Frac Tanks
A frac tank is a large capacity steel tank that can store liquids or solids like petroleum products, chemicals, manure, saline water, and proppants. Frac tanks are used in oil and gas, construction, environmental remediation, municipal, and agriculture.
​
Benefits of Frac Tanks
-
Frac tanks can store large amounts of industrial liquids.
-
Frac tanks can be easily coupled using hoses to other devices such as pumps, filters, and other equipment on site.
-
Some types of frac tanks help maintain the viscosity of liquids, separate liquids and make the filling or draining process easy.
-
There are many frac tank types with smooth walls, corrugated walls, steam coils, rounded bottoms, and more to meet your project needs.
-
Frac tanks are highly mobile and can be transported using a truck or a tractor.
-
Frac tanks come in different sizes ranging from 7,070-gallon mini tanks to 21,000 gallon closed-top tanks.
FRAC TANKS - CLOSED TOP
Closed top frac tanks are temporary liquid storage tanks with flat tops. They are ideal for any project where safe and reliable on-site liquid storage is required. These frac tank sizes range from 8,400 gallons to 21,000 gallons. All our closed top frac tanks offer various interior features like a rounded bottom dual manifold, bare steel interior, heating coils, epoxy coated interiors, smooth walls, and insulation.
​
These tanks come in various sizes ranging from 8,400 gallons to 21,000 gallons and can be easily moved when empty using a tractor or a truck. This structure creates a central low point from which the tank is easily emptied and cleaned. No need to tilt the tank!
​
FRAC TANKS - OPEN TOP
Open top frac tanks are durable quarter inch thick steel tanks with an open top to make it easier to monitor levels of liquid stored inside and for cleaning. These frac tanks store liquids like run-off water and non-hazardous chemicals. Open top frac tanks come in a range of sizes from 7,932 gallons to 21,000 gallons, and include features such as three inch top fill line, sloped ‘V’ bottom for 100 percent drain out, and a fixed rear axle for easier movement.
MIX FRAC TANKS
Our mix tanks are available in either 7,070 gallon or 18,270 gallon steel tanks, free of internal rods or corrugations that constantly agitate and circulate stored liquids. Operators control the mixing rate with four individual 10 HP motors. Mix frac tanks come with safety features such as guardrails, non-slip materials, walking areas, and audible alarms.
OPEN TOP WEIR FRAC TANKS
Open top weir tanks are steel frac tanks that help control the flow of liquids up to 100 gallons per minute (GPM). Their primary function is to segregate residual fluids, oils, and contaminants using weirs or baffles inside the tank. These 18,000-gallon tanks are configured for faster drainage and easier cleaning.
Bag Filtration Units
Bag filtration is a versatile and cost-effective way of filtering high volumes of water with high flow rates. Bag water filters are ideal for industrial applications, brewing, prefiltering, and more. These high-capacity systems can handle 90 – 2,400 gallons of water per minute. They’re great for reducing the amount of silt, sand, dirt and other types of sediment in your water.
​
Bag water filter treatment is when one or more bag filters are placed inside a bag filter housing to remove suspended solids from water. Specific bag filters vary depending on the industry in which they are used. This filtration method is both versatile and cost-effective for filtering lots of water quickly. They’re great for reducing the amount of silt, sand, dirt and other types of sediment in your water.
​
There are a few, significant benefits of bag water filter treatment. These include:
· Filter large volumes of water with high flow rates – easily filter 90 – 2,400 gallons per minute (filter and housing dependent)
· Bag filters have a high dirt-holding capacity – change bag filters far less often than cartridge filters
· Withstand exposure to a wide range of conditions
· Bag filters are easy to install and replace
· One of the most cost-effective ways to treat high volumes of water – cartridge filtration can’t compete on these volumes of water for the price
Bag water filter treatment is ideal for commercial, industrial, and municipal filtration applications that require a cost-effective way to filter large volumes of water at a high flow rate. Such applications include:
· Agriculture
· Pre-filtration
· Brewing
· Removal of coarse particles which could potentially damage your equipment
· Removal of challenging pollutants from a liquid stream
· Groundwater
· Cooling water
· Industrial process water
· Wastewater
​
At LIS we rent bag filters in various configurations and sizes. From single bag units to multi-bag units to complete engineered systems.

Carbon Adsorption Units
Activated carbon is a highly porous substance that attracts and holds organic chemicals inside it. The media is created by first burning a carbonaceous substance without oxygen which makes a carbon “char”. Next, the “char” is treated chemically or physically to develop an interconnected series of “holes” or pores inside the carbon. The great surface area of this internal pore network results in an extremely large surface area that can attract and hold organic chemicals.
​
Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated carbon is produced specifically so as to achieve a very big internal surface (between 500 - 1500 m2/g). This big internal surface makes active carbon ideal for adsorption. Active carbon comes in two variations: Powder Activated Carbon (PAC) and Granular Activated Carbon (GAC). The GAC version is mostly used in water treatment, it can adsorb the following soluble substances:
-
Adsorption of organic such as:
-
Mineral oil & hydrocarbons
-
BTEX
-
Poly aromatic hydrocarbons (PAHs)
-
(Chloride) phenol
-
-
Halogenated substance
-
Odour
Water is pumped in a column which contains active carbon, this water leaves the column through a draining system. The activity of an active carbon column depends on the temperature and the nature of the substances. Water goes through the column constantly, which gives an accumulation of substances in the filter. For that reason the filter needs to be replace periodically.
​
Liquid phase carbon adsorption is a full-scale technology in which water is pumped through one or more vessels containing activated carbon to which dissolved organic contaminants adsorb.
LIS rents and manufacturer’s a variety of adsorption vessels for use with granular activated carbon. LIS can provide individual adsorption units or complete engineered systems containing multiply carbon vessels that operate in series or parallel. Vessels are available in various sizes and materials of construction such as fiberglass or steel. All vessels are pressure rated to a minimum of 75 psi. Higher pressure ratings can be provided upon request.

