Reverse Osmosis Plant (Spiral Wound Membranes)

Highlights and application:

Reverse Osmosis (RO) offer a range of possibilities for concentration and demineralization of different dairy products. The RO SW system is characterized by:

-Whey concentrate up to 18% TS, thereby increasing whey quantity and reducing transport cost

-Low plant investment

-Low space requirements

-Easy membrane change

-Sanitary design

-Reduced environmental impact

-Substantial return of investment

 

The SW membrane is a unique design, where a large membrane area is wound into a compact element. SW elements are available with:

– Various diameters (3.8-8 inches)

-Various lengths (38-40 inches)

-Various feed spacers (20-50 mil)

-Special design for high pH/high temperature CIP

A number of membrane elements are fitted into a stainless steel housing to form a module, and a number of modules are built into a plant.  Based on proven, modular components, each plant is customized to fit the individual applica­tion. Further, the plant design allows for access to maintenance of all vital parts as well as for future cost effective plant modifications. RO plants with SW membrane elements can be supplied with any type of process auto­mation ranging from a simple, manual to a fully automatic system, integrated in the overall fac­tory control system.

 

Typical applications of RO system are as follows:

– Concentration of milk, whey and UF permeate

– Recovery of product residues and pure water from mixed product/water streams

Capacities:

Standard RO Plants with fixed capacities which are manufactured by this company are as follows:

-Milk Concentration: 5000-30000 Lit/hr

-Whey and UF Permeate Concentration : 5000-30000 Lit/hr

-White Water Recovery: 5000-20000 Lit/hr

Higher capacities are available based upon request and can be tailor made.

Components:

RO Plant usually includes the following components:

-Closed balance tank including level transmitter and  CIP device

– Valve manifold including set of change over valves and automatic butterfly valves

– Feed pressure system including feed pumps, flow transmitter and in line filte

-RO Modules and filters

– Re circulation loops each including circulation pump, tubular heat exchanger, pressure and temperature transmitters, flow indictors and sampling device

-Retentate/Permeate system including modulating valves, flow transmitter, permeate pump

-Equipment for flush water including shut off valves and adjustment valves

-Equipment for steam and cooling water including shut off valves and non-return valves

-Set of pipes and fittings

-Set of shut off valves for water balance tank

-Set of instruments such as temperature and pressure transmitters.

-Stainless steel control panel including PLC, HMI, power supply, solenoid valves, motor starters, MCC etc.

-All of the RO plants  are tested in our factory before delivery

-The RO Plant Panel/Programme ensures the following are realized:

۱-Automatic temperature control in the loops

۲-Automatioctotal solid ration control in the final retentate

۳-Recording feed and retetnate flow and each loop temperature as long as long as the memory of HMI allows it

 

Options:

RO plant can include the following options:

-Automatic CIP dosing unit

-In line cartridge filters for soft water input

-In line filter for product with 10 micron filter

-Mix proof product manifold valve on feed, retentate and permeate inlet/outlet

-Conductivity transmitter for CIP dosing

-Automatic shut off (Isolation) of each loop to cut water consumption during CIP

-Flush water seal re circulation system. Reducing water circulation

-Dia filtration system to enable reaching a higher degree of demineralization

-UPS (Uninterrupted Power Supply)

-Air cooler for Control Panel

 

Operation:

The RO plant is designed fully automatic and from HMI all of the operation parameters and program sequences can be controlled and monitored. Also, all of the necessary process alarms are already incorporated into the program. The operation presence is only required during operation as surveillance The following process sequences are realized automatically:

-Start up/ Recirculation/Ready for product

-Pre concentration

-Production

-Re circulation of product

-Emptying

-Rinse

-Cleaning in place (CIP

 

Utilities:

The required utilities for running the RO plant are as follows:

 

Power supply: ۳×۴۰۰ V AC, 50 Hz (Other voltage and frequencies are also available upon request)
-CIP water supply: ۲-۳ bar(g) @ 10-50 C
-Cooling water supply: ۲-۳ bar(g) @ 10-50 C
