remove large debris such as sticks, leaves, trash and other large particles
water stored in reservoirs for periods between a few days and many months to allow natural biological purification to take place
salts are treated with soda-ash (Na2CO3) to precipitate CaCO3 out utilizing the common-ion effect
chlorinated to minimize the growth of fouling organisms on the pipe-work and tanks

역할들에 대해 설명하시오.
우리 몸 속 주요 이온들의 역할
1. K (칼륨, Potassuim) - K⁺
K⁺ 은 세포 내 양이온의 최대 스타!!
K은 체내에서 가장 많은 양이온
근육 내에 대량 존재
