“…According to Rommens’ study (19), a remarkable difference existed in the present study, that is, pH value average increased by 0.11 after the MS-PFI treatment. Rezania et al (20) indicated that a tiny growth in pH that ranges from 6.95 to 7.1 during an Eichhornia crassipes purification system. Some researchers considered that a decline of pH may drive by acid secretion from plant roots, and degradation of organic matter by aerobic organisms (21).…”

13A multilayer solar planted floating island (MS-PFI) planted with Eichhornia 14 crassipes are potential alternatives to traditional PFI. The highest removal rates of 15 suspended solids, total nitrogen, total phosphorus, ammonia nitrogen and chemical 16 oxygen demand was 86%, 75%, 80%, 95% and 84%, respectively. Proteobacteria 17 (average 43.4% of total sequences) and Actinobacteria (19.9%) were the dominant 18 phyla. Numerous genus had obvious differences between influent and effluent water, for 19 instance, 13, 12 and 7 % in effluent water were assigned to the hgcl_clade, 20Norank_c_Cyanobacteria, and Rhizorhapis, while their relative abundances were 21 decreased to 5, 3 and 0 %. In contrast, a distinct increase among Flavobacterium (10%), 22Limnohabitans (7%), Alpinimonas (4%), norank_p_Saccharibacteria (4%), Erwinia (3%) 23 after MS-PFI treatment. MS-PFI brings various bacteria involved in contaminant 24 degradation and nutrient removal in biological wastewater treatment systems. An 25 amount of ¥ 1,843 was totally inputted to construct floating bed, which was rarely 26 needed operation and maintenance costs. 27Importance 28In-situ micro-polluted water ecological remediation, microorganisms and plants are 29 effective to improve environmental quality and provide essential ecosystem services. 30Recently, we invent a new multilayer solar with an excellent pollutant removal 31 efficiency.

About 11% reduction efficiency for TDS was observed by [10] while treating the domestic wastewater using Eichhornia crassipes. However, reduction of 26% for TDS was reported by [12] in Eichhornia crassipes.…”

Abstract. The efficiency of Eichhornia crassipes for treatment of raw kitchen wastewater was studied in the present research work. An artificial wetland of 30 liter capacity was created for phytoremediation of kitchen wastewater using Eichhornia crassipes. Kitchen wastewater samples were collected from hostel of an educational institute in India. Samples were characterized based on physical and chemical parameters such as pH, turbidity, total hardness, nitrate-nitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid. The physico-chemical parameter of kitchen wastewater samples were analysed for durations of 0 (initial day), 4 and 8 days. After 8 days of retention period, it was observed that pH value increases from 6.25 to 6.63. However, percentage reduction for turbidity, total hardness, nitratenitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid were found to be 74.71%, 50%, 78.75%, 60.28%, 25.31%, 33.33%, 15.38% and 69.97%, respectively. Hence water hyacinth (Eichhornia crassipes) is found efficient and easy to handle and it can be used for low cost phytoremediation technique.

“…Under appropriate environmental conditions, WH may double its biomass through asexual reproduction within two weeks; ten WH plants can produce 655,360 new plants in eight months, and they can cover the water surface by about half a hectare [7]. The WH's excessive amount and its expansive growthresulted in to interfere with shipping, irrigation and electricity generation [8]. In Selorejo dam, Malang, East Java, Indonesia, 100 hectares of the total reservoir area of 650 hectares is covered by WH.…”

Thermogravimetric analysis experiment to understand thermal decomposition behavior of water hyacinth during the pyrolysis has been performed. Water hyacinth was taken randomly from 2 places, i.e., Selorejo and Sengguruh Dam, district of Malang, Indonesia. Those raw materials were thoroughly cleaned by using the water, then cut and dried in an oven with a temperature range of 80-90 o C for 6 hours. Subsequently, the dried samples were crushed and then filtered to a mesh size of 60. Thermal behavior of the sample was observed through the instrumentality of thermal analyzer at a constant heating rate of 10 °C/min with a nitrogen flow rate of 100 ml/min and a temperature range of 25-1000 °C. The kinetics of active pyrolysis zone were evaluated by Coats-Redfern integral method. The thermogravimetric test results show that the water hyacinth biomass decomposed into four stages during the pyrolysis process. The kinetic parameters in term of activation energy (E), logarithmic frequency factor (log A) and reaction order (n) were 60.74 kJ/mol, 4.77/min and 1.9, respectively.
