Manufacturing/building method(s) Detail regarding solution production or construction method (instructions, mass production capacity, custom made,etc...)

Locally sourced clay and risk husks are processed, mixed with water, pressed into the filter shape and fired to a ceramic state, flow rate tested to ensure product consistency and coated with silver nitrate solution. It is made of a mixture of clay and rice husk burnt about 600-800º C which in turn produces a ceramic pot through a vitrification process (changing the nature of clay to ceramic). Ceramic properties that can absorb oxygen produce fresh drinking water such as jug water.

Average flow rate per day

10-35 Liters, depending on pattern of use

Maintenance Schedule

How often/when should maintenance be performed?

When the filtration rate reduces it can be cleaned up with a scrub pad and water, but soap should not be used.

Chemical residual

There is a potential for silver in filtered water, below secondary guideline values of 0.1 mg/L

End of life indicator (yes/no)

Replace filter if it breaks, there are visible cracks or chips, or filtration rate does not rejuvenate to a satisfactory rate after scrubbing.

Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The product consists of ceramic pots which have taps and lids attached. It comes in 4 different varieties based on the quality of outer body and size.

Specifications: Height: 48 cm; upper diameter: 35 cm; unit weight: ~8 kg. Flow rate 1-3.5 liters per hour.

Technical support Technical support provided by

To rejuvenate flow rate when filters clog, users scrub ceramic filtering element with a brush.

Replacement components Availability of replacement components (in-country, by order,...)

Available locally: tap for dispensing water, safe storage container, ceramic filtering element.

Lifecycle Disposal and warranty

2-3 years depending on turbidity of source water

Manufacturer specified performance targets Designer / Manufacturer specified targets

Performance targets: 2 log reduction in bacteria, and to some extent reduces iron and manganese content in the water.

Vetted performance Findings of manufacturer evaluations or independent testing centers

The product has been recognised and supported by international organisations as well as government.

Testing organizations Independent lab, academic research centers, etc.

Filters are tested at a local accredited laboratory for physical, chemical and bacteriological characteristics.

Safety Potential hazards / risks related to operation of this product
