Function

This type of filtration comes with 100% immersed disc design involving different type of filtration cloth than used on conventional 65% immersed disc filters. Cleaning process involves suction instead of backwashing, so the impurities are caught from the outside in this case. Exceptional filtration results can be achieved even with the combination with our FDi and FDGi filter series.

Principle

The untreated water including the impurities flows into the filter pit. There is a filter including the filtration cloth on the segments, which forms individual discs. Whole system is 100% immersed. Water passes through the filter cloth inside the hollow shaft retaining the impurities on its surface.
We offer the filter in size 2.2 m.
Filtration runs continuously.

Advantages

• continuous filtration even during the backwash
• high capacities on small footprint
• higher filtration area per disc
• lower power consumption during backwash
• low operational cost
• possibility of sedimentation in the filter pit
• no aerosol pollution during backwash cycle
• exceptionally low noise pollution
• long span life of filtration cloth – doesn´t threat to tear the cloth

Variability

• depending on location – in concrete channel or steel tank
• depending on the required quality of filtered water
• depending on the sludge discharge method – by gravity or by pump

Pile cloth filter – „ORSO“

Function

“CLEVER” Disc filters are designed for filtering large volumes of wastewater with high demands on the quality of the treated water.
Thanks to more than 15 design improvements, the “CLEVER” Disc filter is the ideal solution for modernizing existing systems and applications, even in space-constrianed environments.
They are used for treatment of effluent water, as pre-treatment before UV, pre-treatment of potable water, in fish farms and Koi ponds, in the Pulp and Paper industry, and also in food processing, for inlet process water, cooling water in various industries, or for the recovery of valuable materials in different types of industry.

Principle

The basic filter element is a filter segment covered with filter cloth. Water flowing into the interior of the filter segment flows through the filter cloth to the outside, where fine impurities are trapped on the filter cloth. The segments are mounted on a disc shaft. Twelve segments form one disc. The number of discs determines the capacity and thus the size of the filter.

Filtration runs continuously without interruption. Reliable filter for high substance loads.

Advantages

• extremely low backwash water and power consumption
• low maintenance costs resulting from a robust and well-thought-out design
• gravity flow saves energy costs

Variability

• depending on the required filter capacity
• depending on location – in concrete channel or steel tank
• depending on the required quality of filtered water
• depending on the sludge discharge method – by gravity or by pump

Drum screw filter

This design of microscreen drum filters is very durable and sophisticated. The development team, which is dedicated exclusively to microfiltration, has extensive experience, as evidenced by the fact that by the end of the year, the number of micro-mesh filters produced will exceed 1,200 worldwide. We are thus one of the leading manufacturers of microfiltration equipment in the world.

The overall design of the device emphasizes the long life of the filter and minimal wear of individual parts. IN-EKO micro-sieve drum filters are made exclusively of stainless steel and high-quality technical plastics.

Each application requires an individual approach. Therefore, there are several variants of the device.

• model range according to the needs of the hydraulic load
• placement in a concrete channel or above ground
• level with connection to flanges

• the density and material of the filter cloth can be changed
• sludge outflow from filtration can be done by gravity or sludge pump
• different control methods and degrees of automation
• entire blocks of micro-sieve filters can be easily operated

Water containing solid particles flows through a supply pipe or channel into the interior of the filter drum, impurities are trapped on the inside of the filter cloth and the purified water flows out through the cloth. During this filtration process, the entire filtration device is at rest (it does not consume any energy). The filter cloth becomes clogged with gradually flowing dirt, the resistance of the tarpaulin to flow increases and the water level and hydrostatic pressure inside the drum increase.

When the set level in the inner part of the filter drum is reached, the level probe automatically switches on the drum rotation drive and at the same time the rinsing pump, which pumps the filtered water to the nozzles of the rinsing system. The precisely directed stream of water, sprayed by special nozzles, entrains the dirt trapped on the inside of the fabric into the waste chute, which is located inside the drum. The sludge flows into the sludge sump and is pumped out by a sludge pump, which is also automatically controlled by a level probe located on the wall of the sludge sump. With the possibility of gravity sludge outflow, the sludge pump is omitted. At the end of the flushing process, the level in the filter drum drops and its drive and flushing pump are switched off. The device is at rest. The process is repeated.

No additional holding tanks for backwash water or sludge water are required for the plant, because the raw water supply is not interrupted during the rinsing process and the rinsing water is taken directly from the filter plant, which leads to a significant reduction in investment costs. The sludge sump is an integrated part of the device.

By automatically switching the filter on and off, power consumption is minimized. energy, the average quality of the filtered water increases, the density of the effluent increases and the service life of the entire plant is extended.

If the micro-sieve filter is inactive due to a power failure, the filter cloth will completely clog over time and the water will rise to the emergency level. In this case, the water is drained, leaving the remaining filtered water clean. After eliminating the cause of the device’s inactivity, it is possible to start filtering again without any intervention in the machine. The flushing pump has enough clean water to perform a high-quality flushing of the filter cloth. The device returns to the original cycle.
