Domestic wastewater is the water flowing from your home's kitchen, toilets and bathrooms into the drainage pipes. This water finally drains into your septic tank. The water contains contaminants and pollutants that might degrade the environment if allowed to flow out without treatment.

Thus, to ensure that your domestic wastewater is safe for the environment, you must treat it properly before releasing it. Releasing an environmentally friendly effluent reduces the harmful impact of sewage on the surface and underground water.

For that reason, you need to have a domestic wastewater treatment system. A well-maintained system should remove all the bacteria, infectious viruses, chemicals and solid materials from the wastewater, making it safe for release and reuse. The system cleans the water in three basic steps, as discussed below:

The Primary Stage

This stage involves the removal of the solids from the wastewater. The primary chamber contains a screen that separates sticks, stones or any other large objects from the water. It also includes a grit compartment, which allows suspended particles such as food debris, hair and paper to settle at the bottom. Together with floating grease and scam, these solids are separated from the liquid waste, which then moves to the secondary chamber.

The Secondary Stage

The water flowing in this treatment system only has small suspended particles that need a few techniques to eliminate. The main purpose of the secondary tank is to eradicate this organic matter. 

Bacteria facilitate the process of decomposition of organic matter. For that reason, many domestic wastewater treatment systems contain an air pump used to aerate the chamber in order to encourage bacteria growth. Usually, the water has to go through many cycles to achieve maximum decomposition. After several circulations, the wastewater is around 90% clean and ready to move to the next chamber. 

The Tertiary Stage

The tertiary phase is the final cleaning stage before you release out the water. In this stage, there is the removal of all the remaining harmful substances in the wastewater. If there are any fine particles still present in the water, they are allowed to settle at the bottom of the tank. You can also disinfect the water at this point if you intend to reuse it in your home.

Installing a domestic wastewater treatment system is a worthwhile investment. You can reuse the water in lawn care, car-washing and watering your garden. More importantly, treating your domestic wastewater shows your concern for the environment. But for effective treatment, engage an experienced septic tank service for regular inspection and servicing of the system.
