Tricel Maxus - Sewage Treatment Plants


Tricel Maxus sewage treatment plants are strong and easy to install, with numerous possible configurations to suit any site.

This sewage treatment plant is simple in operation and easy to maintain over the product’s lifespan.

The Tricel Maxus, is a commercial plant that uses Submerged Aerated Filter (SAF) technology. All electrical components of the plant are connected through the E-III control panel. 

Examples of usages include:

  • housing estates
  • hotels
  • restaurants
  • campsites
  • factories or retail units, to name a few.

These highly versatile systems are individually sized to suit every scenario over 50 Population Equivalent.

The Tricel Maxus Commercial Plant operates on a highly effective SAF technology treating wastewater in 4 stages:

Stage 1: The settlement tank

The primary treatment occurs here. As the wastewater enters the Tricel Maxus system, the heavy solids are separated out and settle (forming a sludge on the tank’s base). Subsequently, the lighter solids, such as oils, fats or grease, float to the top of the wastewater and are retained within the settlement tank.

Stage 2: The buffer tank

The incoming water load fluctuations are evened out here. The wastewater is fed forward into the treatment plant thanks to pumps located at the bottom of the buffer tank.

Stage 3: The biological treatment zone

The wastewater passes through, the submerged aerated filter (with a large surface area for the microbes) and is exposed to aeration.

The aeration is matched to the incoming flow to ensure efficient operation, thanks to the adjustments made by the control panel. Because of this, the system will not clog nor need any maintenance or chemicals.

Stage 4: The clarifier

Here, the bio sludge from the treatment process settles out of the treated liquid. Thanks to the airlift pumps, the bio sludge from the tank’s base is recirculated back to the settlement tank. The fully treated liquid is now ready to discharge from the plant.

Key features & benefits

Proven SAF technology providing an excellent treatment.

Low running costs (simple operation using long life reliable components).

Easy to maintain (no moving parts within the commercial plant).

Full bespoke design engineered solutions offered to ensure best performance.

Suitable for seasonal loads or constant loads. The control panel will automatically adjust to the incoming load to ensure optimum performance. This commercial plant can adapt to different loadings or effluent strengths.

Suit any site (can fit into difficult sites or simply save space).

Extensively tested and ETA verified for holiday home applications. System will go into power saving mode during periods of no flow and restart once flow is detected without the need for any manual inputs.

Frequently Asked Questions

A cesspool is a simple storage vessel with an inlet and no outlet. It’s a sealed storage vessel; all the water coming in stays within the tank. The advantage is it doesn’t need an outlet. The disadvantages are: there is no treatment, the tanks are huge, and it needs regular emptying. Everything which has gone in must be sucked out. Ideal for sites which have got very infrequent use (Sheppard huts, for example).

A septic tank has an inlet and an outlet; it’s a simple overflow system. See how a septic tank works here. The advantages of the septic tank are there is no mechanic and no electricity requirement for it to work. The disadvantages are you are discharging dirty water, and untreated sewage effluent, as a tiny breakdown has occurred in the tank. You can only release water to a drainage field for the water to go through the subsoil to treat the water.

A sewage or package treatment plant has an inlet and an outlet; the wastewater is treated inside the tank. Aeration is provided inside the tank for the aerobic bacteria to feed on the waste and remove it from the liquid. The advantages are the wastewater is treated and can be discharged to a watercourse. 

Many package treatment plants are available on the market:

  • Trickles filters
  • Rotating Biological Contactors (RBC)
  • Mobile media bio-reactors
  • Activated Sludge systems
  • Sequence Batch Reactor systems (SBR)
  • Fixed Bed Systems (like the Tricel Novo)

Domestic wastewater is all wastewater generated inside the house, including grey water from sinks, showers, baths and sewage from toilets. Rainwater is not classified as greywater and should be directed to a soakaway.

A trial hole can be dug during the site assessment and left open for 48 hours to determine this. The ground level is used to measure the water level.

After the water is discharged, it must flow into a drainage field or a running watercourse. It will fail and block up very quickly whenever it is released directly into the ground. It will also violate the government’s General Binding Rules for small sewage discharges—more information on this page.
