The Background

For over fifty years fixed reactors, more commonly known as trickling filters, have been widely

recognised the world over as a reliable method for the biological oxidation of organic wastes.

Biological growth on the media surface of trickling filters converts dissolved organic waste material

into byproducts like carbon dioxide, nitrates, nitrites, water and biological solids which are later

removed by clarification.

Older effluent treatment plants mainly used rock as the surface to induce such biological attached

growth, but this system came with its disadvantages like heavy weight, elaborate supportings and

civil structure, poor wetting characteristics etc. To increase the efficiency of this process, while

retaining the inherent advantages of attached growth system, various technical improvements such

as solids contact, rotary distributor speed control, ventilation and the utilisation of plastic media havebeen made .

..

Performance evaluation at treatment facilities show that at today's high cost of energy, the highly

efficient plastic media trickling filter is the most viable solution to a multitude of wastewater problems.

Many of the serval thousands municipal rock tricking filter plants in use today can greatly benefit by

substituting plastic media. Alternati~ely, these plants could add modern trickling filters containingplastic media, in series or in parallel, to existing systems.

Compared with other wastewater treatment processes, the advantages of the trickling filter, utilising

high efficiency plastic media, are numerous:

• Low Initial Capital costs

• Needs only half the land area of activated sludge basins and only quarter the land area of anoxidation ditch.

• Uses inexpensive, self supporting, light weight modules that are easy to support, contain andinstall for construction.

• Eliminates purchase of expensive, heavy duty aeration pumps.

• Replacement costs are nil since plastic media lasts at least 20 years .

• Low Operating costs

• Operating and maintenance costs are 35-40% lower than activated sludge systems.

• Operational procedures are simple, requiring minimum basic skills.

• Maintenance problems are practically non-existent.

• Sludge generation, treatment and handing costs are considerably less than activated sludge

systems .

•

Requires a much smaller secondary setting tank due to higher setting rate of the sludgeproduced. This is also due to reduced sludge bulking problems .

•• Low Energy Costs/consumption

Overall energy requirements are a quarter of conventional ASP and a sixth of ExtendedAeration plants.

The Rotary distributor is self-propelled, or if motor driven, requires only 1/4 HP/unit.

•• Reliable performance

Consistent BOD reduction as well as nitrification, both in summer and winter operations .

•• High resistance to hydraulic and organic shock loads

Thus low costs, low land requirements, low energyrequirements and simple, dependable operations makeplastic media trickling filters the most cost-effective

method for biochemical oxygen demand (BOD) reduction

nitrification, denitrification, odour scrubbing and

anaerobic treatment. In fact, it was t~e recognition of theefficacy of plastic media that shot trickling filters back tothe limelight as the simplest and most cost-effective

method of effluent treatment, the applicationnotwithstanding.

In the clutter or various

synthetic media that have

been developed ,for

trickling filters, one uniquePVC structured media

has stood out in its ability

to provide trickling filters

with cost effective,

dependable and

controlled performances,

This is SIOdek a modular,cross-fluted PVC

structured media that has

been developed by MM

Aqua Technoldgies Ltdwith technical assistance

from Munters Euroform,

Germany.

Performance Advantages

SIOdek's crossflow design offers performance advantages not found in other synthetic media:

II Its life span is 20 years and the media is UV stabilised.

II SIOdek has proven highly efficient even at depths below 1.8 meters. SIOdek is often used as adirect replacement for rock media for increasing both the degree of treatment and capacity of

existing trickling filters.

II SIOdek's uniform and continuous crossflow provides superior air and water distribution

throughout the media, eliminating the need for forced air ventilation even in large diametertrickling filters.

I! It has a large specific surface area, up to 240 square meters per cubic meters of media.

I! It has a very large voidage - more than 97%.

II SIOdek greatly increases the contact time of the wastewater within the media, resulting in highefficiency with minimum recirculation.

• It has a low, dry weight of 30 kg per cubic meter. leading to a simple and therefore cheapersupporting structure. -

• The distribution pattern (600 cross fluted) provides utilisation ofthe complete surface area.

