Haiyuan water treatment team suppliy pharmaceutical waste deep treatment solution for belarus

please check below client question and we solution for 350m³/hr big project .

Here are details of our discssion with customers :regarding the 350m³/hr project,at the moment the design of the sewage treatment plant of the metallurgical plant is in progress ,industrial effluent is water after cooling of reactors and is not highly contaminated:

The first stage we plan to put a drum sieve to delay mechanical impurities, and then flotation units (they will significantly reduce the content of suspended solids, petroleum products, COD, BOD, but will add some chlorides/sulfates, depending on the coagulant used).

Approximately after flotation, the content of suspended solids will not exceed 15-20 mg/l, petroleum products less than 1 mg/l, COD, BOD by our experience after flotation are reduced by 5-10 times.

Taking into account the fact that it is necessary to reduce salt content - practically the only option we see RO. However, COD, BOD and suspended solids content after flotation is higher than it is necessary for correct operation of RO, so we consider it necessary to put filtering columns with sand, coal and ion-exchange resin.

Since you have a lot of experience with RO equipment and filter columns, please guide us.

Regarding evaporation, reverse osmosis produces about 10-15% of the total salt concentrate water. We are laying with the reserve - about 45m3 / hr. However, as already mentioned earlier - you have

Then our engineers provide customers with the following process flow chart:

Feed water tank----Feed pump----Quartz sand filter----Activated carbon filter (with backwash pump)----precision filter----pretreatment water tank----1 stage RO booster pump----scale prevention device----precision filter----1 stage high pressure pump----1 stage RO system (CIP)----product water tank (1 section of concentrated water tank)

1 stage concentrated water tank----2 stage high pressure pump----2 stage RO system----product water tank
