For stakeholders in the hospitality industry, saline well water is a frequent and critical issue. PT Mizui Osmosa Teknovisa is here to provide the precise solution. We offer Brackish Water RO installation services in Lombok and surrounding areas. This technology guarantees a high-quality water supply for your guests’ comfort.
The Mandalika Special Economic Zone (SEZ) in Central Lombok has become a global tourism magnet. The growth of hotels, resorts, and restaurants in this region is skyrocketing. However, behind this grandeur lies a crucial infrastructure challenge: clean water availability.
Poor water quality impacts more than just health. Furthermore, saline water can permanently damage your property assets. This article will dissect how Brackish Water Reverse Osmosis (BWRO) technology serves as the most profitable investment.
Mandalika and surrounding areas, such as Kuta and Tanjung Aan, face unique hydrogeological challenges. Massive groundwater extraction often exceeds the freshwater aquifer recharge rate. Consequently, serious seawater intrusion is unavoidable.
Declining groundwater pressure causes seawater to seep inland. The result is well water turning brackish. Technically, this water has Total Dissolved Solids (TDS) between 1,000 and 10,000 ppm. In contrast, viable drinking water standards must be below 500 ppm.
Beyond salinity, Lombok’s soil structure is rich in limestone. This makes the water hard (high calcium content). The combination of brackish and hard water is a nightmare for hotel operations. This is where the vital role of Lombok brackish water RO machines comes in to resolve both issues simultaneously.
Using raw well water without treatment brings serious consequences. Here are the two main impacts:
Asset Damage (Corrosion & Scaling): Saline water is highly corrosive. Stainless steel pipes and kitchen equipment will rust significantly faster. Additionally, lime content causes scaling in water heaters. Consequently, building maintenance costs will soar drastically.
Decline in Guest Comfort: Water is a guest’s first contact with your facilities. Sticky bathwater or salty coffee will ruin the guest experience. These complaints can trigger negative reviews on social media.
Standard sand filters cannot remove salinity because salt molecule sizes are microscopic. Therefore, the only solution is utilizing Reverse Osmosis (RO) technology.
Natural osmosis moves fresh water into salt water. However, in a BWRO system, we reverse this process. We use high-pressure pumps to push raw water through a semi-permeable membrane.
This pressure forces pure water molecules through, while salt is retained. The water that passes through is called Permeate (clean water), while the dirty water is discharged as Concentrate. Our Lombok brackish water RO systems are specifically designed to handle these extreme coastal conditions.
The heart of our system is the Thin-Film Composite (TFC) membrane element. Its pores are ultra-fine, at 0.0001 microns. This size is far smaller than bacteria or viruses.
Our system boasts a rejection rate of 95% to 99%. This means if your well water has a TDS of 4,000 ppm, our machine can lower it to below 200 ppm. The result is fresh water that meets Health Ministry standards (Permenkes).
Many RO systems fail not due to poor membranes, but due to incorrect pre-treatment. Lombok’s water is very hard. If it enters the membrane directly, the lime will form hard scale stones.
To prevent this, we implement a specific strategy:
Water Softener: Uses resin to capture calcium & magnesium ions.
Antiscalant Injection: Uses food-grade chemicals to prevent minerals from crystallizing inside the membrane.
The Lombok brackish water RO machine system we offer includes a complete sequence before entering the main unit:
Multimedia Filter: Filters mud and sand.
Carbon Filter: Removes odors and chlorine that can damage the membrane.
Micron Filter: Final filtration for fine particles (1-5 microns).
This sequence ensures your membrane lasts up to 3-5 years.
Investing in a BWRO machine is often considered expensive upfront. However, let’s calculate the savings compared to purchasing tank water. Let’s assume your hotel needs 20,000 liters (20 m³) of water per day.
Buying Tank Water: At IDR 60,000/m³, your monthly cost reaches IDR 36,000,000.
Self-Production (BWRO): Electricity and chemical costs are only around IDR 7,000/m³. The monthly cost is only IDR 4,200,000.
You can save approximately IDR 31.8 Million per month. Thus, the capital investment will break even (BEP) in less than 18 months. Afterward, these savings become pure profit for your business.
PT Mizui Osmosa Teknovisa does not just “sell and forget.” We provide comprehensive maintenance services in the Lombok area. Our team is ready to perform routine monitoring, filter replacements, and membrane cleaning (Cleaning in Place/CIP).
Do not let water quality hinder your business. As experts in Lombok brackish water RO machines, we are ready to assist you.
