Welcome to PARSWOOD™ store
Explore how filtration fits your product, your production line and your quality targets. Start with an application, follow its process map, then review suitable PARSWOOD product families.
Discuss Your Application ↗Selection starts with the process. These representative routes support an application discussion. Final grades, operating limits and microbial claims require the exact filter documentation and a validated process. They are not customer case studies or a complete food-safety plan.
Build the filtration train around the wine’s condition at bottling. A clear appearance alone does not establish good membrane filterability. Residual colloids, fining material and crystals can shorten a final filter’s run; residual spoilage organisms can compromise packaged wine.

Conceptual bottling route. Cellar clarification, protein stability and tartrate stability require separate process decisions. Polishing can be omitted only when the wine and subsequent filtration performance justify it.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Polishing | Reduce residual colloidal and particulate loading. | Lenticular depth media; select by wine trials, not by a nominal micron number alone. |
| Membrane protection | Intercept remaining particles before the final stage. | Pleated PP; a 1 µm candidate can be evaluated, with actual throughput measured. |
| Final filtration | Address defined spoilage-organism targets immediately before filling. | PES or N66 membrane candidates. Common wine grades include 0.45 and 0.65 µm; retention validation determines suitability. |
Record wine style, pH, alcohol, residual sugar, turbidity, filterability, batch volume and filling rate. Review integrity testing, sanitization and the condition of all equipment downstream of the final filter.
Candidates for technical evaluation, not confirmed interchangeable replacements.
Wine filterability and grade-selection review: use the printable process worksheet. Product links above provide current published specifications. Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Choose filtration to suit the beer style and preservation strategy. Bright beer, deliberately hazy beer and bottle-conditioned beer have different objectives. Removing yeast or haze indiscriminately can change the intended product.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
This map illustrates a clear, non-pasteurized beer route. A trap stage is especially relevant after DE filtration. Pasteurized, hazy and bottle-conditioned routes need their own assessment; final membrane filtration is not universal.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Trap and polishing | Capture residual solids or filter-aid carryover. | PP cartridges or lenticular media, selected against the incoming load. |
| Prefiltration | Reduce the fouling load reaching the final membrane. | Evaluate pleated PP or an appropriate depth stage using beer trials. |
| Cold microbial filtration | Support the specified packaging stability strategy. | PES is a candidate only after beer-organism retention, cleaning and sensory performance are reviewed. |
Assess yeast load, haze target, dissolved oxygen, carbonation, temperature, differential pressure and run length. Qualify tank vents and process gas separately. An industrial liquid cartridge is not automatically a sterile gas filter.

Beer clarification and packaging review: use the printable process worksheet. Product links above provide current published specifications. Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Separate visible-particle removal from chill-haze treatment. Barrel debris, carbon fines and infusion residues call for particle control. Haze that appears after dilution or cooling may need a different media mechanism and a product-specific conditioning step.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
The optional haze-treatment stage is selected by trials at the intended proof and storage conditions. There is no universal chill temperature. Carbon treatment is a separate optional formulation decision, not a default step in every spirit.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Particle removal | Remove solids without confusing them with dissolved haze precursors. | Pleated PP or depth media; choose retention to match the observed particles. |
| Haze treatment | Evaluate depth adsorption alongside clarity and sensory impact. | Lenticular media are a candidate format; specific chill-haze performance remains to be demonstrated. |
| Optional adsorption | Investigate unwanted colour or odour where the recipe permits it. | Carbon media require bench trials and downstream fines control. They can also remove desired characteristics. |
Provide alcohol concentration, temperature, haze behaviour after dilution/cooling, colour and sensory acceptance criteria. Verify the compatibility of media, seals and housing with the actual spirit and cleaning regime.

