Your Performance Index: A Step by Step Maintenance Guide for Your Dualator System

Dualator® VI treatment systems require inspection and maintenance on a semi-annual basis. Filters with elevated iron or manganese in the raw water need more frequent maintenance. We’ve included a step-by-step maintenance guide below to ensure you are optimizing your system performance. Fill finished water storage tanks and/or tower. Backwash filters to a clean effluent. Shut off and lock out the [...]

Fall Back into Boiler Start-Up

As you send your children back to school and Halloween decorations begin to appear in stores, your facility operators may have already begun the process of preparing off-line boilers for the winter season. Regardless of if they were stored dry or wet, steps need to be taken to ensure a safe start-up of off-line boilers. Each boiler is different and prior to startup, and we recommend all engineers consult the boiler [...]

Your Performance Index: The Secret to Avoiding Mudballs

The presence of mudballs is an indication of problems in your filter bed. A mudball is the result of solids accumulating in a filter, then combine with filter media to form into a ball of solids. These mudballs block the passage of water, creating higher velocity filtration and uneven distribution. Mudballs impact filter performance and effluent quality while also shortening filter run [...]

Buyers Guide: Reverse Osmosis System

Are you interested in implementing Reverse Osmosis (RO) treatment into your industrial water treatment system? Prior to working with a professional to design your new system, there is some additional information that should be considered by your plant, as well as some information your RO manufacturer will need from you. We recommend working closely with your water treatment professional to assess your system [...]

Utilizing Calcite or Limestone Contactors for Remineralization Downstream from Membrane Treatment

Nanofiltration and reverse osmosis treatment reduce Total Dissolved Solids (TDS), incidentally lowering hardness and alkalinity in the process. If not treated further, this low alkalinity, low hardness permeate, can be extremely corrosive to downstream environments. Remineralization, the addition of hardness and alkalinity back into the water prior to distribution, can be a successful means of reducing this corrosion [...]

Your Performance Index: 7 Maintenance Tips for Your Air Supply System

Air Supply Systems consisting of compressors regulators, and receivers are a vital component to the successful operation of your water treatment equipment. To optimize air supply system performance, we’ve provided you with some maintenance tips to keep your system working efficiently.  Oil should be checked daily and maintained at the proper level. Oil should be changed per [...]

How to Avoid an Iron Related Bacteria Failure

Iron Related Bacteria (IRB) is a non-disease producing bacteria that can occur in a water supply when water carries bacteria from the well into treatment systems. While IRB contamination isn’t harmful, it can be nuisance. Iron bacteria are small living organisms that naturally occur in soil, groundwater, and surface waters. Iron bacteria is often found in close proximity to the well screen. The [...]

Your Performance Index: How's Your Paint?

Do you ever lay awake at night and wonder how your paint is looking in the interior of your vessels? Doubtful. Should you be inspecting your interior paint in your vessels? Absolutely. What should you be looking for? Corrosion and bubbling paint, paying special attention to check near the welds. So, why is this important? Paint issues can lead to leaks, eliminating the ability for the tanks to hold water, leading [...]

Your Performance Index: A Troubleshooting Guide for Your Bubbler Panel

A bubbler panel controls the liquid level within a filter vessel. A problem that can occur with bubbler panels is “valve hunting,” when there are large swings in water levels of six inches or more. When this happens there are two areas that need to be checked, the bubbler dip tube located within the filter cell and the reversing relay located inside the panel.  When [...]

Responding to a Legionella Event

Managing an On-Site Legionella Event Building owners are often faced with a decision to test the building potable and utility water for Legionella bacteria. The decision to test, how many locations to test, and how often to test, are best structured in a Water Management Plan (WMP) and are specific to each building. The WMP should be developed in accordance with the requirements of the ASHRAE 188-2018 [...]

Four Ways to Prolong the Life of Your Control System

The Programmable Logic Controller (PLC) is the heart of any treatment system, and a few simple precautionary measures can dramatically extend the life of your control system. One of the most important components to check and replace is the battery used for program backup in the processor. Manufacturers recommend that PLC batteries be replaced on a yearly basis. Plants can experience shutdown after a power [...]

Alternatives for Traditional Cleaning Methods Utilized in Fuel Ethanol Production

Bacterial issues in a fuel ethanol production plant can have expensive consequences, including increased chemical costs and eventually, revenue lost. It is common practice for plants to employ a clean-in-place (CIP) program to protect the product against bacteria. A traditional cleaning aid in fuel ethanol production is a 3-5% caustic solution (sodium hydroxide) used to reduce and remove organic fouling and soil [...]
