A digester with indigestion. Funny?

Digester cleaning to revive your plant performance.

Clean my digester

Don’t let waste, waste your digester.

Over time, debris such as gravel, sand, plastics, grease, and scum will accumulate in your digester. This buildup can reduce the effective tank volume by over 50%, decreasing the available retention time and making your digester less effective. It also negatively impacts heat exchangers, pipes, and pumps by increasing wear and tear and by plugging them with rags, which prevents proper operation. Regular cleaning removes these issues, ensuring your digester operates at peak performance.

Signs your digester needs cleaning.

Don’t wait for processing efficiency to drop; we recommend cleaning your digester every four years. This provides an excellent opportunity to inspect your entire system for any issues. Our experienced team is here to help you maintain your digester and ensure that your wastewater treatment process runs smoothly.

Big indicators

Some larger indicators that a cleaning is urgently needed:

  • Heat exchanger pluggingIf the heat exchangers are clogged, it can hinder the heat transfer necessary for maintaining optimal temperatures in the digester. This can lead to temperature fluctuations and affect microbial activity.
  • Pipe or pump pluggingBlockages in the pipes can lead to reduced flow rates, increased pressure, and potential system failures.
  • Poor mixingVisible layers or inadequate mixing can suggest issues, but the severity may vary.
  • Increased retention timeLonger retention times without increased biogas production indicate inefficiency.
  • Frequent maintenance on auxiliary equipmentf auxiliary equipment (like pumps, mixers, or heat exchangers) requires frequent maintenance or repairs, it may indicate that the system is not operating optimally and could benefit from cleaning.

Small indicators

Smaller indicators that something maybe off:

  • Odor issuesStrong, unpleasant odors (ammonia or hydrogen sulfide) indicate poor breakdown of organic material.
  • Low biogas productionA significant drop in biogas production compared to normal levels.
  • High volatile fatty acidsElevated VFAs indicate an imbalance in the digestion process.
  • pH imbalancepH levels outside the optimal range (6.8 to 8.0) can inhibit microbial activity.
  • Increased solids contentA buildup of solids can reduce efficiency and hydraulic retention time.

Effective management of each project.

The proper process to improve your processing.

  • Evaluation and safety

    Conduct a detailed evaluation of the site to identify project specific needs. This evaluation ensures a tailored approach to the cleaning of the digester, prioritizing safety and efficiency while taking all operational constraints into account.

  • Tank preparation

    Set up the necessary equipment, isolate the digester, and pump out the remaining liquid to provide access for the cleaning equipment. This facilitates smooth operations while ensuring safety is not compromised.

  • Removal of solids

    Use vacuum trucks, pumps, and screening and dewatering equipment to remove the accumulated sludge and solids. This process efficiently clears the digester, preparing it for the subsequent steps in the process.

  • Cleaning and inspection

    Clean the interior of the digester and conduct a visual inspection to identify and report any potential issues, ensuring that all surfaces are free from debris.

From grit to great.

We thoroughly clean your digester. Removing the hair, grease, grit, gravel, and other debris built up in your tank. Our team is equipped to remove all types of debris and comes with tools tailored to suit your project, including pumping, vacuuming, pressure washing, pipe flushing, and dewatering equipment. We use these tools to ensure a comprehensive cleaning of your digester from top to bottom. Our team is trained and ready to handle every aspect of the cleaning process, getting your digester back to you as quickly as possible.

Dual VAC

Two times fasterWessuc’s dual-vacuum system provides the ability to maintain continuous suction throughout the duration of a job. This unique system cuts in half the time it takes to clean large tanks. Allowing us to return the tank back to the client as quickly as possible.

Screening

Full trash canThe physical screening of digester sludge removes the large hair balls, rags and plastics that can build up in a tank. If the material is being reused on agricultural land this provides the farmer with confidence that his land is being used responsibly.

Confined spaces

Do not enterConfined spaces pose many risks that could potentially harm or kill an entrant. These risks must be evaluated and minimized through proper safe guards. Wessuc plans for safety at the outset of each project, which enables us to react quickly to any circumstances that may arise during a clean out project.
