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 ...

ISO14001 Environmental Aspect Illustrated
An Industrial Effluent Treatment System (IETS) and Sewage Treatment System are delicate biotechnical equipment. Their biochemical dynamics often varies not according to mechanical equations that we prompt them to. Occasionally we encounter systems upset and expensive rectification work. Bulking, foaming and other symptom of ‘shock-loading’ are common challenges in IETS operation. ...

Characteristics and adsorption study of the activated carbon derived from municipal sewage sludge
Sewage sludge-based activated carbon is proved to be an efficient and low-cost adsorbent in treatment of various industrial wastewaters. The produced carbon had a well-developed pore structure and relatively low Brunauer-Emmett-Teller (BET) surface area. Adsorptive capacity of typical pollutants, i.e. copper Cu(II) and methylene blue (MB) on the carbon was studied. Adsorptions were affected ...

Evaluation of the energetic potential of sewage sludge by characterization of its organic composition
The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...

Acid dye removal from industrial wastewater by adsorption on treated sewage sludge
This study investigated the suitability of sewage sludge for the removal of Acid Blue 93 industrial wastewater. Washed sewage sludge (WS) and sludge activated carbon (AS) were used as adsorbents. The effect of pH, contact time, adsorbent dose and adsorption temperature was studied. Equilibrium isotherms for the adsorption were analysed by Freundlich and Langmuir isotherm models. The ...

Identification of industrial wastewater by clustering wastewater treatment plant influent ultraviolet visible spectra
A procedure is proposed which allows the detection of industrial discharge events at the inlet of a wastewater treatment plant without the need for measurements performed at the industry, for special equipment and for exact knowledge of the industrial sewage. By performing UV/Vis measurements at the inlet of a plant and analyzing them with a two-staged clustering method consisting of the ...

Current Situation and Future Development of Sludge Drying Treatment Technology
With the development of urbanization and social economy, the total annual sludge production in China continues to rise. As of January 2020, there are 10113 sewage treatment plants in China. The treatment capacity of urban sewage treatment plants nationwide is 177 million cubic meters per day, and the total sewage treatment capacity is 53.2 billion cubic meters. According to prospective estimates, ...

Towards a complete recycling of phosphorus in wastewater treatment – options in Germany
Global reserves of mineral phosphorus are finite and the recycling of phosphorus from wastewater, a significant sink for phosphorus, can contribute to a more sustainable use. In Germany, Switzerland, and the Netherlands, an increasing percentage of municipal sewage sludge is incinerated and the contained phosphorus is lost. This paper reviews current technologies and shows that a complete ...

Effect of earthworm loads on organic matter and nutrient removal efficiencies in synthetic domestic wastewater, and on bacterial community structure and diversity in vermifiltration
In this paper, we studied the effect of earthworm loads on the removal rates of chemical oxygen demand (COD), ammonia nitrogen (NH3-N), total nitrogen, and total phosphorus from synthetic domestic sewage and on the bacterial community structure and diversity of substrates in earthworm packing beds. The different vermifiltrations (VFs), including the control, are successful in removing both ...

How much cost to treat a ton of industrial wastewater
We all know that the quality of industrial wastewater is mainly inseparable from the production of factories. Different industries use different raw materials, so the resulting wastewater quality and cost are also different. Below we will focus on "How much cost to treat a ton of industrial wastewater" for a more detailed answer. The types of industrial sewage treatment are divided into petroleum ...

Recovery of reusable water from sewage using aerated flat-sheet membranes
Continuous developments and advances in membrane technology allow recovering to large extent reusable water from untraditional water sources, such as municipal effluents. In this paper, operational results and preliminary cost-analysis of a microfiltration (MF) process used for raw sewage and secondary effluent polishing are given. The research was conducted with a 22 sandwich-type flat-sheet ...

The sludge dryer can treat all kinds of sludge
Sludge is a collective term for various types of sediments and floating objects produced by different treatment processes in water supply and wastewater treatment. The composition and properties of the sludge mainly depend on the composition, properties and treatment process. According to different classification standards. There are many classification methods for sludge, which are briefly ...

Performance comparison between a two-reactor cascade and a single tank in an activated sludge wastewater treatment process
We investigate a model for the treatment of wastewater in the activated sludge process. The process is based on the aeration of wastewater with flocculating biological growth, followed by the separation of treated wastewater from biological growth. The biochemical model consists of two types of bacteria: sludge bacteria and sewage bacteria; and two types of ciliated protozoa: free-swimming ...

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 ...

Effect of phosphorus on nitrogen migration and transformation in deep subsurface wastewater infiltration systems
This paper investigates the effect of phosphorus on nitrogen migration and transformation during the sewage purification processes in deep subsurface wastewater infiltration systems. Good performance was achieved with a hydraulic loading rate of 0.1 m3/m2·d, indicating that the effluent water quality could meet the primary grade A values as put forth by the ‘Cities Sewage Treatment Plant ...

Sewage treatment plant
BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...
