Reverse osmosis system NatureWater RO50-NP35 Review

Five-stage membrane water purification plants of the NW-RO50 seriesDesigned for the preparation of ultrapure drinking water from tap water or any other treated water by reverse osmosis. System performance: up to 190l/day. The post-treatment system can be used both independently and as the last step as part of water treatment. The quality of the source water must meet operational requirements. Modifications: • Standard - RO 50-NP35 5 stages. • With booster pump RO 50-A1 5 stages. The system includes: a five-stage (four-stage) filtration unit, a 11.6 l storage tank, a tap, pipes and fittings for connecting to the water supply and sewerage. Technical characteristics of NW-RO50-NP35: • Membrane type: TFC-50, TFM-50 • Productivity, l/day*): 190. • Number of cleaning steps: 5. • Storage tank capacity, l: 11.6. • System membrane flushing: manual. • Water pressure, bar**): 3.5-5.0. • Water temperature, °С: 4-42. • Degree of purification from mechanical, biological and chemical contaminants: 97-99%.• Degree of purification in terms of chlorine and residual odors: at least 90%.* - Specified performance at a pressure of 4.1 bar, temperature 24°C, salinity - 600 mg/l. Capacity may change as the water supply to the system changes.** - Higher values ​​require a pressure reducer to be installed prior to installation. Terms of replacement of filter elements for systems NW-RO50-A1, NW-RO50-NP35. • Mechanical filter (type FA, PD, P, CP, ECP, RB, WP, PPF, STP, PP): 3-6 months. • Carbon pre-filter (type CA, GAC, CC, EP, EPM, C1, PFC, CTO) 3-6 months • Membrane (type TFM, TFC): 24-36 months • Carbon IN-Line post-filter (type T33A, T33B, T33D, IC, GS-10RO, GS-10CAL, MB-10): 12 months Description of work: 1 stage (mechanical cleaning). Cartridge of preliminary mechanical cleaning of 5 microns. Performs the function of protecting the reverse osmosis membrane from mechanical impurities (sand, scale, rust, suspensions). Stage 2 (water treatment with activated carbon). Carbon cartridge installed to protect the membrane from free chlorine and remove organic compounds and microorganisms. Stage 3 (water treatment with activated carbon). The second carbon cartridge is installed for water purification. Served further on the membrane from residual organic impurities, organochlorine compounds and microorganisms. Stage 4 (main cleaning). The main element of water purification is a reverse osmosis membrane. The flow of water supplied to the membrane is divided into permeate (purified demineralized water) and concentrate (brine with impurities). Pure water accumulates in a membrane tank, the concentrate is discharged into the drain. The storage tank with a total capacity of 11.6 liters accumulates a reserve of purified water to ensure comfortable water intake. Stage 5 (finishing with activated carbon). In-Line flow cartridge with granular activated carbon from coconut shell is installed between the accumulator
