مدیریت تلفیقی سوسری آمریکایی Periplaneta americana (L.) در شبکه و تاسیسات جمعآوری فاضلاب در شهر بوشهر
Background and Objective: The sewer system is one of the important and suitable areas for the growth and reproduction of American Cockroach Periplaneta americana (L.) in Bushehr. This project was implemented for considering the high cost of spraying and environmental pollution. Materials and Methods: In this study some commonly insecticides were tested in different doses to evaluate the effect...
متن کاملChemical and biological technologies for hydrogen sulfide emission control in sewer systems: a review.
Biogenic corrosion of sewers represents a cost of about 10% of total sewage treatment cost in Flanders (Belgium) and is further increasing. In the past, research has resulted in a number of prevention methods, such as injection of air, oxygen, H(2)O(2), NaClO, FeCl(3) and FeSO(4). The possibility of biological oxidation of sulfide using nitrate as the electron acceptor has also been explored in...
متن کاملA New Image Model for Predicting Cracks in Sewer Pipes based on Time
Sewer overflows may cause communities to be vulnerable to various health problems and other monetary losses. This puts a lot of burden on responsible to minimize end user complaints. Therefore, crack prediction would be helpful to facilitate decision makers to control sewer overflow problems and prioritize inspection and rehabilitation needs . The accurate prediction of current underground sewe...
متن کاملHow Delft-FEWS incorporates real-time sensor data with dynamic modeling to allow Real Time Control of sewer systems
We discuss how Delft-FEWS is applied to incorporate real-time sensor data and dynamic modeling to allow Real Time Control (RTC) of three sewer systems in the area of the Hoeksche Waard, the Netherlands. The purpose of this project was to reduce sewerage spilling to the surface water by optimizing the available storage in the sewer systems. In this paper we will present how Delft-FEWS makes use ...
متن کاملOptimum Design of Sewer Collection Networks
Various methods have been used to economically design wastewater and stormwater collection systems. In this article, Discrete Differential Dynamic Programming (DDDP) which is a subsection of dynamic programming (DP) was used. For each pipe network, various alternatives such as depth and slope of pipe laying and various diameters could be considered to satisfy hydraulic and engineering constrain...
