Three Main Objectives Of A Faecal Sludge Treatment Plant

Posted On: 31st July, 2023

A sanitation system deals with human faeces and urine from the time it’s generated until it’s used and disposed of in a safe manner. To cut down the environmental and health risks, the fourth component of a non-sewered sanitation system fixes treating faecal sludge. A lack of efficient treatment options is why faecal sludge is dumped into the environment. This reduces the pros of having on-site sanitation features.

The level of treatment will rely on the final objective for the faecal sludge. A faecal sludge treatment plant can reduce the pathogens to a safe level. Or it can turn faecal sludge into a useful product with environmental and economic benefits. This process is known as “resource recovery”. The treatment plant helps deal with and reduce the bad impacts of faecal sludge. It also helps in increasing the potential positive impacts.

What Are the Key Objectives of the Treatment Plan?



Usually, there is a high water content in faecal sludge, and dewatering removes water from it. As water is heavy, dewatering reduces the volume and weight of sludge, making it cheaper, safer, and easier to manage. This also attracts fewer rats and flies, as well as smells. Moreover, the more water in faecal sludge, the higher the groundwater and surface contamination risk.  

Pathogen inactivation

One of the main objectives of a faecal sludge treatment plant is pathogen reduction to secure public health. Pathogens are viruses, helminths, bacteria and protozoa that cause disease. The final use or disposal of faecal sludge determines the level of pathogen reduction. There are many ways by which a faecal sludge treatment plant inactivates pathogens.

Nutrient management

There are nutrients in faecal sludge, like potassium, nitrogen and phosphorus. These are essential to the growth of a plant. Farmers use these nutrients to increase the productivity of crops. However, these can infiltrate via soil into groundwater or be transferred by rainwater to surface water bodies. They can harm both the environment and drinking water.

Nutrient management is about altering the form of nutrients, from solid to liquid, inorganic to organic, etc. During the treatment, the nutrients are transformed and stabilised.
