PROCESS FOR OBTAINING (REALIZING AND MAINTAINING) WATER BODY LARGER THAN 15,000 M3 FOR USE AT LOW COST IN RECREATION CHARACTERIZED BY THE SAME COLOR, TRANSPARENCY AND CLEANNESS AS SWIMMING POOL OR TROPICAL SEA

摘要

PPROBLEM TO BE SOLVED: To provide the process of obtaining (realizing and maintaining) water body larger than 15,000 mSP3/SPfor use at low cost in recreation characterized by the same color, transparency and cleanness as swimming pool or tropical sea. PSOLUTION: In this process, a water body larger than 15,000 mSP3/SPfor use at low cost in recreation having excellent color, transparency, and cleanness properties, for example, a lake or an artificial lagoon is obtained and maintained. The process comprises the step of providing a structure with a skimmer, which can contain a water body larger than 15,000 mSP3/SP, and a step of feeding an inlet water having iron and manganese levels of less than 1.5 ppm and having a turbidity of less than 5 NTU into the structure in the step (a).
