Artifi cial wetlands are useful for wastewater treatment; however, relatively little is known of the effects of sewage on artifi cial wetland microbial community structure. Therefore, we assessed the effect of municipal sewage on microbial community diversity in surface water throughout an artifi cial wetland (Xiantao artifi cial wetland) treating municipal sewage. We analyzed the relationship between physicochemical parameters of surface water (i.e., Chemical Oxygen Demand (COD), Total Nitrogen (TN), Total Phosphorus (TP), and
NH4+-N) with microbial community structure (Illumina MiSeq sequencing followed by abundance indices). The results showed that the total microbial community in surface water was signifi cantly correlated with COD, TN, TP, and NH4
+-N (r = 0.764, 0.897, 0.883, 0.839, P < 0.05). In addition, the most abundant taxa were significantly correlated with COD (r = 0.803, P < 0.05). The relative abundance of rare operational taxonomic units in the more purifi ed water farther downstream was higher than in the polluted area, suggesting that rare groups were more sensitive to physicochemical parameters than abundant groups, and that the abundance of some bacteria could indirectly indicate the degree of aquatic pollution. Our results indicate that the responses of microorganisms in artificial wetlands to environmental conditions should be considered to ensure efficient treatment.

DEVELOPMENT OF MATHEMATICAL MODEL TO PREDICT THE TRANSPORT OF E.COLI IN A NAT...IAEME Publication
Development of mathematical model to predict the rate of microbial depositions (E.coli) in a natural pond has been carried out. The models were developed to monitor the rate of concentration at different periods, with respect to the length of the pond at various sample station. Results of the theoretical values were compared with the experimental analysis. The analysis was thoroughly done to determine the physiochemical parameters of the pond. Microbial traces were found from the experimental analysis at different periods up to hundred days. The developed model compared favourably well with the experimental values. The values explain the rate of microbial growth and level of lag phase condition. The growth rate of the microbes were found to be higher because there is high deposition of substrate for growth and energy, while at some periods it degrades showing that the substrates have reduced in concentration including the inhibition from the pH. In some cases when the microbes developed lag phase condition it may be as a result of other environmental factors. Finally, the growth rates are between fifty and hundred days, showing that there is constant regeneration of the microbes including other environmental factors.

Biosystem treatment approach for seaweed processing wastewater Premier Publishers
Wastewater obtained from the seaweed washing process often contains residual chemicals, as the seaweed is typically washed using chemicals. Here, we used a biosystem to treat wastewater obtained after seaweed processing. The research goals were to determine the effectivity and capacity of this biosystem for reducing chemical oxygen demand (COD), biological oxygen demand (BOD), and nitrites in the wastewater. We planted and prepared the biosystem bin, adapted the plants in the biosystem bin until they were ready for use, and we performed wastewater treatment using the biosystem either with or without the addition of an active bacterial suspension. The results show that addition of the active suspension significantly improved effectivity with respect to COD and nitrites (p<0.05). With respect to COD, BOD, and nitrites, the effectivity of the biosystem with an added active suspension was 83.9, 87.2, and 55.5%, respectively; the effectivity of the biosystem without the active suspension was 79.2, 83.3, and 38.7%, respectively. The capacity of the biosystem with an added active suspension was 13.226, 6.805, and 0.014mg/L/m3hour with respect to reducing COD, BOD, and nitrites, respectively; the capacity of the biosystem without an active suspension was 12.485, 6.496, and 0.009 mg/L/m3hour, respectively.
Wastewater recycling is emerging as an integral part of
water demand management. Promoting as it does the preservation of high-quality fresh water supplies as well as potentially reducing the pollutant in the environment and reducing overall costs.
In order to assessing whether algae can reduce the pollution concentration of the effluents by
absorbing the nutrients, it is found that effluents can effectively be treated by employing algal organisisms such
as Oscillatoria and Stigeoclonium species and these organisms are frequently found in the polluted waters and
they were recorded as pollution tolerant forms. In the laboratory procedures out of the several media tested
Modified CHU No. 10 medium was found to be quite suitable for both the test organisms. It was found that up to
87% and 85% of phosphate uptake was achieved by Oscillatoria and Stigeoclonium respectively with 13% and
16% increase of D.O. in the effluents by the tenth day. In case of organic matter Oscillatoria removed 73% and
Stigeoclonium 70% up to tenth day
Standard water quality requirements and management strategies for fish farmin...eSAT Journals
A study on standard water quality requirements and management strategies suitable for fish farming is presented. The water quality criteria studied based on physical, chemical and biological properties of water include temperature, turbidity, total suspended solids (TSS), total dissolved solid (TDS), nitrate- nitrogen, pH, biochemical oxygen demand (BOD) and total hardness. Water samples from Otamiri River in Imo state, Nigeria, were analyzed based on the afore-mentioned criteria to assess its suitability as a source of water for fish farming. The results of the analysis compared with international standards revealed that the river temperature of 26.90C, nitrate-nitrogen value of 0.015 mg/l and total suspended solids of 18.60 mg/l fall within the acceptable range for fish farming. However, the pH of 5.82, total hardness of 5.8 mg/l, total dissolved solids of 13.60 mg/l and biochemical oxygen demand of 0.6 mg/l all differed slightly from the standard recommended values. This study will aid fish farmers on the necessary treatment needed to effectively use water from this source for fish farming.
Keywords: Water quality criteria, Otamiri River, biochemical oxygen demand, total suspended and total dissolved solids.

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.

The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.
