AC flow-controlled phosphorus trap

A real flow-controlled phosphorus trap that doses the right amount of chemistry depending on water use in the house.

Placed between the sludge separator and the infiltration.
The technical well is placed near the pump well, in it there are electrical cabinets, chemical pump and chemical canister to ensure a good environment.
The wastewater flows by gravity to the pump well.
All water is pumped out from the pump well and in this way you get the right volume of chemistry to be dosed to the sludge separator.
About 10% of the pumped out water is led back to the sludge separator to create movement of the water in the sludge separator so that the chemistry can be mixed in effectively.

In addition, you get a pump solution from the sludge separator to the bed, which extends the life of the bed and increases the degree of purification.

To successfully reduce phosphorus with chemistry, the following is required.
The flocculant reacts with water and just seconds later it is ineffective. Since the time is very short, phosphorus in the toilet water must be met with the flocculant within 10 seconds for optimal reduction.

For the meeting between the phosphorus and the flocculant to be effective within the active time, movement is required, which takes place with a return pumping of outgoing sludge separated water together with the chemistry.

No risk of mis-dosing thanks to flow-controlled pumping.
Overdosing can result in sludge escape in the separator which clogs the infiltration. Underdosing results in no reduction of phosphorus.

Through customized dosing of flocculants, you get your plant to meet high phosphorus levels. There is no need to manually adjust the dosage after changes in the household or when leaving the house for vacation as needed on other simple chemical pumping systems.

Alarm
Alarm indicates when it is time to add new chemistry.

Easy to use
No adjustment of dosage due to changing number of people in the household or unplugging when leaving home. Everything is done automatically all the time.

Advantages
– Real flow controlled dosing
– Can handle highly variable loads
– Easy to install
– Never overdoses
– Easy and safe to use
– Pump well included for better longevity and function, great if you have problems with heights.

Suitable chemistry and flocculant is PAX XL 60

You should not compromise on the size of the sludge separator, the hydraulic properties when using chemistry become much more difficult for the sludge separator so you must get a slower flow otherwise the risk of sludge escape is great.
It does not help to have several emptyings, but the size should be double the normal.
