Tunsai (Rabbit) Ceramic Water Purifier

Locally sourced clay and rice husk are processed then mixed with water, pressed into the filter shape, fired to a ceramic state, flow rate tested to ensure production consistency and coated with silver nitrate solution.

Users can obtain filters through a network of 600 retail centers throughout the (Cambodian) provinces. Sales averaged about 26,000 per year from 2006 to 2010, but increased to nearly 47,000 in 2011 with the new factory working near full capacity (4,000 pots per month) and the launch of the Super Tunsai and the direct sales network

Village-to-village water filter sales. Hydrologic recruits and trains commissioned sales agents, each of whom coordinates with village chiefs to arrange group sales meetings in about 20 villages per month.

Hydrologic can also arrange to export Tunsai water filters to countries around the world. To date, Hydrologic have exported to resellers in Yemen, Sri Lanka and Vietnam.
