Siltbuster PMPU20

The Siltbuster PMPU20 provides three stage continuous treatment including pH correction at flow rates of up to 30 m3/hr within a single integrated unit.

Stage 1 Initial pH adjustment to achieve a pH of Circa 10.5, thereby maximising the precipitation of solids.

Stage 2 Recovery of suspended solids within a clarification stage (Effective Settlement area 20 m2). The settled solids collect within a hopper and are removed by the opening of a gate valve, the recovered solids can be decanted into a skip or other similar sludge storage tank, to await off-site disposal.

Stage 3 Final stage pH adjustment to achieve a user set pH. The solids free pH adjusted water discharges by gravity from the units outlet weir.

Typically the unit is configured to operate using either strong mineral acid or carbon dioxide. The use of carbon dioxide has a number of environmental and health safety advantages ,making it the preferred acid of choice for use on a construction site.
