Choosing the right Biotoilet model. Which of the Biotoilet models is suitable for our use? The choice of model is affected by the use of the device. All Biotoilet models are  designed for the needs of one family (approx. 5 people) - their emptying method and interval do vary. Smaller ones are emptied more often (60 uses) than larger ones 200 to 2000 uses). Smaller models are intended as a “second toilet” for indoor use or other small-scale use, larger models as “main toilet” for holiday homes and detached houses for residential use. When the utilization rate is higher, the capacity can be increased with additional trolleys / containers.

Frequently asked questions.

Questions                                                        

How do you proceed with the planning to install an AQ Bio? Do I need an official permit? Can I install the system myself? Can I get planning / construction help? We offer a free remote mapping. In connection with the categorization, you will receive written information about which AQ Bio system is suitable for your use, and if official permission is required. If you need / want to renew the property's sewage treatment, it is also included. The project can be carried out in whole or in part by yourself. Through us, in addition to the mapping and planning, you can also get help with installation, See RaitaPro page. See RaitaPro- page.
Environmental friendliness. How environmentally friendly is AQ Bio? AQ Bio is a very environmentally friendly toilet choice. It can handle most household wastewater load (WC 90% nitrogen, 80% phosphorus and 60% organic material) - the rest is in washing and rinsing water ( greywater),  which are purified in an NP unit and a greywater treatment systemt equipped with precipitaion well (sedimentation well). See AQ Bio / NP cleaning efficiency.   The energy requirement is very small. Waste is recycled at the source (no need for emptying / transport infra). Long service life 50-100 years). Material recyclable. Given these, the carbon footprint is for AQ Bion very small (a fraction of the toilet system's carbon footprint).
Take care of and maintain your AQ Bio. Is it hard? What needs to be done? Measures related to normal use, ie adding compost litter and leveling compost about once a week, are not time consuming or laborious. Emptying, changing of trolley / container (2 - 12 month interval) has been done easily on our models. It usually takes 15 min to 30 min time. The equipment is simple in technology and does not require regular service. We help to technically plan easy care and maintenance. See RaitaPro- page. See Manuals on the technical pages .  
Acquisition and operating costs. What does the purchase cost - what does the use cost? Getting a AQBio is more economic than getting a wc / closed tank / sewageconnection. Operating costs (RAKE chemical and compost litter) are also low because waste can be easily composted and recycled on site. Book a time for free remote mapping- we are happy to help you in planning. See RaitaPro- page. See Manuals on the technical pages .   
Winter use - measures for the cold season. Thermal insulation, heating? Measures after the summer season (summer cottage)? If the property is used in winter, it must be taken into account during installation by isolating the system and / or equipping it with a heating element. If used only in the summer, AQ Bio can be uninsulated . NP unit, toilet seat and piping must be protected from freezing (or emptied for the winter).

Smell. Does the use of the toilet cause odors in the room or in the environment? NO. Book a time for free remote mapping- we are happy to help you in planning. See RaitaPro- page. See Manuals on the technical pages .   
Hygiene. Are AQ Bio hygienic in use and when emptying? When used, AQ Bio corresponds to WC - hygiene level. Use safety equipment when emptying - e.g. gloves. A well-finished compost does not contain harmful bacteria or viruses and its handling is not dangerous when using safety equipment.  Book an appointment for free remote mappingon the  RaitaPro- page. - we will help to dimension the system. See Manuals on the technical pages .    
Bidet shower. Can I use the bidet? A bidet shower can be used. Book an appointment for free remote mappingon the  RaitaPro- page. - we will help to dimension the system. See Manuals on the technical pages .  
Placement of seats / other technology. Max number of seats. Does the toilet seat have  to be directly above the compost bin? How many toilet seats can be connected to Aq Bio? No, the toilet seat or several seats can be placed freely. Up to 3 seats can be in the system, Maximum distance from the separator unit is 20 m. Book an appointment for free remote mappingon the  RaitaPro- page. - we will help to dimension the system. See Manuals on the technical pages .  
The wash and rinse water drain is higher than the Aq Bio system. What can be done? Where can the NP unit be placed? After the separator unit, the water can be pumped higher to the drain. The NP unit  can be placed indoors or outdoors. Book an appointment for free remote mappingon the  RaitaPro- page. - we will help to dimension the system. See Manuals on the technical pages .
