Removing Inorganic Substances - 3 Essential Components Of Wastewater Treatment
To understand the entire process of wastewater inorganic removal, you will have to first have to understand its various components and concepts. The inorganic substances that are dissolved in any water source are both common to waste as well as natural water. Determining what components are organic and what are inorganic is the first step towards establishing and controlling the quality of the water. Some different concepts and factors should be considered here, including wastewater bar screen, sludge screening system, and fat, oil and grease screening. The following section attempts to make these concepts simpler for the reader:
1. Wastewater Bar Screens
The very first few aspects that you will have to take care of when determining the screening equipment for your wastewater treatment plant are the existing channel dimensions and the hydraulic profile. You will have to assess the existing downstream water level and what factors control it. There might be certain upstream water level limitations as well. You will also have to keep in mind certain guidelines for velocities of the water when it approaches the screen and when it moves through the screen grid.
The wastewater bar screen should be able to fit physically as well as hydraulically into the waste water treatment plant. There will be certain limitations on the space for a screen as well. This means that both the head room and angle of inclination will first have to be decided upon whenever you are choosing a wastewater screen for your treatment plant.
2. Sludge Screening Systems
Sludge screening systems are also a very essential part of any wastewater inorganic removal treatment plant. The purpose of this screening is to remove any large and potentially harmful solids from the wastewater stream. Before the water is further treated, these solids are removed very carefully so that they do not enter the treatment equipment and cause them unnecessary damage. This is a way to prevent any potential wear and tear to the equipment and save more time that would otherwise go into repairs and fixes of the same if you are not careful.
3. Understanding Oil And Grease Analysis
Fat oil and grease screening is also a very important aspect of inorganic substance removal from wastewater sources. This category of substances includes oils, fats, and waxes and various other constituents found in water. Removal of these compounds is very essential because these can interfere with biological life in surface waters as well. When left unattended these substances can create unsightly films and covers on the surface of the water. All the domestic wastewater that is accumulated in these treatment plants has some kind of oil or fat content in them which can be butter or margarine, lard, and vegetable fats.
Several other items that contain fats are various kinds of meats and poultry, germinal areas of cereals, certain fruits, nuts, and seeds. Tar and various lubricating oils and several petroleum products are also found in wastewater sources. These oils reach the sewers in considerable volumes and should be treated as soon as possible. Some mineral oils can form harmful coatings over the water which can be very difficult to remove and result in interference with the natural biological processes. They may also cause severe damage to the machinery if your wastewater treatment plant is not equipped with the right components and parts to treat and remove these substances.
