Green & Low-Carbon Prefabricated Wastewater Treatment Plant
Short construction period | Small footprint | Low investment | Low operating cost
Water Magic Cubes 4.0 perfectly integrates the advanced BIOCOS process with welding-free assembly structure, empowering wastewater treatment with intelligent manufacturing and helping customers achieve green transformation and sustainable development. The product solves industry pain points and outperforms traditional concrete plants in construction period, investment, land occupation and environmental protection. It provides customers with an all-scene solution that is efficient, land-saving, time-saving and worry-free.
Safe Structure
ZCEN has established the Prefabricated Water Plant Innovation R&D Base with the China Institute of Building Standard Design & Research, focusing on R&D and design of steel structures for prefabricated water plants to build a safe and low-consumption structural system.
Advanced Process
Adopting the BIOCOs process invented by Prof. Ingelr of the University of Innsbruck, Austria, it is an enhanced biological nitrogen removal process combining alternating A/O and endogenous denitrification. It integrates biochemical reaction and sedimentation in one compact system, featuring: strong nitrogen removal, land efficiency, fewer equipment, low energy consumption, low external carbon demand, low sludge yield and easy operation.
Safe Structure
Safe & Stable Structural System
A complete "beam-column-slab" structural system is designed considering permanent loads (self-weight, internal water pressure) and variable loads(seismic, wind, snow, geological settlement).
Welding-free Assembly & Triple Sealing
On-site installation uses bolted connections for welding-free assembly, speeding up construction and improving quality. ZCEN′s patented triple-seal structure ensures safe, zero-leakage tank performance.
Flexible Configuration & Process Compatibility
Beams, columns, and slabs adopt standardized design for fast production and high universality. The structure can be flexibly adjusted to match various common water treatment processes.
Green & Prefabricated Advantages
Lower Carbon Emissions：Reduces reinforced concrete consumption and cuts use of cement, sand, formwork, machinery, and labor; overall carbon emissions reduced by over 70%.
Shorter Construction Period：Standardized design, intelligent manufacturing, and prefabrication. On-site assembly like "building blocks". Construction period: approx.3 months, saving over 80% time.
Greener Construction：Reduces civil engineering works by over 90%, minimizing dust, noise, waste, and sewage.
Welding-free Connection：Standardized, prefabricated beams, columns, and slabs feature strong interchangeability and universality. All on-site connections are bolted, with no welding required.
Process Flow
Process Description
The BIOCOs process consists of 1 P Tank, 1 B Tank and 2 SU Tanks:
P Tank: Anaerobic tank, mainly for biological phosphorus removal.
B Tank: Anoxic+ aerobic(alternating A/O) tank for denitrification and nitrification.
SU Tank: Static sedimentation tank with alternating operation for continuous effluent, sludge recycle, mixing, sedimentation and endogenous denitrification.
Process Advantages
Enhanced nitrogen removal: Strengthened endogenous denitrification; effluent TN≤8 mg/L in stable operation
Simplified equipment: Blowers used for aeration, mixing and recycle; lower investment and operation cost.
Lower energy consumption: Low DO control at A/O end; precise aeration reduces power consumption.
Lower carbon source demand: Adapts to low C/N ratio; no external carbon needed when influent C/N≥2.8.
Strong shock resistance: High sludge concentration and retention capacity.
Flexible & compact layout: Modular design; over 20% land saving vs. conventional A2O.
Application Scenarios
Water Magic Cubes can be flexibly configured for various processes, including AAO, MBR, SBR, high-density sedimentation, magnetic coagulation filter and other rectangular tanks. Suitable for:
