Dissolved Air Flotation Systems

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. - 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

The flow of oil and water is introduced to the tank and distributed in a homogeneous way across the whole cross-section. They are composed of a containment tank which can be manufacturedfrom treated and painted carbon steel or AISI 304 stainless steel; lamellar pack with parallel channels in rigid polystyrene, stabilized agains UV radiation. Special materials and executions are available on request. Typical applications: first fall rain water, petrochemical plants, mechanical workshops, refineries and depots of hydrocarbons, washing of vehicles, land reclaim, refuse handling centres. -High solid-liquid separation efficiency -Simplicity of installation and operation -Compact execution -Low first costs and plant management costs

The flow of oil and water is introduced to the tank and distributed in a homogeneous way across the whole cross-section. They are composed of just the parallel channel lamellar pack in rigid polystyrene, stabilized against UV radiation, closed in an AISI 304 containment frame; they are normally employed for housing in concrete tanks specifically built for the purpose of holding lamellar packs. Features Available height: 0,85 m Available widths: from 0,60 m to 2,20 m Available lengths: from 1,00 m to 3,00 m -High solid-liquid separation efficiency -Simplicity of installation and operation -Compact execution -Low first costs and plant management costs

The flow of water and sludge coming from the previous phases of treatment (whether biological or physical-chemical) is introduced into the intermediate zone of the tank, just below the lamellar pack. Lamellar pack single-piece clarifiers for the sludge settling. They are composed of: containment tank which can be manufactured from, at choice, treated and paintedcarbon steel or in AISI 304 stainless steel; lamellar pack with parallel channels in rigid polystyrene, stabilized against UV radiation; surface discharge trough (with weir) in AISI 304; intermediate distributor of the feed flow. Special materials and executions are available on request. FM – L SERIES (11,30 m2/m3 equivalent surface) Typical applications: secondary clarification of biological sludge, drinking water plants, upgrading of existing clarifiers, rain water treatment. -High solid-liquid separation efficiency -Simplicity of installation and operation -Compact execution -Low first costs and plant management costs
