CHAPTER 6 PRETREATMENT AND CLEANING Pretreatment and cleaning are two independent processes that could also be related to each other at the same time. Such methods are crucial for seawater reverse osmosis for what they bring from cost and residence time reductions to the increase in the production quality. 6.1. Pretreatment Various pretreatment methods are used and they include: biofilter‚ subsurface intake systems‚ conventional treatment‚ biological activated carbon‚ and chlorine injection.

Exam Review – January 2013 Diversity Unit - List taxonomic ranks in order. What is the significance of this order? Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ Species. Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example

The Effects of Snails and Elodea in Water on Carbon Dioxide Levels Problem: How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide? Background: This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms‚ whether it is given or released through that organism. Both plants and animals
