WaterQuest Mobile™


WaterQuest Mobile™ is one of the Innovative decentralized solution to provide fresh drinking water in Coastal areas, areas with poor ground or surface water. The WaterQuest Mobil is configured to produce from 20 M3 to 100 M3/Day of drinking water suitable to treat all types of water sources - Sea water, Brackish water, River water, Lake water, bore well water, highly turbidity water.

Process Calculations

A combined numerical and experimental approach was used to optimise the module/system design, resulting in ∼20% permeate flux enhancement. Experimental results revealed that the system can produce 16 L per square meter of membrane area per hour (LMH) at a salinity level of 80 ppm from a ∼2000 ppm groundwater when it is feed at 1 m3/h at 8 bars. This indicates that a vehicle equipped with 12 m2 of tubular RO membranes can deliver 1 m3 of drinkable water by using ∼0.9 L of diesel. Assuming eight such systems could be implemented in a community to fulfil the water demands for a village with 2000 residents, a social business study revealed that a payback time of 2.5 years is achievable, even if the sale price of the water is relatively low, Rs 12 per 20 L, which is half of the lowest market price, including providing a goods transportation service at price of Rs 500 per 100 km.

Operation Troubleshooting and Maintenance Procedure

Operation and Maintenance includes mainly two units of the system



As general this vehicle needs periodic servicing oiling and greasing. Vehicle comes with 1 year limited and 2 year battery warranty.


Desalination Unit

Periodic replacement of membranes and filters are required as per TDS value of source water for efficient desalination procedure.
