literature review on dairy wastewater treatment

The milk processing industry is one of the world's staple industries, thus the treatment possibilities of dairy effluents have been attracting more and more attention. The purpose of the paper is to review contemporary research on dairy wastewater. ...

The purpose of the paper is to review contemporary research on dairy wastewater. The origin, categories, as well as liquid by-products and general indicators of real dairy wastewater are described.

In this review article, it is briefly discussed about the processes in the dairy industry and work done in such processes, amount of wastewater and, major sources of wastewater as well as the harmful effects of wastewater on the environment.

This review aims to shed light on developing the technologies used in dairy factories and the most prominent integrated technologies to achieve the highest efficiency in the extraction processes of dairy derivatives and dairy wastewater treatment.

Abstract Dairy industry is one of the leading consumer of water and producer of wastewater. Increased demand of dairy products results in rapid growth of dairy industry and hence wastewater production increases. Dairy effluent contains high concentrations of organic and inorganic substances that cause eutrophication in water bodies. This review study emphasizes on various treatment methods of ...

In the following review, both dairy and soybean industries were investigated for the quality of their wastewater, treatment processes and potential applications. The goal of this review was to compare the treatment technologies and opportunities for recycling of the wastewater from two key food industries: dairy and soy.

This review article aims to critically examine and describe pre- and post-treatment techniques for dairy wastewater treatment.

The treatment techniques that are most suitable for dairy wastewaters are presented and discussed. Wastewaters from the dairy industry have chemical substances that can be recovered and reused in industrial products or may even constitute new products.

possibilities of dairy effluents have been attracting more and more attention. Th. purpose of the paper is to review contemporary research on dairy wastewaters. The origin, categories, as well as ...

This review study emphasizes on various treatment methods of DWW for period 2002 to 2022. Dairy wastewater imposes serious environmental concern because of the presence of wide range of fatty acids, proteins, nutrients, and other organics. These contaminants are difficult to treat in single step conventional treatment technique.

Numerous studies have been conducted to date to considerably reduce the adverse effects of these wastewaters [24]. Physicochemical processes are widely used for treatment of industrial wastewaters. Summarised literature of the dairy industry wastewater treated with physico-chemical processes are given in Table 3.

The study shall review the literature available on wastewater treatment technologies used in dairy industry and predict areas for future studies. One of the areas studied is the removal of antibiotic resistant bacteria from the wastewater effluent.

This study demonstrates the application of an algae-assisted microbial fuel cell (AMFC) in biogas upgradation. A proof-of-concept lab-scale biorefinery is presented that couples raw biogas upgradation with dairy wastewater treatment using an integrated approach of a bicarbonate-based integrated carbon capture and algae production system (BICCAPS) and a microbial fuel cell (MFC). The treated ...

This review delves into the crucial role of enzyme-producing microorganisms in enhancing AD efficiency for dairy wastewater treatment, emphasizing their potential benefits and addressing the economic and environmental considerations associated with this approach.

A summary of data for two-phase anaerobic dairy wastewater treatment practices in literature is given in Table 4. Initial results for two-phase anaerobic treatment of a dairy wastewater were reported from pilot plant studies [117].

Abstract Considerable research has been conducted on the treatment of dairy wastewater by anaerobic granular reactors. Upflow anaerobic sludge blanket (UASB) reactors, anaerobic sequencing batch reactors (ASBR) and static granular bed reactors (SGBR) are the conventional granular reactor types most commonly applied in dairy wastewater treatment.

Dairy industry is one of the most polluting industries in India. Due to the elevated milk demand, the dairy industry in India has developed swiftly, leading to a large amount of waste discharge in the nearby water bodies. The waste water from dairy industry is...

Among the food industries, dairy industry is most polluting in regards to its large water consumption because water has been a key processing medium. Environmental protection agencies have started a strict vigil for banning of wastewater discharge into the natural resources of water. This has made the water treatment more expensive thereby becoming a huge burden for the industries. Thus, water ...

To meet discharge limits, dairy wastewater must be treated before discharge. It can be either discharged along with other wastewaters into municipal wastewater treatment plants (WWTPs) or treated on site if dairy plants have their own WWTP. As conventional wastewater treatment systems are used, a large volume of solid organic wastes is generated.

Versatile applications of freshwater and marine water microalgae in dairy wastewater treatment, lipid extraction and tetracycline biosorption Sequential cultivation of microalgae in raw and recycled dairy wastewater: microalgal growth, wastewater treatment and biochemical composition

Because of these issues, we present in this review, a brief discussion on the risk associated with the untreated wastewater exposures and advanced methods for its treatment, reuse possibilities of the treated wastewater in agriculture.

The present literature review consisted in research papers published in journals, full papers presented at conferences, master thesis and PhD dissertations addressing the characteristics and the treatment of wastewater generated by dairy industries in the state of Minas Gerais, Brazil.

This review will examine the type and composition of waste produced by dairy industries, its treatment and proper utilization. Especially, it focusses on biotechnological alternatives to utilize it. The aim of this review is to provide the latest source of information on dairy waste treatment and utilization. 2.

The dairy industry can contribute to global food security in a sustainable way by efficiently converting milk into dairy ingredients and products, even though they are polluting on a large scale. In this context, this study aimed to conduct a systematic literature review on sustainable indicators and dairy industries. The methodology used has a qualitative and quantitative approach and its ...
