‘UnitedMizu Industries Pvt. Ltd.’ (UMI) is a well-established and growing engineering company. Led by the team of professionals, supplying innovative Turnkey Zero Liquid Discharge (ZLD) focused on generating profits from waste by utilizing minimum energy.
UMI are manufacturing following products Caustic Recovery Plants (CRP) Heat Recovery Unit (HRU)
Salt Recovery Plant Multiple Effect Evaporator Plants (MEE), Mechanical VaporRecompressor (MVR),
Agitated Thin Film Dryers (ATFD) Solvent Recovery and Stripper Systems
Caustic Recovery Plant (CRP) for Mercerizing Machine
Mercerization is a finishing process in the textile industry where the textile fibers are treated under tensile stress with caustic soda. Large quantities of diluted caustic soda (weak lye) are a waste product of this process. UMI Caustic Recovery Plants (CRP) can turn a very large proportion of this weak lye into reusable concentrated caustic soda (strong lye).
UMI have developed technology to make get colourless caustic even from process such as Yarn Dyed OR Denim Mercerization.
• Payback-time is less than one year!
• No alkaline waste water from mercerizing machine
• Generation of hot water from the waste energy
• Generation of soft water, the vapor condensate is slightly alkaline
• Recovery of surplus lye for wet-on-wet mercerizing
• No contamination of the heating steam
• Environmental protection: less chemicals for neutralization are needed

Multi Effect Evaporators
Forced Circulation Evaporator used for concentrating high viscosity material and products with higher solids to achieve desired concentration. In this type of evaporator, the liquid is pumped through tube side of Calandria at high velocity avoiding precipitation and fouling the liquid is then passed through vapor separator for separation of vapor. Concentrated liquid is continuously discharged from bottom of the vapor separator with pump.
- Fouling of tubes is minimized
Designed for highest steam economy
• High recirculation is to be maintained inside the tubes by recirculation pump
• High TDS and viscous liquid concentration
• Rising Film Evaporator
• Low pressure drop
Mechanical VaporRecompressor (MVR)
MVR (Mechanical Vapor Recompression) technology can reduce the energy consumption of the evaporation system significantly. The pressure, temperature and enthalpy of the secondary steam generated by evaporation increases after compressed by the steam compressor, then the steam enters the heating room as heat resource, so as to continuously circulate. This type of evaporation system consumes electrical energy for evaporation operations. Energy consumption of compression fan varies slightly, depending on different material properties.
UMI have made portable Pilot Plant to conduct trails at client
Heat Recovery System
WITH THE INCREASING COST OF ENERGY, IT IS IMPERATIVE TO LOOK AT ALTERNATIVES TO SAVE ENERGY. AS ENERGY IS MONEY, ANY SAVINGS IN ENERGY DIRECTLY LEADS TO SUSTAINABLE OPERATIONS. ENVIRONMENTAL IMPACT ALSO NEEDS TO BE CONSIDERED TO REDUCE THE ISSUE OF GLOBAL WARMING.
IN CONSIDERATION OF THE DIRE NEED OF THE INDUSTRY TO CONSERVE AND REDUCE WASTAGE OF ENERGY, WE ARE PROUD TO INTRODUCE OUR AIR-TO-AIR HEAT RECOVERY UNITS FOR STENTERS AND DRYERS.
IN ANY PROCESS HOUSE HOT AIR STENTER AND DRYERS ARE THE MOST ENERGY CONSUMING SYSTEM.
APART FROM THE THERMAL ENERGY REQUIRED FOR EVAPORATION OF WATER DURING DRYING AND FINISHING, CONSIDERABLE AMOUNT OF ENERGY IS LOST IN THE EXHAUST.
THIS SITUATION LEADS TO VARIOUS ISSUES. WHILE MAJOR ISSUE IS THE LOST OF COSTLY THERMAL ENERGY, IT ALSO LEADS TO THE HEATING UP OF ATMOSPHERE, THUS ADDING TO THE GLOBAL WARMING PROBLEM WHICH IS GETTING OUT OF HAND AND WHICH NEEDS TO BE HANDLED ON WAR-FOOTING.
WE HAVE DEVELOPED HEAT RECOVERY SYSTEM WHICH RECOVERS PART OF THE ENERGY IN THE HOT AIR IN THE EXHAUST DUCTING BEFORE IT IS LET OFF TO ATMOSPHERE. SIGNIFICANT AMOUNT OF THEMAL ENERGY IS RECOVERED BY PRE-HEATING THE FRESH AIR. THIS PRE-HEATED FRESH AIR IS FED INSIDE THE STENTER AND DRYER CHAMBERS. THE EXHAUST AIR IS PARTIALLY COOLED WHICH HELPS CONSIDERABLY IN REDUCING THE GLOBAL WARMING PROBLEM.
IN A TYPICAL HEAT-SETTING OPERATION, THE FRESH AIR AT AN AMBIENT TEMPERATURE OF 38 DEG C GETS PREHEATED TO ABOUT 80-90 DEG C WITH THE HELP OF OUR HEAT RECOVERY SYSTEM. THE PRE-HEATED AIR AT HIGHER TEMPERATURE ENTERS IN THE CHAMBER THEREBY REDUCING THERMAL ENERGY CONSUMPTION CONSIDERABLY.
SUSTAINABILITY IS ACHIEVED BY MAINTAINING CONSISTENCY IN OPERATIONS. PERFORMANCE IS MONITORED WITH THE HELP OF PLC PROVIDED WITH THE SYSTEM.
EASE OF OPERATION AND MAINTENENACE IS ENSURED BY HASSLE-FREE REMOVAL AND CLEANING OF FILTER SCREENS. QUICK RESETTING THE STENTER FOR PRODUCTION IS POSSIBLE DUE TO ON-SITE CLEANING OF THE HEAT RECOVERY UNIT.
