Separation of toxic organic pollutants from industrial effluents is a great environmental challenge. Herein, an acid—base engineered foam is employed for separation of micro-oil droplets from an aqueous solution. In acidic or basic environments, acid—base polymers acquire surface charge due to protonation or dissociation of surface active functional groups.

This property is invoked to adsorb crude oil microdroplets from water using polyester polyurethane PESPU foam. The physicochemical surface properties of the foam were characterized using X-ray photoelectron spectroscopy, inverse gas chromatography, electrokinetic analysis, and micro-computed tomography.

Current World Environment

Using the surface charge of the foam and oil droplets, the solution pH 5. This optimal pH was verified through underwater wetting behavior and adsorption experiments. The droplet adsorption onto the foam was governed by physisorption, and the driving forces were attributed to electrostatic attraction and Lifshitz—van der Waals forces. The foam was regenerated and reused multiple times by simple compression.

The lowest trace oil content in the retentate was 3. This work lays the foundation for the development of a new class of engineered foam adsorbents with the potential to revolutionize water treatment technologies.

Vegetable cultivation is increasing because of its health benefit. However, in areas with limited fresh water, irrigation is from industrial and domestic wastewaters. Consumption of crops with high heavy metal content poses concern to health.

A comparative analysis was conducted using AAS Atomic Absorption Spectrophotometer to determine the concentration of heavy metals in some vegetables irrigated with industrial effluent, domestic wastewater, and water from natural dams in Kano State.

Cr and Ni had a mean significant difference within all the sites and Ni had mean value below the allowable limit, Cr only had below for natural site. The mean concentration for Mn and Cu were below the permissible limit and there was mean significant difference between natural and domestic sites for Mn but, there was none for Cu.

Vegetables cultivated from natural dams were relatively safe from contamination. The results highlight the need for the remediation of heavy metal contamination in irrigation waters from domestic and industrial sources to reduce the associated health hazards in the long run.

Back to Vol. Back to articles.A study was carried out in Malawi to assess the extent of chemical pollution in a receiving river as affected by industrial effluents. Both the effluents and the water at selected points in the river were analysed for pH, dissolved oxygen, biochemical oxygen demand, electrical conductivity, suspended solids, nitrate, alkalinity, hardness, chloride and phosphate in the dry and rainy seasons.

The results showed that the effluents were acidic in both the dry season range: 4. While the levels of dissolved oxygen, biological oxygen demand, electrical conductivity, suspended solids, alkalinity and chloride were relatively high in the dry and rainy seasons, the concentration of phosphate and nitrate were low in both seasons.

The water upstream was neutral average pH, 7. The water after the effluent receiving points was acidic and the levels of the other parameters were high, especially downstream. The results suggested that the water in the river was polluted and not good for human consumption.

It is therefore recommended that the careless disposal of the wastes should be discouraged and although the values in some cases were lower than the allowable limits, the continued discharge of the effluents in the river may result in severe accumulation of the contaminants and, unless the authorities implement the laws governing the disposal of wastes, this may affect the lives of the people.

A study was carried out in Malawi to assess the extent of chemical pollution in a receiving river as affected by industrial effluents. Both the effluents and the water at selected points in the river were analysed for pH, dissolved oxygen, biochemical oxygen demand, electrical conductivity, suspended solids, nitrate, alkalinity, hardness, chloride and phosphate in the dry and rainy seasons.

The results showed that the effluents were acidic in both the dry season range: 4. While the levels of dissolved oxygen, biological oxygen demand, electrical conductivity, suspended solids, alkalinity and chloride were relatively high in the dry and rainy seasons, the concentration of phosphate and nitrate were low in both seasons. The water upstream was neutral average pH, 7.

The water after the effluent receiving points was acidic and the levels of the other parameters were high, especially downstream. The results suggested that the water in the river was polluted and not good for human consumption. It is therefore recommended that the careless disposal of the wastes should be discouraged and although the values in some cases were lower than the allowable limits, the continued discharge of the effluents in the river may result in severe accumulation of the contaminants and, unless the authorities implement the laws governing the disposal of wastes, this may affect the lives of the people.

Water is also a vital resource for agriculture, manufacturing, transportation and many other human activities. Despite its importance, water is the most poorly managed resource in the world Fakayode, Ground and surface waters can be contaminated by several sources. In farming areas, the routine application of agricultural fertilizers is the major source Altman and Parizek, ; Emongor et al.

In urban areas, the careless disposal of industrial effluents and other wastes may contribute greatly to the poor quality of the water Chindah et al. A study on the impact of industrial effluent on water quality of a river carried out in Nigeria Fakayode, showed that the chemical parameters studied were above the allowable limits and also tended to accumulate downstream. The increasing demand on water arising from fast growth of industries has put pressure on limited water resources.

While most people in urban cities of the developing countries have access to piped water, several others still rely on borehole and river water for domestic use.

Most of the rivers in the urban areas of the developing world are the end points of effluents discharged from the industries. Industrial effluents, if not treated and properly controlled can also pollute ground water Olayinka, ; SARDC, Therefore, both bole holes and rivers generally have poor quality water in the affected areas.

