WASTE water treatment project........ Wastewater treatment is a process used to convert dirty wastewater into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can then be used for other purposes. The treatment process takes place in a wastewater treatment plant (WWTP), often referred to as a Water Resource Recovery Facility (WRRF) or a sewage treatment plant. Pollutants in municipal wastewater (households and small industries) are removed or broken down.
The treatment of wastewater is part of the overarching field of sanitation. Sanitation also includes the management of human waste and solid waste as well as stormwater (drainage) management.[1] By-products from wastewater treatment plants, such as screenings, grit and sewage sludge may also be treated in a wastewater treatment plant.[2]:Ch.14

Rainwater harvesting collects rainwater from rooftops in tanks for non-potable uses like toilet flushing and gardening. It can save 30-50% of drinking water usage. A typical system filters rainwater into a buried storage tank, from which a pump distributes it through a separate piping system. Greywater recycling cleans and filters used water from baths and sinks for similar reuse, saving up to 40% of drinking water. Combining the two systems maximizes water savings.

Effect of basic pretreatment on saccharification of water hyacinth
Abstract The world has seen a vast expansion in industrialization and this has in turn seen an increase in demand for fossil fuels. To sustain such a pace of development, these fuels are being consumed at a rapid rate. This dependence on the fuels coupled with their rapid rate of depletion has called for research to look for alternative fuels. Biofuels like bio-ethanol and bio-diesel are being considered as replacements. Bio-ethanol is being given special consideration, as it can be used as a substitute to, or as a blend with petrol in existing gasoline engines, without much modifications being made to these engines. The substrates under consideration are that of the biomass genre, and Water Hyacinth being of special importance.. Water Hyacinth is an aquatic weed which grows in most tropical parts of the world. It has considerably lower lignin and higher cellulosic content, which makes it a suitable substrate for bio-ethanol production. The three main steps for bio-ethanol production are pretreatment, which makes the biomass amenable to further treatment, Saccharification, the process by which complex sugars are broken down to simple reducing sugars and fermentation, where the sugars are fermented by the action of relevant fungi. This study focusses on the Saccharification step of the process, specifically focusing on the effect of pretreatment on the Saccharification of Water Hyacinth. Three samples of powdered Water Hyacinth, along with 3 samples of Base pretreated Water Hyacinth powder were subjected to the Saccharification process using TrichodermaViride. It was observed that the Saccharification yields for the pretreated samples were in excess of 200% greater than that of the Saccharification yields of the powdered Water Hyacinth samples without pretreatment. These results were observed on the day 2 of the process. The results of this study will be taken into consideration for the fermentation step of the process. Keywords: Water Hyacinth, Pretreatment, Saccharification, Reducing sugar yield, High yields.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Treatment of liquid waste
- 1. Treatment of Liquid waste At the hotel the water is recycled through latest technology. The hotel in its premises itself has a sewage treatment plant in this the liquid waste goes under primary and secondary treatment. The wastewater comes from two ways first from the kitchen and secondly from the restrooms of the hotels. This water first undergoes the process in which water is separated from oil. Then the water is passed on to another tank in which the dust particles settle down at the bottom of the tank and the clean water stays at top of the tank. Then the water is passed on to another tank in which minute dust particles are removed. Now the water goes for the secondary process that is the filtration. The water is purified and collected in a tank. And after this the purified water is hard so to make it soft a softener is used. This water is used for air conditions and gardens.
