Probiotics are good or friendly bacteria that are essential for good health. Probiotic literally means “for life” as opposed to antibiotic meaning “against life.” Probiotics are single-celled lactic bacteria organisms occurring primarily singly or in pairs. Probiotics are live microbial food supplements or components of bacteria, which have been shown to have beneficial effects on human health. The most commonly used probiotic strains belong to genera Lactobacillus sp., Bifidobacterium and Saccharomyces sp. taking into consideration, the above cited facts, and the present study was conducted to isolate and characterise probiotic strains from dairy waste water. Untreated and treated dairy waste water samples were collected from Jaipur dairy in accordance with standard procedures. Morphological and biochemical tests were conducted to identify the strains. The most common and predominant isolate was found to be associated with genera Leuconostoc sp.
益生菌是有益或友好的细菌,对身体健康至关重要。益生菌的字面意思是“生命”,而抗生素的意思是“对抗生命”。益生菌是单细胞乳酸菌生物,主要是单个或成对出现。益生菌是活的微生物食品补充剂或细菌成分,已被证明对人体健康有益。考虑到上述事实,最常用的益生菌菌株属于乳杆菌属、双歧杆菌属和酵母菌属,本研究旨在从乳制品废水中分离和表征益生菌菌株。按照标准程序从斋浦尔奶牛场收集了未经处理和处理过的乳制品废水样本。通过形态学和生化试验对菌株进行鉴定。发现最常见和优势的分离物与Leuconostoc属有关。

In this work the performance of electro coagulation (EC) process was investigated and optimized under different operational conditions for the best removal of wastewater contaminants such as Nitrate, total hardness, Calcium and Magnesium. Samples were obtained from Gaza Wastewater Treatment Plant (GWWTP). Under the optimal condition (pH=7.45, inter-electrode spacing=1 cm, operating time=40 minutes and current density=3.18 mA/cm2), the results showed that the removal efficiency of total hardness, Calcium, Magnesium, Nitrate were 94.6%, 93.3%, 95.2% and 70.9% respectively by using stainless steel electrodes, while for aluminium electrodes the results were 92.83%, 93.33%, 92.30%, 50.43% respectively. For Iron electrodes, the removal efficiencies of contaminants were 87.84%, 88%, 87.64%, 57.26% respectively. In addition, the experimental results also showed that the effluent wastewater was very clear, odourless and its quality is fit for reuse.

As a search for affordable and efficient adsorbents for purification of textile wastewater continues, different natural materials are being investigated. Herein we report the investigation of clay obtained from Lesotho as a low cost and ecofriendly adsorbent for removal of blue textile dye from the stream running through the textile industry populated area in Ha Thetsane about 3 km South West of Maseru – the capital city of Lesotho. Batch adsorption studies were carried out for the effect of mass of adsorbent and particle size, pH, temperature and contact time on the adsorption capacity of the blue dye on the clay. The results show that the smaller the particle size of the adsorbent the higher the efficiency, although the smaller particles could also clog the pores of the filter paper; the adsorption increases under the basic media (pH ≥ 10) and at a low temperature (10-15°C) achieving an extraction efficiency of 88% for a 4 g clay and a 15 mL solution after 15 minutes extraction relative to the original solution. Despite the identity of the dye not being known, the clay adsorbent was found to be quite effective for the removal of this dye. The focus of the future experiments will be to obtain the information from the factories through the relevant government departments about the identity of the dye so that definitive quantitative analysis could be carried out.
随着对经济有效的纺织废水净化吸附剂的研究继续进行,人们正在研究不同的天然材料。在此,我们报告了从莱索托获得的粘土作为一种低成本和环保吸附剂的调查,用于去除来自莱索托首都马塞卢西南约3公里的Ha Thetsane纺织工业聚集区的蓝色纺织染料。研究了吸附剂质量、粒径、pH、温度、接触时间等因素对蓝染料在粘土上吸附量的影响。结果表明:吸附剂粒径越小,吸附效率越高,但粒径越小也会堵塞滤纸的孔隙;在碱性介质(pH≥10)和低温条件下(10-15℃),相对于原溶液,4 g粘土和15 mL溶液在萃取15分钟后的萃取效率为88%。尽管不知道染料的身份,粘土吸附剂被发现是相当有效的去除该染料。未来实验的重点将是通过有关政府部门从工厂获得有关染料身份的信息,以便进行明确的定量分析。

