Better Chemistry. Better Business.


Under the Lab Coat with Bob MacDonald

Every month we shine a spotlight on one of our technical team members. This September you can get to know our wastewater Field Technical Service Engineer, Bob MacDonald. 

We sat down with Bob and asked him a few questions this month:

What is your work background:  “I have worked at Hubbard-Hall in the wastewater department for 43 years.”

Interests & hobbies: ” I enjoy fly fishing and also participate in clay target shooting.”

What do your main job duties involve? “I work alongside the sales force, distributors, and customers. I help them audit and review while recommending, installing and improving the performance of their wastewater treatment system by using Hubbard-Hall’s Aquapure chemistry.”

What is the most common WWT problem you come across?: “The most common wastewater treatment problem I come across is the lack of control and maintenance on the water treatment systems. The first step I usually take during a house call is an audit of the system. This will show us where the system is. We will then adjust it to where it should be, which could chemical or equipment related. We then observe if the adjustments improve the performance.”

A fact that most people don’t know about you: “As a much younger guy I owned and drove drag racing cars in the North East and Mid Atlantic tracks.”

Bob loves doing his part in maintaining our waterways, so he can keep up his favorite hobby.

What do you like most about your job?: “The favorite part about my job is all the different people I get to meet and work with.”

What is a recent wastewater challenge that you helped solve for a customer and how did you solve it? “I have been working with a shop that was using ferrous sulfate to control upsets and lower metal numbers when an upset occurred in the process. This lead to a very large volume of solid waste that was being produced. We discussed with the customer that they should look into our liquid cationic coagulant, AquaPure I-300. The customer agreed and they had successful results while it has controlled the upsets and significantly reduced the solid generation. The solid waste dropped from 5 cubic yards per week to a little over 2 cubic yards with the system in compliance. It was also much easier for the personal to work with.”
