A membrane separation pretreatment apparatus including a membrane separation unit and a first underwater plasma discharge unit disposed in front of the membrane separation unit is provided. The membrane separation pretreatment apparatus includes a membrane separation unit configured to remove particulate matter contained in raw water, and a first underwater plasma discharge unit disposed in front of the membrane separation unit and configured to cause a portion of the raw water to be introduced into the membrane separation unit to perform underwater plasma discharging.

The method for producing a phospholipid concentrate derived from a liquid dairy composition comprising at least caseins and phospholipids, includes at least the steps of: —passing the dairy composition into an ion-exchange column on a cationic resin, —concentrating the phospholipids of the calcium-depleted dairy composition by means of controlled transmembrane pressure gradient microfiltration, and —recovering the retentate from the microfiltration and obtaining a phospholipid concentrate.

A wastewater treatment system includes a biological treatment plant and an auxiliary, non-biological treatment plant. The auxiliary plant receives overflow, which can be sanitary sewer overflow, combined sewer overflow or strictly storm overflow. Treatment is by coagulation and membrane separation, removing most bacteria. Following treatment the outflow can be discharged to streams.
