This document summarizes a study on using a reed bed system to treat sewage wastewater. Reed bed systems are a low-cost alternative to conventional wastewater treatment. The study constructed a model reed bed system using plastic containers layered with gravel, sand, soil and planted with reeds. Wastewater samples from a local sewage drain were treated in the model system for 5, 10, 15 and 20 days. Testing showed the reed bed system reduced levels of pH, odor, color, conductivity, alkalinity, COD and BOD over time, with higher removal rates at longer detention periods. The reed bed system proved an efficient and low-cost method for wastewater treatment
DOMESTIC WASTE WATER TREATMENT BY FLY AND WOOD ASH ALONG WITH ADDITIVES MATER...IAEME Publication
Fly ash and wood has been separately studied for their adsorption properties. A lot of work has been reported on the adsorption and other construction related uses of fly ash. But a little or no work so far has been reported for the use of fly ash for the treatment of domestic laundry waste water. The present study reports the use of fly ash alone and in combined state in different ratios with wood ash for the treatment of domestic laundry waste water. Effect of various parameters such as combination ratio of fly ash and wood ash, contact time, adsorbent dosage and particle size of adsorbent have been studied. It is found that TSS(total suspended solids) is reduced from 350 ppm to 15-20ppm, total BOD from 250ppm to 10-20 ppm and ph dropped from highly alkaline range to 8.5-9.5 range, reduction of 80% in total soap content, FOG(fats, oils and grease)from visible turbid level to non turbid and clear solution. It is also reported here that for efficient treatment of domestic wash water waste adsorbent dosage of 40g/L is recommended.
Solid waste means any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials including solid, liquid, semi-solid, or contained gaseous material, resulting from industrial, commercial, mining and agricultural operations, and from community activities.

Performance Evaluation of 9 MLD Sewage Treatment Plant at Gurgaon and Cost Ef...civej
Sewage treatment plant under study has 9 MLD capacity and is located in Gurgaon. It receives sewage from the surrounding residential areas and after three stage treatment, treated effluent is supplied back to meet water requirement for various purposes. This has certainly reduced dependency on the precious underground water and thereby reducing the burden and saving environment. For performance evaluation of the sewage treatment plant samples were collected at various stages i.e., at inlet raw sewage, after primary treatment, secondary treatment and after tertiary treatment. Samples were tested to measure various parameters like pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Total Suspended Solids (TSS), Total Kjedahl Nitrogen (TKN), Total Coliform, Phosphorous and Oil & Grease. Data on above parameters were observed and collected for three months November, 2014 to January, 2015. All these treatment are adding a huge cost to the recycled water. Hence the present study is aimed to provide alternatives to reduce the cost input. Also studies were made to find out ways by minimizing processes and stages of treatment.
Arsenic in Tube Well Water in Six Blocks of Supaul District, Bihariosrjce
An experimental estimation of arsenic in a large number of samples by Field Test Kits and by
Hydride Generation Atomic Absorption Spectrophotometer (HGAAS) was done. Water samples were collected
from the following blocks of Supaul district, viz., Raghopur, Basantpur, Supaul, Nirmali, Saraigarh-Bhaptiyahi
and Triveniganj. The aim of this study was to analyze the total arsenic concentration in tube well water of these
regions at different locations. Twenty water samples were randomly selected from each block (n=120) for the
determination of Arsenic concentration, using Field Test Kits. Few samples (n=11) found with higher
concentration of arsenic, were also estimated and confirmed by HGAAS method for comparative observation.
The maximum concentration of arsenic was found to be 0.10 mg/l by using Field Test Kits method and the
average concentration of arsenic of the selected samples was 0.02 mg/l, whereas around 20% of these tube
wells had arsenic concentration above 0.05 mg/l. It was observed that the results obtained by usingField Test
Kits showed less measurement as compared to those obtained by HGAAS method for the same samples, when
the arsenic concentration measured ≤0.10 mg/l. Arsenic concentration was significantly (p<0.0001) higher in
HGASS results than the value obtained by Field Test Kit method.

Abstract Ultrasonicated Membrane Anaerobic System UMAS was successfully used for sewage sludge treatment and biogas production. Central Composite Design and Response Surface Methodology were used to determine the optimum conditions in which UMAS produce a maximum content of methane in the biogas produced. The effects of three variables namely pH, chemical oxygen demand (COD) and organic loading rate (OLR) on methane content were evaluated individually and interactively. The optimum conditions obtained were pH 7.74, COD 1061.06 Mg/l and OLR 0.90 kg/m3d. The predicted maximum percentage of methane was 89.72 % and confirmed close to RSM result.

This study investigates the influence of silicone antifoam agent on waste water from Gashash leather
and Nigerian Spinning and Dying industries (NSD). Waste water from the outlet of the industries were
collected and analyzed for physicochemical parameters. Silicone antifoam was added to the wastewater to
determine the impact of the silicone antifoam on turbidity and chemical oxygen demand (COD)
concentrations. The result shows that both turbidity and COD values significantly increased even when small
concentration of the silicone antifoam was added. Further, independent t-test was used to identify the
variance between the mean value of the wastewater from leather, spinning and dying industries, the results
indicated that there are no significant differences (observed t 0.544, critical t 2.015, and p value 0.589)
between the waste water in leather and dying industries.

RECYCLING OF GREY WATER INTO USABLE WATER BY USING NATURAL MATERIALSvivatechijri
Recycling of Grey water generated from different industries by using the natural filter materials
and making the water reusable for sanitary and irrigation purposes. The aim is to reduce the costly recyclable
process of grey water to its minimum cost, hence making it suitable for village and low-income areaswhen such
water can be treated at place with less cost and by achieving almost same quality of water. In view of rising
concern about pollution of water bodies due to discharge of waste in them, itis necessary to initiate alternative
thinking as conventional methodsthrough Sewage treatment Plants have had limited success. In Rural areas we
have some natural materials which can purify the water if used properly. In recent years many techniques by
using such natural filters for purifying Grey water had came up. It treats the wastewater in natural manner
without the use of chemicals. In short, the method used for this project is the improved method of using natural
materials for recycling Grey water and obtaining best quality of recycled Grey water. The main objective of
present research work is to provide and popularize a simple, feasible, practically sound, ecofriendly and costeffective technology for wastewatertreatment. In this filterthe filtration is done by gravitationalforce. By using
such Techniques, the load on the sewage impact will be reduced and will be converted into useable water for
sanitary, gardening and irrigation purposes
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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
