【正文】 tc. RO system include: RO protective filter, highpressure pump, RO units, RO cleaning system, control instrument, etc. 過濾器系統(tǒng)包括:砂過濾器、砂過濾器反洗系統(tǒng)、控制儀表等; 活性炭過濾器系統(tǒng)包括:活性炭過濾器、活性炭過濾器反沖洗系統(tǒng)、控制儀表等; 反滲透系統(tǒng)包括:保安過 濾器、高壓泵、反滲透膜組、反滲透清洗系統(tǒng)和控二級反滲透產(chǎn)水箱 二級反滲透產(chǎn)水箱 10t/h 脫鹽水系統(tǒng) 12 制儀表等。 由于,反滲透是比較精密的水處理系統(tǒng),原水只有經(jīng)過合理、可靠的預處理,才能不對反滲透系統(tǒng)造 成污染或?qū)⑽廴境潭冉档阶畹停瑥亩芎玫谋Wo了核心除鹽系統(tǒng),延長反滲透膜的使用壽命,大大降低運行成本和維護成本,因此,為本系統(tǒng)配置先進、可靠的預處理工藝:砂過濾器+活性炭過濾器。依據(jù)業(yè)主提供水質(zhì)報告及業(yè)主對本系統(tǒng)的要求,本系統(tǒng)采用我公司設計制造的砂過濾器 +活性炭過濾器作為預處理設備,設備運行穩(wěn)定,抗沖擊負荷 能力強,除鹽采用穩(wěn)定、可靠的反滲透技術,技術先進可靠,保證了產(chǎn)水質(zhì)量。 Pressure Parts ( 1) GB150 ( 2) ASME ( 3) Supervision regulation on safety technology for pressure vessel Materials ( 1) ASTM ( 2) ASME ( 3) Chinese Standard Piping/Flange ( 1) HG 2055393 (Pipes) ( 2) HG 20592~20635 (Flange, bolts, nuts, gaskets, etc) 制造及材料應符合下列標準和規(guī)程的最新版本的要求。 除鹽水水質(zhì)標準按照 GB/T 6682《 分析實驗室用水規(guī)格和試驗方法 》 中的三級用水標準。 三、 Technical guarantee 技術保證 Pretreatment system 預處 理系統(tǒng) Outlet SDI產(chǎn)水 SDI: 4 Turbidity 濁 度: 1NTU Recovery Rate 水的回收率: 95% Water production 設備產(chǎn)水量: ≥ Quantity 設備套數(shù): 1 套 1st pass RO system 一級 RO 系統(tǒng) 1st pass RO desalination rate 一級 RO 脫鹽率 : 10t/h 脫鹽水系統(tǒng) 6 ≥98%( within 1 year 一年) ≥95%( within 3 years 三年) Recovery of 1st pass RO system 一級 RO 系統(tǒng)回收率: ≥75% Water production 產(chǎn)水量: ≥11t/h Output water conductivity 產(chǎn)水電導率 : ≤10181。 Sand filter can reduce the turbidity, and active carbon filter shall absorb the residual turbidity and anic matters to make sure the pretreated water satisfy RO set where the water will be desalted and eligible water is produced. PLC control is used for whole system. DP interface is included and autocontrol, distance inspection DCS will be relized. 砂過濾器可以降低水中濁度,活性炭過濾器可以進一步吸附水中懸浮物質(zhì)和有機物,使產(chǎn)水達到反滲透的進水要求,反滲透為脫鹽系統(tǒng),確保出水水質(zhì)達標。 The raw water is municipal tap water. The water quality is detailed in sheet 1: raw water quality. The totally output of desalt water will be 10t/h. According to raw water quality and Requisition requirement, the main process of DI system is ensured as below: Quartz sand fiter+active carbon filter+two pass sand fiter, active carbon filter, two pass RO are main advance, safety and reliable running, wateramp。 0 Tenderee: 招 標人: AGENCY: 招 標代理機構:北京 ****工程技術有限公司 Bidding project: Project 招 標項目: Project Biding equipment: equipments for 10t/h desalted water system 招 標設備: 10t/h 脫 鹽水 系統(tǒng)設備 Biding number: 招 標編號: Bid Documents Technical Part 投標文件 技術部分 September, 2020 2020 年 9 月 10t/h 脫鹽水系統(tǒng) 1 Contents 目錄 一、 General 項目概述 ........................................................................................... 2 二、 Utility Data 共用工程條件 ............................................................................. 4 三、 Technical guarantee 技術保證 .................................................................. 5 四、 Design amp。 **** is trusted by **** (Huizhou) LTD to carriy out works of this 10t/h desalted water system to supply eligible DI water for industry production. 本項目是北京 ****工程技術有限公司 受 ****有限公司 的委托,承擔本 10t/h 脫鹽水系統(tǒng),主要是為生產(chǎn)提供脫鹽水。整套系統(tǒng)設計以砂過濾器、活性炭過濾器、反滲透為主要處理設備。 Raw water quality 原水水質(zhì) The raw water is municipal tap water.
