General properties.. how to use MagpHlow 

Bulk bed density = 1.8 kg per litre

Magphlow consist of small spheres (2.0 to 6mm) . The MagpHlow  are used in the form of a contact bed through which the water passes. The MagpHlow  dissolves slowly in response to acidity in the water, and during the process the pH and magnesium hardness of the water are increased. 

 At a pH of 8.3 MagpHlow  is insoluble in the water,  as the pH becomes more acidic, the solubility of MagpHlow  media increases,  the product therefore has a built in pH buffering capacity.      Due to the pH increase on the Magphlow surface the product is also excellent for heavy metal reduction.

In effluent treatment systems with ammonium, and phosphate, there is a reaction with the formation of Struvite that is an ammonium magnesium phosphate mineral This is the same mineral that forms kidney stones.  Struvite forms on the surface of the magphlow media and is removed during the back-wash phase.  For this application the MagpHlow media must be used with AFM active filter media, and back-wash must fluidise the bed by 30%. Back-wash flow required equates with 50m/hr for 5 minutes.

The Magphlow can be held in either existing sand filters, pressure sand filters pressure AFM filters or gravity flow filters, they can even be spread in the vicinity of water intakes. In each of these situations the performance of the MagpHlow  bed is literally automatic and no sophisticated pH metering equipment is required. All that is required is that the bed should be topped up with fresh MagpHlow  every few months to replace the MagpHlow  which have been used.
