The poster presentation of our phosphorus removal and recovery technologies won the “Water Convention 2011 BEST POSTER RUNNER-UP” award given by the “Water Convention 2011 Program Committee”.
The award recognizes our product “REPHOSMASTER series - Phosphorus Removal/Recovery System” with the outstanding advanced process that recovers phosphorus, which would otherwise cause eutrophication in waters and is also an exhaustible resource, in the form of magnesium ammonium phosphate (also known as MAP which can be used as fertilizer) or hydroxyapatite (also known as HAP) for reuse.
* The Water Convention 2011, an international research conference, was held concurrently with the “Singapore International Water Week 2011 Water Expo” (at Suntec Singapore International Convention & Exhibition Centre), where Swing Corporation had an exhibition booth.
About “REPHOSMASTER series - Phosphorus Removal/Recovery System
The system recovers phosphorus, which has been disposed of as waste, in the form of magnesium ammonium phosphate (also known as MAP) or hydroxyapatite (also known as HAP). It is beneficial not only in improving the water environment, but also in recycling phosphorus. In the REPHOSMASTER series, several types are available depending on whether a wastewater treatment plant has a sludge digester or not.
The REPHOSMASTER - MAP type, which is designed to recover phosphorus from digested sludge, has the following features.
■Phosphate-phosphorus removal/recovery ratio of 90% or more
Our original mechanical-mixing type crystallization reactor efficiently recovers MAP directly from digested sludge. The system is expected to considerably reduce problems in sludge treatment arising from phosphorus.
■Recovered phosphorus (in the form of MAP) purity of 90% or more
Using a crystallization technique, high purity phosphorus can be recovered. Because of its low heavy metal content, it can be registered as fertilizer.
■Reduces the phosphorus load in the water treatment system
The phosphorus removal in digested sludge reduces the phosphorus load in the mainstream water treatment process, which eventually improves the effluent quality. If the plant uses chemicals to remove phosphorus in the water treatment process, the system considerably reduces the amount of required chemicals.
■Reduces the amount of sludge produced
The recovery of phosphorus from digested sludge reduces the solids content of dewatered cake as well as the amount of sludge ash.
