Contaminants in plating wastewater are hard to remove, especially hexavalent chromium ions. This waste stream contains a large amount of Cr6+, a highly toxic metal, potential to cause cancer. To reduce this pollution, sludge from a supply water treatment plant (DWTS) has been used to make adsorbent.

In this study, a composite material (ACS) was successfully synthesized from activated carbon (AC) derived from soybean curd and sludge from the supply water treatment process using FeCl3. Subsequently, the ACS was employed as a heterogeneous catalyst for the degradation of Paracetamol (PRC) in solutions under conditions of the Fenton process.

This study evaluated the performance of a laboratory-scale inverse fluidised bed reactor (IFBR) for biological selenate reduction at 30◦C. The IFBR with floating biomass carriers was fed with synthetic mine water (pH 6.0–7.0) containing ~10 mM (1.4 g L− 1 ) selenate, nutrients and 10 mM ethanol as electron donor and inoculated with selenate reducers enriched from anaerobic sludge and environmental samples.

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.

Aquatic pollution occurs due to the discharge of harmful substances, chemicals or microorganisms into water bodies i.e. a stream, river, lake, ocean, aquifer, or other body of water resulting in contamination & degradation of water quality and rendering it unsuitable for human use or the environment. Many advanced water treatment techniques are followed before discharging this polluted water into the surrounding environment. However some limitations is there. In this context, Biofilms have become the important part of biological treatment of municipal waste water.

The purpose of this study was to modify the sludge from DWTP as a low-cost adsorbent for adsorption of phosphate in wastewater. The absorption performance of MS was examined, and the removal mechanisms were elucidated. The finding of this study is helpful for further development of a low-cost adsorbent based on sludge from DWTP to remove P in wastewater and offers a solution reduce water treatment sludge production and disposal fees also.

Petroleum oil sludge resulting from crude oil storage, illegal crude oil refining and bunkering activities constitutes environmental hazards and pollution in the crude oil producing communities in the Niger Delta region of Nigeria. Biostimulation with N.P.K. fertilizer option C, bioargumentation with indigenous hydrocarbon utilizing bacteria (HUB) option B, combination of biostimulation and bioaugmentation as option A and option D was without any bioremediation treatment were employed in the bioremediation of brackish water artificially polluted with petroleum oil sludge.

Field experiment was conducted at University of Agricultural Sciences, Bangalore with an objective to enhance productivity of finger millet intercropping in organic system of production during Kharif 2006 and 2007. Different organic manures at 50 kg N equivalent used in the experiment are Farm yard manure (FYM), sewage sludge, poultry manure compost (PMC), urban garbage compost, enriched urban garbage compost and vermicompost (VC) compared to inorganic fertilizers alone. Irrigation water was provided during dry spells throughout the crop growth period.

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).

Sewage sludge as an uncalled for product of wastewater treatment poses the challenge to society of disposing of it, but at the same time gives us the opportunity of beneficial use by closing the cycle of nutrients: sludge derived from agricultural activity must return to soil if a sustainable and ecologically sound management of these materials is desirable (SEQUI et al. 2000). At present the major ways of disposing of sewage sludges are deposition, landfill and incineration, only part of the sludges are used in agriculture. ...

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.

Pot and field trials were carried out using sediment dredged from the port of Bremen (Germany) and deposited in a settling basin near Bremen; the sediment is polluted with Cd and Zn. Five iron-bearing materials were added to the soil (1% pure Fe in soil dry matter) to immobilize the heavy metals: ‘Red mud from the aluminium industry, sludge from drinking-water treatment, bog iron ore, unused steel shot and steel shot waste.
