The **W-3012-R2-FS30-B** refers to a high-performance, industrial-grade **Membrane Water Treatment Element**, specifically an Reverse Osmosis (RO) membrane manufactured by companies like DuPont (FilmTec). While this is a mechanical filtration component, its performance is governed by physicochemical principles and it is often integrated into automated systems with electronic controls. --- ## 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Membrane Type** | Polyamide Thin-Film Composite | | **Active Area** | 30 sq. ft. ($2.8 m^2$) | | **Feed Spacer Thickness** | 30 mil (Enhanced fouling resistance) | | **Permeate Flow Rate** | ~2,500 Gallons Per Day (GPD) | | **Stabilized Salt Rejection** | 99.5% | | **Applied Pressure** | 225 psi (15.5 bar) | --- ## 2. Electronic Integration and Control Although the membrane itself is "passive," the **W-3012-R2-FS30-B** functions as the heart of a system regulated by the following electronic components: ### A. Pressure & Flow Sensors To ensure the membrane operates within safety limits, the following electronics are used: * **Transducers:** Convert hydraulic pressure into 4-20mA or 0-10V signals for a PLC (Programmable Logic Controller). * **Digital Flow Meters:** Pulse-output meters track the "Permeate" (clean water) vs. "Concentrate" (waste) ratio. ### B. Water Quality Monitoring (Conductivity) The efficiency of the **R2** (High Rejection) membrane is measured using **Electronic Conductivity Probes**. These probes measure the Total Dissolved Solids (TDS) by calculating the electrical conductivity of the water, allowing the system to trigger an alarm if the membrane fails. ### C. VFD (Variable Frequency Drives) The "B" in the sequence often relates to specific industrial batching. To maintain the precise 225 psi required for this membrane, **VFDs** are used to control the high-pressure pump motors, adjusting speed based on real-time sensor feedback to save energy and protect the membrane surface. --- ## 3. Key Electronic Definitions in Part Numbering While the part number represents physical attributes, they dictate the **electronic setpoints** of the system: * **R2 (High Rejection):** Requires high-sensitivity conductivity sensors to detect minor fluctuations in salt passage. * **FS30 (Fouling Summary/Spacer):** The 30-mil spacer reduces pressure drops, which means the electronic pump controller (VFD) encounters less resistance compared to standard 28-mil spacers. * **W (Water):** Standardized for tap or brackish water electronic sensor calibrations. --- ## 4.
