Zeoclere 30 is a granular filter media most commonly used for the reduction of ammonia from water supplies. The grade described on this sheet is Zeoclere 30, which is available in >1-2mm and 0.5- 1mm grain size.

Zeoclere is a selected high-grade zeolitic mineral from a family of 40 different types. The Zeoclere range is specifically for use in pressure or gravity filters. It has a purity of between 80-85% and is constant between these percentages. The material has been shown to operate well in both small and large pressure vessels. In tests carried out using a 1 metre column with the flow in a constant backwash mode for 180 days - (24 hours), showed a material loss of 23mm due to attrition.

• Under correct conditions chemical reduction will be achieved along with water saving, power cost and less maintenance.
• High ammonia removal (average 23.8gm/lt.) Dependent on flow rate.
• Iron removal efficiency is high. Far greater surface area than sand.
• Removes odour. Longevity 5 - 7 years.
• Turbidity shown to be up to 60% better than accepted silica sand standard.
• Reduced backwashing by up to 70% over that of sand.
• No health hazard.
• Zeoclere has a far greater (400%) surface area than silica sand. Therefore, backwashing -where appropriate - can be dramatically reduced.
• Because of the high reduction of ammonia removal, the use of chlorine is similarly reduced and on average is quoted that up to 40% savings have been achieved.

• Colour - light grey (MgO = 85%).
• Hardness - 4 Moh
• Grain size - >1-2mm
• Pore volume approx. 5-10%.
• Bulk density 998kg/m3.
• Stability from pH3 - pH12.
