Natural Ways to Get Rid of Bad Smells in Wastewater
Bad smells from wastewater are something almost everyone has encountered at some point. Whether it is a lingering odour from a drain, the unpleasant stench near a septic tank, or a stronger problem at a larger wastewater site, foul smells are both uncomfortable and concerning. Many people try to cover up these smells with chemical products or deodorisers, but that often only masks the problem rather than solving it. In fact, relying on chemicals can sometimes make the issue worse by harming the balance of the environment.
Fortunately, there are natural, effective ways to deal with wastewater odours. At Bioglobe, we specialise in organic enzyme remediation – a safe, eco-friendly method that tackles the root cause of the smell rather than simply covering it up. By breaking down the pollutants that create bad odours, our tailored enzyme solutions restore balance without causing any harm to people, wildlife, or the wider ecosystem.
In this article, we will explore the problem of wastewater odours, the consequences if they are left untreated, and the natural solutions that Bioglobe can provide. By the end, you will see why enzymes are such a powerful ally in cleaning up wastewater safely and sustainably.
Understanding the Problem
What Causes Wastewater to Smell?
Wastewater is essentially used water that carries away waste materials. This includes household sewage, food residues, fats, oils, soaps, chemicals from cleaning products, and sometimes industrial by-products. As these substances mix and sit together, they begin to break down. If oxygen is limited, bacteria working without oxygen (anaerobic bacteria) take over. The by-products of their activity include gases such as hydrogen sulphide, methane, ammonia and other volatile compounds – and these are what cause the unpleasant odours.
Hydrogen sulphide is one of the most noticeable culprits. It is the gas that smells strongly of rotten eggs and is often released when organic matter such as food scraps or faecal matter decomposes in an oxygen-poor environment. Ammonia, on the other hand, gives off a sharp, pungent smell that is instantly irritating to the nose and eyes. Other gases like methane do not always smell as strongly, but they contribute to the general stench and can also be hazardous.
Common Sources of Wastewater Odours
For ordinary households, smells most often arise from:
- Blocked or dirty drains where food waste accumulates.
- Grease traps or kitchen pipes coated with fats and oils.
- Septic tanks that have not been properly maintained.
- Stagnant water in unused bathroom or kitchen facilities.
On a larger scale, communities and industries face stronger odours from:
- Municipal wastewater treatment plants.
- Food processing facilities where proteins, fats, and sugars are present in high volumes.
- Agricultural sites dealing with animal waste or slurry.
- Industrial sites that generate organic pollutants during production.
Why Traditional Approaches Fall Short
Many people respond to wastewater odours by pouring bleach or chemical cleaners down the drain. While this may create a temporary sense of cleanliness, it does not address the root cause. The organic material that causes the smell remains, and as soon as the chemical effect wears off, the smell returns. Worse still, harsh chemicals can disrupt the natural microbial communities that normally help to break down waste safely. Over time, this can lead to more stubborn odour problems and potential damage to the local ecosystem.
The Consequences of Ignoring Wastewater Odours
Impact on Health
Strong wastewater odours are not merely unpleasant – they can also be a sign of harmful gases being released. Hydrogen sulphide, for instance, is toxic at high concentrations and can cause headaches, nausea, dizziness, and respiratory irritation even at lower levels. Ammonia is another irritant that affects the eyes, nose, and throat. Prolonged exposure in poorly ventilated areas can lead to more serious health issues.
Environmental Damage
If wastewater is allowed to stagnate or is discharged without proper treatment, it carries odorous and harmful compounds into rivers, lakes, and soils. These pollutants reduce oxygen levels in natural water bodies, suffocating fish and aquatic life. They may also encourage the growth of harmful algae, which further depletes oxygen and disrupts ecosystems. The smell is therefore a visible warning sign that something deeper is wrong with the environment.
Community and Social Issues
For communities living near wastewater plants, landfills, or industrial facilities, bad smells can cause significant distress. Residents often complain of nausea, headaches, and reduced quality of life. Odours can also affect property values and discourage local investment. For businesses, a reputation for foul smells can harm customer trust and invite regulatory scrutiny.
