HQQ-5062反渗透专用清洗剂-云南皓泉水处理

 RO系统正常运行维护管理的条件下,每36个月的时间周期,反渗透膜也会被无机物垢、胶体、微生物、金属氧化物等逐步累积污染,因为RO膜的进水水质只能处理控制在一个相对安全的指标范围内,而这些指标越低,RO膜被污染的可能性就越少,受污染的周期就越长;
  这些物质(污染物)沉积在膜表面上引起反渗透装置出力下降或脱盐率下降,不能满足生产用水要求;使膜压差升高,甚至对膜造成不可恢复的机械损伤等;因此,为了恢复良好的透水和除盐性能,保正RO系统运行参数在最合理的区间,必须及时制定针对性的方案对RO膜进行化学清洗;
  用于RO系统的清洗化学品都是相对强酸性或强碱性的,这些配方均为复合型化学品,在清洗中通过复杂的协同综合作用,达到清洗恢复的目的;而清洗液的控制条件都是控制在RO膜能耐受的边缘值,对RO膜和高压泵叶轮等肯定存在一定的损伤;因此,在日常运行中,精细管理使用针对性的日常化学品维护是必须的,有效避免对RO系统的频繁清洗是非常必要的。

一.需要进行清洗的条件
  1.1 RO装置的例行维护,一般正常运行36个月后;
  1.2 RO膜的产水量比正常产水量下降10%~15%;
  1.3 透盐率比正常透盐率上升10%;
  1.4 RO系统的全部或部分膜两侧的压力差上升10%~15%;
  1.5 RO装置长期停用前;
  在正常运行条件下(温度波动小),当发生上述任一条件时,建议对RO膜进行清洗。
二.产品特点
  HQQ-5061/5062专用清洗剂,是专为RO膜设计的高效能复合清洗液配方,用于去除RO膜表面的金属氢氧化物、无机垢(碳酸盐、硫酸盐、硅酸盐、其它化学沉积物等)、有机垢(粘泥、黏液、胶体、藻类等);
它适用于所有的复合RO膜、钠滤膜等,本系列产品能强力溶解清除附着在膜上的各种有机和无机垢,低泡或无泡沫产生,经多套50/小时产水的RO系统使用,其优良的清洗效果,使RO系统安全恢复运行在最合理的参数区间;
本系列产品分为碱性或酸性有机复合型配方,清洗时的参数均控制在RO膜元件要求范围内,对膜无化学损伤。

四.用途说明
  清洗药剂通常的稀释比例是整个清洗系统体积的38%,具体配比需根据个别RO系统装置的实际污染情况,由维邦公司当地售后服务工程师根据现场情况确定最终配比。HQQ-5061主要针对生物垢及胶体污染特别有效;HQQ-5062主要针对金属氧化物、碳酸盐、硫酸盐、硅酸盐、其它化学沉积物、胶体等污染特别有效。
五.使用说明
  5.1 检查清洗回路:清洗罐、软管和保安过滤器已连接好,用除盐水清洗干净,至少冲洗2次。
  5.2 除无机垢及化学垢:用反渗透透过水或除盐水注入清洗罐二分之一体积,将已预算好的
HQQ-5061/5062反渗透清洗药剂缓慢注入到清洗罐,继续注入除盐水至90%体积,用清洗泵循环混合溶液;条件许可,用蒸汽将混合溶液加热到膜制造商所规定的最高温度,可取得更好的清洗效果。
  5.3 按清洗回路,启动清洗泵,开始清洗,最初流出RO膜的清洗液应排放出系统,体积约为清洗罐的1020%,清洗流量、流速应按照膜制造商或系统供应商的推荐值,清洗时间0.52小时,清洗完毕将清洗液直接排放入污水处理站,用除盐水冲洗净清洗容器和回路备用;
  5.4 启动反渗透系统冲洗程序,冲洗RO系统膜表面3060分钟。
  5.5 除有机垢:方法同除无机垢法。
  5.6 对于多段RO系统,每段单独清洗可以获得最大效果。
六.包装与贮存
本品采用25公斤200公斤防盗塑料桶包装,也可根据用户要求包装。本品贮存于干燥通风的库房内,贮存期十个月。
七.注意事项
  本系列产品为一般化学品,不属于特殊危险品,不燃不爆;但原液具有一定的酸性或碱性,接触皮肤可能会引起灼伤,建议在使用时佩戴胶手套,如果药剂直接接触皮肤,请及时用清水冲洗510分钟,如进入眼睛,除用清水冲洗外,应迅速到医务室就诊

HQQ-5062 RO cleaning agent - Yunnan Hao spring deal

 
◆ RO systems up and running in the maintenance and management of the condition, every 3 to 6 months period of time, will also be inorganic fouling of reverse osmosis membranes, colloids, microorganisms, such as the gradual accumulation of pollution, metal oxides, because the RO membrane water quality control can only handle a relatively safe target range, and these indicators, the lower, RO membrane is less possibility of contamination, the longer the period of contamination;
◆ these substances (contaminants) deposited on the membrane surface caused a decrease or reverse osmosis desalination plant output rate of decline, can not meet water requirements; the film pressure increased, even causing irreversible membrane mechanical injury; Therefore, in order good recovery and desalination performance of porous, Yasumasa RO system operating parameters in the most reasonable range, must be timely to develop targeted programs for chemical cleaning of RO membrane;
◆ RO system for cleaning chemicals are all relatively strong acidic or alkaline, these formulas are complex chemicals, the cleaning effect through complex co-synthesis, to restore the purpose of cleaning; and control of cleaning fluid conditions are controlled at the edge of RO membrane can withstand the value of the RO membrane and high pressure pump impeller, etc. There are certainly some damage; Therefore, in daily operation, management and use of fine chemicals targeted routine maintenance is necessary, avoid frequent cleaning of the RO system is necessary.

One. Conditions need to be cleaned
1.1 RO plant routine maintenance, the normal operation after 3 to 6 months;
1.2 RO membrane water yield than the normal water production decreased by 10% to 15%;
1.3 The rate of penetration of salt through the salt than normal rate of increase of 10%;
1.4 RO system, all or part of the pressure difference across the membrane increased by 10% to 15%;
1.5 RO unit stops for long ago;
Under normal operating conditions (temperature fluctuations small), the event any of these conditions, the proposed RO membrane cleaning.
II. Features
HQQ-5061/5062 special cleaning agent, is designed specifically for high-performance RO membrane cleaning liquid compound formulations for the removal of RO membrane surface of the metal hydroxides, inorganic scale (carbonate, sulfate, silicate, and other chemical sediments, etc.), organic fouling (slime, mucus, gel, algae, etc.);
It applies to all composite RO membrane, membrane sodium, etc. This series of products to remove dissolved strongly attached to the membrane of various organic and inorganic scale, low-foam or no foam, after several sets of 50 tons / hour capacity of water RO systems, and its excellent cleaning effect, the RO system security recovery operation in the most reasonable range of parameters;
This series is divided into basic or acidic organic compound formula, cleaning parameters are controlled within the requirements of RO membrane elements, on the membrane without chemical damage.
