Reverse osmosis and tertiary water treatment have become essential processes in modern industrial and municipal water treatment systems. As global demand for clean and safe water increases, treatment facilities must adopt more efficient methods to remove dissolved salts, heavy metals, suspended solids, and emerging contaminants. Tertiary water treatment represents one of the most advanced stages of wastewater purification, producing high-quality treated water that can meet stringent discharge regulations or be reused for industrial applications.
For many facilities, enhanced clarification technologies play a crucial role in preparing water for tertiary polishing. Equipment such as Dissolved Air Flotation (DAF) systems and Lamella clarifiers have become widely adopted for improving water quality before advanced filtration and membrane processes, including reverse osmosis systems. As a manufacturer of these wastewater treatment solutions, Yosun provides reliable and high-performance equipment that supports efficient, cost-effective, and environmentally responsible water treatment operations.
Reverse osmosis (RO) is a membrane-based process that uses pressure to force water through a semi-permeable membrane, effectively separating clean water from dissolved salts, suspended solids, and many types of contaminants. During this process, pressure forces water molecules across the membrane while retaining contaminants on the concentrated side. RO is particularly effective in removing heavy metals, dissolved ions, organic pollutants, and pathogens, creating high-quality purified water suitable for industrial reuse or further treatment.
Reverse osmosis water production involves several treatment processes to maximize membrane efficiency and lifespan. Because RO membranes can be easily affected by suspended solids or biological fouling, tertiary water treatment systems often integrate advanced clarification and filtration stages before the water reaches the membrane modules. This ensures that the water flowed into the RO units has been pre-treated to minimize scaling, fouling, and unnecessary operating costs.
Tertiary water treatment is the final polishing stage of a wastewater treatment process. While primary and secondary treatment remove much of the organic load and large solids, tertiary treatment removes the finer contaminants that typically remain after these earlier stages. These include dissolved salts, nutrients, fine suspended solids, pathogens, and any remaining trace contaminants that must be removed to meet discharge requirements or facilitate water reuse.
Tertiary treatment often includes one or more of the following processes:
Advanced clarification
Filtration and membrane systems
Reverse osmosis
Nutrient removal
Disinfection
Each of these treatment processes contributes to improving water quality until the treated water meets high-purity standards. Reverse osmosis, in particular, is used when the goal is to create water with extremely low levels of dissolved contaminants.
To maximize the performance of tertiary treatment and reverse osmosis systems, the quality of pre-treated water is crucial. This is where Yosun’s Lamella clarifiers and Dissolved Air Flotation (DAF) systems provide significant value.
A Lamella clarifier enhances the sedimentation process using inclined plates, creating a large effective surface area that allows suspended solids to settle rapidly. This design significantly reduces the footprint of the settling system while improving suspended solids removal efficiency. In tertiary water treatment, Lamella clarifiers are commonly used to reduce turbidity and remove remaining solids left after biological treatment.
By lowering the suspended solids content before filtration or membrane treatment, Lamella clarifiers help:
Improve RO membrane lifespan
Reduce operational cost
Minimize clogging and maintenance
Enhance water quality consistency
DAF systems remove fine suspended solids, micro-flocs, oils, and greases by dissolving air into the water and releasing it as microbubbles. These bubbles attach to solids and bring them to the surface for removal. Yosun’s DAF systems are widely used in industrial wastewater treatment where conventional sedimentation cannot efficiently remove light or slow-settling particles.
In tertiary treatment applications, DAF assists by:
Reducing suspended solids and colloidal particles
Removing low-density contaminants
Enhancing downstream filtration performance
Increasing the effectiveness of disinfection and RO
When combined, Lamella clarifiers and DAF systems prepare wastewater for the advanced processes required in tertiary water treatment, ensuring that the reverse osmosis system receives water with minimal fouling potential.
Integrating reverse osmosis into a tertiary treatment process delivers several performance and environmental benefits:
Reverse osmosis systems remove dissolved salts, trace pollutants, and contaminants that remain after traditional secondary and tertiary treatment stages. This results in high-quality treated water suitable for industrial reuse, cooling tower water, or even potable reuse programs.
Industries facing strict discharge limits for dissolved solids, nutrients, or heavy metals can rely on reverse osmosis as an effective final treatment step. RO can remove contaminants that other treatment processes cannot achieve alone.
When complemented with Lamella clarifiers and DAF systems, reverse osmosis requires:
less energy consumption
fewer membrane replacements
reduced downtime
smoother operation
These improvements translate directly into cost savings and operational reliability.
As industries seek to reduce freshwater consumption, reverse osmosis enables the recovery of high-purity water from treated wastewater. This supports sustainable water management and reduces environmental impact.
Reverse osmosis membranes are highly sensitive to contamination. Even small amounts of suspended solids or organic matter can cause rapid fouling, increasing pressure requirements and reducing permeate quality. Using equipment such as DAF and Lamella clarifiers ensures:
Lower turbidity and reduced suspended solids
Effective removal of colloids and oils
Reduced loading on filtration units
More consistent feedwater quality
Longer membrane life and stable system performance
These systems are essential for any facility aiming to implement tertiary water treatment and reverse osmosis efficiently and sustainably.
Reverse osmosis and tertiary water treatment play a vital role in producing high-quality treated water, supporting industrial reuse, and protecting the environment. By integrating Yosun’s Dissolved Air Flotation (DAF) systems and Lamella clarifiers into the treatment process, facilities can significantly improve water clarity, remove fine solids, and reduce fouling risks before advanced filtration and membrane systems. This strategic combination enhances water treatment performance, reduces operational costs, and ensures compliance with the world’s strictest water quality standards.
