Excess Nitrates in Groundwater - Effects and Current Situation in India
Introduction
Groundwater contamination due to excess nitrates is a pressing issue in India, affecting drinking water safety and public health. Nitrate pollution arises mainly from agricultural runoff, improper waste disposal, and industrial activities. However, nitrates are not the only harmful chemicals contaminating groundwater. Other dangerous substances such as arsenic, fluoride, and heavy…

Understanding La Niña: Basics, Causes, and Current Scenarios
What is La Niña?
La Niña, often referred to as the “cold phase” of the El Niño-Southern Oscillation (ENSO) cycle, is a climatic phenomenon characterized by cooler-than-average sea surface temperatures in the central and eastern Pacific Ocean. This powerful natural event significantly influences global weather patterns and triggering a…
River sedimentation is a global concern evidenced by a number of studies conducted. Now, that climate change is being experienced the rapid changes on the river landscape is manifestly observed. As unveiled, natural evolution of landscape and human activities are the two main factors affecting this phenomenon. Different methods of determination of the volume of sediments transported some are employed. Some studies used classic methods utilizing sophisticated apparatus while others artificial intelligence mode of sediment transport prediction.
Palk Bay is an important area for the study of Polychaetes. Already about 16 publications are available on the Polychaetes of Palk Bay. In order to find out the present position a comparative study was made by collecting Polychaete samples from 17 centres having different environmental situations. Out of 41 Polychaetes identified, 16 were found to be new to the study area.

A slurry photocatalytic reactor assessed for the degradation of ciprofloxacin CFX . The effect of operating parameters like initial ciprofloxacin concentration, catalyst dosage and pH on ciprofloxacin degradation was analysed in this study. Batch study was conducted and it showed 90 degradation of the CFX. It was observed the optimum concentration of CFX was 1500 µg l, catalyst dosage was 1 g l at the pH of 9 for the duration of 3 hours. The photocatalytic degradation of CFX followed the pseudo first order kinetics.

Increase in population and urbanization has lead to water depletion and deterioration in water quality. Construction of Sewage Treatment Plants STP based on latest technologies in different parts of the country is necessary to reduce the problem of water pollution. The purpose of STP is to reduce the excessive contaminants from sewage and make the sewage reusable. Sewage treatment helps to reduce the pollution level of the water bodies and reduce the use of water by ensuring that treated water is used for irrigation and flushing toilets. Thus, the efficient working of the STP is utmost important. Anaerobic and aerobic biological processes are commonly used for wastewater treatment. The efficiency of individual units of STP determines the overall performance of the plant and quality of the final treated effluent in accordance with the prescribed governmental standards. This paper presents a critical review on the treatment of sewage by aerobic process and specifically by Activated Sludge Process ASP and its modifications. From the present paper it can be concluded that Sequencing Batch Reactor SBR technology is good in treating sewage.

The fastest growing Industrialization in today’s world of has resulted into degradation of environmental in terms of air pollution. It is not possible physically to achieve a 100 per cent pollution free environment with industries operating. Considering the hazardous effects due to air pollution it is important to make sure that, the least pollution caused by industrial units. To achieve this effective and adequate pollution control techniques are required to implement, so that effects on the environment are minimized. The electrostatic precipitator is one of the major applications of high voltage engineering for air pollution control. It became one of the key control in get rid of harmful particulates coming out and mixing in environment from different industries. Already various research and invetstments in the area of Electro Static Precipitator is growing by looking at the key benefits resulting through the use of it. As numerous projects are in working even at this very moment all over the world, this paper a comprehensive review is attempted to focus on elements of ESP.
