SDS Aqua-Filter™ is a unique and highly efficient water quality treatment solution.

By using the SDS Aqua-Swirl® swirl chamber for pre-treatment, followed by a filtration chamber for secondary treatment, SDS Aqua-Filter™ maximises the removal of suspended solids by up to 80%. This means that nutrients, heavy metals and hydrocarbons are removed from surface water runoff prior to its final conveyance to a suitable outlet. It also helps to eliminate 40% of total phosphorous.

How does it work?

SDS Aqua-Filter™ is designed with an internal flow diversion to bypass the flow when the filter media is saturated and awaiting maintenance. So, if there’s a major storm, any excess water is diverted from the filter to prevent any risk of back-up. The initial flush will always be treated, and the captured pollutants held until they are removed and disposed of, in line with local guidance.

How is it installed?

Systems are sized according to site specific water flow rates, treatment and quality requirements and can even be manufactured to a bespoke size.

SDS Aqua-Filter™ should be installed in an off-line configuration using an upstream diversion structure to direct only the designed water quality treatment flow through the Aqua-Filter™ system.

Twin or multiple Aqua-Filter™ system configurations can be implemented to allow for higher treatment flow capabilities beyond that of a single unit.

Due to its small size and low weight, installation can be easily carried out without a crane or other heavy machinery.

SDS Aqua-Filter™

Maintenance is just as simple too. SDS Aqua-Filter™ has no moving parts and provides direct access via inspection chambers from the surface to the sediment and oils accumulated in the filters.
