          National Agreement number 2010-007

                                                                                      

COMPACT'O® 4 ST2 sewage treatment filtration system is  manufactured by a french company in the waste water treatment industry with years of experience.                                 

The COMPACT’O® 4ST2 has evolved over the years, becoming the system which has been successfully accepted by the authorities, government ministers and certified in the Agrément National France N°2010-007.   

                       

                                                                                       

 Utilising biological techniques, the products operation requires no electrical powered moving parts to perform its purification process.  

            TheCOMPACT'O® 4ST2 is a compact filter system for assainissement non collective(ANC) for properties not on mains sewage drainage.  They are suited for properties that have not enough or suitable land for a conventional sand bed filter/drainage sewage treatment system.  The systems can be used for small and medium properties, for week-ends, holidays and gite occupation.  The units can also be made up into multiple units for larger properties eg.schools, offices, shops and camping sites.    

How the  sewage treatment units work

The treatment system comprises of two stages.  The waste water from sinks, washing machines,  toilets etc, firstly goes through :-

2 Pre settlement tanks (fosse toutes eaux)

Here the separation of the effluent takes place into solids and fluids.  Solids are biologically digested, the resulting sludge having to be reduced or removed as a legal requirement, by a registered vidange company every 3-4yrs.

The effluent fluid then passes through a prefilter which prevents foriegn bodies eg:-baby wipes, sanitary products going into the treatment unit.

In this the second stage, the effluent fluid enters and is dispersed as small droplets.  Using gravity and capillary action the fluid slowly permiates the treatment media. 

The  filtration treatment unit consists of :-

A filter media consisting of fibres derived from natural rock, which are manufactured in to varying sized cubes. This massively increases the surface area, on which the bacteria lives, multipies and digests anaerobically, micro organisms in the fluid as it passes through.  This process purifies the fluid.

A ventilation system. 

For the bacteria to thrive and perform their natural process they need to have a  supply of fresh air.  As the unit is designed for aerobic digestion, ventilation is important.   Utilising naturally occuring convection currents, air enters, passes through and exits the unit by a wind powered extraction system. These processes occur naturally.

The treated effluent discharge is purified to the standard and normes FR EN 12566-3+A1.   The products are manufactured in compliance with the CE regulations and have the CE mark.

COMPACT’O® 4 ST2 is accredited with the Agrément National France N° 2010-007 and can be installed nationwide with SPANC approval, as to the usage and the site.                                       

TheCOMPACT'O® 4 ST2sewage treatment system complies with the XP DTU 64-1 French systems and standards.  

COMPACT'O® 4 ST2 is a system that has the criteria to enable financal assistance with a government initiated scheme "ECO PRET 0%" which is a loan obtained from participating banques, where by you don't pay interest 0%.

Care and maintenance of the COMPACT’O® 4ST2 system

 The filter in the sewage/pre settlement tank requires regular cleaning (at 6 -12 monthly intervals) and before the emptying of the sewage/pre settlement tank.

 When the pre settlement tank is emptied the sides of the tank are jet washed. The intervals between empting and cleaning can be adapted depending on use, it is obligatory that attention is necessary no longer than 4 yearly. It is important that the pre settlement tank is not left to get too full, empty when the tank contains approx. 50% sludge. The empting (vidange) must take place by a registered company and documentation given to that effect.

 The tubes in the filtration unit from which the effluent disperses on to the filter media are cleaned (6 -12 monthly) this period can be adapted depending on the use, the function and performance of the filter unit.

 In the case that the filtration media becomes saturated with broken down effluent deposits after some years, the unit will require cleaning and the media will have to be renewed to return the filtration to its optimal function.  

Important precautions need to be taken to maintain a well functioning COMPACT’O® and all filter units.

        Care must be taken to make sure that oils and grease from the kitchen or vehicles, wax, resines,paints, solvents, petrol, diesel, all pesticides, all bacteriacides,toxic products,  condensed water from air conditioning units, fabric conditoners, water from a swimming pool, rain water from gutters and land drains do not enter the filter unit.

Products in the market for activating sewage tanks/pre settlement tanks must not be used.
