Stevenson Aggregates – Tefsa Filter Press

About the Customer

Stevenson offers aggregate solutions for commercial, infrastructure and residential use. This includes roading, drainage, sand, concrete, and other specialised products for use in landscaping, construction and infrastructure.


Stevenson was looking for a solution to optimise their quarry wash water treatment and recovery process.


MIMICO provided the New Zealand-first installation of a Tefsa PEH-1500 filter press.

The combination of a Lamella incline plate settler and Tefsa filter press offered a new dimension to Stevenson’s operation. This solution allows them to treat process wash water and recover up to 95% of the water, leaving behind an easily handleable cake.

Tefsa is a Spanish company, specialising in the design and manufacture of filtration equipment.

Why was MIMICO chosen for the job?

MIMICO is a long-term partner of Stevenson, and has a strong history with the Lamella incline plate settler, used for clarifying process wash water. The installation of a Tefsa filter press took this to the next level.
