Key Factors

Bamboo charcoal (BC) as an environmentally friendly and low-cost material receives widespread attention. Recently, much attention has been focused on the use of BC as adsorbent to treat wastewater. This paper provides an overview of the adsorption of organic contaminants in solution by using BC. The sorption behaviors of BC with various organic pollutants, and the kinetic model adopted to explain the adsorption rate of organic pollutants from aqueous solution were also reviewed. The adsorption capacity, the isotherm model, and several key factors such as modification, surface area, are discussed in this paper. Possible improvement of BC to treat organic contaminants in aqueous solution is also proposed.

The Cost

Sonolysis is emerging as an effective advanced technology for destruction of organic pollutants in wastewater. The focus of this study is to investigate the potential of enhancing the sonochemical destruction of aqueous organics. Increasing the contaminant destruction rate will reduce the reaction time, and possibly reduce the cost of treatment. For this purpose, the effect of H2O2 and/or silica in the presence of ultrasound is examined for destruction of 2-chlorophenol (2-CP). The effect of silica dosage (1, 5, 10, and 20 g/L), peroxide dosage (50, 75, and 100 mg/L), and pH (3,7,and 11) is examined. Low solution pH provided higher destruction of 2-CP. The presence of peroxide or silica enhanced the destruction of 2-CP. The optimum silica dosage was 5 g/L. 100 mg/L of peroxide and 5 g/L of silica present together enhanced 2-CP sonolytic destruction by a factor of approximately 2 as compared to 2-CP destruction with ultrasound only.

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants (POPs) into the atmosphere, including polychlorinated biphenyls, dioxins, and furans. The circumstances of exposure are detailed in Part 1, Background and Policy Issues. An ecologically based, staged health risk assessment was conducted in two parts with two levels of government as sponsors. The first, called the Swan Hills Study, is described in Part 2. A subsequent evaluation, described here in Part 3, was undertaken by Health Canada and focused exclusively on Aboriginal residents in three communities living near the lake, downwind, and downstream of the SHSWTC of the area. It was designed to isolate effects on members living a more traditional Aboriginal lifestyle. Aboriginal communities place great cultural emphasis on access to traditional lands and derive both cultural and health benefits from “country foods” such as venison (deer meat) and local fish. The suspicion of contamination of traditional lands and the food supply made risk management exceptionally difficult in this situation. The conclusion of both the Swan Hills and Lesser Slave Lake studies was that although POPs had entered the ecosystem, no effect could be demonstrated on human exposure or health outcome attributable to the incident. However, the value of this case study is in the detail of the process, not the ultimate dimensions of risk. The findings of the Lesser Slave Lake Study have not been published previously and are incomplete.
