Successful Pilot Trial of T1BTM Pond & Lake Cleaner for Lake Bioremediation in Riaba, Malabo
- Client: Local Authorities, Riaba, Malabo
- Conducted By: Team One Biotech LLP
- Trial Period: 25th April – 5th May 2025
- Technology Used: T1B™ Pond & Lake Cleaner – Microbial Bioremediation Solution
Background
Due to nutrient pollution (high phosphate and nitrate levels), the lake in Riaba, Malabo was experiencing notable ecological damage defined by:
- Algal Bloom: High phosphate and nitrate levels of nutrient contamination cause too rapid algal development.
- Sludge Accumulation: Two feet or more of organic sludge accumulated at the bottom of the water body.
- Foul Odour: Strong anaerobic decomposition odour, especially during windy conditions.
- Ecological Imbalance: Low dissolved oxygen (DO) levels affecting aquatic health.
Team One Biotech was engaged to pilot a microbial bioremediation approach using T1B™ Pond & Lake Cleaner, recognising the need for an environmentally sustainable solution.For more information or to collaborate on similar projects, Contact Us
Action Plan – Trial before Actual
Before initiating full-scale bioremediation of the lake, a pilot trial was strategically designed and executed to serve as a proof of concept. This small-scale trial aimed to:
- Validate the effectiveness of T1B™ Pond & Lake Cleaner in a controlled environment. Understand product behaviour, microbial activity, and degradation patterns when exposed to real lake water conditions, including the presence of algae and organic sludge.
- Simulate real-world conditions (aeration, nutrient load, microbial dose) in a manageable setting using a 200-litre drum.
- Establish dosing protocols, response timelines, and key indicators for success (e.g., reduction in BOD, ammonia, and visible algal blooms).
- Reduce the risk of large-scale deployment by gathering actionable data and visual proof of water improvement.
- By conducting this pilot trial, Team One Biotech ensured a data-driven, confident, and customized approach to lake restoration. The outcomes from this trial form the foundation for scaling the treatment across the full lake body, with scientifically backed expectations for ecosystem rehabilitation and lake bioremediation aiming to restore ecological balance sustainably.
Project Objectives
1. Apply Advanced Bioremediation: Using T1B Pond & Lake Cleaner.
2. Restore Ecosystem Health: Cleanse and revive the water body.
3. Achieve Reductions In: Algal bloom – Nutrient levels (Nitrates, Phosphates, Ammonia) – Sludge volume – Foul odours
4. Enhance Water Quality: Improve clarity and DO.
5. Use Natural Microbial Technology: Target breakdown of pollutants and pathogens.
Methodology
- Setup: A 200-litre drum filled with lake water containing visible algae and organic sludge.
- Aeration: Continuous air supply to simulate natural mixing and oxygenation.
- Dosing: 100g/day of T1B™ Pond & Lake Cleaner.
- Observation Period: Daily monitoring of clarity, odour, algal reduction, and biological activity.
The Solution:
- Natural microbial strains tailored for aquatic ecosystems.
- Proprietary enzyme-plant extract blend.
- Time-release formulation for sustained bioremediation.
Targets organic sludge, odours, and excess nutrients (ammonia, nitrates, phosphates).
Before vs After (10-Day Results)
| Parameter | Before | After | Change |
| BOD (mg/L) | 5.4 | 4.9 | -9.26% |
| DO (mg/L) | 5.2 | 4.8 | -7.69% |
| Phosphate (mg/L) | 1.0 | 1.0 | No Change |
| Ammonia (mg/L) | 0.5 | 0.3 | -40.00% |
| pH | 8.2 | 8.0 | -2.44% |
Key Observations After 10 Days
- Algal Bloom: Noticeable reduction in algal density.
- Water Clarity: Improved water clarity
- Odour: significantly controlled
- Biological Activity: Aerobic biological activity initiated
Conclusion & Recommendations
The trial successfully validated the potential of T1B Pond & Lake Cleaner in restoring lake water quality through natural and sustainable microbial bioremediation. The results showed measurable reductions in pollutants and improved clarity and ecological conditions within just 10 days.
Recommendation: Scale up the in-situ application across the lake using T1B Pond & Lake Cleaner, supported with significant aeration and regular monitoring.
