Enter your plant's discharge flow and receiving water type to read the Column A / B / C caps for COD, TOC, total nitrogen, total phosphorus, pH, suspended solids and ammonia under Vietnam's QCVN 40:2025/BTNMT. Built from Table 1 (flow-split) and Table 2 (non-flow-split) of the standard — every limit is citable.
In force since 1 Sep 2025 · replaces QCVN 40:2011 · F = discharge flow (m³/day)All limits are mg/L unless noted. Column A / B / C is assigned by the permitting authority; this tool returns the cap for each column.
Five facts every EPC and plant operator should keep next to the permit.

QCVN 40:2025/BTNMT caps COD at ≤65/90/130 mg/L by receiving-water Column A/B/C for discharge flow F ≤ 2,000 m³/day, tightening to ≤60/70/90 mg/L for F > 2,000 m³/day.QCVN 40:2025/BTNMT 按受纳水体 A/B/C 栏对 COD 限值为：排放流量 F ≤ 2,000 m³/天时 ≤65/90/130 mg/L；F > 2,000 m³/天时收紧为 ≤60/70/90 mg/L。QCVN 40:2025/BTNMT membatasi COD pada ≤65/90/130 mg/L menurut Kolom A/B/C perairan penerima untuk debit pembuangan F ≤ 2.000 m³/hari, diperketat menjadi ≤60/70/90 mg/L untuk F > 2.000 m³/hari.QCVN 40:2025/BTNMT giới hạn COD ở mức ≤65/90/130 mg/L theo Cột A/B/C của nước tiếp nhận đối với lưu lượng xả F ≤ 2.000 m³/ngày, siết chặt thành ≤60/70/90 mg/L khi F > 2.000 m³/ngày.QCVN 40:2025/BTNMT กำหนดขีดจำกัด COD ที่ ≤65/90/130 mg/L ตามคอลัมน์ A/B/C ของแหล่งน้ำรับน้ำทิ้งสำหรับอัตราการระบาย F ≤ 2,000 m³/วัน และเข้มงวดขึ้นเป็น ≤60/70/90 mg/L เมื่อ F > 2,000 m³/วันQCVN 40:2025/BTNMT mengehadkan COD pada ≤65/90/130 mg/L mengikut Lajur A/B/C air penerima untuk aliran pelepasan F ≤ 2,000 m³/hari, diketatkan kepada ≤60/70/90 mg/L untuk F > 2,000 m³/hari.Ang QCVN 40:2025/BTNMT ay nagtatakda ng limit ng COD sa ≤65/90/130 mg/L ayon sa Column A/B/C ng tubig na tumatanggap para sa daloy ng pagdiskarga na F ≤ 2,000 m³/araw, na higpitan sa ≤60/70/90 mg/L para sa F > 2,000 m³/araw.
Yes. Organizations may choose either basis. The TOC equivalents are ≤35/50/75 mg/L at F ≤ 2,000 m³/day and ≤25/40/50 mg/L above it.可以。企业可任选任一口径。对应的 TOC 限值为：F ≤ 2,000 m³/天时 ≤35/50/75 mg/L，超过该流量则为 ≤25/40/50 mg/L。Ya. Organisasi dapat memilih salah satu dasar. Ekuivalen TOC adalah ≤35/50/75 mg/L pada F ≤ 2.000 m³/hari dan ≤25/40/50 mg/L di atasnya.Có. Tổ chức được chọn một trong hai cơ sở. Các mức tương đương TOC là ≤35/50/75 mg/L ở F ≤ 2.000 m³/ngày và ≤25/40/50 mg/L khi vượt mức đó.ได้ องค์กรสามารถเลือกใช้วิธีใดวิธีหนึ่งก็ได้ ค่าทดแทน TOC คือ ≤35/50/75 mg/L สำหรับ F ≤ 2,000 m³/วัน และ ≤25/40/50 mg/L เมื่อเกินกว่านั้นYa. Organisasi boleh memilih mana-mana asas. Setara TOC ialah ≤35/50/75 mg/L pada F ≤ 2,000 m³/hari dan ≤25/40/50 mg/L melebihi itu.Oo. Maaaring piliin ng mga organisasyon ang alinmang batayan. Ang mga katumbas na TOC ay ≤35/50/75 mg/L sa F ≤ 2,000 m³/araw at ≤25/40/50 mg/L kapag lampas dito.
