Backwash pH Filter

  • General Description

    Water with a pH below 7 is acidic and has a corrosive nature. Acidic water corrodes the copper pipe-work and heating systems found in domestic and industrial plumbing systems. The copper dissolves out and is deposited on fixtures and fittings leaving unsightly green stains. Raising the pH will neutralise the water stopping the corrosivity, removing the metallic taste. The simplest way to raise the pH of water is to pass the water through a vessel containing slowly dissolving calcium and magnesium salts. These salts slowly dissolve into the water 're-mineralising茠?? the water and naturally raising the pH. The water can be simply passed through the media through an in/out head or through an automatic backwashing filter head. The backwashing head has the advantage of remixing the media and also removing any debris which may have been oxidised out of solution as the pH increases.

    Important Notes Regarding Selection

        When selecting a suitable filter, care should be taken to ensure you have enough water available to backwash (clean) the filter correctly. For example if you have a flow rate of 1.5m3/hr, you may select model 1054/WS1/FS, however this unit will require a flow rate of 2.3m3/hr to backwash for a period of approx 15mins. You would therefore require 575ltr of water for the backwash process at a flow rate of 2.3m3/hr to clean the filter efficiently.露每

        A minimum pressure of 2bar at eh filter is required for operation.

        A drain is required for the filter to gravitate the waste water into during backwash.

        Not suitable for pump systems operated via float switches.
