Henan Secco recently had the pleasure of welcoming distinguished guests from Ukraine—our partners in the water treatment industry. As a professional manufacturer of water treatment chemicals, including Polyacrylamide (PAM) and Poly Aluminium Chloride (PAC), Secco opened its doors to provide a comprehensive view of our operations, from R&D to production.

Polyaluminium Chloride (PAC) is a new type of water purification material and inorganic polymer coagulant, abbreviated as polyaluminum. It is a water-soluble inorganic polymer that lies between AlCl3 and Al(OH)3.

Proper dissolution of Polyacrylamide (PAM) is critical for achieving its optimal performance as a flocculant. Incorrect practices lead to clumping ("fish eyes"), gel formation, and molecular degradation, rendering it ineffective.

Summary Overview In simple terms, PAC and PAM are a classic “dynamic duo” in wastewater treatment, typically used together in the coagulation and flocculation process. PAC acts as a Coagulant. Its main role is to neutralize charges and destabilize tiny suspended particles and colloids, causing them to form micro-flocs. PAM acts as a Flocculant. Its main role is adsorption and bridging, which pulls the micro-flocs created by PAC together into large, dense, and fast-settling flocs. Their relationship can be analogized as: PAC is the “glue” that binds sand into small clumps, and PAM is the “net” that gathers the clumps into a large, easy-to-remove boulder. 1. Polyaluminum Chloride (PAC) 1.1. Mechanism of Action PAC is an inorganic polymer coagulant. Its coagulation mechanism is based on three key principles: Charge Neutralization: Upon dissolving in water, PAC hydrolyzes to produce a multitude of positively charged complex ions (e.g., [Al(OH)₂]⁺, [Al₈(OH)₂₀]⁴⁺). Most colloidal particles in wastewater (e.g., clay, organic colloids) carry a negative surface charge. These like charges cause the particles to repel each other and remain stable in suspension. The positive ions from PAC effectively neutralize these negative charges, compressing the electrical double layer and causing destabilization. This allows the particles to collide...

As the spooky and magical season of Halloween approaches, I would like to extend warmest greetings to you and your team from everyone at Henan SECCO Environmental Protection Technology Co., Ltd. 

The PAM molecule chain contains a large number of charges (usually anionic PAM is used for this purpose), and it can "bridge" to bind the fine, dispersed clay and fine particles in the soil into larger agglomerated structures.

As a trusted supplier of water treatment chemicals, we provide targeted solutions using ‌Polyaluminium Chloride (PAC)and ‌ Polyacrylamide (PAM)to address these challenges efficiently.

As we return from the Mid-Autumn Festival & National Day holidays, our focus is on providing high-quality Polyacrylamide (PAM), Polyaluminium Chloride (PAC), coagulants, and flocculants for your water treatment needs.

Selecting the correct type of Polyacrylamide (PAM) is crucial for efficient and cost-effective treatment of ceramic wastewater. The primary goal is to rapidly remove suspended solids (SS) through coagulation and flocculation.

Let's delve into the selection and application of polyacrylamide (PAM) in plate-and-frame filter presses. This is a very crucial and practical issue. Correct selection and application can significantly enhance the efficiency of the filter press and the final moisture content of the sludge cake.
