BOLLFILTER filtration in the paper industry

BOLLFILTER systems have proven their value in many paper application processes, such as the filtration of raw water, sealing water, process water and cooling water. Mill owners have chosen them thanks to a history of exceptional reliability and their minimal maintenance requirements.

Spraying nozzles protection in the paper industry

One of the most common applications is in the shower water processes where the filters protect the shower nozzles. Automatic filtration ensures paper mill keeps manufacturing at maximum rate. Installed in the shower supply line, they prevent clogging and resultant costly downtime and loss of production. BOLL & KIRCH has supplied dozens of BOLLFILTERs Automatic Type 6.18 for shower water applications, with a proven performance of 24 hour protection with a normal annual service interval.

Reference in the paper industry for spray nozzle Protection (UK Paper Mill UPM Shotton)

UPM Shotton has installed an BOLLFILTER Automatic system to provide fine filtration of wash water. Today more than 600,000 tonnes of waste paper is collected and recycled each year – saving landfill space and avoiding the need for incineration. 

During the manufacturing process, waste water goes through a complex process of treatment, clarification and filtration before recycling or pumping back to the river. The recycled water is used as wash water, sprayed through nozzles to clean sludge from equipment used to produce fertiliser or fuel cakes. UPM Shotton has installed an BOLLFILTER Automatic system to provide fine filtration of wash water. 

Raw water filtration

Raw water filters need to be reliable, accurate and as maintenance free as possible. BOLL & KIRCH filters quite rarely need spare parts during their first ten years of operation. BOLL & KIRCH filter candles are made of titanium alloy stainless steel. Raw water filters are very important components in a pulp or paper mill's process system. Defect free operation is essential.

Reference for recycled water in the paper industry 

UPM-Kymmene Tervasaari rebuilt its raw water treatment and pumping system, installing two BOLLFILTER Automatic systems as mainstream filters to ensure the quality of water supply to the plant. The BOLLFILTERs, which are fully integrated into the Distributed Control System (DCS), have reduced the power consumption of the pumping systems, thanks to the very low clean pressure drop afforded by the large filtration area.

Sand filter police filters

Sand filters quite often release some sand particles and they need to be filtered out before they go to production. Sand particles are easy to remove with BOLLFILTERs. Due to the large filtration areas, BOLL & KIRCH filters are very economical since the sand filtered and/or chemically treated water is expensive. The loss of water during the flushing is usually a couple of seconds total flow a day. BOLL & KIRCH filter candles last for decades in these applications.
