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)
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. Nalco 9916 Msds
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
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

The NALCO 9916 (also known as OPTIMER 9916) is a liquid flocculant primarily used in water treatment systems, such as primary and secondary clarifiers and flotation devices. Critical Safety Information
According to the Material Safety Data Sheet (MSDS) guidelines for this product:
Hazard Overview: Classified as a Warning level product. It causes skin and eye irritation and is combustible.
Acute Health Effects: Inhalation of high concentrations can cause nausea, dizziness, vomiting, or unconsciousness.
Chronic Health Effects: Prolonged skin contact may cause dermatitis and defatting of the skin.
Incompatibilities: Avoid contact with strong oxidizers (e.g., chlorine, peroxides, nitric acid) as these can generate heat, fires, or toxic fumes. Personal Protective Equipment (PPE) Standard precautions for handling NALCO 9916 include: Eyes: Chemical splash goggles or a face shield.
Hands/Skin: Rubber, neoprene, nitrile, or PVC gloves and standard protective clothing. 12–15
Respiratory: Usually not required with adequate ventilation, but use an approved respirator if vapors form. Preparation & Handling
Dissolution: The product must first be dissolved in clean water, often using automatic mixing systems. For optimal performance, a successive dilution to 0.05% prior to dosing is recommended.
Water Quality: Avoid using recycle water high in suspended solids, mineral salts, or iron, especially if the pH is below 6.5 or above 7.8.
Equipment Materials: Use PVC, polyethylene, Teflon, or stainless steel for pumps and lines. Do not use aluminum, brass, copper, or carbon steel. Storage & Disposal
Shelf Life: Minimum of 12 months when stored in original unopened containers under normal conditions.
Conditions: Keep containers tightly closed to prevent moisture ingress and keep away from heat or open flames.
Disposal: Wastes may meet hazardous waste criteria under RCRA (40 CFR 261). Consult local environmental agencies for proper disposal of excess product or rinsate.

Purpose: This document summarizes the typical hazard categories, handling precautions, and first aid measures associated with Nalco 9916. It is not a substitute for the manufacturer's official SDS.
Nalco (now part of Ecolab) produces specialty chemical formulations for industrial water treatment, pulp & paper, oil & gas, and other process industries. A product labeled “Nalco 9916” is likely a proprietary industrial chemical blend used for corrosion control, scale inhibition, biocide support, or similar water-treatment roles. The exact formulation is proprietary, so the SDS is the primary public source describing hazards, composition ranges, safe handling, and first-aid measures.
