pH Correction

Water in which the pH is below 7 is acidic. Acidic water accelerates corrosion in pipe work, causes staining of baths, sinks and other appliances and can leave a distinctive metallic taste to the water.

pH correction media

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 and can also reduce any iron or manganese contamination.

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 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 or iron or manganese which may have been oxidised out of solution as the pH increases.

There are vessel dome holes options in which the pH media can be topped up without having to take off the valve.

Juraperle
Juraperle is a granular media made up of 99.4% calcium carbonate. It has a superior performance to limestone due to its micro-crystalline structure. It dissolves very slowly, is free from soluble constituents and has a low silica content. Juraperle is consumed and from time to time new media should be added.

Corrosex
Corrosex is a highly reactive magnesium oxide salt and is used most effectively where the pH correction is substantial or the flow rate is high. In reality for a pH of less than 6 a 25% Corrosex, 75% Juraperle mix is ideal.

Backwash Flow Requirements
10x54 = 1.6m3/h
13x54 = 2.3m3/h
