產品名稱: 污泥毛細吸水時間測試儀\CST測定儀

型號系列:304M CST

品牌:Triton

產地:英國












英國Triton 304M CST是 英國Triton 165 型 CST 的替代品，現(xiàn)在是基本的實驗室 CST 測試設備。電子設備得到了改進，機械計數(shù)器被 LCD 取代。它的設計和測試符合歐洲和美國 EMC 標準。
主輸入電源可以設置為歐洲或美國標準。







自 1970 年代以來，毛細管吸入時間 (CST) 一直被用作表征污泥過濾性和調節(jié)性的快速可靠的方法。污泥過濾性主要控制幾乎所有各種類型的脫水設備的輸出，包括：干燥床、帶式壓濾機、真空過濾器、壓濾機和離心機。標準濾紙產生的毛細吸水壓力用于從污泥中“吸”水。水通過濾紙的滲透率取決于污泥的狀況和濾紙上形成的濾餅的可過濾性。CST 是從與漏斗相距標準間隔放置的兩個電極獲得的。水鋒在這兩個電極之間通過的時間構成了 CST。

Triton 304M CST污泥毛細時間測試儀標配：
CST主機  1臺
有機玻璃塊組件  1套
不銹鋼漏斗  2個
過濾紙  1盒（1盒200張）


主機尺寸約：22 x 16 x 7cm



毛細吸水時間知識擴展：
毛細吸水時間(CapillarySuctionTime，簡稱CST)的測試是表現(xiàn)污泥脫水性能的一個快速和可靠的方法。CST愈大，污泥的脫水性能愈差，反之脫水性能愈好。通過標準濾紙產生的毛細吸水壓力用于從污泥中“吸收”水分，水分滲入濾紙的速率的改變依靠污泥的狀態(tài)和在濾紙上形成的紙餅的過濾性，CST是從漏斗上的兩個以標準間隔放置的電極上獲取。得到的從開始到通過這兩個電極間的時間即為CST。 

污泥毛細管吸水時間（CST）：簡單來說就是污泥與濾池接觸時，在毛細管作用下，污泥中的水分會在濾紙上滲透，在濾池上滲透1cm長度的時間就是CST，單位是秒。CST越大，則脫水性能越差；

英文原文：

The Model 304M CST is a replacement for the Model 165 CST and is now the basic laboratory CST test equipment. Electronics have been improved and the mechanical counter replaced with an LCD. It is designed and tested to comply with European and USA EMC standards.
The mains input supply can be set for either European or USA standards.

Capillary Suction Time (CST) has been used since the 1970s as a quick and reliable method of characterising sludge filterability and conditionability. It is sludge filterability that, predominantly, governs the output of nearly all various types of 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. 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, as long as there is sufficient to generate the CST.

Each Type 304 CST comes with:
CST Meter
Perspex Block Assembly
Stainless-Steel Funnels
Filter Papers (200 with 304M and 20 with 304B)
