6-Stage RO Water Filter with DI & UV Purification

A RODI system cost varies based on production capacity, number of treatment stages, installation requirements, and whether UV purification is included. Residential under-sink systems are typically less complex than commercial or industrial RODI setups. Aqua General begins with water testing and a site evaluation so the recommended system matches your water conditions, usage volume, purity goals, and maintenance needs.

A 6-stage RO system usually combines sediment filtration, carbon filtration, reverse osmosis membrane separation, deionization, polishing filtration, and UV purification. Each stage targets a different water quality concern, including particulates, chlorine or chloramine, dissolved solids, metals, taste and odor, and microbial contaminants. The exact configuration should be matched to your tested water conditions.

DI, or deionization, is used when very low dissolved mineral content is required. After reverse osmosis removes a large percentage of dissolved solids, DI resin further reduces remaining ions for higher-purity water. This can be especially valuable for laboratories, manufacturing, aquariums, dental offices, ice production, and other uses where standard drinking water filtration is not enough.

UV purification uses properly applied ultraviolet light to inactivate microbes, including bacteria, viruses, and other pathogens. It does not add chemicals or change the taste of water. UV works best when installed after filtration because sediment, turbidity, or scale can reduce UV exposure. That is why system design and routine lamp maintenance are important.

Filter replacement frequency depends on water quality, usage, system size, and the specific cartridges installed. Sediment and carbon filters are usually replaced more often than membranes, DI resin, or UV lamps. Aqua General services a wide range of RO and water treatment brands and maintains replacement parts for routine maintenance, helping keep systems operating reliably.

Yes. Aqua General provides residential, commercial, and industrial water treatment solutions, including reverse osmosis, DI water systems, UV purification, and custom-designed filtration. Commercial applications may include offices, restaurants, hotels, manufacturing facilities, beverage operations, ice makers, medical offices, and dental practices. System capacity and pretreatment are selected based on actual demand and water conditions.

Aqua General offers free on-site water analysis to evaluate water quality before recommending equipment. Testing helps identify concerns such as hardness, chlorine, chloramine, metals, dissolved solids, and other treatment needs. This allows the team to recommend the right combination of reverse osmosis, DI, UV, carbon, softening, or custom filtration rather than guessing.

Aqua General services Brazoria County, Fort Bend County, Galveston County, Harris County, Montgomery County, the Greater Houston metropolitan area, and partial coverage in Chambers, Waller, and Wharton Counties. Because some counties have partial coverage, it is best to confirm your address when scheduling water analysis, installation, repair, or maintenance.
