The ultimate disposal of wastewater sludge (biosolids) continues to be one of the most difficult and expensive problems in the field of wastewater engineering. Wastewater treatment plants generate different sludges, like ...

In recent years, discharges of the organic solvents have been subjected to stringent environmental regulations because of their undesirable effect on living organisms in aquatic environments and human health. Organic ...

As a principle "recycling should be preferred over treatment wherever possible". In line with this, a multipurpose Mechanical Vapor Recompression (MVR) evaporator pilot plant was designed, fabricated and tested at a pilot ...

Contamination of the subsurface by organic compounds in the form of non-aqueous phase liquids (NAPL) is a major threat to groundwater resources. Many of these compounds are characterized by low water solubility and are ...

The use of ultrasound in environmental applications is a novel advanced oxidation process that is currently being investigated as a method to degrade refractory organic wastes, which can not be degraded by conventional ...

Industrial effluents and high-strength wastewaters such as landfill leachates may contain significant amounts of heavy metals. The presence of heavy metals causes toxicity in biological treatment systems. The toxic and ...

Dyehouse effluents are highly colored and contain significant amounts of dissolved and suspended solids so that in most cases the use of membrane separation technologies as a final treatment stage becomes inevitable to ...

The growing reliance on synthetic polymers has raised a number of environmental and human health concerns. Most plastic materials are derived from nonrenewable resources and not biodegradable. Their distinguishing properties ...

Life cycle management is very essential to sustainable development which aims a balance between environmental, social and economic dimensions over products’ life cycle. Life cycle management consists of methods to quantify ...

Chemical oxidation techniques have been used in water treatment for the removal of natural organic matter, which produce halogenated organic compounds upon chlorination. Although being a powerful oxidant, ozone is known ...
