Troubleshooting your wastewater treatment plant

Overview

All plants are fitted with an alarm, and a buzzer will sound to alert of a fault in the air blower and discharge pump. The buzzer can be muted until the problem is fixed. Once fixed, the alarm will reset automatically and the mute switch must be turned on. All electrical work shall be carried out by a qualified person.

Regular maintenance

Regular maintenance of your product will ensure its longevity. Please see below the different elements that need to be checked regularly:The vent around the blower base. All vents should be checked to make sure they are not blocked or obstructed.

The vent under the desludging cover allows gas to escape and stops the tank from becoming pressurized.

Check if the air blower is working (listen to the “hum”) when you are standing by the plant.

The inlet and outlet should be checked to remove anything that would block the flow.

When do you need to check your wastewater treatment system? At least once per year. An annual maintenance will avoid any bad surprises on your system.

Troubleshooting plant operation

Blower/pump won’t start or run.

Blower operates but delivers no air.

Plant fills above the working water level.

Pump operates but delivers no water.

Blowers runs intermittently.

Pump runs intermittently .

The alarm is sounding, but the pump and blower are working.

Troubleshooting your wastewater treatment plant

Before taking any corrective action, always positively identify the real source of the odour. Check if the odour is coming from another outside source such as a storm drain. All wastewater disposal plants vent gases back through soil pipe and out roof vents. Improperly installed roof vents can cause odour problems. Traps/U-bends in drains prevent odours from entering the home. To function they must contain water and be sealed correctly.

Examples of troubleshooting 

At Tricel we value our customers and we are present from the beginning of the project to the delivery of the product, after the installation and through the years using the Tricel Novo Wastewater Treatment System. 

If you encounter the slightest issue with your Tricel novo, a quick call to Tricel and we are here to help you.

The troubleshooting process is pretty simple. Please find below an example of an intervention provided by a Tricel technician.

Tricel Novo 6PE Wastewater Treatment System in Ballydooneen, Co. Kerry

Our customer called us for troubleshooting on this Tricel Novo, installed 3 years ago. He noticed the alarm coming from his wastewater treatment plant was beeping. A Tricel technician came to his house to fix the problem.

Few seconds after arriving on site, the technician identified the issue: something was going wrong with the compressor. He inspected the plant and observed the lid was surrounded by grass and leaves. The grass was long and cluttered the sides of the lid, preventing the air from entering under the lid and choking the compressor. Consequently, the compressor burned out, and the bacteria were no longer oxygenated. 

The technician changed the compressor in a few minutes and checked the wastewater treatment plant to ensure it was working well. No other issue was found and the plant was properly working.

He informed the owner of the origin of the dysfunctioning of his plant and suggested that he keep the grass around the plant as short as possible. This piece of advice should prevent the owner from changing his new compressor for a long time.

Tricel provides high-standard wastewater treatment plants and relies on years of experience as well as reliable brands. The compressors provided with the Tricel Novo treatment plants are made to keep you years free from troubleshooting unless you don’t follow the guidelines and damage the plant.

Tricel Novo 6PE Wastewater Treatment System in Ballyneety, Co. Limerick

The owner installed a Tricel Novo 6 PE six years ago. Wastewater Treatment Tricel Novo plants ensure compliance with these environmental protection regulations while providing a simple, cost-effective solution.

The tank was full because the blower wasn’t working correctly.

The effluent enters the primary settlement chamber. Settlement occurs when the heavier solids drop out of the wastewater and settle to the bottom of the tank to create sludge, and the lighter solids float to the top of the water to form a scum. The top layer acts as a seal and stops odours from escaping. This chamber separates up to 70% of the solids present. Next is the aeration chamber, where masses of naturally occurring bacteria inhabit specially designed plastic filter media. The bacteria feed on the waste removing it from the liquid. A continuous air supply from a low-pressure, high-volume compressor in the top section of the unit sustains these bacteria. Wastewater passes through the filter media repeatedly, ensuring a very high treatment efficiency. The wastewater then proceeds to the final settlement chamber. Any remaining minute bacterial particles separate from the wastewater within this chamber before discharge from the plant. This process slows the liquid’s velocity, allowing for any final trace impurities to settle into the bottom of the tank. A sludge return system then returns these impurities to the primary settlement chamber.

Here, the solids went to the second and third chambers, which caused the smell around the system.

During the annual maintenance visit, the technician checked the three chambers of the Tricel Novo and changed the compressor to ensure the system worked well. No other issue was found, and the plant was properly working.

Frequently asked questions

FAQs

What is maintenance and servicing?

Part of the servicing can be directly done by yourself. However, the main part of the maintenance and servicing must be done by a professional.

Tricel offers an annual maintenance contract which is a full service every year to guarantee the efficiency of the system gets maintained. For the smooth running of the operation, service personal must get accommodated with unobstructed access to the tank.

Why is maintenance important?

In Ireland, there are approximately 500,000 wastewater treatment systems and most of them are septic tanks. Lack of tank desludging and maintenance of wastewater treatment system is an issue as this poses risks to health or environment.

Is the plant noisy?

There is a slight “hum” from the air compressor when standing close to the plant. When installed correctly, the noise level will not be a nuisance.

Will the plant smell?

There should be no strong odour in the area adjacent to the plant. The presence of a strong odour would indicate that the plant is not working efficiently.

Ventilation must be in place this guarantees a fresh supply of air to the air blower. All vents should be checked to ensure they are not blocked or obscured. Also, investigate if the air blower is still “humming” if not, then this may be causing the issue of replacing the blower as soon as possible to resume the treatment process.

What happens if I get a power cut?

The plant should not be affected by a temporary power outage. After a power cut, checking the plant to ensure it has restarted is essential. It may have an alarm after powering on, but it will fix itself after a few minutes.

In situations where gravity drainage cannot be used, pumped options are available The power outage shouldn’t last too long when you have pump options as power is required to remove the treated liquid. Please do not hesitate to contact us if you have any questions.

How often do I need to empty my sewage treatment plant?

De-sludging is necessary when the sludge occupies 50% of the primary chamber. This is when the sludge is 700mm deep. A licensed company should perform de-sludging intervals every year to prevent sludge buildup. Local councils should have a list of licensed contractors. De-sludging is the responsibility of the homeowner.

For more information, please refer to the 2021 Code of practice Section 12.2.

Is there an alarm in the plant?

An audible and visual alarm is standard and will notify you if there is a problem with the air compressor and discharge pump (pumped plants only), but this does not replace regular inspections. A maintenance agreement is recommended with us to ensure the plant’s optimal performance.

Why is the alarm on my Tricel Novo beeping?

If the alarm is beeping, it may indicate one of the following:

  • The air return pipe to the alarm is not returning an air signal.
  • Electrical fault.
  • The electrical panel is wet.
  • The compressor does not detect enough back pressure from the diffuser (for example, there is not enough water in the middle chamber, or there is damage to the air hose or fitting)
  • The compressor needs maintenance.
  • In all cases, you should call our office or one of our recommended maintenance -companies.
