To safeguard the most precious of our natural resources, you need a reliable solution for wastewater treatment, capable of safeguarding people's health, protecting the environment and complying with increasingly stringent regulations at the same time.

The Aliaxis portfolio offers extremely robust solutions perfect for managing commercial and residential wastewater in a safe and sustainable way.

In addition to pre-treatment systems for heavily contaminated water (used for example in restaurant kitchens or car parks), we offer a comprehensive range of reliable treatment solutions for homes that are not connected to municipal sewage networks. The range also includes options for the recovery of non-potable gray water, useful for toilet cisterns and garden irrigation.

REDI systems for pre-treatment include degreasers for restaurants, oil and hydrocarbon separators for parking lots, and sand traps for coastal applications.

For large-scale projects, Aliaxis also offers customized solutions for the treatment and reuse of wastewater for non-potable uses.

The ISEA wastewater pre-treatment systems before delivery to the public sewer are made up of:

Degreasers for the pre-treatment of gray water of civil origin (kitchens, washing machines, sinks, showers, etc.)

Biological IMHOFF for the pre-treatment of sewage of civil origin (from toilets)

Septic tanks commonly used where there is no separation of gray water discharge from black water discharge.


The ISEA purification systems before delivery to the public sewer are made up of:

Trickle filter systems anaerobic or aerobic: The purification process is biological and is based on the purifying action exerted by the bacterial flora

Activated sludge plants: The purification process is biological and is based on the action of aerobic bacteria, which feed on the organic substance contained in the incoming sewage.

Sub-irrigation and phytoremediation systems with absorbent trays: The purification process exploits the evapotranspiration capacity of the soil, both directly and through plants, and the absorption of the organic elements of the sewage by the root systems of the plants themselves.


Lifting systems

Lifting stations are used to convey wastewater to final delivery points located at higher elevations and at a certain distance from the discharge points.

They can also be used to regulate the flow rates entering the purification plants, guaranteeing a constant flow where required.
