drum microfilter (≈60–74 µm), biofilter, protein skimmer, and UV sterilizer into a single package so solids, organics, and pathogens are handled in order—then water heads back clean. Piping and electrics are pre-installed at the factory; on site you hook up water and power and hit go.
It’s built for tight rooms and fast retrofits. The integrated frame saves floor space, ships pre-assembled, and comes with access points, drains, and docs so acceptance is painless. If you’ve got limited manpower or can’t afford a long shutdown, this is the point-solution that lands in one lift and starts earning its keep.
Sizing spans two sweet spots from the playbook:
Mini/pond scale: integrated drum units popular for small RAS and koi upgrades, typically 5–20 m³/h and often bundled with UV and a small biochemical compartment. Commissioning is quick, but coordinate backwash vs. UV exposure so neither step underperforms.
Farm lines: 30 m³/h and 60 m³/h examples pair a box-type drum (74 µm) with matched UV, protein skimmer, and biofilter—a clean template when you want spec-driven gear that already fits together.
What each piece does in the stack:
Drum knocks down fines so the rest isn’t fighting dirt.
Biofilter runs the K5-style media to convert ammonia/nitrite to nitrate.
Protein skimmer strips dissolved organics; it shines in brackish/marine water and usually sits after bio, before UV.
UV at 254 nm is the final barrier; dose is real math (mJ/cm²), with ~15 mJ/cm² as the floor and ~250 mJ/cm² for tough viruses like IPNV. Lamp life is about 9,000 h.
What this “mini RAS block” actually includes A ready-to-plumb package with a drum microfilter (≈60–74 µm), a biofilter (K5-style media), a protein skimmer, and a UV sterilizer—pre-piped and pre-wired. Water hits solids removal first, then bio, then skimming for dissolved organics, and finally UV at 254 nm before returning to tanks. The flow path is deliberate so each step makes the next one’s job easier.
Two size lanes to cover most needs
Compact/pond lane (5–20 m³/h): integrated drum units with built-in UV and optional biochemical media. These are the “land it, plug it, run it” kits for koi and small RAS rooms. Just mind the golden rule: backwash timing has to match your UV exposure time and line flow.
Workhorse lane (30 & 60 m³/h): box-type drum at 74 µm plus matched UV, protein skimmer, and biofilter—with pipe sizes and footprints already laid out for the pair.
What each stage is doing (without the fluff)
Drum microfilter: grabs fines at ~74 µm; box-type ED-PP units publish flows and pipe diameters (e.g., ED-30 uses Ø110 mm, ED-60 uses Ø160 mm). Dual-control backwash (time / level) keeps mesh clean.
Biofilter: K5-method media converts ammonia → nitrite → nitrate; sizes like Ø1500×H2300 mm (30 m³/h) and Ø2300×H2500 mm (60 m³/h) are documented.
Protein skimmer: counter-current microbubbles strip DOC; strongest in brackish/marine; positioned after bio and before UV. Spec examples: EP-S-30 (inlet 50 mm / outlet 75 mm, pump 0.75 kW, Ø800×H2700 mm) and EP-S-60 (inlet 110 mm / outlet 160 mm, Ø900×H2800 mm).
UV sterilizer: 254 nm, dose is intensity × time; design yardsticks: ≈15 mJ/cm² to avoid photoreactivation and ≈250 mJ/cm² for stubborn targets like IPNV. Typical pairings: 3×80 W at 30 m³/h or 6×120 W at 60 m³/h; lamp life ≈ 9,000 h.
Controls and monitoring, if you want it smart The block can talk to a PLC and a small sensor pack—DO, pH, temperature, conductivity; add ORP if you run ozone. Data goes to the cabinet for alarms and simple closed-loop tweaks.
Add-ons that play well with the mini block
Ozone (especially with the skimmer): target ~300 mV ORP in freshwater; keep residuals in check. Typical small-system outputs are 5–20 g/h.
