Working Principle
High filtration efficiency, allows for smaller / less filter tanks.

• Gentle Mixing: random fibers create micro turbulence and a 3-D flow.
• Longer Contact: a turbulent flow results in longer and intensive contact.
• Interstitial spaces enhance build-up of the biofilm.

Choice of types and densities of Matala are function of your influent water characteristics and target effluent quality. Progressive depth filtration increases the sludge holding capacity and anticipates clogging.

Matala Progressive in Mechanical Filtration :


The pictures attest to the high filtration efficiency achieved with the progressive density Matala filter pads. The filter can hold a huge volume of sludge (10 times of its own weight) without clogging.



Matala^® Progressive in Biological Filtration:

Higher Filtration efficiency allow for smaller / fewer filter tanks.

• Gentle mixing: random fibers create micro turbulence and a 3-D flow.
• Longer contact: a turbulent flow results in longer and more intensive contact.
• Interstitial spaces enhance build-up of the biofilm.

1.Surface area tremendously increased by the way in which the flock is held within the web structure.
2.Longer retention of air bubbles in between the web structure fibers.

Submersible fixed Bed Aerobic chamber : BOD loading rate : 1.0Kg/M3/D (filling rate : 60%) BOD loading rate : 0.5kg/m3/Day (filling rate : 47%) or BOD loading rate : 5g/m2/day

Available in different shapes (Sheets, Rolls, and Tubes) to fit your existing tanks or space.



Application of Matala^® in aerobic wastewater treatment
Adding Matala^® in a proper volume ratio to the aerobic chamber will help:

• to stabilize biofilm.
• to reduce the final amount of sludge.
• to build the systems tolerance when influent characteristics and flow rates changes.
• to reach stable effluent quality.

Aerobic Chamber BOD load: 1.0 kg/m3/D. V(media)/V(tank) ratio: 60%. (picture: growing biofilm.)

On-Site small aerated wastewater treatment system. BOD load: 0.5 kg/m3/D. V(media) / V(tank) ratio: 47%. Submersed Filter Bed in Aeration Chamber. Effluent: BOD < 6mg/l, COD: 48mg/l, SS: 4mg/l. TN: 2.88mg N/l, Ammonia N: 1.47mg N/l. System installed as standard process with CE certificated by European company.

Influent: BOD 89.2mg/l, COD:435mg/l. Effluent: BOD 51.3mg/l, COD:235mg/l.

Application of Matala^® in sedimentation process.

3-Dimensional fiber distribution, easier to capture the SS in the water. The fibers of the 3-D Matala® filter web attract particles that conglomerate into flock. Vast amounts of sludge can be build-up within the media before clogging occurs. Short intermittent aeration dislocates flocks that can sediment out of the media.

Advantages
1. Easy to Clean:


Use a submersible water pump with a hose of sufficient diameter and pour a good volume of pond water over the Matala^® media.
OR
Pour a full bucket of pond water over specific sections of the Matala^® filter media.
OR
Temporarily remove 2 sheets of Matala^® and shake the remaining sheets up and down in the filter tank; drain the chamber.
OR
Remove the Matala^® media from the tank; dirty water falls off; drain chamber.
Important Notes:
Remove Matala^® media only if strictly necessary; The above picture proves Matala^® releases its dirt quite easily.
It is okay to gently tap the media on the ground to dislodge the dirt.
Overzealous cleaning is not necessary and will lose too much bacteria. Keep it gentle.
Shake the media up and down in the filter tank; drain chamber.

Something to know before you start cleaning your Bio-filters:
Bio-filters are full of live micro-organisms. Filter media are the bearers of this life. Over-zealous cleansing or purifying the filter media will unbalance the filter ecosystem by eliminating or killing this essential life. Disinfecting or drying of washed media only makes sense in cases where the whole pond needs to be disinfected or dried out.

In essence, cleaning a bio-filter should be only done with the intention to:
Eliminate excessive organic waste (fish excrements, excessive food, plant remains) from the first section of the filter (sedimentation chamber, vortex, etc...). Such need to be done more often to avoid putting an extra burden on the real bio-filter.
Rinse out excessive detritus or accumulated bacterial flock from the latter section of the filter to avoid plugging of the filter media, which would create adverse anaerobic conditions.
Improve the living conditions of the nitrifying bacteria and micro-organisms that thrive in the bio-filter.
Please note that when using Matala^® media in a well-designed bio-filter with proper flow rate it will be difficult to see plugging of this media. Excessive detritus or bacterial flock will tend to slug of and settle to the filter bottom. Purging the filter will take away this detritus.
To clean the real bio-filter section: "Use volume – no pressure"

2. Easy to Cut and Fit:

Matala^®filter pads ared rigid and yet still slightly pliable.
It will hold it’s open 3 dimensional internal structure even if purposely crushed.
It is easy to cut. Use a hole saw to cut circles for pipework. Use a jig saw with a fine tooth blade, or 8" long sharp carving knife for free-form shapes. You can also use band saw, with a very fine tooth blade, or turn the blade and use the backside as knife.
Use a masonry blade turned backwards on a circular saw.

3. Four densities allow for steps-wise transition from mechanical to biological filtration:


4.High free volume for smooth, even water flow throughout

5.Light weight.

6.Versatile and durable

7.Made of Thermo-PE or PP compounds; nontoxic to environment.

8.Form-stable



9.Self-supporing
