Frequently Asked Questions

Boiler Water Treatment

Q: Why is boiler water treatment required?

A: There are many common issues which can occur if you do not treat the water in your boiler system correctly. Letting these issues build up will inevitably lead to a breakdown:

Boiler corrosion: water contains oxygen which will eventually lead to the thinning and pitting of the metal pipes. This can interfere with the heat transfer abilities of the boiler and contamination of the water itself. Suitable boiler water treatments will eliminate oxygen from the water and help prevent corrosion.


Impurities: water quality is a vital aspect of proper boiler functionality. A boiler with excessive impurities in the water will eventually break down as it can no longer function fully. Proper treatment will break down impurities and restore full function.


Foaming (carry-over): a high concentration of solids in the water will lead to frothing or foaming on the surface of the water. When this water evaporates as steam it can cause deposits in valves, heat exchangers, turbines, and super heaters, and strip away the magnetic layer in steam lines. This can result in the general corrosion and reduced function of your system. Treatment can reduce the occurrence of foaming and prevent these issues.


Reduce suspended solids: corrosion, scaling and impurities in the water cause an accumulation of solids which can pose a number of problems within the boiler. Hard water: hard water can develop inside the boiler and eventually cause a build-up of scale deposits, leading to impurities in the water. Water softening treatment is one of the most common and vital parts of boiler treatment.

All of these issues, if not properly prevented or left untreated, can leave you with thousands of pesos in repair costs, as well as stranding your facility without hot water.

Q: If the feed water for the boilers contains dissolved gasses such as oxygen and carbon dioxide, what outcome can we possibly expect inside the boilers?

A: These gases (oxygen and carbon dioxide) are aggressive instigators of corrosion, therefore, we can expect corrosion to happen inside the boilers. The severity of corrosion though, will depend on the amount of dissolved gases in the feed water, operating temperature and operating time of the boilers.

Cooling Water Treatment

Q: How do I Clean and Maintain a Cooling Tower System?

A: Keeping your cooling towers operating properly requires regular cleaning and maintenance to prevent microorganism growth. Unless you currently have a maintenance plan that includes cleaning, you are not doing enough to keep your tower working as it should. In addition to harboring bacteria, dirty cooling towers can draw debris through piping, reducing the efficiency of the entire system.

Q: Why should you clean your cooling tower?

A: Leaning your cooling tower and treating the water inside will prevent damage from happening to your entire system due to clogs and corrosion. Even if you regularly have the water treated, you still need to clean the tower to help keep the system free of bacteria and microbes.

Q: In cooling towers, what can be the effect of fouling in media by scale, mud, biologicals and debris, and how can this be addressed?

A: The effects of Scale, mud, biologicals and debris all impede distribution of water flow in the media. Improper water flow causes changes in evaporation and Delta T, thus decreasing efficiency. 


For fouling in the media, a comprehensive water treatment program will address the biologicals with biocides. For scale, mud and silt, this can be solved through a proper combination of dispersants, bleed-off and in some cases filtration.

Q: In the operation of cooling towers, why would we need to consider replacement of broken or damaged Fillers?

A: Broken or damaged Cooling Tower Fillers not only can impede water flow but it can also reduce the overall heat exchanging efficiency of the cooling tower.


In the chiller side of a cooling tower system, what can be observed if there is fouling from mud, biologicals or scale and what can be done to remedy this?


Fouling causes poor heat transfer and high approach temperatures, thus reducing energy efficiency. Chemical cleaning followed by mechanical cleaning of chiller tubes can solve this type of problem. Also, improving water chemistry of make-up water to prevent future problems. Adding filters can also help.

Wastewater Treatment

Q: What is wastewater, and why treat it?

A: We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment.


Wastewater treatment is also called “sewage treatment.” Nature has an amazing ability to cope with small amounts of water wastes and pollution, but it would be overwhelmed if we didn’t treat the billions of gallons of wastewater and sewage produced every day before releasing it back to the environment. Treatment plants reduce pollutants in wastewater to a level nature can handle.


Wastewater also includes storm runoff. Although some people assume that the rain that runs down the street during a storm is fairly clean, it isn’t. Harmful substances that wash off roads, parking lots, and rooftops can harm our rivers and lakes.

Q: Why Treat Wastewater?

A: It’s a matter of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:


FISHERIES: Clean water is critical to plants and animals that live in water. This is important to the fishing industry, sport fishing enthusiasts, and future generations.


WILDLIFE HABITATS: Our rivers and ocean waters teem with life that depends on shoreline, beaches and marshes. They are critical habitats for hundreds of species of fish and other aquatic life. Migratory water birds use the areas for resting and feeding.


RECREATION AND QUALITY OF LIFE: Water is a great playground  for us all. The scenic and recreational values of our waters are reasons many people choose to live where they do. Visitors are drawn to water activities such as swimming, fishing, boating and picnicking.


