Cara Efektif Menurunkan TDS Air untuk Kualitas Air yang Lebih Baik

TDS (Total Dissolved Solids) adalah jumlah total zat padat terlarut dalam air, seperti mineral, garam, logam berat, dan senyawa organik. Ketika TDS terlalu tinggi, kualitas air menurun—baik dalam hal rasa, kejernihan, maupun keamanan untuk dikonsumsi atau dipakai dalam proses industri.
Oleh karena itu, memahami cara menurunkan TDS air menjadi hal yang sangat penting.

Apa Penyebab TDS Tinggi?

Air dengan TDS tinggi umumnya dipengaruhi oleh:

Kandungan mineral alamiah seperti kalsium, magnesium, dan natrium
Kontaminasi dari industri atau limbah rumah tangga
Sistem perpipaan yang korosif
Garam terlarut pada air tanah atau air payau
Bahan organik dan anorganik terlarut

Menurut laporan dari WHO tentang kualitas air minum, TDS yang tinggi dapat memengaruhi rasa air, efektivitas sabun, dan bahkan tingkat korosi pada peralatan.

Cara Menurunkan TDS Air yang Paling Efektif

Ada beberapa metode yang dapat digunakan untuk menurunkan TDS secara signifikan, bergantung pada kebutuhan rumah tangga, komersial, maupun industri.

1. Reverse Osmosis (RO) — Metode Paling Efektif

Teknologi Reverse Osmosis mampu menurunkan TDS hingga lebih dari 95%, menggunakan membran semipermeabel untuk menyaring zat terlarut.

RO umum digunakan pada:

Air minum rumah tangga
Industri makanan dan minuman
Industri farmasi
Air umpan boiler

Untuk menjaga performa membran RO tetap optimal, penting menggunakan bahan kimia seperti Reverse Osmosis Cleaning Agent agar membran tidak tersumbat oleh scaling dan fouling.

2. Menggunakan Resin Ion Exchange

Metode ini bekerja dengan menukar ion dalam air—misalnya kalsium dan magnesium—dengan ion natrium atau hidrogen.
Paling efektif untuk:

Air industri
Softening (pelunakan air)
Pre-treatment sebelum membran RO

3. Distilasi

Distilasi menguapkan air kemudian mengembunkan uap tersebut, sehingga meninggalkan zat padat terlarut.
Metode ini efektif tetapi memerlukan energi lebih besar.

4. Filtrasi Multi-Stage

Filtrasi berlapis (sand filter, carbon filter, AFM filter) dapat membantu menurunkan beberapa jenis TDS, terutama partikel padat dan organik.

AFM sangat efektif meningkatkan kualitas filtrasi sebelum proses RO. Lihat juga produk internal seperti Liqua-Zen Z468 yang berfungsi meningkatkan performa sistem pengolahan air.

5. Chemical Treatment untuk Menurunkan TDS Air

Penggunaan bahan kimia tertentu dapat menurunkan TDS dengan mengikat mineral dan kontaminan sehingga lebih mudah disaring. Contohnya:

Coagulant
Flocculant
Scale inhibitor

Anda dapat melihat beberapa opsi bahan kimia pendukung sistem water treatment pada laman Chemicals & Filter Media GLS.

Batasan TDS yang Disarankan

Mengacu pada SNI dan WHO, batas TDS air minum yang direkomendasikan adalah:

< 500 mg/L — ideal untuk air minum
500–1000 mg/L — masih dapat diterima, tetapi rasa mungkin berubah
> 1000 mg/L — tidak direkomendasikan

Untuk air boiler atau industri tertentu, batas TDS bahkan harus jauh lebih rendah.

Menurunkan TDS Air Penting untuk Kualitas Hidup & Industri

Menurunkan TDS air adalah langkah krusial untuk meningkatkan kualitas air dan mencegah masalah pada peralatan, proses industri, maupun kesehatan. Teknologi paling efektif tetap Reverse Osmosis, dan performanya dapat ditingkatkan menggunakan chemical treatment seperti yang tersedia di PT. Gapura Liqua Solutions.

Teknologi filtrasi yang tepat memastikan air lebih bersih, aman, dan sesuai standar.

AFM for Microplastic Issue — How Activated Filter Media Solves Modern Water Pollution Challenges

Microplastic pollution has become one of the most concerning environmental challenges in recent years. These tiny plastic fragments, often smaller than 5 millimeters, are now found in rivers, lakes, groundwater, and even rainwater. To address this problem, many industries and water treatment facilities are turning to AFM for microplastic issue as a high-performance filtration solution.

AFM, or Activated Filter Media, is an engineered glass filtration media designed to outperform traditional sand filters, especially when dealing with extremely fine particles like microplastics.

Why the Microplastic Issue Matters

Microplastics enter the water cycle through:

Degradation of plastic waste
Laundry fibers (synthetic textiles)
Tire wear particles
Industrial discharge
Urban runoff

Studies have shown that microplastics are now found even in rainwater and urban air. One widely discussed study from Indonesia highlights microplastics being detected in rainwater samples in Jakarta, raising questions about long-term environmental and health impacts.
(reference source: U.S. EPA discusses microplastic pollution in water systems.)

This situation demands more advanced filtration methods than traditional sedimentation or sand bed media.

What Is AFM and Why It Works for Microplastic Removal?

AFM (Activated Filter Media) is an advanced filtration media made from processed green glass, engineered to deliver:

Better filtration performance
Reduced biofouling
Higher removal of microscopic particles
Chemical-free operation

Compared to traditional sand, AFM has enhanced surface activation that traps smaller particles more efficiently. It can filter down to 5 microns, making it effective at capturing microfibers and microplastic fragments that conventional media would allow to pass through.

You can explore other filtration products such as Liqua-Zen Z468 which are often paired with AFM for optimized system performance.

How AFM Removes Microplastics from Water

1. Enhanced Surface Activation

AFM has a negative surface charge that attracts positively charged microplastic particles, improving adsorption.

2. Superior Filtration Depth

Its uniform particle shape and activated surface create deeper filtration zones, trapping particles as small as 5 microns.

3. Less Biofouling

AFM resists bacterial growth, preventing mudballs and channeling—problems that reduce sand filter performance over time.

4. Self-Sterilizing Properties

AFM contains free radicals that continuously disinfect the media surface, maintaining consistent filtration efficiency.

5. No Chemical Additives Needed

AFM works effectively even without flocculants, though systems using coagulants such as Special Coagulant often achieve even better microplastic removal rates.

Advantages of Using AFM for Microplastic Issue

✔ Removes Microplastics Down to 5 Microns

Ensures cleaner, safer, and more sustainable water.

✔ Long-Term Media Stability

AFM does not degrade like sand and can last indefinitely when properly backwashed.

✔ Reduces Chlorine Demand

Due to its bio-resistant surface, AFM minimizes organic contamination.

✔ Improves Water Clarity

Ideal for drinking water treatment, industrial wastewater, resort filtration, and municipal utilities.

✔ Environmentally Friendly

Made from recycled glass and requires no chemical treatment.

Applications of AFM in Indonesia

Industries across Indonesia are now transitioning to AFM in the following areas:

Drinking water treatment plants
Resort filtration systems
Industrial wastewater treatment
Hotel water filtration
Swimming pool systems
Municipal water utilities

For advanced process stages such as polishing or membrane systems, AFM helps protect downstream technologies like RO units. Learn more in Reverse Osmosis Cleaning Agent.
