Settling Tanks & Bags
Remove silt, solids and oils from site water before discharge.
Match the tank to the site
Prime’s settling tanks slow site water down so sand, silt and other solids have time to settle before discharge. Choose from standard baffle tanks, hybrid settling tanks and reusable settling bags to suit your flow, solids load and wider treatment setup.
Add oil and hydrocarbon separation where you need to remove floating contaminants.
Standard settling tanks
Standard baffle tanks slow the flow to settle sand, silt and heavier solids during wellpointing, dewatering and general site discharge. They’re a practical choice where you need reliable sediment removal without the added settling media used in a hybrid tank.
- Sizes from 4–20m3
- Removable lid for cleaning
- Oil separator
- Chemical dosing options
Hybrid settling tanks
Hybrid settling tanks combine baffles with lamella-style settling media to improve sediment removal in a compact setup. They suit sites that need more treatment performance than a standard baffle tank – but keep the system modular and easy to deploy.
- Capacity of 9m3
- Stackable design
- Removable lid
- Outlet ports for cleaning
- Chemical dosing compatible
Reusable settling bags
Reusable settling bags use gravity and filtration to separate solids from sediment-heavy water. These sludge bags can work individually or in sequence as part of a staged dewatering setup.
- Gravity-fed filtration without power
- Reusable bags with frames supplied
- Connect multiple bags for staged separation
The right option depends on your flow rate, solids load and site setup. Prime can help you choose between a standard settling tank, hybrid settling tank or reusable settling bag.
Groundwater management in New Brighton
Prime used a settling tank as part of a groundwater management setup for a coastal dewatering project in New Brighton.
