How does the Biocell Bioclean home sewage treatment plant work?

Bioclean sewage treatment process diagram

The Biocell Bioclean is a complete packaged sewage treatment plant. The full treatment process happens within a single compact tank. The treatment process is quick, simple and trouble free. It operates quietly and without odour to achieve high treatment standards.

  1. Raw sewage from the house flows into the sewage treatment plant. The integrated filter retains any non-biodegradable items.  Coarse bubbles break down solids in the filter, thereby reducing the need for a large primary chamber.
  2. Primary treated wastewater then flows into the anoxic zone. In this chamber, activated sludge mixes with the incoming wastewater starting off the treatment process. Any remaining solids settle out here.
  3. The small air blower then activates and runs, aerating the wastewater via the bubble diffusers in the next chamber of the tank. This serves to mix and to totally aerate the wastewater. Naturally occurring bacteria develop in the aerated wastewater. They feed on the organic material and nutrients in the sewage, totally treating and cleaning it of contaminants. The aeration process supplies the bacteria with abundant oxygen, allowing them to multiply and clean to industry leading standards.
  4. The settlement phase occurs after the aeration and cleaning has happened. During the settlement phase, any remaining fine solids in the wastewater settle to the very bottom of the tank producing sludge which flows back to the primary chamber. The water in the final chamber is totally clean and ready for discharge to the soakaway or stream/watercourse.

  1. Herman Greene

    In the USA and in small lot community with body of water, 58 thousand acre lake. I was searching for a treatment in small lot restricted to no septic. The lot is 4000 square ft. The body of water is less than 150 feet.

  2. HABIB

    hi. i emailed many times but have not received any response. can any one tell me the price for a family about 5?

    • James Clarke

      Hi Habib, please email your query to Kind Regards, James.

  3. A Clarke

    Shopped around to find a good value solution for our site that was also fairly easy to install. The Bioclean fit the bill in both cases. This is the 3rd treatment plant we have installed on the site and it was by far the best quality and easiest to install. It has been running now for 6 months and we are very happy with the performance. Thoroughly recommend!

  4. Ronnie O’Callaghan

    Seriously good value. glad I found them as very limited budget at the end of the build. Installed now for 2 weeks and working great.

  5. fred Wurth

    Spent alot of time researching units. I am price sensitive. This was unbeatable value and its actually a great product.

  6. Toby Williamson

    Insane value. 5+++

  7. JJ Roarke

    Seriously good value. Saved a few hundred pounds. Happy customer here!

  8. Brian Sankar

    Great value. Was over 250 pounds lower in cost than other systems. When it arrived both me and my installer really were impressed. Its a low cost tank but great quality.

  9. Fred Winston

    A friend installed one 2 months ago and recommended them. Glad I took their advice.

  10. Frank Edmunds

    A great product for the price.

  11. Dave Bradley

    Serious value for such quality. Delivered in 3 days to remote part of Scotland too!

  12. John Doak

    Did my research, and at the end of the day it seems all sewage treatment plants are basically the same. You have a tank with internal chambers and an air blower to power the process. No difference between the bioclean and a tank for 500 quid more. Not even a better standard of cleaning from the more expensive tanks. Dont be fooled. My only worry was the quality – but when you see the tank after delivery you will see its a highly engineered product.

  13. Mr. Dawson

    Put one in for a customer as part of a new build. They were happy and so was I with the saving. Very strong tank.

  14. Davy Building

    I use these systems as they are great value and I have not had a callback from a customer yet.

  15. Sean Wilson

    Have one installed a while. Very close to the back door. Bought it on the basis that they are odour free. And based on my unit that is 100% true – no smell at all.

  16. Septic Systems Ireland

    We install a variety of systems but going forward I will be going for Biocell Bioclean units all the way as they are serious value for money without a compromise on quality.

  17. T. Burrows

    Arrived in 2 days as promised. Good advice by sales guy before I purchased. My installer was very impressed with the tank.

  18. Paul Bradley

    Saved about 200 pounds compared to the next lowest cost unit. Very pleased with tank after inspecting it on arrival. Money I saved will be well spent elsewhere.
