Iron remove filter sand filter coal filter for sewage treatment plants

Haiyuan water treatment team supply deferrization filters charcoal filter solution for Belarus.

Please check below client met question and we solution for deferrization filters charcoal filter.

Customers from Belarus need to deal with iron and other impurities in treated waste water. and it needs advanced treatment before entering ultrafiltration and reverse osmosis unit. Because ultrafiltration and reverse osmosis equipment have higher requirements on the quality of influent water.

Below is client requirement and waste water parameter:

Can you pick us up sand+coal filters for the metallurgical industry? I enclose the values in the wastewater that we are going to finish cleaning:

pH - 5.9-7.4

Total dissolved solids (TDS) - about 13100 mg/dm3

Suspended solids - 205.7 mg/dm3

Chloride ion (Cl-) - 700-800 mg/dm3

Sulfate ion (SO₄²-) - 1650-2750 mg/dm3

Total iron (Fe)- 3.5-135

These are the values for two days of observation of wastewater.

20m3/hour of wastewater.

Needed with the function of washing by time and pressure (with manometers), also need two pumps - one for supply, the second for backwashing (will be carried out by hot water).

According to our experience, the difference between 3mg and 150mg of iron content in sewage after treatment is too large. There are two possibilities. One is that the process of iron treatment in sewage treatment is unstable, and the other is that there is an error in analysis. Because they only measured the water quality at intervals of two days with a difference of 50 times.

 Iron remove filter sand filter coal filter as for ultrafiltraion and reverse osmosis pretreatment filter.

After we discuss more detail we supplied below solution(Black is client. Blue is us)

Do I understand correctly, if iron content will be up to 3 mg/L - in that case will need 2 filters - sand and carbon, if iron content will be 6 mg/L - will need more? 3 or 4 filters? 

----- if iron content will be up to 3 mg/L and 6mg/L. Both of them need  2 pcs iron remove filter(site need one tank, add air into the tank,means aerator, meanwhile add two iron removal filters) . and also need the sand filter, coal filter. total 4 filters.

If 3mg/L iron means 4-5 days  wash media. if 6mg/L iron maybe 2-3 days wash media. 

When reduce wash medial then can help use reduce the clean water.