• Large depths, 6 metes or above, even without intermediate supports, allow considerable savingof land and also increased retention time. This, combined with efficient geometry, can offer a

very compact plant.

• Due to the cross flow configuration, the liquid has about 4 times higher retention time.

• It has a very low resistance to air flow, leading to maximum contact of air, wastewater and bio­mass.

• Low resistance to air flow and the mixing caused at the cross over points in the fill lead to

optimum aeration.

• Excellent wetting and thinner biological growths lead to zero fly nuisance.

• Due to continuous redistribution of water flow the media has a very high resistance to plugging.

I! Setting effluent Total Suspended Solids (TSS) is much lower.

• No elaborate peripheral walls are required because modules are self supporting. Only claddingsuffices.

• Shallow media depths and minimum recirculation rates reduce pumping costs and make SIOdekthe most cost-effective media available.

• Sladek has proven effective in removing SOD at hydraulic wetting rates below 0.6 m3/m2/hr toover7m3/m2/hr.

Aeration by natural draught

Apart from increasing organic and hydraulic loading rates. the use of SIOdek increases the BOD

removal levels to over 90% SIOdek models such as FS 10.19 and FS 10.27 offer very low resistance

to air and provide maximum contact of air, wastewater and bio-mass. SIOdek also provides

thousands of crossover points per cubic meter, thus leading to a very good aeration by natural

draught or ventilation. The air requirement is met by ventilation openings in the wall at the bottom of

the biofilter, which are 4-6% of the cross sectional area of the biofilter. Thus, a daily air volume of

more than 100 cubic meters of fill circulates to provide the necessary oxygen to the micro-organisms.

Simple Support System..

Structurally, SIOdek modules are practically self supporting, requiring supports at only 2 points due

to its light weight. Such simple supports, widely spaced, maxi mise the flow of air and water through

the media and the plenum area, with least obstruction.

Longer Retention time

The 60° cross flow characteristics provide about 3 to 4 times more retention time than other media,

since no free fall of liquid can take place inside the media. Due to this configuration, the wastewater is

distributed over the entire surface inside the media, resulting in a thin, liquid film. This leads to

sufficient time being available forthe biological process and high reduction of SOD.

Low construction co,$ts

SIOdek is self supporting, strong and can be cut to fit into any regular shaped bio-tower, With no

lateral thrust or pressure on the peripheral walls, these walls can be simple, lightweight and cheap.

The exterior cladding is usually from easily available AC or plastic sheets.

Distribution system

The system of interconnected channels in the cross-fluted SIOdk media makes it possible to use

either a rotary distributor or a fixed nozzle system to achieve the desired irrigation. The fixed nozzle

system can be adapted to any regular shaped media plan including the circular trickling filters and is

ideally suited for the square or rectangular tanks. The efficiency is independent of the distribution

system at the tip, since the internal redistribution system in the modules starts to operate

immediately on the wastewater hitting the top layer. In over 6000 mixing points per cubic meter, the

liquid film is broken up and remixed. This turbulence is of vital importance for efficient transfer of

oxygen and the dissolved organic matter between the liquid and the bio-mass.

..

BIOdek, with its unique design, is ideal as a direct replacement for rock media in existing trickling

filters. It can then increase the B005 removal levels in existing trickling filters to over 90% as well as

increase the hydraulic and organic capacities. BIOdek can be placed directly on the salvaged clay

tile (Fig.1.1). Modification to the existing trickling filter structure is not necessary. BIOdek's cross­

corrugated pattern provides continuous and uniform horizontal redistribution of air andwater with no

channelization or short circuiting. The result is maximum utilisation of media surface and increasedretention time of the wastewater in the

media, especially at low hydraulic

loadings.

BIOdek is capable of providing a high

degree of biological treatment at

media depths below 1.8 meters and

hydraulic loadings below 0.55

m3/m2/hr. The graph (Fig. 1.2) shows

the improvement in B005 effluent

quality that BIOdek effects, when

directly replacing rock media.

