Abstract:

Food production industry is the main producer of wastewaters with high fat, oil, and grease (FOG) content. FOG waste can be recovered from the wastewater stream by using physicochemical methods and reused considering their high methane potential. Popular method of FOG reuse is anaerobic co-digestion (AcoD) with wastewater treatment sludge and scum from the primary wastewater sedimentation tanks. This short review focuses on understanding the efficiency of FOG reuse possibilities by AcoD and takes a closer look at problems connected to degradation issues, gives an understanding on microbial cha

Abstract:

Catalytic wet peroxide oxidation (CWPO) is emerging as an advanced oxidation process (AOP) of significant promise, which is mainly due to its efficiency for the decomposition of recalcitrant organic compounds in industrial and urban wastewaters and relatively low operating costs. In current study, we have systemised and critically discussed the feasibility of CWPO for industrial and urban wastewater treatment. More specifically, types of catalysts the effect of pH, temperature, and hydrogen peroxide concentrations on the efficiency of CWPO were taken into consideration. The operating and maint

Abstract:

Wastewater in most countries of the Near East Region (NER) is being more and more recognized as of vital importance to be treated and made safe for reuse. It contributes considerably to the water budget in several countries, particularly those suffering from water scarcity. Treated wastewater is used directly in irrigation of farms or landscape green areas. Limited indirect use includes recharge of groundwater aquifers to control over-draft and salt intrusion in coastal areas. A large share of wastewater is still not treated and part of it is used in an uncontrolled manner, including for the p

Abstract:

Evaluating Urban Water-Energy Systems Based on UN Sustainable Development Goals (SDGs) Water, food, and energy are three of the major resource issues facing the world today. To help address these issues, urban wastewater is now being considered as a renewable resource than as a waste- a resource for water, for energy, and fertilizers. It is now well recognized that the traditional urban wastewater infrastructure needs to be re-engineered for improved environmental, social, and economic sustainability by minimizing the energy input for treating the wastewaters and by recovering water, energy, a

Originally designed for aquaculture, paddle wheel aerators have gained popularity in wastewater treatment because of their efficiency and inexpensive cost in shallow water settings. Paddlewheel aerators may be appropriate in decentralized, semi-urban, and small-scale operations, according to the article, which discu

Abstract:

The management of wastewater in the United States stands at a critical juncture, where aging infrastructure, evolving environmental challenges, and socioeconomic disparities converge to create a complex policy landscape. This paper investigates the intricate web of policies, regulations, and advocacy efforts shaping the future of wastewater management across the nation. It explores the effectiveness of foundational legislation such as the Clean Water Act and the Safe Drinking Water Act, while highlighting the persistent challenges faced by marginalized communities, where issues of environmenta

Abstract: Textile industry plays key role in any country for its basic needs and urbanization. Due to high demand in textile area, it generates massive amount of toxic wastewater. Generated wastewaters possess impurities and toxicity because of textile dyes containing complex organic chromophore groups. Direct release of wastewater creates lots of environmental issues. Treatments of textile effluent is not easily carried out by physical, chemical and biological methods without any affect. Nanoparticle mediated degradation trending presently but it contains metallic harmful effect so, further s

Abstract:

This paper provides an overview of regulatory issues related to wastewater treatment, the probable direction that future regulatory requirements will take, and any new technology needed to meet the anticipated requirements. Pressures for more stringent regulations governing wastewater treatment will probably come from environmental activists, a concerned public, global commitments to initiatives such as reductions of greenhouse gases or upper atmospheric ozone depletion, and from commitments to trading partners for a "level playing field" for environmental controls. The issues are concerned wi

The utilization of metal-based conventional coagulants/flocculants to remove suspended solids from drinking water and wastewater is currently leading to new concerns. Alarming issues related to the prolonged effects on human health and further pollution to aquatic environments from the generated nonbiodegradable sludge are becoming trending topics. The utilization of biocoagulants/bioflocculants does not produce chemical residue in the effluent and creates nonharmful, biodegradable sludge. The conventional coagulation–flocculation processes in drinking water and wastewater treatment, including
