Limbah adalah bahan sisa dari suatu aktivitas atau proses yang sudah tidak memiliki nilai ekonomi lagi (tidak dibutuhkan atau tidak dapat digunakan lagi). Limbah dapat berasal dari aktivitas biologi makhluk hidup, industri perakitan, industri pengolahan suatu bahan, sisa-sisa penggunaan suatu barang, dan lain-lain. Limbah yang dihasilkan dari industri kimia biasanya mengandung senyawa-senyawa berbahaya yang dapat merusak keseimbangan ekosistem perairan. Hal tersebut dikarenakan bahan baku maupun sisa-sisa hasil produksi pada industri kimia tidak dapat diuraikan oleh mikrobiologi dan cenderung bersifat beracun, sehingga diperlukan penanganan khusus untuk bahan-bahan tertentu. Penanganan tersebut dapat berupa pengolahan primer, sekunder maupun tersier. Dalam penelitian ini yang dikaji adalah limbah pewarna tekstil, dimana penanganannya memerlukan pengolahan secara tersier, dengan menggunakan metode Advanced Oxidation Process dengan UV/H2O2.

Tujuan penelitian ini adalah mengkaji kemungkinan pengolahan limbah pewarna tekstil non-biodegradable dengan proses H2O2/UV di dalam bubble column photoreactor, mencari pengaruh kondisi operasi seperti konsentrasi H2O2 dan pH serta waktu tinggal limbah dalam reaktor) terhadap warna, pH, dan BOD/COD dari limbah hasil pengolahan. Manfaat penelitian ini adalah meningkatkan kualitas air buangan dari limbah industri tekstil, memberikan tambahan pengetahuan tentang pengolahan limbah tekstil, memberikan alternatif baru dari pengolahan limbah tekstil .

Penelitian yang dilakukan hanya meliputi percobaan pendahuluan dan percobaan utama yaitu pengolahan limbah dengan 4 variasi konsentrasi H2O2 pada rentang 0,05 – 2 % w/w dan 3 variasi pH, yaitu 3, 8 dan 10. Penelitian ini merupakan penelitian pendahuluan untuk mengetahui model yang tepat untuk kebergantungan laju penguraian limbah terhadap kedua variabel.…...

Waste Water Treatment in India

...Opportunities and Challenges in Waste Water Treatment Market in India India's economy is the eleventh largest in the world by nominal GDP and the fourth largest by purchasing power parity (PPP). Following strong economic reforms from the socialist inspired economy of a post-independence Indian nation, the country began to develop a fastpaced economic growth, as free market principles were initiated in 1990 for international competition and foreign investment. The environment market in India is one that is developing rapidly. Environment-consciousness is gaining ascendancy thereby enhancing demand for hazardous waste management facilities. The ministry of environment and forests has identified 18 highly polluting industry sectors but the most sophisticated technology will have to be imported. There are good prospects for joint-ventures between Indian and foreign companies in this field. In a country famed for its superstitious beliefs and practices, there was no opposition - rather, there was a public welcome - to a clean-up of the Ganges which is considered a Holy River among the majority Hindus. The fact that society acknowledged that their Holy River could be polluted points to a growing understanding of environmental issues in India. And this is good news for foreign and domestic environment-related businesses. In addition to this, there are several products that India needs to import, some of which are storage containers made of, or lined with, waste-handling category......

Roles of Microorgs in Sewage Treatment

...ROLES OF MICROORGS IN SEWAGE TREATMENT Introduction: Many of the microbes present in wastewater are beneficial. In fact, many wastewater treatment technologies are dependent on these beneficial microorganisms for remediation of wastewater so that it won't detrimentally impact the environment. One of the primary goals of biological treatment is the removal of organic material from wastewater so that excessive oxygen consumption won't become a problem when it is released to the environment. (Maier et al, 2009) Another goal of biological treatment is nitrification/denitrification. Nitrification is an aerobic process in which bacteria e.g Nitrosomonas sp, Nitrobacter sp oxidize reduced forms of nitrogen. Denitrification is an anaerobic process by which oxidized forms of nitrogen are reduced to gaseous forms, which can then escape into the atmosphere. This is important because the release of nitrogen to the aquatic environment can also cause eutrophication. (Willey et al, 2008) Another goal of biological treatment is elimination of pathogenic microorganisms either through predation or out-competition. The oxidation/stabilization of organic sludge is also of importance in biological treatment of wastewater. The oxidation of organic materials in the waste water before discharge into the environment can have profound effects on the maintenance of aquatic life and the aesthetic quality of waters. Biochemical oxidation reactions involve the conversion of organic material using...

