Clarity Biofilter



What is a biofilter?
Clarity biofilters use the most advanced biological filtering technology on the market. This revolutionary system works by aerating wastewater from the home using naturally occurring bacteria and organisms that degrade, oxidize and consume contaminants while performing primary, secondary and tertiary cleaning of the effluent before it enters your yard.


What are the advantages of a Clarity Biofilter?
There are lots of advantages of a Clarity Boifilter over other septic systems. Firstly, the system is naturally cleaner because it uses advanced aerating technology to produce an effluent that exceeds approved levels. And because Clarity biofilters generate a much purer effluent than other septic systems, they don't need a large, conventional leach field which means no costly excavations or clear cutting. Plus there are no nasty odours and no risk of leach field failures, which can cause a lot of damage to your property and are costly and unpleasant to clean up.


How much does a Clarity biofilter cost?
The cost depends on the size of the home and number of bedrooms. Each project is different and there are a number of site specific factors which will affect the type of biofilter needed including soil conditions, height of groundwater table and bedrock, site access, size of property, number of people using the system and conditions of installation (e.g. if excavation or clear cutting is required). All of these will affect the price so for the most accurate quote, please contact us.


Where is the Clarity Biofilter approved?
The Clarity Biofilter is approved for residential applications across Newfoundland and Labrador. We have also begun testing the system further afield so Clarity biofilters may be available in your area soon. If you are interested in installing a Clarity Biofilter outside of Newfoundland and Labrador, please contact us to discuss your requirements.


Can I use a Clarity Biofilter to replace my old system?
Yes. Clarity biofilters can be retrofitted into most septic systems. See our biofilter retrofitting page for more details.


Will it smell?
No. Clarity biofilters are specifically designed to be odour-free.

Biofilter vs Septic Tank



Should I get a biofilter or a septic tank?
The biofilter replaces your septic tank but can work in conjunction with your current system. Clarity biofilters are approved as a standard system for onsite wastewater treatment and are suitable for most applications. However, if you're unsure whether the product will be suitable for your property, our professional, government-approved designers will be happy to advise you.


Is a biofilter more expensive than a septic tank?
Biofilters can initially cost more than a conventional septic tank. However, their superior reliability and low maintenance costs make them much more cost effective in the long term. Also, because they don't require a large leach field, they are more compact meaning reduced costs for clear cutting and excavation.





Design and Installation



Will I need a septic design?
In Newfoundland and Labrador, all new builds and developments require a government-approved septic design. Clarity include this in our system price to ensure that your system is in line with all government standards.


Can I design/install my own septic system?
No. Under the Approved Designer policy of Service NL and Dept of Health and Community Services, the initial inspection of a building lot with proposed on-site sewage services must be carried out by a Government Service Centre Approved Designer. Our Clarity and Service NL approved designers are fully trained in septic design and are able to design solutions to suit virtually any lot.


What is the area required for a Clarity Biofilter?
Clarity Biofilters have one of the smallest footprints in the industry (up to 75% smaller than a conventional septic system) as they don't require a large leach field. The actual size depends on a number of factors including the size of the property, frequency of use and soil conditions. For more information on the size of biofilter required for your property please contact us.





Maintenance and Aftercare



Do I require a maintenance contract?
We would highly recommend regular maintenance and annual servicing for your Clarity biofilter to ensure it continues to operate effectively and to prolong its running life. We offer a servicing package for all of our customers but you have the choice to avail of the service or not.


How often do biofilters and septic tanks need to be emptied?
Because Clarity's biofilters process and breakdown the wastewater far more effectively than a septic tank, they need desludging approx every 2-4 years - far less frequently than a septic tank. Exact frequency of desludging will depend on daily flow and property conditions.


What causes a septic system to fail?
There are a number of reasons why septic systems fail including clogged pipes, burnt out pumps and plugged filters. However, one of the most common causes of septic system failure is a decreasing absorption rate of the soil. Most traditional septic systems require an leach field to distribute the wastewater into the soil. As you can imagine, the wastewater that comes through a septic system is full of bacteria and over time this can plug pores in the soil so it can no longer absorb the water. At this point it is usually necessary to dig up and replace your septic system (plus a large area of your garden). Clarity biofilters do not suffer from this issue as the water going into the diffuser exceeds approved levels and is therefore easily dispersed into the soil.


What do I do if I think my system has failed?
We suggest you call Clarity immediately. Septic system failures can cause serious damage to your home and garden so it is important to get a new system put in place as quickly as possible.


Are garburators ok?
Garburators and septic systems generally do not mix and if a competitor has suggested to you that their system is garburator-friendly, you should think twice about using them. Although some systems may be able to just about cope with the huge amount of extra organic matter this will add, the system will wear out much more quickly and you could end up with a messy and costly system failure on your hands.


Should I use additives in my biofilter?
Clarity Biofilters do not require additives. The system uses natural processes to clean and filter wastewater to an exceptionally high standard and therefore does not need any sort of chemical help.


What happens in the event of a power outage?
Should a power outage occur the system will stop for the time the power is off. The system will reboot once power is restored and start working again.


Could a power interruption result in system malfunction?
Most of our units are gravity flow but if the biofilter has a pump to take the effluent upslope and the power goes out, the backwater valve will protect the unit and prevent a malfunction. The system will then reboot when the power is restored.


How does future system maintenance work?
Clarity will do a free inspection of the tank after commissioning. Usually about 90-120 days of use to ensure its proper operation and flow levels. We recommend homeowners sign up to our peace of mind servicing package.


Could a general contractor make sense of the system and perform maintenance work on the inner workings of the tank?
It is not difficult for a decent general contractor or experienced electrician and or plumber to carry out routine maintenance. Some people choose to opt out of the servicing package because they are in similar vocations and would prefer to maintain the system themselves as they find it quite straight forward. However, you should be aware that work carried out by anyone other than a Clarity approved engineer could invalidate your warranty.


Can replacement parts and spares be easily obtained at a hardware store?
We carry all parts and stock to carry out repairs and servicing. Parts can also be sourced locally and are easy to find from various companies. However, we recommend that you use a Clarity approved installer to carry out repairs as this will ensure that your warranty is not invalidated.

Is there a warranty on the biofilters?


Yes. All our biofilters come with a 10 year warranty covering the casing and the biofilter media. The pump, floats and alarm are also covered under a 5 year warranty. Unlike some competitor products our fibreglass tanks do not rust meaning that, with normal use and proper maintenance a biofilter can be expected to last for at least 20 years.


Jargon Buster


Biofilter

A bed of media on which microorganisms attach and grow to form a biological layer called biofilm where the treatment occurs, mostly by biodegradation.

Biofilter Media

The plastic media inside Clarity biofilters is designed to have the largest possible surface area. This means there is more opportunity for microorganisms (bacteria, fungi, yeast etc), macroorganisms (protozoa, worms, insect lavae etc) and extracellular polymeric substances (EPS) to develop inside the system and form the biofilm where the treatment occurs.

Absorption Field / Leach Field

A series of perforated pipes laid in a bed of crushed stone, filters and distributes the effluent throughout the field by allowing the effluent to slowly trickle from the perforated pipe into the crushed stone and down through the soil. The crushed stone and soil act as biological filters.

Septic Design

For every new development, you must submit a Septic Design from a government-approved designer (following a site evaluation) to the local Government Service Centre. This will include a detailed sewage disposal system design and water supply design (signed by the designer), a completed application (signed by the applicant), and Municipal Approval (in a letter from the
municipality).
