Nanoparticles, pharmaceutical and personal care products in sewage sludgePravash Chandra Moharana
During the last decade the occurrence of engineered nanoparticles (NPs), pharmaceuticals and personal care products (PPCPs) in the environment have been well documented. Nanoparticles are released from different nanomaterials used in our household and industrial commodities whereas PPCPs are a diverse group of chemicals comprising all human and veterinary drugs, diagnostic agents and cosmetics such as fragrances and sun-screen agents which enter into environment by excretion of humans and domestic animals, disposal of unused or expired PPCPs to drain and ultimately contaminate the sewage sludge and soil. Toxicity of many nanoparticles in wastewater and sludge and their fate to soil are the unanswered question (Brar et al., 2010). The phytotoxicology of nanoparticles (multi-walled carbon nanotube, aluminum, alumina, zinc and zinc oxide) on seed germination and root growth of radish, rape, ryegrass, lettuce, corn, and cucumber are reported by Lin and Xing, 2007 and Oleszczuk et al., 2011. Application of higher doses of ZnO-NPs inhibited the production of methane, respiration and also nitrification during anaerobic digestion of waste activated sludge (Liu et al., 2011; Mu and Chen, 2011). Some of the nanoparticles like Fe3O4, FeS, CeO2, etc. are used for removal of pollutants from wastewater and sludge. The pharmaceuticals like ibuprofen, naproxen, ketoprofen, diclofenac, phenazone, bezifibrate, erythromycin, sulfamethazine, trimethoprim, triclosan, musk compounds, etc. are identified in wastewater and sludge (Daughton and Ternes, 1999). These PPCPs react with other organic molecules to produce Phase I and Phase II compound which are more toxic than parent compounds. Bioremediation by fungus Trametes versicolor is one of the option to reduce pharmaceuticals to toxicity from sewage sludge (Rodríguez-Rodríguez et al., 2011).
Monitoring pharmaceutical residues in sewage treatment plants , water treatment plants,rivers and fresh water lakes rises the concern of it's possible impact on human health and aquatic health.it's persistence in environment create many question about their fate and possible toxicity to human on along term of exposure ,microorganisms and sensitive aquatic species.however it’s concentration isn't critical to create adverse effect on human studies proved some effects on aquatic organisms .multi effort should be done to assess it's risk and create a technique to get rid of it.

Abstract This research paper is focused on the study of various environmental aspects and their impacts arising from the Indian manufacturing industries. Our environment is being polluted day by day due to rapid industrialization. Today the delicate ecosystem of our planet is facing a danger of destruction on a scale as never before in the history of mankind. Forests are diminishing at an alarming rate, landmasses are getting eroded, climate in different parts of the world is undergoing a change due to global warming and clean air and water are increasingly becoming rare commodities. So it is high time to be aware and alert about environmental protection which cannot be done without understanding the environmental aspects. Present study tried to explain the significant environmental aspects arising from Indian manufacturing industries by analyzing the data collected through questionnaire survey. It is observed from collected data that emission to air is most significant environmental aspect in Indian manufacturing industries in respect to severity i.e. the effect of this environmental aspect is more harmful for human beings. Noise environmental aspect is having more efficiency, probability and duration, it means this environmental aspect is produced in each and every manufacturing company and affects the environment. Emission to water is second most important environmental aspect with respect to severity, probability and frequency. The degradation of Land Environmental Aspect effects the environment after the emission to water environmental aspect. But acid deposition, use of hazardous substances and production of toxic waste etc. environmental aspects have moderate significance as they have less probability, less frequency and less duration. So, Manufacturing Industries have to make monitoring plan for all these environmental aspects preferably for emission to air, release to water and noise. Key words: Environmental Aspects, Severity, Duration, Probability and Frequency, Degradation of Land, Hazardous Substances.

Although 76-90% of the BMW is non-hazardous and harmless as any of the other municipal waste, the remaining 10-26% is hazardous to humans or animals and deleterious to environment. Inappropriate handling of the BMW may have serious public health consequences and the significant impact on the environment. Major hospitals contribute substantially to the quantum of generation of the BMW. Smaller hospitals, the nursing homes, clinics, the pathological laboratories and blood banks also have major contribution to BMW. The common methods adopted for the BMW disposal are incineration and land filling. However, these methods are mainly considered more expensive and less ecofriendly due to their main negative impact on the environment

