OUR TECHNOLOGIES

Core Treatment Technologies

Our treatment systems are built around proven biological and membrane technologies, engineered to deliver consistently high-quality effluent with minimal operator involvement.

TECHNOLOGY 01

MBR — Membrane Bioreactor

The MBR process combines biological treatment with membrane ultra-filtration, requiring smaller activation tanks with no buffering limitations and higher purification efficiency. The ultra-filtration stage eliminates the need for additional cleaning steps — no chlorine, UV, or activated carbon required.

Untreated sewage enters via a lifting station and passes through an automatic 1mm fine screen. Screened solids are transferred to a waste container automatically, without operator intervention.

  • Smaller tank footprint — no extra buffering needed
  • No chlorine, UV or activated carbon post-treatment
  • Automatic 1mm fine screening on inlet
  • Extended aeration — activated sludge principle
TECHNOLOGY 02

MBBR — Moving Bed Bio Reactor

The MBBR system is a highly efficient biological treatment technology for domestic and industrial wastewater. Reiken Solutions has advanced this technology by employing Biochips — unique carrier media whose shape and motion characteristics prevent clogging.

The Biochip’s movement in wastewater creates shear forces that maintain permanently thin biofilms, and its high biodegradation performance reduces the required volume of carrier media — resulting in a smaller reaction tank footprint.

  • Biochip carrier media — no clogging by design
  • Permanently thin biofilms via shear forces
  • Reduced carrier volume — smaller tank required
  • Suitable for domestic & industrial wastewater

Ultrafiltration Systems

Industrial-grade UF systems removing suspended solids, bacteria, and high-molecular-weight contaminants from process and potable water streams.

  • ✔  Hollow fibre membrane modules
  • ✔  Bacteria & pathogen removal
  • ✔  RO pre-treatment integration

Reverse Osmosis

High-performance RO systems for desalination, demineralisation, and the production of ultrapure water for industrial and commercial processes.

  • ✔  Desalination & demineralisation
  • ✔  Ultrapure process water output
  • ✔  Energy-efficient multi-stage design

Activated Sludge & SBR

Fully biological sewage treatment plants using continuous-flow activated sludge or Sequential Batch Reactor (SBR) processes for flexible, reliable treatment.

  • ✔  Continuous flow activated sludge
  • ✔  Sequential Batch Reactor (SBR)
  • ✔  Fully biological — chemical-free
SYSTEM DESIGN

Built for Reliability, Scalability & Compliance

ISO Container-Based

CSC-approved ISO Norm containers with HDPE-lined internal walls protect the system from raw wastewater contact.

Modular & Scalable

Capacity can be expanded by assembling multiple container units — from 300PE up to 100,000PE — without redesigning the entire system.

Odour-Free by Design

Specifically designed to operate without odour, making our systems ideal for sensitive residential and commercial environments.

ATV & EU Compliant

All designs comply with ATV standards and EU regulations, adhering to BSI, CIBSE, and ASHRAE guidelines using advanced engineering software.

Low Maintenance

High cleaning performance with low maintenance requirements — automated processes minimise daily operator involvement.

Reusable Effluent

Treated effluent consistently meets reusable quality standards — suitable for irrigation, cooling water, and non-potable applications.

HDPE Tank Option

Where ISO containers are unsuitable, equipment is installed in HDPE tanks — offering flexibility for any site configuration.

24/7 O&M Support

Round-the-clock operations and maintenance support — monitoring, servicing, and emergency response to keep your plant running at peak performance.
