Walnut Shell Polishing Media

Walnut Shell Polishing

WALNUT SHELL POLISHING MEDIA

Walnut shell polishing media is a hard and fibrous product made from crushed walnut shells in accordance with International Trade Standard. The walnut shell polishing medium is ground to various sizes from coarse to extra fine depending the application, allowing for a fine degree of control over the desired finish. Walnut shells are used in many polishing and/or deburring applications.  Walnut shell media is used for polishing or cleaning fine metals, alloys, mechanical parts, shell cartridges, eye glass lens, rocks, stones, coral, ivory, beans, and seeds. Walnut shell is used as an polishing media similar to sand for polishing or deburring but without the negativities associated with other abrasive materials. Because walnut shell polishing is a gentle, non-corrosive environmentally friendly method of removing burrs, splinter, rusts, wets, edges and corners, without scratching, etching, pitting the substrate material / underlying surface or marring cleaned areas. When used as a polishing media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a 'soft polishing media'. Walnut shell polishing media is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
Like other soft polishing media, Walnut shell cleans and removes matter from surfaces without damaging underlying material.
Suggested mesh sizes are 4/6, 6/10, 8/12, 12/20, 14/30, 18/40, 35/60, 40/100, 60/200, #100, #200

Walnut Shell Filtration System

Walnut Shell Filtration System in Oil Field

Why needs the walnut shell filter?

Clean water is important to the oil and gas industry. As oil fields mature, their water cut steadily increases. After the separation process, the liquid will always contain some residue oil. 

Fats, oils and greases content of waste water can cause many problems in both sewers and waste treatment plants. If oil or grease is not removed before discharge of the waste. It can interfere with the biological life in the surface wasters and create unsightly floating matter and films.

The acute effects of oils on birds, fish and microorganism are reasonably well cataloged. The potentially more harmful is the subtle effect on other aquatic life.

The food industry seeks effective technologies to remove fats, oils and greases. Manufactures of oil containing foods face the problem of reducing the oil containment load to downstream waste water systems. 

A large amount of water is used in the refinery processes and a big fraction of it comes out as waste after getting polluted by oil which enters into the wastewater from leaks, spills etc., at various stages.

Walnut Shell Filter Applications

Walnut shell filters are frequently installed for the removal of oil and suspended solids from produced water, refinery effluent and waste / re-circulation streams found at other industrial applications. Walnut shell filtration system is developed as a more suitable method of filtering free oil and suspended solids in applications where sand filters have traditionally been used. Today, walnut shell filter is used to treat oil field produced water, refinery waste water, steel mill direct spray and caster water, ethylene plant quench water, copper concentrate decant and cooling water. 

In water and waste water applications, walnut shell filters are used to remove suspended solids and insoluble hydrocarbons from oily waste water, groundwater, plant process water, cooling water, water recycling & re-use, produced oilfield water and refinery waste water. In metalworking, power generation, municipal, chemical, and petrochemical applications, walnut shell filter treat and remove suspended solids, oily residues, ash, and metallic hydroxides from industrial liquids. Especially suited for filtering water used for oil field flooding, refinery disposal and off shore disposal. Also chemical agents are not needed during filtration.

But they are especially valuable in offshore drilling applications, because they are small and light enough to be installed on a ship due to the reduction in backwash water volume and reduction in weight and footprint. The walnut shell filter will play a big role in helping offshore rigs meet new and more stringent water quality regulations. Best of all, a special backwash cycle can safely remove the contaminants from the walnut shell filter media, allowing the walnuts to be used again and again.

Walnut shell is used for the filtration of water as environmentally safe and effective filtration media. Walnut shell is the best technology for the removal of oil and grease, as well as suspend solids from a variety of heavy oil and other oilfield produced water streams. Walnut shell is chemically inert, hard, resilient and perfect for oily water processing. Suggested mesh sizes are 6/10, 12/20, 35/60, 40/60.

Walnut Shell Working Principle in Filtration

Walnut Shell Filter Operating Principle

The walnut shell filter uses a deep bed of 100 percent walnut shells as the filtration media, which have excellent surface characteristics for coalescing and filtration, plus superior resilience to attrition. This deep bed of 100 percent walnut shells offer superior effluent quality, longer filtration runs, and greater throughput efficiency. The walnut shell filter removes about 98% of oil contaminants and suspended solids from a water stream.

The walnut shell filter uses raw process water and gas or air for back washing, eliminating the need for moving mechanical equipment or external scouring equipment. The walnut shell filter operates at twice the flux rate of conventional sand filters in the same application, and can remove over three times the amount of solids before needing to be cleaned.

Walnut Shell Deep Bed Filtration Media

Walnut Shell Filter Features

Walnut shells have a natural affinity for oil. The same English Black Walnuts that we routinely crack and eat can be ground up and used to safely and efficiently clean up contaminated water streams. 

Walnut shell filters are simple and reliable, compared to many filtration techniques designed to remove oil contaminants and suspended solids from water. There are no chemicals, very few moving parts and the walnut shell filter media can be used over and over again. Walnut shell filters can take water with up to 100 parts per million of contaminants and reduce this level to under 5 parts per million. This is cleaner than normal drinking water.

Couple this with the fact that walnut shell filters can be specifically designed for offshore use to remove more than 98 percent of the contaminants passing through it,

The following is the walnut shell filter advantages:

• Positive media cleanup  
• Elimination of compulsory chemicals  
• No requiring clean water 
• Simple, automatic design  
• Up to the minute, state of the art technology 
• No air or gas scour required 
• Upstream flow is not interrupted 
• High flow rates 

Walnut Shell Filter Backwash

Walnut Shell Filter Operation

During the filtration cycle, dirty process water passes through the walnut shell filter from top to bottom. As the water passes through the walnut shell media, free oil and suspended solids are removed. After 24 hours of filtration, the dirty process water is redirected and pulsed into the bottom of the vessel to fluidize the media bed. In addition, air or process gas is added in a proprietary manner to create an airlift pump.

The airlift pump lifts the contaminated media to the top of the vessel where the turbulence of the backwash water and gas separates oil and suspended solids from the walnut shells. The use of air or gas greatly reduces the amount of backwash water required. The mixture of air or gas and backwash water is separated in an external vessel. One separator vessel can be used for multiple walnut shell filters. Upon completion of the backwash cycle, the flow of dirty process water is again returned to the top of the vessel. It utilizes unfiltered water for media cleanup, eliminating the need for high volumes of clean water.

Walnut Shell Blasting Applications

Walnut Shell Blasting Media

WALNUT SHELL BLASTING MEDIA

Walnut shell blasting media is a hard and fibrous product made from crushed walnut shells in accordance with International Trade Standard. The walnut shell blasting medium is ground to various sizes from coarse to extra fine depending the application, allowing for a fine degree of control over the desired finish. Walnut shell is used as an abrasive blast media similar to sand for cleaning, but without the negativities associated with other abrasive materials. Because walnut shell blasting is a gentle, non-corrosive environmentally friendly method of removing foreign matter, coatings, paint, dirt, grime, mold and smoke residue from almost any surface including metal, wood, aluminum, brass, stone, glass, fiberglass, plastic, masonry and tile without scratching, etching, pitting the substrate material / underlying surface or marring cleaned areas. When used as a blasting media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a 'soft abrasive'. Walnut shell blasting media is also great for rust free paint removal from sheet metal and for cleaning engines, steam turbines and transmissions. Walnut shell blasting grit is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