Degassing tower: standard sizes mapped to 30–300 m³/h lines when you need CO₂ off-gas and O₂ pick-up.
Why the all-in-one matters in the real world Pre-assembly saves floor space and install time; the unit shows up factory-wired and plumbed with access hatches, drains, and the usual handover docs (inspection reports, material certs). If your site is tight or you’re racing the clock, this is how you get a functioning loop with one lift and a short commissioning window.
All-in-One Mini RAS — Standard Configurations
| Line Flow | Drum Filter (mesh) | Drum I/O | Backwash | Biofilter (media & size) | Protein Skimmer (model / I/O / pump) | UV Sterilizer (lamps @254 nm) | Lamp Life | Notes |
|---|---|---|---|---|---|---|---|---|
| 30 m³/h | Box-type ED-30 (≈74 µm) | Ø110 / Ø110 mm | Time + level dual control | K5-style media, Ø1500×H2300 mm | EP-S-30 · in Ø50 / out Ø75 mm, pump 0.75 kW, Ø800×H2700 mm | 3 × 80 W (typical pairing) | ≈9,000 h | Pre-piped, pre-wired package; align UV exposure with line flow/backwash. |
| 60 m³/h | Box-type ED-60 (≈74 µm) | Ø160 / Ø160 mm | Time + level dual control | K5-style media, Ø2300×H2500 mm | EP-S-60 · in Ø110 / out Ø160 mm, Ø900×H2800 mm | 6 × 120 W (typical pairing) | ≈9,000 h |
Mini/pond lane (5–20 m³/h): integrated drum units with built-in UV and optional biochemical media are documented as a compact kit; use the same “UV exposure ↔ backwash timing ↔ line flow” rule when commissioning. (Specs vary by kit—confirm at order.)
Pipe standards: box-type drums publish I/O sizes by model (ED-30 Ø110 mm, ED-60 Ø160 mm). Skimmer lines and drains are listed per model above. UV housings pair with the line’s rated flow; EUV-class units in this range are specced at 220 V supply.
Mesh & fouling control: drums run around 74 µm and backwash via time/level triggers to keep the screen clean and UV dose stable.
Housings: PP/UPVC on wet ends across this size class; anti-corrosion choices match freshwater, brackish, and marine setups in the catalog.
Add a small PLC panel with DO, pH, temp, conductivity; include ORP if you run ozone so you can hold around ~300 mV in freshwater systems.
Ozone generator: typical small-system outputs 5–20 g/h; tie ORP to the PLC.
Degassing tower: catalog sizes map to 30–300 m³/h lines to strip CO₂ and stabilize O₂.
Factory pre-assembled block, inspection/material certificates, and the usual handover docs (manuals, wiring, maintenance notes). That’s how you get a fast sign-off and a short commissioning window.
One block, four jobs done right Solids, bio, organics, pathogens—handled in that order. The drum sits around 60–74 µm, the biofilter runs K5-style media, the skimmer strips DOC, and UV at 254 nm cleans up before water returns. The stack is pre-piped so each step feeds the next without guesswork.
Lands fast, runs fast Factory pre-assembled and pre-wired means you’re basically hooking up water and power. That shortens the “dead time” on site and keeps small teams moving. Acceptance is easier too—inspection/material certificates and manuals ride with the crate.
Sized for real rooms, not drawings Two lanes cover the common cases: 5–20 m³/h kits for koi/small RAS, and 30/60 m³/h blocks for farm lines. Pipe diameters, footprints, and pairings are already mapped, so layout tweaks stay minimal.
Operator logic baked in
Drum backwash runs on time/level triggers, keeping the mesh clear and UV dose steady.
Skimmer after bio, before UV—so microbubbles chase DOC upstream of disinfection.
UV dose you can defend: design around ≈15 mJ/cm² as the floor; go to ≈250 mJ/cm² for stubborn viruses like IPNV. Lamp life sits around 9,000 h.
