Lecture 16: Case Study | Nanofiltration Design & Cost Analysis for Herbicide Removal

Welcome to Lecture 16 of the Complete Membrane Technology Course.
This is the final lecture of the theoretical module! In this session, we apply everything we've learned so far to a real-world Case Study: Designing a Nanofiltration (NF) plant to treat groundwater contaminated with herbicides.

We walk through the complete engineering calculation process—from selecting the membrane element to determining the final cost per cubic meter of water produced.

🔹 What you will learn in this lecture:
Case Study Overview: Treating groundwater contaminated with "Callisto Herbicide" ($1.55 \mu g/L$) to meet drinking water standards ($0.1 \mu g/L$).
Membrane Selection: Why we chose the "NANO-BW MAX" element based on spacer thickness and fouling potential.
Step-by-Step Calculations:
1. Permeability: Calculating Lp ($5.67 L/m^2.h.bar$) using manufacturer test data.
2. Max Recovery: Determining the limit (87%) based on herbicide rejection and concentration factors.
3. System Sizing: Calculating the required membrane area ($18,500 m^2$) and total number of elements (500 modules).
4. Staging: Designing a 2-stage array (55:28 pressure vessels).
Economic Analysis:
Estimating Investment Costs (CAPEX).
Calculating Annual Fixed, Maintenance, and Energy costs.
Final Result: Determining the total water production cost ($0.1538 €/m^3$).

🔹 Next Up:
This concludes the theoretical part of the course. In the next lecture, we start the practical software training using **ROSA (Reverse Osmosis System Analysis)**.
