These units are solar photovoltaic (PV) driven, battery-less, off-grid, stand-alone Ultrafiltration (UF) systems for water purification. On sunny days, they can be operated for 9 - 10 hours/day. They are capable of removing un-dissolved species such as, dust, turbidity, microorganisms etc. from drinking water. 
The units are available in two sizes:

1) 10 lph capacity for domestic use 
2) 100 lph capacity for community use

SALIENT FEATURES

• No need of grid electricity, battery or overhead tank
• The UF water purifier based on BARC technology can be upgraded by integrating it with the solar power unit
• Compact and light weighted, can be used as mobile units.
• The solar power unit is a one time investment.
• No day- to - day maintenance and running cost.
• No chemicals required.
• Filtered water is devoid of pathogens, turbidity & colour.
• By using the pump, the productivity/ capacity of any gravity-operated water purifier can be enhanced by around 2 times.

APPLICATIONS

These units are best suited for remote/rural areas where electricity is not available or the voltage is not stable. They can be used in urban areas also. As they are portable, they will be of great help for people working in desert areas, as in the case of defense personnel.

WORKING PRINCIPLE

In these units, water purification takes place by a pressure driven, membrane based process called ultrafiltration. 
Electricity required for pressurization is generated with the help of solar PV system.

APPLICATIONS

These units are best suited for remote/rural areas where electricity is not available or the voltage is not stable. They can be used in urban areas also. As they are portable, they will be of great help for people working in desert areas, as in the case of defense personnel.

RAW MATERIALS

All the components are available in Indian market. Technology for UF based water purifier operating under tap pressure can be obtained from BARC as a separate/additional technology.

SPACE REQUIRED

For doing assembly/ integration of the components, a space of 10 m² (min) area is required. Testing is done outside. Area requirement for storage of materials can be decided by the party, as it will vary depending on the amount of inventory.

MANPOWER REQUIREMENT

Assembly is manual and simple. One single person can assemble a unit, following the provided P&I diagram. Testing/operation also can be done by a single person who knows normal operation of a pump.
