4 Common Generators of Foam in Wastewater 

If foam is not monitored and kept at bay it can cause issues like inaccurate level indicators in tanks or the foam can grow so much that it escapes the tank, causing unsafe and slippery conditions. There are also different types of foam, it can be fluffy white foam that blows across the parking lot or dark dense foam that billows out of the manhole like a mushroom grown wild and it can also be somewhere in between the two. The trick to successfully treating foam is to figure out how the foam was generated.

Here are four of the most common reasons foam is generated:

  1. Mechanical motion in the water, such as aeration or mixers turning at high speed – We have all seen this one in action. Tanks
    usually have a light fine foam that is generated by air. This is normal, and if it stays light and dissipates, there is nothing to worry about.
  2. Heavy solids in the water – When the “solids-load” in your tank is too high, foam collageyou get a dense dark foam, as pictured on the right. This is serious and indicates a treatment issue that needs to be addressed. Once the solids load is decreased, the foam usually stops.
  3. Surfactants in water – Surfactants, a common ingredient in cleaners, can cause foam. There are two options to treat this type of foam. Option one is simple, replace the cleaner with a non-surfactant cleaner. This is not always an option due to cleaners being spec’d in or a resistance to change the current process. If you cannot stop the surfactant upstream, you must apply either a foam dispersion or anti-foam agent. These are commonly called defoamers.

12 Fun Facts of 2016

As the year wraps up, we will leave the singing of the 12 Days of Christmas to others. Instead, let us regale you with the 12 fun facts of 2016. Feel free to hum along.

Commodity & Specialty WWT Go Head To Head

 We put these two common wastewater options to the test to see where their strengths and weaknesses lie.

When selecting products for their wastewater treatment (WWT) needs, manufacturers must select between commodity wastewater treatment chemicals and specialty chemicals. A closer examination of their respective strengths and weakness will help illustrate what each has to offer.

Commodity Wastewater Treatment Review

Commodity wastewater chemistry traditionally involves products like lime and calcium chloride. While the price per pound may be less expensive, using basic commodity chemistry may not be the best or most cost effective option. This option requires the addition of single components or bags which take significant time to add, labor to move them around and bring them up to the Equalization (EQ) tank, and use of a higher dosage of chemicals. Commodity chemicals also produce a significantly higher amount of sludge that must be hauled off-site.

4 Requirements For A Reliable Rinsing Process

A quick list of the most important factors to bear in mind when determining your rinsing process.

Water is becoming an increasingly expensive commodity with even further restrictions in certain areas of the country (pity the poor folks in California). As a result, there has never been a better time to give some thought to maximizing the efficiency of your rinsing process. Put simply, rinsing is a process that dilutes and then removes surface films and contaminants, reducing them to a level that won’t impede your surface finishing process.

As one of the most important steps in any metal finishing process, it’s critical to have your metals rinsed regularly and properly. A truly effective rinsing process is essentially a matter of maximizing your system’s layout, choosing the right equipment, chemicals and slotting it in at the right time in your process cycle. Get this balancing act just right, and you can reap such benefits as water conservation, decreased the demand on your waste treatment system, and the continuing smooth operation of your process line.

Just the (Re)man for the Job: Preparing Your Core Parts in Remanufacturing

A brief introduction to remanufacturing and our quick n’ easy core preparation guide.

With the trend towards renewing, reusing and recycling in order to reduce costs, increase efficiency and strive for sustainability, Hubbard-Hall focused on providing its services to an industry that brings all three of these strands together: remanufacturing.

Remanufacturingreman + demo before and after pic, or “reman”, as a process goes far beyond just refurbishing parts. Remanufacturing is an industrial process that strips what are called core parts (such as automobile engines) down to their base components.

The cores are then cleaned and rebuilt to like new quality, sometimes requiring an additive manufacturing process similar to 3D printing technology to add metal directly to the core if they’ve been worn out over time.

That Summer Heat Brings Odor Issues

Controlling odor is one of the most challenging aspects of industrial and municipal wastewater treatment. This challenge is heightened during the hot summer months. The first step in fixing the problem is identifying where the odor is coming from. Here are a few places we recommend you start your search for that odor:

  • odor issue summer funnyRinse Tanks
  • Air Scrubbers
  • Pump Stations
  • Evaporator System
  • Sewer Lines
  • Grease Traps
  • Equalization Tanks

New Cleaning Chemistry Launched at SUR/FIN 2016

 

This year marked the 25th year Hubbard-Hall has attended the highly anticipated National Association for Surface Finishing (NASF) SUR/FIN 2016 conference. In celebration, we launched our new family of organic acid cleaners at the show which was held from June 6-8th in the Entertainment Capital of the World, Las Vegas. SUR/FIN is one of the most comprehensive manufacturing and technology trade shows that connects thousands of surface finishing professionals to the industry’s foremost business suppliers, latest innovations, and the most influential leaders. Throughout the 3-day event, members of our team enjoyed the multitude of educational conference sessions, keynotes, and being on the trade-show floor. 

We were particularly honored to be a part of the impressive educational program line up. Hubbard-Hall’s Senior Technical Service Engineer, Mike Valenti, had the opportunity to present during the ‘Light Materials Finishing’ session. The new type of cleaning chemistry discussed in Mike’s presentation is part of the new family of organic acid cleaners that we launched at the show. This product line has proven to increase productivity by 60%, and includes Aquaease 2289 soak cleaner, Aquaease PLA 915 spray cleaner, and Lusterbrite CBA mass finishing. The primary focus of Mike’s presentation was to educate the conference attendees on how to clean, deoxidize, and brighten non-ferrous metals in one step. (more…)
