Abstract

Systems and methods for sanitizing pool/spa water are provided. An electrolytic chlorinator is provided which includes a combined flow, temperature, and salt concentration sensor. The electrolytic chlorinator could include an acid tank for in-situ cleaning of the electrolytic chlorinator or acidification of pool/spa water where needed. A delayed polarity reversal technique is provided for de-scaling and managing passivation of the blades of an electrolytic chlorinator. The electrolytic chlorinator could include a sacrificial anode for protecting components of the chlorinator as well as other pool/spa components. The electrolytic chlorinator could include an integral, electrically-controlled acid generator, a brine tank for periodically superchlorinating and/or shocking pool/spa water, and/or a plurality of chemical tanks/feeds for periodically injecting chemicals into the chlorinator. A combined ultraviolet (UV)/Ozone and salt (electrolytic) chlorine generator is provided, as well as: filters having integral UV sanitizers; reflective linings for UV sanitization systems; means for injecting bubbles into pool/spa water.