This study aims at evaluating and assessing the impact of domestic and industrial wastes on surface and groundwater quality within the Slaughter area, Trans Amadi industrial layout, Port Harcourt, Nigeria. Standard sampling techniques where adopted. Twenty (20) water samples comprising of ten (10) boreholes and ten (10) surface water samples collected from the study area. Results reveaed slightly acidic water for both the surface and bore water in the area. These parameters were compared with the World Health Organization (WHO) guidelines for drinking water quality. The results from the analyses of the borehole samples yielded parameters that met the requirements by WHO, with exception of Iron (Fe) that had values at some locations above the maximum 0.3 mg/l. This was considered to probably be as a result of corrosion from pipes used in water distribution or dissolution arising from high fabrication activities with in and around the study area. None of the surface water samples met the WHO requirments for drinking water quality. The hydrochemical facies of the water samples were identified by plotting the results of the major cations and anions in milliequivalent per litre in the Piper Trilinear diagram. All the analysed water samples of both the borehole and surface water samples plotted within the Na+ - K+ - Cl- - SO42+ hydrochemical facies, indicating origin from halite dissolution (Saline). The surface water samples were tested against their suitability for irrigation purposes by plotting electrical conductivity which is a measure of the salinity hazard in the use of water for irrigation against Sodium adsorption ratio (SAR) expressed in milliequivalent per litre, in water classification diagram for irrigation. The result yielded high salinity water (C3) - Medium sodium water (S2) and Very high salinity water (C4) - High sodium water (S3) suggesting that adequate care is required in the use of the surface water for the purposes of irrigation. It is therefore recommended that regular water quality monitoring in the area be carried out for proper environmental protection and sustainability.
本研究的目的是评价和评估尼日利亚哈科特港跨阿马迪工业布局斯劳特地区的家庭和工业废物对地表水和地下水质量的影响。采用标准抽样技术。二十(20)个水样,包括从研究区域收集的十(10)个钻孔和十(10)个地表水样品。结果表明,该地区地表水和井底水均呈微酸性。这些参数与世界卫生组织(世卫组织)的饮用水质量准则进行了比较。对钻孔样品的分析结果得出的参数符合世卫组织的要求,但铁(Fe)在某些位置的值高于0.3 mg/l的最大值。据认为,这可能是由于输水管道的腐蚀或研究区域内及其周围的高制造活动造成的溶解。地表水样本均未达到世界卫生组织对饮用水质量的要求。通过在Piper三线性图中绘制以毫当量/升为单位的主要阳离子和阴离子的结果,确定了水样的水化学相。所有分析的钻孔水样和地表水样品均绘制在Na+ - K+ - Cl- - SO42+水化学相内,表明其来源为岩盐溶解(盐)。通过绘制电导率来测试地表水样品是否适合灌溉目的,电导率是灌溉用水对钠吸附比(SAR)的一种度量,在灌溉用水分类图中以每升毫当量表示。结果产生了高盐度水(C3) -中等钠水(S2)和非常高盐度水(C4) -高钠水(S3),这表明在灌溉目的使用地表水时需要足够的小心。因此,建议在该地区定期进行水质监测,以适当保护环境和可持续发展。

