Structural and Nitrogen amendments of Paper mill wastes are basic necessity at the initial decomposition stage for making it palatable to earthworms as well as for effective vermicomposting. This experiment was conducted for finding out the requirement of minimum possible time for initial aerobic decomposition of waste paper based paper mill wastes amended with saw dust and cow dung, either alone or in combination during its vermicomposting using Eisenia fetida earthworms. It was found that the amendment of Paper Mill waste with saw dust and cow dung in 1:0.5:0.5 ratio when processed through initial aerobic decomposition at least for 14 days with two turnings at 7 days interval, became very suitable for growth and survivability of earthworms and produced nutrient rich best quality vermicomposts which ultimately supported good growth of paddy seedlings. More turnings of bed materials help to reduce the concentration of heavy metals in vermicomposts through leaching loss. Addition of saw dust and cow dung as structural amendments with paper mill wastes increases both primary and secondary nutrients in vermicomposts prepared using Eisenia fetida earthworms.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78117812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, disposal of the high TDS reject RO water is a concern. The conventional methods used for disposal of RO reject water are expensive and not environmental friendly. Herein, the present study is an attempt to grow Salicornia brachiata using RO reject water; this approach provides a sustainable solution for utilizing RO reject water. The optimum plant growth was observed when irrigated with RO reject water (A-type) having TDS of 26511-27102 ppm. Additionally, the biomass of plants was found moderately better when treated with A-type reject water compared to the plants irrigated with high saline water (sea water) having TDS of similar range i.e., 27511-28010 ppm TDS. The highest values of succulence (phylloclade diameter) coincide with the growth optimum. The optimum inflorescence length was noted in A-type RO reject water and sea water treated plants. The moisture content in the plants was insignificantly different at different TDS. On the other hand, the short height plants were developed with less number of branches and biomass, when treated with A-type RO reject water having F concentration of 25 and 50 mg/L, The test results of phylloclade for F- was found in the range of 0.09-0.12 mg/100 gm DW indicates that S. brachiata is F- tolerant plant. Therefore, the finding suggest that cultivating S. brachiata plant as a vegetable in greenhouse using RO reject water with and without F- is potential as well as environmental friendly solution for reject water management.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"79 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73772606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different initial concentrations of chromate anions from 0 to 145 ppm were added as K2Cr2O7 to 1 g of modified zeolite adsorbent. Zeolite (clinoptilolite, Z) was also used for comparison reasons. The kinetic analysis of both adsorbents (Z, Z1) was studied at 25°C. Equilibrium isotherms of chromate anions were studied for clinoptilolite and modified zeolite at 25, 40 and 60°C. According to the kinetic analysis, the chromate anions adsorption capacity reached at 1115.10 mg Cr (VI)/kg adsorbent for Z1 and 35.05 mg Cr (VI) kg for Z. According to isotherms, the adsorption of Cr (VI) on Z1 and Z did not increase with the increase of temperature indicating that the whole adsorption mechanism is controlled by chemisorption and not by physical adsorption. Modified zeolite and zeolite were tested to two different soils, i.e. a soil amendments. The modification of clinoptilolite with HDTMA-Br leads to the creation of positively charged surface sites of zeolite increasing the adsorption of Cr (VI) as chromate anions. Such adsorbents can be applied for the removal of heavy metals and dyes in an anionic form from wastewater and soil solutions where negative charged sites of clinoptilolite present low adsorption capacity.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81705907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing rates of urbanisation has increased environmental stresses, emphasising the importance of environmental protection. Sewage treatment is the most effective method to improve water quality. However, a recent increase in the sewage treatment rates has not improved the overall water quality in China. Data collected from the China Statistical Yearbooks has shown that there has been an increase in sewage treatment rates, particularly in larger cities. With 3350 wastewater treatment facilities ranging from super large facilities that can cater to a population of 1 million, to small facilities that cater to smaller populations of less than 100 000. The overall water quality remained low due to the unavailability of wastewater pipelines to connect to the WWTP. Possible ways to improve the situation is to introduce water reuse systems, which requires a certain percentage of water is expected to return to the water supply. This will replenish stressed water sources as well as provide incentive to ensure wastewater is effectively transported for treatment.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"301 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79726294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
