Bathtubs, sinks, toilets, washing machines, and dish washing 

machines create used water – wastewater.

We must treat the used wastewater. Domestic wastewater 

becomes a problem that must be solved in the best possible way 

yet there are still people believing the best way to get rid of 

wastewater is to let it flow into a concreted bottomless neighboring 

pit or septic tank. This is a crime to your neighbors and nature. 


What can we do with wastewater?

1. Wastewater can be accumulated in underground septic tanks. 

Septic tanks feature various capacities, they should be selected 

according to the volume of wastewater; however if you are 

discharging wastewater into these devices, you must periodically 

hire someone to take away the accumulated wastewater to the 

treatment plant. The frequency of such services depends on the 

volume of wastewater and sewage treatment required.

2. You can install a wastewater treatment or sewage treatment 

plant. There are many models on the market; therefore you must 

be careful in your selection when replacing your septic tank.


Wastewater treatment plants

Technologies are constantly developing, however generally 

wastewater treatment plants can be classified into aerating and 

anaerobic (also called septic systems). Such wastewater treatment 

plants are often used for the treatment of domestic wastewater.

Anaerobic wastewater treatment plants (septic systems) can be 

imagined as the system of “several wells” – wastewater flows from 

one reservoir to another and is gradually filtered. These systems 

do not require power or any maintenance, however the treated 

water does not normally comply with environmental requirements.

Usually such systems require additional cleaning – filtering with 

specially installed soil or plants, or other treatment facilities (e.g. 

filtration well).

Although this plant is based on very simple, even natural methods 

– penetration via soil, using its filtration potential, it usually 

disappoints owners who select this kind of wastewater treatment 

plant. The assembly of a simple system also requires skills and 

knowledge, whereas the self-made equipment usually pollutes the 

soil and ground water.

Another significant disadvantage of such plants is greater area, 

required for installation of septic systems. Sanitary safety zones 

must also be increased from lakes and rivers.

Despite such wastewater treatment plant operates unattended, its 

efficiency cannot be increased in case of increased volume of 

wastewater. Supervision of protection of soil from pollutants is also 

complicated. Constant fermentation, osmosis processes increase 

the likelihood of unpleasant odor.

The lifetime of this wastewater treatment plant is relatively short – 

approximately 5-10 years, after this period you should install a new 

wastewater treatment plant and manage the old one.

Aerated and biological sewage treatment plants cleans the 

wastewater to higher levels. The water resulting from treated 

wastewater can be used repeatedly – it complies with all 

environmental requirements. Such water can be released into the 

soil, open water bodies, or it can be accumulated and used 

repeatedly, e.g. for watering of lawns or carwash. Normally this 

high quality of treated water can only be obtained by wastewater 

treatment plants, certified by notified laboratories, approving the 

requirements for wastewater treatment plants. Air supply is 

required for these plants, ensuring the existence of bacteria 

participating in the wastewater treatment processes; for this 

purpose, electricity is required. Power consumption depends on 

the capacity of the air required. Occasional removal of 

accumulated sludge must also be calculated into operational costs.



Operation of biological wastewater treatment plants

Wastewater is discharged via pipes to the biological treatment 

plant and is treated in a several stages; active fermentation 

processes ensure the treated water is clean again.

1. Wastewater is discharged via pipes to the mesh opening 

(designed to stop mechanical and plastic impurities) and reaches 

the reservoir of the biological treatment plant. Wastewater is 

enriched with organic contaminants, remains of food, grease, as 

well as various chemical impurities – washing powder, various 

cleaners, soap, etc. Water is cleaned in several important stages.

2. In the anaerobic (airless) fermentation zone, deterioration of 

organic matter, e.g. remains of food, is processed.

3. The generated matter mixes with active sludge (where the 

plantation of bacteria is flourished) and reaches the de-nitrification 

zone, where bacteria turn the nitrates into nitrogen gas which is 

released into air (similar reaction happens with phosphorus). 

Kitchen and toilet wastewater are also enriched with nitrates.

4. Then follows the aeration zone, where wastewater is saturated 

with air using an air compressor. In this zone, chemical 

dissociation – nitrification is performed.

5. Subsequently the treated effluent outflows via a funnel-shaped 

opening into the bottom of sump, passing the layer of compressed 

sludge and discharging from the plant.

