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 BOLLFILTER Automatic for shower water applications, with a proven performance of 24 hour protection with a normal annual service interval.

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.

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.
