The Wastewater Treatment Process
What is Wastewater? Wastewater is classified as used water from any combination of domestic, industrial, commercial, agricultural activities, surface runoff, or storm water. The wastewater treatment process removes the contaminants from the wastewater and converts it into an element that can be returned to the water cycle with minimum impact on the environment. Water can carry harmful diseases ...

Wastewater Treatment Process
The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

Hospital Wastewater Treatment Process
1. The characteristics of hospital sewage Hospital waste water contains some special pollutants, such as drugs, disinfectants, diagnostic agents, detergents, and a large number of pathogenic microorganisms, parasite eggs and various viruses (such as roundworm eggs, hepatitis virus, tuberculosis and dysentery) . In addition, there are radioactive substances such as radium 226, phosphorus, gold ...

The Solution of Papermaking Wastewater Treatment Process
Papermaking wastewater is an important factor in polluting water sources, and it is also a kind of industrial pollution source. Therefore, it is particularly important to realize the cleaning and resource utilization of the papermaking production process.The papermaking wastewater mainly comes from pulping wastewater from pulping workshops and papermaking wastewater from papermaking ...

Cavitational technology in wastewater treatment process
Cavitation is one such recent technique which has been found to be substantially beneficial in wastewater treatment. Cavitation can be described as formation, growth and sub-sequent collapse of cavities releasing large magnitudes of energy locally, creating conditions similar to hot spots, and also generating strong oxidizing conditions by way of production of hydroxyl radicals and also hydrogen ...

Removal of Cryptosporidium by wastewater treatment processes: a review
Cryptosporidium is a protozoan parasite that infects humans and various animal species. The environmental stability and the low infectious dose of Cryptosporidium facilitate its transmission by water and food. Discharge of untreated wastewater may result in waterborne or foodborne Cryptosporidium outbreaks, therefore a suitable treatment may prevent its dissemination. Most studies on ...

Research on a soft measurement model of sewage treatment based on a case-based reasoning approach
In this paper, the measurement of biochemical oxygen demand (BOD) in a wastewater treatment process is analyzed and an intelligent integrated prediction method based on case-based reasoning (CBR) is proposed in order to overcome difficulties. Due to the fact that there are many factors that influence the accuracy of the prediction model, the radial basis function, which is a neural network ...

Bayesian modeling of virus removal efficiency in wastewater treatment processes
Left-censored datasets of virus density in wastewater samples make it difficult to evaluate the virus removal efficiency in wastewater treatment processes. In the present study, we modeled the probabilistic distribution of virus removal efficiency in a wastewater treatment process with a Bayesian approach, and investigated how many detect samples in influent and effluent are necessary for ...

Treatability and fate of various phosphorus fractions in different wastewater treatment processes
The increasingly more stringent phosphorus (P) discharge limits, which are below the concentrations reliably achievable with currently available technologies, demand for better understanding of phosphorus removal mechanisms. This study investigated the compositional fractions of phosphorus (P) in various effluents as well as the efficacy of different levels of treatment processes for removing ...

Aerobic wastewater treatment processes history and development synopsis
A Synopsis by the Author This book is an overview of the development of aerobic waste water treatment and influences which shaped this development. The historical development of sewage treatment and the subsequent emergence of aerobic biological treatment methods is investigated from the early nineteenth century to the present day. In addition, the earlier historical background, up to the ...

The use of response surface methodology for modelling and analysis of water and wastewater treatment processes: a review
In recent years, response surface methodology (RSM) has been used for modelling and optimising a variety of water and wastewater treatment processes. RSM is a collection of mathematical and statistical techniques for building models, evaluating the effects of several variables, and obtaining the values of process variables that produce desirable values of the response. This paper reviews the ...

Preliminary and Primary Treatment of Wastewater (or Sewage)
is the first of the three distinct steps involved in traditional sewage treatment plants. Primary wastewater treatment is the first of three treatment phases that follow pre-treatment. In fact, the wastewater treatment process consists of three phases: primary treatment, secondary treatment and tertiary treatment. Here’s a quick look at sewage primary treatment process ...

ENHANCING THE PERFORMANCE OF OXIDATION DITCHES
Oxidation ditches are very popular wastewater treatment processes for small to mediumsized municipalities that have to meet stringent water quality standards. Oxidation ditches provide cost-effective treatment while requiring relatively simple operational skills. Because carbonaceous BOD removal, nitrification, and de-nitrification can be accomplished within a single reactor, the process can ...

Energy consumption model for wastewater treatment process control
Wastewater treatment must satisfy discharge requirements under specified constraints and have minimal operating costs (OC). The operating results of wastewater treatment processes (WWTPs) have significantly focused on both the energy consumption (EC) and effluent quality (EQ). To reflect the relationship between the EC and EQ of WWTPs directly, an extended Elman neural network-based energy ...

Survival of Helicobacter pylori in the wastewater treatment process and the receiving river in Michigan, USA
Contaminated water may play a key role in the transmission of Helicobacter pylori, resulting in gastrointestinal diseases in humans. The wastewater treatment process is an important barrier to control the transmission of H. pylori. However, the presence and viability of H. pylori in the treatment process is not well known. In this paper, the real colony morphology of H. pylori was confirmed ...
