Engineering Vasai East, Palghar, Dist. Capacity : 40l Mono-Block Pump : no. Technology Exchange Services Pvt. Aerobic Digester Get Quote. Solid Waste Digesters Ask Price An anaerobic digester is a tank or vessel which excludes oxygen and in which a sludge or a liquid effluent is modified by the action of anaerobic bacteria. Organic material in the effluent is converted to methane and carbon dioxide bio gas and the BOD and COD value of the effluent is reduced.
The bio gas can be used to heat. Sun Enviro Technologies Pvt. Anaerobic Digester Get Quote. The effluent is first passed.
These digesters provide a large volume hydraulic retention time: 45 days , offering better process stability with consistent. Hybrid Anaerobic Digesters Get Quote. Anaerobic Digesters Ask Price We provide good quality Anaerobic Digesters that is a tank or vessel used to exclude oxygen.
In this product sludge or a liquid effluent is treated by the action of anaerobic bacteria. The Organic material present in the effluent is transformed in to methane and carbon dioxide bio gas thereby reducing the BOD and COD value of. Krishna Gangaa Enviro System Pvt. Sludge Digester Ask Price We have achieved paramount success in trading and manufacturing of Sludge Digester in the market at the present scenario. Anaerobic digestion is a biological process which breaks down a significant amount of organic solids in the sludge and at the same time produces methane gas that is used as a boiler fuel for plant heating.
Anaerobic Digester Ask Price Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. It is widely used to treat wastewater and organic waste, yielding biogas containing methane.
This document should be considered a screening tool as to whether or not an anaerobic digester could be economically feasible at your operation, and whether or not it would be useful for you to conduct a detailed financial analysis. Costs vary, depending upon the size of the unit, design, and features. The type of anaerobic digester necessary for your operation and therefore the cost of the anaerobic digester varies according to the number of livestock and technical considerations like temperature.
Annual operation and maintenance costs like maintenance, repairs, parts, labor, and insurance , must also be included when considering the cost of an anaerobic digestion system. The Ag Star website is updated frequently with information about federal and state funding opportunities for anaerobic digestion projects as well.
Because of the capital-intensive nature of anaerobic digestion, it is recommended that you thoroughly understand the parameters of any funding programs prior to investing in a digestion system. You may wish to discuss any loan risk associated with a methane digester with your agricultural loan officer to ensure that additional debt will not compromise your ability to access capital for your existing operation.
As part of economic analysis, you should determine the extent to which you will offset costs by generating revenues or reducing energy expenditures over the life of the digester. Utility contracts can vary considerably throughout rural communities. However, the value of this offset will vary by utility. Some utilities will credit net-metered power at the retail rate, meaning that there is a direct offset for every kilowatt-hour of electrical production.
Other utilities credit net-metered power at a discounted or wholesale rate. In the case of agricultural operations, you may be assessed a demand charge for electricity. Demand charges are not usually offset in net metering, but can comprise up to half of your electrical expense.
Check with your utility regarding their net metering policy. In order to increase profitability, producers should focus on reducing operation and maintenance costs, as well as offsetting energy usage with the anaerobic digester system. Producers should be wary of relying on anaerobic digestion to generate revenues by selling electricity to the utility. You should discuss this concept with the utility.
Be aware that the utility may not be willing to purchase the power. If they are willing, be aware that the price offered is typically a wholesale price.
You should also check to see if there are contractual terms that might be problematic for you. Some utilities require a guaranteed amount of power be supplied in a given time period. Others require notice of changes in electrical production.
These considerations should be taken into account as you consider possible revenue generation from anaerobic digestion power sales. While you are in the process of selecting a digester technology, you should outline some of your expected costs and revenues over the life of the digester. Once you contact a technology provider, you can obtain the more detailed information necessary to compute actual costs.
They supply enough energy to power the equivalent of over 11, homes. However, the economic return for smaller plants has diminished with the tapering-off of the government Feed-in Tariff or FiT due to end in and changes to the Renewable Heat Incentive RHI. The digester chosen can significantly affect the cost, so farmers should look carefully at the options. Costs can also be saved by using existing farm machinery and labour for civil works. Another way to cut expenditure is to use a flexible tank or slurry lagoon cover instead of a metal one.
Several companies supply different versions of these. As the electrical grid and gas grid options become less viable [because of the lower tariffs], smaller AD operations that utilise locally produced waste for local uses with low capex may well become more viable. A combined heat and power plant CHP uses the biogas to generate heat and power.
But all sources we spoke to advise that costs can be saved by not using CHP. Some advisers advocate upgrading the gas to the quality needed for use in a vehicle or to pump into the National Grid. But, again, this will incur extra costs. A simpler, cheaper small-scale solution is to burn the gas in a boiler for on-site use, including for the small proportion of generated heat that is required to kick-start the digester to process the slurry.
Financial viability depends on whether it can offer a long-term improvement in farm efficiency at no greater cost per cow than the current system of slurry storage. This will significantly reduce the current cost of installation, with low maintenance costs, and can be easily adapted to fit any of the possibilities. In this case, using digested slurry on their farms can cut costs.
The challenge of diffuse pollution is driving change, says Bull. Since raw slurry has a higher oxygen demand than does digested slurry then relatively inexpensive options exist for converting a slurry store into a digester. A policy that supports AD would encourage the fastest shift to sustainability and innovation in the AD sector.
