SEWAGE TREATMENT

What is a secondary sewage treatment? (Puraflo after septic tank)

OVERVIEW

For the past few years, local and environmental regulations have significantly changed. What is the latest sewage treatment legislation update? 2020. Throughout the kingdom, more and more housings need an extra treatment solution to support their primary system and ensure a higher effluent quality. For some of them, it is mandatory and required by the government. What is a secondary sewage treatment, and how does it work? Have a look at Tricel’s solution.

With its packaged filter system (Tricel Puraflo), Tricel is reinforcing its position on the market.

Known as a leader in the wastewater treatment industry, this traditional and family-oriented company learned to put its customers’ needs first, no matter what they were. When the local regulations changed, we were responsible for following this path and embracing this environmental awareness. For this reason, we provide a product that could help you comply with governmental guidelines whilst upgrading your existing septic tank.

It will be installed at the end of your primary system (septic tank) and work to improve your wastewater quality. But typically, you might wonder what a secondary sewage treatment is and why you are requested to invest in one.

KEY BENEFITS FOR YOU:

► Minimal power requirements, (approximately £10 per annum). The only mechanical device in the system is the pump, which works intermittently, minimising the possibility of mechanical problems. 

►The modular design of Puraflo can be installed above or at ground level. It doesn’t require concrete backfill and can utilise the existing excavated material as a backfill. 

► Quick and easy to install 

► No de-sludging required 

► Fits for main or holiday residence applications

Tricel’s interpretation of the secondary sewage treatment system: Tricel Puraflo (packaged filter system)

When talking about secondary or tertiary treatment systems, we expect an extra purification process to improve the quality of your effluents. It is usually required for sensitive sites, such as watershed-protected areas, which need a higher level of filtration for the treated water to be dispersed. With our Tricel Puraflo, you can eliminate remaining inorganic compounds and substances (ex: nitrogen and phosphorus).

How does the Puraflo work?

Tricel Puraflo modules located after a septic tank provide a secondary treatment plant. Tricel Puraflo modules located after a wastewater treatment plant provide tertiary treatment. The illustration above represents a tertiary treatment. However, the process once the effluent enters the Puraflo modules is the same.

  • The sewage will be dispersed evenly into the modules thanks to a pipework system. 
  • Effluents will be treated with a combination of biological, chemical and physical processes that have proven to be one of the most efficient on the market.
  • The effluents will exit through an outlet pipe and go into an approved disposal method (percolation area).

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)

UK sewage treatment plants must comply with EN 12566-3 2005 regulations. 

You should also hire a professional to install your sewage treatment system. For any sewage treatment plants you intend to install, you should also check your local guidelines to determine if planning permission is required.

A sewage treatment plant is where domestic wastewater and sewage are treated. The sewage treatment plants break down organic matter through the primary settlement and aeration chambers. Sewage treatment plants require little maintenance and have low running costs, and sewage effluent is discharged into drainage fields or watercourses.

For example, the required standards are 20:30:20 for BOD, SS, and NH4.

Tricel® has achieved an 11:16:9 result during independent testing.

In order for the biomass to reach its optimum purification, it may take up to 16 weeks.

You may be able to discharge directly into a watercourse or to a percolation area depending on your region. Find out which option is best for you by contacting your local council.

The sewage treatment plant’s size depends on the effluent volume from your house. It is determined by the number of people using the system, which is calculated based on the number of bedrooms in your home. If you need further information, contact our team.

Occasionally, your sewage treatment plant will need to be emptied due to the accumulated sludge inside – usually once a year. The frequency of emptying your treatment plant depends on its size and usage. See our dedicated page about desludging septic tanks and wastewater treatment plants.

1) to prevent surface water from entering the tank and overloading the system as this can inhibit growth of the bacteria and could reduce the effluent quality.

2) to prevent water getting into blower housing which can harm the control panel and the air blower.
