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.
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.
Uses: The pH correction of potable waters and the remineralisation of soft and desalinated waters
Juraperle is a filter fine granulation medium on the basis of fossil limestone structures. It is applied for increase the pH of poor water, and possibly iron removal. During filtration, the free CO2 is converted to bicarbonate and calcium is dissolved respectively. By this, the pH and hardness rate is raised. In addition, the iron is also filtered. Because calcium is dissolved, the product must be filled regularly.