Waste Water Treatment, St Mary

...St Marys Sewage Treatment Plant and St Mary’s Water Recycling Plant, which located in an industrial area in St Mary’s, a western suburb of Sydney. A group of subject 48350 Environmental and Sanitation Engineering students visited both plants, and observed the operations and maintenance of these wastewater treatment systems. 1.2 St Marys Sewage Treatment Plant In 1939, the Sewage Treatment Plant was first commissioned at St Mary where it serviced a government facility nearby using a trickling filter system – obviously a small scale operation. The Plant was upgraded to a modern primary treatment system in 1964, with subsequent upgrades in 1974 and 1998 to its current tertiary treatment state. The current plant serves an 84 square kilometre region with 138650 people, treating 35 million litres of water per day (St Marys Sewage Treatment Plant, 2010). 1.3 St Marys Water Recycling Plant The Water Recycling Plant is located adjacent to the Sewage Treatment Plant, and was constructed over the period of May 2008 to early 2010, and was operational from September 2010.

Wastewater

...Introduction: This is a preliminary wastewater treatment plant design for Modeltown City with average daily flow rate of 0.500m3/s. For redundancy, the plant is designed with two trains capable of handling the full plant load individually. Bar Rack: The bar rack system should consist of at least two bar racks each capable of handling the plant full peak flow. It should be a self-cleaning system to maximize efficiency and reliability. Grit Chamber: The grit chamber is necessary for the removal of the larger suspended inorganic solids. A vortex grit chamber is recommended for constant energy efficiency over a wide range of flows, small footprint and minimal headloss. Flow Measurement: A parshall flume should be installed after the grit chamber for proper flow measurement of plant influent. For more accuracy a magnetic flow meter can be placed after the parshall flume. Equalization Basin: The wastewater treatment plant being designed requires an equalization basin to even out flow and BOD variations. The average daily flow is 0.500 m3 /s. The following flows and BOD5 have been found to be typical of the average variation over a day. This design includes an aeration system in the equalization basin which can reduce the influent BOD by 10-20%. The volume of the basin will be 9545m3. The mass of BOD5 leaving the tank will be 388kg. Un-equalized BOD Mass Loading Ratios: • Peak to Average 1.97:1 • Minimum to Average 0.140:1 • Peak to Minimum......

Treatment Plan

...that a treatment plan may be formal or it may consist of informal handwritten notes. This is largely dependent on the documentation required by the agency or facility and all the other parties involved. However, regardless of its format, Fritscher (2011) states that the treatment plan should always be subject to change as the case progresses. According to Vrouvas (2013), a treatment plans can work as a mean of providing clients with guidelines that may foster moral support, provide incentive and offer practical solutions for dealing with adversity. This paper will describe a treatment plan and how it will be presented to the client. The paper will also make specific reference to Brittany. Brittany is a 21 year old female who was in foster care until she was 18 and is now employed full-time at a Gentleman's club. She lives in a two-bedroom townhouse and owns a car which is currently uninsured due to her inability to make the payments. The client lives with her unemployed boyfriend. Brittany was recently arrested and subsequently owes a $400 ticket along with all her other bills. She is now considering seeking employment at another gentleman's club on her days off in an effort to allocate enough money to pay her bills. Description of the Treatment Plan A treatment plan will now be described based on the information provided by Fritscher (2011). The description will also be directly linked to scenario five: Brittany. According to Fritscher (2011), a treatment......

Adhd Treatments

...Choosing the Most Effective Treatment for Attention Deficit/Hyperactivity Disorder (ADHD) Sabra Serreyn PSYCH3002 Developing a Psychological Perspective Controversies in Psychology Position Paper Capella University December, 2015 Abstract This paper discusses the most effective treatment for children with Attention Deficit/Hyperactivity Disorder (ADHD). Increasing research has been recommending a combination of both pharmaceutical and psychotherapy treatments. DuPaul and White (2006) state that both the disruptive behavior and genetic aspects need to be addressed, therefore recommending treatment of both medication and behavioral intervention. There has also been a spike in psychiatrists suggesting alternative options in place of medication. Block and Smith (2015) express concern for the side effects of medication and should focus on the behavioral modification aspects. With that being said, the authors do state that medication may help in conjunction with behavioral therapy. Others argue that medication is the answer to resolving symptoms of ADHD because it can repair gray matter in a certain part of the brain. The conclusion comes together stating that all symptoms and treatments need to be taken into consideration in developing a combination therapy strategy. This is the most advantageous and ethical manner of working with a diagnosis.   Choosing the Most Effective Treatment for ADHD Diagnosing children with Attention......

