Wastewater treatment

The main objective of this research was to evaluate the potential use of a bench-scale anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal as inert support for removal of sulfide and organic matter effluents from an ASBBR (1.2 m3) utilized for treatment of sulfate-rich wastewa

Cattails and reeds are the most common plants in constructed and semi-natural wetlands for wastewater treatment, and can play an important role in both nutrient and heavy metal retention. On the other hand, both plants are highly valued in ecologically oriented construction. The aim of this chapter

Urban wastewater from secondary treatment is rich in compounds of nitrogen, phosphorus, and other nutrients. The elimination of such compounds, in the few cases in which it is carried out, is achieved through tertiary treatment. The development of an alternative study is proposed on a tertiary treat

A recirculating vertical flow constructed wetland (RVFCW) has been developed for the treatment of grey water. The overall aim of this research was to apply the RVFCW, a decentralized, small-scale system, to the treatment of domestic wastewater (DWW), modifying it, where necessary, to produce effluen

This study focused on the removal of toluene from the wastewaters of the chemical industry. The tests were carried out on a polydimethylosiloxane (PDMS) membrane filled with carbon black (PDMS'/cb) and another without the filling (PDMS). It was confirmed, that the addition of the hydrophobic filling

This paper discusses the use of membranes for gas transfer in water and wastewater treatment. Typically, membrane bioreactors use microporous membranes to enhance treatment through improved solids separation. In a number of recent research studies, however, gas-permeable membranes have also been use

This paper presents MBR performances observed under steady and unsteady state conditions where influent and permeate flow rates were punctually and simultaneously increased. Experiments were performed in a submerged membrane bioreactor presenting a 50 L working volume. Two capillary membrane modules

Water shortage has become a global issue and not only a problem relevant to arid zones. In the past decade desalination of sea and brackish water has been found to be a technically and economically acceptable solution for water shortage. More recently, desalination of wastewater effluents has also b

A new method of hydrolytic acidification-sequencing batch reactor (SBR) process in aquatic products processing wastewater treatment is given. In the stage of the pretreatment, the hydrolysis-acidification technology was adopted, it is effective to improve the biodegradability of the wastewater. The

A new method of separation of carcinogenic aromatic amines in wastewater is given. With SDS (C12H25O4SNa) and β-CD (β-cyclodextrin) addition, it is effective to improve separation. At the same time, it forms mixed micelle. As a result, a micellar electrokinetic capillary chromatography (MECC) system
