Paper Review

This paper review research works on BOD/COD ratio toxicity to three bioindicators, namely: Daphnia magna, Artemia salina, and Brachydanio rerio. Treatment methods are divided into natural, biological, physical, chemical, combined treatment, and phytotechnology for various types of processing operations such as municipal and industrial wastewater treatment plants, various effluent treatment, landfill leachate, and organic matter. A. salina shows the lowest toxicity value of the BOD/COD ratio and shows it can withstand processing conditions that are not biodegradable. Then followed by B. rerio and D. magna. Furthermore, the disposal limits are standardized for the protection of freshwater biota. In addition, it must be considered whether there is any other potential of disposal into the receiving environment, and if so, what form of disposal and how much, to protect the biota.

Characterization Methods

Excess sludge generated from wastewater treatment plants (WWTPs) can cause negative impacts on human health, water bodies, aquatic plants, and soil quality. However, the produced sludge could be appropriately managed to obtain various economic and environmental benefits. One of the feasible and practical options of sludge management is the synthesize of biochar via oxygen-limited pyrolysis. The use of biochar adsorbent for pollutant removal offers various advantages such as high adsorption capability, low operating and chemical costs, no production of toxins. Hence, this study addresses the applications of sewage sludge-derived biochar for industrial wastewater treatment. The methods of sludge collection, drying, pulverization, and pyrolysis are illustrated. Biochar characterization methods (SEM, EDX, XRD, and FTIR analyses) and mechanisms of the adsorption process are described. The sludge-derived biochar could be used as an adsorptive material for industrial effluent treatment. Recommendations for future studies that could enhance the adsorption capacity of biochar and modified-biochar are given.

More than fifty wastewater treatment plants worldwide (representing several millions p.e) are equipped with up-flow biofiltration reactors (BioforR). Their range of application encompasses municipal as well as industrial wastewater. A summary of the results achieved in a large number of plants is presented, accompanied by a description of the operating parameters and the treatment limitations with regard to various pollutants (C, N, P). The separation of functions into specific reactors combined with optimized wash conditions guarantees high treatment efficiency.

Exposure Pathways

The tremendous increase in the production and consumption of titanium dioxide (TiO2) nanoparticles (NPs) in numerous industrial products and applications has augmented the need to understand their role in wastewater treatment technologies. Likewise, the deleterious effects of wastewater on the environment and natural resources have compelled researchers to find out most suitable, economical and environment friendly approaches for its treatment. In this context, the use of TiO2 NPs as the representative of photocatalytic technology for industrial wastewater treatment is coming to the horizon. For centuries, the use of industrial wastewater to feed agriculture land has been a common practice across the globe and the sewage sludge generated from wastewater treatment plants is also used as fertilizer in agricultural soils. Therefore, it is necessary to be aware of possible exposure pathways of these NPs, especially in the perspective of wastewater treatment and their impacts on the agro-environment. This review highlights the potential exposure route of TiO2 NPs from industrial applications to wastewater treatment and its impacts on the agro-environment. Key elements of the review present the recent developments of TiO2 NPs in two main sectors including wastewater treatment and the agro-environment along with their potential exposure pathways. Furthermore, the direct exposure routes of these NPs from production to end-user consumption until their end phase needs to be studied in detail and optimization of their suitable applications and controlled use to ensure environmental safety.
