Technical Overview: Nalco 9916 (Optimer 9916) Nalco 9916, also known as Optimer 9916, is a high molecular weight, high-charge cationic flocculant in powder form. It is primarily utilized in industrial and municipal wastewater treatment for solid-liquid separation processes. 1. Applications and Use

Nalco 9916 is designed for high-efficiency performance in various dewatering and clarification applications:

Sludge Dewatering: Ideal for use with centrifuges, twin-belt presses, screw presses, and plate-and-frame filter presses.

Wastewater Treatment: Employed as a settling aid in primary and secondary clarifiers, as well as in flotation devices (DAF/IAF).

Filtration: Used in raw water treatment and filtration systems to improve water clarity. 2. Chemical and Physical Properties Form: Off-white to white micronized powder.

Active Constituents: Acrylamide co-polymer with a high cationic charge. Solubility: Completely soluble in water. Odor: Typically odorless. 3. Handling and Storage (Safety Data) This report summarizes the safety, handling, and technical

According to standard Safety Data Sheet (SDS) guidelines for this product:

Protective Equipment: Standard precautions include the use of safety goggles and rubber gloves.

Compatibility: Equipment such as pumps and lines should be made of PVC, polyethylene, Teflon, or stainless steel.

Caution: Do not use aluminum, brass, or carbon steel in direct contact with the clean product.

Storage: Store in original, unopened containers in a cool, dry place. Keep containers tightly closed to prevent moisture ingress, which can cause the powder to clump or degrade.

Shelf Life: Typically 12 months from the date of shipment under normal storage conditions. 4. Potential Health Hazards Handling: Use with adequate ventilation

Inhalation: High concentrations of dust or vapors may cause nausea, dizziness, or stupor.

Skin Contact: Prolonged contact can cause drying and irritation (dermatitis).

Spills: Large spills should be contained using non-combustible absorbent materials like sand or earth. Avoid discharging directly into waterways as the product may be toxic to aquatic life.

Preparation Note: To use Nalco 9916, it must be dissolved in clean water at a concentration of 0.1% to 0.3% and allowed to "mature" or age before application. NALCO 9916

7. Handling and Storage

• Handling: Use with adequate ventilation. Avoid generating mists. Wash hands after handling. Do not eat, drink, or smoke in work area.
• Storage: Store in original closed container in a cool, dry, well-ventilated area away from strong oxidizers, acids, or bases. Protect from freezing (if water-based).
• Incompatibilities: Strong oxidizing agents, chlorine, and bleach can cause exothermic reaction.

1. Hazard Identification

According to the data sheet, Nalco 9916 typically carries specific signal words and pictograms.

• Signal Word: Often Warning.
• Health Hazards: The primary concern with this product is usually Skin Corrosion/Irritation and Serious Eye Damage/Eye Irritation. It can cause severe eye damage if not washed out immediately.
• Physical Hazards: It is generally non-flammable and not explosive, making it easier to store than solvent-based chemicals.

2. Hazard Identification (Based on similar Nalco phosphonate/polymer blends)

Likely Classification (per OSHA GHS):

• Not classified as hazardous in some formulations, OR
• May cause skin corrosion/irritation – Category 2 (reversible irritation)
• May cause serious eye damage – Category 1 (irreversible effects possible)
• Specific target organ toxicity (single exposure) – Category 3 (may cause respiratory irritation)

Signal Word: Warning or Danger (depending on concentration of active ingredients like phosphonates, acrylic polymers, or azoles).

Key Hazard Statements:

• Causes serious eye irritation.
• Causes skin irritation.
• Harmful if swallowed (if containing certain azoles or corrosion inhibitors).
• Toxic to aquatic life with long-lasting effects.

9. Physical & Chemical Properties

• Appearance: Liquid
• pH (concentrate): Typically 2.0 – 4.0 (acidic)
• Specific Gravity: ~1.10 – 1.20
• Solubility in Water: Complete
• VOC Content: 0% (typical for water-based treatments)

Health and environmental concerns worth spotlighting

• Corrosivity and irritation: Many water-treatment chemicals are corrosive; even diluted exposures can cause burns to skin and eyes.
• Environmental risk: Discharge to waterways can harm aquatic life; SDS will specify biodegradability and aquatic toxicity.
• Chronic exposures: Repeated inhalation or skin contact with certain proprietary additives (e.g., some surfactants or amines) can cause dermatitis or respiratory sensitization in susceptible individuals.
• Reactivity with other plant chemicals: When mixed with oxidizers or strong acids/bases, unexpected reactions can release heat or toxic gases — strictly follow compatibility guidance.
