[collection] operating procedures for MBR membrane cleaning
1、 MBR membrane fouling judgment
On line maintenance and cleaning: it has nothing to do with the pressure difference. Stop filtering regularly (about once a week) and drive the low concentration (300 ~ 500mg / L) solution into the membrane for cleaning.
Online enhanced washing: monitor and manage...

Relationship between pump head and flow? How to calculate the lift? Pure water equipment ultra pure water equipment manufacturer
泵的揚(yáng)程計(jì)算是選擇泵的重要依據(jù)，泵揚(yáng)程與流量的關(guān)系可以參照下面這張圖。
泵揚(yáng)程由管網(wǎng)系統(tǒng)的安裝和操作條件決定，計(jì)算前應(yīng)首先繪制流程草圖，平、立面布置圖，計(jì)算出管線的長(zhǎng)度、管徑及管件型式和數(shù)量。
一般管網(wǎng)如下圖所示
D——排出幾何高度，m；
取值：高于泵入口中心線：為正；低于泵入口中心線：為負(fù)；
S——吸入幾何高度，m；
取值：高于泵入口中心線：為負(fù)；低于泵入口中心線：為正；
Pd、Ps——容器內(nèi)操作壓力，m液柱（表壓）；
取值：以表壓正負(fù)為準(zhǔn)
Hf1——直管阻...
