in this research performed during 1993-1994, the effluent of behran oil refmery, in south of tehran, which produces different types of industrial oil and greases, was studied and 3 methods of gravity separation, coagulation and flocculation and dissolved air flotation were investigated. in the first phase of the survey, the quality and quantity of the effluent were determined. this showed an av...

This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...

background: today, in many countries, wastewater treatment plants effluent is an important part of the renewable water resources. in this case, the effluent quality standards are developed and used is important. the aim of this study was to investigate the potential use of wastewater plants effluent restricted irrigation. methods: in this descriptive - analytical study, samples was collected fr...

Though the need for appropriate wastewater management technologies is undoubtedly a realized issue, so far there has been very little action taken towards wastewater treatment in Nepal. The centralized approaches of wastewater management have been unsuccessful as the existing traditional lagoons or activated sludge type wastewater treatment plants are not functioning or partially operating at f...

introduction: due to the risks of hormones on human health and aquatic life, the aims of this study were to determine the efficiency of estrogen removal in the different stages of shiraz wastewater treatment plant using activated sludge process and marvdasht wastewater treatment plant using aerated lagoons process and also comparing the performance of both systems in removing the hormone of est...

The industrial wastewater treatment is gaining more and more importance with the rapidly increasing need for expansion of existing plants and erection of new plants to cater the needs of chemical, pharmaceutical and petrochemical products and intermediates. The treatment of the wastewater is key to the sustainable and acceptable industrial growth. Petroleum industries and refineries are importa...

The wastewater from petroleum industries contains high organic matter content, oil and grease, dissolved solids and turbidity. The petroleum wastewater normally treated in a plant comprising of primary, secondary and tertiary treatments. The high organic loading needs to be treated in biological treatment step. Biological treatment can be suspended growth or attached growth type. Activated slud...

Harnessing hydrogen competently through wastewater treatment using a particular class of biocatalyst is indeed a challenging issue. Therefore, biohydrogen potential of real-field wastewater was evaluated by hybrid fermentative process in a single-stage process. The cumulative hydrogen production (CHP) was observed to be higher with distillery wastewater (271 mL) than with dairy wastewater (248 ...

Tannery wastewater is heavily polluted containing appreciable biodegradable matters as well as inorganic substances like chromium, sulphide, chloride etc. Thus the composite tannery wastewater appears to be incompatible for direct biological treatment .Wastewater emanated from various sub-processes of tannery operation showed variable characteristics and also differential treatability. The pres...
