Pall SCHUMACHER Offers Intelli-gent Solutions for Water andWaste Water Treatment

Fine Bubble Aeration for Bio-logical Sewage Treatment

As the value and therefore the cost ofwater increases, and as environmentalregulations for wastewater dischargebecome more stringent, more and moremunicipal and industrial customers decideto treat their waste water as efficiently andas economical as possible.

To meet these strict requirements, PallSchumacher utilises many decades ofextensive application know how, and anenormous reference based range of experi-ence to offer the following HIGHLIGHTS:

Pall Schumacher has a well defined mis-sion: To use its many years of experienceand know how to realize integrated andoptimised solutions to the benefit of itscustomers and the environment. As a resultof many decades in the field of bio-logical sewage treatment plants, PallSchumacher is best positioned to create theoptimum solution and to deal with thewidest variety of applications.

Based on the operating results from morethan 1,000 reference plants, PallSchumacher has fine tuned and optimiseddiffuser geometry to offer a proven design,guaranteed to give successful operation fornitrification, denitrification and organicdestruction (including BOD/COD reduction).

Pall Schumacher has manufactured spe-

cialised porous media used for aerationsince delivery of the first diffuser elements in1918. Over many decades PallSchumacher has developed an optimisedcylindrical diffuser - in close operation withUniversities and Institutes to fulfill alldemands for advanced biological wastewater treatment for today - and tomorrow.For generating the optimum ambient condi-tions for biological action, and to ensure aconstant and safe operation, PallSchumacher offers an excellently uniformdistribution of fine air bubbles using cylindri-cal diffusers in flat bottom aeration techni-que in continuously operated sewage treat-ment tanks.

Experience Based Philosophy.

Optimized pore sizedistribution offers fle-xible air flux ratios.

Pall Schumacher hasa very wide range of

experience, both in the supply of largecentralised municipal sewage treatmentplant, eg. the installation of 35,000 m

BRANDOL® - diffusers in a large centrali-sed municipal plant as well as the installa-tion of a number of smaller 100 m in de-centralised plants.

Customers having chosen BRANDOL®

for their sewage aeration, made the deci-sion based on its excellent functionality, aswell as the very rigid and wear resistantnature of the porous ceramic diffusers:Enduring, continuous and efficient opera-

tion are the significant features, ensu-ring long-evity in service.Our customers often enjoy> 15 years of efficient andtrouble free operationusing our BRANDOL® dif-fusers.This proven service historymeans minimum spare

parts investment and a vast-ly reduced need for changing the

diffusers over the years.

The BRANDOL® ceramic consists of aporous material composed of naturallyspherical quartz particles bonded with asynthetic resin. This porous medium has asmooth inner pore structure and becauseof the chemical properties of the resin,exhibits a natural bacteriostatic activity[against the growth of algae by activatedsludge]. The smooth round structure alsohelps to reduce clogging, giving low pres-sure drops and minimised operating-costs.

A very effective cleaning of the diffuserscan be carried out by high pressure clea-ning if required.

The Process:

The Original:BRANDOL®

The self-cleaning of water, effected bymicro-organisms, is a permanent proce-dure always running in free nature. In eachmountain brook, the water becomes richerin oxygen continuously by its flow, andthus cleans itself.

Repeating natural procedurescontinuously.

The only additive: Clean AirWaste water contains a range of chemi-

cals, organic substances and nitrogencompounds. The objective of the treatmentis to remove these and to discharge theclarified water back into the natural watersor to reuse it after additional UF/RO-treatment. Flat bottom aeration with

BRANDOL® runs continuously withoutinterruption. Ordinary air is injected into thediffuser elements which are installed at adistance of approx. 20 cm from the bottomof the waste water tank generating enoughturbulance to avoid sludge deposition.

BRANDOL® diffusers are available as rigidporous cylinders but also as round porousdiscs. Equally if cylindrical or round, bothBRANDOL® types have a defined pore size toensure specified oxygen flow through thewaste water at a low pressure drop. Theporous texture of BRANDOL® generates milli-ons of fine bubbles enabling high mass trans-fer rates of the oxygen into the waste water

(= oxygen capacity = OC). The individuallyfixed homogeneously distributed diffusers notonly achieve locally high specific transferrates, but also act as mini-mixers whichhomogenise the waste water and establishhigh turbulent flow and local vortexationachieving an excellent cleaning effect by esta-blishing an optimum environment for microor-ganisms.

SCHUMASOIL®- is a porous High Mole-cular Weight Polyethylene well screendesigned to minimise flow resistance. Thisis achieved by providing an optimisedporosity up to 45 % which is uniformly dis-tributed along the well screen's entirelength. Maximised porosity, uniform poredistribution and a tightly controlled poresize, provide the user with the ability to

match flow characteristics of the wellscreen to that of the formation.Conventional slotted well screen has (atbest), an open surface area of between 5-15%, and is only effective in coarse grai-ned soils. Generally, slotted pipe exhibitsundesirable high entrance and exit veloci-ties, which can result in preferential flowand even cause fracturing within the formation. Premature clogging and break-through is also a well known and undesi-rable feature of using simple slotted pipee.g. in fine and sandy soils.

SCHUMASOIL® well screens exhibit anopen surface area of approx. 35% depen-ding on pore size chosen. Conventional vertical water recovery wellsbut also horizontal wells are excellent andtypical fields for the use of SCHUMASOIL®

The porosity of the material provides allthe advantages of a filter pack, but ismuch easier to install due to its lightweight and flexibility. Today, several hun-dred wells in service are equipped with

SCHUMASOIL® well screens.

When high compres-sive strength is requi-

red, SCHUMASOIL® isavailable as Type VBW which has a built inreinforcement. This reinforcement increa-ses the well screen's resistance tocollapse, making it an ideal product touse in horizontal well installations.

The SCHUMASIV TM is available in poresizes from 0,005 µm up to 2,0 µm.

The new hexagonal channels of SCHUMASIV TM-H mean a larger membranesurface and an improved higher permeatflow.

SCHUMASIV TM and SCHUMASIV TM-Hoffer unique advantages, e.g.

High permeate flowExcellent mechanical strengthLong life timeStrong backflushing capabilityChemically and thermically regenerable

STUTTGARTER MASSE is a microporous

ceramic product formed of crushed grains,

available from 0,4 to 12 mm.
