Chapter 1 Introduction
• Water treatment plants produce drinking water for public consumption or "industrial water" for manufacturing or other business operations. Treatment often involves some combinations of: Filtering out sediment and disease-causing organisms. Chemical treatment to remove excess minerals and other contaminants
• Water treatment is any process that makes water more acceptable for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses including being safely returned to the environment. Water treatment removes contaminants or reduces their concentration

Filter onsite generation of wastewater contaminants so that it can be used at the site itself for non-consumptive uses such as for horticulture, washing, cleaning etc.
Preparation of working model for single unit filtration system so that the thoughts can be laid into execution
Able to achieve sustainable environment goals because it should be the very first point kept in mind before beginning any project work.
CHAPTER 4 FILTER MATERIALS AND FILTRATION TECHNOLOGY
4.1 Activated Carbon
Activated carbon is created from a variety of carbon-based materials in a high-temperature process that creates a matrix of millions of microscopic pores and crevices. One pound of activated carbon provides anywhere from 60 to 150 acres of surface area. The pores trap microscopic particles and large organic molecules, while the activated surface areas cling to, or adsorb, small organic

The carbon adsorption process is controlled by the diameter of the pores in the carbon filter and by the diffusion rate of organic molecules through the pores. The rate of adsorption is a function of the molecular weight and the molecular size of the
Both the Benzo(a) pyrene, example of PAH, and Procion Red MX-5B have thin, benzene ring structures and have flat molecules that allow for adsorption. The flat molecules can be adsorbed by zeolites through intercalations. Intercalation is done by Procion Red dye or the PAH getting stuck in between two other molecules of zeolites or charcoal. A difference between them both is that Procion Red dye has OH bond, sodiums, and nitrogens on the structure where the Benzo(a) pyrene doesn’t have any, but doesn’t have that big of an effect of adsorption. Both of these models do the job of adsorption with their similar
More activated copper was added to the filtrate and vacuum filtration was perform again. The error arrived when the filter paper was not replaced because there might have been a hole inside the paper that prevents all the activated carbon to be filter. Since the paper was pitch black, it was impossible to see if there is leakage. The filtrate was less blue after the second filtration. A third vacuum filtration was performed after adding much more activated carbon.
Question # 2: Part C In general carbon diffusion in iron is much “faster” than aluminum diffusion in aluminum.
The process of filtration can be used seeing as the copper particles will be caught by the filter because they are too large to pass through it, while the aluminum chloride particles are small enough to pass through the filter. In order to filter the products, one needs to obtain a funnel, filter paper, and a clean
When concerning our drinking water it should be considered that pathogenic organisms may contaminate soil, as well as stick on to the sediments in the surrounding area; making it more tricky to clear completely. Nitrate poisoning is another large concern,
Julie is typical twenty-five year-old Hispanic woman that grew up in a household where drinking water from the tap was frowned upon. Now, as an adult, Julie drinks about five water bottles per day, which adds up to 150 water bottles a month, or a grand total of 1,800 water bottles per year. Her water bottle of choice – Dasani Purified Water – costs an average of $4.99 per twenty-four pack, or around $0.20 per bottle, at her local Wal-Mart. This means that Julie, by herself, annually consumes around 74 twenty-four packs of bottled water. In other words, she spends $369.26 on drinking bottled water every year1.
Due to the river being connected to many other rivers and lakes, the contaminated water travels downstream and contaminates the water in the other water sources. This is ongoing and makes it harder for the treatment of the water. Propose one possible rehabilitation technique. A rehabilitation technique that could be put in place at this water source would be to enforce harsher penalties for polluting the water and educating the public on the consequences of the pollution.
Another variable of the experiment that was controlled was the time in which the agar cubes spent in the sulphuric acid. The time allowed calculation of the rate of diffusion. The size of the agar cubes was controlled by using a grid and scalpel to, as accurately as possible, cut the agar cubes into the appropriate sizes. The shape of the agar cubes was also controlled. In future, this could be experimented with to investigate how different shaped agar blocks affect surface area to volume ratio and hence the rate of
In this lab we used two processes called Diffusion and Osmosis. Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. Diffusion is a process that requires no energy and involves smaller non-polar molecules. In Figure 1 you can see the molecules spreading throughout the glass from the area of high concentration, so that the areas with low concentration are filled evenly as well. The other process was osmosis.
The New River Basin is located in northeastern North Carolina, although the majority of the basin is actually in Virginia and West Virginia. It is sometimes reffered to as the Kanawha River. It is the fourth smallest basin in North Carolina. It covers 754 square miles and is home to almost 70,500 people. Within in river basin, there are six municipalities and three counties.
The size of the pore matters as well. Diffusion is when the movement of molecules from an area of high concentration to an low area concentration. Osmosis is the movement of water
Disinfection Chemicals Introduction Water disinfection is removal, deactivation or elimination of pathogenic bacteria. Bacteria gets damaged or even deactivated, disabling reproduction. Disinfectants must not just eliminate bacteria. They must have residual effect. The disinfectant must not allow pathogenic bacteria to develop within the domestic plumbing after disinfection, causing water being decontaminated.
ANSWER 1: THE FOUR FOUNDATIONAL PHILOSOPHIES OF BAHRAIN BAY ARE: • SUSTAINABILITY, • QUALITY, • INCLUSIVITY • MODERNITY THE PROJECT IS DESIGNED TO DELIVER THE HIGHEST POSSIBLE QUALITY OF LIFE IN A SUSTAINABLE WAY WITHIN A MODERN CONTEXT. RIGHT FROM ITS INCEPTION, THE PROJECT HAS INCORPORATED VARIED VIEWS FROM DIFFERENT STAKEHOLDERS. THESE PHILOSOPHIES MAY BE USED AS MARKETING TOOLS IN A WAY THAT PROMOTES THE PROJECT
LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
It includes physical, chemical and biological processes to remove the contaminants to produce usable and environmentally safe water. (Wikipedia, n.d.) Also, it is used to be economical and practical in order to pursue the Philippines’ campaign to water conservation. One of the largest consumers of water are malls. It houses a wide scale of stalls, food chains, clothing store, etc.
