水中的懸浮物質(zhì)是顆粒直徑約在10-4mm以上的微粒，肉眼可見這些微粒主要由泥沙、粘土、原生物、藻類、細(xì)菌、病毒、以及高分子有機(jī)物等組成，常常浮于水流中導(dǎo)致水質(zhì)渾濁。
前過(guò)濾系列利用石英砂、無(wú)煙煤濾料、錳砂等不同介質(zhì)及濾材，配合專用過(guò)濾設(shè)備，可將原水中的所有微粒、懸浮物、能見之沉淀物及泥垢過(guò)濾。系統(tǒng)配置完善的保護(hù)裝置和監(jiān)測(cè)儀表,且具有反沖洗功能，泥垢等污染物很快被沖走，耗水量少，具全自動(dòng)功能。

The particle diameter is about 10-4mm or more. it is visible by eyes .these particles mainly included silt, clay, protozoa, algae, bacteria, viruses, and high composed of organic molecules, often floating in the water to make the water turbid.

The pre-filters can remove sedimentp ,particles and suspended solids in the feed water , by using quartz sand, anthracite filter media, mult-media and manganese sａnd filter with special filter elements. System provide protection devices and monitoring instruments, and also have backwashing function ,will remove dirt and other pollutants, small consumption, automatic operation .

活性碳過(guò)濾器

Actived carbon

活性碳過(guò)濾器能有效地清除

Activated carbon filters can effectively remove :

● 水中的水生動(dòng)物、植物或微生物的繁殖和腐爛而發(fā)出的魚腥氣味及霉?fàn)€氣味。
● 水中的有機(jī)物質(zhì)的分解而散發(fā)的泥土氣味或澀味。
● 水中熔解氣體如SO2、H2S、及NH3的臭味。
● 排入水中的工業(yè)廢水所含雜質(zhì)如石油、酚類等臭味。
● 消毒水過(guò)程中加入氯氣等氣味。

●anabaena ,rotten smell and breed of aquatic animals , plants and microbe.

●soil smell or astringency of water ,as a reason of organic matter corruption .

●odor of smell of gas dissolved in water，such as SO2, H2S, and NH3.

●odor of industrial wastewater discharged into the water.

●odor when it add chlorine in the disinfect process.

基特點(diǎn)是吸收力強(qiáng)，碳粒表面有很多肉眼看不到的小孔、能將水中的各種嗅味、色素、有機(jī)物體及余氯吸掉，經(jīng)過(guò)濾后水質(zhì)便會(huì)無(wú)色、無(wú)味、無(wú)嗅、清澈非常。

Its basic features is strong absorption and has a lot of invisible holes in the soot surface, can remove variety of odor, pigment, organic maters ａnd chlorine in water. After treatment, through the filtered it would be colorless ,no smell ,no odor and very clear .

精密過(guò)濾器

Precision filter

精密過(guò)濾器為各種精度的濾芯組成，一般使用1～3個(gè)月左右或進(jìn)出水壓力差值（P2-P3）大于0.1MPa時(shí)更換，目的是截留液體的雜質(zhì)和顆粒，確保預(yù)處理效果，使反滲透膜免于被顆粒，懸浮物損壞。

The precision filter was consist of a variety of precision filter ,it was replace when use 1- 3 months or water pressure is more than 0.1MPa ,the purpose is to retain impurities in the liquidand particles and ensure pretreatment effect ,to avoid damage of reverse osmosis membrane from particles , suspended matter
