Phos-4-Fade® Phosphorus Removal Tablets

Slow-Release Aluminum Sulfate Tablets for Wastewater & Stormwater Treatment

Product Overview

Phos-4-Fade® phosphorus removal tablets provide a consistent and effective method for reducing phosphorus levels in wastewater, stormwater, and process water. Containing 93% aluminum sulfate, these tablets are the safest and preferred method of choice for phosphorus removal in municipal, industrial, and residential treatment systems.

They directly address the root cause of harmful algae blooms by eliminating phosphorus from the food chain before it reaches sensitive waterways.

Why Phosphorus Removal Matters

Excess phosphorus in water bodies is a primary contributor to environmental degradation. When nutrient-rich effluent enters waterways, it often triggers rapid algae growth. These harmful algae blooms deplete oxygen levels, damage aquatic ecosystems, and degrade water quality. By using Phos-4-Fade®, facility operators can proactively lower phosphorus levels to protect local water resources.

Reducing phosphorus is also essential for regulatory compliance. Many treatment facilities face strict limits on nutrient discharge to improve effluent quality. Phos-4-Fade® serves as an integral part of a nutrient reduction program, helping systems meet stringent environmental standards without the complexity of liquid chemical dosing systems.

How Phos-4-Fade® Works

Aluminum Sulfate Chemistry

Each tablet is formulated with 93% aluminum sulfate (Al₂(SO₄)₃) as the active ingredient. As the tablet dissolves, it releases this coagulant into the treatment stream. The aluminum sulfate reacts chemically with phosphorus (in the form of phosphate) present in the water.

Coagulation and Binding

The released coagulant bonds with phosphates to form insoluble particles. This chemical reaction effectively neutralizes the phosphorus, preventing it from acting as a fertilizer for algae.

Settling Mechanism

Once the aluminum and phosphorus combine, the resulting particles settle to the bottom of the treatment tank or lagoon. This sediment remains contained within the system until it is removed during routine disposal, ensuring the effluent leaving the tank is significantly lower in phosphorus content.

Flow-Proportional Dosing

Phos-4-Fade® tablets are engineered to release aluminum sulfate in direct proportion to the velocity of the incoming flow. This means the dosage automatically adjusts based on the volume of water entering the system, providing consistent treatment even during variable flow conditions.

Integration Before Chlorine Contact

For maximum effectiveness, these tablets should be incorporated into the treatment process in conjunction with clarification, but before a chlorine contact tank. If using a multi-tube feeder, they can be used simultaneously with disinfection steps, provided they are in separate feed tubes.

Performance Advantages

• Concentrated 93% aluminum sulfate formula ensures potent phosphorus reduction.
• Slow, consistent dissolution provides reliable, long-term treatment without frequent reloading.
• Chemical release automatically adjusts to incoming flow velocity for optimal dosage control.
• Minimizes sludge generation compared to liquid or granular alternatives that often overdose.
• Eliminates the need for complex chemical mixing or liquid solution preparation.
• Offers more accurate dosing than liquid or granular alum, preventing chemical waste.
• Provides a cost-effective long-term treatment solution for nutrient reduction compliance.

Applications & System Compatibility

Phos-4-Fade® is versatile and suitable for a wide range of water treatment scenarios:

• Wastewater treatment plants: Improves effluent quality and meets discharge permits.
• Stormwater systems: Treats runoff to prevent nutrient loading in local waterways.
• Process water systems: Manages phosphorus in industrial water outputs.
• Agricultural runoff control: Mitigates fertilizer impact from surrounding land.
• Food processing facilities: Handles nutrient-rich waste streams effectively.
• Vacation & residential systems: Works efficiently in low, intermittent, or variable flow conditions common in homes and retreats.
• Feeder Compatibility: Compatible with all major gravity or pressure-rated tablet feeders.

Installation & Feed Tube Loading

Placement Within Treatment Process

Phos-4-Fade® should be placed in the treatment stream after clarification, but before the final discharge. If a chlorine contact tank is used, the tablets should be applied before it is used. The chlorine contact tank can then serve as a mixing chamber for the coagulation process.

Tube Loading Instructions

1. Remove the feed tube from the dispenser housing and remove the protective cap.
2. Rinse the tube and cap with fresh water to remove any residue. Do not use a tube that contains remnants of other chemicals.
3. Hold the tube slotted end up at a 45° angle.
4. Slide Phos-4-Fade® tablets into the tube one at a time, ensuring they lie flat.
5. Replace the cap securely and return the tube to the housing with the slotted end down.
6. Ensure the tube rests evenly on the floor of the housing.

Multi-Tube Feeder Guidance

If using a Bio-Dynamic® tablet feeder with multiple tubes, consult the manufacturer’s instructions for correct tube placement.

Simultaneous Chlorination Compatibility

You can use Phos-4-Fade® in the same feeder as Bio-Sanitizer® disinfecting tablets, but they must be in separate feed tubes. Never mix different types of tablets within the same tube. If a feed tube is not charged with chlorine tablets, the tube closest to the outlet may be filled with Phos-4-Fade® tablets.
