YWT engineers membrane systems for water treatment, wastewater recycling, ultrapure water, process purification, concentration and product recovery - from conventional duties to demanding acidic, alkaline and solvent-bearing streams.
MicrofiltrationSuspended matter and microbial barrier
UltrafiltrationColloids, macromolecules and RO protection
NanofiltrationSelective ions, organics and process recovery
Reverse OsmosisDesalination, recycle and high-purity water
MBRBiological treatment with membrane separation
SpecialtyAcid, alkali, solvent and difficult feeds
Design Basis
Engineered around the separation objective
A membrane plant is a hydraulic, chemical and operating system - not simply a membrane element. YWT defines the complete process envelope before fixing membrane type, configuration and recovery.
Permeate quality, retained species, molecular selectivity, product value and downstream process requirements.
Recovery & Concentration
Stage recovery, concentration factor, osmotic pressure, reject management and water or product recovery targets.
Fouling & Scaling
Pretreatment, flux selection, crossflow, antiscalant strategy, biofouling risk and cleanability.
Material Compatibility
Membrane chemistry, seals, housings, piping and cleaning agents matched to pH, solvent and temperature exposure.
Lifecycle Performance
Energy, replacement frequency, CIP demand, automation, operator capability and total cost of ownership.
Technology Spectrum
From particle removal to molecular separation
The treatment train may use one membrane step or several barriers in sequence. Final selection is based on testing, data and the intended duty.
MF
Microfiltration
Clarification and removal of suspended solids, fine particles and microorganisms.
Typical role: pretreatment, process clarification and microbial barrier.UF
Ultrafiltration
Robust removal of colloids, macromolecules and turbidity with consistent filtrate quality.
Typical role: RO pretreatment, recycle, depyrogenation and product clarification.NF
Nanofiltration
Selective separation between dissolved species, including hardness, sulphate, colour and targeted molecules.
Typical role: softening, acid purification and selective process recovery.RO
Reverse Osmosis
High-rejection desalination for process water, wastewater recovery, concentration and high-purity systems.
Typical role: reuse, desalination, high recovery and double-pass polishing.MBR
Membrane Bioreactor
Biological treatment combined with membrane solids separation for compact plants and reliable reuse quality.
Typical role: industrial wastewater and sewage treatment with a small footprint.SPECIALTY
Application-Specific Membranes
Membranes selected for acidic, alkaline, solvent-bearing, high-temperature or product-sensitive duties.
Subject to feed-specific compatibility, piloting and performance validation.
Specialty Process Membranes
Recovery and concentration beyond conventional water treatment
YWT's membrane business includes chemically resistant and product-sensitive separations. These systems are developed around the valuable product, the impurity to be removed and the allowable operating and cleaning envelope.
ACID DUTIES
Acid-Stable Membranes
Selective purification, concentration and recovery from acidic process streams where conventional membrane materials may not remain stable.
Applications: acid recovery, impurity removal, metal and mineral process streams.ALKALI DUTIES
Alkali-Stable Membranes
Membrane separation for high-pH streams, caustic recovery and concentration duties requiring alkaline chemical resistance.
Applications: caustic purification, alkaline wash recovery and process reuse.SOLVENT DUTIES
Solvent-Stable Membranes
Organic-solvent nanofiltration and related separations for solvent recovery, product concentration and removal of lower-molecular-weight impurities.
Applications: solvent recycle, API and fine-chemical concentration, product purification.PRODUCT STREAMS
Milk, Juice & Dyes
Product-sensitive MF, UF, NF or RO systems for clarification, fractionation, concentration, colour management and water removal.
Applications: dairy, beverages, natural products, dyestuffs and specialty chemicals.
Dr. Shivenrao holds a doctorate in membranes. His specialist knowledge in membrane science, filtration and separation supports YWT's work across water purification, ultrapure water, chemically resistant membranes, product concentration and recovery.
Flexible delivery within the YWT ecosystem
YWT IndiaMeliorate EngineersEverest Engineering
Depending on the technology, fabrication route, customer requirement and commercial scope, a membrane project may be supplied through YWT India, Meliorate Engineers or Everest Engineering. The proposal and purchase order will identify the contracting entity, scope boundaries and performance responsibility for each project.
Engineering Path
A controlled route from feed to dependable operation
01CharacteriseAnalyse the feed and define variability and risk.
02PretreatProtect membrane surface and control foulants.
03SeparateSelect membrane, flux, pressure and crossflow.
04RecoverOptimise staging, recycle and concentration.
05Monitor & CleanAutomate, trend, verify integrity and restore performance.
Complete Balance-of-Plant
Feed conditioning, cartridge filtration, dosing, pumps, membrane housings, energy management, CIP, flushing, instrumentation, controls and reject handling.
Validation Before Scale-Up
Laboratory screening, membrane coupons, pilot trials and staged performance confirmation where the feed is variable, valuable or chemically aggressive.
UPW & Critical Manufacturing
Membrane systems as the backbone of ultrapure water
For semiconductor, solar, electronics and pharmaceutical facilities, membranes are integrated with pretreatment, ion exchange or EDI, degassing, final polishing, storage and distribution. The design must protect every downstream barrier and maintain water quality at the point of use.
Conductivity / Resistivity
TOC Control
Silica & Boron
Particle Control
Microbial Control
Loop Integrity
Critical principle: UPW is not only a generation skid. Pretreatment, polishing, storage, distribution, materials, sanitisation and monitoring must be engineered as one system.
Applications

Raw & Process WaterClarification, softening, desalination and fit-for-process water.
Wastewater RecycleUF/RO polishing, recovery improvement and reuse-quality production.
ZLD PretreatmentMembrane concentration and controlled feed to MEE, MVR or crystallisation.
