“…High values of EC could cause increase in blood pressure which can affect kidneys also. Current investigation was in agreement of the research conducted to reduce pH, EC and heavy metals in waste water with the help of Moringa oleifera treatment (34). Hardness is due to the mineral contents of water specially calcium and magnesium and their sum are considered as hardness of water.…”

The proposed work was carried out to replace the conventional water purification methods by natural coagulants. Samples of groundwater were obtained and analyzed for quality parameters. The coagulants of Moringa oleifera, orange peels, and date pits were prepared, and different combinations of these coagulants were used to find out the most effective one. Results regarding various physicochemical tests including pH, electrical conductivity, turbidity, total dissolved solids (TDS), calcium, magnesium, total hardness, bicarbonates, chlorides and heavy metals revealed that pH was not affected by treatments, values for EC were dropped down slightly but not reduced to an acceptable limit of World Health Organization (WHO). TDS, total hardness and chlorides reduced to the acceptable limit of WHO. Additionally, a significant reduction was recorded in lead and arsenic contents of treated water samples. Moreover, the results exhibited that the values for TPC and Total Coliform were dropped down slightly but not reduced to a satisfactory limit of WHO, while fecal Coliform reduced to the acceptable limit of WHO and E.coli was found to be zero in all samples. Conclusively, natural coagulants contain good adsorbent properties, which can confer the purification of water in a cost-effective way.

This research aimed to investigate the performance of seeds extract of Moringa Oleifera (MO) as an eco-friendly coagulant and an alternative practice in enhancing primary domestic wastewater effluent treatment by coagulation/flocculation, and sedimentation. The seeds of Moringa Oleifera were dried, crushed, and sieved, the content of oil was extracted with n-hexane as a solvent employing soxhlet apparatus (electro thermal) then used the residue as domestic wastewater coagulant. Jar tests were conducted for improve the primary treatment of domestic wastewater effluent from the wastewater plant of Ain Aouda city, Rabat, Morocco. For this reason, perform of coagulation tests was comparative with using aluminium sulphate (alum). Moringa Oleifera seeds extract at the optimal dose of 250 mg/L shows encouraging results, by comparison with the use of alum (150 mg/L). In reality, in terms of TSS reduction 95.5% and 96.8%, while turbidity reduction 97.5% and 98.1% were obtained for MO seeds extract and alum, respectively. But, the reduction rate of COD and BOD of Alum was somewhat higher than that of MO seeds extract 81.8% and 76.8% for COD, while were 75.5% and 72% for BOD respectively. Differently from alum, observed that increase in the extract of MO seeds dosage happened a slight change in pH value, decrease conductivity, and three times less bulky quantity of sludge than alum. For avoiding the numerous disadvantages associated with the use of chemical coagulants, the usage of Moringa Oleifera seeds extracts is recommended.

One of the major needs in human life is water. Some communities in the town of Pasuruan still use well water for cooking and drinking. Based on previous studies it is known that five samples of well water in the town of Pasuruan containing Pb above the maximum limit water requirements based on Regulation of the ABSTRAKSalah satu kebutuhan utama dalam kehidupan manusia adalah air bersih. Sebagian masyarakat kota Pasuruan masih menggunakan air sumur untuk masak dan minum. Berdasarkan penelitian sebelumnya diketahui bahwa lima sampel air sumur di kota Pasuruan mengandung logam Pb di atas batas maksimum persyaratan air bersih berdasarkan Peraturan Menteri Kesehatan Nomor 416/MENKES/PER/IX/1990. Salah satu metode sederhana yang bisa menurunkan kandungan logam Pb dalam air adalah koagulasi. Tujuan penulisan adalah : 1) mendapatkan data koagulan yang bisa menurunkan kandungan logam Pb; 2) memperoleh efisiensi koagulan; 3) merekomendasikan koagulan yang bisa digunakan untuk mengolah air sumur mengandung logam Pb. Penulisan ini menggunakan metode deskriptif kuantitatif dengan pengambilan data dari studi kepustakaan. Penulisan dilakukan dalam empat tahap : 1) mencari data hasil analisa laboratorium sampel air sumur; 2) membandingkan hasil analisa dengan persyaratan air bersih; 3) mencari koagulan yang bisa digunakan untuk menurunkan kandungan logam Pb dalam air; 4) mengkaji efisiensi koagulan. Hasil kajian menunjukkan bahwa : 1) koagulan yang bisa digunakan untuk menurunkan kandungan logam Pb adalah : a) air laut; b) serbuk biji kelor; c) serbuk eceng gondok teraktivasi 2%; d) alum 20 mg/L dan 1250 mg/L; e) FeCl3; 2) efisiensi koagulan air laut mencapai 95,5%, serbuk biji kelor mencapai 95,6%, serbuk eceng gondok teraktivasi mencapai 96%; alum 20 mg/L mencapai 36%, alum 1250 mg/L mencapai 67%; FeCl3 mencapai 84%; 3) koagulan yang bisa digunakan untuk mengolah lima sampel sumur adalah air laut, serbuk biji kelor, serbuk eceng gondok teraktivasi NaOH 2%, dan FeCl3 1000 mg/L. Kata kunci: air, bersih, Pasuruan, Pb, sumur PENDAHULUANAir bersih merupakan kebutuhan utama bagi kehidupan manusia. Kualitas kehidupan manusia bisa dilihat dari air bersih yang digunakan.
