study of powdered carbons for waste water treatment

Study of Powdered Carbons for Waste Water Treatment

The objective of the present study was the characterization of commercial and experimental carbons to select those best suited for municipal waste water treatment and to determine properties responsible for high adsorptive capacity for organic pollutants, high rate of adsorption, and ease of remov- al by settling.

Where to dose powdered activated carbon in a wastewater

1. Introduction. Wastewater treatment plants (WWTP) are considered as the main point source of organic micro-pollutant (OMP) emissions into the aquatic environment as numerous OMP such as pharmaceuticals or industrial chemicals are not or only partly removed in WWTP (Jekel et al., 2015, Michael et al., 2013, Oulton et al., 2010, Reemtsma et al., 2006, Verlicchi et al., 2012a).

Pyrolytic valorization of water treatment residuals

This study investigated the possibility of applying pyrolysis as an alternative method to recycle powdered activated carbon-containing water treatment residuals (PAC-WTRs) discharged from the Cheongju water treatment plant as a multifunctional adsorbent. WTRs pyrolyzed for 1 h at 200–700 °C were compared with raw material.

Activated Carbon and Water Treatment - Water Quality

Drinking water treatment facilities employ a host of technologies to convert “raw” water from rivers, lakes and underground sources into safe, potable water. At the treatment plant, these technologies are applied in a particular order, known as a “treatment train,” to produce water of optimum quality for the consumer. This article focuses on one of

The landfill functions as both a waste treatment bioreactor and a leachate treatment bioreactor. Aerobic landfills recycle the leachate which is treated by the aerobic bacteria. As the waste stabilized using aerobic treatment, metal concentrations were significantly reduced, while no appreciable difference were found when the waste was stabilized anaerobically [ 69 ].
