EnviroHub tanks by Prime Pump

are designed to effectively recover

suspended solid particles from

water in continuous pumping

applications.

It is a simple but effective way

of ensuring that environmental

pollution concerns of high

suspended solids in water, from

activity such as groundwork

dewatering and silt laden wash

water are safely met. This ensures

compliance with authorities and

water standards requirements.

These tanks are typically used with

3”, 4”, or 6” pumps depending on

the flow rate required, however,

where there are greater volumes

multiple units can be easily

connected in parallel to increase

settlement capacity.

Silt laden contaminated water is fed

into the unit in the back chamber,

where it flows around into the

base of the lamella plate section of

the tank. The water stream flows

upward between the Lamella plates.

With the slower flow, the solids fall to

the plate surface, where they slide by

gravity down the plate, to the sludge

collection chamber at the bottom.

The sludge is then periodically

drained down using the valve at the

bottom of the hopper.

About How it works:

Features

• Discharge ports for sludge and water • Motorised solids rake • Removable Lamella plates for easy cleaning • Tapered sludge tank for fast effective sludge removal • Oil water separation & final polishing point if required • Provision for additional monitoring control to report on

final water quality • Flocculation area • Ladder access for maintenance on some models

Benefits

• Safe solution for removing solids from water and minimising environmental damage to water courses

• Ensure compliance with Authority requirements • Provides water suitable for safe discharge to

stormwater.• A settling pond with only 10% of the footprint.• Easy and fast to deploy minimal set up required • Suitable for all suspended solids settlement • Unlimited process time without complete washout • Flocculant cages built in for basic water treatment • Easy transportation: lifting points or fork pockets