No. Only COD, TOC, BOD5 and TSS split at the 2,000 m3/day flow threshold. Ammonia (NH4+-N, ≤5/10/12 mg/L), total nitrogen (20/40/60 mg/L) and pH (6–9) are identical across columns; total phosphorus is split by receiving water (river 4/6/10, lake 2/2.5/3 mg/L), not by flow.不会。只有 COD、TOC、BOD5 和 TSS 在 2,000 m³/天流量阈值处分档。氨氮（NH4+-N，≤5/10/12 mg/L）、总氮（20/40/60 mg/L）和 pH（6–9）各栏一致；总磷按受纳水体分档（河流 4/6/10、湖泊 2/2.5/3 mg/L），而非按流量。Tidak. Hanya COD, TOC, BOD5, dan TSS yang membelah pada ambang debit 2.000 m³/hari. Amonia (NH4+-N, ≤5/10/12 mg/L), total nitrogen (20/40/60 mg/L), dan pH (6–9) identik di semua kolom; total fosfor dibagi menurut air penerima (sungai 4/6/10, danau 2/2,5/3 mg/L), bukan debit.Không. Chỉ COD, TOC, BOD5 và TSS được phân chia tại ngưỡng lưu lượng 2.000 m³/ngày. Amoniac (NH4+-N, ≤5/10/12 mg/L), tổng nitơ (20/40/60 mg/L) và pH (6–9) giống nhau ở mọi cột; tổng photpho phân chia theo nước tiếp nhận (sông 4/6/10, hồ 2/2,5/3 mg/L), không theo lưu lượng.ไม่ มีเพียง COD TOC BOD5 และ TSS เท่านั้นที่แบ่งตามเกณฑ์อัตราการไหล 2,000 m³/วัน อำมอนีม (NH4+-N, ≤5/10/12 mg/L) ไนโตรเจนทั้งหมด (20/40/60 mg/L) และ pH (6–9) เหมือนกันในทุกคอลัมน์ ส่วนฟอสฟอรัสทั้งหมดแบ่งตามแหล่งน้ำรับน้ำทิ้ง (แม่น้ำ 4/6/10 ทะเลสาบ 2/2.5/3 mg/L) ไม่ใช่ตามอัตราการไหลTidak. Hanya COD, TOC, BOD5 dan TSS yang dibahagikan pada ambang aliran 2,000 m³/hari. Amonia (NH4+-N, ≤5/10/12 mg/L), jumlah nitrogen (20/40/60 mg/L) dan pH (6–9) adalah sama di semua lajur; jumlah fosforus dibahagikan mengikut air penerima (sungai 4/6/10, tasik 2/2.5/3 mg/L), bukan aliran.Hindi. Tanging COD, TOC, BOD5, at TSS lamang ang hinati sa 2,000 m³/araw na pangangatwiran ng daloy. Ang ammonia (NH4+-N, ≤5/10/12 mg/L), total nitrogen (20/40/60 mg/L), at pH (6–9) ay magkapareho sa lahat ng column; ang total phosphorus ay hinati ayon sa tubig na tumatanggap (ilog 4/6/10, lawa 2/2.5/3 mg/L), hindi ayon sa daloy.
No. Turbidity (NTU) and suspended solids (mg/L) are different quantities. A turbidity meter cannot prove TSS compliance — TSS must be determined by gravimetric (weight) or optical TSS analysis per the standard.不是。浊度（NTU）与悬浮物（mg/L）是不同量纲。浊度计无法证明 TSS 合规——TSS 必须按标准通过重量法或光学 TSS 分析确定。Tidak. Kekeruhan (NTU) dan padatan tersuspensi (mg/L) adalah kuantitas berbeda. Meter kekeruhan tidak dapat membuktikan kepatuhan TSS — TSS harus ditentukan secara gravimetri (berat) atau analisis TSS optik menurut standar.Không. Độ đục (NTU) và chất rắn lơ lửng (mg/L) là hai đại lượng khác nhau. Máy đo độ đục không thể chứng minh tuân thủ TSS — TSS phải xác định bằng phương pháp trọng lực (cân) hoặc phân tích TSS quang học theo tiêu chuẩn.ไม่ ความขุ่น (NTU) และของแข็งแขวนลอย (mg/L) เป็นปริมาณที่ต่างกัน เครื่องวัดความขุ่นไม่สามารถพิสูจน์การปฏิบัติตาม TSS ได้ — TSS ต้องกำหนดโดยวิธีแกรวิตเทชัน (น้ำหนัก) หรือการวิเคราะห์ TSS เชิงแสงตามมาตรฐานTidak. Kekeruhan (NTU) dan pepejal terampai (mg/L) adalah kuantiti berbeza. Meter kekeruhan tidak dapat membuktikan pematuhan TSS — TSS mesti ditentukan secara gravimetri (berat) atau analisis TSS optik mengikut standard.Hindi. Ang turbidity (NTU) at suspended solids (mg/L) ay magkaibang quantity. Ang turbidity meter ay hindi makapapatunay ng TSS compliance — ang TSS ay dapat matukoy sa pamamagitan ng gravimetric (timbang) o optical TSS analysis ayon sa standard.
