Submersible Mixer Installation: How to Handle Ponds Without Concrete Walls?

Summary: Installing a submersible mixer in a pond or lagoon without concrete walls can be challenging. The most reliable solution is a Floating Pontoon System. This guide explains how to choose between FRP and Stainless Steel floaters for your wastewater treatment project.

The Challenge: Installing Mixers in Wall-less Ponds

In many wastewater treatment plants, equalization tanks and anoxic tanks are built with sturdy concrete walls, making mixer installation straightforward. However, for open ponds, earth lagoons, or tanks with geomembrane liners, traditional wall-mounting is impossible.

To ensure efficient mixing and prevent sediment buildup in these environments, a floating installation is the industry standard.

The Solution: Customized Floating Pontoon Systems

At Nanjing LJ Water Treatment Equipment Co., Ltd, we provide specialized floater systems designed to maintain the optimal hydraulic position of your submersible mixer.

Comparison: FRP vs. Stainless Steel Pontoons

1. FRP Pontoons (For Smaller Mixers)

For mixers with an impeller diameter below 620mm, we recommend Fiberglass Reinforced Plastic (FRP) pontoons.

• Lightweight: Easy to deploy and reposition.

• Corrosion-Resistant: Ideal for harsh chemical environments.

• Cost-Effective: A budget-friendly choice for smaller-scale operations.

2. Stainless Steel Pontoons (For Heavy-Duty Mixers)

For larger units with impellers 620mm or wider, we provide Stainless Steel pontoons.

• High Strength: Built to withstand the torque and thrust of powerful motors.

• Maximum Stability: Ensures the mixer stays in the optimal hydraulic position.

• Long-Term Durability: Designed for decades of service in industrial conditions.

Why Use LJ Submersible Mixers for Pond Applications?

A floating system is only as good as the mixer it supports. Our mixers are engineered for 24/7 reliability in demanding conditions:

• Self-Cleaning Impeller: The hydrodynamic design prevents debris entanglement, crucial for open pond environments.

• Dual Protection: Equipped with Class F insulation and IP68 protection to ensure motor longevity.

• Premium Components: Standardized with NSK bearings (customizable to SKF) and dual independent mechanical seals.

• Energy Efficiency: Optimizes oxygen transfer when integrated with aeration systems, lowering overall operational costs.
