In an era where clean water is becoming an increasingly precious resource, Biosystems Group stands out as a leader in industrial water treatment solutions. Founded in 1996 and headquartered in Bali, Indonesia, BSG has developed over more than 25 years a strong reputation in Southeast Asia for its expertise in designing, building, and operating advanced water and wastewater treatment systems.
Comprehensive Design-Build Expertise
As a design-build water treatment company, Biosystems Group offers end-to-end services to meet diverse industrial needs. From initial feasibility studies and design to procurement, construction, commissioning, and after-sales care, BSG handles the full lifecycle of water treatment infrastructure.
What sets BSG apart is its in-house capability: not only does it manufacture and assemble systems, but it also has internal control-system expertise, allowing highly flexible process implementation.
This ensures customized and optimized solutions that match each client’s operational and water-quality requirements.
Tailored Solutions for Industrial Water Needs
BSG recognizes that “water is a basic requirement for many different types of industries“. To this end, the company has served a broad spectrum of sectors, including:
– Mining, supporting process water systems
– Manufacturing, treating industrial water to meet quality standards
– Hospitality and Resorts, supplying potable or process water
– Municipal, supporting public water supply projects
BSG’s water purification systems include reverse osmosis (RO) plants, available in skid-mounted or containerized configurations. Their standard RO product line ranges from 60,000 US gallons/day (~225 m³/day) up to 400,000 US gallons/day (~1,500 m³/day). There is also a standard “2800 m³/day” train line, designed to be scalable for larger industrial installations.
Particularly noteworthy is their reverse osmosis system for sea water (SWRO), which can handle very high salinity (TDS up to 40,000 mg/L) to produce potable-quality water. For industrial or brackish water sources, BSG offers both high-brackish water (HBRO) and low-brackish (LBRO) RO systems, tailored for the TDS levels of the feed water.
Advanced Wastewater Treatment & ARB Technology
Beyond water purification, Biosystems Group is a specialist in wastewater treatment. They have executed over 200 turnkey wastewater (EPC) and O&M (operation & maintenance) contracts. Their capabilities include in-house design, system integration, fabrication, and rigorous cost control, ensuring high-quality outcomes and long-term reliability.
One of BSG’s core wastewater treatment technologies is the Air Recirculation Bioreactor (ARB), a system adapted to manage complex or challenging waste streams. Their modular, containerized sewage treatment systems add to their flexibility, enabling deployment in diverse settings — from remote sites to densely built urban areas.
Operations, Maintenance & Remote Monitoring
A strong competitive advantage for Biosystems Group is its commitment to after-sales service. BSG offers O&M services under long-term contracts or as needed, providing technical assistance, troubleshooting, and spare parts to clients. Furthermore, many of their plants support internet-based remote monitoring, meaning system performance can be tracked and managed in real time, improving reliability and responsiveness.
Sustainability & Responsible Water Use
BSG’s work also reflects a strong sustainability ethos. By providing systems that reduce waste, maximize water recovery, and efficiently treat high-salinity sources, they help industries minimize environmental impact. Their design-build model ensures that projects are tailored to the client’s site-specific needs — avoiding over-engineering and supporting resource efficiency.
Additionally, Biosystems Group developed a bottling plant solution for hotels and resorts with the goal to minimize single-use plastic bottles. Their bottling system uses ultrafiltration membranes, nanotechnology, and UV treatment to produce pure drinking water that meets WHO standards, packaged in reusable glass bottles.
Proven Track Record & Global Reach
With more than 200 projects completed across EPC and O&M contracts, BSG has built a strong portfolio. Their geographical footprint is broad: not only in Indonesia, but also in other Southeast Asian markets such as the Philippines and Vietnam, as well as in the Solomon Islands, Australia, Papua New Guinea, and Nigeria.
BSG is also recognized by major international institutions — it is an accredited supplier for organizations like the World Bank, United Nations, and the Australian Department of Foreign Affairs and Trade (DFAT).
