BOLLFILTER Automatic Type 6.03 AOT The 2-in-1 solution for water filtration, backwashable and with UV disinfectionMarine

The 2-in-1 system for water filtration and disinfection
Besides of being contaminated with particules, industrial water which is heated or cooled is also often contaminated with potentially harmful microorganisms.

The BOLLFILTER automatic Type 6.03 AOT offers a combined solution for water treatment. Two stages in one unit ensuring an efficient continuous filtration as well as the disinfection of the filtrate.

The concept of the BOLLFILTER Automatic Type 6.03 AOT
The filtration stage is maintenance-free with automatic backwash boosted by a vortex compressed air system.

The disinfection stage is effected without any chemical additives (biocides) by means of photocatalysis, the AOT-method (Advanced Oxidation Technology).
To make the photocatalysis procedure possible, the surface of the filter element in the BOLLFILTER Automatic Type 6.03 AOT is coated with a catalyst.
When this surface is exposed to UV light, reactive radicals are formed, which oxidise the impurities contained in the water.

Applications of the BOLLFILTER Automatic Type 6.03 AOT
The filter is used for the filtration of cooling water, washing water, effluent, irrigation water, domestic water or hotel-swimming pools.

A further application is in the drinking industry for tunnel pasteurisers, where the BOLLFILTER filters and disinfects the warm water used to pasteurise drinks like juice or beer.

Ballast Water Filter BOLLFILTER Automatic Self-Clean Type 6.18.3, online backwashingMarine

Ballast water management system is obligatory on ships
Treatment of the ballast water should prevent further invasive pollution of the coastal installations due to foreign water organisms that threaten the marine ecosystems.

Protection of the ballast water treatment system
Aggressive seawater, tenacious adhering organic particles and mussel growth, inside and outside the ballast-water treatment systems affect their optimum functionality. Through reliable prefiltration, using the BOLLFILTER automatic Type 6.18.3, solid protection for the ballast water system is ensured.

Cost savings through a fully automatic filter
Due to automatic backflushing, perfect regeneration of the filter mesh is ensured. The filter, operating fully automatic, conforms to the regulations of unsupervised operation on ships. A continuous series with different sizes of housing and nominal connection widths, permit adapted dimensioning of the ballast water filter to individual circumstances.

BOLLFILTER Automatic Type 6.21/6.22 Cost-effective fuel oil filterMarine

The BOLLFILTER Automatic Type 6.21 has been especially designed for the filtration of lower and continuous filtration volumes of liquid fuels. The filter operates predominantly for the protection of diesel injection pumps. When required, the media is cleaned one segment at a time by a rotating backflush unit, without interrupting the filtration process. The working pressure remains almost constant and the flushing volumes are extremely low. The filter can optionally be equipped with a heating medium connection on the bottom of the housing and with a bypass filter.
