Welcome
Congratulations to your new Combi Drum Filter (CDF) !
Water filtration is a crucial aspect of maintaining clean and safe water for various applications, including drinking, industrial processes, and aquaculture. With the increasing concerns about water pollution and the need for effective filtration methods, the YCM Combi Filter has emerged as a comprehensive solution. This article aims to explore the features and benefits of the YCM Combi Filter, which combines a rotary drum filter, bio filter, and UV lamp, along with the use of a 75-micrometer filter screen, an 30W-60W UV lamp, and filter cotton.

Introduction
Description and Function of the CDF
The Combination Drum Filter is the symbiosis of all our experience in the area of mechanical and biological filtration, resulting in a “Turn key” solution: you just connect the inlets and outlets to your pipeworks and connect the power plug.
Instead of using traditional brush to filter fish feces, residual leaves, residual bait and other particles, use microfilter to filter particles smaller than 75 microns.
How CDF Works
Drum filtration part: Untreated water from the fish pond enters the YCM Combi Drum Filter through the water inlet (9). The water flows into the collection chamber (A) and then into the interior of the filter drum (5). Through a stainless steel screen (standard 75micron/200 mesh) outside the drum, all particles larger than 75 microns remain inside the drum and the water filtered through the screen leaves the drum filter chamber.
UV sterilization part: The water enters the UV lamp chamber (D) after the drum filter chamber, where the UV lamp can sterilize the water and effectively inhibit the growth of bacteria and green algae.
The water sterilized by UV lamps enters the biofilter chamber (D). The heart of the bio media filter lies in its biological filtration. As the water flows through the bio media, it is exposed to a vast network of beneficial bacteria that colonize the media’s surface. These bacteria, known as nitrifying bacteria, convert ammonia (toxic to fish) into nitrites, and then into nitrates.
Automatic flushing function: The waste particles left in the drum during filtration of the rotary drum filter slowly clog the filter screen, reducing the amount of water passing through the screen. As a result, the water level in the collection chamber (A) rises. Once the water level touches the level sensor (2), causing its float to float up, the rotary drum filter initiates an automatic flush.
The water level difference during flushing can be set manually by adjusting the height of the level sensor. When you clean the YCM Combi Drum Filter chamber, you can use the sewage outlet (11) to drain all the water inside the equipment.

Safety instructions
This system may cause bodily harm or damage to property if you do not use it properly and in accordance with all safety guidelines, or if you attempt to use it for any purpose other than that for which it was designed. This system must never be operated by children or anyone under the age of 16, or by anyone who has a physical, mental or sensory impairment or lack of experience and knowledge, unless they are under supervision and have been instructed on the safe usage of the system and informed of the dangers associated with it.Children must be made aware that this system is not a toy, Cleaning and maintenance must be performed by an adult user, This must never be performed by a child, even if they are under supervision
Important Notes
1 . As the CDF in running model will be filed with water, it is important that it is placed on aflat surface supporting the combi drum filter.
- Before CDF operation, please make sure there is more than one-third water inside the CDF tank to ensure the backwash pump does not idle.
- Check the health of the backwash nozzle, whether there is debris clogged in the nozzle and whether the screws are slack.
- Note! Electrical shock hazard
* Always switch off the current to the system before coming into contact with the pond water.
*Secure the system to prevent it from unintentionally being switched on.
*Never connect the system to a power supply that is fitted with a dimmer.
*Do not use the system in combination with a switch that has a timer function.
*Only switch on the control box if the pump is below the water level and the electrodes are below the surface.
Installation
Pump-Fed System
Place your drum filter on a solid surface that is completely level. You can then connect the inlet pipe from your pump, followed by the outlet pipes. The water will be pumped into the filter by the pump. Exits that are not used must be sealed.
In this case, you will need to assemble the float upside for the drum section (at the inlet)collection chamber.
lf the float is in the lowest position, the system is in standby. lf the float is in highest position (float is floating) then the process will commence (drum will start rotating and the rinse pump will spray-clean the screen). This will last for 9 seconds (standard value).
Probe:
Pump-fed arrangement, not flush situation, probe is dry
Pump-fed arrangement, flush situation, probe touches water
*Light blue is unfiltered water.*
*DarkBlue is filtered water.*
Media Maintenance
1.Rattan cotton biochemical filter cotton
Biochemical filtration rattan cotton role: can filter impurities, high density water permeability, strong cultivation of bacteria,fine drop structure is the breeding hotbed of nitrifying bacteria, through the parasitic nitrifying bacteria to remove harmful substances.
Rattan cotton biochemical filter cotton can be self-cleaning, flush the sediment attached to the filter cotton,cleaning interval is generally 2-3months. 1 year to replace the filter cotton.
1.Bacteria House
Bacteria house is mainly biological filtration,which can cultivate nitrifying bacteria, adsorb impurities and harmful substances in the water,increase dissolved oxygen in the water, and can convert ammonia nitrogen into nitrate.
It is recommended to replace it once a year.
3.Bacteriophage Biochemistry Balls
Bacteriological ball can provide a large number of nitrifying bacteria and other beneficial bacteria bed cultivation, improve the biochemical filtration effect and stabilise the water quality. It can evenly distribute the water flow in filtration and promote the rapid oxidation and reduction of organic substances.
It is recommended to replace it once everysix months.
