Eichhornia crassipes

History of the Phosphorus Issue in the Great Lake Back to the history, the eutrophication problem was first time concerned by public on Great lakes at the 1960s, the Lake Erie was covered by algae as a result of over dumped phosphorus from the sewage and other waste water, at that time, the Lake Erie was known as the “Dead Sea of North America”(Fitzpatrick, J. J., and Di Toro 1999). The reason cause this problem can be concluded in 2 points, 1. the stresses of overfishing, 2. development of phosphorus-based

Eichhornia crassipes (Water hyacinth), is considered as one of the world’s most invasive aquatic weeds because of its abundant availability, remarkable adaptive ability, and massive growth rate (Hu et al., 2015). It is very difficult to eradicate water hyacinth by physical, chemical, and biological means, though a substantial amount is being spent on their control annually throughout the world. Water hyacinth is regarded as an attractive raw material for biofuel production like bioethanol and

According from (Edwards et al, 1985) 8 feeding method were figured utilizing possibly composted alternately dried water hyacinth, Eichornia crassipes joined under a routine pelleted tilapia bolster in an straightforward relocation procedure: 100. 75, 50 Furthermore 25% composted water hyacinth: 100, 75 what’s more 25% dried water hyacinth; and a control diet for 0% uprooting of the routine encourage. The test eating methodologies were nourished done copy medicines to Oreochromis niloticus to an arrangement

Eichhornia crassipes commonly referred to as Water Hyacinth is a free floating weed that is commonly found sharing a habitat with S. molesta (Shanab, Shalaby, Lightfoot, El-Shemy 2010). When temperature, radiation, and sunshine duration increase the density of E. crassipes increase and this causes large amounts of phenolic allochemicals in the water where the weed is located (Shanab et al. 2010). Placing the phenolic allochemicals in the water could have a purpose of helping water hyacinth to invade

the fur industry. These creatures now live in 15 other states including Louisiana. They were released into “Louisiana wild by state and federal agencies to provide a new fur resource and to control problem plants such as the water hyacinth (Eichhornia crassipes) and alligator weed (Alternanthera philoxeroides)” ( 1). It did not take long for them

Statement of Purpose My interest in Water, Sanitation and Hygiene (WASH) begun when I was working with the Red Cross in a post disaster rehabilitation project in coastal areas of my home country, Bangladesh. The 2007 cyclone contaminated about 70% of the water sources in the affected communities resulting an outbreak of waterborne diseases. I observed the challenges of providing safe drinking water to the victims which motivated me to pursue my career in this field. By training I am a Civil and Environmental

BEHAVIOUR OF WETLAND SPECIES, BACOPA MONNIERI IN HEAVY METAL, LEAD (Pb) CONTAMINATED EFFLUENT 1Dineshkumar M, 2Sivalingam A 1Research Scholar, 2Associate Professor, Department of Chemical Engineering, Coimbatore Institute of Technology, Coimbatore – 641 014. kdineshd@gmail.com Abstract Treatments of heavy metal contaminants from effluent discharged by industries are more complex than designing the treatment process. Bacopa Monnieri is one of the wetland plant used for the removal of heavy metal

Introduction Introducing alien, exotic, non-indigenous, or non-native species,that lives outside its native environment or habitat, usually arrives there by human activity, either deliberate or accidental. Non-native species can have various effects on the local ecosystem. Introduced species that have a negative effect on a local ecosystem are also known as invasive species. Not all non-native species are considered invasive. Some have no negative effect and can, in fact, be beneficial as an alternative

My interest in Water, Sanitation and Hygiene (WASH) begun during my engagement with the Red Cross in a post disaster rehabilitation project in coastal areas of my home country, Bangladesh. I observed the importance of safe drinking water when the 2007 cyclone “SIDR” contaminated about seventy percent of water sources resulting an outbreak of waterborne diseases in affected communities. I saw the challenges of providing basic services to the victims which motivated me to pursue my career in this field

Aquatic plants Aquatic plants possess an excellent ability to assimilate nutrient and to create favorable conditions for microbial decomposition of organic matter. Compared to the conventional waste water treatment system, Macrophyte based waste water treatment systems have several potential advantages (Hans Brix and Hans- Henrik Schierup, Ambio.Stockholm, 1989): • Operating cost is low • Low energy requirements • Often can be established at the site where the waste water is produced • More
