Bio-Lace
An advanced fixed-film media that delivers superior BOD, T-N, and T-P reduction — with no civil modifications or downtime.
Key Highlights:
- 95% BOD Removal
- Plug & Play Integration with STPs/ETPs
- Works in Rivers, Lakes, Tanks, Reactors
What is Bio-Lace®?
Bio-Lace® is an IFAS (Integrated Fixed-Film Activated Sludge) media developed by Euroclean USA and offered by Euroteck for retrofitting, upgrading, and optimizing wastewater treatment systems and natural water bodies.
Its braided polymer structure offers a massive surface area, allowing aerobic and anaerobic microbes to flourish symbiotically — enabling high treatment efficiency, less sludge generation, and rapid deployment without draining or downtime.
“From STPs and ETPs to lakes and rivers — Bio-Lace® turns any water body into a biological treatment reactor.“
Key Features & Benefits
- No Civil Modifications Needed: Easily retrofittable into existing systems, no reactor reconstruction required.
- High Microbial Load Capacity: Supports MLSS up to 8000 ppm, double that of conventional media.
- Resilient to Toxic Shocks & Load Surges: Works consistently under variable hydraulic and pollutant loads.
- Plug & Play Integration: Easily installed in aeration tanks, rivers, and natural waterbodies.
- Dual-Zone Microbial Growth: Aerobes on the outer surface, anaerobes near the core — promoting full nutrient breakdown.
- Less Sludge, Lower Maintenance: Built-in food chain reduces waste sludge production significantly.

How It Works
3-Phase Microbial Ecosystem for Water Purification
- Attachment Phase: Microbes are attracted to the positively charged fiber surface of Bio-Lace® and attach naturally.
- Growth Phase: Bacteria multiply rapidly, forming aerobic zones outside and anaerobic zones inside each fiber strand.
- Detachment & Dispersal: Biomass detaches as sludge and is easily removed downstream, reducing excess buildup.

FAQS
What makes Bio-Lace® different from conventional IFAS or MBBR media?
Unlike floating MBBR media, Bio-Lace® is a fixed string media with a higher surface area and superior microbial retention. It supports both aerobic and anaerobic bacteria, requires no mesh or barriers, and delivers higher BOD and nutrient removal with lower maintenance.
Can Bio-Lace® be added to an existing STP or ETP without modification?
Yes. Bio-Lace® is designed for drop-in retrofitting. It does not require tank modification, draining, or extended downtime — making it ideal for quick upgrades in operational plants.
How long does Bio-Lace® last?
The material has a lifespan of 15 years or more, thanks to the use of polyvinylidene chloride and polypropylene, which are highly resistant to wear, chemical attack, and microbial degradation.
What is the expected BOD, T-N, and T-P removal using Bio-Lace®?
In ideal conditions, Bio-Lace® achieves:
- BOD: >95%
- T-N: >90%
- T-P: >80%
It outperforms conventional systems even in low HRT environments.
Does Bio-Lace® reduce excess sludge generation?
Yes. Its food-chain-based microbial design ensures that anaerobes consume byproducts of aerobes, reducing sludge yield and disposal costs.
Can Bio-Lace® be used in natural water bodies like rivers and lakes?
Absolutely. Bio-Lace® can be deployed horizontally on riverbeds or lakebeds, promoting natural bioremediation by enhancing microbial activity and oxygen distribution.
How is Bio-Lace® installed in tanks or reactors?
Bio-Lace® cords are suspended using poles or grids, spaced 10 cm apart, and anchored to keep them submerged. The aeration system then supplies oxygen from below to activate microbial action.
Does the system require frequent cleaning or replacement?
No. Bio-Lace® is self-maintaining in well-designed systems. Unlike MBBR media, it doesn’t float or clog aerators and doesn’t need frequent draining or backwashing.
What are the typical industries or settings using Bio-Lace®?
Bio-Lace® is used in:
- Municipal STPs & ETPs
- Pharma & Chemical Industries
- Breweries, Fisheries & Food Plants
- Canal and River Cleanup Projects
- Residential Communities & Smart Cities
Yes. Bio-Lace® has proven to help achieve these standards efficiently with no major CAPEX upgrades, making it ideal for plants needing compliance with latest discharge guidelines.
