What you'll learn

  • Definition of membranes. Classification of membranes. Different Membrane technologies present in water and wastewater treatment . Design equations such as salt passage %,recovery% to design UF and RO system. Pre-treatment system of RODesigning a Reverse Osmosis and Ultrafiltration system based on design equations. Designing a Reverse Osmosis system via the ROSA software.

Course content

1 section • 6 lectures • 2h 36m total length

  • Introduction17:15

    This will be an introduction to what are membranes,how these membranes are classified and how membranes are prepared. The different types of membrane technologies are also discussed

  • Reverse Osmosis18:25

    In this unit we would learn about TDS and how based on TDS the source of water is classified. Also the design equations  such as recovery,flux in order to design the Reverse Osmosis system is discussed. The flux range for each source of water is also discussed in this section

  • Pre-treatment of Reverse Osmosis System-Dual Media Filtration& Ultra-filtration38:03
  • Pre-treatment for Reverse Osmosis-Activated Carbon and Chemical pretreatment10:22

    This unit will cover the pre-treatment methodologies by chemicals(antiscalants,sodium bisulphite and acid/alkali). This unit also will cover the design of activated carbon.

  • Reverse Osmosis-Stage,Pass wise Treatment and Design equations for the RO system15:06

    This unit will cover the Pass and stage wise treatment system of Reverse Osmosis.In this unit the design equations such as flux,recovery and no of membranes will be covered to design the Reverse osmosis system. The process and instrumentation diagram of the reverse osmosis system is covered.

  • Case Study- DMF,UF,RO and also designing RO by ROSA software57:25

    This unit covers a case study which involves the design of DMF,UF,Reverse Osmosis system. Also with the help of ROSA software the Reverse Osmosis system is solved.

Requirements

  • Chemical Engineering,Biotechnology

Description

Membrane classification and different membrane technologies will be covered in this. The classification of water based on TDS along with the flux range for each of the source will be discussed. Pre-treatment technologies such as activated carbon filter,dual media filter(DMF) and chemical pre-treatment is discussed in detail. Ultrafiltration(UF) is explained as a pretreatment as well as a membrane filtration technology. The design equations and the process flow diagram (filtration,backwashing and cleaning process) of the Ultrafiltration system is discussed. The pass and stage wise Reverse Osmosis (RO) system is discussed.The design equations and the process and instrumentation diagram of the Reverse Osmosis system is also discussed. Case studies involving the design of DMF,UF and RO system is discussed. The design of RO system with the aid of ROSA software is also discussed.
