By popular demand - A quick review of
Popular Chlorination options
Chlorine (or alternative) is a mainstay of any responsible treatment program, and is here to stay! Even if you use a wide variety of supplemental treatment options, you still need to provide some form of chlorination to comply with state and national health codes, prevent Cholera and other nasty issues, and assure a safe and appealing pool water for your patrons and guests.
Per your request here is a quick review of all the popular alternatives along with some positive and negatives:
Sodium Hypochlorite: Popular in the 1980’s as an alternative to gas, it is a prevalent form of chlorination, but the use is on a downward trend. Depending on your fill water, it can be used with Co2 or Acid pH feed systems. The cost varies widely with the size of the deliveries, and your location, but costs less per pound than all other alternatives. Issues include feeder maintenance, heavy dependence on pH correction, and does not address all the other chemicals that need to be added in order to prevent aggressive water from destroying your pool finish and heaters, etc. Pool water must be dumped to avoid salty taste and some irritation.
Calcium Hypochlorite: The Pulsar brand has been around for 25 years, and is a popular All-In-One solution, providing all the Chlorine, Calcium, Bicarb, and even some stain prevention in a self-shocking feeder. Tablets are convenient, and can resolve some on site delivery and storage issues. Tablets cost more but it uses 1/10th the acid of some bleach, and provides savings over required adding of all the other chemicals, and the water quality is great. 2018 Feeders are now self cleaning, and easy to operate, so this is a rising alternative among pools of all sizes.
Trichlor Tablets: Was prevalent in the 1980’s, especially on smaller commercial pools. Tablets are convenient, but it has
fallen out of favor since it leads to quick and continual over-stabilization, and requires you to continually dump your pool water. Cannot meet CDC guidelines for fecal accidents >16 PPM, so dumping most of the pool water
after any accident becomes a major science project. Alkalinity reduction requires constant addition of Bicarb, so this is rapidly falling off the radar.
Saline Chlorination: Many folks seem to love the “mineral pool” feel. Wildly popular on residential pools and totally butchered on many earlier commercial applications. CES has a solid 12-year track record with 100% success rate, but it requires a serious installation of institutional-grade equipment, automatic control of pool water salinity, good service and a knowledgeable approach. It is normally self-funding with quick payback, and the reaction chambers last 3-4 years, so it's a viable long term alternative. Best used with redundant cal-hypo feeder to provide the most cost effective installation cost, and guaranteed performance regardless of bather load or weather.
Nex-Gen: This unique skid mounted package makes Chlorine out recycled pool water. Wheel it in, plug it in, and make your own. Unlike saline, the salt is not added to the pool but is added to the process, so the pool salinity does not really provide the “mineral pool” experience. Popular with stainless pool applications, and can treat multiple pools with one feeder. This self funding alternative often incorporates a redundant feeder for quickest payback, and the popularity is on the rise.
Supplemental Oxidation: Most popular types include Amalgam UV, Medium Pressure UV, and Ozone.. or combinations thereof. Quicker and better than Chlorine in killing some undesirable organisms, but still requires the use of some form of chlorination. Constitutes a pool modification, which means engineering, permits, etc, and requires annual maintenance and periodic lamp replacements, or it will cease to work.
Fortunately, CES has accumulated 35 years of experience in all the above, so we can help you make an educated chlorination decision based on YOUR preference, not ours.
