Abstract
A formulation of cleaning fluid for ultrafiltration membrane adopts mixing compounding technology, and has the components as follows: deionized water as matrix of the cleaning fluid 70%-95%, sodium hydroxide 0.1%-5%, and buffer solution 1%-5%. The formulation of cleaning fluid for ultrafiltration membrane provided by the invention has the advantages of low-cost and easily-obtained chemicals, has broad-spectrum removal effect for pollutants, obvious effect, and good recovery effect for the water flux of the membrane.
Description
Technical field
The present invention relates to a kind of milipore filter cleaning fluid, belong to the Chemical cleaning field.
Background technology
The ultrafiltration membrane washing generally uses the mixed liquor of deionized water and acid or alkali as the cleaning fluid of milipore filter.Although these are cheap and easy to get, but their cleaning performance is not fully up to expectations, the recovery of membrane flux is very restricted, simultaneously, pollution cleaning performance for the profound level of film is also not satisfactory, particularly admittedly contains the stifled especially effect extreme difference of dirt that deposition and the chemical precipitation of thing on the film surface causes for height.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-efficiency washing ability that has, milipore filter cleaning fluid cheap and easy to get, easy to use.
The present invention is by the following technical solutions:
A kind of milipore filter cleaning fluid prescription adopts and mixes compounded technology, and its component and content are:
The base material deionized water 70%-95% of cleaning fluid
NaOH 0.1%-5%
Buffer solution 1%-5%
A kind of milipore filter cleaning fluid prescription adopts and mixes compounded technology, and its component and content are: the base material deionized water 70%-95% of cleaning fluid
Citric acid 0.1%-5%,
Buffer solution 1%-5%
Deionized water is the base material of cleaning fluid; Acid or alkali are the main components of cleaning fluid, determine with acid or with what of alkali and consumption depending on the character of pollutant; The effect of buffer solution is the complexing pollutant, makes pollutant easier by the dissolving of acid or alkali and remove.
The invention has the advantages that medicine is cheap and easy to get, pollutant is had the broad spectrum activity removal effect, and effect is remarkable, good to the water flux recovery effects of film.
