英國Triton 304M污泥毛細(xì)吸水時間測試儀CST
自20世紀(jì)70年代以來,毛細(xì)管抽吸時間一直被用作表征污泥可過濾性和可條件性的快速可靠方法。
污泥可過濾性是幾乎所有脫水設(shè)備(包括:干化床、帶式壓濾機(jī)、真空過濾機(jī)、壓濾機(jī)和離心機(jī))的主要性能。
標(biāo)準(zhǔn)濾紙產(chǎn)生的毛細(xì)抽吸壓力用于從污泥中“吸”水。水滲透濾紙的速度取決于污泥的狀況和濾紙上形成的濾餅的可過濾性。CST是從兩個電極上獲得的,電極與漏斗之間的距離為標(biāo)準(zhǔn)距離。水流在這兩個電極之間經(jīng)過的時間構(gòu)成CST。
毛細(xì)吸力產(chǎn)生的力遠(yuǎn)大于漏斗內(nèi)的靜水壓頭,因此只要有足夠的壓力產(chǎn)生CST,試驗(yàn)就與試驗(yàn)污泥量無關(guān)。每次測試都可以在幾分鐘內(nèi)完成。
型號304M CST是型號165CST的替代品。改進(jìn)了電子設(shè)備,用液晶顯示器代替了機(jī)械計(jì)數(shù)器。該裝置的設(shè)計(jì)和測試符合歐洲和美國的電磁兼容標(biāo)準(zhǔn)。
電源輸入電源可按歐洲或美國標(biāo)準(zhǔn)設(shè)置。這個單元現(xiàn)在是基本的實(shí)驗(yàn)室CST測試設(shè)備。

英文介紹
The capillary Suction Time has been used since the 1970's as a quick and reliable method for characterising sludge filterability and conditionability.
It is sludge filterability that predominantly governs the output of nearly all dewatering equipment including: drying beds, belt press, vacuum filters, filter presses and centrifuges.
The capillary suction pressure generated by standard filter paper is used to "suck" water from the sludge. The rate at which water permeates through the filter paper varies depending on the condition of the sludge and the filterability of the cake formed on the filter paper. The CST is obtained from two electrodes placed at a standard interval from the funnel. The time taken for the water front to pass between these two electrodes constitutes the CST.
The force generated by capillary suction is much greater than the hydrostatic head within the funnel, so the test is independent of the amount of sludge tested, as long as there is sufficient to generate the CST. Each test can be completed in a few minutes.
The model 304M CST is a replacement for the model 165CST. The lectronics has been improved and the mechanical counter replaced by a LCD. The unit has been designed and tested to comply with European and USA EMC standards.
The mains input supply can be set for either European or USA standards. This unit is now the basic laboratory CST test equipment.
