1 Membrane Filtration Units for Industrial & Domestic Applications
We Care Our Customer

2 Membrane Filtration Applications
Ultra filtration Membranes - Removal of Turbidity, Bacteria and Viruses, with Pre-filtration and Post filtration other contaminants can also be removed. Reverse Osmosis Membranes - Removal of Salts and other ions.

3 Absolute System Integrator
Strong Engineering Team for Technology Research and Procurement Highly Trained Staff Strong Reliance on Engineering Strong Partnerships with Original Equipment Manufacturers (OEM) Export Based Manufacturing Systems Acknowledged as Manufacturer of WFP by Engineering Development Board

4 Membrane Technology

5 Aqua Refine Pro with Pre-Filtration
Standard capacities of 2m3/hr & 4m3/hr drinking water customizable for other production capacities. Designs available for upto 2.0 IMGD plants. Depth Filtration through sand filters to remove turbidity. Taste & Odor treatment through granular activated carbon filters (GAC) Arsenic removal through absorption by Granular Ferric Hydroxide (GFH) media. Fluoride removal through Active Alumina media. Nitrate removal through Cationic Ion Exchange Resin Media Hardness Control System through Anionic Ion Exchange Resin media Bacteriological Contamination through Ultra Filtration membrane certified for 99.99% (Log4) virus removal and % (Log6) bacteria removal. Online disinfection through Sodium Hypo-chloride injection (optional) PAC /PLC controlled operation of whole plant including backwashing of whole system. Mimic on plant for operator assistance. Remote monitoring of whole system over GPRS/GSM networks Standardized reporting software module. All the components certified to NSF / KIWA / CE

6 Design Criterion - Strong Reliance on Engineering
System Requirements Capacity (Quantity) Installation Type (Mobile or Fixed) Output requirement (Quality) Selection of UF Membranes Encased or submerged Membrane Material Hydrophilic / hydrophobic Structure for strength (Single bore / multiple bore) Production methodology (Single continuous body, Double skin) Mode of operation (Inside-out / outside in) Cross Flow / Dead End Cleaning processes Backwash (Top/Bottom), Forward Flush (Top/Bottom), CEB, CIP.

7 Design Criterion - Strong Reliance on Engineering

14 Three paths to fresh water.
KSB provides reliable solutions to support all three standard methods of extracting fresh water from the sea: 1. RO (Reverse Osmosis) pumps seawater at very high pressure through selectively permeable membranes, separating salts from the water. 2. MSF (Multistage Flash) is a rapid evaporation process, in which seawater is flashed-heated into steam and condensed. 3. MED (Multiple Effect Distillation) passes seawater through evaporators in multiple stages which is systematically condensed at low temperatures and pressures. Whatever method is applied, KSB is able to leverage extensive experience in the energy field to optimize operations, maximize performance and ensure the lowest costs for energy and maintenance.

21 RO - Feed Water Limiting Conditions RO - Role of Pre-treatment
Oxidizing agents like chlorine COD & BOD within limits Oil & Grease Nil SDI Less than 5 pH range from 3 to 11 Turbidity less than 1 To reduce particulates & Improve SDI Clarification / Filtration Polymer / coagulant addition Micro Filtration Minimize scaling & fouling Softening Acid & anti scalant addition Anti scalant addition Chlorine Removal Carbon filtration Bisulfide addition Minimize Silica Scaling Antiscalant addition Softening & pH Control Turbo circulator Controlling Organic Dissolved Organic Colloidal Organic RO - Terminology Feed - Product / Permeate - Brine Reject Recovery = Product Flow / Feed Flow Salt Passage = Product TDS / Feed TDS Salt Rejection = 100% - Salt Passage in %

22 RO - System Components Pre-treatment Clarification Coagulation
Filtration / Ultra filtration De-chlorination Dosing System (anti scalant, etc.) Cartridge filter RO Membrane System Membranes Pressure Tubes High Pressure Pump Energy Recovery System Control Panel Cleaning System Tank Filter Pump Post Treatment DM Plant pH adjustment Degasification Raw feed water to supply water to the pre-treatment Pre-treatment for turbidity, TSS, colloidal particle & organics UF/Cartridge filter to remove ultra small particles to control SDI (Silt Density Index) Anti scalant dosing system High pressure pump & feed control valve to pressurize the feed water to membranes Membranes are housed in FRP pressure vessels / tubes. A reject control valve to control the recovery of the system Flow indications to measure permeate & reject flow Pressure gauges/sensors to measure the quality of permeate water Cleaning system consisting of tank, CF, pump Operating Parameters: Feed - Pressure, Concentration, pH, temperature. Permeate - Concentration, Flow, pressure Reject - Flow, Pressure, concentration Instrumentation used: pH meter, Conductivity meter, Rota meter, Pressure gauges, ORP meter, Level switches, Pressure Switches, Electrical controls.

23 RO - Fouling / Scaling Fouling Types Scaling from Hardness Salts
Scaling by Silica Fouling by Metal Oxides Plugging by suspended solids Biological fouling Scaling The deposition of sparingly soluble salts onto the membrane surface and / or feed channel material Scaling occurs primarily in the down stream elements because of the high concentrations existing in this portion of the RO system Common scalants include Calcium Sulphate, silica, and Calcium Carbonate

24 Energy recovering strategies: Comparison of efficiencies
100 % spec. Energy consumption without ERS ~64 % spec. Energy consumption with Turbine – ERS Efficiency of Turbine System: % Further Reduction of specific Energy Consumption Turbine- Isobaric ~47 % spec. Energy consumption with Isobaric ERS Efficiency of Isobaric ERS: % Conclusion: Lowest Energy Consumption with Isobaric ERS
