Saat ini kami sedang melakukan proses fabrikasi untuk proyek Water Treatment Plant (WTP) 200 M3/Day bagi salah satu customer kami di Sidoarjo.

Sistem ini terdiri dari rangkaian proses:
Sand Filter → Carbon Filter → Softener → Reverse Osmosis

Targetnya adalah menghasilkan air dengan TDS rendah dan bebas bakteri untuk mendukung proses produksi industri makanan.

Seluruh proses fabrikasi kami kerjakan secara mandiri di workshop, mulai dari:
✅ FRP Raw Water Tank & Brine Tank
✅ Pressure Vessel
✅ Reverse Osmosis (RO) Skid

Seluruh pekerjaan fabrikasi dikerjakan oleh certified welder dan tim engineering kami.

Bagi kami, fabrikasi internal bukan hanya tentang cost reduction, tetapi juga tentang memiliki kontrol penuh terhadap kualitas, engineering, dan fleksibilitas desain. Setiap proyek memiliki tantangan yang berbeda karena setiap customer memiliki kebutuhan yang unik.

Itulah alasan mengapa kami membangun kemampuan fabrikasi secara mandiri—agar setiap solusi yang kami berikan benar-benar sesuai dengan kebutuhan pelanggan.

Back in 2015, PT. Tirta Semesta Engineering designed and installed a 200 m³/day Membrane Bioreactor (MBR) Wastewater Treatment Plant for a beverage contract manufacturing company in Gresik, East Java, Indonesia.

𝗔𝗳𝘁𝗲𝗿 𝗺𝗼𝗿𝗲 𝘁𝗵𝗮𝗻 𝟭𝟬 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗿𝗲𝗹𝗶𝗮𝗯𝗹𝗲 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻, the system continues to perform as intended. This reflects the importance of proper engineering, quality fabrication, and the right technology in delivering long-term operational reliability.

As part of our lifecycle support services, our team recently carried out a major refurbishment, including:

✔️ Replacement of the MBR sheet membranes

✔️ Repair and restoration of the MBR tank body

This refurbishment helps restore the system's performance, extend its service life, and ensure continued operational efficiency for years to come.

At PT. Tirta Semesta Engineering, our commitment doesn't end with commissioning. We continue to support our customers through maintenance, refurbishment, retrofitting, and technical services, ensuring every water and wastewater treatment system operates at its best throughout its lifecycle.

Hubungan safety dengan keberlajutan usaha….

Keselamatan kerja (safety) memiliki hubungan yang sangat erat dengan keberlanjutan usaha (business sustainability).

Perusahaan yang memiliki budaya keselamatan yang baik cenderung lebih stabil, efisien, dipercaya pelanggan, dan mampu bertahan dalam jangka panjang.

Safety bukan hanya tentang mencegah kecelakaan, tetapi juga melindungi:

* sumber daya manusia,
* aset perusahaan,
* operasional,
* reputasi perusahaan,
* dan keberlangsungan bisnis itu sendiri.
