Reclamation of nutrients from kenaf retted wastewater using modified ultrafiltration membrane / Nabilah Huda Abdul Halim

Increase in demand of fiber from kenaf industry, increases the water usage for water retting. Traditional water retting method producing large amount of water in greenish color, high in suspended solids, high BOD load, the reduction of DO, high nutrient levels and non-biodegradable substances where...
