These kits are built for koi and landscape ponds where space is tight. Exact footprints and ports vary by kit; the common baseline is below—confirm details at order to match your pit.
Process: Drum (~60–74 µm) → Bio (media bed) → ports for UV/ozone.
Controller: dual backwash triggers (level + time).
Assembly: ships pre-assembled / pre-wired; connect water & power on site.
Flow lane: 5–20 m³/h documented for compact koi/small-room upgrades.
Interfaces: standard I/O stubs plus backwash discharge, reserved ports for UV/ozone.
Tip: keep UV exposure time in step with the drum’s backwash cadence and your actual line flow—small systems feel that coupling fast.

Materials & interfaces your installer will ask about
Wet-end housings: PP/UPVC across this size class for freshwater, brackish, and marine installs.
Plumbing baselines: ED-30 Ø110 mm, ED-60 Ø160 mm—set manifolds/valves to those sizes; leave tees for UV/ozone/backwash.
Controls (optional): multi-language UI, RS485/MODBUS, UV fault alarms, preset backwash schedules.
What ships with the crate
Pre-assembled
You get clear water without hovering over the system. The drum pulls fines at about 60–74 µm, the bio stage converts ammonia and nitrite steadily, and you’ve got reserved ports for UV/ozone when you want that extra polish. The controller runs level + time backwash so the screen stays open and flow doesn’t choke.
Drop-in install. It arrives pre-assembled / pre-wired. Hook up water and power; no puzzle of elbows and unions.
Small pit, real throughput. The chassis is compact, with access hatches / inspection windows / drains that make weekly care a two-minute job.
Clean hand-offs. Standard I/O sizes and a dedicated backwash discharge keep the plumbing tidy. UV/ozone stubs are ready now—or later.
Hands-off cleaning. Dual-trigger backwash (level + time) keeps the drum mesh clear between services.
Predictable biology. Media bed runs calmly; fewer load swings hit the pond because solids aren’t circling back.
Upgrade-friendly. Add UV for the final barrier, or wire in ozone with an ORP probe when you’re chasing that extra clarity.
Docs in the crate. Manuals, warranty, and inspection/material certificates make acceptance fast if you’re doing this for a client.
Backyard koi / compact bays: choose 5–20 m³/h kits (drum → bio; UV/ozone optional).
Larger landscape runs: step up to 30 / 60 m³/h lines that mirror our farm layouts (drum ≈74 µm, bio, plus UV pairing).
Flow stays stable because the drum unloads fines before the bio stage ever sees them.
No “Franken-plumbing.” The ports and drains match across the module line, so add-ons don’t turn into rebuilds.
QA is baked in. Each powered device is factory-tested (pressure/flow, 24-hour sealing, UV/heat/salt-spray aging) and ships with ISO/CE/RoHS/IP refs.
Show ponds and courtyards that need near-invisible maintenance.
Retrofits where the filter bay is tight and downtime has to be short.
Client installs that need clean handover paperwork and a predictable service routine.
Ignoring backwash cadence—set level + time from day one so UV (if installed) keeps its exposure window.
Sending backwash to the pond—route the backwash discharge
A pond-ready unit that’s already pre-assembled / pre-wired, plus the paperwork installers and clients actually ask for: ISO 9001 / CE / RoHS / IP references, certificate of conformity, packing list, factory test report, user manual, and warranty card. If you need it shipped as a set, container delivery is available.
How we verify before it leaves the floor Each powered device goes through pressure/flow checks, 24-hour sealing, and accelerated aging (UV / heat / salt-spray), then electrical/functional tests. You’re commissioning known-good gear, not troubleshooting a mystery box.
Support that actually helps Remote guidance for install/commissioning is standard; for bigger yard projects, we can dispatch an engineer. Documentation (manuals, wiring, maintenance notes) ships with the crate so acceptance on your side stays quick.
OEM/ODM without friction Branding and cosmetics are easy, but we also customize the brains: multi-language UIs/labels, RS485/MODBUS, UV fault alarms, and preset backwash schedules. Power standards are global—110 / 220 / 380 V, 50/60 Hz.
Timelines you can plan around We track from requirements → drawings → prototype → mass production → packaging → shipment → install guidance → after-sales. Typical modular lead time: 15–25 working days. Sea/LCL/air/express all supported with the usual customs docs.
