Phosphoric Acid Filtration

Acid Water Treatment

Acids such as phosphor, sulfur, nitric, and hydrochloride are essential ingredients in many products, such as fertilizers, chemicals, pharmaceuticals, mineral leaching, petroleum refining, and food and beverage. Yet, these acids are crucial treating to obtain the best acid quality.

Pure acid is liquid with a very low pH. They are essential to obtain superior acid quality to offer the best industrial merchant grade acid (MGA) and meet all regulatory standards and requirements on MGA.

Yet, as they are highly corrosive, they require durable and robust filtration technologies. To obtain the best MGA cost-effectively, LiqTech Water has developed an acid filtration system. The system is robust and can be used for caustic filtration, phosphoric filtration, and much more.

The LiqTech acid treatment system can deliver results that are simply impossible or impractical for conventional filtration technologies to reach. The acidic treatment system provides mechanical separation of unwanted solids and particles to purify the pure acid. It is a reliable solution, ensuring a stable and cost-effective operation that can go on and on. With a durable and dependable system, you do not need to worry about replacement costs.

Phosphoric Acid Filtration

Proven Solution for Phosphoric Acid Filtration

Phosphoric acid (PA) is an essential industrial chemical heavily applied in the fertilizer industry, metallurgical industry, and the food and beverage industry.

The LiqTech Water acid filtration system is ideal for phosphoric filtration. It can be used for phosphate rock (PR), phosphatic fertilizers, phosphate-based food and beverage ingredients, phosphate-based pharmaceutical ingredients, and much more.

Due to the durable ceramic membranes, the system delivers excellent MGA quality. The system can remove > 0.06 µm (60 nm). Additionally, no leaf filter media is needed, allowing you to cut costs on media filters and material costs and resources for changing the filter. Moreover, the system requires close to no maintenance. The membranes are frequently backwashed automatically to avoid membrane fouling. Once backwashed, complete recovery is obtained.

The system provides an unmatched flux and requires the minimum footprint, allowing you to upgrade your capacity to the fullest.

Durable Acid Filtration

The LiqTech acid filtration system can handle even the most aggressive and corrosive fluids in the lowest pH range. Regardless of the condition of the feedwater, excellent permeate quality is reached.

Acid Filtration With Ceramic Membranes

The LiqTech acid treatment system is based on state-of-the-art patented membrane technology. Based on more than 20 years of research and development, we have refined our ceramic membranes enabling our water and wastewater filtration systems to handle even the most aggressive fluids due to a high level of mechanical, thermal, and mechanical stability. The ceramic silicon carbide membranes can withstand liquids in the whole pH spectrum from pH 0-14. This allows the membranes to operate with acids used in fertilizers, pharmaceuticals, food and beverage, metal surface treatment, and many more.

The LiqTech acid filtration system is a low-pressure system requiring low energy. Moreover, it uses no chemicals for operation, only for chemical Cleaning-in-Place (CIP). CIP is performed effectively with significantly reduced water consumption. All these superior attributes allow you to reduce your OPEX significantly and ensures a low cost of ownership.

The acid filtration system is customized to match your specific needs, ensuring the most efficient and durable operation. 

The Sustainable Solution for a Greener Tomorrow

The LiqTech acid filtration system is a clean way to produce merchant-grade acid for various industries. It is a low-energy and chemical-free system.

At LiqTech, we aim to ensure sustainable progress through innovative liquid filtration systems. The LiqTech acid filtration system is driven by low pressure, meaning that it requires low energy.

Additionally, it can operate without chemicals. Chemicals are only needed for chemical Cleaning-in-Place to avoid membrane fouling and maintain superior hygiene standards. It is thus a safe and clean technology, enabling you to take the lead in sustainable change.
