In the modern industrial ecosystem, water is not merely a supporting utility; it is a vital resource whose cycle must be managed with high precision. With tightening government oversight through the Ministry of Environment and Forestry (KLHK), liquid waste management can no longer be viewed solely as a “cost burden.” Instead, it is a strategic investment for business sustainability.
Many industrial players find themselves trapped in serious legal issues due to negligence in managing their factory effluent. The risks of factory sealing, billions of Rupiah in fines, and even the revocation of operational permits are real threats for companies failing to meet Environmental Quality Standards (Baku Mutu Lingkungan). In Indonesia, the PROPER (Company Performance Rating Program in Environmental Management) assessment has become the benchmark for corporate reputation in the eyes of the public and investors. A “Red” or “Black” grade on a PROPER report can destroy a company’s image in an instant.
Therefore, selecting a partner for Industrial Wastewater Treatment Plant (WWTP) Installation Services is a crucial decision. A WWTP (or IPAL in Indonesian) is not just a holding pond for dirty water. It is a complex biological and chemical engineering system designed to neutralize hazardous pollutants before the water is returned to nature or reused (water recycle).
PT Mizui Osmosa Teknovasi is here as your strategic partner. We are not just contractors; we position ourselves as an engineering partner who understands that every drop of waste has unique characteristics. With years of experience handling the complexities of liquid waste—ranging from the Food & Beverage industry and textiles to heavy manufacturing—we ensure your WWTP installation is not only structurally sound but also operates efficiently, stably, and in full compliance with applicable regulations.
Understanding Regulations & Key Parameters: Why “One Design Fits All” is Impossible
As an environmental engineer, I often encounter factory owners who ask, “Can I copy-paste the WWTP design from the factory next door?” The answer is a firm No.
Every industry produces a different pollutant footprint. Liquid waste from the textile industry, rich in synthetic dyes and heavy metals, requires significantly different handling compared to waste from a slaughterhouse, which is laden with fats and blood. Fatal errors in determining treatment technology begin with a failure to understand the waste characteristics (influent) and the target quality standards (effluent).
The Indonesian government has established strict standards through various regulations, with the primary reference being Minister of Environment and Forestry Regulation No. 5 of 2014 concerning Wastewater Quality Standards. Within this regulation, several key parameters must be controlled:
Biological Oxygen Demand (BOD): Measures the amount of oxygen required by bacteria to decompose organic matter. High BOD figures indicate water is heavily polluted with organics.
Chemical Oxygen Demand (COD): Measures the amount of oxygen needed to chemically decompose all organic matter (both biodegradable and non-biodegradable). This is often the hardest parameter to lower in chemical industries.
Total Suspended Solids (TSS): Suspended solids that cause water turbidity.
Acidity (pH): Wastewater must be neutral (pH 6-9) before discharge to avoid damaging river ecosystems.
Ammonia & Nutrients: Crucial parameters for fertilizer or food processing industries. Excess levels can cause eutrophication (algae blooms) in receiving water bodies.
At PT Mizui Osmosa Teknovasi, we never guess. The first step in our WWTP installation service always begins with sampling and comprehensive laboratory analysis. We design systems based on your specific pollutant load, ensuring that the resulting output is always below the thresholds set by the government. Compliance is non-negotiable.
Treatment Technology: Evolution from Conventional to Advanced Treatment
The core of a liquid waste treatment system is the ability to separate pollutants from pure water. Broadly, this approach is divided into Physical, Chemical, and Biological processes. However, the “heart” of most industrial WWTPs is the Biological process, where we utilize microorganisms to consume these pollutants.
1. Aerobic vs. Anaerobic WWTP Design
A deep understanding of aerobic and anaerobic WWTP design is essential for energy and land efficiency.
Anaerobic System (Without Oxygen): This system utilizes bacteria that live without oxygen. It is suitable for waste with very high organic loads (COD/BOD > 3000 mg/L). Its advantage is low energy consumption because it does not require air blowers, and it produces byproducts in the form of biogas that can be utilized as energy. However, the process is slow and can often cause odors if not managed with a good closed system.
Aerobic System (With Oxygen): This is the most common method. We supply oxygen using aerators or blowers into the tank. Aerobic bacteria work very fast in decomposing pollutants and do not cause foul odors. However, the challenge is the electricity cost for oxygen supply.
Often, the best solution is a Hybrid. We use an Anaerobic system at the beginning to drastically reduce the organic shock load, followed by an Aerobic system to polish the wastewater until it is clear and meets quality standards.