BIOdek biological treatment media has numerous applications inwastewater treatment. The shape

of the media has a significant influence on application and must be considered along with specific

surface area and void ratio. Applications include upgrading existing rock filters, BOD/COD reduction,

complete secondary treatment, tricking filter/solids contact, roughing of pre-treatments, nitrification,

denitrification, odour scrubbers and a~naerobictreatment.

Upgrading existing rock trickling filters

Applications

Winter time operation and ice formation

Fixed film or attached growth processes are more stable in winter. Apart from this, the high void ratio

and unique geometry of a media such as FB10 are key factors in increasing efficiency and

minimising ice formations. Rock and other types of plastic media present large, horizontal surfaces

where the falling liquid can splash back from ice coatings on adjacent surfaces. FB10 provides an

edge effect, cutting through the liquid, thus eliminating the splash condition. It is on record that even

in sub-zero cold spells, no ice formation on the trickling filter surface is observed, even when the

adjoining walls and areas are under a blanket of show.

BOD Reduction in Trickling Filters

PVC film type, cross-fluted fill media is best suited for biotower application. It provides high surface

area along with the right environm~nt for the growth of micro-organisms, thereby enabling thesystem to take high organic as well as hydraulic loadings.

For industrial liquid waste treatment applications BIOdek design parameters reject the traditional

mathematical model approach to the design of a trickling filter for SOD reduction and base

themselves instead on simulated pilot installations, with waste and operational conditions identical tothe full scale installations. A pH value between 6 and 8.5 and a nutrient balance of 100:5:1 between

BOD, nitrogen (freely available ammonia nitrogen) and phosphorous is normally recommended. The

SIOdek model best suited for biotower applications is FB10, because of its 95-97% voidage.Moreover, its low dry weight and self

supporting nature, further simplifies

the reactor design, leading to lower

capital and operating costs of thebiotower.

Here are some specific advantagesof BIOdek fill media in biotowers:

II Cross-fluted, corrugated fill

media provides large specificsurface areas of 100 to 150

m2/m3 enabling higher loading

rates. This helps in reducing thesize of the reactor.

Sladek used in conjunction with primary and

secondary clarification can reduce BODsand

suspended solids to above 90% See Fig.1.4.

The TF/SC process utilises the trickling filter

followed by short term aeration (Fig. 1.5).

The recirculation of sludge to the aerated

contact basin enhances the agglomeration

of fine particles and improves settling

The hydraulic loading across the top of thefixed film reactor for domestic waste can

range between 0.55 to 6.95 m3/m2/hr.

Recirculation is required only when

minimum hydraulic loading must be

maintained. A performance curve for BODs

reduction at various ;Toadings for municipal

wastewater is shown in Fig 1.3.

• The 60° cross-flted distribution

pattern of BIOdek ensurescontinuous distribution and

redistributions of the wastewater.

This helps of the wastewater to

constantly mix with air and also

•.helps in the utilization of the entireavailable surface area .

• The cross-fluted nature of BIOdek helps

in the right amount of sloughing of

biological growth from time to time.~

II Large voidage prevents plugging

or choking, thereby ensuing

better oxygen transfer throughout

the media. This keeps the systemaerobic and free from foul smells

or files.

In the nitrification process (Fig. 1.7), a

BIOdek biological fixed film reactor provides

an effective means of oxidising ammonia

nitrogen to nitrite nitrogen of secondarytreated wastewater.

Nitrate (N03 - N) levels upto 30 mg/I can be

reduced by over 90% by using BIOdek

biological treatment media in a submerged

upflow mode (Fig. 1.9). Media depths usually

range between 1.8 to 3.7 meters with upflow

rates between 2.3 to 3.6 m3/m2/hr (Fig. 1.10).

BIOdek may also be effectively used for

pretreating difficult wastes or reducing the

organic load on subsequent biological

treatment steps. See Fig. 1.6.

Anaerobic Treatment

BIOdek fixed film biological reactors are

an ideal method for anaerobic treatment of

strong industrial wastes, leachates and a

wide variety of high strength wastes (Fig.

