Cooling improves Lithium ion battery performance

Lithium-ion battery packs are the most commonly used batteries in electric cars, and their power output is dependent on several things: the number of cells that fit into the pack, and the effectiveness of the cooling system. A battery generates heat when it is discharged and can only maintain optimum performance within a certain temperature range. Therefore, thermal management is essential to consider before advances can be made in power output.

INTERN VIEW: How flocculation helps filtration

There are many types of pollutants that can contaminate water. One form of natural (not man-made) pollutant is from suspended particles in the water, such as silt, sediment, clay, algae, and oil. These particles remain suspended due to their likeness in ionic charge, negative in this case, causing them to repel each other and remain suspended. To treat water with suspended particles, the charge must be neutralized before gathering the particles into an agglomerate that can settle out of solution.

INTERN VIEW: What sets HaloKlear apart?

Eric Bradley-1During my interview with Eric Bradley, HaloKlear Product Line Manager, we talked about some of the unique features of HaloKlear products. They can be used in a broad range of scenarios and application types, achieve the same goals as synthetic chemicals, and is traceable in effluent water.

INTERN VIEW: Oil Refinery Case Study

There is a strong connection between how we produce our energy and how we manage our water resources; this week I wanted to take a closer look into some real-world applications of that concept. I was interested to learn how an energy company may have to deal with water treatment issues, such as a refinery having to treat its wastewater for oil. By looking through the water treatment case studies, it’s clear to see that Dober’s Natural Coagulants have a lot of experience doing just that.  

One case study I looked at was a large US oil refinery that wanted to increase environmental performance while cutting costs on coagulant usage in their wastewater processing units. The refinery was challenged with: the loss of a process water tank, a drive to improve environmental results at the wastewater treatment plant, and better cost control for the coagulant used throughout the refinery.

INTERN VIEW: History of Water Regulations

Interestingly enough, water regulations are a relatively recent development in human history. Not until the discovery of germ theory and how diseases spread did humans care much about what they dumped into waterways. Since science has shown us the effects of polluted water on human health and the environment, governments have created regulations on waterways to protect us and our surroundings.

This week, I took a look into the historical development of today's water policy in the United States.

Water policy varies by region; see these links for more specifics:

INTERN VIEW: Balsa River Hydroelectric Project

Having learned some technical information about the water treatment products, I decided I wanted to know more about their field applications. After looking through some case studies, I decided that I would focus on one in particular. The Balsa Inferior Hydroelectric Project on the Balsa River in Alajuela, Costa Rica caught my eye because the focus of my major is in energy, water, and environmental sustainability. This project highlights the cross section of all three aspects.

The Balsa Inferior Hydroelectric plant was completed in 2014 and is currently in operation as a 38 megawatt powerplant. This plant generates electricity by taking water down a 4 km tunnel into a set of turbines. After passing through the turbines, this system returns the water into the Balsa river. Dober was brought in to solve the problem of reducing the sediment load on all soil types while maintaining eco-friendliness.

INTERN VIEW: The benefits of using natural products

After learning about the differences between coagulation and flocculation and how Dober products work, I wanted to learn more about what sets HaloKlear water treatment products apart from traditional, synthetic ones.

By talking to Dr. Joe Drozd, Research Chemist in the water treatment lab, I have a better understanding of what makes Dober unique. Currently, much of the water treatment industry uses synthetic chemicals, such as Alum or Anionic Polyacrylamide (aPAM).

Dober's water treatment products are made from plants and chitosan, in other words, from renewable resources, and are not by-products of rare minerals or metals.  Being naturally-derived offers many benefits, particularly in environmental health and safety.

Is Chematic REACH 2018 Compliant?

Over the last couple years, it has been Dober's commitment to grow into the EU region and being able to comply with REACH 2018 is critical. 


As a global leader of detergents for industries requiring cleaning validation, Chematic has been sourcing raw materials and manufacturing locally in preparation to be REACH 2018 compliant. We have learned a lot along the way and are here to help answer any questions you may have.

Can You Supply One Universal Detergent to Clean All of My Products?

 We get this question all the time. 

We always try to come up with a single source solution if we possibly can. We are well aware and understand the cost implications and timing that it takes to validate a cleaning detergent.
