Wastewater treatment. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it.
Sustainable energy management in the wastewater sector applies the concept of sustainable management to the energy involved in the treatment of wastewater. The energy used by the wastewater sector is usually the largest portion of energy consumed by the urban water and wastewater utilities. [1] The rising costs of electricity, the contribution ...
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. [ 2]
Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation ). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received. [ 1][ 2] ZLD technologies ...
Only a small fraction of nuclear fuel is consumed to generate electricity. Proponents of recycling envision reactors that use “reprocessed” spent fuel, extracting energy from the 90% of it ...
Bioremediation. The human sewage and the process waste from the manufacturing industries are the two major sources of the waste water. In Thailand, the total volume of the wastewater from industries is much greater than that of the domestic sewage. [2] As a result, an effective method is needed. Microbial remediation of xenobiotics has shown to ...
Electrocoagulation (EC) is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum ...
A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process. Generally, the biofilm is formed by a community of different microorganisms ( bacteria, fungi, yeast, etc.), macro-organisms ( protozoa, worms, insect's larvae, etc ...
