Biogeography and Assembly of Microbial Communities
Scientific understanding of microbial biogeography and assembly is lacking for activated sludge microbial communities, even though the diversity of microbial communities in wastewater treatment plants (WWTPs) is thought to have a direct influence on system performance. Here, utilizing large-scale 16S rRNA gene data generated from 211 activated sludge samples collected from 15 cities across
Based on the optimization perspective, taking shortcomings of Fenton process as a breakthrough, the fundamentals, advantages and disadvantages of single Fenton optimization processes (heterogeneous Fenton, photo-Fenton and electro-Fenton) for organic wastewater treatment were reviewed and the corresponding reaction mechanism diagrams were drawn
Water and Wastewater Treatment: Historical Perspective
Water and Wastewater Treatment: Historical Perspective of Activated Carbon Adsorption and its Integration with Biological Processes Prof. Ferhan Çeçen Bogazici University, Inst. of Environmental Sciences, 34342 Istanbul, Turkey
This paper aims to review the development of wastewater treatment operation and control over the last two decades. Due to the authors' background and experiences there is a special emphasis on the Scandinavian perspective.
Pulp Mill Wastewater: Characteristics and Treatment
The typical pulp mill wastewater treatment should include primary treatment (neutraliza- tion, screening or sedimentation), principally to remove suspended solids, and biological/ secondary treatment.
Volume 1 (Wastewater characteristics, treatment and disposal) presents an integrated view of water quality and wastewater treatment, analysing waste-water characteristics (flow and major constituents), the impact of the discharge into receiving water bodies and a general overview of wastewater treatment and sludge treatment and disposal.

Wastewater treatment facilities have become sin quo non in ensuring the discharges of high quality wastewater effluents into receiving water bodies and consequence, a healthier environment. Due to massive worldwide increases in human population, water has been predicted to become one of the scarcest resources in the 21st century, and despite large advances in water and wastewater treatments
Wastewater treatment and reuse in urban agriculture
Reutilization of nutrients and water from domestic treated wastewater to urban agriculture is often considered as a potential food–energy–water–health (FEW–health) nexus strategy that may use energy and increase GHG emissions, while advancing water cycling and nutrient recovery, and also providing access to fresh/healthy foods (Hanjra et al 2015, Makoni et al 2016).
From the beginning of the Bronze Age (ca. 3200–1100 BC), domestic wastewater (sewage) has been used for irrigation and aquaculture by a number of civilizations including those that developed in China and the Orient, Egypt, the Indus Valley, Mesopotamia, and Crete. In historic times (ca. 1000 BC−330 AD), wastewater was disposed of or used for irrigation and fertilization purposes by the
Conservation‐Induced Wastewater Flow Reductions Improve
Abstract: Water resources are under increasing pressure to meet potable supply needs while sustaining aquatic ecosystems and fisheries. Growing populations and enforcement of the Total Maximum Daily Load provisions of the Clean Water Act present public water and wastewater utilities with costly options to meet potable water demands and reduce pollutant discharges into receiving waters.
6 Century-Scale Perspective on Water Quality in Selected River Basins of the Conterminous United States nitrogen applied to agricultural fields doubled from 0.5 to 1.0 million tons per year and by 1989, it reached 10 million
- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
- How many types of polyaluminium chloride are there?
- There are four types of polyaluminium chloride for sale for water treatment, specifically PAC 30% 01&02. The other types, PAC 30% 03 and PAC 28% 04, are used for industrial wastewater treatment. The four types can be easily distinguished by color, from white to light-yellow and deep-yellow.
