Mini drum filter

Types of mini drum filters

Mini drum filters are available in different types to meet a wide range of needs and preferences. Each type has a unique function and importance in the operation of aquaculture systems and water treatment.

• Gravity drum filters

  Gravity filters work when waste water flows through an inclined cylinder, covered with filter media. The force of gravity causes debris to be trapped by the filter media, and then clean water flows out of the filter.

• Pressure drum filters

  Pressure mini drum filters use pressurized water to pass through the filter media and remove solid wastes. The filters are sealed and hold solid wastes until emptied through back flushing. Compared to gravity filters, pressure filters occupy smaller spaces and have greater filtration abilities.

• Drum screen filters

  Drum screen filters have rotating mesh filter screens housed in a drum-shaped container. Waste water flows through the rotating screens which capture solid waste. Then, the screens wash off the captured solids into a collection basin. The washing process makes drum screen filters to have uninterrupted filtration.

• Sieve filters

  Mini sieve filters use a fine mesh to capture solid particles from waste water. The filters can work with gravity or pressurized water. They have compact sizes but provide precise filtration for protecting equipment and enhancing water quality.

• Static filters

  Static filters have filter media that do not move. Waste water flows into the stationary filter media and solid waste is captured. While static filters have simple constructions and low costs, they require regular manual cleaning and maintenance.

Specification and Maintenance

Specification

• Material:

  Mini drum filters are typically manufactured using sturdy, corrosion-resistant materials, such as polyvinyl chloride (PVC) or stainless steel. PVC offers durability and lightweight performance, while stainless steel provides robustness and resistance to high temperatures.

• Drum Diameter and Length:

  The dimensions of the filter drum can differ according to applications. Commonly, the diameter ranges from 200mm to 1,000mm, while the length ranges from 500mm to 2,000mm.

• Aperture Size:

  The aperture size of the mini drum filter affects its filtration precision and efficiency. It usually ranges from 30 to 80 mesh. Smaller aperture sizes can filter more minute impurities but may result in a lower filtering speed, and vice versa.

Maintenance

• Regular Cleaning:

  Clean the filter drum at regular intervals according to the operating environment and water quality. Use a brush or high-pressure water pipe to clean the surface of the drum filter and pipeline attachments to avoid clogging and bacteria growth.

• Check for Damage:

  Inspect the filter's cylinder periodically to see whether it has any damages, such as cracks or deformation. Replace or repair the damaged components promptly to ensure the filtering quality and equipment stability.

• Check the Pump:

  Inspect the performance of the pumping apparatus regularly. Examine whether the connections are leak-tight, the operations are steady, and the filtering volumes are up to the expectations. Timely replace or fix the defective parts to ensure the effective and stable functioning of the whole filtering system.

• Disinfection:

  Carry out disinfection to the filter equipment periodically. Use appropriate disinfecting agents to clean the surface of the drum and the inner parts so that it can inhibit the growth of bacteria and algae, ensuring the wholesome water supply.

Scenarios of mini drum filters

Mini drum filters can purify water in aquaculture farms. Using these filters fosters the sustainability of marine life. They achieve this by removing solid waste before clean water circulates again in ponds and tanks. Recycling water reduces the operational cost of running the fish farming business.

Wastewater treatment facilities utilize mini drum filters to remove moisture from solid sludge. The drying process enables easy transportation and storage of the sludge. Mini filters also separate clean effluent that can be recycled in the treatment facility or released to nearby water bodies without causing pollution.

Industries that use cooling towers install mini drum filters to improve the quality of water used. The filters get rid of waterborne pathogens that could promote the growth of Legionella bacteria. They also remove particulate matter and microorganisms. Improving the quality of water used in cooling towers lowers the risk of system breakdowns and enhances efficiency.

Mini drum filters are valuable components in mechanical systems supporting hydroponic and aquaponic farming. They remove solid particles from water. By doing so, they protect water pumps, nutrient delivery systems, and grow media from clogs and contamination. Besides extending the life of farm equipment, mini drum filters create healthier systems for plant and fish growth.

Aquarium owners use mini drum filters to keep aquariums clean. They remove waste produced by fish and uneaten food to maintain water quality. Proper water quality reduces the risk of diseases that could threaten the life of aquarium pets.

The construction industry uses mini drum filters to separate and collect slurry during excavation processes. The filter collects soil while allowing water to flow through. It minimizes the impact of dewatering on the surrounding environment and prevents pollution. Keeping contaminants on construction sites protects nearby water bodies.

Landscape and golf course maintenance teams use mini drum filters in irrigation systems. The filters remove clogging materials such as sediments and algae. They allow the water distribution system to function optimally and maintain the quality of green spaces and lawns.

Industrial machining applications can use the mini drum filter to remove metal shavings from the coolant used during machining processes. Separating the shavings from the coolant can lower the cost of disposing of the shavings and recycling the coolant.

How to choose mini drum filters

Both the design and the function of the mini drum filter play a vital role in determining what factors to take into account when selecting them.

• Pond Size: There are certainly limits when it comes to growing fish or keeping them in a pool. The size of the pond will also determine what kind of waste there is and how much filtration it needs. Critical parameters like surface area and volume must be considered so that the selected filter can provide a bare minimum of 2-3 litres per litre of pond water per hour. Large filters that work in big pools can't be used, and small ones would overwork themselves to very little efficiency.
• Waste Processing: A drum filter's main job is to separate solid waste from water and keep the latter free for living creatures. The household pond may only need leaves, flower debris, and visitors to break down into probable solid waste. The business pond could have much larger organic and inorganic matter. Fine mesh filters, such as 600 micron drum filters, will be suitable for a pond with only fish and a poorly set up food chain, while 200 mesh mini drum filters will be suitable for large ponds with less organic matter. Even finer mesh filters with 50 or 200 mesh can be used in commercial ponds.
• Gravity-Driven: The entry of dirty water, the passing of clarity, and the exit of clear water become very important aspects. The filter can work by gravity, where a slope allows water movement without any mechanical force but only because of the positioning of the filter at a higher altitude than the discharge point. This arrangement is suitable for small filters situated uphill concerning the pond, and water pressure can help it clean effluents without pumps or wires.
• Pump-Driven: Larger filters with more organic pumps must use electrical energy to process more water to pass through the filter. In these pumps conveying dirty water can be at the filter's input, or the filter output may be chemically treated to ensure that electrically powered processing can take place.
• Material Durability: Plastic, stainless steel, and PVC filters are all available. Depending on where they'll be used and what temperature changes they might experience, materials that can withstand temperature changes and things like pond water and air humidity should be examined.
• Cost: Owners of ponds, whether businesses or households, have a budget. Filters that can work without a pump will be cheaper, and those that depend on a pump with more power will be costlier. Selecting factors that can be easily afforded, cost over the pool of life, and will help with long-term maintenance and expense is essential.
