Integrated Spatial
Bio-Sequential (ISBS) Technology

A next-generation biological treatment platform that eliminates the activated sludge cycle — structurally designed for lower OPEX, smaller footprint, and compliance with the world's strictest discharge standards.

50% of WWTP costs go to sludge handling, for material that is 80% water.

Conventional technology has reached its limits

Conventional activated sludge is a homogeneous free-floating biomass requiring continuous recirculation, phase separation, and sludge disposal, a self-reinforcing cycle that cannot be fundamentally improved.

ISBS eliminates

01 Waste and return activated sludge (WAS & RAS)
02 Primary, secondary clarifiers & membrane dependency
03 Biomass management & handling
04 Near zero excess sludge

ISBS technology

A next-generation biological treatment platform designed to address the regulatory, economic, and infrastructure realities of future wastewater management. The ISBS platform removes the systemic causes of sludge, instability, and complexity.

[  Comparison  ]
Conventional technology
ISBS
Excess sludge
Large volumes: costly to treat, dewater, and dispose
Near-zero: excess activated sludge production.
Sludge recirculation
Mandatory: energy-intensive return to process start
Eliminated: clarifiers, sludge thickening, dewatering, drying, and RAS/WAS pumping systems
Chemicals & membranes
Regular chemical dosing; membranes require maintenance and replacement
Fully biological process:
No membranes, chemicals optional for P-removal only
Effluent quality
EU standard: COD ≤ 125, BOD₅ ≤ 25 mg/L
China Class 1A: COD ≤ 50 mg/l; NH₃-N ≤1.5 mg/l; TN ≤15 mg/l
Stricter than the EU standard. Proven at 40,000 m3/day
COD tolerance
Optimised for typical municipal loads: high-strength wastewater requires pre-treatment
COD load up to 5,000+ mg/l:
Handles municipal, industrial, and agricultural sewage
Shock load resilience
Load spikes destabilise the process and compromise effluent quality
Self-balancing: withstands flow fluctuations and COD spikes exceeding 50 - 100%
