Approvals

• NSF International Certifies that this product conforms to the requirements of NSF/ANSI Standard 60 - Drinking Water Treatment Chemicals - Health Effects. Maximum use level according to NSF approval: 15 mg/lit.
• Approved by The Norwegian Food Safety Authority

• Directions for use

  NALFLEET™ RO Scale Control shows excellent performance against the following scale forming compounds: - calcium carbonate- calcium sulphate - barium sulphate - strontium sulphate - calcium fluoride - silica and iron. NALFLEET™ RO Scale Control is used when the silica level in the brine is less than 185 mg/l at a brine pH of 7.5 and temperature 25C (77F). NALFLEET™ RO Scale Control conforms to the requirements of NSF/ANSI Standard 60 - Drinking Water Treatment Chemicals -Health Effects.

  Dosing and Control

  Typical dose rate is 5 to 15mls/m3 flow rate. NALFLEET™ RO Scale Control should be fed continuously to minimize precipitation of scale and fouling of RO and nano-filtration membranes. It is recommended to operate the dosing pump with the highest possible frequency and to adjust the dosage by adjusting the pump stroke to ensure membrane protection. The feed point locations should be as close to the RO membrane as practical but one that ensures good mixing with the feedwater prior to entering the RO system. Typically, this is before the cartridge filters. It is preferred to feed NALFLEET™ RO Scale Control neat via a closed feed system to prevent contamination from foreign material (a closed feed system being defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere, except through normal venting or pressure relief devices). NALFLEET™ RO Scale Control can be diluted using RO permeate (only) following these guidelines: 1. Use RO permeate for dilution. 2. Prepare a fresh antiscalant solution every 3-5 days. 3. Inspect the antiscalant day tank before adding the new solution. If needed, the antiscalant tank should be cleaned prior to filling. 4. Dilution rates up to a factor 10 are typically applied. Dilution factors higher than 10 will require more attention with respect to the condition of the antiscalant tank (cleaning) and preparation of a new solution (every 1-3 days). 5. NaOH can be added to the dilution to increase the pH to 10-11. This is especially recommended for warm environments to prevent bio-growth. NALFLEET™ RO Scale Control dosage is dependent on feedwater chemistry, membrane type, and system operating parameters (e.g. recovery, temperature and pressure).

  使用說明

  NALFLEET™ RO Scale Control 顯示出優異的形狀 ，符合以下規模形成化合物 ：- 碳酸鈣- 硫酸鈣-硫酸鋇- 硫酸鍶- 氟化鈣- 矽和鐵 。當鹽水pH值為7.5且溫度為25℃（77°F）時 ，鹽水中的二氧化矽含量低於185 mg / l時 ，使用NALFLEET™ROScale Control 。NALFLEET™RO Scale Control符合NSF / ANSI標準60 - 飲用要求水處理化學品- 健康影響 。.

  劑量和控製

  典型的劑量率為5至15mls / m3流速 。NALFLEET™RO Scale Control應連續進料 ，以盡量減少RO和納濾膜的結垢和結垢 。建議以盡可能高的頻率操作計量泵，並通過調節泵衝程來調整劑量以確保膜保護 。進料點位置應盡可能靠近RO膜 ，但要確保在進入RO係統之前與給水良好混合 。

  通常 ，這是在濾芯過濾器之前 。優選通過封閉的進料係統進料NALFLEET™RO Scale Control ，以防止異物汙染（封閉的進料係統被定義為一種係統 ，其中流體從封閉的儲存容器移動到處理過的介質中而不暴露於大氣 ，除了通過正常的通風或減壓裝置）

  NALFLEET™ RO Scale Control可使用RO滲透液（僅限）按照以下指南進行稀釋 ：

  1.使用RO滲透液稀釋 。

  2.準備每3-5天一次的阻垢劑溶液 。

  3.在添加新溶液之前 ，檢查防垢劑日罐 。如果需要 ，應在填充前清潔防垢劑罐 。

  4.通常應用高達10倍的稀釋率 。稀釋因子高於10將需要更多關注防垢劑罐的狀況（清潔）和新溶液的製備（每1-3天） 。

  5.可以將NaOH添加到稀釋液中以將pH增加至10-11 。特別推薦在溫暖的環境中使用 ，以防止生物生長 。

  NALFLEET™ RO Scale Control劑量取決於給水化學 ，膜類型和係統操作參數（例如回收率 ，溫度和壓力） 。
