Membrane Bioreactor

Membrane bioreactor treatment.
Biology and filtration together.

A membrane bioreactor (MBR) combines biological wastewater treatment with filtration. Tiny living organisms break down suitable waste. A fine filter called a membrane then holds back the organisms and small solids while water passes through.

Two jobs, working together

First break it down. Then filter it out.

Think of the membrane as a much finer version of a strainer. After the organisms have broken down the waste they can feed on, the membrane separates them from the water. This replaces the settling tank used for that job in many other systems.

The bigger picture

MBR can be part of your treatment plant.

Both sewage plants and some factory wastewater plants can use MBR. It can do a job inside the plant, so you do not always need to add it after a complete ETP.

Before the membrane

Remove larger bits of waste first. Check for chemicals that could harm the organisms or damage the filter.

After the membrane

The water may need another step to kill germs or remove dissolved salt before it can be used again.

Where space matters

A smaller layout may help when space is limited. It still needs room for the amount of water being treated and for maintenance.

Before choosing a system

Good operation is part of the design.

01 / What to check

Suitable incoming water

Test what is in the water and check how much arrives each day. The organisms must be able to live and work in it.

02 / What to check

Care for the membranes

The filters need cleaning, regular checks and replacement when worn out.

03 / What to check

Look after the living organisms

Supply air, check the tank and remove excess sludge, the wet mixture of organisms and solids that builds up.

Let’s talk about cost

What will you be paying for?

With MBR, you are paying for two jobs: a tank where microorganisms treat the water, and membranes that separate water from the solids. Membranes are fine barriers that also need care.

Getting started

Buying and setting it up

The starting price covers the treatment tanks, membranes, pumps, air-supply equipment and controls, along with the installation work included in the quote.

Keeping it working

The bills after installation

Electricity runs the pumps and air supply. You also pay for routine checks, cleaning, sludge removal and water tests. Membranes eventually need replacement, so allow for that future expense too.

Your site, your water

Why prices can differ

The amount and condition of the incoming water affect the size of the system. The cleaning needs, spare equipment and required water quality also affect the total cost.
