The One-Bag Process
STEP 01 Batch Tank Add TCN filter aid to your contaminated waste stream. Mix for 10 minutes. 10 min contact time then STEP 02 Pressure Filtration Treated water runs through your pressure filtration system. Contaminant mass removed. Works with most filtration systems result RESULT Compliant Discharge A multi-phase treatment process reduced to two autonomous steps. One product. Works with your system.
The Process in Detail

Two steps that replace
an entire treatment sequence.

The simplicity of the one-bag process is deliberate. The complexity that would otherwise live in your treatment system — the multi-stage chemical additions, the dosing controls, the sequential process steps — has been engineered into the product itself. Your operation sees two steps. The formulation does the rest.

Each TCN filter aid is custom-formulated to the specific contaminant profile of your waste stream. The same two-step process handles soluble metals, fine particle suspensions, and colloidal dispersions — because the active chemistry in the bag is different for each application, even if the process your operators follow is identical.

On Filtration Systems
TCN filter aid is compatible with most industrial pressure filtration systems — if you have filtration infrastructure already in place, it will very likely work with TCN. For facilities starting from scratch, TCN recommends the Oberlin pressure filter as a preferred partner. The Oberlin's automated media cycling — triggered by differential pressure — means the filter self-manages as the filter cake builds, without operator intervention. That autonomy is what makes the two-step process run without specialist oversight.
1
Add TCN filter aid to batch tank

The TCN filter aid — a single bag of custom-formulated product — is added to a batch tank containing your contaminated waste stream. The contents are mixed for ten minutes.

During this contact time, the active chemistry in the filter aid goes to work on your specific contaminants. What happens in the batch tank is specific to your waste stream and your formulation. What you see is ten minutes of mixing.

Run through your pressure filtration system

The treated water is transferred to your pressure filtration system. The filter removes the contaminant mass — now captured on the Rice Hull Ash carrier. TCN filter aid is compatible with most industrial pressure filtration systems.

For facilities starting from scratch, TCN recommends the Oberlin pressure filter. Its automated media cycling — triggered by differential pressure — keeps the filter running without operator intervention as the filter cake builds, making the entire two-step process autonomous.

What This Replaces

Most treatment sequences
have more moving parts
than they need to.

Complex wastewater challenges typically attract complex treatment solutions — multiple chemical addition points, sequential process stages, separate equipment for each step, and the operational overhead to manage all of it. That complexity is often a symptom of solving a chemistry problem with process engineering.

TCN moves the complexity into the product. The result for your facility is a treatment process that is simpler to operate, simpler to troubleshoot, and simpler to maintain — without compromising on what the treatment actually achieves.

Conventional Approach
  • Multiple chemical addition steps
  • Sequential coagulation and flocculation stages
  • Separate dosing systems per chemical
  • pH monitoring and adjustment
  • Complex process controls
  • Specialist operator knowledge required
  • Multiple points of potential failure
TCN Approach
  • One product added to batch tank
  • Ten minutes of mixing
  • Works with your existing filtration system
  • No multi-stage chemical management
  • No specialist operator required
  • Two steps — repeatable every cycle
  • Custom chemistry for your waste stream
Who This Is For

The engineer who has already
tried the standard answers.

Plant Engineers & EHS Managers
You understand the process. You've tried the conventional approaches — standard filter aids, chemical precipitation programs, off-the-shelf coagulants. Something in your waste stream isn't responding. TCN's value is in the formulation: chemistry engineered to your specific contaminants, not a generic product applied to your problem.
Operations Directors & Plant Managers
You need the problem solved without adding operational complexity or specialist dependency. TCN's two-step process is something your existing team can run. There's no multi-phase chemical management system to maintain, no complex controls to monitor, and no new specialist role to staff.
Facilities Under Compliance Pressure
Permit deadlines concentrate the mind. If a discharge inspection result or a compliance deadline is driving urgency, that context is useful — it helps TCN understand the timeline and scope the right solution. Tell us what you're facing and when.
Operations With Complex Waste Streams
Some waste streams don't fit a standard treatment category — multiple contaminant types, unusual process chemistries, difficult particle profiles. TCN's formulation capability has no fixed limit. If the problem can be solved with chemistry and filtration, it's worth a conversation.

Ready to find out if TCN
can solve your specific problem?

The process is the same for every customer. The formulation is never the same twice. Tell us about your waste stream — your contaminants, your process, what you've already tried — and we'll tell you honestly whether TCN can address it.
