How do advanced secondary Home Sewage Treatment Plants work?

Do you need to know how an advanced secondary Home Sewage Treatment Plant or HSTP works? You might be looking at options for investing in an onsite sewage system for a new home or renovation. Some home sites are large, with few site constraints or environmental concerns. They can be serviced with a traditional primary septic system. However, under current legislation the majority of homes require secondary treatment of their household wastewater via a HSTP. But what is a Home Sewage Treatment Plant and how do they work?

Home Sewage Treatment Plants (HSTPs) play a crucial role in the treatment of household sewage before dispersal to the environment. Also known as domestic on-site sewage management systems, they are used in areas without access to municipal sewage connections.

Domestic sewage systems need state government accreditation before they are approved for install. An accreditation shows that a home wastewater system has been tested at an authorized testing facility. Accreditation is peace of mind for homeowners. True Water work closely with Fuji Clean Australia to deliver high-quality home sewage treatment systems. Their ACE1200 advanced secondary treatment plants surpass the current accreditation requirements and are our system of choice for trouble free operation.

Home sewage treatment plants are installed below ground and work to treat household wastewater to an advanced secondary standard before dispersal to the environment.

How the Secondary Sewage Treatment Process Works

Modern HSTPs use secondary treatment processes to manage your household wastewater within multiple chambers. Specific environments are created to encourage natural processes using bacteria to treat the wastewater to a high level. Wastewater from a home’s kitchen, laundry, bathroom, and toilet flows to the HSTP in the garden. From there, the wastewater goes through a series of treatment processes before being dispersed in the soil of the garden. The soil and vegetation provide the final filtration as the water re-enters the environment.

Here’s how our advanced secondary Fuji Clean Home Sewage Treatment Plants work:

1. Pre-Treatment:

To begin with, wastewater from the household enters the treatment system and undergoes initial pre-treatment. This stage may involve the removal of large solids and debris through a physical screening process or a grit chamber to prevent clogging and damage to downstream components.

2. Primary Treatment:

After pre-treatment, the wastewater enters a primary treatment chamber. Here, solid particles settle to the bottom of the chamber, forming sludge, while lighter materials such as grease and oils float to the surface to form scum. Mechanical devices or natural processes facilitate the separation of solids and liquids.

3. Biological Treatment:

The separated wastewater then undergoes biological treatment in aerobic or anaerobic environments. In aerobic treatment, aerobic bacteria are introduced into the wastewater, and oxygen is supplied to support their growth. As a result, these bacteria break down organic matter and nutrients, further reducing the pollutant load. Similarly in anaerobic treatment, anaerobic bacteria break down organic matter in the absence of oxygen, producing biogas as a byproduct.

4. Clarification and Filtration:

In addition, the treated wastewater may pass through clarification or filtration systems to remove remaining suspended solids and impurities. This helps to improve the clarity and quality of the effluent before discharge.

5. Disinfection:

Further, the effluent may undergo disinfection to eliminate any remaining pathogens or harmful microorganisms. Common disinfection methods include chlorination, UV irradiation, or ozonation.

5. Effluent Dispersal or Reuse:

Effluent is then safely dispersed into the environment, through a Land Application Area which is designed in accordance with site-specific conditions and local regulation.
