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.
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.
Is magnesium hydroxide good for microbial wastewater?
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 advers ely 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.
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 magnesium hydroxide safe?
Magnesium Hydroxide will only solubilize and generate a pH up to around 8.5, rendering this chemical safe to use because the likelihood of burning out (pH above 9) the biological activity is nearly impossible. Magnesium Hydroxide does have some drawbacks.
What is Caustic Soda?
Caustic Soda is commonly referred to Sodium Hydroxide or NaOH. Surprisingly, it can be commonly found in the home but in the industrial sense, it is mainly used for alkaline neutralization. Caustic Soda is found in all kinds of concentrations and is a common, popular way to neutralize and tame all kinds of acids.
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.

Why alkalinity is important
Although you don't often hear about the alkalinity of your favorite lake in the news, alkalinity can be important to the health and welfare of a lake. The ecosystem and organisms that live in the lake evolved in water bodies that didn't change quickly. Before humans came along water bodies were not subjected to chemical spills and acid rain.
What affects alkalinity?
In a surface water body, such as a lake, the alkalinity in the water comes mostly from the rocks and land surrounding the lake. Precipitation falls in the watershed surrounding the lake and most of the water entering the lake comes from runoff over the landscape.

We need some alkalinity to buffer against drops in pH values. Processes that biologically produce acids or acidic chemicals include:
What is the ratio of volatile acid to alkalinity in an anaerobic digester?
In a properly operated anaerobic digester, the ratio of volatile acid to alkalinity is between 0.1 to 0.25 parts acid for every one part alkalinity per liter. If a digester is overfed and volatile acids are rapidly increasing, the methane formers can’t consume the acids fast enough.
What are the processes that drive pH down?
Biological processes like nitrification and anaerobic digestion rely on alkalinity. Without alkalinity, organic acids formed during these processes would drive the pH down to a point where the bacteria would be inhibited or could no longer survive.
What is coagulant addition?
Chemical coagulant addition (aluminum sulfate, ferric sulfate, ferric chloride) When these biological conditions occur in a treatment plant, or when acidic chemicals are added, the free hydrogen (H+) in the acid reacts with the negatively charged alkalinity, and the two effectively neutralize each other.
How much alkalinity is in water?
In some areas, the drinking water could contain 200 to 400 mg/L of alkalinity, as CaCO3-. Influent wastewater that contains roughly 200 to 250 mg/L of alkalinity as CaCO3- usually contains enough buffering capacity to prevent low pH values at the end of the treatment process.
How to measure alkalinity?
We measure alkalinity using test kits that contain reagents and dilute acid, or directly measure the pH while adding acid to a sample. Let’s look at measuring total alkalinity using the latter method, which is referred to in Simplified Laboratory Procedures for Wastewater Examination. It can be used to measure the alkalinity of samples like plant influent wastewater, plant effluent, mixed liquor suspended solids (MLSS), trickling filter and RBC fluids, and plant biosolids.
How to raise alkalinity in pool?
Here’s how to use it: 1 Test your pool water using a digital test kit or test strips to determine how much you need to raise the total alkalinity of the water. 2 A general guideline is adding 1.5 lbs. of baking soda per 10,000 gallons of water to raise the TA by 10 ppm. Remember, you’re aiming for a level of at least 80 ppm. 3 Wear rubber gloves and goggles for protection (baking soda in the eyes is not a fun time). 4 After you’ve measured out how much you think you’ll need, you can dilute it or add it directly to the pool. 5 Walking around the perimeter of the pool, pour in half or three quarters of the measured amount. We recommend adding it in stages, so that you don’t overdo it and potentially spike the TA and pH levels. 6 Wait 6 hours for the jets to fully circulate the baking soda in the pool. 7 Retest the water to determine the new TA level. If it’s still low, repeat the process until the desired level is reached.
How to raise pH in water?
Method #2: Use Soda Ash. Soda ash, otherwise known as sodium carbonate, is the other ingredient you can raise the water’s alkalinity level. While it does the same job as baking soda, soda ash tends to drastically raise both the TA and pH level, which can cause issues if the pH level doesn’t need to be increased.

Why does my pool water get acidic?
It can cause irritation to swimmers. When alkalinity is low, the pool water becomes acidic and makes it an irritant for swimmers that are exposed to it. Burning eyes and itchy skin will result, and some people can also suffer respiratory issues.
What happens when the pH of a pool is low?
When a pool’s alkalinity measures below 80 ppm it can cause unwanted side effects, including: Fluctuating pH levels. Wild swings in the water’s pH will occur if the alkalinity is low. This is also known as pH bounce, and is the result of the pool water not having an adequate buffer, aka the proper alkalinity level.
Why does chlorine drop alkalinity?
While they raise pH during shocking, the tablets themselves have a low pH level. As a result, using them will diminish your water’s alkalinity level .
How to increase alkalinity in pool?
An easy and safe way to give your pool an alkalinity boost is to use sodium bicarbonate. When you need to raise the pH, you can add sodium bicarbonate, but only if the total alkalinity of the water is also low.

What happens if you drink water with a pH of 7?
Water with a value greater than 7 indicates alkalinity and tends to affect the taste of the water. Alkaline drinking water may take on a “soda” taste. Corrosion problems also can occur in plumbing.
What happens if water is acidic?
The pH can also be affected by acid rain. Water with a pH value less than 7 is acidic and tends to be corrosive. Acidic water (low pH) can leach metals from plumbing systems, which can cause pipes to leak. Metals that leach from the pipes (lead from lead pipes or copper from copper pipes) may also cause health problems.
What does acid injection do to water?
Acid injection treats water with a high pH by lowering the pH of water to around 7, which eliminates the soda taste and can improve the effectiveness of chlorination. This method also reduces the potential of pipe corrosion as water with a pH above 9 can corrode metals such as brass, copper, zinc, aluminum and iron.
How to store sodium hydroxide?

How does soda ash work?
How soda ash/sodium hydroxide injection works. This treatment method is used if water is acidic (low pH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
Can you use sodium in water?
If water hardness is treated with sodium, it may be unsuitable for people on a low-sodium diet. In addition to water hardness, neutralizing filters may also cause water pressure loss due to the fact that the water needs to flow through finely ground neutralizing material.
