pH Correction

Siltbuster’s pH correction systems make neutralisation safe and straightforward, whether using single‑stage reaction tanks or integrated multi‑stage setups to achieve pH 7 for discharge or a user‑defined level within a wider treatment process.

Traditional methods rely on strong mineral acids, which are difficult to control, require specialist PPE and training, and can create secondary pollutants when their anions enter the water. To avoid these issues, Siltbuster systems use digital pH controllers and probes to automatically dose vapour CO₂, offering safer handling, easier process control, lower operating costs, and no secondary pollutants. CO₂ cylinders are robust, easy to return when partly used, and cannot overdose or acidify waters, making this approach a reliable, operator‑friendly alternative to conventional acid dosing.

PMPU20

The Siltbuster PMPU20 is an integrated solution that comprises two dedicated reaction tanks and integral lamella clarifier for the multistage manipulation of pH levels and removal of suspended solids.

This sequential treatment philosophy not only reduces the amount of reagent required per cubic metre of water, but also reduces the hardness/alkalinity and improves the treated water quality upon discharge.

The PMPU20 has a typical continuous operating range of up to 20m3/hr and also incorporates its own onboard peristaltic slurry pump controlled via an asymmetric timer for the disposal of the captured slurry or for its recirculation where users have a High-Density Sludge (HDS), so as to minimise underflow removal costs. The system can be configured to work with vapour carbon dioxide should an alkaline value be detected, or used in conjunction with caustic solutions should the feed to be treated have an as-received acidic value.

_{Typical applications: Precipitated Solids Removal, High pH Water, Low pH Water, Hydrodemolition}

DS4

The Siltbuster DS4 pH correction unit is a single-stage pH adjustment system that can be configured to correct the pH of either alkaline or acidic waters, capable of treating flow rates of up to 20 m³/hr.

When treating waters that also contain suspended solids, the Siltbuster DS4 pH adjustment unit can be operated in conjunction with a Siltbuster Lamella Settlement unit, as part of our wide range of plug-and-play modular fleet options.
