Tertiary Treatment for Domestic Sewage Systems

See our more recent blog post on tertiary treatment modules for a more in depth guide and comparison of popular tertiary treatment units on the market today.

Many architects and engineers are now specifying a sewage treatment plant followed by a tertiary treatment module in place of a large percolation area.

Popular tertiary treatment systems on the market today include the following;

Sand Filters

Sand filters are very effective for tertiary treatment. They are layers of certified silica sands and gravels installed to EPA designs. Limitations of sand filters are that they can be large, expensive to install and require a certain degree of skill by the installer.

Coconut filters

There are some new tertiary treatment products on the market now that use waste organic material like peanut shells and coconut shell fragments to treat wastewater. These systems come in a tank preinstalled. The advantage versus a sand filter is that they are tank based systems so they are simple to install. A disadvantage is that they are expensive in terms of cost price and maintenance.

Filterpod Units

Biocell offers filterpods for tertiary treatment. Certified to EN12566-3 and EN12566-7.  The systems are ready to go and come preinstalled in a small tank. Additionally, the filterpod can be used in place of a percolation area. The filter media is synthetic – and costs far less to replace than organic waste material. Far better value and easier to install than sand filters.

  1. Hi,
    I have a plastic bicycle fan assisted unit fitted and council days I need an additional sand filter fitted. The area around unit is slightly under the reg size distances and a sand filter is needed for planning retention. Can you give me details of what this is and ball park costs please
