  • The growth of waterborne pathogens and the discharge of partially treated or non-treated chemical waste has become a severe environmental and health risk. Conventional wastewater treatment methods have become less effective, and most current techniques require multiple stages for the disinfection of antimicrobial-resistant (AMR) pathogens and the combined removal of toxic, non-biodegradable, or emerging priority pollutants from wastewater.

  • The solution of paracetamol and sildenafil (Penagra) was effectively sensed using modified carbon paste electrodes. LNPs showed a good photocatalytic activity (PCA) for Orange Red (OR) dye under UV light irradiation. These results indicate that the synthesized LNPs are a good candidate for displays, waste water treatment and for the use as electrochemical sensors.

  • Petrochemical is the fastest growing industry, also manufacturing variety of chemicals. However the waste generated during the manufacturing is a major environmental concern due to its persistence in soil and water bodies. An alternative to chemical treatment is bioremediation which aims to enhance the normal processes of microbial degradation and clear the pollutant from the environment.

  • Bagasse is a cheap material and the collection of bagasse is easy from sugarcane shops. This survey used cane bagasse as a substrate for aerobic biological modeling to treat aquatic waste water, bringing about economic, technical and environmental benefits. This study was conducted at three different loads: 1.2kg COD/m3 .day; 2.4kg COD/m3 .day; 3.6kg COD/m3 .day. The results showed that COD removal efficiency was 99.15%, the optimum load of the research model was 2.4kg COD/m 3 .day for the SS removal efficiency reaching 92.49%.

  • The presence of chlorine in alternative fuels (e.g., sewage sludge, municipal solid waste or incineration ash, chlorinated biomass,) has both direct and indirect implications on cement kiln emissions and performance. Methods have been developed to properly manage chlorine and its potential implications – but it is important that these implications be recognized and managed. Trace levels of chlorine in feed materials can lead to the formation of acidic gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF) (WBCSD 2002).

  • This section illustrates that MBT systems can be described as two simple concepts: either to separate the waste and then treat; or to treat the waste and then separate. In some systems only biological treatment is required to treat all the residual MSW before disposal to landfill. Whilst a variety of treatment and mechanical separation options are offered, these need to be optimised in terms of the outputs in order to find outlets for the various materials / fuels derived from the process (see Markets for the Outputs section). ...

  • In many developed nations, significant progress has been made in reducing direct discharges of pollutants into water bodies, primarily through increased treatment of industrial wastewater before it is discharged. An OECD report found that in member countries in the past several decades, “industrial discharges of heavy metals and persistent chemicals have been reduced by 70-to-90 percent or more in most cases” (OECD 2006). In developing countries, on the other hand, more than 70 percent of industrial wastes are not treated before being discharged into water (UN- Water Statistics).

  • Wastes are very process-specific but the key pollutants can be derived from knowledge of: the process, construction materials, corrosion / erosion mechanisms and maintenance materials. Waste audits are used to gather information on the source, composition, quantity and variability of all wastes. Waste prevention typically involves preventing the arising of waste at source, minimising the arisings and recycling any waste that is generated.

  • The objective of waste water treatment is to prevent large quantities of substances to reach and impact the environment in high doses and concentrations. Areas of high population densitiy naturally are areas were production of sewage sludge is high (see Figure 1-1). Presently about 8 million t of sewage sludges (MAGOAROU 2000) are produced each year in the EU member states (Table 1-1). Its high content of organic materials, of nitrogen and phosphorous suggest their use as soil conditioner and fertilizer in agriculture.

  • The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues....
