Limestones for industrial effluent treatment - Import export

Mitadaf is an innovative dissolved air flotation system. Its exceptional solid/liquid separation and/or sludge thickening efficiency is the result of the combined systemof uniform hydrodynamics and filtration with a bed of micro air-bubbles: an equipment of new concept developed by MITA. The heart of the mitadaf system is the multifunctional central column, by means of which the raw sewage is introduced into the tank, the clarified effluent water is recovered and the sludge exits. The raw influent water, suitably saturated with air, is introduced into the flotation tank via a series of holes located in the lower part of the central column. The entering mix, propelled by the micro-bubbles of air, immediately reaches the surface, homogeneously distributed across the whole flotation area (uniform hydrodynamic system).

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
