Essays on Suspended Solids

1. Intake with screen removes floating, large solid impurities. The removed solids are called screenings, and they are treated and disposed as solid wastes. Mixing tank is where coagulants such as alum, aluminium sulfate, ferric chloride, ferrous sulfate or lime are mixed with raw water (Al-Najar), there is no waste stream generated from mixing tank since the process is quick and there is no time to settle. In, the flocculator slow mixing occurs to allows for floc formation, the chemicals added in mixing tank promote this process. Flocculated suspended impurities settle sooner due to their large size and mass. ...

Edible oil refinement is one of the major problems faced by the developing countries across the world as edible oil effluents are a major source of environmental pollution. Owing to this, it is essential to ensure that the effluents are treated prior to its disposal. The composition, characteristics and quantity of the waste water generated depends on the operating conditions and processes followed and can vary from different organizations in the same industry. An investigative method comprising of an in-depth study of unit operations, monitoring, measurement and analysis of parameters affecting environment, and performance evaluation of utilities and pollution ...

Abstract

Solid waste and wastewater are primary sources of pollution from food processing industries. The wastewaters usually contain high suspended solids, organic starch and sugars that may contain toxic substances to the environment. Solid wastes come from organic materials while the mechanical preparation processes need biological treatment before releases into the environment. When untreated, they find their way into other water plants like lakes and streams. Since they have higher nutrient content, they result of eutrophication of the water systems hence causing algal growth. It, therefore, compromises the stability of the aquatic ecosystems as the water quality is changed. It ...

Dissolved Oxygen

INTRODUCTION Dissolved oxygen is a useful parameter used to determine the level of effluent in waste water treatment. Living organisms in water bodies require oxygen to break down organic matter. These organisms consume the dissolved oxygen in water and give out carbon dioxide. Oxygen does not readily dissolve in water and gets depleted quickly by increased micro-organism activity. To maintain optimal oxygen levels in a water body, the oxygen replenishing rate from the air should be equal to dissolved oxygen use by micro-organism in the water. A curve drawn to represent dissolved oxygen levels down a stream from a point of effluent ...

WATER SUPPLIES IN GUATEMALA

I am going to carry out a project on water supplies in Guatemala. In my project, I will come up with strategies that will help in restoring clean water for these people. For effective results, it’s important to come up with ways that will help in crossing the barriers of language, culture, distrust, and fear so as to establish a healthy rapport with the community on study. What is water? I will start my project by defining this term. Water is, from academic definition, a gist that is colorless, tasteless and unscented. Through research, Fresh water is depicted as having ...

1.0 PURPOSE In the City of Flagstaff, there exists the Cheshire Pond and the Francis Short Pond. The Francis Short Pond is located south of the Cheshire Pond and is constantly being supplied with reclaimed water to maintain the water level while in the Cheshire has a constant supply of rainfall, snowmelt and is constantly being supplied by water from the Rio Del Flag. What raise many issues in the Francis Short Pond are the potential effects of the reclaimed water on the ecosystem around Francis Short Pond. Thus, to establish the differences between reclaimed water and as a source ...

Water is and has been one of the fundamental things that are necessary for the development and survival of all living things in the universe. This is why water has been regarded as an essential thing that supports the living in the universe. However due to many processes that water is used, the emergence of the wastewater is evident. Most factories in the globe use water do their processing. The water that is discarded after the processing is the one that is referred to as the wastewater and is usually unfit for human consumption. Wastewater is harmful and can ...

Introduction

Membrane filtration is a technique used to separate a liquid from any particles present in it. In membrane filtration, a liquid is passed through a semi-permeable membrane. The size of the pores on the membrane determines its permeability thereby enabling the membrane to act as a barrier to all particles larger than the pore sizes. Different approaches and systems can be employed in membrane filtration depending on the type and capacity of the liquid being purified but the overall goal is to obtain a clean liquid. Membrane filtration can be used in the treatment of wastewater, filtering milk during its processing among other applications. This ...
