The main purpose of this study is to determine the removal efficiency of nitrogen compounds in the effluentfrom ANAMMOX process used to treat reject water after centrifugation. A pilot model was bulit consisting of fourdifferent Treatment Wetlands beds with different filter substrate and with or without macrophytes growth. Verticalsubsurface flow type filters have been choosen thanks to their highest efficiency in NH4-N removal...

Eco-innovative technologies in wastewater treatment should provide not only stringent standards for the quality of treated wastewater but also ensure maximum recovery of energy and raw materials from wastewater. One of the ways to improve the removal efficiency of nitrogen and phosphorus compounds in existing conventional wastewater treatment plants is pretreatment of reject water generated during the mechanical...

w artykule przedstawiono ogólna charakterystykę oczyszczalni hydrofitowych , rodzaje i konfiguracje systemów oraz zachodzące w nich procesy. Porównano zasady projektowania tych systemów (z ograniczeniem tylko do systemów podpowierzchniowych) w krajach, które oprocowały normy i wytyczne oraz porownano je do zasad projektowania w Polsce
