X-Chip Technology for MBBR / IFAS Biological Treatment System

Proven fixed-film technology, ideal for BNR upgrades, and capacity expansions

The X-Chip technology incorporates a biomass carrier into a moving bed fixed-film process that provides a protected, extremely high surface area environment (>4,850m2/m3) for biofilm growth. The system increases capacity by 200% or more and ensures compliance with discharge limits—all within the existing plant footprint. The X-Chip technology can be used as an IFAS system or as a MBBR system. It provides complete bioreactor mixing with enhanced oxygen transfer capabilities.

High Surface Area X-Chip (> 4,850 m2/m3)

X-chip vs clogged media

X-Chip Technology installed at the largest centralised textile effluent plant in Vietnam. Entire WWTP footprint cut down by 50%.

APPLICATIONS

The X-Chip technology is ideal for plant upgrades, retrofits, or expansions of both municipal and industrial wastewater treatment plants. The flexibility and efficiency of the system also makes it a cost-effective solution for the construction of new plants, as well.

  • The X-Chip​ technology in an IFAS configuration combines biofilm and activated sludge systems for retrofitting existing plants for biological (TN) and total phosphorus (TP) removal.
  • Ideal for increasing plant capacity and improving effluent quality
  • Provides BOD removal with a very short hydraulic retention time (HRT)
  • Can be applied as a roughing filter for pretreatment or as a post-treatment polishing bioreactor

KEY BENEFITS

  • Cost effective – Design and implementation efficiencies ensure lower capital and operation costs than conventional alternatives.
  • Reduced maintenance –  Elimination of plugging
  • Nitrogen removal without increased hydraulic retention time
  • Fixed-film biomass is attached to carriers designed to remain in the aeration basin even under hydraulic upset conditions. Due to biofilm layers on the media, toxic upsets typically do not affect all active biomass and recovery is much quicker than with suspended growth systems.
  • Expandable - Simple media addition allows for easy plant expansion to accommodate population growth or other needs for capacity.
  • Reliable media retention - Efficient use of non-clogging wedge wire screens ensures reliable retention of the biomass carriers in the bioreactor
  • Durable - Heavy duty carriers can exceed 20-year life expectancy, even under intense bioreactor mixing conditions.

FEATURES

  • Small footprint – The system can successfully achieve BOD to < 5.0 mg/L, and enhanced nutrient removal performance, including total nitrogen (TN) < 3 mg/L without adding tanks to an existing plant. The high-rate treatment allows for a smaller footprint than conventional processes.
  • Flexible design - The treatment system integrates into most activated sludge bioreactors. It can also be applied as a roughing filter for pretreatment or as a post-treatment polishing bioreactor.
  • Expandable - Simple media additionally allows for easy plant expansion to accommodate population growth or other needs for capacity.
  • Stable operation - Toxic upsets and hydraulic "wash out" events do not affect the entire microbial population in the biofilm, ensuring smooth, and rapid system recovery.