2. The Role of Waste Decomposing Bacteria
The success of a biological system depends entirely on the health of the biomass. The waste decomposing bacteria we use are selected cultures that have been acclimatized (adapted) to your specific industrial waste type. During the commissioning phase, our process engineer team will monitor the F/M ratio (Food to Microorganism), DO (Dissolved Oxygen), and MLSS (Mixed Liquor Suspended Solids) to ensure bacteria are working optimally to degrade pollutants. Without proper bacterial management, a WWTP is just a dead pond that doesn’t function.
3. Hero Technology: Membrane Bioreactor (MBR)
As a leader in water treatment technology, PT Mizui Osmosa Teknovasi highly recommends MBR (Membrane Bioreactor) technology for industries with limited land availability but desiring the best results.
MBR is a combination of the activated sludge process (biological) with membrane filtration (physical). In conventional systems, the separation of sludge and clean water is done by gravity sedimentation, which takes up vast space and often allows solids to escape (resulting in turbidity).
With MBR, water is forced through membranes with microscopic pores (ultrafiltration). Bacteria and solids are completely retained, while clean water passes through.
Why is MBR Superior?
Small Footprint: Saves up to 50% of land area because it eliminates the need for large sedimentation tanks.
Superior Effluent Quality: Treated water is crystal clear, free of pathogenic bacteria, and often meets standards for water recycle (can be reused for cooling towers or irrigation).
High Stability: More resistant to fluctuations in waste load.
Here is a comparison between conventional systems and MBR that you need to know:
| Feature | Conventional Activated Sludge | MBR Technology (Mizui Osmosa) |
| Effluent Quality | Good (Depends on sedimentation) | Excellent (Clear & Solid-Free) |
| Land Requirement | Large (Requires many tanks) | Small (Compact) |
| Recycle Potential | Low (Needs extra filters) | High (Ready for RO/Recycle) |
| Sludge Production | High | Low (Less Sludge Handling) |
| Initial Investment | Low – Medium | Medium – High |

WWTP Installation Service Stages at Mizui Osmosa
We understand that building a WWTP is a complex project. As a professional industrial WWTP contractor, we apply structured project management to ensure projects are On Time, On Budget, and On Spec. Here are our work stages:
Site Assessment & Waste Characterization Our team visits your factory to take waste samples and analyze site conditions. We calculate daily flow rates, peak hour fluctuations, and pollutant characteristics. This data is the foundation of the design.
Engineering Design (Process & DED) Based on initial data, we design the Process Flow Diagram (PFD) and Piping and Instrumentation Diagram (P&ID). We also create Detailed Engineering Drawings (DED) for civil and mechanical works. At this stage, we determine whether to use WWTP construction with concrete (civil) or use fabricated tanks (fiberglass/mild steel) for faster deployment.
Civil Construction & Fabrication Our civil team works on building equalization tanks, aeration tanks, and machine rooms. In parallel, our workshop team fabricates control panels, piping systems, and equipment skids. This synergy accelerates project duration.
Mechanical & Electrical Installation (ME) Installation of pumps, blowers, diffusers, mixers, and instrumentation systems (pH sensors, flowmeters). We use industrial-quality components that are corrosion-resistant and have a long lifetime. Electrical installation is carried out with high safety standards.
Seeding & Acclimatization This is the stage of “bringing the WWTP to life.” We introduce bacterial seeds and perform the acclimatization process. We “feed” the bacteria gradually until the biomass grows sufficiently (MLSS achieved) and is stable enough to accept the full waste load.
Commissioning & Training We conduct thorough trials. Treated water is tested in an accredited laboratory to prove compliance with quality standards. Once the system runs perfectly, we perform the handover and provide intensive training to your operators. We will not leave you until your operators understand how to maintain the system.
Cost Analysis: Smart Investment for the Future
The question most frequently asked is, “What is the price of building a WWTP?”
The cost of WWTP installation varies greatly and is influenced by three main factors:
Capacity (m³/day): The larger the waste discharge, the larger the civil dimensions and equipment required.
Pollutant Load (Inlet Quality): Waste with a COD of 500 mg/L is certainly cheaper to treat than waste with a COD of 10,000 mg/L.
Technology & Effluent Quality: MBR systems indeed have a higher initial investment cost (CAPEX) compared to conventional ones, but they offer land savings and potential cost recovery through water recycling.
It is important to understand that Wastewater treatment installation services that are too cheap often hide swelling operational costs (OPEX) in the future. Poor design leads to excessive chemical use, wasteful electricity consumption, frequent pump breakdowns, and environmental fines because the water never clears up.
At Mizui Osmosa, we focus on Total Cost of Ownership. We design systems that might be slightly higher in initial investment, but provide long-term operational savings and peace of mind because you are free from legal risks.
