WATER TREATMENT 17 PET planet insider Vol. 16 No. 06/15 www.petpla.net New technology of online mineral-adding A new generation of inline mineral-adding technology developed by Newamstar has recently been approved by Coca-Cola. The assessment process included testing the quality of the water four hours after minerals were added. Newamstar says that Coca-Cola’s approval rec- ognises that it has reached an advanced, global level in mineral water production. Accumulating knowledge, overcoming challenges Newamstar has years of experi- ence in water production, but the addi- tion of minerals was a new subject when it began this project in early 2013. The company assessed vari- ous different kinds of mineral-adding technology as it sought to build understanding. After several rounds of discussion, testing and development, Newamstar designed the systems shown in f g.1. The design then underwent a laboratory test to determine whether the conductivity of mineral salts at different concentrations has a linear functional relationship. The conclusion was that this is indeed the case, as shown in f g. 2. Newamstar maintains that the big- gest advantage of its inline mineral-add- ing technology over traditional methods is that material flow and mineral adding quantity is stable and well mixed, and that very small adjustments can be achieved and slight variations can be identified by the flow detector and con- ductivity meter. The operator needs only to turn the valve in order to dissolve the main mineral agent every 6-8 hours. It is well-known that pure water becomes progressively darker as more and more ink is added to it. Even just a drop will affect the purity and con- centration of the liquid and Newamstar says that its mineral-adding technol- ogy is the same. Mineral concentration must be precisely controlled during the design process as just a single excess drop may lead to the required product concentration being exceeded. It is therefore vital that every drop of product is controlled and the right mixture is maintained. Newamstar says that good prod- ucts must satisfy customers and help them to increase efficiency, while delivering benefits in terms of safe and sustainable production. After complet- ing the Coca-Cola project the company installed a two mineral water production line for Panpan group. As living standards continue to increase, the environment and healthy lifestyles rise in importance. Drinking water is closely identified with a healthy lifestyle and mineral water improves people’s acceptance of water generally. Newamstar asserts that progressively more consumers are going to enjoy the convenience in their healthy drinks that are brought by its advanced technology. www.newamstar.com RO tank supercharge pump f owmeter pipeline mixer conductivity meter mixing tank water supply metering pump premix tank factitial mixing conductivity meter Fig 1: Dosing and regulator f ow- meter (RO water) set to adjust the dosage of metering pump (mother liquor).
