Salah satu solusi yang saat ini banyak digunakan adalah ACH water treatment, yaitu metode yang menggunakan Aluminum Chlorohydrate (ACH) sebagai coagulant berperforma tinggi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dibandingkan dengan coagulant konvensional, ACH menawarkan kinerja koagulasi yang lebih kuat, produksi sludge yang lebih rendah, serta operasi yang lebih stabil pada berbagai kondisi raw water. Karena keunggulan tersebut, ACH semakin banyak digunakan pada municipal water treatment plant, industrial water system, serta proses wastewater treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Apa Itu ACH?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminum Chlorohydrate (ACH) adalah coagulant berbasis aluminium dengan tingkat basicity tinggi yang umum digunakan dalam proses water treatment. ACH termasuk dalam kelompok pre-polymerized aluminum coagulants, yang berarti sebagian proses hydrolysis sudah terjadi pada saat proses produksi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Karena struktur ini, ACH mengandung konsentrasi polymerized aluminum species yang lebih tinggi, yang sangat efektif untuk mendestabilisasi partikel tersuspensi dalam air.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dari sisi operasional, ACH memiliki beberapa keunggulan dibandingkan coagulant tradisional seperti aluminum sulfate (alum) atau basic aluminum chloride:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kandungan aluminium lebih tinggi sehingga dosis penggunaan lebih rendah<\/li>\n\n\n\n<li>Reaksi koagulasi lebih cepat, meningkatkan efisiensi treatment<\/li>\n\n\n\n<li>Produksi sludge lebih rendah, sehingga biaya pengolahan sludge lebih kecil<\/li>\n\n\n\n<li>Rentang pH efektif lebih luas, sehingga dapat digunakan pada berbagai kondisi raw water<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Karakteristik ini membuat ACH menjadi coagulant yang banyak dipilih pada sistem water treatment modern, terutama ketika konsistensi kualitas air dan efisiensi operasional menjadi prioritas utama.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Baca Juga: <a href=\"https:\/\/www.lautanairindonesia.com\/id\/publication\/inorganic-coagulants\/\" target=\"_blank\" rel=\"noreferrer noopener\">Koagulan Anorganik untuk Pengolahan Air yang Lebih Baik<\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Peran ACH dalam Water Treatment<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Dalam praktik operasional water treatment, peran utama ACH adalah sebagai coagulant yang menghilangkan suspended particles, turbidity, dan natural organic matter dari raw water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Proses ACH water treatment umumnya terjadi pada tahap coagulation dan flocculation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Mendestabilisasi Suspended Particles<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Raw water biasanya mengandung fine particles, colloids, dan organic matter yang tetap tersuspensi karena memiliki muatan permukaan negatif. Muatan ini menyebabkan partikel saling menolak sehingga tidak dapat mengendap secara alami.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ketika ACH ditambahkan ke dalam air:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Polimer aluminium bermuatan positif akan menetralkan muatan partikel<\/li>\n\n\n\n<li>Partikel tersuspensi menjadi tidak stabil<\/li>\n\n\n\n<li>Partikel mulai bertumbukan dan saling menempel<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Tahap ini disebut coagulation, yang menjadi dasar dari proses penghilangan padatan secara efektif.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Membentuk Flocs yang Lebih Besar untuk Mempermudah Pemisahan<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Setelah proses netralisasi muatan terjadi, partikel-partikel yang tidak stabil akan mulai beragregasi membentuk gumpalan yang lebih besar yang disebut flocs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flocs ini memiliki ukuran dan massa yang jauh lebih besar dibandingkan partikel individu sehingga dapat lebih mudah dipisahkan melalui proses seperti:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Clarification atau sedimentation<\/li>\n\n\n\n<li>Dissolved Air Flotation (DAF)<\/li>\n\n\n\n<li>Filtration systems<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">ACH dikenal sangat efektif dalam membentuk flocs yang padat dan kuat, sehingga meningkatkan efisiensi pemisahan dan mengurangi beban pada unit filtrasi di tahap berikutnya.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Meningkatkan Penghilangan Turbidity dan Organic Matter<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Peran penting lainnya dari ACH water treatment adalah membantu menurunkan turbidity dan natural organic matter (NOM) dalam raw water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tingkat turbidity yang tinggi dapat mengganggu proses disinfection dan menurunkan kualitas air secara keseluruhan. Dengan menghilangkan partikel tersuspensi dan senyawa organik secara efektif, penggunaan ACH membantu menghasilkan:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Air yang lebih jernih setelah proses clarification<\/li>\n\n\n\n<li>Kinerja filtration yang lebih baik<\/li>\n\n\n\n<li>Proses disinfection yang lebih efektif pada tahap selanjutnya<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Hal ini sangat penting terutama pada drinking water treatment plant, di mana kontrol turbidity harus konsisten untuk memenuhi standar regulasi kualitas air.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Baca Juga: <a href=\"https:\/\/www.lautanairindonesia.com\/id\/publication\/high-tss-and-turbidity-in-raw-water\/\" target=\"_blank\" rel=\"noreferrer noopener\">Bagaimana Dampak TSS dan Turbidity Tinggi dalam Air Baku?<\/a><\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Mendukung Operasi Plant yang Lebih Stabil<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Salah satu keunggulan operasional utama dari ACH adalah stabilitas proses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Karena ACH memiliki basicity yang tinggi, penggunaannya menyebabkan penurunan pH yang lebih kecil dibandingkan coagulant tradisional seperti alum. Hal ini berarti:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kebutuhan bahan kimia penyesuaian pH lebih rendah<\/li>\n\n\n\n<li>Kondisi proses treatment menjadi lebih stabil<\/li>\n\n\n\n<li>Konsumsi bahan kimia secara keseluruhan lebih rendah<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Bagi operator plant, hal ini berarti kontrol proses yang lebih sederhana dan performa yang lebih konsisten, terutama ketika kualitas raw water mengalami fluktuasi.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Kapan ACH Umumnya Digunakan dalam Water Treatment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ACH water treatment banyak digunakan dalam berbagai aplikasi pengolahan air, antara lain:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Municipal Drinking Water Treatment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Penghilangan turbidity<\/li>\n\n\n\n<li>Pengurangan organic matter<\/li>\n\n\n\n<li>Surface water clarification<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Industrial Water Treatment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Proses penjernihan air<\/li>\n\n\n\n<li>Pretreatment sebelum filtration atau membrane systems<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Wastewater Treatment<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Penghilangan suspended solids<\/li>\n\n\n\n<li>Meningkatkan sludge settling performance<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Karena efisiensi yang tinggi dan performa operasional yang stabil, ACH sering dipilih ketika water treatment plant membutuhkan kinerja yang konsisten dengan penggunaan chemical yang lebih optimal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Baca Juga: <a href=\"https:\/\/www.lautanairindonesia.com\/id\/publication\/improve-the-water-treatment-plant-efficiency\/\" target=\"_blank\" rel=\"noreferrer noopener\">Meningkatkan Efisiensi Water Treatment Plant untuk Operasi yang Berkelanjutan dan Cost-Effective<\/a><\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tingkatkan Performa Water Treatment Anda dengan ACH<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pemilihan coagulant yang tepat merupakan faktor penting untuk mencapai hasil water treatment yang stabil dan efisien.

