Wastewater treatment is a scientific procedure for treating sewage water to ensure it is suitable for reuse. Guidelines for preparing a wastewater treatment plant for individual homes are available in under Section 76 of the Environmental Protection Agency (EPA) Act, 1992 and its subsequent amendments.
The performance evaluation of the treatment plant can be found through systematic sourcing of parameters about the construction and maintenance of such systems. There are lots of criteria for appraisal of performance criteria. The whole process of the wastewater treatment is performed in three prime parts of functional scopes.
Defining site characterization of a residential septic system is the first step of the installation. A variety of steps are included in the evaluation of the site characterization.
On-Site Assessment – Understanding the scope of the job and initial planning of this installation and requirements is quite essential and on-site assessment can help to define the precise extent. Participation of government and involved members at a desk duty can help to create the perfect plan.
Plan – The plan for installation of the water treatment requires consideration of release route, website improvement, and potential penetration levels for water to reach underground reservoirs, and recommendations to enhance the process speed.
Systems of Septic Tanks – ‘Compact treatment tank’ (which is also known as ‘ถังบำบัดน้ำเสียขนาดเล็ก’ in the Thai language).play a pivotal role in delivering superior water treatment benefits. Determination of the sludge storage capacity is the important aspect whilst contemplating the septic tank system. This also decides the possible dwelling capacity. Ordinarily, a septic tank of 10.2m2 sizes is acceptable for a two – bedroom home.
Percolation Spots – The place for percolation is quite important for infiltration of water. Several relevant aspects like percolation trench parts and raised percolation areas will need to be given detailed attention. Several parallel infiltration methods can be found, yet the procedure selection has to be done according to the on-site requirements.
What are the secondary and tertiary sewage treatment systems?
Secondary and tertiary treatment systems primarily focus on aspects like rotating biological contactor, membrane filtration, biological aerated filter, media filter systems, sequencing batch reactors, constructed wetlands, polishing filters, tanks, and pipework.
Additionally, immediate attention is needed to consider the effects of sub-soil layers and ground slope. These factors govern the sustainability of the wastewater treatment systems. Fixing effluents in a systematic manner is extremely vital to avoid groundwater contaminations and possible health hazards. Proper setup of the treatment system has to be accepted by concerned governments during preparation, installation, and execution phases.
