Special Issue Information

Dear Colleagues,

For over a century, wastewater collection and treatment have been focusing on pollution control and reduction. This conventional approach has commonly been accepted by water industry as the practical means of achieving the objective of managing our water resources. Although being able to meet the intended objectives, this conventional approach has faced challenges such as intensive energy consumption, waste generation, etc., during the treatment processes. It fits into a framework of a “linear” economy model.  However, in the current energy-climate era, the desire to achieve sustainability in development has motivated the water industry to pursue greener approaches involving a “circular” economy concept. Under the “circular” economy framework, water engineering professionals should move away from the framework of a “linear” economy model that is unsustainable and resource intensive and adopt a new mindset whereby “wastes” are considered as resources. New concepts, technologies, processes, designs and operating principles should be explored and developed so that we can manage wastewater in a more sustainable way. The professionals should thus explore the concept of “circular” economy, which helps to promote sustainable development and effective resource utilization in water industry.

Therefore, we organized this Special Issue to discuss wastewater pollution control with a focus on sustainability in the world including, but not limited to, sustainability issues in the water industry faced by the world, advanced wastewater collection and treatment technologies and practices, and how to incorporate the circular economy concept in wastewater collection and treatment systems to better achieve sustainable development.

Submissions for this Special Issue could relate, but are not limited, to the following topics:

  • Advanced wastewater collection and treatment systems;
  • Water pollution and sustainability;
  • Energy, heat and resource recovery;
  • Water reclamation and reuse;
  • Circular economy in water industry;
  • Emerging issues relating to wastewater management.

Due to the progressing problems with ensuring sufficient quantity and quality of water for municipal, irrigation and economic purposes, the pressure to reuse treated wastewater is increasing. This fact forces the development of advanced systems enabling more effective wastewater treatment. This article presents the results of a 2.5-year study period in which compost beds, which are part of a natural treatment system for wastewater (NTSW), were used to treat domestic sewage by fully removing easily degradable organic matter and by fully nitrifying ammonium nitrogen. It was shown that the compost environment provides complete access to oxygen for the coexisting heterotrophic and autotrophic bacteria, covering 100% of their oxygen demand. Moreover, the outflow of treated wastewater shows an oxygen content of 4–7 g O2/m3. Advanced biological oxidation occurring in the compost beds with an area of 1 m2 per inhabitant and a daily hydraulic load of about 100 L/m2 can effectively and without additional energy expenditure provide a 98% reduction in biological oxygen demand and a 99.5% reduction in ammonium nitrogen. In addition, the effluent from the compost filters meets the most stringent quality criteria for (1) treated wastewater used for irrigation and (2) bathing water in terms of microbiological contamination.

At this time, efforts are being made on a worldwide scale to accomplish sustainable development objectives. It has, thus, now become essential to investigate the part of technology in the accomplishment of these Sustainable Development Goals (SDGs), as this will enable us to circumvent any potential conflicts that may arise. The importance of wastewater management in the accomplishment of these goals has been highlighted in the study. The research focuses on the role of fourth industrial revolution in meeting the Sustainable Goals for 2030. Given that water is the most important resource on the planet and since 11 of the 17 Sustainable Goals are directly related to having access to clean water, effective water management is the most fundamental need for achieving these goals. The age of Industry 4.0 has ushered in a variety of new solutions in many industrial sectors, including manufacturing, water, energy, healthcare, and electronics. This paper examines the present creative solutions in water treatment from an Industry-4.0 viewpoint, focusing on big data, the Internet of Things, artificial intelligence, and several other technologies. The study has correlated the various concepts of Industry 4.0 along with water and wastewater management and also discusses the prior work carried out in this field with help of different technologies. In addition to proposing a way for explaining the operation of I4.0 in water treatment through a systematic diagram, the paper makes suggestions for further research as well. Full article
