Waste Digester Storage Tanks – Waste digesters, most often anaerobic digestion, break down and recycle organic material. They are used to capture the biogas produced by the anaerobic bacteria. That biogas can be turned into a renewable energy.
There are different forms of waste digesters. Each one is slightly different. But, all are designed to breakdown and recycle organic materials
What industries can use waste digesters?
- Livestock operations due to the animal manure
- Sewage water and wastewater plants
- Food and beverage processing that creates whey, beer waste, glycerin and unconverted oils, and distillery waste
These digesters not only provide a renewable energy source. But, help reduce greenhouse gas like methane. That is because they are closed systems.
Waste digesters can be large or small. Whatever the size they will need biogas storage tanks and storage tanks for farms.
As this field of renewable bioenergy has emerged, the storage tanks for it, have been improved. We will look at some of those tanks a little later.
What can the biogas produced from waste digesters are used for?
What can the biogas that is produced from waste digesters be put to use for? This renewable energy has a few uses. These include:
- Heat buildings
- Fuel transportation
Each of those uses requires a different process to work. For example, transportation fuel requires cleaning and then put into the pipeline.
There are federal rewards for renewable shipping fuel companies. The rewards get companies to inject their biofuel into the natural gas grid.
Fuel for transportation must also meet renewable fuel standards developed by the EPA. Biogas for fuel must meet the requirements. If it does not it cannot be mixed with fossil fuels or injected into the pipeline.
Companies can purchase Renewable Identification Numbers that will identify renewable fuel. The RINs can be purchased and sold separately from the fuel itself. They help the EPA track and enforce the renewable fuel standards.
California has a separate standard called Low Carbon Fuel Standard. It works similar to the renewable fuel standards. It states the gas from other states that do not qualify for Golden state credits must be sold to a company with distributing services. Or a company with a vehicle fleet in California.
However, biogas that is used on site for heating or electric does not have to qualify for the Renewable Fuel Standard or Low Carbon Fuel Standard. But, it also does not create RINs or credits in California.
Other benefits of biogas
Other benefits of biogas include:
- Saves farmers money by using the fertilizer from the digester the soil is healthier and improves crop yields.
- Reduced dumping of sludge in landfills
- It keeps streams, lakes, ponds, and other bodies of water cleaner.
- Healthier soil means less irrigation, less nutrient runoff, and a reduction in soil erosion.
- Digesters have the ability to increase the grid’s reliability. Also, reduce electric costs to everyone, and lower the requirement for electric.
Biogas from farms, city wastewater, and food processing plants can reduce the need for fossil fuel by about 5%. As more is produced from these methods and others, that number may increase. Reducing greenhouse gases is a benefit to the planet. It provides cleaner air, reduction of storms caused by climate change, and more.
Storage tanks for biogas
The storage tanks for biogas, like the storage tanks for farms, are specially designed. They are built to meet all local, state, and federal requirements. Those requirements include CBC2016 and AWWA, NSF 61, and NFPA 22.
These tanks are available in a wide range of capacities up to 5,000,000 gallons. These tanks will fit any size farm biogas plant. They will work for a number of things such as:
- Storage for the organic materials for feeding the plant
- Fermentation tank
- Gas storage tank
- A tank for the fertilizer that is left
Types of tanks to choose from
There are several tanks you can choose for you farm biogas needs.
- Corrugated bolted steel tanks will work well for irrigation. Also for wastewater, drinking water, fire prevention, biogas tanks and more. These tanks come in sizes from 722 gallons to 651,777 gallons. The flexibility of the capacity makes them perfect for storage tanks for farms and biogas plants.
- Bolted Steel Tanks uses include storage of numerous types of liquids. Those liquids are used in commercial manufacturing. But also for drinking water, waste water, bulk materials and dry goods for industries. These tanks work well for bio-solids, sludge, fire protection, wastewater, and more. They range in capacity from 4,000 gallons up to 2,868,000 gallons. Another tank that is perfect to use for storage tanks for biogas.
- Stainless Steel Welded Tanks these are single wall or double wall tanks that are a perfect solution for fermenting tanks. They are perfect for chemical and fertilize storage tanks for farms or biogas tanks. The size ranges from 100 gallons to 650,000 gallons.
- Glass Fused to Steel Tanks technology is truly the ultimate solution. It can be used for bio-solids, drinking water, bulk materials, and wastewater. The size provides a range from 4,000 gallons to 2,868,000 gallons, so they will work for medium to larger sized farms and biogas plants. One of the best solution for storing liquids manure, dung water, liquid fertilizers and other chemicals within the range of chemical endurance of enamel.
- Welded Steel Tanks are the ideal tanks for fire prevention for agricultural and small commercial business for biogas plants. The size ranges from 5,000 to 30,000 gallons.
- Underground Fiberglass can also be used to store grease, chemicals, gasoline, sludge, petroleum products, as well as separators and interceptors. Also, they can be a good solution for underground storage of drinking water, wastewater, fire protection, and storm water.
Once you have your biogas plant design, tanks and the permits you need, you can build your farm biogas storage.
Remember each tank is custom-made to meet the conditions of your storage tank needs for farming and biogas. Just provide us with the size tanks, what they will be used for, and how you plan to install them (above or underground) and we will build them exactly for your project.