Two River Wastewater Treatment Project

...Running head: Two Rivers Wastewater Treatment Project Wastewater Treatment Project Zoe French Biology 111 Abstract Municipal wastewater treatment plants were suspected to be reservoirs for antibiotic resistant bacteria so a study was conducted. In the study, two samples were collected from a local Wastewater Treatment Plant. The samples were taken at different stages of treatment so one of the samples in the study is untreated, and should contain a greater amount of antibiotic resistant bacteria and the sample that is further along in treatment phase should contain a smaller number of antibiotic resistant samples. The study should demonstrate that, as the wastewater moves through the stages of treatment, less antibiotic resistant bacteria should be detected. The samples should demonstrate that even with treatment, there are still antibiotic resistant bacteria present. Two samples were collected from a local Wastewater Treatment Plant and were taken back to the lab where further study could be done on the types of bacteria that were present. The samples were taken at different stages of treatment. The purpose of this study was to determine what, if any types of antibiotic resistant bacteria were present in the wastewater. The samples taken were processed in the lab, and then agar plated to produce colonies. The colonies were separated using the quadrant streak method to grow individual colonies. These individual colonies were sampled with inoculating needles to......

...Dynamic – The removal of phosphorus from wastewater incorporates the joining of phosphate into TSS and the subsequent departure of those solids. Phosphorus can be joined into either natural solids (e.g., microorganisms) or invention hurries. Tertiary filtration upheld by compound development can decrease signify phosphorus obsessions in the last spouting to low levels. To finish low phosphorus obsessions, chemicals must be added to wastewater to accomplice phosphorus with solids that can then be viably removed through filtration. Aluminum-or iron-based coagulants and polymer are the chemicals most for the most part used consequently. Presentation – Phosphorus and nitrogen are supplements that are vital for maritime plant and green development advancement. Most waters regularly contain enough of these supplements to support neighborhood maritime life. In any case, an abundance of these supplements can over-sustain plant and green development advancement such that they make water quality issues. Common sewage contains phosphorus on a very basic level from human stool and mechanical waste. Phosphorus is a particularly risky constituent since it serves as a basic supplement for green development improvement. Right when the phosphorus availability deals with the advancement solicitations of green development, over the top green development blooms can happen. Exactly when the green development go on, they are consumed in an oxygen asking for procedure, as minuscule life forms......

Water Treatment

... Name: Professor: Course: Date: Water Treatment, Desalination Water is an essential natural resource with a wide range of functions. Water treatment is a process aimed at purifying water for either consumption by human beings and animals or for irrigation. Several processes are applied during water treatment. Desalination is a process of removing salt and other chemicals from sea water. The process is complex with varied economic benefits, environmental and health impacts, and social impact as exemplified by this essay. Desalination involves separation of dissolved salts from brackish, wastewater, wells, industrial feed and sea water. The process of desalination is referred to as reverse osmosis. Water is forced to pass through semi-permeable membrane. Energy is required to enable water passage through the membrane. Reverse Osmosis uses stainless steel pipelines that are extensively iron based. An ancillary equipment is availed in accordance with the chloride concentration in each case. For the low levels of chloride, stainless steel pipe systems are applied. In the case of highly corrosive resistant materials, either super- austenitic materials or duplex stainless steels are used to handle high levels of chloride. Nanofiltration (NF) and Reverse Osmosis are the prevalent membranes driven by pressure. They removes salt and other impurities. The cost of desalination is high because it uses advanced technology that is applied by skilled personnel. It is......

Satellite Scada for Treatment Plants | Isa

...Satellite SCADA for treatment plants | ISA http://www.isa.org/PrinterTemplate.cfm?Section=InTech_Home1&tem... 09 April 2001 by Eric Silverman The technology is available, but is it cost effective? Dedicated, satellite-based business communications using relatively small dish antennas, or very small aperture terminals (VSATs), are no longer only for governments and colossal corporations. An industry study predicted in 1990 that supervisory control and data acquisition (SCADA) services would become a market for VSAT technology by the mid-1990s. VSAT SCADA is now an important tool in the oil, pipeline, and electric utility markets, fulfilling the prediction. VSAT has been successful in these industries, according to Satellite Communications contributor Phil Samuels, because the "electric, gas, and liquid transmission systems transit vast distances, often far from telecommunications and electrical power sources. Monitoring of these transmission facilities and the ability to take action to control their operations are important for inventory, regulatory, and safety reasons." Following its successful entry into these markets, the VSAT industry is now looking for new SCADA applications. One market to attract its interest is water and wastewater treatment, currently about 0.5% of VSAT SCADA installations. A close look suggests VSAT might soon play an important role in water and wastewater plant SCADA. The VSAT SCADA system for a typical water or wastewater treatment......
