美国原装反渗透膜专用阻垢剂11倍超级浓缩液。

SpectraGuard SC反渗透阻垢剂高效控制膜污堵，可同时防止各种无机盐垢，金属垢和胶体所造成的反渗透膜污染，尤其适用于浓水侧硅含量超过300PPM的情况。

SpectraGuard SC反渗透阻垢剂是针对原水中硅的控制而研发的一种超高性能反渗透化学品，它在全面控制各种无机垢类，金属垢和胶体的同时，尤其对原水中含有的较多硅进行阻垢，有效防止其在反渗透膜上的沉积，本产品采用的是具有性的Dendrimer树枝状聚合物技术，其的分子构成确保其与水溶解，在使用时只须按计算加药计量与相应比例的RO产水或经过预处理的净水混合即可，(对于具体RO系统所确定的配药比例，请依据原水的水质情况向相关供应商咨询，一般加药量为3ppm)。

SpectraGuard SC反渗透阻垢剂包装采用的11倍美国原装超级浓缩液，可以为您节约90%运输成本及储存空间，在一般存放条件下，药剂有效期可超过2年(具体储藏和使用条件请参阅相关说明)，标准的11倍超级浓缩液商业包装为5加仑(18.93升/桶)，净重22.7KG，相当于250KG标准液。

不同于传统的含磷阻垢剂，SpectraGuard SC本身没有任何含磷的成分，所以不会向加药箱，输水管和RO系统内部的细菌和微生物提供其生长所需的营养物质，从而消除了会导致膜系统生物污染和细菌超标的一大隐患，也不会导致与水中的金属离子反应生成磷酸盐沉淀而导致的膜元件污堵，SpectraGuard SC在极限的pH及温度环境中也保持稳定。

SpectraGuard SC反渗透阻垢剂使用非常方便，可以在线连续注入反渗透系统，针对不同水质污染情况，本阻垢剂也可以与其它PWT相关产品，例如BioGuard微生物抑制剂按加药比例混合于同一药箱并由一点注入系统，节约加药设备投资，方便操作控制，此外，其的分子结构使其本身对膜十分安全，就算在高浓度下(设备发生故障时，加药过量)也不会在膜上发生任何沉积，结晶式附着而导致膜的污堵。

SpectraGuard SC通过ANSI/NSF Standard 60认证，反渗透饮用水处理系统也可放心使用本产品，从而获得有效保护。

SpectraGuard™
SpectraGuard SC™ Liquid Super Concentrate

SpectraGuard liquid antiscalant/dispersant is a high-performance chemical pretreatment that controls inorganic scale, metals and colloids in RO feedwaters. Its unique performance characteristics provide users with complete control over system feedwater chemistry, while reducing membrane scaling tendencies and minimizing membrane cleaning requirements. SpectraGuard is compatible with all membrane types and system components.

SpectraGuard SC is a liquid super-concentrate which provides users the convenience of a 5 gallon (18.9 liter) pail equivalent to a 55 gallon (208.2 liter) drum of standard liquid antiscalant. SpectraGuard SC cuts shipping volume by 90% making it ideal for high-volume users.

SpectraGuard and SpectraGuard SC maintain performance integrity at extreme pH levels and temperatures. These products remain stable in the presence of m*lent ions such as iron. All SpectraGuard products are phosphate-free, and do not contribute to metal precipitation or biological growth in tanks, piping, or the RO.

SpectraGuard is typically dosed into feedwaters at the rate of 2-6 ppm and it may be blended with PWT’s BioGuard ACS™ and OrganoGuard™ products. As a liquid, SpectraGuard is ready to use and may be injected neat, or diluted to accommodate varying system sizes. SpectraGuard is available in 5 gallon (18.9 liter) pails, 55 gallon (208.2 liter) drums, totes, and in bulk.

Both SpectraGuard and SpectraGuard SC comply with ANSI/NSF Standard 60 requirements and may be used on potable water systems.