Space saver without the “Franken-plumbing” The integrated frame cuts footprint and eliminates the spaghetti of separate skids, elbows, and supports. That’s why these mini blocks are the go-to in tight rooms and backyard upgrades.
Plays nicely with the bigger system Need ozone or degassing? Bolt them on using the same interfaces we ship across the modular RAS line. Target ~300 mV ORP for freshwater ozone work; use a degassing tower when CO₂ creeps up. Sensors and a small PLC panel tie it all together.
Commissioning that doesn’t bite you later The one rule: sync drum backwash with actual line flow and UV exposure time. Do that on day one and you won’t be chasing dose dips or dirty screens a week later.
Quick win checklist (save for the SOP)
Drum mesh around 74 µm confirmed
Bio media loaded and aeration set
Skimmer plumbed between bio → UV
UV lamps logged (start hours → plan for ~9,000 h)
If ozone used: ORP probe online, setpoint ~300 mV
It arrives ready to pass inspection You get the paperwork buyers actually ask for: ISO 9001 / CE / RoHS/IP references, certificate of conformity, packing list, factory test report, user manual, warranty card—packed export-grade so it shows up clean and undamaged.
We test it before you ever power it up Each unit runs a multi-step QA: pressure/flow checks, 24-hour sealing on closed bodies, accelerated aging (UV/heat/salt-spray), and full functional tests on controls/valves. You’re commissioning known-good hardware, not debugging a science project.
Support that actually picks up Baseline warranty is 12 months on the device, with remote diagnostics/upgrades on control systems and lifetime technical consulting for ops. Need a human? 7×12-hour bilingual (EN/ZH) support for sizing, drawings, remote commissioning, troubleshooting, and CAD calls; on larger jobs we can send an engineer.
OEM/ODM without friction Multi-language UIs, global voltages (110/220/380; 50/60 Hz), region-specific pipe interfaces, color/material options, and CAD/3D pre-approval so your team signs off before production. Need to bid? We prep the spec pack—certs, drawings, and cost estimates.
Lead times you can plan around Tracked workflow from requirements → drawings → prototype → mass production → packaging → shipment → install guidance → after-sales. Modular systems typically land in 15–25 working days. Containerized/LCL/air/express are all supported, with the standard customs docs.
Handover docs ride with the crate Factory-pre-assembled block plus inspection/material certificates, manuals, wiring, and maintenance notes—so acceptance on your side is quick.
Acceptance checklist (steal this):
Factory test report attached ✅
ISO/CE/RoHS/IP refs in the pack ✅
Manuals + wiring + maintenance guide ✅
Spare parts list + install videos/remote slot scheduled ✅
Q1) What flows does this mini all-in-one cover? Two lanes: 5–20 m³/h compact kits for ponds/small rooms, and 30 / 60 m³/h integrated blocks for farm lines.
Q2) What’s the correct process order inside the block? Drum (≈74 µm) → Biofilter (K5-style media) → Protein skimmer → UV (254 nm), then back to tanks. That order keeps each step from fighting the next one.
Q3) How do I size the plumbing? The box-type drum publishes I/O diameters: ED-30 uses Ø110 mm, ED-60 uses Ø160 mm. Build your manifolds around those baselines.
Q4) What mesh and backwash should I expect on the drum? Standard mesh is around 74 µm with dual backwash triggers (time + level) to keep the screen clean between services.
Q5) Where exactly does the skimmer sit—and why? After bio, before UV. Microbubbles strip DOC so the UV doesn’t waste dose on organics. (Models like EP-S-30/60 are documented with their I/O and dimensions.)
Q6) What UV dose and lamp life should I plan for? Design around ≈15 mJ/cm² as the floor (avoid photoreactivation) and go to ≈250 mJ/cm² for tougher targets like IPNV. Lamp life is ≈9,000 h; log hours from day one.
Q7) Can I add ozone or a degassing tower later? Yes. Target ~300 mV ORP in freshwater when ozonating (small systems: 5–20 g/h outputs). Degassing towers in the catalog map to 30–300 m³/h lines for CO₂ control.
