Modular Wastewater Plants
What is a KEE modular water treatment plant?
A KEE modular water treatment plant is a scalable, pre-engineered Rotating Biological Contactor (RBC) system designed for efficient wastewater biological treatment. Featuring patented Managed Flow® technology, these self-contained GRP units treat up to 750 Population Equivalents (PE) per module (scalable up to 5,000 PE). They deliver high-performance BOD removal, nitrification, and nutrient reduction with low energy consumption and low life-cycle costs.

Next-Generation Modular Water Treatment Plants for Variable Flows
When upgrading existing facilities or installing new decentralised wastewater infrastructure, operators require reliable, compliant, and cost-effective biological treatment systems. A KEE Process modular water treatment plant combines robust engineering with patented Managed Flow® technology to deliver consistent effluent quality under fluctuating hydraulic and organic loads.
Constructed from structural-grade Glass Fibre Reinforced Polyester (GRP), each modular wastewater treatment unit resists both ground pressure and corrosive environments. Whether deployed above or below ground, these systems offer fast installation, whisper-quiet operation, and low total cost of ownership across a 30+ year service life.
Core Engineering Capabilities & Process Modules
- BOD Reduction (DC Modules): Dedicated biological treatment units engineered specifically for high-efficiency Carbonaceous Biochemical Oxygen Demand (BOD5) removal.
- Nitrification & Nutrient Removal (DN Modules): Specialised biological treatment modules tailored for full nitrification, total nitrogen reduction pathways, and target biological phosphorus removal.
- Patented Managed Flow® Technology: Built-in surge control mechanism that dampens hydraulic peaks, ensuring continuous, stable biological processing without wash-out risks.
- Scalable Architecture: Designed to manage flows up to 1000 Population Equivalents (PE) in a standalone unit, or combined in modular arrays for communities and industrial sites up to 5,000 PE.
- Silent, Energy-Efficient Operation: Driven by direct-coupled gearmotors, KEE Rotating Biological Contactors require very little power and operate virtually silently, with zero odour nuisance.
Applications & Integration Options
- Upgrading Non-Compliant Facilities: Easily integrated upstream or downstream of underperforming legacy systems to increase capacity or meet stricter discharge consent levels.
- New Residential & Commercial Developments: Rapid-deployment, self-contained units that reduce on-site civil engineering overheads.
- Industrial Wastewater Treatment: Pre-treatment or full biological treatment modules for food processing, agricultural, and commercial trade effluents.
Frequently Asked Questions
How does a KEE modular water treatment plant handle peak load fluctuations?
All KEE modular units incorporate patented Managed Flow® technology. This integral mechanical equalisation system cushions hydraulic surges and balances organic loading variations, maintaining a stable biological environment and preventing short-circuiting or biomass washing.
What are the installation requirements for a modular wastewater treatment plant?
KEE delivers modular RBC units as pre-engineered, factory-tested assemblies. They can be installed directly above ground on a simple concrete slab or buried below ground level depending on site aesthetics and hydraulic head requirements. Simple pipe connections and power supplies allow rapid commissioning.
What ongoing service and operational support options are available?
KEE Services provides comprehensive nationwide maintenance, emergency breakdown support, and fully managed operation packages. Fixed-price service contracts ensure long-term regulatory compliance, optimal energy performance, and complete operational peace of mind.
