Domestic UF System for
Rural Use with
Arsenic & Iron Removal Capability
- Pradip Lalla
Domestic Ultra Filtration SystemDeveloped and Patented by
Bhabha Atomic Research Centre
Dept of Atomic Energy, Govt. of India
Effective
Easy to operate & maintain
Economical
Delivers crystal clear water
Costs less than Rs. 1($ 0.02) per day per family

Economical Comparatively Costly Comparatively Costly
Cleaning is Physical and simple System Based, either through back wash or reject flow
Low Flux Very High Flux High Flux
• Indian population : 1.1 billion
• Absence of 24 hrs direct pipe supply
• Water is stored at Point of Use :
• Overhead Tanks
• Underground Tanks
• Loft Tanks
• Drums
• Kitchen Vessels
In spite of processing the raw water, contamination takes place at the
storage point & when the pipe is depressurized
Point of Use FiltersMuslin Cloth
Boiling the water
Ceramic candles
UV
Iodinated Resins
Slow release Chlorine
Nano Silver
BARC Technology UF System
Polysulfone Membrane Plastic Housing
Online system requiring 0.3 bar pressure
FeaturesRemoves suspended solids and
bacteriological contaminationCrystal clear waterPolishes the water to a sparkling cleanNo electricity/chemicalsEasy maintenance, empowers and
satisfies end-user
Access to membrane being straightforward
Maintenance is easyHomemaker is taught to clean and

Costing
Membrane Candle – Rs 150 ($3.50)Filter Housing – Rs 200 ($4.75)Pipes and AccessoriesJerry can with Float Valve for Collection-
Rs 250 ($5.70)Life of Membrane Candle 2- 3 yearsCost to family per day for water – less
than Rs 1 ($0.02)
Jaltara Single Unit•Flux/ Flow Rate of 3-6 Liters per hour
Jerry Can with Float Valve•Used for Collection of Water without the need for stopping the inlet source
Jaltara Double and Triple Unit•Flux/ Flow Rate Enhanced by connecting two and three membranes in parallel
Jaltara Deluxe Model•Flux/ Flow Rate Enhanced by connecting two and three membranes in parallel

Maintenance Contract (About Rs. 4000)
Other Tedious ProcessCandle Must Not be
Scratched or Allowed to DryBacteria Removal Efficiency is
Doubtful
Quartz Glass and UV Lamp Maintenance is Usually
Neglected Due to High Costs
Essential Minerals are Also Removed from the Water, Causes Leaching of
Minerals from the Human Body
