How does the BioClean domestic sewage treatment system work?

The Biocell BioClean is a plug and play domestic 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 BioClean sewage treatment plant. Coarse bubbles break down solids, thereby reducing the need for a large primary chamber.
  2. The remaining wastewater flows into the secondary zone. In this chamber, it mixes with activated sludge to kick start the biological treatment process. Any remaining solids settle out in this step.
  3. The small air blower activates and runs, aerating the wastewater via the bubble diffusers in the next chamber of the tank. This mixes and oxygenates the wastewater, allowing naturally occurring bacteria to develop, multiply and feed on the organic material and nutrients. The bacteria clean and decontaminate the sewage to industry leading standards.
  4. During the final settlement phase, any remaining fine solids in the wastewater settle to the very bottom of the tank producing (activated) sludge which flows back to the primary chamber. The water in the final chamber is now clean and ready for discharge to the soakaway or stream/watercourse.

What happens to the sludge?

Sludge accumulates inside the BioClean which has a total capacity of 3,500l. Like all treatment plants, the sludge should be removed on a regular basis by a professional sewage disposal company who pump it out and take it away for disposal. This is the most economical way to tackle sludge in domestic wastewater treatment systems.

Do I need a riser kit?

A riser kit is only required for deeper than standard installations. Ask your site engineer if in any doubt.

  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.

    • James Clarke

      Hi Herman, please forward your details to sales@biocellwater.com and a member of our team will get back to you.

  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 sales@biocellwater.com. 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.
