Embodiment

[0291] The following examples show different ways of preparing an aqueous solution of calcium bicarbonate, known as calcium bicarbonate, using a multi-batch system comprising a master batch line and at least one slave batch line. The calcium bicarbonate solution obtained is then used for the remineralization of soft water, which may be, for example, natural soft water from groundwater or surface water sources, desalinated water from reverse osmosis or distillation, rainfall. Trials using a multi-batch system were carried out using different calcium carbonate products as raw materials for the preparation of the calcium bicarbonate solution.

[0292] All experiments were performed at room temperature (ie at a temperature between 15 and 25°C). It should be noted that the RO (reverse osmosis) water supplied at the beginning of each test had a temperature of about room temperature, ie 15 to 25°C.

Abstract

The invention relates to a multiple batch system for the preparation of a solution of calcium hydrogen carbonate and the use of such a dual batch system for the preparation of a solution of calcium hydrogen carbonate.

Description

technical field [0001] The present invention relates to a multi-batch system for the preparation of calcium bicarbonate solutions and the use of such prepared calcium bicarbonate solutions for remineralization of desalinated water or natural soft water and the use of multi-batch systems for the continuous preparation of calcium bicarbonate solutions use. Background technique [0002] Drinking water has become scarce. Even in water-abundant countries, not all water sources and reservoirs are suitable for producing drinking water, and many water sources are today threatened by a dramatic deterioration in water quality. The feed water initially used for drinking purposes is mainly surface water and groundwater. However, for environmental as well as economical reasons, the treatment of seawater, salt water, brackish water, waste water and contaminated effluent is becoming more and more important. [0003] To recover water (for drinking) from seawater or brackish water, severa...
