自20世紀(jì)70年代以來(lái),毛細(xì)管抽吸時(shí)間被用作表征污泥可過(guò)濾性和可條件性的檢測(cè)方法。
污泥可過(guò)濾性是脫水設(shè)備(包括:干化床、帶式壓濾機(jī)、真空過(guò)濾機(jī)、壓濾機(jī)和離心機(jī))的性能。
7*9cm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(guò)濾性。CST是從兩個(gè)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(gè)電極之間經(jīng)過(guò)的時(shí)間構(gòu)成CST。
304B 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(cè)試符合歐洲和美國(guó)的電磁兼容標(biāo)準(zhǔn)。電源輸入可按歐洲或美國(guó)標(biāo)準(zhǔn)設(shè)置。

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.
