Other Equipment

Your Challenge:
You need to do everything you can to improve the efficiency of your plant. Reduce downtime. Reduce repair costs. Reduce waste. Now you can dramatically reduce the risk of unplanned equipment failure by improving the condition of the lubricants.

Results:
The PurLube is an advanced, simple and effective on-line system that utilizes the principal of air stripping to remove water from your hydraulic oils and industrial lubricants. The Colfax PurLube efficiently outperforms centrifuges, coalescers and the much more complicated vacuum dehydration systems.

Solution:
You get immediate results that go straight to your bottom line. The PurLube eliminates all machinery failure due to poor oil quality. It also eliminates the need for oil changes and expensive and toxic oil waste by always keeping your oil like new. You immediately save money by eliminating the need for new oil purchases and expensive oil inventories. Even your most basic maintenance procedures such as filter changes take place much less frequently. Perhaps most important, the PurLube improves the overall efficiency and reliability of your expensive rotating equipment.

Principle of Operation:
The PurLube works on the principal of air stripping. The use of air bubbled through contaminated liquids has long been used to remove contaminants. But the use of this technique was restricted because the volume of gas required was large due to limited mixing of the air with the liquid. The unique technology embodied by the PurLube makes air stripping practical and efficient because of the mixing and intimate contact of the air with the fluid being cleaned. In addition, the PurLube utilizes the principle that the capacity of air to entrain moisture increases exponentially with temperature. For example, with a 130° Fahrenheit increase in temperature, there is a 30-fold increase in the capacity of air to hold moisture.

Benefits of the PurLube System:

• Improve equipment reliability
• Extend life of rotating equipment
• Fewer forced equipment outages
• Extend fluid life
• Reduce fluid disposal costs and environmental risks

A blower is a machine for moving volumes of a gas with moderate increase of pressure. A vacuum pump is the same where the removal of gas volume leaves behind a partial vacuum.

The low pulsation rate and gentle performance of KAESER positive displacement pump is achieved due to a combination of its two 90deg helical twisted rotors, and a triangular shaped sealing line configuration, both at the point of suction and at the point of discharge.

Mixers, also known as agitators, are used in tanks to help combine various substances into compounds, and/or maintain suspension of solids in a liquid matrix, by providing constant movement so that the solids do not drop to the bottom of the tank and "settle out". In industry, most mixers are either top entering (vertical) or side entering (horizontal), to allow for ease of maintenance. Power requirements can be anywhere from fractional to hundreds of horsepower, depending on tank size, fluid and agitation requirements.

Since being established over 80 years ago John Crane has become the acknowledged global leader in seals. The earliest seal made by John Crane was the mechanical packing material. Still used today, in some situations, packing material is not adequate for sealing a pump shaft. One common alternative method for sealing the shaft is with mechanical seals. The mechanical seal was developed to overcome the disadvantages of compression packing (45-60drops/min leakage). While not leak-proof (5 drops/min), mechanical seal leakage can be reduced to a level meeting the environmental standards of local, state, and federal regulatory agencies; and maintenance costs are lowered ie pump shaft is not worn, power savings. Mechanical seals consist of two basic parts, a rotating element attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.

John Crane offers a comprehensive range of engineered mechanical seals and sealing support systems, mechanical packing, power transmission couplings and asset.

Cerlic has developed the only total suspended solids meter that actually measures suspended solids. Based on the principles of light transmission, the total suspended solids meter measures near infrared light 5 times a second across a specific gap in the detector. The measurement is unaffected by the color of the liquid in the meter and is compensated for temperature and light source strength. The calibration frequency is very infrequent. The meter measures particles 0.88 micron and larger.

A plate heat exchanger is a unit which transfers heat continuously from one media to another media without adding energy to the process. The basic concept of a plate and frame heat exchanger is two liquids flowing on either side of a thin corrugated metal plate so heat may be easily transferred between the two. The plate heat exchanger efficiency requires less floor space compared to other types of heat transfer equipment and is lighter in weight.

