INTRODUCTION This Preliminary Close-out Report (PCOR) documents that the construction activities for the Avtex Fibers Superfund Site (Site) have been completed. This determination was conducted in compliance with the Close-out Procedures for National Priorities List Sites (OSWER Directive 9320.2-22, May 2011). The U.S. Environmental Protection Agency (EPA) and the Commonwealth ofVirginia conducted a pre-final inspection on July 1, 2014 and determined that the potentially responsible pru.ty (PRP) constructed the remedy in accordance with approved design plans and specifications. No additional construction activities are anticipated. The PRPs have initiated activities necessary to achieve performance standards and site completion. II. SUMMARY OF SITE CONDITIONS Background The A vtex Fibers Superfund Site is a former rayon manufacturing facility consisting of approximately 440 acres, located in Front Royal, Virginia. The Norfolk Southern railroad runs through the middle of the Site separating the former production facilities on the eastern side of the railroad tracks from the disposal units located on the western side of the railroad tracks. Residential areas are located to the east, south and north of the property boundaries. The South Fork Shenandoah River is located along the western portion of the property. The location of the Site is shown on Figure 1. A photo of the Site taken in May 2014 from an overlook in Skyline Drive in Shenandoah Park is provided in Appendix 1. The Site was proposed for the National Priorities List (NPL) on October 15, 1984 (49 FR 40320) and listed on the NPL on June 10, 1986 (51 -FR 21 054) due to the discovery of groundwater contamination in residential wells, and the first ROD, selecting a "pump and treat" remedy for groundwater, was issued in September 1988.

Wastewater Treatment and Its Process Dr
Wastewater Treatment and Its Process Dr. Sai Bhavani Sevella¹, Saileja Sevella² 1Assistant Professor, Department of Environmental science, Nizam College, Osmania University, Hyderabad, Telangana, India. 2Assistant Professor, Department of Business Management, University College for women, Koti, Hyderabad, Telangana, India. Abstract: Waste water is the used water, wastewater treatment as water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the Environment. Nature has an amazing ability to cope with small amounts of water wastes and pollution, but it would be overwhelmed if we didn't treat the billions of gallons of wastewater and sewage produced every day before releasing it back to the environment. Water treatment plants reduce pollutants in wastewater to a level nature can handle. In this paper, the focus is on wastewater treatment and process of treating sewage water. Keywords: Environment, Pollutants, Treatment plants, Wastewater. 1 Introduction Wastewater (or waste water) is any water that has been contaminated by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or storm water, and any sewer inflow or sewer infiltration". Therefore, wastewater is a by product of domestic, industrial, commercial or agricultural activities. The characteristics of wastewater vary depending on the source. Types of wastewater include: domestic wastewater from households, municipal wastewater from communities (also called sewage) and industrial wastewater. Wastewater can contain physical, chemical and biological pollutants. Households may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers.

The Usage of Domestic Water Filtration Systems in Malaysia
CORE Metadata, citation and similar papers at core.ac.uk Provided by University of Southern Queensland ePrints University of Southern Queensland Faculty of Engineering and Surveying The Usage of Domestic Water Filtration Systems in Malaysia A dissertation submitted by LAW BEE BEE In fulfillment of the requirements of Courses ENG4111 and 4112 Research Project towards the degree of Bachelor of Civil Engineering Submitted: October, 2005 ABSTRACT Water is closely related to human health as there is about 70% of water found in human bodies. In the recent years, consumers are concern about the quality of tap water due to the water pollution issues published in the mass media. Manufacturers and distributors of domestic water treatment systems took this opportunity to promote their own water filtration systems. Different types of domestic water treatment systems have been introduced to the public. In this research project, six types of domestic treatment methods were identified, namely activated carbon filter, membrane filter, reverse osmosis system, distillation system, ultraviolet light system and combination unit. The theories and technologies involved in each type of water treatment system are being studied. From the literature review, the mechanisms involved are convincing and almost ideal. In order to investigate the effectiveness of each water treatment system, laboratory experiments have been conducted to justify the reported results. The laboratory experiments take into account parameters such as apparent colour, turbidity, total free chlorine, total aluminium, total iron and total chromium. Three samples of each treatment method are collected in order to obtain the average value. The percentage removal of each parameter is obtained by taking readings before and after treatment.