Since people use untreated waters from these sources, the result is continuous outbreaks of diseases such as cholera, bilharzia, diarrhoea and others. Malawi, like other African countries, is experiencing rapid industrial growth and this is making environmental conservation a difficult task Kadongola, Although the government has put in place policies for effective environmental conservation and natural resources management, lack of political will is impeding their implementation.

This is also compounded by the fact that the industrial sector shifts the responsibility of pollution prevention to the government alone and this makes it difficult to prevent pollution.Views: College Osmania University, Hyderabad India. Hussain M, Prasad Rao T.

Curr World Environ ;8 3. Toggle navigation. In order to assess the surface water quality a total of forty two surface water samples were collected in pre-monsoon and post-monsoon seasons of, and were analyzed for electrical conductivity, pH, total dissolved solid, Na, K, Ca, Mg, HCO 3Cl, and SO 4.

However the three years of study shows that the surface water pollution in Bolaram and patancheru industrial development areas has significantly reduced, due to fact that the emission of effluents are treated regularly for the last few years.

Article Publishing History Received: Accepted: Introduction Surface water is usually rain water that collects in surface water bodies, like oceans, lakes, or streams. Surface water can become contaminated in many ways, one of which is direct recharge can come from industries sources. A change in the water chemistry due to surface water contamination can negatively affect all levels of an ecosystem.

It can impact the health of lower food chain organism and consequently the contaminated surface water can also affect the health of animals and humans when they drink or bathe in contaminated water or for aquatic organism when they ingest contaminated sediments. Degradation of water quality or depletion of water resources and loss of aquatic biodiversity are prominent features of the environmental landscape requiring urgent attention at global and national level.

Most of them use various inorganic and organic chemicals as raw materials. These industries discharging their waste effluents directly into the streams. The study area form the part of the Nakkavagu watershed.

Figure 1: The study area form the part of the Nakkavagu watershed. Apart from this, streams tanks both of medium and small size form the other surface water bodies of patancheru and bolaram industrial areas.

Mrs A. From outer space, the oceans are visible as great swirls of blue covering about 70 percent of the earth surface. The blue-white of ice snow covers another 3. Below the patches and linear clouds are lakes and rivers, ponds and streams; unseen beneath the surface are vast reservoirs of groundwater Speidel, Speidel states further that the earth is the only water world we know, the only planet where the compound water H2O exists as liquid, vapour and solid.

There appears to be only a very small set of conditions in any solar system where the three states of water can so exist. The change of water from one physical state to another in the hydrologic cycle is a major factor influencing the geological, chemical, physical and biological processes operating on the surface of the earth, including the development and maintenance of life.

Sometimes it may feel like there is an infinite supply of fresh water. Yet, available fresh water amounts to less than one-half of one Percent of all the water on earth. Water is life. Water is very essential to life, for without it, no life can survive whether man, animal or plant. It is a well-known fact that while man can do without solid food for more than 40 days; it is most unlikely that he can survive without water for 7 days.

Water is a natural resource of any country. With the fast growth in world population, the water resources of the world are becoming one of the most important assets. In the present age, the importance of water has further increased due to industrialization of the world as much potable water is needed for the production of many industrial goods, generation of hydropower and irrigation purposes etc. Water is also an important means of transportation in many parts of the world and a significant factor in recreation.

With the advancement in civilization, men has increased the rate of pollution of the much needed resource, making it unfit for so many uses. Sources and Distribution of Water Resources The primary sources of water include: rainwater, surface water stored in lakes, streams, and pondsand groundwater. The distribution of water, however, is quite varied; many locations have plenty of it while others have very little. Water exists on earth in three forms solid iceliquid or gas water vapour Shiklomanov, Oceans, rivers, clouds, and rain, all of which contain water, are in a frequent state of change Huntington, surface water evaporates, cloud water precipitates, rainfall infiltrates the ground, etc.

However, the total amount of the earth's water does not change; owing to glaciers, rivers and groundwater flow Shiklomanov, Figure 1 shows the global water occurrence and distribution. Of the small amount that is actually freshwater, only a relatively small portion is available to sustain human, plant, and animal life. The bar chart shows how almost all of Earth's water is saline and is found in the oceans.

In the first bar, only 2. The middle bar shows the breakdown of freshwater. Almost all of it is locked up in ice and in the ground.These metrics are regularly updated to reflect usage leading up to the last few days.

This work presents the procedures for monitoring volatile organic compounds during treatment of industrial effluents. The investigation was carried out for a specific effluent—caustic effluent from bitumen production.

The developed procedures enable more detailed control of the effectiveness of wastewater treatment than standard procedures. Caustic effluents from bitumen production have a complex physicochemical form and consist of an emulsion of an organic phase in a strongly alkaline aqueous phase.

The occurrence of an emulsified organic phase in the aqueous phase of the effluents results in their high toxicity toward the activated sludge of a refinery wastewater treatment plant as well as strong malodorousness. Interpretation of analytical results reveals that the effluents contain over organic compounds among volatile organic compounds VOCs alone. Using the developed procedures, of the VOCs were identified in raw postoxidative effluents.

The procedures described in this work allow detailed identification of VOCs as well as the determination of distribution of their concentrations for individual classes of chemical compounds. Monitoring changes in content of individual classes of VOCs, including highly malodorous volatile sulfur compounds, as well as changes in total VOC content, provides more information on the processes taking place during wastewater treatment.
