Estrogens are a growing problem in wastewater discharges because they continuously entering the environment and biologically active at extremely low concentrations. Their effects on wildlife were first identified several decades before, but environmental limits remedial measures still not completely elucidated. Most conventional treatment processes designed with sufficiently long retention times to effectively remove estrogens. Nature-based technologies such as wetlands (TW) high-rate algal ponds (HRAP) economically feasible alternatives for decentralized have promise removing steroid hormones including For small communities populations below 50,000, overall cost of TWs HRAPs is considerably lower than that advanced activated sludge systems (AS) sequencing batch reactors (SBR). This results from simplicity design, use less materials construction, energy use, operation maintenance costs, by non-skilled personnel. The nature-based show high removal (>80%) both natural synthetic Estrogen can be enhanced using alternative media palm mulch, biochar, construction wastes bricks, instead traditional substrates sand gravel. While effective estrogen removal, disadvantage requiring relatively large footprint, this reduced intensified multilayer wetland filters (IMWF). Using filamentous algae HRAP (high-rate pond; HRFAP) an emerging technology treatment. supply oxygen via photosynthesis assimilate nutrients into readily harvestable biomass. Diurnal fluctuations pH these provide conditions conducive breakdown estrogens wide range other contaminants. performance varies seasonal changes (particularly temperature solar irradiation), however greater understanding operating loading rate, hydraulic time (HRT), pond/bed depth, dissolved (DO) concentration pH, which influence mechanisms (biodegradation, sorption photodegradation) enable successfully used
