4 Common Methods of Sewage Treatment
Sewage and wastewater are usually gathered and conveyed by sanitary sewers. Within the sewer line, there are dangerous chemical solutions and wastes that could affect our health and our environment. It is a must for each area to have their various ways of disposing of their wastewater and sewages to avert these hazardous substances from having a directing contact with humans and animals. Most of the people refer to this as community sewage system. The aforementioned has various methods which can be utilised for sewage treatment. Here are the following:
This known disposal method gathers the entire sewages from your house’s sinks, bathrooms, laundries, toilets and carried them until it reaches to the septic tank. French drains are an example of effluent disposals where sewages that come from the septic tank are disposed and released. This type of method disposes of the sewage in the soil where it is closed to it. Keep in mind that when there are any complications, this shouldn’t be handled by an individual only and should only be repaired by professionals who already have experience in handling the problem. Moreover, on-site disposal is not appropriate for installation in some specific districts due to the danger it may bring to the area most especially if the area is under these conditions:
- Flood is frequent
When flood often happens to your area, this type of method is not fit for you. In the course of a flood, the soil that is nearby the treatment plant where sewages are deemed to be soaked might wear away and disperse into your place. As the sewage spread, it invites insects and diseases that hold health hazards as it comes in.
- Places with high water table
If the water table in your place is high, that indicates that it is near the ground. It can be polluted as the treatment plant discharges sewage that may cause contamination and pollution.
- Areas with a lot of sewages
For areas with a huge population, they tend to have a bigger amount of sewage in contrast to those areas which lesser occupants. Due to the number of occupants, the discharges sewage might be too large to be placed into its surrounding soil.
- Areas close to drinking water suppliers
Like the other mentioned, as the sewage is released to place near drinking water suppliers, the chances of polluting and contaminating the water is high. This not only affects the water supply but also the health of the water consumers.
For effluent disposal method, French and leach isn’t present at all. As they gather sewages from building, schools, communities and households, they treated these sewages most often in the lagoon. There are two places where it can be treated, either in the lagoon or in your community’s septic tank.
Full sewage system
For this type of method, sewages that come from the large communities, household and other establishments aren’t treated in various septic tanks. These sewages are pumped on the way to the lagoon as they penetrate the sewer pipe. As it enters the lagoon, these are to be crushed as they flow to a set of blades known as macerators. For some odd situations, there will be a large septic tank that will place before the lagoon so that sewages are already treated.
Off-site disposal method is a sewage treatment typically utilised in over populated or in urban areas. The sewage is collected and conveyed to a larger sewer line before transporting it into the treatment plant and released into a body of water.
