The filter is fitted with a system which uniformly distributes the raw feed water at the base of the sandy filter bed via ring-type distributor.

The water passes through the bed (more…)

Continuous regeneration sand filters.

The standard model is made with wetted parts manufactured in AISI 304,
the support legs in treated and painted carbon steel, filter element of quartz sand of suitable grain size. Special executions and alternative materials are available on request.

Typical applications: tertiary treatment of civil and industrial waste water, surface water clarification, treatment of drinking water, primary filtration of civil and industrial waste water, clarification of metallurgical industry cooling water, algae removal, pre-treatment for ultra-filtration membrane installations, pre-treatment for ozonisation plants, finishing treatment with active carbon.

System advantages

• Low first costs and plant management costs
• High efficiency and reliability for the removal of suspended solids, even colloidal
• Exclusive backwash system which uses raw water rather then filtered water
• External sand recirculation system
• Ease of installation
• Possibility of gravity feed, thanks to its low pressure drops
