Eggshell Waste

The exemplary properties of eggshell waste have gained a lot of attention due to its chemical composition and bio-degradable features making it a suitable choice to be used in wastewater treatment. The use of biosorption as an alternate treatment technology to conventional processes such as chemical precipitation and ion exchange is seen as a promising solution to the many drawbacks experienced by conventional processes. Furthermore, due to higher imposed environmental legislations, eco-friendly and low-cost considerations have set the momentum in the search for biosorbents of this nature. With the circular economy being the focal point of industrial operations, eggshell waste is a highly promising biosorbent due to its non-toxicity properties and its ability to be converted from a waste material to a valuable product. In this review paper, fundamental aspects of biosorption will be discussed where the main focus will lie in qualitatively examining the properties of eggshell waste, binding mechanisms, kinetics and isotherm modelling that make it an attractive option to be used in the biosorptive process. Finally, a summary of the important considerations for future research work in this field is presented.

Selecting the best wastewater treatment (WWT) technology requires a thorough qualitative and quantitative evaluation of multi-dependence criteria. A network based method is one of the many possible techniques that able to handle multi-dependence criteria in the selection. This paper proposes relative importance weights of alternatives in selecting the WWT technology using the analytic network process (ANP) in Terengganu Malaysia. The ANP is applied to establish the relative weights of alternatives based on criteria and sub-criteria that available in the WWT technology selection. Two faculty members attached to a public university and an engineer in Malaysian government agency were interviewed to provide evaluation within the framework of ANP. Inner dependence and outer dependence analysis of ANP are fully utilised to establish relative importance weights of alternatives. The experiment result reveals that the relative importance weights of the three alternatives are 0.3074, 0.2795 and 0.2447. The alternative ‘Composting’ has decided as the most suitable technology in WWT which provides the highest relative importance weight among all the three alternatives. The results would be a great significance for the practical implementation of the WWT technology selection.

One of the key roles of water quality scientists and engineers is to develop affordable wastewater treatment systems, as efficient as required by applicable legislation, error and nuisance free, environment-friendly, fault-tolerant and easy to operate. The concepts of affordability and appropriateness are considered. A number of “classic” errors in the implementation of supposedly low cost treatment systems are outlined. Finally the features of three successful types of treatment technology are described.

Atrazine Degradation

Atrazine is a kind of triazine herbicide that is widely used for weed control due to its good weeding effect and low price. The study of atrazine removal from the environment is of great significance due to the stable structure, difficult degradation, long residence time in environment, and toxicity on the organism and human beings. Therefore, a number of processing technologies are developed and widely employed for atrazine degradation, such as adsorption, photochemical catalysis, biodegradation, etc. In this article, with our previous research work, the progresses of researches about the treatment technology of atrazine are systematically reviewed, which includes the four main aspects of physicochemical, chemical, biological, and material-microbial-integrated aspects. The advantages and disadvantages of various methods are summarized and the degradation mechanisms are also evaluated. Specially, recent advanced technologies, both plant-microbial remediation and the material-microbial-integrated method, have been highlighted on atrazine degradation. Among them, the plant-microbial remediation is based on the combined system of soil-plant-microbes, and the material-microbial-integrated method is based on the synergistic effect of materials and microorganisms. Additionally, future research needs to focus on the excellent removal effect and low environmental impact of functional materials, and the coordination processing of two or more technologies for atrazine removal is also highlighted.

Metals Removal

Finding affordable and environment-friendly options to decontaminate wastewater generated with heavy metals and dyes to prevent the depletion of accessible freshwater resources is one of the indispensable challenges of the 21st century. Adsorption is yet to be the most effective and low-cost wastewater treatment method used for the removal of pollutants from wastewater, while naturally derived adsorbent materials have garnered tremendous attention. One promising example of such adsorbents is hydrogels (HGs), which constitute a three-dimensional polymeric network of hydrophilic groups that is highly capable of adsorbing a large quantity of metal ions and dyes from wastewater. Although HGs can also be prepared from synthetic polymers, natural polymers have improved environmental benignity. Recently, cellulose-based hydrogels (CBHs) have been extensively studied owing to their high abundance, biodegradability, non-toxicity, and excellent adsorption capacity. This review emphasizes different CBH adsorbents in the context of dyes and heavy metals removal from wastewater following diverse synthesis techniques and adsorption mechanisms. This study also summarizes various process parameters necessary to optimize adsorption capacity followed by future research directions.
