This document discusses phytorid treatment of wastewater. Phytorid technology uses constructed wetlands with wetland plants to treat wastewater. It was developed by NEERI in India and involves applying wastewater to beds filled with gravel and stones planted with various wetland plants. The mechanism involves biological and chemical processes like microbial activity, sedimentation, and plant uptake that help remove pollutants like BOD, COD, nitrogen and pathogens from wastewater. Some example plants used are elephant grass, yellow flag iris and cattails. Case studies of phytorid plants in India treating municipal and urban wastewater are discussed. The technology is cost effective and eco-friendly compared to

Domestic Wastewater Treatment by Root Zone Technology Option: Colacassia PlantDr. Amarjeet Singh
Root Zone Technology is one of the low cost
methods to treat wastewater. With the help of this system we
can treat the Non-Point sources with best results. To achieve
this goal we have to divide the Non-Point sources into
constructed channels within the river bank followed by root
zone bed or if the Non-Point Sources is coming from natural
nallas we can provide this system within its Channel. We
have prepared channel on which I have developed the root
zone bed and have lab analysis of rector out put on number
of parameters. Flow rate and Detention time are the two
factors on which channels are to be designed. Therefore I
am changing the flow rate and finding out the change in
parameter with respect to detection time. The optimization
is when we get best result with maximum flow. I have got
satisfactory results for the detention time of Three day,
Seven day and twenty one day and Three day. With the help
of this data I have designed the root zone bed system for the
selected actual Domestic Sources.

Treatment of municipal and industrial wastewater by reed bed technology: A lo...IJERA Editor
Reed bed system for wastewater treatment has been proven to be effective and sustainable alternative for conventional wastewater treatment technologies. Use of macrophytes to treat wastewater is also categorized in this method. This new approach is based on natural processes for the removal of different aquatic macrophytes such as floating, submerged and emergent. Macrophytes are assumed to be the main biological components of wetlands. These techniques are reported to be cost effective compared to other methods. Various contaminants like total suspended solids, dissolved solids, electrical conductivity, hardness, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, nitrogen, phosphorous, heavy metals, and other contaminants have been minimized using aquatic microphytes. In this paper, role of these plant species, origin and their occurrence, ecological factors and their efficiency in reduction of different water contaminants have been presented.
Wastewater treatment by vermi filtration technologyvivatechijri
Vermifiltration units are sludge-free, noise-free and low- or no-electricity-requiring systems of
operation. The aim of this study was to emphasize wastewater treatment by vermifiltration technology using
waste-eater earthworms to highlight the benefits of clean and nutritive vermifiltered water (vermiaqua) uses in
agriculture to the farmers. They work on natural capacity of earthworms to treat wastewater from different
sources. In view of rising concern about pollution of water bodies due to discharge of waste in them, it is
necessary to initiate alternative thinking as conventional methods through STPs (Sewage treatment Plants) have
had limited success. In recent years the application of specifically designed filtration based technology
(popularly known as Vermifiltration technology) for treatment of wastewater municipal, urban and agricultural,
is becoming widely acceptable. It treats the wastewater in natural manner without the use of chemicals. In
short, Vermifiltration technology is an improved filtration system for treatment of wastewater. The main
objective of present research work is to provide and popularize a simple, feasible, practically sound, ecofriendly and cost effective technology for wastewater treatment. Vermifiltration technology is such a type of
system, which reduces the impact of sewage and converts into useful water for gardening and irrigation
purpose.

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.

