Most Efficient Methods Greywater Treatment â€Myassignmenthelp.Com

Question: Discuss About The Most Efficient Methods For Greywater Treatment? Answer: Introducation Most of the grey water coming from kitchen appliances, washing machines, and bath sinks is termed as wastewater yet it can be recycled and made safe for human consumption. It is out of this observation whereby this paper strives to explore the environmentally friendly systems that can be used for grey water treatment. When greywater is recycled, it can be subjected to several uses that provide several benefits to the users. For example, the studies indicate that with the proper greywater treatment, it can be put into effective use such as irrigating plants, toilet flushing, and laundering(Khalid Edward, 2012). Secondly, treatment of greywater reduces the need for fresh water, a practice that translates into reduced household water bills and public demand for water supply. Thirdly, the reuse of the greywater reduces the amount of wastewater being channeled into sewage treatment systems(Abu, Grietje, Francis Group, 2012). Putting into consideration the numerous benefits of treating g reywater, the challenge remains to determine the most effective and efficient ways to treat it. Pidou, Memon, Stephenson, Jefferson, Jeffrey (2014) highlighted that there are many methods through which greywater can be reused. In support, Ukpong Agunwamba (2012) asserted that the methods used should not be harmful to the environment. Greywater Treatment Systems Methods used for greywater treatment should be robust enough to eliminate health risk associated with its improper treatment(Khalid Edward, 2012). Ajit (2016) explored that grey water is associated with pathogens such as viruses, protozoa, and bacteria which are harmful to the waste water users. Therefore, it is important for the wastewater treatment process to apply accurate water treatment procedures. In the following discussion, this report will discuss waste water treatment systems that have been found to be effective. G-Flow Greywater Treatment System The G-Flow is a low is a greywater treatment system that collects water from bath sinks, washing machine and shower and automatically divert, filter and disperse it to the garden through the drip line irrigation system(Alcott, 2013). This system eliminates the need for sprinkler irrigation in the garden(Baobab Water Solutions, 2015). Different areas of the garden are automatically watered when someone showers, wash clothes or utensils. The G-Flow grey water treatment system has proved to be one of the most effective wastewater treatment systems that help to combat drought and water restrictions. The application of G-flow greywater system involves filtering and pumping basin, shower and laundry water and diverting it for irrigation in the gardens. Originally, the G-flow system was designed to help the pumping of waste greywater to the gardens. However, currently, the system can be used to for treating grey water to be used in flushing toilets. Guy Green (2014) proves that over ten thousand G-flow systems have been sold globally and they have been found to have overwhelming results by saving over fifty thousand gallons per household within a year. The system costs $600. The benefits associated with the system have superseded the cost incurred to purchase it. Besides, the system is economical to run, simple to use and easy to install. However, the system has been found to only work properly with the gray water with biodegradable and environmentally detergents(Smart Water Solutions Pty, 2015). Grey Flow PS System The Grey Flow PS System is another greywater treatment method. It is a whole house of the greywater diversion system that is installed below the ground(Khalaphallah, 2012). The Grey Flow PS system has an automatic backflush filtration. The system directly diverts washing clothes and showering greywater into the underground water tank which then directs it into the garden. The Grey Flow PS System is designed in a manner that it can fit into almost any household. Unlike other systems, the Grey Flow PS System is associated with specific benefits such as reducing bacteria and mosquito breeding grounds and health risks attributable to the open greywater treatment systems(Jabornig, 2014). Its cost ranges between $1,150.00 and $1,850.00. Constructed Wetlands Greywater Treatment System The constructed wetlands is a greywater treatment system that involves the use of natural processes such as wetland soil and vegetation and other microbial substances to enhance the quality of wastewater(Narges , Hasan, Nafise, Mahmood, 2015). The constructed wetlands act as a sieve whereby it purifies wastewater by removing nutrients and filtering sediments from greywater. Apart from purifying grey water for irrigation, this system has also been found to purify and treat water destined for discharge into the pond, river, local creek, and estuary. Scientists have agreed that this is the most effective way of treating water meant to be discharged to the wildlife habitat(Bani-Melhem, Al-Qodah, Al-Shannag, Qasaimeh, 2015). Besides, this system can be integrated with other systems to treat water for the toilet flushing. Jaboring (2013) concluded that wetland system is the most counterproductive system for the households who want to use grey water for irrigation purposes. The cost of in stalling is less than $100.00 because the system largely relies on the natural resources of which most of them are locally available. The Aerated Wastewater Treatment System The aerated wastewater treatment system is a biological process that efficiently removes or reduces the organic matter in the grey water(Nirmala, Muthukumar, Ravikumar, 2016). This system allows water to flow through several chambers that progressively filter and treat the wastewater. The system comprises of the several chambers. In the first chamber, the solids in the water are allowed to settle through the process of anaerobic decomposition. In the second chamber, the effluent from the first chamber is aerated through pumping of the air. The third chamber involves clarification whereby the effluent from the second chamber is allowed to settle then it is pumped back to the first chamber. Finally, the fourth chamber discharges the treated water into the disposal field. Water coming from this system can be used for toilet flushing or gardening. The installation and maintenance cost of this system may go up to $2,000.00 Aerobic Sand and Textile Filter Greywater Treatment System The aerobic sand and textile filter grey water treatment system are used to remove large particles from grey water coming from kitchen sinks. Scholars advocate that it is highly recommended to use this system if wastewater contains large particles such as foods and detergent pieces(Ghaitidak Yadav, 2013). The system treats and filter the effluent in the best way and does not contribute to environmental pollution. Ideally, for the system to work, it has to be supported by a three-stage septic tank. This tank is used for the grease and sludge isolation. The separated sludge is usually removed bi-yearly. Immediately after the septic tank, there is a sand filter that is designed in a manner that allows aerobic conditions to take place. Finally, the wastewater in the treatment processes is purified in a planter-bed and discharged to the target destination. Water realized from this system can be used for plant irrigation or toilet flushing. Almoayied, Jonathan, Steven (2014) maintains th at this is the most effective and simple system to maintain. Similarly, the system proves to be inexpensively provided that it can go for $500.00 Planter Soil Box System The planter soil box system has been used as early as in the 1970s and it has been proven to be one of the most effective methods of purifying and treating greywater. The environmentalists have maintained that the system produces excellent results(Ghaitidak Yadav, 2013). The system works well when the planter is properly drained to avoid the formation of water-logged zones in it. At the bottom of the planter, pea gravel is preferred to offer effective drainage. A thin net like layer that is equivalent to the mosquito-netting is placed on top of the peak gravel to prevent next layer of the coarse sand from falling through the bottom layer. The layer above the second layer from the bottom comprises of the normal mixture of sand. Finally, the top most layer consists of humus-rich top soil. The wastewater is filtered and treated through this layers and can be used for plant irrigation. The water produced from this system can be used for heating purposes, irrigating planting beds or even for flushing toilets. It approximately costs $1000.00 to install the whole system. Discussion on Greywater Treatment Systems The above discussion makes it clear that different ways can be used to treat greywater. The environmental friendly techniques come out as the best wastewater treatment systems. Environmental conservatives hold that different water treatment methods must be safe and not harmful to the environment. All the above methods discussed in this paper meets the two criteria. This is because they have largely relied on the utilization of natural resources such as microorganisms, plants, and soil to treat greywater that can be safely used again. Therefore, the wastewater treatment system used in this report have proved to improve local environment through availing safe water to it without an element of pollution. References lambe , J.
