HIGH PRESSURE SHOWERS PROJECT – SUSTANA/ROLLAND PLANT IN ST-JEROME QUÉBEC.

Application

The high-pressure shower project aims to put high-pressure showers into operation to allow optimal conditioning of covering elements on the paper machine.

Solution

Sizing of new DUPLEX filters allowing 100 micron filtration of the water in the 3 new showers on the wet end of the paper machine

GAIN OBTAINED: No more shower nozzles plugging since the installation was made.

CUSTOMER: SIGMA FACTORY IN Eldorado Gold Quebec. (Mine)

Application:

Filtration of water supplying for 2 “Knelson” concentrators. The original (OEM) equipment filters are very small and difficult to maintain. These had to be cleaned every day and this involves frequent shotdown of the equipment.

Solution: The addition of a large capacity “THOMPSON” filter covering the 2 pieces of equipment, upstream of the OEM filters, allows for a weekly cleaning only of the Thompson filter thus reducing the cleaning needs of OEM filters as they are now only for safety.

Benefits:
• Reduced cleaning frequency
• Increase in equipment availability
• Quick and easy filter replacement and cleaning
• No pressure drop created by the filter
• Excellent filtration quality and efficiency

CUSTOMER: MAJOR PAPER MILL IN ESTRIE

Application

Automated filtration of warm feed water from the mechanical seals of the pumps and primary pulp screens on both of this paper mill’s paper machines.

Solution

Patented self-cleaning filters with a 50-micron internal screen that filter warm water without any human intervention. Protects all of the pumps’ mechanical seals (cooling water, white water and pulp) and the primary screens at the centre of the paper mill. Flow rate is 250 US gpm @ 115 psig.

Advantages

• Elimination of all bag and cartridge filter housings that cost tens of thousands of dollars in replacement parts.
• Uninterrupted and extremely reliable filtration that can be monitored via the operator control room.
• Very minimal annual maintenance fees and maintenance work.

CUSTOMER: KRUGER WAYAGAMACK

Application

Filtration of the river water that feeds an extremely important air conditioner for the plant’s main computer room.

Solution

A Thompson Strainer model MLS-02 with a 20 mesh lined conical basket was installed to replace two small cast iron y-strainers that were completely ineffective and non-functional.

Advantages

• Reduced maintenance and much more easy to do.
• The air conditioner is more efficient and no longer requires honeycomb cleaning every year.

CUSTOMER: RAYONIER A.M. MATANE

Application

Installation of a pneumatic post-filter, in addition to the one already installed by the dual tower desiccant air dryer manufacturer. This dryer produces fine activated alumina dust that contaminates the biomass furnace instrument components.

Solution

The selection and installation of a 3" npt filter housing which contains a pleated microfibre media cartridge with a large filtration area and an absolute filtration of 3 microns. The flow rate is 1,500 scfm at 110 psig with air featuring a dew point of ‑40°F.

Advantages

• No more alumina dust entering the motorized valves.
• This problem has not caused any unplanned shutdown for this oven since 2014.
• The quality of the chosen delta P indicator has made it possible to monitor the life of the filter element.

CUSTOMER: MAJOR PAPER MILL IN ESTRIE

Application

The capture of atmospheric contaminants (moisture and dust) on a gearbox vent of a large water cooling tower’s main ventilation.

Solution

Installation of a patented Air Sentry Guardian breather, 1” npt connection with a desiccant filter element. The filter element changes colour when saturated with water.

Advantages

• The customer has stopped replacing the gearbox every year ($5,000).
• The oil is no longer changed every year.
• Maintenance workers no longer need to work in this cramped and dangerously elevated location.

CUSTOMER: CASCADES CABANO

Application

The filtration of lake water that supplies a large circuit of expensive and extremely critical mechanical seals on the grinder and pulp digester at this paperboard mill’s new pulp mill.

Solution

The installation of two 3” ANSI flanged filter housings, connected in series to the sealing water supply network of two major mechanical seals (value of $125,000).

