Abstract
Sewage water is a mixture of water and solids added to water for various uses, so it needs to be treated to meet local or global standards for environmentally friendly waste production. The present study aimed to analyze the new Maaymyrh sewage treatment plant's quality parameters statistically at Hilla city. The plant is designed to serve 500,000 populations, and it is operating on a biological treatment method (Activated Sludge Process) with an average wastewater inflow of 107,000m3/day. Wastewater data were collected daily by the Mayoralty of Hilla from November 2019 to June 2020 from the influent and effluent in the (STP) new in Maaymyrh for five water quality standards, such as (BOD5), (COD), (TSS), (TP) and (TN). The results showed that the removal efficiency was 88%, 75%, 94%, 57%, and 77%, respectively. The results of the cluster analysis (CA) showed the formation of clusters in four stages and then gave the final shape consisting of two groups. At the same time, two influencing factors were extracted in the principal component analysis (PCA). The effluent's final quality (an average of eight consecutive months) complies with the stringent regulations proposed in the Iraqi Quality Requirements.
Highlights
There is a great deal of spatial and temporal variability in the availability of water in Iraq
The present study aims to assess the Mayoralty STP's sewage quality located in Babil Governorate in Iraq using the principal component analysis and cluster analysis
4.1 Raw sewage assessment Characteristics of sewage entering the treatment plant is shown in Table 3, which shows the changes in the properties of raw sewage over time, Total suspended solids (TSS), Chemical oxygen demand (COD), biological oxygen demand (BOD), NO2, NO3, Total nitrogen (TN), Total Phosphorous (TP)
Summary
There is a great deal of spatial and temporal variability in the availability of water in Iraq. The amount and consistency of supplies coming from various sources influence the quality of water. In order to maintain our knowledge and understanding of our climate, overall national planning and resource management in relation to water with emphasis on the allocation of priorities among different uses is important (Vaux, 2001). It is commonly used in many research publications relating to the needs of sustainable development (Parparov et al, 2006)
