Municipal Wastewater Treatment Anaerobic Digester Tank

Product Description:

A biogas plant is an anaerobic digester, often used to treat farm wastes or energy crops. It consists of an air-tight tank which contains different configurations. These plants can be fed with energy crops, such as maize silage, or biodegradable wastes including sewage sludge and food waste. Through the processes, the micro-organisms will then transform the biomass waste into biogas (primary being methane and carbon dioxide) and digestate.

Greater amounts of biogas can be produced when wastewater is coupled with other residuals, like dairy products, the sugar industry, or brewery product. For example, when mixing 90% wastewater from beer with 10% cow whey, the amount of biogas produced increased by 2.5 times in comparison to biogas originating from wastewater of a brewery only.

However, manufacturing of biogas from planted maize has been decreed to be unsustainable and harmful as a result of intensive and soil eroding characteristics of the plantations.

Features:

Anaerobic Digestion has played a key role in transforming wastewater treatment plants (WWTPs) into water resource recovery facilities (WRRFs). Generally, the "waste gas" by-product is capturing as biogas - a renewable, clean source of energy. In fact, some facilities have attained the capability to actually pump RNG into the pipelines and/or contribute to the grid.

Despite the considerable progress achieved in some areas, the essential setup of the anaerobic digesters for wastewater hasn't much changed since the early 20th century. Starting the anaerobic digestion process in the tank with an amalgam of primary and secondary sludge isn't a complex task. What's important is to keep the surroundings OXYGEN-FREE, HOMOGENOUS, WARM, and it won't take more than 15-20 days for the microbes to flourish, breakdown solids, and produce biogas.

Thus, it is explicitly demonstrated that COVERING, MIXING and HEATING the tank is of utmost importance in order to ensure compressed yields. By adopting the right type of digester cover, mixer, and temperature control system coupled with effective utilization, it is possible to mitigate operational challenges, inefficiencies and even major glitches.

Applications:

Food waste is one of the major sources of pollution and carbon emissions. The average global citizen produces nearly 170-225 kg of food waste annually. The majority of the food waste comes from households who often throw away food because it is uneaten or spoiled.

Straws often end up in oceans and can be difficult to remove. They pose a serious threat to marine life since they can be mistaken for food. Some companies, like Starbucks, have already taken initiatives to reduce their straw usage.

Chicken farms are also a major source of pollution due to the amount of feed that they require in order to maintain healthy chickens. The excess feed often ends up in waterways and can pollute the surrounding environment. Cattle and pig farms also contribute to water pollution due to the amount of manure produced.

Other livestock farms, such as sheep and goat farms, also produce large amounts of emissions. These emissions are mainly in the form of ammonia. Additionally, the livestock produce methane emissions, which are much more potent than carbon dioxide and are one of the major contributors to global warming.