Regulatory and Legal Consequences
In many countries, including the UK, strict environmental regulations are in place to protect communities and ecosystems from pollution. Strong odours are often taken as evidence of poor wastewater management. Companies or councils that fail to address these problems may face fines, legal action, or be required to make costly upgrades.
The Solution: Natural Enzyme Remediation
How Enzymes Work
Enzymes are natural proteins that act as catalysts. This means they help speed up chemical reactions without being consumed in the process. In the case of wastewater, different enzymes target specific pollutants:
- Proteases break down proteins into amino acids.
- Lipases break down fats and oils into fatty acids and glycerol.
- Amylases break down starches and carbohydrates into simple sugars.
By breaking down large, complex molecules into smaller, harmless components, enzymes reduce the food supply for odour-producing bacteria. This not only eliminates the source of the smell but also makes the remaining matter easier for natural microbes to digest.
Why Enzymes Are Safer Than Chemicals
Unlike bleach or synthetic deodorisers, enzymes do not introduce new toxins into the environment. They are biodegradable and naturally break down once they have finished their work. This means they leave behind no harmful residues. Because they target specific compounds, enzymes work precisely and efficiently, reducing the need for repeated treatments or heavy chemical use.
Bioglobe’s Bespoke Enzyme Solutions
At Bioglobe, we go a step further than off-the-shelf enzyme products. We analyse the pollutants in our laboratory in Cyprus and then design bespoke enzyme blends that are tailored to each situation. Wastewater problems vary widely: the composition of pollutants in a food processing plant is very different from those in a domestic septic tank or an oil-contaminated river. By creating customised solutions, we maximise the effectiveness of treatment while keeping everything safe and natural.
Applications for Households
For everyday households, enzyme solutions can be used to keep drains, grease traps, and septic tanks clear and odour-free. A small but regular application of enzymes prevents fats and proteins from building up and decomposing into smelly gases. Because the treatment is safe, it poses no risk to children, pets, or garden wildlife.
Applications for Industry
In industrial and municipal contexts, Bioglobe’s enzyme remediation can transform wastewater treatment. Enzymes reduce sludge volumes, lower Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), and restore balance to microbial communities. This not only reduces odours but also improves compliance with environmental regulations. Facilities that adopt enzyme remediation often find that maintenance costs are reduced and efficiency improves.
Applications for the Environment
Enzyme remediation can even be applied directly to polluted rivers, lakes, and soils. By accelerating the breakdown of harmful organic compounds, enzymes help ecosystems recover more quickly. Because enzymes are proteins, they integrate harmlessly into the natural cycles of life, leaving no negative impact behind.

FAQs
Why does sewage smell so strong?
Sewage smells strongly because it contains a high concentration of organic matter such as fats, proteins, and carbohydrates. In oxygen-poor conditions, bacteria break these down into gases such as hydrogen sulphide and ammonia, which have powerful, unpleasant odours. The longer the waste stagnates, the stronger the smell becomes.
Can enzymes neutralise odours?
Yes. Enzymes do not mask smells – they tackle the root cause. By breaking down the organic material that produces the odour, they prevent gases from being released. For example, a lipase enzyme will break down fats into simple components that do not rot and smell. This provides a longer-lasting and safer solution.
Does it work better than chemical deodorisers?
In most cases, yes. Chemical deodorisers may hide smells temporarily, but they rarely address the source of the problem. Enzyme remediation breaks down the pollutants causing the smell, leading to a lasting improvement. It also avoids the harmful side effects that chemicals often bring, such as toxic residues and disruption of natural microbial life.
How to Clean Industrial Wastewater Naturally
Cleaning industrial wastewater naturally involves a multi-step process. First, the pollutants need to be analysed so that the correct enzymes can be selected. Then, bespoke enzyme blends are introduced to break down fats, proteins, and carbohydrates. Aeration and mixing are maintained to ensure healthy microbial activity. Over time, sludge volumes are reduced, odours disappear, and water quality improves. Unlike chemical treatments, this method works in harmony with natural systems, ensuring that the final discharge is safer for the environment.
Conclusion
Bad smells in wastewater are more than just an inconvenience – they are a warning sign that pollutants are breaking down in an unhealthy, unbalanced way. If ignored, they can affect health, damage the environment, harm communities, and even bring legal consequences.
