Do you require a package treatment plant that can achieve very low levels of phosphate & nitrate removal?

With our Graf systems we can offer a high level of phosphate & nitrate removal here is a guide as to what they can do.


Nutrient Neutrality Guide – 

Client requirement would generally be one of the following –

 

Removal of phosphates & nitrates from the treated effluent

Removal of just phosphates

Removal of just nitrates

 

You may see the following terms –

TP = total phosphate

TN – total nitrate

 

One2Clean Biological – Standard system with small software adjustment.

 N =         Efficiency – 87.0%            Effluent – 7.9mg/l

 P =          Efficiency – 80.20%          Effluent – 1.6mg/l

 

One2Clean +P – Phosphate Removal Dosing Package

 

P =          Efficiency – 95.1%            Effluent – 0.4mg/l


Here are the options you may consider when applying for building control approval.

Option 1 -

Put forward the biological (aeration only no dosing) O2C 5-18PE treatment plant.

Currently this seems to be the preferred option as NE & NRW seem to be resistant to dosing unless a robust maintenance/service package can be shown.

Option 2 -

An upgrade to dosing which includes an upgrade to an advanced system (control panel) + the dosing +P package.

Option 3 – Only required if purchased before planning approval given so need to keep both options open.

An upgrade from Option 1 - the Advanced biological (aeration only no dosing) O2C 5-18PE treatment plant.

Fitted with maxi dome & includes 6mm dosing hose.

This allows for the dosing +P package to be added after installation if required.

The maxi dome can be fitted out for storing the 25L dosing solution container.

The 6mm dosing hose would be pulled through the ducting with the air hoses so in position for connecting later if required.
