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 [...]

3 Easy Steps to Start Conserving Water Today

Warm summer months lead to higher water usage due to vegetation watering (lawns and gardens), pool filling and maintenance, and cooling system usage for indoor temperature control. Practicing responsible conservation habits during the season, and throughout the year, will not only support the ecosystem but also help lower your utility costs. Are you looking for ways to save on your water usage this summer? Here [...]

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 [...]

3 Things You Need to Know About Traditional Greensand Media

This versatile media is very user friendly but does require periodic maintenance. Traditional Greensand has a differential pressure limit of 8 psi for pressure filter applications. Exceeding this limit may damage your media. (Note: Greensand-plus, the newer generation is less sensitive to differential pressure). The optimal pH range for traditional Greensand is 6.2 to 8.5. Raw water with a pH lower than [...]
