E² Hydrolysis
A knowledge-led, enzyme-assisted approach for selectively transforming suitable sugars, antibiotics and long-chain organic molecules before they burden the common wastewater-treatment system.
Discuss Your Process StreamView YWT InnovationsOperating PrincipleUse a biological catalyst to lower the activation barrier for a targeted hydrolysis reaction.
Under controlled conditions, a selected enzyme interacts with its compatible substrate and accelerates bond cleavage. The products may then be more amenable to downstream treatment, subject to validation.
Complex substrate + H2O → smaller products
SelectiveDesigned around substrate–enzyme compatibility
Source-LevelApplied before uncontrolled stream mixing
ControlledpH, temperature, oxygen and residence time matter
ValidatedBench or pilot evidence defines the operating window
What It Is
E² Hydrolysis is YWT’s in-house process concept for specific decomposition of selected organic compounds through enzyme-assisted hydrolysis.
Enzymes are proteins that act as biological catalysts. They can increase the rate of a compatible reaction by lowering its activation energy and are generally more substrate-specific than many conventional catalysts.
The process is not a generic substitute for an ETP. It is evaluated as a targeted pretreatment or deactivation step for a segregated process stream. Its purpose is to change the selected molecule before the stream reaches downstream biological, physicochemical, membrane or recovery treatment.
Candidate applications can include suitable sugar-rich streams, selected antibiotic-bearing streams and other long-chain organic molecules. Actual conversion, deactivation and downstream benefit must be demonstrated for the specific compound and matrix.
How Enzymolysis Works
Specific recognition, catalysis and bond cleavage
The simplified sucrose example explains the mechanism without representing the design basis for every industrial stream. The enzyme binds a compatible substrate, stabilises the reaction pathway and helps water cleave a susceptible bond.
01 — Substrate binds at the active site
Shape and chemistry determine compatibility.
H2O + CATALYSIS→LOWER ACTIVATION ENERGY
02 — Hydrolysis releases smaller products
The catalyst can participate again within its stable operating window.
Sucrose illustration: sucrose + water → glucose + fructose. Industrial compounds require compound-specific enzyme selection, compatibility testing and analytical confirmation.
Plant-Level Treatment Concept
A clear, segregated and controlled process route
The final arrangement is developed from the compound, concentration, batch profile, wastewater matrix, safety requirements and required downstream outcome.
01Segregate at SourceKeep the identified process stream separate from general effluent so its load and chemistry remain controllable.
02CharacteriseConfirm compound identity, concentration, pH, temperature, inhibitors, salts, solvents and variability.
03Condition the FeedAdjust the environment required for catalytic activity and protect against incompatible operating conditions.
04Enzyme ContactIntroduce the selected enzyme with controlled mixing, aeration where required and defined contact time.
05Reaction HoldMaintain the validated pH, temperature, oxygen and residence-time window while the reaction proceeds.
06Verify ConversionUse relevant analytical markers to confirm the required hydrolysis or deactivation endpoint.
07Transfer SafelyNeutralise or condition where required before releasing the treated stream to its designated next stage.
08Downstream TreatmentIntegrate with the appropriate ETP, biological, polishing, membrane, recovery or disposal route.
Recommended control philosophy: segregated collection → equalisation → conditioning → enzyme reaction → endpoint verification → controlled transfer. Untested streams should not bypass the defined hold-and-release logic.
Potential Application Areas
Where targeted hydrolysis may create value
Application selection begins with the molecule and the treatment objective—not with a generic promise of removal.
Selected Antibiotic Streams
Compound-specific pretreatment or plant-level deactivation before release to the common ETP, subject to analytical proof of the required endpoint.
Requires molecule-specific validationLong-Chain Organics
Selective cleavage of susceptible bonds in compatible long-chain molecules to improve treatability or enable the next process step.
Matrix and enzyme compatibility govern performanceHigh-Strength Side Streams
Source-level intervention for smaller-volume, higher-load streams that can disrupt a common treatment plant when mixed without control.
Segregation preserves treatment leverageBiological Pretreatment
Transformation intended to make a compatible compound more accessible to a subsequent biological treatment stage.
Confirm toxicity and biodegradability after reactionProcess-Specific Deactivation
A controlled reaction step integrated into manufacturing or utilities where the target compound must be changed before transfer.

Application Boundary
Suitability cannot be concluded from the compound name alone. A successful process requires:
- Representative sampling across normal and abnormal batches.
- Analytical markers that distinguish disappearance, transformation and true deactivation.
- Mass balance for parent compound, products, residual enzyme and associated load.
- Bench or pilot trials using the actual matrix whenever practical.
- Defined acceptance criteria before treated liquid is released downstream.
- Site-specific engineering for tanks, aeration, dosing, controls, cleaning and safe operation.
From Concept to Operating System
Evidence defines the scale-up
YWT develops the treatment pathway progressively so that chemistry, engineering and downstream performance are considered together.
01 AnalyseIdentify the target compound and stream matrix.
02 ScreenSelect potential enzyme and reaction conditions.
03 DemonstrateMeasure conversion and downstream effect.
04 EngineerDefine equipment, controls and safe operating limits.
05 OptimiseTrack performance, consumption and lifecycle value.
Technical qualification: Enzymolysis performance is compound- and matrix-specific. Conversion, reaction time, dosage, enzyme stability, deactivation outcome and downstream benefit depend on representative feed conditions and agreed trials. YWT does not present E² Hydrolysis as universally applicable to every sugar, antibiotic or long-chain molecule.