A Study of the Fluid Dynamics Involved in Water Purification
Project Number: MQP 4501_MQF_B11 A STUDY OF THE FLUID DYNAMICS INVOLVED IN WATER PURIFICATION METHODS WITH REVERSE-OSMOSIS by Shane Bellingham, Robert Flaherty, Daniel Metcalf, Alex Pittera, Jose Sosa, and Garret Yablonski A Major Qualifying Project Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science in Mechanical Engineering ______________________ _______________________ _____________________ Shane Bellingham Robert Flaherty Daniel Metcalf ______________________ _______________________ _____________________ Alex Pittera Jose Sosa Garret Yablonski APPROVED: DECEMBER 2011 _______________________________ Professor M.S. Fofana, Major Advisor Mechanical Engineering Department ABSTRACT The purpose of the report is to analyze the most promising methods for distilling pure water from otherwise unusable water: reverse osmosis with several stages of preprocessing. By forcing the intake water through a fine membrane the system removes the need for heat, hence combustion, to be used to purify the water. High pressures in the filtration process allow a person to utilize salt water, which comprises almost all of the available water on the planet, and also waste water to create a distillate which is safely consumable by a human and for use in electronic cooling systems. Eliminating fuel consumption in the system decreases cost significantly and creates an environmentally friendly system out of a process usually responsible for the release of large quantities of greenhouse gases. Preprocessing allows even the most polluted waters to safely be passed through the membranes without the destruction normally caused by chemical pollutants found in many freshwater areas. To increase the efficiency of the system, the fluid dynamics through the pipes and pump were analyzed to search for areas of weakness in the design.

International Journal of Advanced Science and Technology Vol. 29, No. 7, (2020), pp. 12130 - 12137 Treatment of Sand Filter Backwash Water from Water Treatment Plant Ashutosh Diwakar1, Ahire Rituja2, Gosavi Shubhangi3, Ahire Suvarna4, Yakub Ansari5 1,2,3,4UG Scholar in Department of Civil Engg. MMANTC, Mansoora, Malegaon(Nashik), India 5Assistant Professor in Department of Civil Engg. MMANTC, Mansoora, Malegaon(Nashik), India Abstract In this study several tests were conducted to investigate the possibility of re-use the filter backwash water. Backwashing is done to prevent sand-granular-gravel filter media from clogging due to increased passage of particles and microorganism. Which results in wastage of water, it is a very common problem in WTP. The amount of wash water generated estimated at a rate of (10-15%) of the amount of purified water in the plant. Sand filter backwash water (SFBW) and sludge water are generated in most of drinking WTP. Good quality of water can be obtained by recycling of SFBW by adopting proper treatment. Experiments were conducted on Raw Water (RW) and SFBW samples from Surface WTP. Reuse of SFBW is of great interest. Jar test was performed with other parameters such as turbidity, color, odor and total suspended solids were recorded for RW, SFBW and found significant differences. Results indicated that in quality of RW and SFBW can be achieved with proper treatment. Keywords: SFBW, RW, Filtration, Reuse, Pre-Treatment, Water, Activated Charcoal 1. Introduction Actually, only 1% of the world's water is usable to us. About 97% is salty sea water, and 2% is frozen in glaciers and polar ice caps.

