MBBR Technology – Moving Bed Biological Reactor (MBBR) systems are self-cleaning and unable to become blocked through channelling, unlike most fixed film media systems.

Market leading performance – Producing an excellent 97.5% pollutant removal level, the final effluent can be directly discharged into a stream or soakaway.

Low Maintenance Costs – Chamber one capacity is as much as 66% larger than other plants, making desludging intervals up to three times longer saving the owner significant costs.

Power Failure Default – The system keeps performing as a septic tank in the event of a power failure.

20-Year Life Expectancy – Ensuring that users benefit from a consistent, effective sewage treatment solution over two decades.

Frequently Asked Questions

How Does a Sewage Treatment Plant Work?

A sewage treatment plant works by processing wastewater through multiple stages to remove contaminants and produce effluent (treated water) that is safe for release into the environment.

The effluent (liquid waste material) from a sewage treatment plant meets the regulatory standards for discharge into a watercourse, river or stream. It has fewer pollutants and pathogens, providing an environmentally friendly and safe solution for wastewater management.

What Is The CAP Sewage Treatment Plant Process?

Sewage treatment plants employing Continuous Aeration Plants (CAP) utilising a specialised bio-media system to attain an outstanding pollutant removal rate of 96.2%. The design of this compact system is particularly effective in mitigating prevalent challenges encountered in small sewage domestic plants.

Through continuous aeration, organic matter is efficiently broken down, contributing significantly to the purification process. The bio-media configuration optimises the growth of beneficial microorganisms, ensuring enhanced treatment efficacy and environmental protection.

How Often Should I Conduct Sewage Treatment Plant Servicing?

The frequency of sewage treatment plant servicing can vary depending on several factors, including the size of the plant, its design, the volume of wastewater treated, regulatory requirements, and manufacturer recommendations.

However, here are some general guidelines for typical servicing intervals:

  • Routine Maintenance: Daily or weekly tasks like visual inspections, checking equipment for leaks, and monitoring chemical levels.
  • Scheduled Servicing: Monthly or quarterly activities including cleaning filters, inspecting pumps and motors, and calibrating instruments.
  • Annual Maintenance: Thorough cleaning of tanks, replacement of consumables and performance testing is conducted annually or biannually.
  • Regulatory Inspections: Periodic inspections and testing are required by regulatory agencies, typically annually or at specified intervals.
  • Emergency Repairs: Prompt addressing of emergency repairs to prevent system failures and environmental contamination, with response time varying based on severity.

Regular monitoring of your sewage plant performance is crucial for maintaining optimal operation and compliance with environmental standards.

What Is The Average Sewage Treatment Plant Cost?

The average cost of a sewage treatment plant can vary widely depending on several factors such as the size of the system, the technology used, the capacity it needs to handle, and the complexity of the installation process.

Small, domestic sewage treatment plants for individual homes or small buildings typically cost between £2,000 and £10,000. However, the price increases with the capacity needed to handle more wastewater, for example, commercial sewage treatment plants tend to be more expensive.
