Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
How a hot tub stacks up against taking a cold plunge — and what a new study says about the benefits of doing water therapy after a workout.
Swimming pools using chlorine have been found to contain trihalomethanes, although generally they are below current EU standard for drinking water (100 micrograms per litre). [4] Concentrations of trihalomethanes (mainly chloroform) of up to 0.43 ppm have been measured. [5]
Chloramination is the treatment of drinking water with a chloramine disinfectant. [1] Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants.
A potentially lower cost alternative to using iodine-based water purification tablets is the use of iodine crystals, although there are serious risks of acute iodine toxicity if preparation and dilution are not measured with some accuracy.

The hot tub pump and hot tub heater represent most of the power consumption in a hot tub and vary in use of power depending on their size. [ 4 ] Energy efficiency of portable hot tubs has been studied by the Pacific Gas and Electric Company (PGEC) , [ 5 ] leading to industry responses [ 6 ] and interest from both the California Energy ...
