Let's get to know septic tanks and how to choose.

Wastewater treatment tank It is a prefabricated tank that combines both a seepage tank and a septic tank into one. Used for containing waste that we excrete such as feces or urine. It works by using microorganisms to remove microorganisms from waste. which flows into the ready-made wastewater treatment tank. and will settle at the bottom of the tank filled with microorganisms waiting to decompose. This results in no odor and no sediment remaining in the tank. The water that has been treated It can be dumped into public drains. The wastewater treatment tank will be installed underground. This makes maintenance quite difficult. Therefore, it is necessary to choose a quality tank that passes TIS standards, including choosing the appropriate type of wastewater treatment tank. and sellers with after-sales service For the most efficient use.

Types of septic tanks

Septic Aeration Tank : It is a round shaped wastewater treatment tank. that has an air pump system installed To help add air to the inside of the treatment tank. and helps increase oxygen to the microorganisms inside the treatment tank Can be used to decompose dirt. or waste more efficiently This makes wastewater treated with aerated septic tanks have less bad odor. Likewise, the BOD value also decreases, meaning that wastewater that has been improved with this type of tank will be clean. and is more environmentally friendly than a wastewater treatment tank without aeration.
- Interesting terminology : BOD (Biochemical Oxygen Demand) is a measure of spoilage from water used for consumption that is dumped into public water sources. or from leaf scraps which will show the amount of oxygen that bacteria need to use to decompose organic matter

Simply put, if wastewater has a low BOD value, when it is dumped into a water source it will not affect that water source. This is because bacteria require less oxygen to decompose. But if wastewater has a high BOD value when it is dumped into water sources It will cause the amount of oxygen in water sources to decrease greatly. Until living things in the water source cannot survive.

Septic Anaerobic Tank : It is a treatment tank that is popular for use widely in homes. Including offices with a small number of employees. Because it is more affordable than an aerated septic tank. But in exchange, it helps decompose waste quickly, including reduced microbial waste inside the treatment tank as well. Therefore, it can be observed that the wastewater obtained from improving the quality with a wastewater treatment tank without aeration. May emit a more unpleasant odor than using a general aerated water storage tank.

Materials used to produce wastewater treatment tanks

Plastic septic tanks : Made from high quality polyethylene plastic. (Polyethylene: PE) makes it have good properties in terms of strength, durability, and can support a lot of weight. and can withstand relatively high acidity and alkalinity. in the area under the ground very well It can also help prevent moisture penetration effectively.
Fiberglass septic tanks : Made from fiberglass. that were reinforced with plastic resin This makes this type of tank very strong and durable. There is also no problem with breakage or leakage even though it has been used for a long time Therefore, it is suitable for use as a wastewater treatment tank in condominium projects, hotels, or large industrial plants. which has a large amount of wastewater to handle each day

Choose a septic tanks that is suitable for your use

Consider the suitability of the area. Using an area approximately 1 meter wide or larger than the size of the septic tank. The depth is appropriate for the size of the septic tank. and build a base to support the septic tank with cement. Along with checking for scraps that may damage the septic tank.
Consider the material of the septic tank. For strength and durability in use, for example, a PE tank will last approximately 10 years. The material is strong. Not easily broken It is durable against acids, alkalis and chemicals. Can support weight and prevents moisture leakage problems well
Consider the budget for maintenance. Because after installation There will be a cost to suck up the waste after it undergoes decomposition of bacteria and organic matter. out of the septic tank
Consider the size of the septic tank. The basic calculation method is the size of the wastewater treatment tank (liters) = number of people living in the house x (volume of water used/day/people living in the house x 80%) x time used to treat wastewater each time ( Estimated is 2 days) According to the law, land allocation standards should use a septic tank size of 1,600 liters / 1 house.
Consider reliable sources of septic tank sales. such as purchasing through a leading department store. or through the company directly There are a variety of septic tank sizes to choose from. Suitable for needs There is after-sales service. And there is a quality guarantee.

Take care of the septic tank so that it works well.

Do not throw things that can cause blockages, such as sanitary napkins, thick tissues, or small items, into the toilet. Because these materials are difficult for microorganisms to decompose. This will cause the septic tank to fill up faster than normal and cause the pipe to become clogged.
The septic tank should be pumped even if it is not yet full. Users should pump the septic tank every 1-2 years, even if the septic tank is not yet full. In order for the septic tank to always have good treatment efficiency. It also prevents sediment from accumulating in the anaerobic filter pond.
Always observe the water flow. You should check regularly to see if the water flows normally or not. Are you stuck? Most of the time, the blocked flow may be caused by large pieces of material blocking the pipe or because the pipe has collapsed. Consider solving each case on a case-by-case basis.
In the case that other equipment must be used, such as a water pump. air dryer Follow the device's manufacturer's instructions. Or contact an expert technician to check.
