Water Weed

Water hyacinth is the world's worst water weed that is responsible for many environmental and economical problems. Nigerian fresh waters have been infested with this aquatic weed. In this work, a Natural Convection Mixed Mode Solar Dryer for drying water hyacinth to about 10% of its moisture content was constructed and tested as a component of controlling its infestation of the River Benue. The performance of the dryer was compared with the traditional open–air sun drying as the control for drying water hyacinth in Makurdi, Benue State Nigeria. The water hyacinth was dried for 8 hours each day for 4 days. 500g of water hyacinth on wet basis was dehydrated by about 437g on dry basis in 20 hours in the dryer while the control required 32 hours. The dryer was found to be technically more suitable for drying water hyacinth both in terms of the drying rate and quality of the dried product.

Urea and heavy metals (Ni2+ and Cu2+) higher concentration infl uence on the photosynthetic pigments’ content, lipids peroxidation intensity and urease ferments activity in the submerged aquatic macrophyte – Egeria densa Planch. have been studied. It has been shown that addition of metals to the medium with urea tends to strengthen its toxic effect upon plants. It has been found that four-day long hatching of plants in the medium with urea and nickel lead to the oxidative stress development in Canada water weed leaves. Copper concentration equal to 100 mkmol/l appeared to be lethal for plants.
