SAF – Submerged Aerated Filter Design

Overview

We recommend SAF (Submerged Aerated Filters) for commercial projects, especially if organic matter is to be reduced (BOD and COD reduction) or if ammonium is to be reduced (NH4).

Contact us if you would like to discuss options for total nitrogen reduction.

Tricel Maxus Commercial Wastewater Treatment Unit

Submerged Aerated Filter (SAF) design has the following characteristics:

  • Low maintenance requirements and very stable cleaning process
  • Adaptable to fluctuations in incoming water (particularly in connection with Tricel’s buffer tank)
  • Energy-efficient
  • Minimal footprint

In the Maxus plants, the following components are present:

  • A septic tank for solids retention (1 below)
  • A buffer tank for timed inflow of treatment water (2 below) 
  • A treatment unit in which the bacteria live on submerged aerated filters (aerated zone – 3 below) and settling zone (4 below) to remove suspended solids.
  • From the settling zone to the septic tank, there is recirculation. All solids are sent to the septic tank this way. Aerated water containing oxygen is returned to the septic tank, eliminating the system’s hydrogen sulfide (H2S) and reducing smells.
How does the Tricel Maxus work

Maxus one-step system

Maxus one-chamber systems treat wastewater to a standard of 20-30-20 level. 

  • 20 BOD
  • 30 SS
  • 20 NH4
Maxus one-step system

Maxus two-step system

The two-step system is ideal if you are looking for higher-quality effluent, such as reducing BOD outgoing to below 10 mg/l.

Maxus three-step system

The three-sept system is recommended where there is a lower ammonia requirement.

This process can reduce Ammonia (NH4) to less than 5 mg/l.

Example of Submerged Aerated Filters (SAF) in use:

Above-ground installation at a factory in Co Cork.

Overground treatment unit (below), followed by the underground septic and buffer tank (foreground) with an overground treatment unit (background).

In-ground installation at a hotel, in Scotland

A septic tank (not in the photo) is installed before the treatment unit. In this case, the buffer tank was part of the treatment unit for ease of installation.
