Water treatment plant in swimming pool processes

Keeping indoor and outdoor swimming pool water clean – so that you can enjoy a beautifully clear bathing experience – requires several important process steps to maintain the water quality both before and during use. There are two key steps here: 1. Preparing the raw water for use in public pools; 2. Continuously pumping the water in the swimming pool through a circuit and thereby cleaning it to maintain its quality and keep it free of contaminants/germs that could potentially cause illnesses.
