Looking for effective systems for TSS removal? Learn how to reduce total suspended solids in wastewater and discover which system fits best.
Why removal of suspended solids is needed
Many wastewater streams contain suspended solids. Sewage treatment removes suspended solids, as these can cause problems in wastewater treatment systems, disposal is not allowed, or because they can block up pipeworks and sewers. Furthermore, effective TSS removal is an important step to purify water sufficiently for reuse, thereby lowering the requirement for fresh water.
How to reduce total suspended solids in wastewater?
TSS refers to the solids suspended in water that are not soluble in water. TSS removal is the process of physically removing these particles. Common methods for solids removal from wastewater include sedimentation (allowing particles to settle using gravity), flotation (using air bubbles to lift particles to the surface), filtration (using filters to physically remove particles), and centrifugation (using centrifugal force to separate particles from water).
The best systems for TSS removal
Paques offers two technologies for TSS removal in wastewater, process water, cooling water, surface water and groundwater:
ASTRASAND® for solids removal from wastewater
ASTRASAND® is particularly suitable for continuous and efficient removal of fine particles. This method for TSS removal is ideal in scenarios where biological as well as physical filtration adds value. Such as in tertiary treatment stages that require high-quality effluent.
ASTRASAND® operates continuously, ensuring consistent treatment with a manageable and predictable load on the system. It's effective in environments where both organic and inorganic solids need to be removed. The sand filter provides a habitat for microbial growth, which can further assist in biologically degrading any remaining organic matter.
ASTRASEPARATOR® for TSS Removal
ASTRASEPARATOR® is well-suited for applications requiring rapid removal of sand, grit, and larger particles from stormwater, surface water, and wastewater. It is beneficial in preliminary treatment steps or in situations where water with heavy particulate loads needs pre-treatment before further processing.
