Metering and Analysis of Industrial Waste Waterusing Cloud Computing
This paper deals about analysis of waste water affluent from Industries in an economical way. Industrial wastes generated through various industrial operations are of different chemical composition and complex to decompose. These wastes upon discharge, affect the normal life of a river stream or normal functioning of sewerage and sewage treatment plants, unless pre-treated at the source point itself. The waste water from industries have high proportion of suspended solids, dissolved organic and inorganic solids, COD, BOD, alkalinity or acidityalkalinity or acidity (pH levels), more temperature level. Their different constituents may not be in same proportion as they exist in a normal domestic sewage. This industrial waste water cannot always be treated easily by the normal methods used for treating domestic waste and certain specially designed methods or sequence of methods may be necessary. The detail study of effluents before discharge is necessary to reduce pollution and hence this paper is proposed. Metering also has been proposed to penalize industries if the waste content is beyond threshold levels. As a Case Study the analysis and metering of water is been carried out randomly by collecting water samples of Bellandur lake, the most popular lake in Bengaluru, at different time using sensors and storing the measured values in a cloud (AWS-Amazon cloud Server) via GPRS for further use by the Government.

Web based Water Turbidity Monitoring and Automated Filtration System: IoT App...
Water supplied to residential areas is prone to contaminants due to pipe residues and silt, and therefore resulted in cloudiness, unfavorable taste, and odor in water. Turbidity, a measure of water cloudiness, is one of the important factors for assessing water quality. This paper proposes a low-cost turbidity system based on a light detection unit to measure the cloudiness in water. The automated system uses Intel Galileo 2 as the microprocessor and a server for a web-based monitoring system. The turbidity detection unit consists of a Light Dependent Resistor (LDR) and a Light Emitting Diode (LED) inside a polyvinyl chloride (PVC) pipe. Turbidity readings were recorded for two different positionings; 90° and 180° between the detector (LDR) and the incident light (LED). Once the turbidity level reached a threshold level, the system will trigger the filtration process to clean the water. The voltage output captured from the designed system versus total suspended solid (TSS) in sample water is graphed and analyzed in two different conditions; in total darkness and in the present of ambient light. This paper also discusses and compares the results from the above-mentioned conditions when the system is submerged in still and flowing water. It was found that the trends of the plotted graph decline when the total suspended solid increased for both 90° and 180° detector turbidimeter in all conditions which imitate the trends of a commercial turbidimeter. By taking the consideration of the above findings, the design can be recommended for a low-cost real-time web-based monitoring system of the water quality in an IOT environment.

TOC Workshop-1
Our objective is to demonstrate how Total Organic Carbon (TOC) analysis is a quick, accurate screening alternative for critiquing cleaning validation samples.
Typical laboratory testing includes the development and implementation of analytical methods that test for residues of previously manufactured products, cleaning detergents, chemicals, solvents, byproducts, degradants, and microbial contaminates (from wet environments after the cleaning validation). TOC analysis has become one of a series of analytical methods used to assess the effectiveness of a cleaning validation. Almost any residual compound can be detected if three non-specific analytical (screening) tests are applied to a cleaning validation: TOC (for organics characteristics– carbon), pH (for acid/base characteristics) and conductivity (for ionic characteristics).
Analytical precision and analyte recovery for cleaning agents (detergents) and other possible contaminates that may be found in clean in place (CIP) solutions will be investigated for TOC. TOC analysis demonstrated equivalent or better correlation to cleaning validation compounds in comparison to traditional analytical methods. Some qualities that make TOC a viable part of a cleaning validation includes: high sensitivity, high recovery of samples, non-specific measurement, ease of use (little method development), minimal interferences and cost effectiveness.
This presentation will focus on the characteristics and benefits of TOC with general implementation guidelines for performing cleaning validation. By taking a proactive approach to one’s cleaning validation program, one can guarantee effective performance while minimizing downtime.

Introduction
Access to clean drinking water in underdeveloped areas of the world is a growing problem due to global increases in both population and pollution. Current methods of water treatment are impractical to apply in many parts of the world, as these technologies are expensive, require large facilities staffed by a litany of professionals, and the production/disposal of treatment chemicals that often have negative environmental impacts. The need to develop a method of water treatment that is less expensive, operates without the use of chemical treatments, and has relatively low electrical power usage is of profound importance. One of the most viable and promising optionsoptions is to make use both cavitation and ultraviolet light (UV). The purpose of this project is to develop a system for researching the combined effects of these two forms of water purification.
Cavitation occurs when the static pressure of water drops below vapor pressure. Small microbubbles form and slowly collapse in an energetic manner. As cavitation bubbles collapse, temperatures within the bubble can reach upwards of 5000 degrees Kelvin. Due to pyrolytic decomposition that takes place within the collapsing bubbles, the OH radicals and shock waves arecan be generated at the gas–liquid interface (A. Agarwal et al, 2011). These radicals degrade contaminants suspended within the water that would otherwise resist ultraviolet degradation. This makes cavitation a promising method of water treatment.
Ultra violet light is capable of killing bacteria and living contaminants in water. Short wavelength UV light, in the range of 10 nm to 400 nm, kills cells by interacting with their structures and disrupting DNA (NIOSH, 2008). UV light is capable of killing up to 99.99% of bacteria in clear water. This system of water purification is both cost effective and nontoxicchemical free but it cannot break down particle contaminants that bacteria tend to live in. However in combination with a particle filtration system, or in our case a cavitation system, UV reactors are simple to maintain, cost effective and chemical free.
The concise purpose of this team’s senior design project will be to develop a fluid flow test apparatus to demonstrate the degree of effectiveness of the combination of UV radi.

Water treatment is crucial for safe consumption and usage. It removes contaminants like chlorine, fluoride, parasites and dioxins that can be hazardous to health. For haemodialysis patients who use large volumes of water, treatment is essential to avoid health complications. Reverse osmosis is commonly used as it removes bacteria, endotoxins and dissolved solids. Strict water quality monitoring and disinfection is needed, as contaminated water could be life threatening for haemodialysis patients. Proper equipment, storage and process design are important to ensure safe, effective water treatment.
Bs water-treatment-presentation-1-1 finals
Water treatment is important for haemodialysis patients who are exposed to large volumes of water directly through their bloodstream. Reverse osmosis (RO) is commonly used to treat water for haemodialysis as it removes contaminants, bacteria and endotoxins. Proper design, monitoring and maintenance of the RO system is required. Storage tanks must be designed to prevent bacterial growth and reject water can be recycled to reduce wastage. Regular testing is needed to ensure water quality meets Association for the Advancement of Medical Instrumentation standards to protect patient safety.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