Clarifiers and screens are used to remove solids from liquids through gravity settling or mechanical screening processes. Wastewater clarifiers are also used for clarification of bio-solids prior to discharge to the fields. Clarifiers and screens perform primary functions in wastewater treatment systems.

Treatment equipment such as clarifiers and screens, comminutors, and grit chambers are used as wastewater first enters the treatment plant. API (American Petroleum Institute) separators are used in the treatment of refinery wastewater that has been contaminated by oil and oil-bearing sludge. In an API separator, wastewater is collected in a pretreatment section that allows sludge removal, and then further treatment processes are used to more completely remove entrained oil in all forms.

Water clarifiers, similar to clarifiers and screens, assist in optimizing a treating system by improving efficiency and helping to purify produced water to meet effluent water specifications. A water clarifier consists of special blends of polymers, coagulants, surfactants, and metal salts which work in conjunction with process systems to remove oil and water soluble organics (WSOs) from the water. These types of clarifiers and screens reduce the turbidity or cloudiness of the water and remove particulate matter that could plug up down-hole production or disposal formations.

Oil/water separators (OWS) are specialty tanks designed to separate free oil, grease and settleable solids from water. After separation, clean water is discharged to a storm sewer, while the separated oil is retained in the tank for proper disposal at a later time. Oil/water separator applications are generally for rainwater runoff and equipment wash downs.

The Copa Mechanical Raked Bar Screen is suitable for almost all CSO applications. The Mechanical Raked Bar screen's modular design makes it easy to retrofit, through 600mm diameter manholes, into existing overflow chambers.

•  4, 6, 8, 10 and 12 mm bar spacings
• Continuously mechanically raked
• Can retrofit through 600mm diameter manhole
• Stainless steel
• Retains screenings in the flow
• Hydraulic Drive

Applications

The Mechanical Raked Bar Screen applications include storm tank discharges, emergency overflows on pumping stations, storm weirs on sewage treatment works and overflows within the sewage system. The screen is ideal for both retro-fit and new Storm overflow chambers.

Operating Principle

The Copa Mechanical Raked Bar Screen allows water to pass through to overflow whilst retaining the screenings in the flow. The screen is continually raked by a hydraulically driven cleaning mechanism. Flow rates from 50 -2400 l/s can be catered for with a single screen module, although multiple units may be used to increase flow capacity.

With over 250 screen installations ranging from 50 l/s to in excess of 20,000 l/s the Copa Mechanical Raked Bar Screen has a proven track record for efficient, reliable and cost-effective sewer overflow screening.

Operation

Eimco Water Technologies, following extensive testing into vertical CSO screens concluded that they are far less efficient than screens which are installed horizontally. The Copa Mechanical Raked Bar Screen utilizes fixed stainless steel bars which can be retrofitted through a 600mm diameter manhole.

The bars are continually raked by a hydraulically driven cleaning mechanism. Water is allowed to pass through to overflow whilst screenings are retained in the continuation flow.

Research Lays Vertical Screen to Rest

Use of the horizontally configured screens ensures that all flows, whether high or low, are screened with velocities kept to a minimum. The entire flow is in contact with the screen whilst the perpendicular flow path screens more efficiently.

Because the bars of the horizontal screen are actually oriented vertically, they are far stronger than horizontal bars which tend to sag, especially on longer screens and the vertical bars can be walked on for more convenient access to the installation.

Maintenance

The normal maintenance of the Mechanical Raked Bar Screen is to inspect the screen periodically to ensure the surface area of the screen is free from any obstruction. It is also recommended that a dry run test is carried out. Both procedures are easy to carry out.

All maintenance may be carried out from the top/clean water side of the screen with the guide rods, combs, and drive unit being easily removed for replacement/inspection. The main framework and screening bars should not be required to be removed; however should this be necessary, each module may be split from its partners and removed. Should this be a slave unit from the end of the screen assembly, then it is possible to re-establish the operation of the screen without this module at a reduced flow capacity.

Other required maintenance includes replacing the hydraulic fluid within the hydraulic pump which may be carried out at its location within the control kiosk. These oil changes/checks should be carried out on an annual basis.