The treated water can be accumulated and re-used for watering of 

lawns, flowers, carwash, or it can be outlet into reclamation trench, 


We must ensure the water outlet into the environment is properly 

cleaned and complies with all environmental requirements. This 

can only be guaranteed with certified biological plants certified with 

CE conformity or similar authority worldwide.



Variety and comparison of wastewater 

treatment systems Part II


A decision to install a biological wastewater treatment plant often 

raises various questions. 


Choosing biological wastewater treatment plant, which 

answers your needs best

The average wastewater treatment plants look the same. However 

they differ in treatment technologies, cleaning parameters, as well 

as in size, shape of plants, installation methods and operational 

costs. Therefore be careful when choosing the wastewater 

treatment plant, assess the abovementioned differences and 

certificates of potential suppliers.

Selecting the right size treatment plant is also extremely important. 

The size of the plant is calculated according to the number of 

residents in the house. The more water we use, the more 

wastewater needs to be treated. Smaller wastewater treatment 

plants are suitable for families living in individual houses, whereas 

larger plants are suitable for hotels, campsites, restaurants, etc.

You build a house, expecting it to serve you a lifetime; therefore 

you should select the wastewater treatment plant with the 

appropriate responsibility. If you have difficulties in calculating the 

need for wastewater treatment yourselves, ask for the assistance 

of skilled specialists. Do not make a mistake, selecting a smaller 

wastewater treatment plant just because it is cheaper. In some 

time, all problems and expenses may outweigh the “saved” costs.



When is the right time to mount biological wastewater 

treatment plant?

Consider the wastewater treatment plant as soon as you purchase 

the site. In designing the house of your dreams, do not forget to 

determine the location for wastewater treatment system. You must 

plan the appropriate location, respecting the requirements for 

statutory sanitary zones.

The treatment plant can be installed during the construction stage 

of the house, however major external construction of the house 

(walls, roofing) must be finished, ensuring no heavy-weight 

machinery, such as trucks, lifting cranes, delivering various 

constructing materials and facilitating the construction process, is 

required to enter into the site. Such heavy-weighted machinery can 

damage the laid pipework or the installed plant.

Compact treatment plants are small in size and do not spoil the 

view, however operate in a perfect manner.


Who could install biological wastewater treatment plant?

The efficiency of the plant is closely related with correct 

installation, therefore this task should be trusted to skilled 

specialists, or it should be performed closely observing their 

instructions. If you have any doubts in your capability, do not 

hesitate to contact the appropriate specialists.

Specialists will install the plant in one day. Starting with the very 

first day, the treated wastewater complies with all environmental 


It is most convenient to select the wastewater treatment plant from 

a company that produces, installs the plants and ensures their 

warranty and post-warranty maintenance. Such companies often 

provide the plant designing and consultation services, therefore all 

required topics can be arranged in site, thus saving both time and 



How should I start using biological wastewater treatment 


Biological wastewater treatment plants feature one major 

advantage – the commissioning of such plants is extremely simple. 

The installed wastewater treatment plants can be launched for 

operation on the same day, after delivery and pouring of active 

sludge and all adjustment proceedings. No further special 

procedures are required; the only important thing to do is to ensure 

wastewater starts flowing into the treatment system.

Another important advantage of such wastewater treatment plants 

is the capability of plant to stay free of wastewater for a prolonged 

period, even one month. It is very convenient during vocations or 

when installing wastewater treatment plants with discontinuous 

flow of wastewater, e.g. in rural tourism homesteads.


Maintenance of biological wastewater treatment plants

The use of biological wastewater treatment plants is convenient 

and nearly maintenance-free. Special technologies of these 

systems ensure proper management of even great volumes 

accessing into the system, e.g. full bathtub of soapy water. With 

these wastewater treatment plants, you can also use convenient 

domestic chemicals, as they do not worsen the efficiency of the 

system operation.

Efficiency of system operation is also not affected by toilet paper or 

kitchen wastewater, accessing into the system, as the biological 

plant manages this kind of matter.

This equipment is also resistant to winter colds, as the sewerage is 

supplied with warm air flow; various biological processes also 

ensure cold resistance in the system.



Biological wastewater treatment systems feature extreme 

durability. They are usually guaranteed over 10 yearlong problem-

free operations. However by purchasing equipment of such high 

importance, we want a lifetime operation.
