Food & Beverage Industry – How to Specify Industrial Water Filtration Equipment in the Food Industry

Water filtration applications in a Food and Beverage facility

In a typical Food and Beverage facility there are many different water and process applications, each demanding its own specific level of water purity. The presence, flows and purity of each of these streams is driven by the Food and Beverage plant design, e.g. canning, dry-goods, soft-drink, brewery.

These can include:

  • Pre-treatment of well, surface or city water
  • Boiler water treatment
  • Condensate treatment
  • Process water treatment
  • Cleaning and sterilization service water
  • Hygiene Services
  • Waste water disposal.

Regardless of the application, there is a good chance that some type of industrial water filtration will be required in order for the Food and Beverage application to operate at its peak efficiency.  

Defining the Types of Water Filtration Systems

Water filtration options can be divided into two major categories, based upon the filtering media used

  • granular and
  • membrane.

Granular water filtration has been used for many decades in the Food and Beverage Industry, and will be familiar to most. Examples of granular media filtration include sand filters; activated carbon filters for taste, odor, and chlorine removal; anthracite filters; and fine garnet filters.

These types of filters can remove suspended particles down to about 10 microns in diameter (1 micron = 10-6 meters). With the use of certain coagulant or flocculation polymers fed prior to these filters (fed as filter aids), some success has been seen in the removal of particles down to almost 1 micron.

The spacing between the discrete filtering media particles serves as the pores. Suspended solids trapped out by these filters will be collected on top of the filtration media bed, or within the pores.

Membrane water filtration uses membranes to remove suspended particles. Unlike granular filters, the membranes are designed with pores and are capable of removing much smaller particles. The ultimate membrane filtration is reverse osmosis (RO), where dissolved solids (metal ions) can be removed. This is not really a filtration mechanism in the truest sense of the words, as the semi-permeable membranes used in RO do not have pores. It is more properly thought of as a demineralization mechanism.

Membrane water filtration is best characterized by the size range of the filterable particles, as follows:

  1. Microfiltration (MF) can include woven or wound depth-type cartridge filters, or true membrane filters. Can remove particles from about 0.1 micron to over 1 micron.
  2. Ultrafiltration (UF) can remove particles from below 0.01 microns to over 0.1 microns. Can remove some large molecular weight organic dissolved material.
  3. Nanofiltration (NF) can remove particles from below 0.001 microns to 0.01 microns. Can remove smaller molecular weight organics.
  4. RO can remove particles from 0.0001 microns to 0.001 microns. Can also remove DISSOLVED IONIC SOLIDS.

What Are Steel Tubes & In Which Industry Type They Are Most Utilized?

What is steel tube?

There are the pipe like structure made up of different alloys like Manganese, Aluminium, Tungsten & Titanium. They are strong, tough & durable in nature and are often moulded in rectangular, round & square shape. They say – every year around tonnes of steel tubing’s are manufactured – as it has vast application in various construction industries.

Types of steel tube

They are of two types – seamless & welded. Molten steel is passed through the piercing rod to convert them in hollow-shaped seamless steel tubes. Welded steel ones are manufactured by rolling and curling a steel plate and welding it at the seams to provide it strength & endurance.

In earlier times, seamless tubes were considered as robust & stronger than welded ones. But with advances in technology, now welded ones are also sufficiently strong and are being used for many industry-specific requirements.

Application of steel tubing in different industry/domestic setting

Steel tubes are comprehensively used now in industrial & domestic settings. In industry settings, they are valued & utilized for their extreme endurance and capacity to withstand destructive elements, sudden temperature and pressure of environmental forces. In domestic settings, they are utilized for the gas pipes and is embedded inside the appliances, even in the refrigerator, there is a steel pipe.

Top industries where steel structures are highly utilized

These steel pipes are mostly utilized in construction/ engineering field and automobile manufacturing field.

In Construction & Engineering

• The industrial settings HSS (hollow structural sections) tubing’s are either circular, rectangular or square (suiting to the industry’s requirement).

• The ones that are circular are called CHS (circular hollow structural), square ones are called SHS (square hollow structural) and the rectangular ones are called RHS (rectangular hollow structural).

