CHAPTER 1 INTRODUCTION 1.1 Background of the Study Generally‚ Palm oil mill effluent (POME) contains high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) which can pollute the environment ecosystem if it is not treated properly. The characteristics of fresh POME are that it is highly viscous liquid‚ brownish in colour and discharged at a temperature of 80-90oC. Moreover‚ POME is extremely poisonous with a very low pH between 3.5 and 4.2‚ high chemical and biological oxygen demand

with the oxygen in the environment then the iron does‚ thus creating a small film around the iron‚ blocking from contact with oxygen. The 4 metals that are being used in our experiment are common Steel‚ Zinc coated Iron (galvanized)‚ Copper‚ and Aluminium. Steel is commonly used in ships and submarines. Steel is an alloy of mostly iron alloyed with between 0.2% and 2.1% carbon‚ but the most common steel found on ships is a low carbon alloy. Metals like Magnesium and Chromium can also be added to this

Lack of quality control that causes build quality issues While other smartphone makers are trying to produce a better build quality like Aluminium Samsung stays put and uses’ plastic as it flagship devices according to (Blum‚ 2012)” and while plastic can be tough in a way or two‚ without proper quality control ” defects are being reported by the consumers according to” (Ray‚ 2012) Opportunity

precipitate forms as more sodium hydroxide was added to the unknown substance the possible cations include: Aluminium‚ Lead (II) or Zinc. Furthermore if a white precipitate forms that does not dissolve as more ammonia solution is added it could mean the cation could be Aluminium‚ Lead (II) or Magnesium. This therefore means that further tests would need to be carried out in order to identify the aluminium. Following the Cation tests we found that sample C was copper as the addition of dilute sodium hydroxide

it occupies a place analogous to a textile fiber. Wire-cloth of all degrees of strength and fineness of mesh is used for sifting and screening machinery‚ for draining paper pulp‚ for window screens‚ and for many other purposes. Vast quantities of aluminium‚ copper‚ nickel and steel wire are employed for telephone and data cables‚ and as conductors in electric power transmission‚ andheating. It is in no less demand for fencing‚ and much is consumed in the construction of suspension bridges‚ and cages
