ENSURING THE SAFETY OF ADDITIVES USED IN DESALINATION PLANTS TO PRODUCE POTABLE WATER - THE ROLE OF INDEPENDENT APPROVAL AGENCIES AND COMPREHENSIVE TOXICOLOGICAL AND ECOTOXICAL PRODUCT PROFILES

Chemical antiscalants improve the cost effective operation of desalina tion plants thereby improving the quality of life and enhancing the ec onomic prosperity of many regions of the world. However, the adoption of chemical additives to enhance the efficiency of both evaporative an d membrane desalination processes should be carefully managed to ensur e that full account is taken of their toxicological and ecotoxicologic al profiles. Independent approvals e.g, DWI, KIWA and NSF, are a valua ble safeguard to the water-producers that their chosen product will no t cause harm in use. The BELGARD and FLOCON ranges of antiscalants hav e been fully tested and are fully approved by these independent agenci es.
