Wastewater Treatment in Food Manufacturing


Within the manufacturing process, there's a flow of wastewater that contains various pollutants. If left untreated, it can harm ecosystems, water bodies, and biodiversity. Sustainable wastewater management uses advanced wastewater treatment technologies and eco-friendly strategies to handle this waste, helping food manufacturers adopt environmentally friendly practices.

For food manufacturers, this means more than expected. Implementing sustainable wastewater management practices can set them apart in the market, attracting loyal, eco-conscious consumers.


Industrial Wastewater Treatment Process in Malaysia

Wastewater treatment deals with the management and treatment of water that's been contaminated by industrial activities. Each industry generates specific types of wastewaters; hence all treatment processes may not suit all kinds when it comes to mitigating the varsity of pollutants present in it.


Primary Wastewater Treatment

The first step is known as primary treatment. This phase uses gravity to help separate suspended solid waste from the water via sedimentation tanks. This processing stage doesn't remove smaller particles or dissolved substances but plays an essential role in reducing total suspended solids (TSS).


Secondary Wastewater Treatment

Secondary treatment enhances the work begun during primary processing by focusing on biodegradable constituents left over from primary treatment. It often involves biological processes, including activated sludge process, using microorganisms to break down harmful contents like nitrogen and phosphorus.

Over time, however, newer technologies have emerged like Membrane Bioreactors (MBR). MBR integrates both secondary and tertiary treatments into one method - simplifying operations while increasing efficiency.


Tertiary Wastewater Treatment

Finally, there's tertiary treatment, which eliminates leftover particles through disinfection methods such as chlorination or UV irradiation before releasing it back into nature. This step ensures that whatever's left wouldn't harm ecosystems by maintaining a certain quality standard for release.


Specific Pollutants in Food Manufacturing Industry Wastewater

Wastewater from food manufacturing can hold different pollutants, depending on the food type. Some common ones are:

  • Biochemical Oxygen Demand (BOD): Measures microorganisms' oxygen needs to break down organic matter.
  • Chemical Oxygen Demand (COD): Measures oxygen needed for chemically oxidising organic matter.
  • Total Suspended Solids (TSS): Gauges suspended solid particles, including fats, oils, grease, and cleaning residues.


Risks of Not Treating Industrial Wastewater

There are many risks associated with not treating industrial wastewater. These risks can impact human health, the environment, and the economy.


Impact on Human Health

Waterborne Diseases

Pathogens spread through contaminated water, causing illnesses.


Harmful pollutants can lead to respiratory, skin issues, and cancer.

Nutrient Pollution

Excessive nutrients cause harmful algae blooms and unsafe water.


Impact on the Environment

Water Pollution

Discharging wastewater pollutes water bodies, harming aquatic life.

Groundwater Contamination

Polluted wastewater infiltrates and contaminates groundwater.

Ecosystem Damage

Untreated waste disrupts ecosystems, harming plants and animals.


Impact on the Economy

Healthcare Costs

Treating waterborne illnesses is expensive.

Environmental Clean-up Costs

Remedying polluted areas is costly.

Property Damage

Untreated wastewater damages property.

Tourism Loss

Contaminated areas deter tourists, affecting the local economy
