Onsite Wastewater Management

Question: Discuss about the Onsite Wastewater Management. Answer: Introduction: Depending on the environmental situation and other pollution management conditions different technologies are considered for the onsite treatment (McLellan Corder, (2013). Different onsite treatment methods are used by the system developers such as septic tanks, intermittent sand filters, aerobic treatment units, nutrients removal systems and wastewater segregation and recycle systems. The advantages and disadvantages of the technologies and its brief descriptions are as follows: Wastewater segregation and recycle systems This is one of the most widely used technologies used to modify the quality of the wastewater. For the onsite treatment this processes are referred to as important components. This technology helps to remove massive rate of pollutants from the wastewater for make further treatment or disposal. For the selected natural materials the estimated phosphorus adsorption rate also differs. Implementation of mound system is very much helpful for onsite treatment. The mound system helps to mitigate the restriction of sites. Media Adsorption rate Acid soil outwash 10-35 Calcareous soil outwash 5-30 Sandy soils 2-20 F-1 Alumina 700-1500 Over the centralized treatment plants the onsite treatment method has become one of the most widely used technologies. Onsite treatment also provides efficient sanitation process. After adaptation of this process, the users will be able to get services in a cost effective and timely manner. Membrane bio-reactor is a compact system that is much scalable to the future capacity. Even the maintenance cost and the system is completely automated. It can accept highest capacity load. In order to deliver the expected outcomes, high level operating training is needed. Even for the mixing process, higher energy is required. Higher energy for the treatment is required Due to the size of the system larger footprint and high level maintenance is needed that is quite expensive. Pretreatment technologies This is one of the most advanced technologies used for the onsite treatment. This advanced treatment step delivers to further for reducing solids and as well as FOG concentration in the wastewater. It also has the capability to reduce the possible nutrients concentrations. Two different ways might be used for developing the system efficiently. In a single processing tank there will be different separated tanks and the FOG and solids will be separated in those tanks. Before the drain field option and just after the septic tank, a separation component is located (Dutt King, 2014). In order to create an oxygenated environment, different aerobic treatment units are relied in the air injection units. Pros and cons of the technology In order to break down the organic materials this technology is found to be very much helpful as it supports bacterial population control system efficiently. In the aerobic portion the solids and the bacteria s can be settled down It also helps to develop additional treatment programs Clarification is referred to as another important part for the treatment rater for the onsite treatment. If non-absorbent materials are identified then, it will be harmful for the micro elements. If the media filter approach fails to meet the requirement of the onsite treatment development then, it will lead to major failure for the waste management system. Decentralized onsite wastewater technologies This is another technology that is widely used in the sustainable green infrastructure that protects the original source of the water quality and the public health at the same time. In United States and Canada most of the water most of the waste water is generated daily with the help of decentralized technology (Ouakibi et al., 2013). Comparatively than the sophisticated centralized wastewater treatment plant, onsite systems are capable to serve properly designed, installed and operated treatment. It provides outstanding treatment capabilities This is required to be considered as a permanent part for the infrastructure of the wastewater management system The installation and operation both are very must easier than other technologies Possible recycling approach is also available in this management system It needs less amount energy for moving the swage around the system Due to gravity flow collection no proper the soil absorption approach is not applicable and reliable at the same time. If proper and responsible operations are not used then it will lead to major failure and also for that reason the organic elements living in the soil will get harmed. For increasing complexity to single management framework was found to be efficient for developing the system. References Abdelaziz, A. E., Leite, G. B., Belhaj, M. A., Hallenbeck, P. C. (2014).
