WCSEE Hybrid™ Biological Treatment

• Rotational multi-pass flow: Continuous circulation generates multiple passes over the media, improving effluent polishing without increasing tank size or media load.
• Continuous internal recirculation: Effluent repeatedly cycles through the biozone, sustaining performance under variable and diurnal loads.
• Neutrally buoyant media (310): Supports strong biofilm attachment while maintaining active biomass in suspension. Minimises sludge buildup and reduces maintenance requirements. (Typical media life: 20 years).
• Low-shear operating Environment: Reduces turbulence and abrasion, protecting media, reducing microplastics risk and extending service life.
• Enhanced nutrient removal: Extended contact time promotes stable biofilm development and improved nitrogen and nutrient reduction. Configurable with anoxic zones to meet regulatory targets.

Effluent quality

The WCSEE Hybrid™ system consistently meets stringent effluent standards, with configurable nutrient removal for site-specific requirements:

• Ammonia: <0.4 mg/L
• Phosphorus (P): optional add-on (chemical dosing) for site-specific removal
• Total Nitrogen (TN): configurable with anoxic zones
• BOD & COD: meets high treatment standards for biochemical oxygen demand and soluble chemical oxygen demand

Effluent Quality Targets

• Ammonia: <0.4 mg/L
• Phosphorus: Optional add-on for P removal
• Total Nitrogen: Configurable with anoxic conditions
• BOD/COD: Meets high treatment standards (site-specific design and commissioning)

• Optimised reactor use
• Full tank volume utilisation: Lower media fill combined with continuous recirculation optimises hydraulic efficiency, maximises capacity and ensures consistent treatment under variable loading.
• Energy savings with built-in energy-saving timers: Can achieve up to 65% reduction in blower energy compared to traditional systems (site-specific).
• Variable speed drive blowers: Deliver 50–100% of design requirements, ensuring operational flexibility.

• No mechanical or electrical moving parts in cells: Reduces complexity, lowers failure risk and simplifies O&M planning.
• No tank desludging or media removal: Minimises downtime and simplifies inspections and component replacement.
• Consistent performance: Continuous recirculation reduces risk of untreated pockets.

• Compact smaller footprint: – typically up to 30% smaller than comparable SAF and MBBR technologies, subject to configuration and site requirements.
• Modular & scalable: Off-site construction enables quick installation, flexible deployment and redeployment if requirements change.
• Reduced civil works – can be installed on a flat gravel bed foundation, minimizing civil construction needs.
• Adaptable vessel options: Steel, concrete or GRP containment. Suitable for above- or below-ground installations.

• Factory-fitted control kiosks: Include blowers, panels and optional telemetry.
• UK manufactured: High-quality, quality-controlled production with locally sourced components.
• Customisable Integration: Optimised for new or existing vessels of any shape or size.

• Reduced media wear & microplastics risk: Low-shear operation protects media and the environment.
• Optimised resource use: Lower media fill and hydraulic efficiency reduce material and energy consumption.