Q8) What sensors/controls can this block talk to? A compact PLC panel with DO, pH, temperature, conductivity is standard fare; add ORP if you run ozone.
Q9) How is it delivered—do I have to assemble on site? It ships factory pre-assembled with inspection/material certificates, manuals, wiring, and maintenance notes. That’s how you keep acceptance short.
Q10) Is it suitable for koi and backyard ponds? Yes—the 5–20 m³/h integrated kits are made for compact spaces and quick installs.
Q11) What power standards can you build for? Global voltages and frequencies—110/220/380 V, 50/60 Hz—are supported under OEM/ODM.
Q12) Any gotchas during commissioning? Sync drum backwash timing with actual line flow and UV exposure time so you don’t under-dose or overload the screen. It’s the #1 thing that separates smooth starts from problem weeks.
Quick picker (flow → baseline drum I/O): 30 m³/h → ED-30 → Ø110 mm 60 m³/h → ED-60 → Ø160 mm
Where this block sits (and why it works there) Plumb the mini RAS so water hits the drum first (≈60–74 µm), rolls into the biofilter, then through the protein skimmer, and finishes at UV 254 nm before returning to tanks. That order keeps each step doing the job it’s best at—solids off the screen, TAN handled in bio, DOC skimmed, then the disinfection pass.
Flow pairing: choose the 30 m³/h or 60 m³/h stack (or the 5–20 m³/h kit for ponds) so the block matches your recirculation rate.
Pipe sizes (drum): ED-30 uses Ø110 mm I/O; ED-60 uses Ø160 mm—set manifolds and valves to those baselines.
Backwash services: connect the drum backwash drain to a safe discharge. Enable time + level triggers in the controller.
Power & panel: confirm regional supply (110/220/380; 50/60 Hz) on the nameplate and the control cabinet wiring.
Add-ons ready? If you’re adding ozone or a degassing tower, leave tees and isolation valves in place now—don’t retrofit later.
Fill & vent the block; check there’s no bypass around the drum chamber.
Set design flow (30 / 60 m³/h or 5–20 m³/h kit). Verify stable level in the drum’s clean side.
Backwash calibration: start conservative time-based cycles; enable level-trigger to catch spikes. Confirm the backwash discharge path.
Biofilter online: charge the K5-style media with aeration and confirm even circulation.
Skimmer tune: open air and water valves until you see a stable, dry foam head; the skimmer sits after bio, before UV.
UV enable: log lamp hours at zero and verify intensity read-backs; plan replacement around ≈9,000 h.
Golden rule: sync the drum backwash timing with actual line flow and UV exposure time—that’s how you avoid dose dips and dirty screens later.
Drum screen: check for fouling; keep time + level backwash active so mesh stays near-clean.
Biofilter: verify media motion and aeration; note any channeling that hints at flow imbalance. (K5-method media is the baseline.)
Skimmer: empty the cup, confirm stable foam; adjust air if the head gets watery after feedings.
UV: wipe sleeves on schedule; track the lamp-hour counter toward ~9,000 h.
Wire a compact PLC with DO, pH, temperature, conductivity; add ORP when running ozone, targeting around ~300 mV in freshwater systems. Use alarms to catch backwash faults and UV trips early.
Under-dose on UV? Clean sleeves, confirm flow is at spec, and check that backwash events aren’t stealing exposure time.
Dirty water post-drum? Verify 74 µm mesh and that level-trigger backwash is live.
Foam collapse in skimmer? Re-balance air/water; check salinity if you’re in brackish/marine mode.
CO₂ creeping up or fish at surface? Add / upsize the degassing tower on the return.
ORP drifting when ozonating? Calibrate probe and keep the setpoint near ~300 mV; review off-gas handling.
The block arrives factory pre-assembled with inspection/material certificates, manuals, wiring, and maintenance notes, which shortens acceptance and commissioning on your side.
