Wastewater treatment plants are complex systems that convert wastewater into liquids that are safe to discharge or reuse. For them to work efficiently and last long, in addition to quality design and installation it is important to use the right products, both for maintaining the biological processes and for looking after the pipes and equipment.

In this article we will explain what types of products are used with wastewater treatment plants, how they work and which are the most suitable for different situations, including specific products from ERMAX BG that you can find and use with your installation.

1. Why are products needed for a wastewater treatment plant?

Wastewater treatment plants treat wastewater through biological and mechanical processes. The microorganisms that break down organic substances are sensitive to the conditions in the system, such as pH, availability of nutrients and concentration of pollutants.

Without adding products that maintain the biological balance, the following may occur:

build-up of sludge and grease;
increased odours;
blockage of pipes and channels;
reduced treatment efficiency.

That is why, in the regular operation of the wastewater treatment plant, it is important to know in which cases and which products to use.

2. Biological products for maintaining wastewater treatment plants

What they are

Biological products contain microorganisms and enzymes that speed up and support the breakdown of organic substances in wastewater. They:

improve the breakdown of grease, proteins, starch and toilet paper;
reduce the amount of sludge;
limit unpleasant odours;
maintain stable biological activity.

Recommended product from ERMAX BG

Biological product for cleaning septic tanks – a powder product made up of microorganisms, enzymes and nutrient components, designed to support biological breakdown in septic tanks, sewerage systems and wastewater treatment plants.

How it works:

breaks down organic sludge and grease;
reduces foam and sludge;
restores the normal operation of the system.

It is an environmentally clean product that contains no hazardous chemicals, soda or acids and is suitable for regular use as part of the routine maintenance of your wastewater treatment plant.

How and when to use biological products

Routine prevention:

Periodic addition of products maintains optimal biological activity, especially in plants with low load or seasonal sites.

After a period of inactivity:

When the system has not been operating for a long time (for example holiday properties out of season), bioproducts help restore the microflora before active use.

In case of odours and slowed treatment:

If the plant begins to give off unpleasant odours or its efficiency decreases, adding a bioproduct can help to quickly restore the normal process.

3. Products against grease and deposits

Why they are needed

Grease and fatty deposits are among the most common causes of pipe blockages and reduced treatment efficiency. In addition to the biological products we have discussed, degreasers or bioproducts that speed up the breakdown of grease are also often used, especially in:

kitchens and catering establishments;
homes with high consumption of fatty foods;
sites with frequent grease waste.

These products are not mandatory for every plant, but they significantly help its maintenance and prevent blockage problems.

4. Other types of products and additives

Flocculants and settling agents

They help to collect fine particles and sludge, but they must be used carefully and according to the specification of the system.

It is important to avoid strong chemicals, such as chlorine bleaches or acids, which can disrupt the biological balance in the wastewater treatment plant and damage the microorganisms.

5. How to choose a suitable product

When choosing a product for your wastewater treatment plant, keep the following criteria in mind:

Compatibility with the biological system

Choose products that complement the action of the microorganisms or contain them themselves, so as not to disturb the processes in the plant.

Environmental safety

Look for products that are biodegradable and contain no aggressive chemicals. This is in the interest of both the environment and the system itself.

Type and load of the installation

For large plants or those with more grease, a combined use of bioproducts and degreasers may be required.

Type of product	What it does	When it is used	Example ERMAX BG product
Biological products	Help break down organic sludge and grease, stimulate beneficial microorganisms	Routine maintenance, odours, reduced plant efficiency	Biological product for cleaning septic tanks and wastewater systems
Products for grease and deposits	Break down grease and prevent blockages in the pipes	At sites with a kitchen, restaurant, frequent greasy waste	Bioproducts – enzymes and microorganisms
Supporting biological additives (tablets / activators)	Help maintain constant biological activity in the system	Maintenance between preventive services	Bioproducts – enzymes and microorganisms
Flocculants and settling agents	Collect fine particles and aid settling	For heavily polluted water or high sludge	Specialised additives (per project)
Chemical flushing agents	Aggressive cleaning of pipes	Only for serious blockages, with caution	Not recommended for biological systems

6. Tips for effective use

Read the manufacturer's instructions for dosage and frequency of use.
Use the products in combination with regular maintenance (preventive servicing, cleaning).
In case of blockage or odour problems, first try biological products before strong chemicals.

Conclusion

Maintaining a wastewater treatment plant does not end after installation: the correct use of biological products and additives is key to the efficiency, long life and trouble-free operation of the installation.

ERMAX BG has a specialised biological product for cleaning septic tanks and wastewater systems, which can become part of the routine care of your wastewater treatment plant and ensure cleaner, more efficient and more trouble-free operation.
