A device is provided for increasing the pH of an acidic aqueous stream, which may result from commercial activity in petroleum, mining, metal finishing and food processing sectors, among others. A container defines an upright reactor portion with a cross-section that increases upwardly, along with inlet and outlet conduits connected to an inlet and an outlet between which the reactor portion is located. The conical portion contains a bed of substantially water-insoluble alkaline salt particulate, such as MgSO, the bed being such that, when the pH of the inflowing aqueous stream is below 7, contact between the particulate and the aqueous stream will raise the pH of the outflowing stream to a level above that of the inflowing stream.

Device for increasing pH of an aqueous stream

A liquid-handling installation utilizes an upstream and a downstream separator unit, each unit having a horizontal partition defining a treatment compartment below the partition and an overflow compartment above the partition. Each unit has an inlet opening and an outlet opening. Two conduits communicate the outlet opening of the upstream unit with the inlet opening of the downstream unit. The operating process includes: a) dividing first and second substantially equal streams any liquid arriving ay the inlet opening of the upstream unit; passing the first stream through the upstream unit treatment compartment, thence along the first conduit, thence over the downstream unit partition to the outlet opening of the downstream unit, and simultaneously passing the second stream over the upstream unit partition, thence along the second conduit, thence through the downstream unit treatment compartment, and finally to the outlet opening of the downstream unit; and b) when the total arriving liquid is greater than can be accommodated by the two treatment compartments, allowing the liquid to overflow all weirs and partitions and pass directly from the upstream inlet opening to the downstream outlet opening
