Algae blooms are a growing concern in lakes and ponds across India and around the world. These blooms can cause serious problems—from oxygen depletion and foul odor to mass fish die-offs and degraded water quality. If you’re searching for how to remove algae from lakes naturally, this blog will guide you through proven eco-friendly solutions, and how Clean-Water is playing a crucial role in restoring lake health using nature-based methods.
Why Algae Blooms Happen
Algae naturally occur in most aquatic ecosystems, but when the growth becomes excessive, known as an algae bloom—it poses environmental and health risks. The primary reasons behind algae overgrowth include:
-
Nutrient Overload: High levels of nitrogen and phosphorus from sewage, fertilizers, or organic waste fuel algae growth.
-
Still or Warm Water: Stagnant, nutrient-rich water in summer accelerates bloom formation.
-
Poor Oxygen Levels: Low dissolved oxygen (DO) in water makes it harder for aquatic life to survive, while algae thrive.
The Problems with Chemical Removal
Conventional methods like algaecides or chlorine-based cleaners may give quick results, but they come at a cost:
-
Harm aquatic life
-
Leave chemical residues
-
Require repeated applications
-
May worsen the problem in the long run
That’s why more communities and lake managers are looking for natural ways to remove algae from lakes.
Natural Methods to Remove Algae from Lakes
1. Floating Wetlands
Floating wetlands are floating structures made of special plants and bio-media that clean water as they float. These wetlands absorb nutrients like nitrogen and phosphorus—the primary food source for algae. Without nutrients to feed on, algae die out naturally.
✅ Eco-friendly
✅ Enhances biodiversity
✅ Long-lasting
Clean-Water specializes in designing customized floating wetlands for lakes, ponds, and rivers across India. Our bioengineered floating wetlands provide 5x more surface area for microbial activity than conventional pipe-based designs.
2. Beneficial Microbial Cultures
One of the most effective and natural ways to remove algae from lakes is by using Beneficial Microbial Cultures (BMC). These microbes digest organic sludge and excess nutrients, starving algae at the root cause.
Benefits of Clean-Water’s BMC:
-
Breaks down harmful compounds
-
Improves water clarity and quality
-
Controls algae and foul odor
-
Harmless to aquatic life
Used in over 100 million liters of water across India, Clean-Water’s BMC is trusted by municipalities, industries, and CSR-led lake rejuvenation projects.
3. Aeration Systems
When oxygen levels fall, algae bloom more easily. Installing aerators re-oxygenates water and disrupts the conditions algae need to thrive. Clean-Water’s solar-powered floating aerators add oxygen to the water without requiring electricity.
Why Aerators Work:
-
Maintain healthy DO levels (>5 mg/L)
-
Prevent algae and fish deaths
-
Circulate water to prevent stagnation
Clean-Water also introduced India’s first Lotus-Shaped Floating Solar Aerator, combining aesthetic appeal with high performance.
4. Shade and Surface Covers
Algae require sunlight to grow. Reducing light penetration can naturally limit their growth. Floating wetlands and aquatic vegetation provide natural shading for the lake surface, helping curb algae proliferation.
