The effluents of the paper industry predominantly contain organic contaminants<br />
and solid materials, whereas those of pulp production also comprise nitrogen and<br />
phosphor compounds. The organic load is determined by the theoretical amount<br />
of oxygen required <strong>for</strong> the oxidation of the contained organic compounds (COD –<br />
chemical oxygen demand).<br />
In all NEUSIEDLER plants, all contaminated effluents are mechanically and biologically<br />
treated in order to ensure that all BAT values are maintained or undercut<br />
where possible.<br />
