Coagulation Process

Chemical oxygen demand (COD) in domestic wastewater can be treated using flocculation-coagulation process with addition of Oyster mushroom (Pleurotus ostreatus) in powder form as biocoagulant. The fungal cell wall of Oyster mushroom comprises of chitin that is high polyelectrolyte and can be function as an absorbent of heavy metals in wastewater. The effectiveness of flocculation-coagulation process in treating wastewater depends on dose of coagulant and mixing rate. Therefore, this study aims to determine the best combination of three variation of dose of biocoagulant which are 600 mg/l, 1000 mg/l, and 2000 mg/l and mixing rate which are 100 rpm, 125 rpm, and 150 rpm that give the most reduction of COD in the wastewater. The result indicates that the combination of 1000 mg/l of biocoagulant and 100 rpm of mixing rate were found to be the most optimum combination to treat COD in the wastewater with COD reduction of 47.7%.

The Impact

<p>The objective of the study is to determine accumulation and translocation of heavy metals from soil to paddy straw irrigated with urban sewage wastewater in peri-urban region of Girudhumal subbasin area in Madurai. The soil samples were collected in seven locations irrigated with treated and untreated wastewater and analyzed for physical properties like pH, EC, bulk density, soil type, major (N,P,K) and micronutrients (Fe, Mn, Cu, Zn) and heavy metals Ni, Cd, Pb. SEM analysis showed that soil structure is significantly influenced by wastewater irrigation. It confirms that the wastewater irrigation disturbs soil structure and affecting the plant growth in long run.&nbsp; Pb content was higher than the prescribed safe limits in S5 and S6 location, similarly, Ni also was higher than the safe limit in all the locations. Pollution Load Index values are in the range of 0.08-0.56 for all sites, and it indicated that chance of heavy metal contamination is less. The EF values show moderate enrichment to Ni and Zn, Significant enrichment for Cd and Cu, Extremely high for Pb and deficiency for Mn. All these results confirmed that there is no immediate risk of heavy metal pollution, however with respect to Pb and Ni the plant tissues are showing higher values. The transfer factor for heavy metals from soil to paddy straw is less than 0.5 for Cd and for others is more than 0.5 indicated greater chances for heavy metal contamination.</p>

Mushrooms are a source of nutrition particularly in respect of proteins and vitamins. It has been rightly called “vegetable meat”. Apart from being potential protein and energy source, mushrooms are famous for their medicinal values. In addition to their fascination for the gourmet, they are nature’s most active agents in the disposal of forest’s waste materials. Not only in disposing timber, but also helps in converting dead plants into available food. They are efficient agents, fitting into the nutrient cycle of farms and forests. As they utilize agricultural by products and wastes as their substrate, mushroom cultivation is an eco-friendly activity. In a country like India where vegeterians dominate, every attempt should be made to popularize a vegetable protein source like mushroom. A study on the cultivation of oyster mushroom, Pleurotus florida was undertaken. It was found to grow on various solid wastes viz. paddy straw, rice husk, saw dust, water hyacinth and a mixture of all the selected substrates. The oyster mushroom cultivated on the paddy straw gives the maximum yield with high content of protein, carbohydrate and lipid.

The research work carried out investigated the influence of various substrate sterilization methods and days of spawn maturity on the growth characteristics of Pleurotus sajor-caju, grey oyster mushroom. The paddy straw substrate was sterilized by various sterilization methods such as chemical sterilization, boilingwater sterilization and steam sterilization. The spawn of the mushroom produced were used at three different days of maturity viz. 25 days, 35 days and 45 days. The substrate and spawn inoculated beds were maintained at defined environmental conditions in the mushroom cultivation chamber and the growthperformance were monitored and the characteristics were recorded. The study revealed that the steam sterilized substrate and the 35 days old spawn gave the maximum yield compared to the beds inoculated with substrates sterilized with other two methods of sterilization and spawn of 25 days and 45 days old. Theresults gave a reliable information regarding the preference of the substrate sterilization method and the days of spawn maturity for the cultivation of the Pleurotus sajor-caju, grey oyster mushroom.