Quick acceptance checklist (steal this):
Factory test report attached ✅
ISO/CE/RoHS/IP refs in the pack ✅
Manuals / wiring / maintenance docs present ✅
Remote install slot confirmed (or on-site visit if needed) ✅
Plumb the line so water hits the drum (~60–74 µm) first, then the bio stage, and keep the reserved ports for UV / ozone on the clean side. The controller’s level + time backwash keeps the screen open so flow and biology stay steady. Ships pre-assembled / pre-wired, so you’re really just doing water + power.
Plumbing: use the kit’s standard inlet/outlet stubs; route the backwash discharge to waste (don’t loop it back to the pond). Leave tees for later UV/ozone.
Power: connect per nameplate; the control box arrives wired.
Controls: enable dual triggers (level + time) on the drum so fouling doesn’t sneak up between services.
Fill & vent the filter bay; confirm no bypass around the drum chamber.
Dial the design flow for your kit (pond lane 5–20 m³/h; larger sets as specced).
Backwash setup: start with short time-based cycles; keep level trigger armed to catch load spikes. Send discharge to waste.
Bio online: confirm even circulation through the media bed (no dead corners).
Add-ons (if installed): – UV: log lamp hours on day one; plan swaps around ≈9,000 h and keep sleeves clean for stable dose.
–
Ozone:
wire the ORP probe and hold around
~300 mV
in freshwater; make sure off-gas goes to a safe vent.
Drum: quick glance at the screen; verify level + time backwash is cycling.
Bio: lift the hatch; check flow is uniform and the bed isn’t channeling.
Housekeeping: crack the drain for a short purge; keep inspection windows clear so you can see what’s happening inside.
Water still hazy? Confirm dual-trigger backwash is ON and the discharge isn’t returning to the pond.
Flow drops after a day or two? Shorten the time interval and rely more on the level trigger for busy periods.
UV under-delivering (if fitted)? Clean sleeves and check lamp hours toward ~9,000 h; dose lives and dies on sleeve clarity and exposure time.
Chasing that extra polish? Add ozone with ORP control (~300 mV) or bolt on a degassing tower on the return to push CO₂ down.
Two lanes: compact 5–20 m³/h kits for koi/landscape pits, and larger sets built around 30 / 60 m³/h layouts drawn from our farm playbook.
Q2) What’s the process order inside the system? Drum (~60–74 µm) → Bio → (ports for) UV / ozone → return to pond. The controller runs level + time backwash on the drum so screens don’t clog between services.
Q3) Do I need to plumb anything special for backwash? Yes—route a dedicated backwash discharge to waste. Don’t loop it back to the pond. Stub-outs for UV/ozone are already reserved to keep add-ons clean.
Q4) What mesh size is the drum? Catalog standard is about 74 µm on box-type drums; that’s the baseline we use to keep fines off the bio stage and hold UV dose steady.
Q5) How big are the pipe connections if I step up to 30/60 m³/h? ED-30: Ø110 mm I/O. ED-60: Ø160 mm I/O. Build manifolds around those sizes to avoid reducer chains.
Q6) Is it really pre-assembled? What lands with the crate? Yes—pre-assembled / pre-wired. You also get manuals, warranty, and acceptance docs (inspection/material certificates). Container delivery is available when you need sets staged.
Q7) What materials are used—okay for outdoor pits and brackish water? Wet ends in this class use PP/UPVC for corrosion resistance across freshwater, brackish, and marine installs.
Q8) If I add UV later, what should I plan for? UV runs at 254 nm. Design dose is intensity × time; go ~15 mJ/cm² as a floor (avoid photoreactivation) and ~250 mJ/cm² for tougher targets like IPNV. Lamp life is ≈9,000 h—log hours from day one.
Q9) Can I add ozone? How do I control it? Yes—small sets typically use 5–20 g/h generators. Use an ORP probe and hold around ~300 mV in freshwater; make sure off-gas is safely vented.
Q10) I’m chasing clarity and low CO₂. Anything else to add? A degassing tower on the return line is the go-to; catalog sizes map to 30–300 m³/h if you scale up later.
Q11) What about controls—can this talk to my pond cabinet? Yes—OEM/ODM supports multi-language UIs/labels, RS485/MODBUS, UV fault alarms, and preset backwash schedules.
Q12) How do you prove quality before shipping? Powered gear runs pressure/flow, 24-hour sealing, and 72-hour UV/heat/salt-spray aging; exports include ISO 9001 / CE / RoHS / IP references with the manual and warranty card.
Quick picker (pond size → baseline):
Compact koi pits → 5–20 m³/h kit (drum → bio; ports for UV/ozone).
Bigger yards or light farm use → 30 / 60 m³/h with ED-30/ED-60 baselines (Ø110 / Ø160 mm
