pH Adjustment – Batched

MAK’s pH Adjustment – Batch (PAB) plants are designed to automatically adjust and maintain the pH level of raw water in a batch tank prior to discharge to sewer/environment or reuse/recycling. The standard treatment process includes a batch tank, a recirculation pump to turn over the contents of the batch tank, an inline pH analyser which monitors the pH level and a dosing pump to automatically dose liquid alkali/acid. The recirculation pump is also used to discharge the treated water at the end of each batch cycle. Dual chemical dosing pumps (alkali/acid) are available for when the raw water pH varies to allow for correction of both low and high pH raw water.

The system components are sized to suit the batch tank and to allow for a 1 hour complete batch cycle. Optional equipment upgrades include; a feed pump, duty standby recirculation and dosing pumps, high/low pH levels, dual chemical dosing pumps (alkali/acid). MAK PAB plants are available as skid mounted or containerised systems for easy deployment to remote locations.
