HQQ-5062反滲透專用清洗劑-云南皓泉水處理

 RO系統正常運行維護管理的條件下,每36個月的時間周期,反滲透膜也會被無機物垢、膠體、微生物、金屬氧化物等逐步累積污染,因為RO膜的進水水質只能處理控制在一個相對安全的指標范圍內,而這些指標越低,RO膜被污染的可能性就越少,受污染的周期就越長;
  這些物質(污染物)沉積在膜表面上引起反滲透裝置出力下降或脫鹽率下降,不能滿足生產用水要求;使膜壓差升高,甚至對膜造成不可恢復的機械損傷等;因此,為了恢復良好的透水和除鹽性能,保正RO系統運行參數在最合理的區間,必須及時制定針對性的方案對RO膜進行化學清洗;
  用于RO系統的清洗化學品都是相對強酸性或強堿性的,這些配方均為復合型化學品,在清洗中通過復雜的協同綜合作用,達到清洗恢復的目的;而清洗液的控制條件都是控制在RO膜能耐受的邊緣值,對RO膜和高壓泵葉輪等肯定存在一定的損傷;因此,在日常運行中,精細管理使用針對性的日?;肺な潛匭氳?,有效避免對RO系統的頻繁清洗是非常必要的。

一.需要進行清洗的條件
  1.1 RO裝置的例行維護,一般正常運行36個月后;
  1.2 RO膜的產水量比正常產水量下降10%~15%;
  1.3 透鹽率比正常透鹽率上升10%;
  1.4 RO系統的全部或部分膜兩側的壓力差上升10%~15%;
  1.5 RO裝置長期停用前;
  在正常運行條件下(溫度波動?。?,當發生上述任一條件時,建議對RO膜進行清洗。
二.產品特點
  HQQ-5061/5062專用清洗劑,是專為RO膜設計的高效能復合清洗液配方,用于去除RO膜表面的金屬氫氧化物、無機垢(碳酸鹽、硫酸鹽、硅酸鹽、其它化學沉積物等)、有機垢(粘泥、黏液、膠體、藻類等);
它適用于所有的復合RO膜、鈉濾膜等,本系列產品能強力溶解清除附著在膜上的各種有機和無機垢,低泡或無泡沫產生,經多套50/小時產水的RO系統使用,其優良的清洗效果,使RO系統安全恢復運行在最合理的參數區間;
本系列產品分為堿性或酸性有機復合型配方,清洗時的參數均控制在RO膜元件要求范圍內,對膜無化學損傷。

四.用途說明
  清洗藥劑通常的稀釋比例是整個清洗系統體積的38%,具體配比需根據個別RO系統裝置的實際污染情況,由維邦公司當地售后服務工程師根據現場情況確定最終配比。HQQ-5061主要針對生物垢及膠體污染特別有效;HQQ-5062主要針對金屬氧化物、碳酸鹽、硫酸鹽、硅酸鹽、其它化學沉積物、膠體等污染特別有效。
五.使用說明
  5.1 檢查清洗回路:清洗罐、軟管和保安過濾器已連接好,用除鹽水清洗干凈,至少沖洗2次。
  5.2 除無機垢及化學垢:用反滲透透過水或除鹽水注入清洗罐二分之一體積,將已預算好的
HQQ-5061/5062反滲透清洗藥劑緩慢注入到清洗罐,繼續注入除鹽水至90%體積,用清洗泵循環混合溶液;條件許可,用蒸汽將混合溶液加熱到膜制造商所規定的最高溫度,可取得更好的清洗效果。
  5.3 按清洗回路,啟動清洗泵,開始清洗,最初流出RO膜的清洗液應排放出系統,體積約為清洗罐的1020%,清洗流量、流速應按照膜制造商或系統供應商的推薦值,清洗時間0.52小時,清洗完畢將清洗液直接排放入污水處理站,用除鹽水沖洗凈清洗容器和回路備用;
  5.4 啟動反滲透系統沖洗程序,沖洗RO系統膜表面3060分鐘。
  5.5 除有機垢:方法同除無機垢法。
  5.6 對于多段RO系統,每段單獨清洗可以獲得最大效果。
六.包裝與貯存
本品采用25公斤200公斤防盜塑料桶包裝,也可根據用戶要求包裝。本品貯存于干燥通風的庫房內,貯存期十個月。
七.注意事項
  本系列產品為一般化學品,不屬于特殊危險品,不燃不爆;但原液具有一定的酸性或堿性,接觸皮膚可能會引起灼傷,建議在使用時佩戴膠手套,如果藥劑直接接觸皮膚,請及時用清水沖洗510分鐘,如進入眼睛,除用清水沖洗外,應迅速到醫務室就診

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.
