Drinking water quality control: control charts for turbidity and pH
Water treatment processes are required to be in statistical control and capable of meeting drinking water specifications. Control charts are used to monitor the stability of quality parameters by distinguishing the in-control and out-of-control states. The basic assumption in standard applications of control charts is that observed data from the process are independent and identically ...

WaReg protects homes from flooding in Sweden - Case Study
Location: Backaryd, Sweden Customer: Backaryds Vattenverk Problem: Backaryd Water Treatment plant backwash their filters regularly. During this process water is released into the town sewer network at a rate of 16 l/s. The towns sewer network is dimensioned to cope with 5 l/s so when it receives 16 l/s it becomes problematic for downstream residents. When the backwashing occurs, homes in the ...

Membrane processing for water treatment in the semiconductor industry
It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology plays a special role atseveral ...

Monitoring of reservoir feed for hydrocarbon contamination - Case Study
APPLICATION Monitoring of rural watercourse feeding a small reservoir to detect contamination from farm or food processing facilities. CUSTOMER Water Company, SW England PROBLEM Persistent small contamination events had put the reservoir which feeds a drinking water treatment plant at risk. Low level contamination preceded a large event in late ...

Problematic algae in the sedimentation and filtration process of water treatment plants
Problematic algae, species that do not settle or are not easily removed by water treatment processes, are common in many water treatment plants (WTPs). We recorded algae in the water that overflowed from sedimentation basins (SBs) to filtration basins of WTPs in South Korea. Diatoms were common and other algae were not discernible in the flocs. Our field observation indicated that long and ...

Application of ELM to predict the coagulant dosing in water treatment plants
Predicting the coagulant dosage is especially crucial to the purification process in water treatment plants, directly affecting the quality of the purified water. Nowadays, several mathematical methods have been adopted for the purification process, but their predictive precision and speed still need to be improved. This study applies a novel neural network called the extreme learning machine ...

Control-design methodology for drinking-water treatment processes
The performance of a drinking-water treatment plant is determined by the control of the plant. To design the appropriate control system, a control-design methodology of five design steps is proposed, which takes the treatment process characteristics into account. For each design step, the necessary actions are defined. Using the methodology for the pellet-softening treatment step, a new control ...

water treatment plant header lateral for filtration
The water treatment plant is a facility that processes and purifies water for drinking, irrigation, and other uses. One of the most important components of a water treatment plant is the header lateral for filtration. Header lateral filtration is a process used in water treatment plants to remove suspended solids, such as algae and sediment, from the water. Filtration processes are like this: The ...

The essential role of water in industry: challenges and solutions
Today, finding an industry that does not operate with water is difficult. This resource is used, to a greater or lesser extent, in all industries, regardless of their purpose. All industrial activity requires water to produce its end products or to support production activities. Whether for the construction of cars, waste management, or food production. However, water consumption ...

Desalination of oil sands process-affected water and basal depressurization water in Fort McMurray, Alberta, Canada: application of electrodialysis
The high content of inorganic species in water used to extract bitumen from the Alberta oil sands and in the groundwater below the oil sands is an increasing environmental concern. These water matrices require treatment before they can be reused or safely discharged. Desalination of the oil sands process-affected water (OSPW) and groundwater, or basal depressurization water (BDW), can be ...
