Membranes Industrial wastewater

n developing countries, industrialization is the main cause of water pollution because of the various industries which generate wastewater that is needed to be discharged. The availability of fresh clean water is becoming increasingly limited in many areas of the world resulting in scarcity of potable water in many regions around the globe. The membranes have emerged as an efficient compact technology for municipal and industrial wastewater treatment.

Quantification of mass flows in production lines and waste treatment lines, as well as quantification of energy consumption at a factory is always challenges in cleaner production and pollution control decision making. The case study has conducted at a representative steel making complex in Vietnam, simulating the material flows of water and waste streams, and energy balance (EB) for water production and wastewater treatment processes, by using STAN (subSTance flow ANalysis) and SANKEY software, respectively.

Ultrafiltration membrane was used to treat the effluent from textile industries. Crossflow ultrafiltration using GN polymeric membrane was used to remove the dye from textile effluent. A synthetic textile effluent of Direct-15 dye was used. The study focused through the effect of feed concentration, transmembrane pressure and solution’s pH on the permeate flux and percentage of dye removal were investigated. Dye concentration had significant effects on flux values. Under the fixed pressures and pH, the flux decreased while the dye rejection increased with increasing feed concentration.

Membrane bioreactors (MBRs) are being increasingly applied to many full-scale plants around the world to treat both municipal and industrial wastewater. However, membrane fouling and energy consumption are significant challenges to broader applications of MBRs. By using a new MBR configuration, this research aims to compare the performance between a conventional MBR and a reciprocation MBR (rMBR) that uses inertial forces without air scouring for fouling reduction.

Nitrophenols (such as o-nitrophenol (ONP), p-nitrophenol (PNP), and 2,4-dinitrophenol (DNP)) are priority environmental pollutants. Their toxicity is pH dependent, and these molecular species of nitrophenols exhibit higher toxicity than their anionic counterparts. Herein, for the first time, a method for the in situ measurement of nitrophenols in acidic industrial wastewater was developed using diffusive gradients in thin films (DGT) with lignocellulose hazelnut shell-derived activated carbons (HSACs) as the binding agents. Nylon membranes (0.1 lm rated) with diffusion coefficients of (2.

The internode of solid bamboo has significantly higher ash, 1% NaOH, alcohol- toluene and hot water solubles than the nodes [Mabilangan et al. 2002]. However, differences between the major chemical composition of node and internode fraction of bamboo are small [Scurlock 2000]; neither the number of nodes nor the length of internode segments would be critical to the utilization of bamboo for energy conversion, chemical production, or as a building material. Fujji et al. [1993] investigated the chemistry of the immature culm of a moso- bamboo (Phyllostachys pubescens Mazel).

To understand what motivates students to enrol in an MBA program, it is important to consider the perceived value of completing this degree. Research has focused on the career impact of the MBA and on specific skills acquired in the process of earning the degree. Some research has reported specific age and experience effects on the value of the MBA in skill acquisition and in career progression.

My point is not to encourage vandalism but to use it to query the effect that disability has on aesthetic appreciation. Vandalism modernizes art works, for better or worse, by inserting them in an aesthetic tradition increasingly preoccupied with disability. Only the historical unveiling of disability accounts for the aesthetic effect of vandalized works of art. Damaged art and broken beauty are no longer interpreted as ugly. Rather, they disclose new forms of beauty that leave behind a kitschy dependence on perfect bodily forms. ...

The volume of texting among teens has risen from 50 texts a day in 2009 to 60 texts for the median teen text user. Older teens, boys, and blacks are leading the increase. Texting is the dominant daily mode of communication between teens and all those with whom they communicate. The typical American teen is sending and receiving a greater number of texts than in 2009. Overall, 75% of all teens text. Here are the key findings about the role of texting in teens’ lives:  The median number of texts (i.e. the midpoint user in our sample) sent on a typical...

There is growing recognition among academics and practitioners that the risk and return characteristics of human capital—such as wage and salary profiles— should be taken into account when building portfolios for individual investors. Well-known financial scholars and commentators have pointed out the importance of including the magnitude of human capital, its volatility, and its correlation with other assets into a personal risk management perspective.2 Yet, Benartzi (2001) showed that many investors invest heavily in the stock of the company they work for.

One concern about the voluntary offset market as it continues to grow is the possibility that suppliers may sell the same reductions to multiple buyers, because there is no central authority to track their transactions. Related to this, questions can arise in some instances about who “owns” emission reductions and who in fact has the right to sell them. In some cases, multiple parties may conceivably lay claim to the same reduction.

Regulations of both home and host countries influence the choice of legal form of business model. Italian and Canadian banks, for example, are required to seek prior approval by their home regulator in order to open an overseas branch, and the Bank of Spain can refuse a bank’s application to open a branch on a wider set of criteria than in the case of subsidiaries (for EU-domiciled banks, these additional constraints do not apply for affiliate operations in EU member states given the EU single passport regime).
