DENITRIFICATION OF CONTAMINATED WATER INTRODUCTION:- This is an eco-friendly and economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria

How to survive an earthquake The ground starts to shake‚ debris are falling everywhere around you‚ pictures‚ vases‚ mirrors‚ the family pet. What do you do in a situation like this? Turn and run or do you get down and hide? Most people would pick the first option‚ but that is one of the most dangerous things you can do in an earthquake. The best way to get through a natural disaster like this is to take cover‚ have an emergency household survival kit‚ and stay in contact. First of all‚ before

2013/2014 Assignment 1 (10 marks) Answer ALL the questions. 1. Discuss briefly fluid mosaic model for membrane structure. (6 marks) Answer: The lipids and most of the protein in the plasma membrane are free to bob about‚ sliding from one location in the membrane to another. Because lipids and proteins move about laterally within the membrane‚ the membrane is a fluid mosaic of lipids and proteins. The membrane fluid is since the composition of any location on the membrane can change. In the same manner

Effects of Water Pollution Image source: NASA Water covers 70% of the Earth’s surface and makes up over 60% of the human body. Water pollution affects marine ecosystems‚ wildlife health‚ and human well-being. The answer to solving pollution is to make changes in our daily habits and pay more attention to the types of products we consume. The following lists display causes of water pollution and the effects it has on human health and the natural environment. Causes of Water Pollution

super-heating dried coconut husks in a low oxygen environment‚ using a process called pyrolysis. The resulting "biochar" husk‚ is a purified form of carbon‚ containinglarge amounts of cellular sized surface area‚ negatively charged to attract positively charged toxins. Toxins in the water become attached to the husk’s carbon surfaces.Over time‚ the attractive charge of carbon surfaces are neutralized‚ making it time to change the filter. There are many types of carbon water filters that can be easy to install

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker
