“…If the raw water pH value is below 7.0, it is necessary to add soda lime gradually. This neutralization process will form flocs much perfectly and can soften water hardness (Orooji et al, 2020). Flocculation coagulation begin with the addition of coagulant to the raw water, the colloidal particle destabilization process, and the flocculation process.…”

Raw water is natural water found in lakes, rivers, streams, and underground sources before any treatment or purification processes. It typically contains various impurities, such as suspended solids, organic matter, pathogens, and dissolved minerals, which need to be removed to make it safe for consumption. Aluminum Sulfate and Poly Aluminum Chloride (PAC) are two commonly used chemicals in the treatment of raw water to remove impurities and make it suitable for drinking, industrial, or agricultural purposes. These chemicals play crucial roles in the purification process by aiding in the coagulation and flocculation of contaminants, which facilitates their removal through filtration. Study on raw water treatment using Aluminum Sulphate and Poly Aluminum Chloride (PAC) coagulants was carried out at Talang Jawa IPA PDAM Lematang Enim of Muara Enim District by taking raw water samples from Talang Jawa Intake and Pelita Sari Intake. This study aimed to find out the right type and dose of coagulant in the raw water treatment process. he test parameters were turbidity and pH values. The research was conducted using a jar test to determine the dose of coagulant. The results showed the use of solid PAC was more effective for both intakes. The optimum coagulant dose is 20 ppm PAC in the raw water of Talang Jawa intake and Pelita Sari intake with turbidity of 2.62 NTU and 4.15 NTU and pH of 7.8 and 7.6.

“…Water used by hemodialysis machines because of the sensitive and dangerous effects it can cause for patients should be complementary treatment and without any contaminating elements ( 8 , 9 ). Based on results from different studies among dialysis patients, fatal fever-causing reactions, production of endotoxin and infection are the most current complications of microbial contamination of water in hemodialysis instruments ( 8 , 10 , 11 ).…”

Dialysis water is vital because of various harmful contaminants for patients. The aim of this study was to assess the efficiency of hemodialysis instruments in the removal of microbial and chemical pollutant in educational hospitals affiliated to Ahvaz Jundishapur University of medical sciences, Iran during 2018–2019. This cross-sectional descriptive research studied the microbial and chemical water quality of hemodialysis instruments in Razi, Sina, and Golestan hospitals in Ahwaz, Iran. 72 samples of microbial parameters and 24 samples of chemical parameters were collected from water used in hemodialysis instruments, including microbial characteristics (the total coliform, fecal coliform and heterotrophic bacteria counts) and chemical characteristics (pH, turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC) at Razi, Imam, and Golestan educational hospitals on all weekdays during 2018-2019. In this study, experiments were done according to the current standard methods, EPA from hemodialysis instruments. Finally, using SPSS18 software and descriptive statistics, the relationship between results at the removal of toxic, microbial, and chemical pollutants in different months and hospitals was investigated. this study showed that the average concentration of chemical characteristics during the warm season at Razi, Imam, and Golestan educational hospitals for pH, Turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC were (6.867, 6.4475, 6.53); (2.985, 3.035, 1.226); (0.075, 0.245, 0.195); (38.5, 21.965, 144.87); (1.552, 1.657, 39.445); (8.6, 4.5, 21.5), (2.09, 3.187, 78.975); (0.0082, 0.038, 0.155), and (125.25, 70.35, 78.35), respectively during 2018. Also, during 2019, results showed that the average levels of amounts for pH, Turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC in Razi, Imam, and Golestan educational hospitals were (7.077, 7.252, 6.435), (1.725, 0.595, 4.16), (0.0775, 0.0597, 0.0297), (52.33, 138.81, 20.92), (23.52, 18.227, 8.767), (35, 27.25, 4.05), (14.58, 28.152, 9.25), (0.0067, 0.0045, 0.0032), and (210.52, 121.62, 29.16), respectively. According to the results, hemodialysis instruments in Razi and Imam have a 90% efficiency in removing heterotrophic bacteria counts (HPC). Based on these findings, educational hospital hemodialysis equipment effluent in Ahvaz, Iran was mitted to Iran environmental standards for use in hemodialysis machines. The result showed that the removal percentage level of microbial and chemical pollutants by the hemodialysis process is comparatively suitable. It should be mentioned that in the proper operation and reconstruction, hemodialysis systems can have an increased rate of removal of microbial and chemical pollutants.
