777716 RO SCALE CONTROL 25 LTR

NALFLEET™ RO Scale Control™ is a broad spectrum scale inhibitor for Reverse Osmosis systems. NALFLEET™ RO Scale Control™ 是一种用于反渗透系统的广谱阻垢剂。RO膜的结垢和铁污染将降低每个形状的系统并导致膜的过早更换。RO膜上沉积的沉积物和沈积物会导致渗透质量差，渗透物产量低，计划外停工，水耗增加和能源成本增加。

Product information

This product supersedes product no: PC-191.11R, 777199

Scaling and iron fouling of the RO membranes will reduce system performance and lead to premature membrane replacement. Precipitation of scale and deposits build up on the RO membrane, which leads to poor permeate quality, low permeate production, unscheduled downtime, increased water consumption and increased energy costs.

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 location 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).

使用说明

NALFLEET™ RO Scale Control 显示出优异的形状，符合以下规模形成化合物：- 碳酸钙- 硫酸钙-硫酸钡- 硫酸锶- 氟化钙- 硅和铁。当盐水pH值为7.5且温度为25℃（77°F）时，盐水中的二氧化硅含量低于185 mg / l时，使用NALFLEET™ROScale Control。NALFLEET™RO Scale Control符合NSF / ANSI标准60 - 饮用要求水处理化学品- 健康影响。.

剂量和控制

典型的剂量率为5至15mls / m3流速。NALFLEET™RO Scale Control应连续进料，以尽量减少RO和纳滤膜的结垢和结垢。建议以尽可能高的频率操作计量泵，并通过调节泵冲程来调整剂量以确保膜保护。进料点位置应尽可能靠近RO膜，但要确保在进入RO系统之前与给水良好混合。

通常，这是在滤芯过滤器之前。优选通过封闭的进料系统进料NALFLEET™RO Scale Control，以防止异物污染（封闭的进料系统被定义为一种系统，其中流体从封闭的储存容器移动到处理过的介质中而不暴露于大气，除了通过正常的通风或减压装置）

NALFLEET™ RO Scale Control可使用RO渗透液（仅限）按照以下指南进行稀释：

1.使用RO渗透液稀释。

2.准备每3-5天一次的阻垢剂溶液。

3.在添加新溶液之前，检查防垢剂日罐。如果需要，应在填充前清洁防垢剂罐。

4.通常应用高达10倍的稀释率。稀释因子高于10将需要更多关注防垢剂罐的状况（清洁）和新溶液的制备（每1-3天）。

5.可以将NaOH添加到稀释液中以将pH增加至10-11。特别推荐在温暖的环境中使用，以防止生物生长。

NALFLEET™ RO Scale Control剂量取决于给水化学，膜类型和系统操作参数（例如回收率，温度和压力）。
