CHAPTER 1 The Problem and Its background 1.1 INTRODUCTION The growing interest in the past to produce green materials that can reduce the problem involving waste materials by non-fibrous materials led to the development of natural fiber reinforced thermoplastic composites. Water Hyacinth (Eichhornia crassipes) also known as “water lily” is an aquatic plant which is found floating freely in the surface of fresh waters. Its rate of proliferation under certain circumstances is extremely

TOPIC 1- INTRO TO CELL BIOLOGY Cell Theory: 1) all organisms consist of one or more cells 2) the cell is the basic unit of structure for all organisms (Theodor Schwann) 3) all cells arise only from pre-existing cells (i.e cell= basic unit of reproduction) (Rudolf Virchow) Cells have enormous diversity (function and size)‚ but have unity (similar basic chemistry i.e DNA‚ ATP‚ metabolism‚ etc.) ** units: 1µm= 10-6m‚ 1nm= 10-9 m (typical prokaryote is 1-5µm‚ typical eukaryote is 10-30 µm)

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in
