what you need to know about this ecological hygiene

Thinking of installing a phytopurification system for your home? In order to build this ecological sanitation, it is necessary to comply with valid rules and standards. Which one? Our answers.

Thinking of installing a phytopurification system for your home? As environmental protection has become a major concern, ecological methods of sanitation are gaining popularity. Among them, phytopurification stands out as an environmentally friendly solution for wastewater treatment. How to set it up? It’s composed by? Discover the essential things you should know about phytopurification.

What is phytopurification?

Phytopurification is a natural process which uses plants and microorganisms to purify water. Mainly domestic sewage or contaminated rainwater. It is also called sanitation with plants or planted filters.

This system uses the ability of plants and some soil microorganisms to eliminate, decompose or accumulate undesirable substances present in water.

Unlike conventional methods such as septic tanks, phytopurification does not require the use of chemicals, offering a sustainable, eco-friendly alternative.

For the installation of a phytopurification system at home, it is necessary to follow the applicable rules and standards.

Is phytopurification legal?

Phytopurification is an autonomous sanitation system in accordance with the decree of September 7, 2009, which establishes technical requirements for non-collective sanitation facilities with a gross load of organic pollution less than or equal to 1.2 kg/day BOD5.

Where to install the phytopurification system?

Phytopurification can be carried out in the garden and individual housebut also on the scale of a city district or municipality of up to 2,000 inhabitants in order to replace a small-scale collective sewage system.

How does phytopurification work?

These two phytopurification tanks are used for two houses in Ain.

The phytopurification process generally takes place in tanks specially designed called phytopurification basins.

The process can be divided into 2 steps:

● One pretreatment tank, vertical flowconsisting of either a planting of reeds or an all-water pit.

● One cleaning tank, horizontal flowcomposed of plant species capable of absorbing pollutants.

The discharge will then be carried out into a pond or ditch near the facility.

The system relies on the ability of plants to absorb and filter impurities present in the water. These ponds contain a variety of aquatic plants, including reeds, irises, reeds, and other species suitable for water purification.

Phytopurification ponds are designed to create a balanced ecosystem where aquatic plants and beneficial microorganisms work together to break down organic matter and remove pollutants.

The phytopurification process can process various types of pollutants, such as organic matter, nutrients (nitrogen, phosphorus), heavy metals and other toxic substances.

Plant roots serve as support for microorganisms that break down contaminants in water.

This natural approach guarantees efficient wastewater treatment while preserving biodiversity.

How to perform phytopurification (or natural sanitation)?

Setting up a phytopurification system requires careful planning.

The selection of plants adapted to the local climate, the design of a phytopurification tank and the introduction of balanced management are essential steps.

Before your project, it will be necessary to submit a declaration file for the installation of an autonomous sanitation device from the Public Non-Collective Sanitation Service (SPANC).

This must be done in accordance with applicable regulations. A soil study must be prepared by the design office to demonstrate that the principles of your chosen treatment system will be adapted to the management of your service water according to the permeability of the soil.

The file will then be reviewed by SPANC for agreement before the work is carried out. The service also carries out a site visit during the works and before the completion of your autonomous sanitation system to issue you with a certificate of conformity for your individual sanitation project. (Article 3 of the decree of April 27, 2012 concerning methods of fulfilling the mission of checking non-collective sanitary facilities).

What area is needed for effective phytopurification?

The surface area required for effective phytopurification depends on several factors, including the type of phytopurification you are considering (each method may have specific surface area requirements), the flow of water to be treated, the quality of the incoming water, and regional or local wastewater treatment requirements.

Factors to consider when determining the area needed include:

  • THE water flow : the higher the flow rate of the treated water, the larger the required surface area.
  • THE number of housing intended for living in a house: the higher the number of inhabitants, the larger the required area.
  • PUSH type of soil : soil permeability can affect phytopurification performance. Generally, well-drained soil is best.
  • THE a type of plant : The plants used in the phytopurification process may vary in terms of space requirements. Some systems require emergent plants while others use floating plants.
  • PUSH inlet water quality : The initial quality of the water to be treated can influence the design of the phytopurification system.
  • THE local standards : Local standards and regulations may impose specific wastewater treatment requirements that may also affect system design.

It is generally recommended to plan an area of ​​at least 5 to 10 m² per inhabitant to ensure optimal cleaning. However, each project is unique and a specific assessment is required to determine the appropriate size.

A sanitary engineer or water treatment specialist should be consulted to design a phytopurification system tailored to the specific needs of your site and local requirements. These experts can perform calculations based on your specific parameters to determine the optimal area needed.

Phytopurification or septic tank, which wastewater filtration system to choose?

The choice between phytopurification and septic depends on several factors such as location, soil conditions, site size and your personal preference.

PUSH septic is a wastewater treatment system that separates solids and liquids. Solids are partially decomposed. The liquids are then discharged into the septic field. Its operation is simple and commonly used. It is suitable for many types of soil and can be installed in areas with low soil permeability. It requires regular sludge emptying and the treated wastewater may require further treatment before being released into the environment.

PUSH phytopurification, as we saw earlier, uses plants and microorganisms to clean wastewater. Ponds of aquatic plants act as natural filters that remove contaminants. It is an ecological system that reduces the need for frequent draining, is suitable for spaces where space is available and can be aesthetically pleasing. However, it may require more space than a septic tank and its performance may be affected by climate, season and maintenance.

To choose, you need to take into account:

  • THE soil typesome soils are better suited for a septic tank, while others may be better suited for phytopurification.
  • L’vacancyphytopurification may require more space than a septic tank, so make sure your facility can accommodate the system you choose.
  • L’Conversation, consider the level of maintenance you are willing to undertake. A septic tank requires regular emptying, while phytopurification requires regular plant-related maintenance.

It is recommended that you consult with a sanitation professional or environmental engineer to assess your specific site conditions and help you select the system that best suits your needs.

The chosen autonomous sanitation system must allow the fulfillment of the discharge standards established by the state services responsible for the water police, taking into account the sensitivity of the natural environment into which this purified water will be discharged, the limitations of the location of the facility and the size of the city concerned (decree of 27.4.2012 concerning methods of fulfilling the mission of checking non-collective sanitary facilities).

Phytopurification, not to be forgotten

Phytopurification represents a promising ecological sanitation solution that is currently being developed.

By supporting the natural regeneration of water, it contributes to the preservation of natural resources and at the same time limits the impact on the environment.

Before opting for phytopurification, it is essential to consult experts and comply with local regulations to guarantee an effective and sustainable implementation of this ecological solution.