One of the most reliable solutions widely used today is ACH water treatment, which utilizes Aluminum Chlorohydrate (ACH) as a high-performance coagulant. Compared with conventional coagulants, ACH provides stronger coagulation performance, lower sludge production, and more stable operation across different raw water conditions. Because of these advantages, ACH is increasingly applied in municipal water treatment plants, industrial water systems, and wastewater treatment processes. What is ACH? Aluminum Chlorohydrate (ACH) is a high-basicity aluminum-based coagulant commonly used in water treatment processes. It belongs to the family of pre-polymerized aluminum coagulants, meaning that part of the hydrolysis process has already occurred during manufacturing. Because of this structure, ACH contains a higher concentration of polymerized aluminum species, which are highly effective at destabilizing suspended particles in water. From an operational perspective, ACH offers several advantages compared to traditional coagulants such as aluminum sulfate or basic aluminum chloride: These characteristics make ACH a preferred coagulant in many modern water treatment systems, particularly where consistent water quality and operational efficiency are priorities.

The ACH water treatment process generally occurs in the coagulation and flocculation stages. 1. Destabilizing Suspended Particles Raw water typically contains fine particles, colloids, and organic matter that remain suspended because they carry negative surface charges. These charges prevent the particles from naturally settling. When ACH is added to the water: This step is known as coagulation, and it forms the foundation of effective solid removal. 2. Forming Larger Flocs for Easier Removal After charge neutralization, the destabilized particles begin to aggregate into larger clusters called flocs. These flocs are significantly larger and heavier than individual particles, allowing them to be removed through processes such as: ACH is particularly effective in forming dense and strong flocs, which improve separation efficiency and reduce the load on downstream filtration units. 3. Improving Turbidity and Organic Removal Another important role of ACH water treatment is reducing turbidity and natural organic matter (NOM) in raw water. High turbidity can interfere with disinfection processes and reduce overall water quality. By efficiently removing suspended particles and organic compounds, ACH helps achieve: This is especially important for drinking water treatment plants, where consistent turbidity control is required to meet regulatory standards.

Because ACH has high basicity, it causes less pH depression compared with traditional coagulants like alum. This means: For plant operators, this translates to simpler process control and more predictable performance, particularly when raw water quality fluctuates. When is ACH Commonly Used in Water Treatment? ACH water treatment is widely applied in several water treatment scenarios, including: Municipal Drinking Water Treatment Industrial Water Treatment Wastewater Treatment Because of its high efficiency and operational reliability, ACH is often selected when treatment plants require consistent performance with optimized chemical usage.
