The big problem with septic tank systems is that their soakaways block with suspended solids which are carried out of the septic tank outlet and into the soakaway itself. These solids eventually ruin the soil porosity and the soakaway fails.

Septic Tank and sewage treatment plant final effluent is filtered before discharge in most countries throughout the world, except for the UK and Ireland.

The Septic Filter is fitted into the vertical part of the 'T' on the outlet pipe from our two chamber septic tank and removes up to 70% of the fine suspended solids from the discharging septic effluent and up to 30% from a sewage treatment unit, vastly increasing the quality of your wastewater and protecting the soakaway from blockage.

It requires NO electricity and minimum maintenance - you simply pull it out of the tank by the handle, hosepipe it clean and push it back - simple as that!

With over one million filters installed in septic tanks and sewage treatment plants throughout the USA and abroad, these filters are the answer for all your wastewater filtering needs.

How the Filter Works

Thousands of unprotected septic systems fail every year. WTE receives calls every day from people whose soakaway has failed, sometimes after only a couple of years. A small investment in an effluent filter helps you protect your septic system from costly repair.

With a Septic Filter installed, solids are kept in the tank so they can be further broken down and kept out of your soakaway drains.

The Effluent Filter directs the outgoing effluent through either a series of very fine slots or bristles which prevent anything over 1/16th of an inch leaving the tank. It also encourages the growth of millions of aerobic bacteria throughout its matrix which further digest the organic matter in the liquid.

Slot or Bristle Filter? Zabel septic tank filter

The 'Slot' filter forces the effluent to flow through a series of narrow slots and the patented flow reduces the trapping of solids in the filter by allowing them to slough off and fall back into the tank for further digestion.

Slots provide less surface area for solids to attach and promote the sloughing action.

The slot filter is used in the BIOROCK sewage tank.

The Filter Range

The range extends from filters suitable for single domestic dwellings to filters suitable for treating up to 20,000 litres/day.