THE IMPLEMENTATION OF ENVIRONMENTAL CRIMINAL LAW ENFORCEMENT TO PREVENT THE G...IAEME Publication
This research aims to examine the Criminal Law Enforcement of mercury accu
disposal by industrial used batteries around residential areas so as to cause
underground water pollution, in order to implement environmental criminal lawen for
cement which is currently still weak in handling cases of environmental pollution
and/or damage in Indonesia. The approach used in the research is Socio-legal
Research, because it does not only use an approach in one legal discipline but uses
several other disciplines such as medicine, chemistry, social sciences, environmental
sciences and so on. Based on the results of research in the field illustrating that the
environmental criminal law enforcement against underground water pollution due to
the disposal of mercury by the used battery smelting industry is open dumping into the
environmental field, waste is thrown away in residential areas so that the
contaminated soil is dangerous well water is not suitable for consumption, the fruit
from the tree is not suitable for consumption and not a few people are attacked by the
disease until the baby is born with disabilities (paralysis and mental retardation). One
of the factors is the weak criminal lawen forcement, especially in the environmental
sector, so that in the implementation of many cases environmental pollution and/or
destruction is not resolved completely. Therefore, it is necessary to take appropriate
steps to optimize the enforcement of environmental criminal law by implementing
environmental criminal law enforcement, especially in handling cases of open
dumping of mercury to realize sustainable development.

Management Considerations
Waste treatment involves three processes that is chemical, physical and biological which are demanding in terms of resources. It is clear from the budget that the treatment process requires finance as well as other considerations so as to run a treatment plan. The biological aspect of treatment is achieved through licensing and chemical waste treatment so as to ensure that no health hazard is posed to the community as well as the surrounding environment.
Physical and chemical treatment of wastes is demanding in terms of workers equipment and the operations to be undertaken for it to be a success. Different processes and operations are carried out so as to process wastes for energy and material recovery. The selection of the unit of operations and systems is dependent on the nature of the wastes. Different wastes are hazardous to the environment and therefore chemical treatment is necessary to reduce the emissions which are normally toxic. Chemical treatment requires highly trained professionals in the chemical fields. Waste treatment process incorporates all levels of qualifications from the low skilled to carry out most of the manual works and the highly skilled to supervise so that the treatment may be a success. A valid license is required from the department of environmental management during the treatment of solid waste. A license is given upon supervision of the site by the agency, if the agency is not satisfied then the activity will be upheld until compliance is achieved. The waste and treatment division also checks the level of hazards so as to give certifications to continue with the process of treatment.
To determine the efficiency of the investment which as discussed requires various resources, return on investment should be considered. The formula to be applied is:
ROI = Net Income (NI) / Investment (I)
NI = Gross Profit – Expenses
I = Stock + Market Outstanding + Claims
ROI = (1,000,000 – 500,000) / (2,000,000 + 5% of 2,000,000)/5
500,000/480,000
= 1.04

Performance evaluation of Effluent Treatment Plant of Dairy IndustryIJERA Editor
Dairy industry is among the most polluting of the food industries in regard to its large water consumption. Dairy
is one of the major industries causing water pollution. Considering the increased milk demand, the dairy
industry in India is expected to grow rapidly and have the waste generation and related environmental problems
are also assumed increased importance. Poorly treated wastewater with high level of pollutants caused by poor
design, operation or treatment systems creates major environmental problems when discharged to the surface
land or water. Various operations in a dairy industry may include pasteurization, cream, cheese, milk powder
etc. Considering the above stated implications an attempt has been made in the present project to evaluate one of
the Effluent Treatment Plant for dairy waste. Samples are collected from three points; Collection tank (CT),
primary clarifier (PC) and Secondary clarifier (SC) to evaluate the performance of Effluent Treatment Plant.
Parameters analyzed for evaluation of performance of Effluent Treatment Plant are pH, TDS, TSS, COD, and
BOD at 200C The pH, TDS, TSS, COD and BOD removal efficiency of Effluent Treatment Plant were 26.14 %,
33.30 %, 93.85 %, 94.19 % and 98.19 % respectively.
Targeting Factors of Ecotax Based on Life Cycle Assessment for Select Criteri...AI Publications
Every drug product, with its apparent patent and trademark from European Patent Commission (EPC), must exhibit its safety utilization starting from its ecological cultivation up to its warranty disposal back to the environment termed as Life Cycle Assessment of drugs. Climate change may be influenced and worsened by several determinants in which pharmaceutical sector may play a big role to environmental pollution and may eventually lead to risks of developing health problems due to environmental toxicities. Therefore, there is a crucial need for remediating drug wastes into renewable energies as corporate responsibility of environmental taxation for the advocacy of Sustainable Development as promoted and regulated by Kyoto Protocol of United Nations Millennium Development Goals of economic prosperity and safety of the public. This paper aims to delineate the waste to energy technology functions for addressing its problems and concerns in carbon tax such as the quantity of renewable power percentage, the amount of greenhouse gases of climate change and its environmental pollutants from waste disposal of expired and used drugs, the prevalence of morbidity and mortality rates in relation to environmental exposure to hazardous substances, and its relative monetary progress and success. Kinetic modelling of equations and its MATLAB simulation code is important for application of waste to energy technology for Sustainable Development. Therefore, delineation of carbon tax in kinetic modelling is quite necessary in resolving issues in economy, society, and environment as exhibited in SELECT criteria mechanism of decision making.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
