Septic Tank Upgrades

The ClearFox Nature is a perfect solution for upgrading an existing septic tank. The Bioreactor tank can be installed after an existing septic tank. The outlet of the existing septic tank is simply connected into the ClearFox Nature reactor tank, and the outlet of the ClearFox Nature is then connected to an existing soakaway or stream/watercourse.

If you want to upgrade your septic tank to produce a better quality effluent, the Clearfox Nature is an ideal solution. Simple and easy to install, without the need to bring a power supply to the tank location. Adding the bioreactor tank after your septic tank gives you a system that is totally compliant with EN12566-7.

The Clearfox nature non-electric sewage system

How Does the Clearfox Nature Non Electric Sewage Treatment Plant Work?

Primary Treatment

Raw sewage enters the first tank which is the primary chamber. Here, any large solids settle out of the wastewater. These solids settle into the bottom of the primary tank to form settled sludge. this sludge settles and compacts, allowing for long desludging intervals.

Any fats, oils, grease or scum floats on the top of the water column in the primary chamber. This material forms a scum layer. The primary tank is an anoxic, passive treatment step. As all floating material and all solids are retained in the primary chamber, the wastewater that flows forward is cleaned in this primary treatment stage.

The Bioreactor

Primary cleaned wastewater flows by gravity into the reactor chamber. A tipping plate spreads the effluent evenly over the entire media surface. The plastic media in the bioreactor has a very high surface area. This surface area is colonised by naturally occurring bacteria. These bacteria feed on the nutrients and organic material in the incoming wastewater, cleaning it to a very high standard.

Aeration

Electric systems use small electrical air compressors to aerate the wastewater and to provide the bacteria that complete the cleaning with oxygen. However, the Clearfox Nature uses natural ventilation via a small 1m high vent stack to draw fresh air into the tank. This means the system does not need any electricity. So you have a process driven by naturally occurring bacteria, using natural ventilation for the aeration process. This makes the Clearfox Nature a totally sustainable method of wastewater treatment. Saving you money on operational costs every day.

  1. Rated 5 out of 5

    Not cheap but I wanted non electric. Very few options. I did my research and realised the all the other the non electric plants need replacement parts and good bit of maintenance. So in the end it was a simple decision going for the clear fox nature.

  2. Rated 5 out of 5

    Not building a passive house – but like the idea of non electric. Nice slope on my site so was a perfect fit. Installed now a few weeks and its working like a dream. You would not know there was a system installed as totally silent and no smell.

  3. Rated 5 out of 5

    Installed at our holiday home. Excellent choice as it is not guzzling electricity while we are not there [like other systems] and we have no concerns over arriving to the house after being away for 3 months and something being broken as no moving parts.

  4. Rated 5 out of 5

    Installed a 32 pop system for my glamping site. Was the logical choice. Very happy.

  5. Rated 4 out of 5

    My installer loved the unit. Only issue is we needed manhole extensions as was a deep installation and there was a small extra charge for them. Not really a complaint and was more a mistake by my installer really. Would recommend the nature unit for anyone who wants the best.

  6. Rated 5 out of 5

    Super unit. Installed it myself over a weekend to replace a very very dodgy existing septic tank.

  7. Rated 5 out of 5

    Not cheap but I wanted the best. A1 unit. If I ever build again I will get my builder to install another.

  8. Rated 5 out of 5

    Recommended by my architect. I am pleased with the choice I made.

  9. Rated 5 out of 5

    Installed for an upgrade at my house. There was no electricity in the only available location for the tank, and bringing a power supply to the tank would have cost a fortune. So while I didnt have much choice in going for non electric – I am ultimately happy with the service I got.

  10. Rated 5 out of 5

    Just what I have been looking for. 5+++

  11. Rated 5 out of 5

    My name should describe the type of person I am. This was the ONLY option for me.

  12. Rated 5 out of 5

    Installed one for my holiday home. Wont be using energy in my absence. Very pleased with the end result.

  13. Rated 5 out of 5

    A bit more expensive than a regular system, but I really wanted a non electric system. When you compare the nature unit to the other couple of non electric plants on the market it is really a simple choice.

  14. Rated 5 out of 5

    Got an 8 person unit. Not cheap but very very satisfied with it.

  15. Rated 5 out of 5

    I build high end homes. This is my third unit installed. A very high quality product and they are guaranteed to be trouble free. A no brainer if budget allows you to put one in.

  16. Rated 5 out of 5

    Purchased 5 of these for a cluster of houses I am building. Great product. Not cheap but no need to bring a power supply to the unit or do electrical works, etc. I just want total security and trouble free operation.
