Arc Flash Training Held at Res-Kem

Arc flash training, an OSHA required session to help identify the risks around working with electrical and signal wires, was given to twenty people with our organization.  It helps the technicians fully understand the risks, and how to determine if there is any stored energy before starting work.

Injuries that can result from an arc flash:

• Burns
• Respiratory system damage
• Hearing damage
• Skin penetration from flying debris
• Eye and face injuries

We covered the risks with performing the work, Lock-Out Tag-Out (LOTO,) testing methods and Personal Protection Equipment (PPE). The twenty people trained included plant and field personnel that have not yet completed this certification class, including field service technicians, in-house assembly personnel, and field sales engineers.

What is an arc flash?

According to Wikipedia:

"An arc flash is an electric arc supplied with sufficient electrical energy to cause substantial damage, fire or injury. ...  Arc flash temperatures can reach or exceed 35,000 °F or approx 20,000 °C at the arc terminals. The massive energy released in the fault rapidly vaporizes the metal conductors involved, blasting molten metal and expanding plasma outward with extreme force. A typical arc flash incident can be inconsequential but could conceivably easily produce a more severe explosion ... .  The result of the violent event can cause destruction of equipment involved, fire, and injury not only to the worker but also to nearby people."

Industrial Water Softener Shipped to Repeat Food Flavorings Customer in New Jersey

Res-Kem recently shipped a second 84 inch industrial water softener to the same food flavorings plant in southern New Jersey. The water treated by the water softener is used to make steam to sterilize the raw plant material prior to extraction and to extract the flavoring. The softener is the replacement to a second existing tank which has failed after 40 years of service.

Second 84"Water Softener prior to Shipment to Food and Flavorings Plant

Emptying and Removal of Old System:
Before the system was shipped, our service team coordinated their work with the company's mechanical contractor to remove the resin and gravel from the existing, corroded system. Our service team brought our trailer mounted diesel vacuum system to remove the media and prepare for disposal by the customer. After we were finished, the old system was cut apart for scrapping by the contractor.

Vacuum Trailer used to Remove Ion Exchange Resin
and Gravel from Existing Water Softener

New System:

The new system is an 84" diameter steel vessel and is finished in an epoxy coated interior and exterior. The customer asked us to change our normal blue color to red.  We hope to provide the white tank next fiscal year (do you see the theme??)  We also were asked to change the face piping to Schedule 10 304 stainless steel. As before, the valves are Bray valves with Bray air-to-air actuators. The system is controlled by an Aquamatic 962 controller. At this point, regeneration will be initiated manually when production will allow. To handle the existing uneven floor, four jack legs were provided.

System Operating Parameters:

Since most of the steam ends up in the plant matter and the extracted flavor ingredient, very little steam condensate is returned. This make the makeup flow very large. Each of the three softeners operate at 200 gpm and 80 psig. Because to the system's age, corrosion of the tanks and piping have become a maintenance nightmare.

Amazing Craftsmanship of Condensate Polisher from Res-Kem

I need to acknowledge the excellent, American craftsmanship which goes into our condensate polishers!  It may be the engineer in me, because this is an amazing piece of work!  My kudos go to:

• Tony, our Lead Design Engineer who had to design the vessel, the vessel penetrations, pad flanges, internal clips and its internals with amazing accuracy (and I am certain a few sleepless nights!). 
• Shane, our Lead Assembly Person who had to go into this vessel and assemble Tony's creation, piece by piece day after day. 

This attention to detail is particularly admirable when it is likely no one will see ever see these distributors, header and laterals again! 

As we know, the things you cannot see separate the highest quality product from others.

• Inlet distributor
• Brine Distributor
• Sub-surface was distributor
• Hub and Lateral underdrain

You have too realize everything you see takes place in a 54 inch diameter tank that is approximately 84 inches tall!  Shane had to squeeze through a 14 inch x 18 inch elliptical manway and Bill, who assisted Shane, had to give each piece to Shane through the same manway!

Greensand Filters Shipped to Western PA Water Plant

A western Pennsylvania, small private water utility, recently received four greensand filters to replace the filters that were failing.  Unable to get the original manufacturer to provide new, duplicate units, our customer found our website. 



Four New Greensand Filters and Greensand Media Ready for Shipment to Water Utility



Because of State regulations, the systems and their operation needed to be as close to the original as possible, otherwise new permits would be required.  Since Greensand is in very, very short supply, the media was changed to Greensand Plus from the same manufacturer.  Sodium hypochlorite is used to continuously oxidize dissolved iron in the water coming into the filters.  Also, these filters are very unique because they are much shorter than we normally manufacture.  Our normal tank straightside is 60".  These tanks are 36" straightside.  

Three of Four Existing Manual Greensand Filters Showing Tank Corrosion

What does the company do? Public water

What is the Res-Kem water treatment application? Green sand filter to removed dissolved iron


What are the savings and/or ROI the customer wants to achieve? Not applicable.  The customer is replacing old existing system with identical system


What are the operating conditions, e.g. flow, temp, continuous, etc.? 60 gpm, Well Water Intermittent Flow

What is the system configuration, e.g. # of tanks, standby units, etc.? Four greensand filters in parallel operation


Materials of construction of tanks, piping, valves, frame, etc.? ASME Code Steel Tanks, 6’ Diameter X 36” Shell straight-side , PVC glued with manual ball valves


Type of valves and actuators? Manual ball valves


Control philosophy? Backwash as required based upon differential pressure

Special Features? Short fat tanks, required to fit tight area

Iron and Manganese Removal Filter Shipped to Westchester County HQ

Res-Kem recently shipped a 52 gpm dual tank greensand filter to a Westchester County New York corporate headquarters campus.  This filter uses greensand to remove dissolved and precipitated iron and manganese from the water coming from the local public water system.

Dual 36" Greensand Filters with
Bray 31 Valves and Bray Series 93 Pneumatic Actuators

Water Problem:

At a Westchester County corporate headquarters campus, about 4 to 5 times a year, our customer experiences water quality and quantity problems. The campus receives its water from a local public water supplier. High levels of iron and manganese are present within the public water distribution system, and peak flow events such as hydrant flushing or firefighting activities have caused brown water to be drawn into their water system. What exacerbates the problem is the campus is at the end of the water distribution system without looping.

Therefore, iron and manganese laden sediment accumulates the piping and is drawn into the campus drinking water system. Res-Kem designed and constructed a filtration system to remove iron and manganese from the drinking water, as well as a storage tank. The volume of the tank is 150,000 gallons which provides two days of storage in the event of a water emergency with the water supply.


System Solution:

Inlet Iron and Manganese:	Average Inlet Iron 0.22 mg/l Average Inlet Manganese 0.11 mg/ml
Flow Operating Conditions:	Typical: 52 gpm typical
System Configuration:	Dual Parallel 36" diameter ASME Code, carbon steel tanks Epoxy Lined, NSF 61 certified Schedule 80 PVC face piping Differential Pressure Switch initiated backwash Greensand Plus filtration media
Control Valves:	Bray Series 31 valves with Bray Series 93 actuators
System Operation:	Differential Pressure Switch initiates backwash cycle
Added Features:	Domestic water booster pumping system brings filtered water backwash to system Sodium Hypochlorite (NaOCL) serves as the chemical oxidant for the removal of iron and manganese in the filtration system. The NaOCL will be injected immediately upstream on the system influent piping header. Chemical dose will flow paced based from the signal from the filtration systems influent flow meter.