Sand Filtration Units
Sand filtration works by using multiple layers of specialized sand and gravitational fluid pressure to retain solid particles suspended in liquids, resulting in a cleaner product. As fluids pass slowly though layered sand and gravel beds, natural physical, biological, and chemical processes combine to provide treatment.
​
Sand is a widely available and affordable filtration media capable of removing suspended solids and producing high quality water with improved colour, taste, and odor, as well as removing 90-99% of pathogens.
Sand is used in the following types of filtration systems:
​
-
wastewater treatment (septic or municipal)
-
commercial and industrial applications
-
drinking water purification
-
swimming pool filtration
-
membrane (pre-filtration)
-
grey/surface water filtration
-
aquaculture seawater
Similar to carbon adsorption vessel operation, water is pumped in a column which contains the various sand filtration media. The filtered water then leaves the column through a draining system. The primary difference between carbon adsorption vessels and sand filters is that sand filters normally have a larger diameter due to the requirement for a slower flow. However, depending on the system requirements, it is often possible to use carbon adsorption vessels in sand filtration applications.

LIS rents and manufacturer’s a variety of pressure vessels for use with sand filtration. LIS can provide individual adsorption units or complete engineered systems containing multiple sand filters that operate in series or parallel. Vessels are available in various sizes and materials of construction such as fiberglass or steel. All vessels are pressure rated to a minimum of 75 psi. Higher pressure ratings can be provided upon request.

Oil/Water Separators
Oil/water separators are essential in industries and facilities that deal with large amounts of contaminated water. These separators are designed for removing oil and other pollutants from wastewater before it is discharged into the environment or municipal sewer system. This allows establishments to comply with environmental regulations and prevent oil pollution of water bodies.
​
An oil/water separator is a device that separates oil and water from industrial or commercial wastewater through the use of a coalescent filter and gravity. As liquids pass through the vessel, the oil, water, and solids will begin to separate due to gravity. The oil will rise to the top of the vessel, and the solids will fall to the bottom. This will leave the remaining water in the middle to pass through our coalescent filter. This filter traps any remaining oils that have not yet separated, allowing the filtered water to pass through towards the discharge. The risen oil should then be skimmed from the top every so often.
​
Our separators feature multiple compartments with coalescent filters in between. This maximizes the effectiveness of separation. As well, our locking valve prevents the separator from continuing operation if the oil levels get too high. Based on request, we may also have sensors available to monitor the sediment/oil levels.
Products removed: motor oils, fuels (vehicle/jet), fuel oils, hydraulic fluids, immiscible machining oils, lube oil, transmission fluid, bunker c, DNAPL, LNAPL, vegetable based oils, crude, air compressor lube & other hydrocarbon based derivatives (BTEX etc.). Model sizing is based on the oil/fuel specific gravity, droplet size removal desired and other parameters of the waste stream .
LIS manufacturers and sells a variety of above ground oil water separators to suit virtually any need. Flowrates can range from 5 gpm to 150 gpm or larger upon request.

Ultrafiltration & Nanofiltration
Filtration is a process of removing particulate matter from water by forcing the water through a porous media. This porous media can be natural, in the case of sand, gravel and clay, or it can be a membrane wall made of various materials. Both of these membrane filtration processes are effective methods of treating water that cannot be treated using conventional treatment methods.
​
The size of materials that can be removed during filtration depends upon the size of the pores of the filter. The chart below summarizes the various separation processes relative to common materials that would be filtered out through each process. Particle filtration refers to conventional media filtration, while the other types are membrane filtrations.
​
WHAT IS ULTRAFILTRATION?
An ultrafiltration filter has a pore size around 0.01 micron. A microfiltration filter has a pore size around 0.1 micron, so when water undergoes microfiltration, many microorganisms are removed, but viruses remain in the water. Ultrafiltration would remove these larger particles, and may remove some viruses. Neither microfiltration nor ultrafiltration can remove dissolved substances unless they are first adsorbed (with activated carbon) or coagulated (with alum or iron salts).
​
WHAT IS NANOFILTRATION?
A nanofiltration filter has a pore size around 0.001 micron. Nanofiltration removes most organic molecules, nearly all viruses, most of the natural organic matter and a range of salts. Nanofiltration removes divalent ions, which make water hard, so nanofiltration is often used to soften hard water.
​
WHAT DO THESE PROCESSES REMOVE?
Ultrafiltration removes bacteria, protozoa and some viruses from the water. Nanofiltration removes these microbes, as well as most natural organic matter and some natural minerals, especially divalent ions which cause hard water. Nanofiltration, however, does not remove dissolved compounds.
​
Visually ultra and nanofiltration units appear almost identical. The main difference is associated with the size/type of filters installed in the unit – either nano filters or ultrafilters.
​
LSI manufacturers a variety of ultrafiltration and nanofiltration unit to suit virtually any requirement. The manufacturing of ultra/nano filters is a very specialized process. Therefore, LIS does not manufacture the nano/ultra filter tubes themselves, they work with a number of well-established manufacturers to supply the actual filters. LIS will then incorporate these filters into a complete system.
​
​The chart below summarizes the types of particles that are removed from the water with each type of membrane filter. The green arrow indicates that the particle is small enough to pass through the filter, whereas the deflected orange arrow indicates that the filter blocks the particle from passing through the filter.
