UV Water Treatment for Aquaculture in Indonesia

Indonesia's Aquaculture Sector — Water Treatment Context

Indonesia's shrimp aquaculture geography is concentrated in four production regions:

• South Sulawesi (Pinrang, Barru, Bone districts): Indonesia's largest Vannamei production zone — 50,000+ ha shrimp ponds in coastal Sulawesi; intensive and super-intensive production systems; Bugis fishing and aquaculture community; seawater intake from Makassar Strait (UVT 72–84% in open sea, lower near coastal discharge points)
• East Java (Situbondo, Banyuwangi, Pasuruan): Second largest Vannamei zone — coastal ponds along the Java Sea; integrated with seafood processing cluster (PT Bumi Menara Internusa, PT Centralpertiwi Bahari — Indonesia's largest shrimp processors)
• West Java (Indramayu, Karawang, Subang): Proximity to Jakarta export logistics; older ponds transitioning from Black Tiger (Penaeus monodon) to Vannamei; coastal Java Sea intake (UVT 65–76%, lower than Sulawesi due to Java Sea coastal pollution)
• Lampung, Sumatra (PT Dipasena/CP Prima — largest Indonesian shrimp farm, 20,000 ha): CP Prima (Charoen Pokphand Indonesia subsidiary) operates one of the world's largest integrated shrimp farming complexes; semi-intensive to intensive management; Lampung Bay seawater (UVT 72–82%)

FAQ

What is KKP Regulation No. 75/2016 and how does it affect UV use at Indonesian shrimp farms?

KKP (Ministry of Marine Affairs and Fisheries) Regulation No. 75/2016 (Petunjuk Teknis Budidaya Udang — Shrimp Aquaculture Technical Guidelines) sets biosecurity requirements for intensively operated shrimp ponds in Indonesia. Key water treatment provisions: intake water must be treated for pathogen removal before entering ponds; hatchery water must meet biosecure standards; WSSV-positive water must not be introduced to clean ponds. KKP does not specify a technology mandate but accepts UV disinfection at certified doses as the primary intake water treatment method. KKP extension officers (LPPMHP — Fish Health Surveillance Posts) inspect intensive shrimp farms and hatcheries, checking water treatment records. UV system installation documentation and quarterly water quality test results (E. coli, Vibrio plate count) constitute the KKP-acceptable water treatment verification evidence.

Why does Java Sea coastal water have lower UVT than Sulawesi Strait water?

The Java Sea (shallow epicontinental sea between Java and Kalimantan, average depth 46 m) receives significant land-based runoff from Java's dense coastal population (140 million people) and industrial zones — river discharge from Ciliwung, Brantas, and Bengawan Solo rivers carries dissolved organic matter, agricultural runoff, and industrial effluents. Result: Java Sea coastal UVT 62–76% (lower, with more dissolved colour and turbidity from terrestrial input). Makassar Strait (deeper, oceanic water body between Sulawesi and Kalimantan, average depth 1,000+ m) receives less terrestrial input: UVT 78–88% at Sulawesi coastal intake points — better UV operating conditions for South Sulawesi shrimp hatcheries. This explains why Sulawesi shrimp hatcheries can operate UV systems at closer to rated flow capacity than West Java coastal operations, which require more aggressive pre-treatment to bring UVT to 72%+ before UV.

Does CP Prima (Charoen Pokphand Indonesia) use UV water treatment at its Lampung operations?

PT Centralpertiwi Bahari / CP Prima (Indonesia's largest integrated shrimp company — 20,000 ha in Lampung and South Sulawesi, subsidiary of Thailand's CP Foods/Charoen Pokphand) applies CP Foods' global aquaculture quality standards, including CP Foods' Shrimp Biosecurity Protocol. CP's biosecurity standard requires: intake water chlorination-then-dechlorination (backup pathogen control using chlorine + sodium thiosulphate) OR UV treatment at certified dose as the primary intake water disinfection method. For super-intensive ponds at CP Prima Lampung (target 30–50 tonnes/ha/cycle Vannamei production), UV is specified at hatchery intake and at intensive pond water management points. Alpha UV systems are used at CP Prima's integrated operations where zero-chemical intake water treatment aligns with the company's export market (Japan, EU) requirements for drug residue-free shrimp.

What is the UV water treatment specification for a South Sulawesi shrimp hatchery?

A medium-scale South Sulawesi shrimp hatchery (2 million nauplii/day capacity, Pinrang district) with marine water intake from Makassar Strait (25–32 ppt salinity, UVT 78–84% after 25-micron pre-filtration): larval rearing water flow rate 2–5 m³/hour; broodstock tank supply 1–2 m³/hour; total hatchery UV capacity: AU-M 25 at 25 m³/hour rated (derated to 4–6 m³/hour operating flow at 40 mJ/cm² dose — flow rate limited to ensure full dose at hatchery intake UVT). Seawater compatibility: AU-M 25 in 316L stainless steel (not 304 SS — chloride corrosion from seawater will compromise 304 SS housing within 6–12 months in continuous seawater contact). 316L SS housing resists chloride corrosion at 25–32 ppt salinity for the system's rated lifespan (10+ years with standard maintenance).

How does Alpha UV reach remote shrimp farming locations in South Sulawesi?

Air freight to Makassar Sultan Hasanuddin Airport (UPG): 48 hours from India via Singapore or Jakarta hub. Road transport from Makassar to Pinrang (Sulawesi's largest shrimp farming district): 3.5 hours. To Barru: 2.5 hours. To Maros: 1 hour. Indonesia Customs at UPG: AIFTA 0% duty for Indian-origin equipment, VAT 11%, local Makassar customs broker handles PT import documentation. Lamp replacement supply: Alpha UV replacement lamps available from Makassar-based distribution partner or shipped from Jakarta within 3–5 days. 12,000-hour lamp life at 18 hours/day hatchery operation = 22+ months between lamp changes — comparable to annual maintenance schedules at South Sulawesi hatcheries that bring technical support from Makassar annually.