Spirits haze and adsorption trial brief: use the printable process worksheet. Product links above provide current published specifications. Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Start with the source-water analysis and the intended water category. Suspended solids, dissolved constituents and microorganisms require different controls. A cartridge filter for particles does not, by itself, correct dissolved salts or all chemical contaminants.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
RO, UV, ozone or other treatment may be used only where appropriate to the source and product specification; this map does not prescribe a universal treatment sequence. Natural mineral water requires a category-specific treatment review.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Source-water particles | Protect storage and downstream equipment. | PP cartridges; high-flow formats can be considered for larger utility flows. |
| Final membrane protection | Limit fine-particle and colloidal fouling. | Select PP pretreatment through feed analysis and run testing. |
| Final membrane | Provide the specified microbial barrier. | PES or N66 candidates; 0.22 µm availability is not proof of suitability or equivalence to a different rated filter. |
Specify source analysis, seasonal variation, flow, sanitization chemicals and target organisms. Final-filter integrity testing and hygienic filling must work together; test results are part of the release programme.

Bottling-water filter selection review: use the printable process worksheet. Product links above provide current published specifications. Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Bottling is the end of several converging streams. Treat water, sweetener, flavour ingredients and process gas according to their individual risks before they enter the finished beverage. The final filtration decision depends on the formulation and preservation route.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
Ingredient filtration occurs before streams combine. A clear beverage may support a membrane stage within its validated route; an emulsion or pulp-containing drink may not. Thermal and other preservation arrangements can change the sequence.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Water and syrup preparation | Control incoming particles before blending. | PP for compatible particles; lenticular media for suitable liquid clarification. |
| Flavour / concentrate filtration | Remove unwanted solids while retaining the intended formulation. | Trial depth or PP media; verify colour, flavour and ingredient recovery. |
| Final product protection | Match filtration to the selected preservation strategy. | Consider a membrane only for filterable formulations and a documented microbial target. |
Provide formulation, pH, Brix, preservatives, pulp/emulsion content, temperature and packaging conditions. Assess CO₂ quality independently. No PARSWOOD gas-purification equivalent has been established in this guide.

Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Clarified juice and clear cider need a different approach from cloudy juice or cider with retained yeast. Define which solids belong in the finished drink before specifying filtration. High colloidal loading may require upstream conditioning rather than a tighter cartridge.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
For cider, this map begins with the juice or fermented cider at the relevant treatment stage; fermentation is not implied to follow final treatment. Cloudy products do not automatically follow the clarification branch. Filtration alone does not establish juice safety.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Clarification | Reduce unwanted solids and prepare clear liquid for later stages. | Lenticular depth media after suitable bulk-solids removal. |
| Prefiltration | Protect a selected downstream membrane. | PP or depth media based on filterability and loading. |
| Final treatment | Meet the product’s specific stability and safety requirements. | Membrane selection requires organism-specific evidence; do not infer spore control from micron rating alone. |
Review pectin/colloid loading, turbidity, Brix, pH, fermentation status, desired cloud and preservation process. Confirm that trials retain the desired flavour and appearance.

Juice and cider clarification review: use the printable process worksheet. Product links above provide current published specifications. Before selecting a final configuration, request the grade-specific datasheet, food-contact declaration, compatibility information and relevant retention / integrity-test documentation.
Build around the ingredient rather than a single food-industry filtration recipe. Syrups, oils and extracts differ in viscosity, temperature sensitivity and useful components. Depth filtration can clarify selected liquids; adsorption is reserved for a defined treatment objective.
Teal top border: filtration stage · Gold top border: verification or process decision. Maps show treatment logic, not piping or installation drawings.
This is a liquid-ingredient clarification route, not a complete food-safety process. Dairy fractionation, protein concentration, frying-oil treatment and other specialist duties require separate equipment and application studies.
| Stage | Purpose | PARSWOOD approach to evaluate |
|---|---|---|
| Syrups | Manage particles and filterability at actual Brix and temperature. | Depth or PP candidates; evaluate throughput on the actual viscosity. |
| Edible oils | Remove residual suspended material after upstream separation. | Lenticular media may be evaluated for polishing; verify temperature and sensory impact. |
| Extracts and optional adsorption | Target defined unwanted colour or odour. | Carbon candidate media only after trials; allow for a downstream fines-control stage. |
Provide viscosity at operating temperature, solids concentration, batch size and required product recovery. Confirm food-contact documentation for the exact construction and assess cleaning compatibility.
