Why is lime used in phenolic water?
This application of lime is utilized where "phenolic water" exists, because chlorine treatment tends to produce unpalatable water due to the presence of phenol. This process, called 'excess alkalinity treatment', also removes most heavy metals.
What is hydrated lime?
A very common product, also known as hydrated lime or CaO quicklime, lime can be ‘slurry-ized’ through the addition of water to dry lime powder. This slurry can be used to treat wastewater to increase pH and alkalinity and is commonly used in potable water to “soften,” or remove hardness minerals, such as calcium and magnesium from drinking water.
Why use lime slurries?
Lime slurries minimize the effects of potential scaling in the water distribution system. It is also the most commonly used product to maintain alkalinity levels because of its low cost and multiple treatment benefits, such as assisting in the removal of manganese and iron from water.
What are the three main options for alkalinity treatment?
With so many options for treating alkalinity, there are three main options that are typically represented in the marketplace for Wastewater Treatment Plants (WWTP) when faced with this question: magnesium hydroxide, lime slurry, and caustic soda. The following outlines the good and the bad of each, hopefully providing needed guidance for decision-making at WWTPs. Ultimately, the choice lies within the final requirements of the plant and driven by the discharge permit at the facility.
Does caustic soda raise pH?
Caustic Soda and Lime Slurry are definitely go to chemistries for the WWTP industry and they do provide the needed pH adjustments required. But on a pound to pound basis there is a fundamental difference between those two and magnesium hydroxide to also consider that does not have much to do with pH or alkalinity, but rather the true amount required to treat. For example, a given water sample may require 100 mg/L of magnesium hydroxide to raise the pH to 8.8. For the same sample, 138 mg/L of caustic soda and 135 mg/L of lime would be required.
Is lime slurry harmful?
The downside of lime slurry originates from its high solubility. Maintaining proper pH levels often becomes biologically prohibitive before ideal alkalinity levels and process stability can be reached. Another major concern is lime slurry will cause an increase in waste sludge, sometimes as much as 50% – adding more disposal costs to the operation. If that wasn’t already enough, hydrated lime slurry added in collection systems increases the operations and maintenance costs related to formation of scale and accumulated solids/sludge. In severe cases this can lead to line blockages.
Is magnesium hydroxide good for microbial waste?
So, comparing magnesium hydroxide, caustic soda, and lime slurry, while all can supply the required benefits, the whole treatment process should be reviewed and determine the best overall solution based on some of the side effects for each. Magnesium hydroxide can be difficult to store when not done properly but can supply significantly more alkalinity in a bio-available form to a microbial wastewater system without adversely affecting pH . This creates a more suitable environment for bioremediation of BOD and nutrients like nitrogen and phosphorus. Moreover, because magnesium hydroxide supplies a lightweight, divalent cation, unlike the monovalent sodium in caustic and heavier calcium in lime, magnesium hydroxide helps to generate a denser, more easily dewatered sludge, with a higher percentage of cake solids – reducing waste disposal costs.
Why does my lawn need lime?
Soil pH changes for many reasons, including the lime or other products you add. In areas with heavy rainfall, calcium naturally leaches away as rainwater passes through soil. The loss of calcium means soil pH drops and soils become acidic over time. In these regions, lime is usually a necessity for healthy lawns.
When is the best time to use Pennington lime?

What happens when soil is too acidic?
When soil becomes too acidic, lawn grasses struggle and plants that flourish in acidic soil take their place. For example, the presence of lawn moss signals your soil pH has become too low for strong, healthy grass growth. Other warning signs include increases in common lawn weeds, diseases and insect pests. Many weeds prefer acidic soil, and low soil pH can inhibit the effectiveness of some herbicides and insecticides. 2 When soil is overly acidic, you'll also notice that grasses don't respond to quality lawn fertilizers with the healthy, lush growth you normally expect.
Why does soil pH change?
Soil pH changes for many reasons, including the lime or other products you add. In areas with heavy rainfall, calcium naturally leaches away as rainwater passes through soil. The loss of calcium means soil pH drops and soils become acidic over time. In these regions, lime is usually a necessity for healthy lawns. In areas with very little rainfall, calcium doesn't leach away, and lawns can become too alkaline. Proper lawn maintenance also naturally lowers soil pH over time. Regular fertilization, proper irrigation and increased activity of beneficial soil microorganisms all contribute to gradual, normal drops in soil pH. 2
What is lime made of?
Lime is a soil amendment made from ground limestone rock, which naturally contains calcium carbonate and magnesium carbonate. When lime is added to soil, these compounds work to increase the soil's pH, making soil less acidic and more alkaline. Even though lime includes calcium and magnesium, which are essential nutrients for healthy plant growth, it's not a substitute for fertilizer. Lime's primary role is to alter soil pH and offset soil acidity, which can improve the availability of plant nutrients.
Does lawn maintenance lower pH?
Proper lawn maintenance also naturally lowers soil pH over time. Regular fertilization, proper irrigation and increased activity of beneficial soil microorganisms all contribute to gradual, normal drops in soil pH. 2.
