2 Introduction

2.1 General Information

Description

Both Streamline and Mainstream Filters and Strainers are perfect solutions for continuous processing operations.

Mainstream filters and strainers are suitable for vertical mounting using an optional stand, wall mount brackets, or other external

means. The Streamline filters and strainers are suitable for horizontal or vertical mounting, directly into the pipe work.

Both Streamline and Mainstream filters and strainers can use a twin setup. A twin filter or strainer setup consists of two

complete units mounted onto a single stand. Directional valves at the inlet and outlet ports allow one unit to operate while the

filter media in the other unit is being changed or cleaned.

Both Mainstream and Streamline filters and strainers are available in long or short models, with standard construction of stainless

steel. All Mainstream models have side-entry ports. Streamline models have ports either at both ends (model SM or FM), or with

a side inlet, bottom discharge configuration (model SMS or FMS).

Filter Versus Strainer (Mainstream Example Used)

When used as a filter, the unit contains a basket with a disposable bag that allows you to remove undesirable particles from a

liquid or gas (down to 0.5 microns).

A strainer contains a perforated stainless steel basket, v-shaped wire basket, or wire mesh basket that allows you to remove

larger particles (from 73 microns and higher) from the process stream.

Filter/Strainer Options

Mainstream

SEF Mainstream Filter: allows filtering from 0.5 micron to 800 micron using a filter bag.

SES Mainstream Strainer: allows medium or fine straining with either a perforated metal basket (0.033 or 0.062 diameter

perforations) or a wire mesh basket with 20, 40, 60, 80, 100, 150, or 200 mesh. Suited for straining particles

down to 73 micron.

SEB Mainstream Strainer Basket: allows course straining of large particles and foreign matter using large perforations

(0.5, 0.25, 0.125, and 0.09375 diameter).

SEBHVW Mainstream Strainer Basket: allows for fine straining using a v-shaped (Vee-Wire®) basket with wire gaps of 0.005,

0.0075, 0.010, 0.015, 0.020, 0.025, 0.030, and 0.035.

Note: Minimum rating per 3A standard for Vee-Wire applications is 125 microns (0.005 gap.) Vee-Wire is a

registered trademark of U.S. Filter.

Note: 3A does not approve the use of wire mesh baskets or over screens.

Streamline

SM/FM Streamline in-line filter or strainer: allows you to strain or filter using either an overscreen or a filter sock. Suited for

coarse to medium straining ¼" to 200 mesh, or filtering 765 to 40 micron.

SMS/FMS Streamline in-line filter or strainer: allows you to strain or filter using either an overscreen or a filter sock. Suited for

coarse to medium straining ¼" to 200 mesh, or filtering 765 to 40 micron.

3 Installation

3.1 Unpacking

The Streamline filter/strainer comes completely assembled, and ready to install. The Mainstream filter/strainer must be

assembled.

When you unpack the Mainstream filter or strainer, remove the special packing inside the unit. For both the Mainstream and

Streamline units, check for damage that could have occurred during shipping. Report any damage to the carrier.

3.2 Pipeline Installation

Mainstream

Unless otherwise specified, all Mainstream units operate in

a vertical position. Flow translates from the side inlet to the

discharge on the bottom.

Mainstream

Streamline

All Streamline models can operate in any position. Flow for

the standard Streamline versions translates from the inlet

assembly to the discharge on the body. Flow for the side inlet

unit translates from the inlet on the side of the body to the

discharge at the bottom of the body.

3 Installation

3.3 Assembling the Mainstream Stand

1. Remove the triangular base (A) and three right angle adjustable brackets (B) from the packing.

2. Assemble one bracket bolt combination (B) into each of the three slotted base holes with the washer on the underside of the

base and the flat face of the rubber cushion toward the base center. Adjust the three brackets* to the widest opening for the

housing, and partially tighten nuts but do not secure nuts until the housing is placed in stand.

*Note: Slotted holes allow for adjustment so that housing top surface can be level when assembly is placed on uneven floor.

3. Attach the three legs (D) to the triangular base (A) with the plastic or rubber caps upright and notched leg surface to the

outside. Partially tighten the legs, but do not secure bolts (E) until the housing is placed in the stand.

4. Take the retainer ring (F) and orient the three tab slot openings (G) with the three slots so that the tabs (longer tab slot is

down) are located between the notches and plastic/rubber cushion. This will allow the three legs to be opened greater than

the diameter of the housing. The leg notches provide friction to hold legs securely against the housing during process

operations. The retainer ring assembly anchors the legs in place.

5. Place stand assembly in a location that Filter/Strainer housing is to be installed.

6. Lower the housing through the stand retaining ring (F), so that the outlet port fits into the stand base hole (H). (Adjustable

brackets should be wide enough so that no interference occurs between the legs and the housing.)

7. Adjust the angle of the brackets (B) to contact housing, and partially secure in place.

8. Press the tops of the 3 legs (D) on the stand inward so that they rest against the housing. Secure the inlet and outlet process

lines to housing. (See Pipeline Installation.)

9. Lock the retaining ring (F) onto the grooves of the legs (D). Gently use a rubber hammer to secure the ring onto the grooves.

10. Tighten the adjustable brackets (B) and leg bolts (E).

4Operation

4.1 Recommended cleaning

Study the instructions carefully and pay special attention to the warnings!

The strainer housing is designed for cleaning in place (CIP). CIP = Cleaning In Place.

NOTE: All internal components of the filter/strainers must be removed for cleaning (COP) = Cleaning Out Of Place.

Warning: Reverse flow or back flushing through either type filter or strainer can result to damage to the internal

components.

Step 1

Always handle lye and acid with great care

Caustic danger!

Always use rubber

gloves!

Always use protective

goggles!

Step 2

Never touch the filter/strainer or the pipelines during cleaning

Danger of burns!

Step 3

Examples of cleaning agents: Use clean water, free from chlorides. NaOH = Caustic Soda. HNO3=Nitricacid.

1. 1% by weight NaOH at 70°C (158°F).

1kg(2.2lb) +100l(26.4gal) =Cleaningagent.

2.2 l (0.6 gal) +100l(26.4gal) =Cleaningagent.

33% NaOH water

2. 0.5% by weight HNO3at 70°C (158°F).

0.7 l (0.2 gal) +100l(26.4gal) =Cleaningagent.

53% HNO3water

1. Avoid excessive concentration

of the cleaning agent

⇒Dose gradually!

2. Adjust the cleaning flow to the

process.

Sterilisation of milk/viscous

liquids

⇒Increase the cleaning flow!

4Operation

Step 4

Always rinse well with clean water after using a cleaning agent.

NOTE

Cleaning agents must be stored/disposed of in accordance with

current regulations/directives.

Always rinse!

Clean water Cleaning agent

4.2 Starting the System

Important: When installing new non-woven (felt) filter media, recirculate the process fluid through the filter. This will capture loose

fibers before they go down stream.

Mainstream

Ensure that the correct port is used for the inlet. (See figure.)

Starting the Filter System

Open the vent valve slightly. Gradually fill the vessel by opening the inlet valve slowly. Close the vent valve when liquid emerges.

Do not exceed a 10 psi differential across the bag.

Starting the Strainer System

Open the vent valve slightly. Gradually fill the vessel by opening the inlet valve slowly. Close the vent valve when liquid emerges.

Streamline

Ensure that you are using the proper inlet. (See figures.)