Design and Fabrication of Hand Pump Operated Water Purification
IJIRST –International Journal for Innovative Research in Science & Technology| Volume 1 | Issue 11 | April 2015 ISSN (online): 2349-6010 Design and Fabrication of Hand Pump Operated Water Purification System using Reverse Osmosis Nikhil Jacob Zachariah Vimal P Sunil Department of Mechanical Engineering Department of Mechanical Engineering Saintgits College of Engineering Saintgits College of Engineering Sachin Tomy Vijith K Department of Mechanical Engineering Department of Mechanical Engineering Saintgits College of Engineering Saintgits College of Engineering Abstract Drinking water is a necessity to which millions of people throughout the world have limited access. Water is often seen as the most basic and accessible element of life, and seemingly the most plentiful. More than a billion people lack access to drinking Water. Simply providing access to clean Water could save two million lives each year. As the population grows, the freshwater available to each resident dwindles. Water purification is the removal of contaminants from untreated water to produce drinking water that is pure enough for human consumption. Substances that are removed during the process include parasites, bacteria, algae, viruses, fungi, minerals (including toxic metals such as lead, copper and arsenic), and man-made chemical pollutants. In this paper, an apparatus and methods for producing purified drinking water are disclosed. A hand pump is used in a closed system to generate pressure to pass the water through a series of filters and a reverse osmosis membrane to obtain potable water at the outlet. The flow obtained was analysed using ANSYS and the system delivering highest output was chosen. The project facilitates the availability of pure drinking water without using any electrical components or devices.

Removing Pharmaceuticals from Water Doesn't Come Cheap Or Easy
1/24/2019 Removing Pharmaceuticals From Water Doesn't Come Cheap Or Easy FOUNTAIN VALLEY, Calif. — Shivaji Deshmukh drinks water extracted from raw sewage. He knows the water is clean because his job is to help make it so as an engineer at the Orange County Water District. “It’s an efficient, cheap water supply — and it’s the best quality,” says Deshmukh, amid the hiss of machines at the state-of-the-art facility. Performing the recycling transformation requires a battery of treatments. Wastewater strained and disinfected at an adjacent sewage treatment plant is first filtered through tiny straws. Then, in a process called reverse osmosis, the water is forced across a spiraled sheet of plastic with holes so small that little else can slip through. In the final phase, the water is zapped with ultraviolet light. The three-step operation is one of the most sophisticated cleansing systems anywhere. While the incoming water contains minuscule levels of prescription drugs, tests for any traces of a half-dozen pharmaceuticals, conducted as the treated water leaves the plant, detect nothing. The end product supplies more than 500,000 Orange County residents for a year, nearly one-quarter of the district’s potable water needs. The cleansing procedure illustrates how difficult — and expensive — it is to scrub virtually every iota of contaminant from our supplies. The standard ways of cleaning water are not designed to snare the tiny amounts of prescription drugs that survive digestion, and then, with a flush of the toilet, begin their journey toward America’s taps. It’s not an academic exercise: According to an Associated Press investigation, scientists have found that water piped to tens of millions of people nationwide contains minute concentrations of dozens of pharmaceuticals from tranquilizers to painkillers to antibiotics.

Waste Water Treatment: an Overview
EDITORIAL NOTE Waste water treatment: An overview Bajpai EDITORIAL Wastewater treatment is a process used to remove contaminants from sludge in a wastewater treatment plant. Disposal options for dried solids vary wastewater or sewage and convert it into an effluent that can be returned with the type and concentration of impurities removed from water. to the water cycle with acceptable impact on the environment, or reused Solids such as stones, grit, and sand may be removed from wastewater by for various purposes (called water reclamation). The treatment process gravity when density differences are sufficient to overcome dispersion by takes place in a wastewater treatment plant (WWTP), also referred to as a turbulence. This is typically achieved using a grit channel designed to produce Water Resource Recovery Facility (WRRF) or a Sewage Treatment Plant an optimum flow rate that allows grit to settle and other less-dense solids to be (STP) in the case of domestic wastewater. Pollutants in wastewater are carried forward to the next treatment stage. Gravity separation of solids is the removed, converted or broken down during the treatment process. primary treatment of sewage, where the unit process is called "primary settling The treatment of wastewater is part of the overarching field of sanitation. tanks" or "primary sedimentation tanks." It is also widely used for the treatment Sanitation also includes the management of human waste and solid waste of other types of wastewater. Solids that are denser than water will accumulate as well as stormwater (drainage) management. The main by-product from at the bottom of quiescent settling basins.
