Using Natural Systems for Industrial Wastewater Treatment ...

The use of anammox-like processes is relatively new to the wastewater world and has garnered much attention. But there is a “however”, and that is that scientific understanding has been slow to make inroads to the engineering world; let alone the world of natural treatment systems.

(PDF) NATURAL MEANS OF TREATMENT OF WASTEWATERS

Unlike organic pollutants, metals in wastewaters are not degraded through biological processes, threatening not only the aquatic ecosystems but also human health through contamination of drinking water [7].Several studies have shown that natural and constructed wetlands are very effective in removing heavy metals from polluted wastewaters.

[PDF] Ammonium removal from wastewaters using natural New ...

Abstract Ammoniacal nitrogen (ammonia and ammonium) in agricultural wastewaters can promote eutrophication of receiving waters and be potentially toxic to fish and other aquatic life. Zeolites, which are hydrated aluminum‐silicate minerals, have an affinity for ammonium ions (NH4 +) and are, therefore, potentially useful in removing this contaminant from wastewaters.

Removal of heavy metal ions from wastewaters using natural ...

A bentonite sample from the Petreş ti deposit, Cluj County (Romania), was used to remove heavy-metal ions (Cd 2+, Pb 2+, Cr 3+) from wastewaters.A representative sample of bentonite (P) was characterized using the Brunauer-Emmett-Teller (BET) method, wet chemical analyses, X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) spectroscopy.

Batch investigations on P immobilization from wastewaters ...

Sep 01, 2013  Phosphorus from wastewaters and sediment flux to surface water represents a major source of lake eutrophication. Active filtration and in situ capping (which refers to placement of a covering or cap over an in-situ deposit of contaminated sediment) are widely used as a means to immobilize phosphorus from wastewaters and sediment, to mitigate lake eutrophication.

Wastewater - Wikipedia

Wastewater is any water that has been contaminated by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration". Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities. The characteristics of wastewater vary ...

Industrial wastewater treatment - Wikipedia

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.. Most industries produce some wastewater.Recent trends have been to minimize such production or ...
