Biological wastewater treatment plant range for up to 50 persons

To whom our biological wastewater treatment plants are recommended and why??

Using a wastewater treatment plant, after a single investment you will no longer need to worry about continuously increasing sewerage utility costs, and water utility costs.

Further more, with the recycling of water, you can reduce wastage, thus the impact on the environment.
Therefore we recommend our biological wastewater treatment plants to all those who wish to reduce overhead costs and who are environmentally conscious and plan ahead long-term!

Among a variety of reasons, THIS IS WHY IT IS WORTH CHOOSING OUR WASTEWATER TREATMENT SYSTEMS:

we use an individually developed sludge dewatering bag technology in our plants, so you will never need sewage suction
our products bare the CE certificate
products are manufactured at our plant site in the city of Esztergom, Hungary.

The purification efficiency of biological wastewater treatment plants exceeds the required limit values
(refer to the “Technology and Technical Specification” menu).

1. Private homes

Realization of self-supporting, biological wastewater treatment is done most easily in case of private homes. Water recycling can also be implemented simply at low cost; and purified water can be used for irrigation of the garden. The plant is capable of handling load fluctuations within a wide range, thus several days or weeks of holidays, or frequent guest visits won’t be a problem either, as these can be by-passed with the fitting of a microprocessor control unit. Due to the low space requirement of equipment, and accessories such as manhole covers covered with artificial grass, the plants are almost invisible in any garden. ÖkoTech-Home Kft. has references for private home plants throughout Hungary.

2. Holiday and weekend houses

Fluctuations in load are often significant in case of these property types. Most people don’t use their holiday houses at all during the winter, while they are used continuously or as a permanent residence from spring to autumn. Fitting of a microprocessor control unit to by-pass smaller, few days or weeks of fluctuations is also advisable in case of holiday houses, but the several months’ long winter shutdown requires an entirely different solution. The wastewater treatment plant has to be prepared for the winter, it has to be sucked out then filled up with clean water. The plant has to be restarted before next use; ÖkoTech-Home Kft. can be assigned to carry out this process. We have installed plants for several weekend and holiday houses throughout the country.

3. Inns, Motels

Biological wastewater treatment is a good investment in case of catering businesses as well, either considering the exchange of using the sewerage network, or the savings resulting from recycling water. Due to their nature of use, load fluctuations can be extremely strong in case of these facilities, as many of these only receive guests on a seasonal basis. In such cases, the installation of two smaller wastewater treatment plants can be a solution. This way, when load is low, only one plant would be operating, and when it is higher, the second plant can also be started, allowing a wide range of capacity settings. Independent, biological wastewater treatment is also recommended for inns, motels, that wish to provide their guests accommodation suited for ecotourism. Several smaller inns utilize the biological wastewater treatment system of ÖkoTech-Home Kft.

4. Hunters Lodge

The loads of such facilities – similarly to that of holiday houses – also heavily fluctuates, but this would not represent a problem with the microprocessor control unit available as an accessory, and with the winter preparation already described for weekend and holiday houses. A further advantage of the plant is that it complies with all environmental protection requirements and regulations, thus it can also be installed in protected areas after obtaining the necessary permits. We have several hunters lodge references.

5. Condominiums

Just as for private homes, biological wastewater treatment plants can also be used for condominiums, and in this case, load fluctuations will also have a lesser effect.

6. Plant Sites, Offices, Workplaces

Biological wastewater treatment is commonly used for these types of facilities as well, and water can be recycled for the irrigation of areas around the plant site. It must be noted, that our equipment is designed to purify communal wastewater. In case of a need to purify other, industrial, process technology related wastewater, pre-treatment and alternative solutions must be first discussed. Numerous plant sites utilize wastewater treatment systems installed by ÖkoTech-Home Kft.

7. Farm-steads

In case of farm-steads in distant locations without a central sewerage network, instead of the commonly used sumps, or other not quite environmentally friendly methods, biological wastewater treatment can be a clean and cheap solution. Purified water can be utilized in this case as well, for example for irrigation. The electricity demand of the plant is minimal, so it can be supplied by means of solar cells, a wind turbine, or other alternative technologies. In relation to farm-steads there is often an opportunity to apply for subsidy. Please contact us, in case of interest in such solutions.

8. Groups of houses, common wastewater treatment of streets

Several houses, facilities, or even an entire street can be connected to a common system. In this case a smaller scale local sewer network does have to be constructed, but in case of these smaller systems, problems due to ground elevation area easier to avoid, just as the need for intermediate sewage pumps.

What happens with the purified water?

With the help of our biological wastewater treatment plants, communal wastewater can be utilized in multiple ways after purification. The most practical method of reuse is the root irrigation of plants.

Where an existing concrete sump is exchanged, the sump can be used as a reservoir for purified water, to allow a better management of amounts of water. If not reused in any way, water can be desiccated in a gravel bed, or be filled into live waters with a water rights permit.

