A Treatment Process Specific To Your Application!

There are a variety of treatment processes available, and the choice of process depends on the application typeFor example, a school wastewater treatment plant is only in use during school hours with little to no sewage entering the plant over weekends or holidays. In contrast, a busy restaurant has more concentrated and higher strength than school wastewater entering the system 7 days a week 18 hours a day. Read on for an explanation of the two main forms of sewage treatment we use.

SBR [Sequential Batch Reactor]

The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate under non-steady state conditions. An SBR operates in a true batch mode with aeration and sludge settlement both occurring in the same chamber. The major differences between SBR and conventional continuous-flow activated sludge system is that the SBR tank carries out the functions of equalisation, aeration and settlement in a time sequence rather than in the conventional sequence of continuous-flow systems. In addition, the SBR system can be designed with the ability to treat a wide range of wastewater volumes, whereas the continuous system is based upon a fixed flow rate.

The SBR system does not run constantly. If there is no sewage entering the sewage treatment plant the SBR process can detect this and enter ‘eco mode’. So for periods of non-use, the system does not keep constantly aerating and treating the sewage. The controlled nature of the SBR makes it ideal for an application with variable flows and where there are periods of non-use.

Typical examples where an SBR is the best choice include the following: schools wastewater treatment, creche wastewater treatment, caravan park wastewater treatment.

Advantages of the SBR process are as follows;

  • High degree of operational flexibility
  • No separate clarifiers
  • Low capital cost
  • Low power consumption
  • Very high effluent quality due to the controlled process

MBBR [Moving Bed Biological Reactor]

The MBBR is a recently developed form of sewage treatment. MBBR processes improve reliability, offer simple operation, and require less volume than traditional wastewater treatment systems. MBBR technology employs thousands of balls of plastic media operating in mixed motion within an aeration chamber. Each individual biocarrier increases productivity by providing a very high surface area for the growth of heterotrophic and autotrophic bacteria. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation.

This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically responds to load fluctuations. The MBBR has the following main benefits;

  • Compact design
  • Simple to expand by just adding more media to a tank
  • Single pass process with no need for transfer pumps or siphons
  • Low maintenance
  • Can deal with highly variable loads

    The system was installed by the Department of Education – who chose Biocell. But we have had a great experience dealing with the guys @ biocell from an operational viewpoint

    We do alot of work with Biocell. Just finished a project where we put in a 150 pop unit as part of our drainage contract for a housing development. Biocell got approval to switch to their system from the Council and provided all paperwork and documentation. A great job and everyone was happy.

    Very difficult site. Needed to install tank 9ft below the ground level. The concrete system made this very easy so made a big overall saving.

    The publican –

    My old victorian cesspit needed to be put into retirement. Bought a grease trap and sewage treatment plant from the guys at Biocell. Very professional. Their local installer did a turnkey job. USed a concrete system as its under the carpark. They even came back 3 weeks later to make sure all was working fine. For peace of mind I took out a maintenance contract too. Overall I was pleased with the job and it was done on time and on budget.

    I’m an installer. This is not my first biocell installed and it won’t be my last either!

    I am the PM on a job. I have limited experience with onsite wastewater treatment. Called a few suppliers but it was pretty clear immediately who knew what they were doing and who was not trying to take advantage of my lack of experience. Will be back to Biocell for my next off mains solution.

    Have a small pub in the west country. Space is limited so I needed to install in the car park. A concrete tank was a logical choice rather than buying a plastic one and surrounding it with concrete!

    A biocell system was specified by the engineer on a heritage railway visitor center. I usually deal with a different supplier – but I got such a good service and value for money I will use biocell water again.

    Far superior to the GRP unit I installed for my last commercial project.

    I have saved a FORTUNE on groundworks and concreting that would need to go around a plastic tank as I needed a very large 300 person system.

    Had a disc type unit installed. Caused nothing but trouble when we had busy weekends. Replaced in 3 months ago with a Biocell unit and I wish I had not done it sooner. Great company. 5+++
