastes are quantity and quality variability, organic p...

Concern has been raised in recent years that exposure to wastewater treatment effluents containing estrogenic chemicals can disrupt the endocrine functioning of riverine fish and cause permanent alterations in the structure and function of the reproductive system. Reproductive disorders may not necessarily arise as a result of estrogenic effects alone, and there is a need for a better understan...

To reduce the release of pharmaceuticals and endocrine disruptors into the aquatic environment or to remove them from wastewater intended for direct or indirect reuse, the application of advanced wastewater treatment may be required. In the present study, municipal wastewater effluents were treated with ozone (O3) in a pilot-scale plant consisting of two bubble columns. The investigated effluen...

In the early 2000s, most of the effluents from the Paris agglomeration (12 million inhabitants) were still discharged after only a standard activated sludge treatment of carbon, thus releasing a high ammonium load. This triggered the growth of nitrifying bacteria in the river and caused a deficit of dissolved oxygen concentration 200 km downstream, at the entrance of the estuarine area. From 20...
