If your company has been making plans to upgrade its septic system, you will need to determine whether an aerobic or anaerobic digester is the better investment. Determining which septic parts in Bethel, OH are best suited for differing levels of industrial use is not an easy task, but the following guide will help you understand the differences in the systems, and help you weigh the pros and cons of each.
Aerobic digesters
Aerobic digesters introduce oxygen into the digestion tank to produce enough bacteria to break down and remove the solids in the wastewater. These types of digesters are commonly used because they have much smaller upfront construction and installation costs, and typically experience fewer significant malfunctions during operation. Unlike aerobic digesters, these tanks do not contain the harmful metals that can inhibit the treatment process and subsequently hinder the ability of the waste to be used as fertilizer. These metals can also be toxic when large amounts are released into the atmosphere, and could potentially cause serious health issues for those who might come into contact with them.
One of the drawbacks of the aerobic digestion system is the size of the tanks. Since there are several internal aeration components that have to be included, the tanks are large and require a substantial amount of land for installation. So while the construction of the actual tank may be cheaper than that of anaerobic tank, a lot of the remaining budget will have to be assigned to land and energy costs.
Anaerobic tanks
If your company is looking to be more environmentally conscious, an anaerobic digester might be best for your business. Anaerobic digestion tanks operate without the presence of oxygen and other additives, and as a result the waste is able to be broken down into useful compounds. Anaerobic tanks also produce fewer solids and require a lot less energy due to the absence of the equipment that carries out the aeration process in aerobic digestion.
In addition, these tanks produce methane, which is a by-product that can be recycled and used as a fuel source. Although the construction costs of anaerobic digestion tanks exceed those of their counterpart, the operating costs during the life of the system will be much lower. Because there will be fewer solids remaining after the process has been completed, your company will be able to save a substantial amount of money annually on disposal costs.
However, because these tanks are smaller than aerobic tanks, the temperature range is limited and additional processes might have to be added in order to heat the tank to the necessary operating temperatures. These tanks also see a higher level of contaminants and metals in the sludge, and the aggressive removal procedure will add to the monthly operating costs.
