Techniques

Chapter 1: Techniques

Clarisep: Ultrafiltration for Oily Wastewater Treatment

Clarisep, a technology developed by Pall Corporation, utilizes ultrafiltration as its primary treatment technique. This method involves forcing oily wastewater through a semi-permeable membrane with extremely small pores. These pores are carefully engineered to allow water molecules to pass through while effectively rejecting larger oil droplets, suspended solids, and other contaminants.

Key aspects of the Clarisep ultrafiltration technique:

• Membrane Material: Clarisep membranes are typically made from high-performance polymers designed to withstand harsh environments and resist fouling. These materials possess excellent chemical and thermal stability.
• Pore Size: The pore size of the membrane is meticulously chosen to ensure optimal separation of oil and water. The size is generally in the nanometer range, effectively blocking larger oil droplets while allowing water to pass through.
• Pressure Differential: A pressure difference is applied across the membrane to drive the flow of wastewater through the pores. This pressure can be generated using pumps or other pressure sources.
• Filtration Mechanism: The filtration process occurs as oil droplets and other contaminants are physically intercepted by the membrane, while water molecules pass through the pores. This mechanism results in a clean water permeate and a concentrate stream enriched in oil and other contaminants.

Advantages of Ultrafiltration for Oily Wastewater Treatment:

• High Efficiency: Ultrafiltration systems like Clarisep can achieve impressive oil removal rates, often exceeding 99%, leading to clean water that meets stringent discharge standards.
• Versatility: This technique can effectively handle a wide range of oil types and concentrations, including emulsified oil and free oil, making it suitable for various industries.
• Minimal Chemical Use: Ultrafiltration requires minimal chemical additives, reducing the environmental impact and operational costs associated with chemical treatment methods.
• Reduced Sludge Generation: Unlike sedimentation and other traditional methods, ultrafiltration produces a much smaller volume of concentrated sludge, simplifying waste management.

Chapter 2: Models

Clarisep System Configurations: Tailored Solutions for Diverse Needs

The Clarisep system is available in various configurations to accommodate different wastewater volumes, oil concentrations, and treatment requirements. Here are some commonly employed models:

1. Single-Stage Clarisep: This configuration utilizes a single ultrafiltration stage to treat oily wastewater, effectively separating oil from water in a single pass. It is often employed for applications with relatively low oil concentrations and moderate treatment demands.

2. Multi-Stage Clarisep: For wastewater with higher oil content or stricter discharge requirements, multi-stage configurations are employed. These systems utilize multiple ultrafiltration stages, allowing for progressively finer filtration and achieving superior oil removal rates.

3. Clarisep with Pretreatment: For wastewater containing high levels of suspended solids or other contaminants, a pretreatment stage is often incorporated. This stage can involve physical processes like sedimentation, filtration, or coagulation to remove these contaminants before the ultrafiltration stage.

4. Clarisep with Post-Treatment: Depending on the specific application and desired water quality, post-treatment options can be integrated. These include disinfection, demineralization, or polishing stages to further enhance the quality of the treated water.

Factors influencing model selection:

• Wastewater characteristics: Oil concentration, type of oil, presence of suspended solids, and other contaminants.
• Treatment objectives: Desired oil removal rate, water quality requirements for discharge or reuse.
• Process capacity: Required flow rate and treatment volume.
• Cost considerations: Capital and operational costs associated with different system configurations.
