High-Efficiency Filtration Solutions – From Stock Prep to Finished Product

In papermaking, puritas aquae et chemical consistency determine paper grade, equipment life and operating costs. From raw water to shower water to coatings, contaminant control is critical. CREST offers a full range – from coarse separation to precision automatic self-cleaning filtration – to solve grit, gels, lumps and more, enabling stable production, higher quality and lower costs.

Clavis Applications

Raw Water Filtration

● Processus

Filtratio prima in domo pompae aut in capite principalis, quae aquam puram e flumine, lacu vel rete municipali ad totum molinum suppeditat.

● Problema:

Arena, solida suspensa et microbia usum, obturationem dyspensarum et contaminationem posteros causant – quod maintenance et tempus non operativum augent.

● Solutio:

Filtrum automaticum se-purgans ut prima barriera particulas magnas removet, aquam puram continuam assicurat et omnes processus posteros protegit.

● Producta:

Filtrum Automaticum Se Purgans

Filtratio Lavacri Altae Pressionis Sectionis Filiformis

● Processus:

Filtratio finalis aquae lavacri altae pressionis pro purgatione fabricae formantis ad uniformem desiccationem servandam.

● Problema:

Residual fibres and fines clog tiny nozzles, leading to fabric plugging, sheet holes and shortened fabric life.

● Solutio:

High-pressure self-cleaning filter at pump outlet, just before shower header – delivers absolutely clean water, eliminates nozzle blockages.

● Producta:

Filtrum Automaticum Se Purgans

Felt Section High-Pressure Shower Filtration

● Processus:

Filtration of high-pressure shower water for continuous press felt cleaning to preserve permeability and dewatering.

● Problema:

Contaminants fill felt pores (“plugging”), reducing dewatering, raising steam consumption and requiring frequent felt changes.

● Solutio:

Same high-pressure filter at felt shower discharge – keeps water clean and felt in optimal condition.

● Producta:

Filtrum Automaticum Se Purgans

Ultra-Clear White Water (White Water Recovery) Precision Filtration

● Processus:

Final polishing of ultra-clear white water from DAF or disc filters before reuse in showers, dilution, etc.

● Problema:

Recovered water still contains fine fibres, fillers and stickies – worsening nozzle clogging, causing defects and limiting recycle ratio.

● Solutio:

Filtrum autonoma praecisionis altae in capite effluentis systematis recuperationis – meliorat qualitatem aquae, permittit recirculationem alti ritus.

● Producta:
Filtrum Automaticum Se Purgans

Systema Filtrationis Automaticum Multorum Unitatum

Filtratio Aquae Sigillantis Pumpae Vacui

● Processus:

Purificatio aquae sigillantis uti pro refrigerando et sigillando pumpis vacui (rotulis suctionis, rotulis couch, etc.).

● Problema:

Fibrae et plena in aqua sigilli impellentia et facies terminales laedunt – vacuum performance minuit et maintenance auget.

● Solutio:

Sese-purgans filtrum ante aquae sigilli introitum – solida removet, instrumenta rotatoria critica protegit.

● Producta:

Filtrum Automaticum Se Purgans

Filtratio Chemica

● Processus:

Filtratio amylaci coateris, latex, auxiliorum retinentium, agentium dimensionum, agentium fortitudinis umidae, colorum et aliorum chemicorum ante introitum systematis.

● Problema:

Gelae non dissolutae, grumuli, precipitata vel particulae causant strigas coateris, damnum cultri, inaequalem tincturam (maculas) et alia defecta – nocent printabilitati.

● Solutio:

Secundum viscositatem, temperaturam et contentum solidorum, elige filtrum aut sacculi, aut cestelli, aut rasorii seipsum purgantis ad impuritates removendas cum optima praecisione et minima deformatione – effectum chemicum servans.

● Producta:

Filtrum sacculi / cestelli	Filtrum rasorii seipsum purgantis