HEALTH CONCERNS: If it is not properly cleaned, water can carry disease. Since we live, work and play so close to water, harmful bacteria have to be removed to make water safe.

Q: Why do you need to treat the wastewater before releasing it to an outside body of water?

A: Effluent is the term used to describe the waste water from a certain industrial establishment that has been treated prior to releasing to the environment. Likewise, waste water is a collection of liquid/sludge that has no further use. The quality of wastewater does not meet the standards of DENR for it to be safely released into a body of water. Hence, you need a series of treatment processes which utilizes various chemicals to ensure that the effluent to be released meet the environmental requirements.

Q: What is Coagulation and Flocculation in wastewater treatment?

A: Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles.

Q: What are the advantages and disadvantages of using the Coagulation and Flocculation technique?



Simplicity and cost-effectiveness

Separates many kind of particles from water

Enhances filtration process

Uses abundant and low cost chemicals



Input of chemicals required

Qualified personnel required for design (e.g. construction of chambers and dosage of chemicals) and system maintenance

Transfer of toxic compounds into solid phase and formation of sludge that has to be treated subsequently

Relatively time consuming process

Q: What is a Jar test?

A: Jar test is a pilot-scale laboratory test that simulates coagulation or flocculation with differing chemical doses. The purpose of the jar test is to estimate the minimum coagulant dose required to achieve certain water quality goals. Jar tests are conducted on a four- or six-place gang stirrer, which can be utilized to simulate mixing and settling conditions in a clarifier.


Jar test helps to determine the right amount of treatment chemicals: the lowest dose of chemicals that provides satisfactory settling is the dose used to treat the water. 

Ion Exchange Resins

Q: Why should I use Ion Exchange resins?

A: Ion exchange resins are useful for the removal of water problems including hard water, scale buildup, nitrates and arsenic. Ion exchange resins are useful for the removal of water problems including hard water, scale buildup, nitrates, arsenic and more.

Q: What primarily causes hardness in water and how can this be removed?

A: Calcium and magnesium ions or compounds cause hardness in water.  These components can be removed by using softener or ion exchange systems.

Descaling Services

Q: Do I need to Descale my equipment?

A: We take numerous things for granted in the hustle and bustle of our daily lives. More often than not, we don’t give much thought to our boilers, cooling towers, power plants, condensers and heat exchangers.


What we don’t realize is that these hardworking equipment have to be descaled from time to time to keep them at optimal working capacities.

Q: What are common  and important reasons for descaling?


1. To keep systems more efficient and prevent the breakdown of operations.

Descaling is crucial to keeping operations going. For instance, power plants require the use of many boilers, condensers, cooling towers and heat exchangers – parts where scale is likely to build. Scale buildup will clog pipes, which in turn will force pumps to work harder to push water past the developing scales. If not descaled, the build-up might result in equipment failure, which in turn might cause the entire plant to be shut down for repairs.


2. Periodic descaling helps prevent Legionnaire’s disease bacteria.

Chiller tubes and cooling tower systems have to undergo regular descaling. Cooler tubes often become caked with algae, mud, scale and sludge. These also develop in the water that accumulates in a cooling tower’s basin floor. Unfortunately, Legionella bacteria thrive in this environment. Descaling would remove the scale, sediments, and slime present and minimize the development of the bacteria. Disinfecting the area would also ensure that the bacterial growth is stopped.


3. To maintain the safety of homes and businesses.

Hard water scales in boilers, cooling towers and pipework, lowers the efficiency of these parts. In some cases, they might become too dangerous to operate. The scale that develops from calcium and magnesium becomes an insulator between the water and the boiler or pipe’s metal surface, resulting in an increase in the metal’s temperature. Once the scale reaches a certain thickness, the metal overheats and causes blisters in the material to develop. This might eventually lead to equipment to rupture.


4. Lessens energy costs and saves time and money.

Regular descaling results in equipment working at optimal levels. This reduces energy costs that might happen if a boiler or condenser’s heating capacity is compromised, forcing it to work harder. Descaling also reduces the odds of the equipment breaking down, thereby saving time and money needed to fix it

Q: What is the difference between Descaling and Cleaning?

A: All sorts of unwanted impurities can collect in industrial equipment —including bacteria, yeast, and mold. When you clean your equipment, you can effectively remove these impurities. It’s a good idea to clean and disinfect to keep your water  towers  safe and effective.

The purpose of descaling is different. The goal is to remove mineral buildup. Water contains minerals such as calcium, magnesium, and lime. These minerals can build up inside your equipment and in the tubes.  In the worst case scenario, mineral buildup can clog the water flow and prevent your equipment  from working at all. It is highly recommended that descaling is done on water systems regularly.