Theory of plant operation:

The biological wastewater treatment plant applies a technology based on biological purification of activated sludge.
When the wastewater produced by the building (kitchen, bathroom) arrives to the treatment plant installed outside, the contaminants contained in the water degrade through anaerobic and aerobic biological processes with the help of activated sludge.

As a result of the chamber system design, the wastewater flowing into the system has a predetermined route. Water is purified by means of a predetermined flow of wastewater from each zone to other zones. The resulting sludge is partially recirculated. The amount of excess sludge produced is minimal, less than in case of other, similar technologies.

Continuous biological degradation is ensured by the compressed air blown into the system by a compressor, which is a system component. The compressor is the only mechanical (power) component in the entire biological wastewater treatment plant.

Wastewater is purified through the above process without the need for any special intervention from the outside. The biological wastewater treatment plant operates without any smells and in almost complete silence, it uses a minimum amount of electricity, with 50W for a plant designed for 2-6 persons.

Economical calculation based on a comparison of our biological wastewater treatment plant and a sump (based on Hungarian conditions, in Euro currency)

Advantages of the biological wastewater treatment plant can be easily utilized. All of the domestic scale, biological wastewater treatment plants sold by our company have the following characteristics:

The plant provides a solution, that is equivalent to the sewage treatment performed by utility providers.
Simple installation and operation. Installation and assembly only takes a couple of hours, and operation can be learned by anyone.
Low investment and maintenance cost. The cost of manufacturing and commissioning of the wastewater treatment plant does not exceed the average cost of connection to a central sewerage network.
In the course of degradation of wastewater, only a very low amount of solid material – stabilized sludge – is produced. For example in case of 4 people, an annual amount of 0.5 m3 (!).
Operation of the wastewater treatment plant is silent, making it also suitable for installation indoors, without the need for additional acoustic insulation.
While installation is effortless owing to the polypropylene material, the biological wastewater treatment plant is also extremely resistant to environmental effects, providing a rather long useful life.
There is little chance for malfunctions.
The biological wastewater treatment plant does not contain any materials, which are harmful to the environment, and it operates without the use of any additive materials.
Low operating costs – the electricity consumption of a domestic-scale plant is between 14-16 kWh a month.
Biologically purified water can be used for root irrigation or other purposes; there are no sewerage utility fees, thus the investment is returned within one or two years.
Requires a minimum amount of maintenance.

About the use of detergents, chemicals

Biological wastewater treatment plants are frequently referred to as “living machinery”, as the digestion of contaminants is done by bacteria and other micro-organisms. These organisms establish a balance inside the plant, they grow and die, but their quantities can be considered constant as a result of a relatively stable system load.

Detergents and other chemical agents used in a household for cleaning, personal hygiene and other duties can be damaging to the bacteria culture, but with a little care, loss of the biological balance, thus the stalling of the system can be avoided.

Materials containing chlorine, strong disinfectants and antibacterial agents are the greatest danger. Such are Clorox, toilet disinfectants, hand disinfectants and antibiotics. The use of these bactericides should be avoided!

A common characteristic of the above mentioned agents and all other synthetically produced cleaning agents is that they contain chemical compounds, which do not, or only slowly degrade when let into the environment. In case of desiccation, or use of purified water for irrigation, these get into the soil, while in case of filling into live waters, they get into water streams and rivers.

For this reason we recommend the use of biodegradable detergents. Active agents contained in degradable detergents, those which perform the cleaning effect are not produced with synthetic processes but with the use of natural acids, enzymes, glycoside (saponin), which entirely decompose in the environment. A perfect example for this is washnuts. This is made from the dried shell of a fruit from India, available in stores and markets. For washing clothes place 4-5 nutshells into the canvas bag supplied with the washnuts and use this as an alternative to washing powders or liquids. A soap like material is released from the nutshells in water, which works the same way as washing agents. Furthermore, each nutshell can be used 2-3 times before they are “depleted”. After use they can be placed into a composter or trash bin. It does not remove heavy stains but it is perfect for the daily washing of clothes.

Another handy solution is the use of washing soda, lemon juice, sodium bicarbonate or vinegar for various cleaning purposes. Factory made detergents are also available, which protect both the balance of the treatment plant and the environment. Such brands are Frosch, Ecover, Naturzone, and others available in bio-stores, or biodegradable cleaning agents from various sources.

Overuse of chemicals or other agents, which are damaging to the bacterial flora, cause the micro-organisms to die out. In this case the plant has to be started up again to be functional.

In case you have any further questions regarding the use of detergents, please contact us at any of our availabilities!

An average installation process from conception to realization:

Installation of the domestic, biological wastewater treatment plant, the required accessories, the method of installation depends on customer requirements, ideas, site conditions and applicable regulations, etc. Accordingly, all aspects have to be discussed before the installation of a plant.