• On construction sites, they are used to manufacture metal scaffolding which are used to make the movement of workers and the heavy equipment or materials with ease. The best part, these structures don’t require the nuts & bolts to bring the structure in one whole shape.

• Circular & square HSS are often used for making the columns of a structure, whereas, rectangular HSS is commonly used in welded frames.

In Automobile Manufacturing

• The steel tubing in the automobile industry are on hype these days ever since the early 90’s.

• In such settings, they are often used to manufacture parts of the automobile or various vehicles.

• The suspension, vehicle control systems & fuel injection parts are made using the industry-grade steel tubes only.

LiFePO4 Batteries For Material Handling Industry

Are you looking for a battery that will provide you better performance, safety and durability, all in one? Then LiFePO4 batteries are the perfect choice for you. These batteries are also cost effective and offer a myriad of benefits to the user. They find efficient application in solar lighting systems, vehicles and household appliances.

  • Features of a LiFePO4 battery

This is a lithium ion battery that comprises lithium iron phosphate as the cathode material. As anode it makes use of carbon electrode with a metallic coating. The battery has a specific power about 2000 W/kg so that it can perform efficiently. It requires only 3.2 V to operate. It can be used consistently for 10 years because of its high stability. The battery can be utilized to generate energy for 2,000 cycles.

LiFePO4 batteries come coated with carbon nanotubes that confer excellent electrical conductivity. These batteries are less harmful due to their nontoxic nature. They are thermally stable and quickly rechargeable. For high quality performance, LiFePO4 batteries have inbuilt capacity of 170 mAh/g.

They can be purchased at a reasonable price because their chief raw material is Iron which is available in abundant quantities in nature.

  • Benefits Of A LiFePO4 battery

The reasons to choose LFP batteries over other common lithium ion batteries are many. The main plus point is that they deliver better and more advantages than others. For example if you take a lithium cobalt oxide battery you will find that it has less specific capacity and power rating than a LiFePO4 battery. Also, the use of cobalt in battery manufacture causes pollution at many levels. But in LiFePO4 batteries cobalt has been successfully replaced by phosphate that prevents our exposure to toxic cobalt. So, why to put your family and that environment at risk while disposing a LiCoO2 battery?

LFP batteries present longer cycles than the rest. They provide the quality of nickel based batteries by running at a constant voltage throughout their life span. The steady voltage of 3.2V allows the battery to consistently supply the maximum power to devices unlike other lithium batteries whose capacity declines with age.

You can even use your LFP batteries as a safer alternative instead of lead-acid batteries which are used heavily in transportation. This is possible by stacking 4 LiFePO4 batteries in a series arrangement, but you must be extra careful while charging this setup to prevent it from overcharging and resulting in damage.

LFP batteries are the perfect choice for your back up power or UPS, because they will not get damaged like other lithium ion batteries when kept in standby mode.

LFP batteries are guaranteed to provide you consistent efficiency over the years as they are designed to lose their energy density at a slower pace.

  • Are LFP batteries the safer choice?

Lithium cobalt oxide batteries contain cobalt as a significant component which has a resistance with negative temp coefficient that poses the risk of thermal instability. The chemistry of LiCoO2 allows spontaneous combustion if overcharging takes place. Even a short circuit can result in an explosion.

But LiFePO4 batteries contain phosphate that makes the battery structurally more stable. This ensures your safety while charging, because these batteries rarely get ignited during charging or short circuit.

  • Wide utility of LiFePO4 batteries

LFP batteries come handy for many purposes such as LiFePO4 transport, lighting, etc as well as for running household gadgets.

These batteries are suitable for bicycles and electric automobiles, since they facilitate better acceleration due to a higher discharge rate. Today, they are being extensively used in electric passenger cars, garbage trucks and hybrid military vehicles to list a few.

The unique properties of LiFePO4 batteries such as resistance to unstable climate and faster recharge make them the ideal fit for solar applications. People are using them in solar panels, street lights, lamps and inverters because of their compact, lightweight nature with tolerance to overcharging.
