Advanced technique, reliable running, energy saving and easy operation are design principle of system. RO is one kind of delicate water treatment equipments. Reliable pretreatment could minimize pollution of membrane system, prolong the RO membrane lifespan and lower the cost for running and maintain cost. It is been proved that process Quartz Sand Filter +Active Carbon Filter can reduce the turbidity effectively and adsorb grain, metal oxidation, colloid, anic pound, bacterium, etc. The outlet water of Quartz Sand Filter +Active Carbon Filter could meet the RO inlet water quality pletely. 為滿足工藝技術(shù)先進、運行穩(wěn)定、節(jié)能環(huán)保、操作方便等設(shè)計原則，采用砂過濾器 +活性炭過濾器作為預處理，反滲透作為除鹽系統(tǒng)，確保達到用水水質(zhì)指標。 Equipments collocation 設(shè)備配置 Raw water tank 原水箱 ： 1 臺 1set Raw water pump 原水泵 ： 2 臺（ 1 用 1 備） 2sets（ one for stand by） Sand filter 砂過濾器： 1 臺 1set Activated carbon filter 活性炭過濾器： 1 臺 1 set Intermediate storage tank 中間水箱 ： 1 座 1 set Coagulant dosing system 混 凝劑加藥系統(tǒng)： 1 套 1 set Bactericide dosing system 殺菌劑加藥系統(tǒng)： 1 套 1 set 10t/h 脫鹽水系統(tǒng) 14 Pipeline mixer 管道混合器： 1 臺 1 set Function description 功能描述 Pretreatment is mainly supposed to improve the qualification of water supply. The optimum pretreatment will reduce the opportunity of RO membrane’s pollution and scale and prolong the RO membrane lifespan. Mechanical impurity, colloid, iron, animalcule, algae and anic pound are the objects to remove by the pretreatment. 預處理系統(tǒng)主要作用是對不符合反滲透膜進水水質(zhì)要求的原水進行處理，改善供水條件，使其達到 反滲透膜的進水要求，減少反滲透膜的污染和結(jié)垢，延長反滲透膜的使用壽命。 混 凝劑加藥系統(tǒng)的作用是向原水中投加適量的混凝劑，將原水中的懸浮物、有機物、膠體等聚集成大的顆粒，以便在砂過濾器中被有效地去除。 ——過濾器的運行周期較長。 過濾流速： 單元過濾流量： 數(shù)量： 1 臺 多路閥： 1 臺 安裝形式：頂裝 （ 5） active carbon filter 活性炭過濾器 Function of active carbon: with a large number of tiny aperture and high specific surface area, active carbon has a strong ability of adsorption. Organic pound, animalcule, colloid, and granules can be adsorbed when the water flow through carbon bed. Active carbon also can adsorb the surplus chlorine and protect the RO membrane from oxidation. The removing of Organic pound and animalcule efficiently prevents the growth of bacteria in the RO membrane and prolongs the cleaning period and lifespan. 10t/h 脫鹽水系統(tǒng) 22 Multiway valve and time are both adopt here as the same as sand filter. The active carbon backwash water will be supplied by the sand filter. When the active carbon filter’s running time has reached the set time, it will be stop to backwash and enter a work state after the backwash automatically. 活性炭的作用：活性炭有非常多的微孔和巨大的比表面積，具有很強的物理吸附能力。 總體過濾面積： 178。本系統(tǒng)選用 BWA 高效的阻垢劑，該藥劑是一種分散型隱蔽劑，其作用如下： ★ 阻垢效能高，不加酸的條件下，原水 LSI 指數(shù)最大允許值為 ，在此范圍內(nèi)可有效的控制無機物結(jié)垢。 一級 RO 高壓泵參數(shù)： 流量： 揚程： 90m 功率： 材質(zhì) ：過流部件 SS316 數(shù)量： 1 臺 二級 RO 高壓泵參數(shù)： 流量： 11t/h 10t/h 脫鹽水系統(tǒng) 30 揚程： 70m 功率： 材質(zhì)：過流部件 SS316 數(shù)量： 1 臺 （ 5） Reverse osmosis set(RO) 反滲透裝置 ⅰ ） RO summarization 反滲透概述 Reverse osmosis， RO： Given high pressure drives the solvent water passing the RO membrane and reached the low pressure side. The other ponents such as salt will be stopped and concentrated in the high pressure side and the division is achieved. Reverse osmosis is a widely and advanced desalt technology. It has a high desalt ability with safety, agility and easy operation. High pressure pumps, RO module, cleaning system and control instruments are included in RO system. 1ST pass RO set parameter： RO water production： 11t/h Recovery of 1st RO system： ≥75% 1st RO desalination rate： ≥98%（ One year） ≥95%（ three years） Amount membranes of single RO set： 15 RO permeated flux： RO membrane brand： GE or equivalent Amount of 1st RO： 1set 2nd pass RO set parameter： RO water production： 10t/h Recovery of 2nd pass RO system： 90% 2nd pass RO desalination