Advantages

• Total elimination of any potential production stoppages. This allows the maintenance costs of an unplanned breakage, which can be up to $200,000, to be avoided.
• Replacement filter (consumables) costs are very low.
• Fully meets or surpasses the maximum MES standard required by the OEM.

CUSTOMER: PREMIER TECH HORTICULTURE

Application

Hydraulic oil tank contaminated by a dusty environment. This tank operates cylinders and a small hydraulic motor that were replaced frequently.

Solution

A patented Air Sentry Guardian breather was installed in duplicate on a 1,000-litre hydraulic oil tank, operating pressure was 1,800 psi with 3 pumps.This breathers arrangement allows high air flow rates.

Advantages

• The customer has stopped replacing the hydraulic components, which used to break regularly.
• Oil changes are less frequent (less oxidized oil).
• Breather replacement cartridges last long even in that harsh environment.

CUSTOMER: HYDRO-QUEBEC (BEAUHARNOIS GENERATING STATION)

Application

The addition of a post-filter inverted conical screen on the five automatic sand filters used to supply water to the accessories of this hydroelectric power station’s 32 turbines.

Solution

The installation of patented and custom Thompson strainers at the water outlet of each sand filter to capture the “lost sand.” To increase durability, the strainers were built from 316 ss instead of 304 ss on the catalogued product and we pleased the customer with "Victaulic" connections.

Advantages

• Rapid and effective sand leak detection at the sand filter outlets.
• The total stoppage of sand and silica grains via filtration with a 75-micron screen and limitation of damage to the various equipment.
• Thompson filter’s high solids retention capacity, without a significant loss of load or energy.

CUSTOMER: VEOLIA INDUSTRIAL SERVICES

Application

The filtration of wash water from oil tanks.

Solution

The assembly of four carbon steel multi-bag filter housings, each with a 12-bag capacity. Eight-inch connections with ASME and CRN certification.

Advantages

• The recycling of bunker residue at the bottom of the tanks.

CUSTOMER: GOVERNMENT BUILDING

Application

Custom strainer for pre-filtering drinking water at the building’s water intake. This intake feeds all of the plumbing fixtures such as sinks, toilets, showers, etc.

Solution

Semi-automatic strainer, Victaulic and FDA grade coupling, 316 L construction.

Advantages

• Particles produced by the corrosion of this location’s old aqueduct network are no longer present. Sanitary appliances no longer become stained. This was made possible without producing any filter element waste (bags or cartridges), which was one of the client’s requirement.

CUSTOMER: TAFISA CANADA

Application

A Bousquet air handling unit that did not provide the air quality or airflow required to meet the cleanliness standards specified by the production. The filters constantly tore and/or came out of the filter wall.

Solution

The client completed the metal work required to create a rigid, solid filter wall that provided easy access to the filters. Filtrindustries supplied robust, galvanized metal frames. Then, the client installed our Tri-Dim extended surface filters, which consist of 4-progressive-layer “Tri-cube RFX" units, on a permanent cage.

Advantages

• This unit now delivers 120,000 CFMs instead of 85,000 CFMs. In addition, work on the unit (filter changes and plant shutdowns for cleaning) is now much less frequent and more predictable.

CUSTOMER: CASCADES CABANO (PAPERBOARD MILL)

Application

Source capture of caustic soda dust at a manual unloading station.

Solution

12” ANSI flanged housing, installed at the intake of a 1,000 CFM extraction fan. This filter housing has a 4-micron polyester felt cartridge with a very large filtration area.

Advantages

• Eliminates the need to rent a vacuum truck at $3,000/month, for each unloading
• Simple, economical solution requiring minimal maintenance.
• Clean and safe work environment.

CUSTOMER: CITY OF GRANBY

Application

Collection of particles due to corrosion, in the arena cooling system.

Solution

Multi-bag housing casing with 6 baskets, 6’’ flange connections, made of 304 stainless steel.

Advantages