1.13).

Objectionable odours in the form of HzS

generated from wastewater treatment

facilities, can be effectively oxidised with a

BIOdek fixed film reactor (Fig. 1.11).

The contaminated air is biologically

oxidised by the bio-mass sustained on the

SIOdek by primary or secondary treatedwastewater. This oxidation occurs as the

secondary treatment wastewater is

applied across the top of the BIOdek,

couQter to the upward flow of the air beingtreated. In this manner, HzS removals to

below 2 ppm can readily be accomplished

(Fig. 1.12).

SAFF or submerged aerobic fixed film. reactors incorporate the advantages of fixed film

technologies and combine with them the fine bubble diffused aeration techniques, to get a highly

With the higher surfac~ area of SIOdek, higher organic rates are enabled, thus reducing the overallsize required of the aeration tank. This leads to a considerable reduction in civil costs.

The system configuration enables better oxygen transfer efficiency with plug flow conditions.

Submerged fixed film growth in SAFF reactors sustains good microbial growth even in adverse

conditions and also handles shock loads very well. Sludge production is low, no sludge recirculation

The system of interconnected channels in the cross fluted FS 10 media makes it possible to use

either a rotary distributor or fixed nozzle, system to achieve the desired irrigation. To ensure

adequate contact time and liquid film diffusion,

SIOdek is capable of redistributing the wastewater

horizontally over a minimum of 30 em per 30 cm of

media depth. SIOdek provides a minimum of 6000

mixing or horizontal redistribution points per cubicmeter of media.

The media is resistant to rot, fungi, bacterial

growth and other forms of micro-organisms

and is chemically resistant to normal concentrations of sewage acids, alkalis, organic solvents,

organic compounds and other water soluble substances occurring in municipal and industrialwastewaters.

SIOdek is designed with a surface area of 102-240

square meters per cubic meter of. media with aminimum of 95% void to volume ratio. The SIOdek

media modules are selected for each installation

bases on load test data obtained in compression

tests. This ensures adequate bearing capacity for

each specified loading requirement. The PVC

compound is UV resistant and specially formulated

to resist long-term fatigue cracking under

continuous loading.

MMA TL's plastic fill media for effl uent treatment

SIOdek fixed film biological treatment media is a self supporting crossflow synthetic media. It is

fabricated from completely corrugated, rigid PVC sheets and forms a cross-corrugated pattern

with each adjacent sheet. Unlike conventional modular sheet media, no flat sheets are used in

the fabrication of the module. Each sheet is corrugated at a 60° angle and assembled in a cross­

corrugated pattern with adjacent sheets.

This configuration provides continuous anduniform horizontal redistribution of both air and

water throughout the full depth of the media.

(Fig 2.1).

The result is greatly increased contact timebetween the wastewater and the media bio­

fUm (Fig 2.2) as well as increased liquid filmdiffusion.

#FB 53.01. To optimize the effectiveness of various applications of the trickling filter process, each

media has been designed with unique product characteristics that meet specific performance

requirements.

Installations of BIOdek have to-date tolled to nearly 50,000 cubic meters. There are over 250

installations all over t~,~world currently in successful operation. These range from small units of fewhundred cubic meters to several hundred thousands cubic meters of media.

MMATL has developed vertical BIOdek FB33 and FB53 Anti-Fouling PVC Fill Media to minimize

clogging for attached growth biological treatment specially in anaerobic systems. FB33 or FB53

sheets can be used alternatively with the well known cross-fluted FB10.27 sheets to from

FB33.27(VX) or FB53.27(VX) and also with plain sheets to from FB33.01 (VP) or FB53.01 (VP).

Installation

The recommended BIOdek support system consists of steel "I" section beams or concrete beams

installed paralle'j at 600mm or 900mm centers. Each full module on the bottom layer is centered

across with the longer sides at right angles to support the beams. The bio-oxidation tower walls are

not subject to any lateral loads and need only be designed for wind loads. A cladding with I"..'.'.plastic/FRP/ AC sheets would normally suffice.,
