<p>Pollution has become the enemy of the human, animal and ecosystem. The present environment situation of Bangladesh is not by any means in equilibrium. That why, severe air, water, soil and noise pollutions are frightening our health, ecosystem and economic development of Bangladesh. The underground water of Bangladesh has been polluted due to different heavy metals like Chromium, Arsenic, Lead, Mercury etc. The highlighting of this research work is to analyze different parameters like DO, COD, BOD, TDS, TSS, pH, EC and heavy metals of waste water of different industries before and after treatment. Effluents were collected in the year 2018-2019 during both dry and wet seasons from different industries. So, six industries in Chittagong have been selected to collect the waste water samples for laboratory analysis of different physiochemical quality parameters. Effluents were analyzed during both dry and wet seasons for Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Dissolved Oxygen (DO), pH, Turbidity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Total Solids (TS), Arsenic, Lead, Chromium, and Electrical Conductivity (EC) etc. From the results of this research it was seen that most of the ETP treated water are not within the limits of Industrial Effluent Quality Standards of Bangladesh.</p>Md.

https://www.matjournals.in/index.php/JoEES/article/view/3822
<p>An effort has been put in this work to identify the effects of ozonation processes for decolourization and/or degradation of organic pollutants for environmental protection. In dyes, since the chromosphere collections through conjugated dual bonds, that are answerable for shade, can be wrecked by ozone either directly or indirectly developing short particles, thereby reducing the colour of the effluents. Characteristics of treated effluent were analysed using spectrophotometer and standard COD method. Colour removal of effluent was achieved in 30mins of contact time for Basic brown4 dye at an ozone consumption of 6mg/lit. The effects of dye concentration, pH, and ozone flow rate on ozonation of basic brown4 were studied. The kinetics on ozonation of basic brown4 has been studied.</p>KUMARAVEL AMuthuklumar K.

https://www.matjournals.in/index.php/JoEES/article/view/3936
<p>Access to clean water is the significant need in all nations on the planet in which a great many people and living life forms pass on because of tainted water-related ailments consistently. Various consequences have reported the direct and indirect toxic effects of alum in the form of allergies, tumours and cancers. To exchange alum as coagulants, the mixture of pomegranate peel and banana peel used as coagulants in liquid treatment via coagulation-flocculation procedures were examined. pH and coagulants amount were identified for the mixtures of banana peel with pomegranate peel. The investigation conducted found that pomegranate peel can be a good coagulant which can absorb Biological Oxygen Demand and Chemical Oxygen Demand. The Dehydration method is found to be more efficient for both pomegranate and banana peels. The most elevated turbidity evacuation rate could be accomplished at arrangement pH of 5-9, 4ml/250ml of bio-flocculant to turbid water measurements. In order to minimize dependency on conventional chemical coagulant, various proportion of banana peels and pomegranate peel (bio-flocculant) to alum was used to achieve the best turbidity removal percentage. For river water and pond water turbidity removal efficiency is 86.32% and 90% using natural coagulant.</p>Dr. R. MOHANA

https://www.matjournals.in/index.php/JoEES/article/view/4094
For every day and wholesome dwelling a conductive surroundings is required by means of all residing beings, which include human beings, farm animals, plants, micro-organisms and the flora and fauna. The negative unpolluted environment has a specific composition. One of the biggest threats to environment is pollution which includes water pollution, air pollution, noise pollution, land pollution etc. Water pollution is an alteration in bodily, chemical, organic function of water making it incorrect for its utilization in its natural kingdom. Although in very low concentration water pollution may be neglected but it may prove fatal in extreme cases. It has an adverse effect like death of aquatic life, disruption of food chains, diseases to humans feeding on same water, destruction of ecosystem, eutrophication etc. Release of pollutants from various sources like domestic, agricultural and industrial sectors has dramatically modified the quality of water which contains several harmful residual substances like detergents, oils, colors, dyes, various salts, fertilizers, pesticides ,effluents released from industries release toxic chemicals like heavy metals, chemicals (organic or synthetic) to the aquatic ecosystems. The best solution to water pollution is to reduce it at its source. Separation of pollutants at source is the best method to control water pollution. This comprises physical, biological and chemical split-up to convert the polluted water to clean and usable forms before release. This study exposes an innovative and inexpensive methodology of cleaning waste water from household and industrial sources by employing one of the most under-utilized agricultural by- product i.e. by using corn cobs. In this study we have utilized corncobs to treat domestic wastewater to reduce Calcium and Magnesium hardness, pH, color dye and detergent content and we got positive outcomes. We have also found this method to be cheap and effective.ZEESHAN ADIB AHMEDSufiyan Adib Ahmed

https://www.matjournals.in/index.php/JoEES/article/view/4114
<p>This paper presents a trend analysis of monthly precipitation, mean temperature, maximum temperature and minimum temperature over a period between 1901-2016 (116 years). Non-parametric statistical tests called Mann–Kendall test (MK test) has been used for the analysis. The analysis of temperature trends revealed a significant increase during winter and spring seasons; whereas, there is a decreasing trend in temperature of the monsoon season. Analysis of Precipitation showed a decreasing trend in the months of spring from mid-February to march. Also, snowfall trend over the last 35 years showed a fall of -1.3%. The analyses indicated some evidences of impact of climate change in Shimla, Himachal Pradesh (India).</p>Siby JohnKomal Sharma