Environment protection is a precondition for sustained growth and a better quality of life for all peoples on earth. Aqueous industrial effluents are the main sources of pollution. Among the compounds of these effluents, dyes are particularly resistant to discoloration by conventional methods, and discharges present many problems that must be supported. Synthetic dyes are used in industrials sectors; especially in the textile, industry. There is a certain selectivity of raw cotton fibers for the different types of dyes, depending on the chemical structure of the dyes. We note that this affinity is very high for direct dyes and decreases for reactive dyes and pigment dyes. This study focuses on the elimination of direct dyes wastewater from the textile industry, by their adsorption on waste very adsorbent cotton fibers, the removal rate greater than 75% for the three types of direct dyes used, a mathematical of the adsorption isotherms of and their kinetics of adsorption was made and shows the mathematical models of adsorption curves, it shows that the direct dye red 216 adsorbs very easily and the saturation is obtained after 30 mn and the direct yellow 4 dye s' adsorbs regularly and reaches the saturation 100 mm, which shows that the adsorption is done according to the spatial structure of the dye and the porosity of the cotton this technique is interesting, it allows to recover adsorbate cotton as raw material for several uses and at very low cost.
环境保护是地球上所有人民实现持续增长和提高生活质量的先决条件。含水工业废水是主要的污染源。在这些废水的化合物中,染料通过常规方法特别不易变色,并且排放存在许多必须支持的问题。合成染料用于工业部门;特别是在纺织行业。根据染料的化学结构不同,原棉纤维对不同类型的染料有一定的选择性。我们注意到这种亲和力对直接染料非常高,而对活性染料和色素染料则降低。本研究针对纺织工业废水中直接染料的去除,通过对其在废极吸附性棉纤维上的吸附,去除率大于75%,对所使用的三种直接染料进行了吸附等温线及其吸附动力学的数学计算,并给出了吸附曲线的数学模型。结果表明,直接染料红216极易吸附,30 mn后达到饱和,而直接染料黄4 s吸附规律,100 mm后达到饱和,说明吸附是根据染料的空间结构和棉花的孔隙率进行的,该技术很有趣,它可以回收吸附棉作为原料多种用途,成本很低。

The removal of Al3+, As3+ and SO42- ions from aqueous solution was investigated by using marine fouling. The effect of removal of adsorbent was studied in batch technique under various operating parameters such as pH, contact time, adsorbent dose, adsorbent particle size and metal ions concentration at 500 rpm and 25oC. The maximum removal of Al3+, As3+ and SO42- was 100% at pH 5 for Al3+, pH 8 for As3+ and pH 3 for SO42- using 0.7 g for 120 min. and 45 μm of adsorbent particle size. The Langmuir and Freundlich adsorption isotherm models were under taken to analyse the equilibrium data. Langmuir isotherm showed the best fit to the equilibrium data, which gave maximum adsorption capacity for Al3+, As3+ and SO42- was 28.81, 23.58 and 34.48 mg/g, respectively. The adsorption process follows the pseudo-second-order model. This study recommended that marine fouling can be used for removal of toxic metal ions due to highly efficiently and low cost.
采用海洋污垢法研究了水中Al3+、As3+和SO42-离子的去除。在500rpm、25oC条件下,研究了不同操作参数(pH、接触时间、吸附剂剂量、吸附剂粒径、金属离子浓度)对吸附剂的去除效果。在Al3+的pH为5、As3+的pH为8和SO42-的pH为3时,吸附剂粒径为45 μm,用量为0.7 g,时间为120 min,对Al3+、As3+和SO42-的去除率达到100%。采用Langmuir和Freundlich吸附等温线模型对平衡数据进行了分析。Langmuir等温线最符合平衡数据,对Al3+、As3+和SO42-的最大吸附量分别为28.81、23.58和34.48 mg/g。吸附过程符合准二阶模型。研究结果表明,利用海洋污垢去除有毒金属离子具有高效、低成本的优点。

The available machines used to recycle this waste are very costly. They pack this waste and give them to the local processing plants. So the process of packaging and transporting is much costly. So our intension behind this project is to process the plastic waste as cheap as possible by cutting where it is made for reducing of labour work which results in cost reduction. A cutting machine is designed to reduce large solid material objects into a smaller volume or small pieces. In this project there describes about the experimentation of plastic bottle cutting machine and analysis of mechanism used in machine. Plastic bottle cutter is a machine used for cutting the plastic in small pieces to make waste management easier. We are making this project model for recycling of plastic wastage in domestic area; industries as well as it can be useful to the scrap collectors. This machine is solution on the problem of space.
用于回收这些废物的现有机器非常昂贵。他们把这些垃圾打包,送到当地的加工厂。因此,包装和运输过程的成本很高。因此,我们在这个项目背后的意图是通过削减制造塑料废物的地方来减少劳动力,从而降低成本,从而尽可能便宜地处理塑料废物。切割机的设计目的是将大块的固体物体切成较小的体积或小块。本课题对塑料瓶切割机进行了实验研究,并对切割机的工作机理进行了分析。塑料瓶切割机是一种将塑料切成小块的机器,使废物管理更容易。我们正在制作这个项目模型,用于国内塑料垃圾的回收利用;工业以及它可以对废料收集者有用。这台机器解决了空间问题。
