INTRODUCTION

A Leader Evaporator Springtech Reverse Osmosis system is designed to significantly improve the producer’s

productivity by generating higher sugar percentage sap. Through use of high pressure, the system removes water

from the sap resulting in a more concentrated sugar solution entering the evaporator. This in turn shortens the boil

time required and resulting in fuel and time savings. The Leader Evaporator MicRO is ideally suited for the small

producer seeking to gain the advantage of a large reverse osmosis system at an economical cost.

Some of the features of the Springtech MicRO are:

Easy accessibility to pumps and membranes

Stainless steel frame, membrane housings, pumps and pump housings

Flow meter for the permeate of the membrane and for the system concentrate

THEORY OF OPERATION

In reverse osmosis, through the use of special semi-permeable membranes and high pressure, water is forced, in a

pure form, through the membrane while the concentrated solution remains outside the membrane and is

concentrated. For the sugar maker this means water (permeate) is removed from the sap and a sap with a higher

sugar level (concentrate) is produced for the evaporation process.

Terms

Semi-permeable Membrane –Unit consisting of multi layers of spacers and membranes

Pre-Filter Unit –Designed to remove suspended solids from the sap incoming to the reverse osmosis

system

Feed Pump –The initial pump designed to supply the reverse osmosis unit with sap and maintain pressure

in the system

Pressure Pump –The pump designed to provide the pressure needed to force the sap through the reverse

osmosis membrane

Pressure Vessel –The containment unit for the semi-permeable membrane

Permeate –the water removed from the maple sap during the concentrate cycle

Concentrate –the maple sap having a higher percentage of sugar because water (permeate) has

been removed

Permeate Holding Tank –A tank designed to hold a minimum twice the hourly output of the system

Concentrate Cycle –Process during which water is removed from maple sap resulting in

Concentrate and Permeate

De-Sugaring Cycle - Process to reclaim sugars from the membrane during which Permeate is run

through the reverse osmosis unit using Concentrate cycle valve settings

Rinse Cycle –Cleaning process of passing stored Permeate through the Reverse Osmosis system and

out to drain

Chemical Wash Cycle –Process of chemical washing the membranes by recirculating a solution

through the reverse osmosis system. Dependent on requirement, chemical

maybe be alkali or acid.

Permeability Test –Test to determine the performance of the membranes against a benchmark

Sap Recirculation Loop –Process of recirculating output from the concentrate cycle to the raw sap

tank, increasing the concentration of the sap in the tank. NOTE: This loop

is not recommended for this system.

Description of Membrane

The drawing above represents the flow of liquid through a membrane in the system. The membrane is housed

in a pressure vessel (not shown).

EQUIPMENT DESCRIPTION

The LEADER EVAPORATOR Springtech Reverse Osmosis System is designed to offer maximum concentration to cost

performance. Through optimizing of pumps and membranes the reverse osmosis systems deliver greater flow

potential to the user. The LEADER EVAPORATOR Springtech Reverse Osmosis system is designed and built using the

same principles of superior quality applied to our evaporators.

The LEADER EVAPORATOR Springtech MicRO Reverse Osmosis System is covered by a manufacturer’s warranty – See

ATTACHMENT #3.

NOTES:

1. Pictures, sketches and drawings presented in this document are not to scale.

2. Directions (right and left) will be as facing the front of the system except where facing such parts as valves.

3. The pictures in this section are of a system with two membranes. A system with a single membrane is offered.

Rear View

Feed Pump

Provides liquid to the system and

is the first stage of pressurizing

the system

Leader Evaporator Springtech MicRO Reverse Osmosis System Manual YEAR: 2017 Page: 8

Pressure Pump

Second stage of pressurizing the

system required to process the

sap through the membranes

Prefilter Assembly

Prefilter assembly removes contaminants prior to

sap entering the membranes.

Prefilter assembly requires one 10” cartridge filter

Sap is pumped from the feed pump through the

prefilter then to the pressure pump.

Front Panel

The Pressure Switch activates or deactivates the functioning

of the low pressure shutoff control of the system.

The Concentrate Flow Meter indicates the liquid flow, in

gallons per minute, from the concentrate side of the

pressure vessel(s).

The Permeate Flow Meter indicates the permeate flow, in

gallons per minute, from the membrane(s).
