It is very effectively in removing or eliminating the heavy metals that dissolved in the waste stream. The solubility of the heavy metal can be decreased by properly adjusting the pH value. For examples, lime is commonly used to the precipitate the metals ion into insoluble metal
It also decreases the amount of sludge, which needs to be disposed. Electrocoagulation is a technology that removes components from wastewater by applying a strong electric field that produces a series of oxidation and reduction reactions. By decomposing the electrodes, the metallic ions produced are subject to fast hydrolysis and the products of the hydrolysis neutralize the charge of the suspended particles driving them to a fast coagulation and sedimentation. Electrodes consist of iron and aluminium have special coagulation properties and are very efficient in decolouring industrial wastewater. In recent years, the EC has been successfully tested to decolourization of dye-containing solutions.
Add the food that we consume and the polluted air that we inhale and we have created a whole lot of acidic waste in our body. Alkaline water helps neutralize acids and also removes toxins from our body. With a pH range of 7.2 to 9, alkaline water is completely safe and helps improve our blood function. When there is extra acid in our body, our immune system weakens. This, in turn, can cause many diseases.
The water is securely transported to wherever it is needed The techniques and the technology used to remove impurities from waste and supply water have greatly evolved. They have increased in efficiency, precision, and some are less environmentally endangering, but they have also increased in scale and in cost. It is concerning that the need of purification has increased on a large scale, but it is a concept which has been present for centuries and one which is vitally important to our society. If waste and supply water are not properly transported and treated there would be many consequences such as disease outbreaks, harmful pollution, poisoning, etc… Thus it is important that each town or city has a good sewage and/or pipe system as well as a functioning waste and supply water treatment plant.
• As a result of a large population of people in highly urbanized areas, the pressure to keep a continuous flow of water increases In this peer-reviewed article it discuses water recycling in urban areas and it studies different design models and it studies how and which of the three are most efficient in terms of water quality and energy used. In these three models they use different methods such as a satellite water reclamation facility, etc. to look at potential for water reuse.
From all of the parameters that were examined, turbidity is a characteristic related to the concentration of suspended solid particles in water and has been adopted as an easy and reasonably accurate measure of overall water quality. Turbidity can be used to measure the performance of individual treatment processes as well as the performance of an overall water treatment system. 2.2 Conventional Method In this study, the conventional method of water treatment plant was focused. The treatment processes of raw water before it can be used for public consumption must be based on removal level of impurities to comply with various guidelines. The extent of treatment depends upon the quality of the raw water and the desired quality of treated water (Hong, 2006).
CHAPTER: 1 INTRODUCTION 1.1 Introduction[1.5] As the use of water is increasing day by day, there is growth in demand for new water treatment technologies as the world’s population increased and fresh water sources are polluted. Therefore its need to find out an alternative method to purify the waste water for recycled or reuse to fulfil the demand of the world. Electrocoagulation is one of the best process for purifying water and waste water from different resources. Waste water treatment technologies used in both municipal and industrial applications have to be further developed in order to reduce the pollution of receiving water bodies. In the last decade, this technology has been increasingly used in the United States and then after many countries started to use

The last section of the external environment analysis is a reflection of industry opportunities and threats. The opportunities for Novartis in the pharmaceutical industry include things such providing more services for the poor and third world countries, using core business capabilities and resources the create long-term growth, adapting to changes in diseases and health care issues, and utilizing technology innovations to drastically improve core aspects of the business. The threats to Novartis within the industry include competition from rivaling companies, changing laws and requirements, rapid changes in technology, increasing competition over low priced generics, and shifts in tastes to lower cost alternatives.
Sewage discharge is a major component of water pollution, contributing to oxygen demand and nutrient loading of the water bodies, promoting toxic algal blooms and leading to a destabilized aquatic ecosystem. This problem is compounded in areas where wastewater treatment systems are simple and not efficient. The establishments of oxidation ponds are popular for sewage treatment methods for small communities because of their low construction and operating costs. In this study, oxidation pond having the capacity of treating standard A sewage influent have been analyzed to better understand the efficiency of the sewage oxidation pond. The effluent standard has already been implemented by INDAH WATER KONSORTIUM.
Hydrogeologists and water resource managers have realized that the increased demand for drinking water, due to population growth, has placed a huge burden on our nation's groundwater resources. Groundwater resources make up a minute 0.31% of the world's water supply. Groundwater quality can be defined in terms of the concentration of its chemical constituents relative to a variety of potential uses. Groundwater is used not only for drinking water, but also for irrigation, industrial supply and cleaning. For groundwater to be used as a supply, it must be situated in an aquifer.