3. INTRODUCTION
Contamination of water by toxic pollutants through the discharge of
municipal, domestic and industrial wastewater has become a worldwide
environmental problem due to its serious consequences on human health,
agricultural crop productivity and aquatic ecosystem.
Phytorid technology has become a logical solution to improve the quality of
contaminated water by acting as a sink for various contaminants.
Phytorid technology was developed by NEERI (National Environmental
Engineering Research Institute) and patented in Indian, European and
Australian countries.
Included in National Environmental Policy.
4. Phytorid technology is a subsurface flow type wherein water is applied to
the beds filled with porous media such as gravel and stones.
The system may include a wide variety of foliage in the form of aquatic,
marsh, ornamental, herbs, grasses and also terrestrial plants known to
grow in water logged condition.
It is a type of constructed wetland system.
It can be used for treatment of domestic, agricultural, slaughter house,
fish pond water.
5. OBJECTIVE
In order to overcome the groundwater pollution by the treated water used in
irrigation field.
To avoid foul, odour and mosquito nuisance.
Facilitates recycle and reuse of water (reuse of grey water up to 95%).
6. CONSTRUCTED WETLAND
Constructed wetlands are artificial wastewater treatment system of shallow
experimental tanks, ponds or channels that are planted with locally available
wetland plants.
They work on natural capacity of plants to treat wastewater from different
sources.
It is used to control or remove hazardous wastes from polluted water under
more controlled environment.
7.
8. COMPONENTS OF CW
Consists of 3 primary components
An impermeable layer (clay) prevents infiltration of wastes down into lower
aquifers.
A gravel layer provides a substrate (i.e an area that provides nutrients and
support) for the root zone. This zone is where water flows and bioremediation
and denitrification take place.
Above ground vegetative layer contains plant material.
10. MECHANISM OF PHYTORID TECHOLOGY
The system have been found to be effective in treating BOD, TSS, N and P as
well as reducing metals, organic pollutants and pathogens.
The mechanism include biological processes such microbial activity and plant
uptake as well as physical-chemical processes such as sedimentation,
absorption at the plant-water interface.
Microbial degradation plays a role in the removal of biodegradable organic
matter in wastewater.
Biodegradation occurs when dissolved organic matter is carried into the
biofilm that attached on plant root systems and surrounding media by
diffusion process. It leads to reduction in BOD and COD.
11. Suspended solids are removed by filtration and gravitational settlement.
Pathogens are removed by sedimentation, filtration and absorption by biomass.
Nitrogen is removed by plant uptake.
12. PLANTS USED
Elephant grass
(Pennisetum purpurem)
Yellow flag iris
(Iris pseudocorous)
Cattails (Typha) Indian shot (Canna indica)
13. ROLE OF PLANT SPECIES
Plants provide huge surface area of attachment and slow down water flows
thus assists in sediment settling and trapping process.
Removal and retention of nutrients and help in preventing eutrophication of
wetlands.
Cattail plant can effectively uptake nutrients.
Macrophytes increase contact time between effluent and plant surface area,
thus increase in the removal of nitrogen.
15. ADVANTAGES
Cost effective.
Less operation and maintenance required.
Minimum electricity requirement.
Facilitates recycle and reuse of water.
No foul odour and no mosquito nuisance.
Works on gravity.
It is eco friendly method for treating sewage.
16. DISADVANTAGES
Time required for treatment of wastewater is more compared to conventional
system.
System is limited by the natural growth rate of plants and length of growing
seasons.
High concentrations of toxic materials could be hazardous to the growth of
plants.
Require a minimum amount of water if they are to survive, they cannot
withstand complete drying.
17. CASE STUDIES : NEERI - PHYTORID
Kalina campus, Mumbai University.
It was the first phytorid treatment
plant developed by NEERI on 5
June, 2006.
Here more than 20 plants are used.
Design to treat the flow of 50 CMD
It used to treat urban waste.
18. Prestigious Projects undertaken by NEERI
Rajyapal Bhavan, Mumbai
Nabi Lake, Lonar
Teen Murthi Bhavan, New Delhi
Smriti Vatika, New Delhi
Nag Nallah, Maharaj Bag Nagpur. This plant has a capacity of 100cu.m/d
19. CONCLUSION
Phytorid system is a promising alternative to treat wastes and an increasingly
recognised pathway to advance treatment capacity of wetland system.
It is low cost, energy efficient, natural and low maintenance systems
compared to the conventional treatment systems.
The treated water has its application in irrigation, flush tanks, river dilution,
gardening etc.
