Abstract

DC60 (27/02/58) A water treatment apparatus comprising a first treatment tank having a first stationary bed, on top of which is a powdered phosphorus adsorbent consisting of an inorganic coating compound, wherein this first bed separates phosphorus and solids from water and recaptures the phosphorus in the state adsorbed on the phosphorus adsorbent in the first bed; a second treatment tank having a second fluidized bed or stationary bed comprising the phosphorus adsorbent, wherein this second bed separates phosphorus from water received from the first treatment tank and recaptures the phosphorus in the state adsorbed on the phosphorus adsorbent in the second bed; and a conveying line arranged to convey the phosphorus adsorbent with phosphorus adsorbed in the second treatment tank from the second treatment tank to the first treatment tank. Edit brief of invention 27/02/58 A water treatment apparatus comprising a first treatment tank having a first stationary bed, On top consists of a powder phosphorus adsorbent composed of an inorganic coating compound, wherein the first bed separates phosphorus and solids from water and recaptures phosphorus in the state adsorbed on the adsorbent. Phosphorus in the first bed, a second treatment tank with a fluidized bed or a second stationary bed consisting of a phosphorus adsorbent, wherein the second bed separates phosphorus from the water received from the first treatment tank and recaptures phosphorus in the state adsorbed on the phosphorus adsorbent in the second bed and a conveyor belt arranged to transport the phosphorus adsorbent with phosphorus adsorbed in the second treatment tank from the second treatment tank to the first treatment tank. ------------------------------------------------ The water treatment unit consisting of a first treatment tank with a stationary bed, the first bed consists of a powder phosphorus adsorbent composed of a compound. Coated with inorganic layer, where this first bed separates phosphorus and solids from water and recovers phosphorus in the state adsorbed on the phosphorus adsorbent. Phosphorus in this first bed, a second treatment tank with a fluidized bed or a second set of stationary beds consisting of phosphorus adsorbent, where this second bed separates phosphorus from the water received from the first treatment tank and recovers phosphorus in the state adsorbed on the phosphorus adsorbent in this second bed and a conveyor belt arranged to transport the phosphorus adsorbent with phosphorus adsorbed in the second treatment tank from the second treatment tank to the first treatment tank.
