For solids control fields, it’s very important to know some points about the selection and application of polymer flocculants, here are some advice from GN Separation:

① Selection of species: The action mechanism of flocculants is charge neutralization polymer bridge, so anionic and cationic flocculants should be selected according to the charge characteristics of the separated materials.

② Selection of dosage: The best dosage of flocculant is that the flocculant is completely adsorbed on the surface of the solid phase particles and the flocculation sedimentation speed reaches the maximum. When the flocculant exceeds the optimal amount, the flocculation effect will decrease.

③ Selection of molecular weight: The larger the molecular weight of the flocculant, the stronger the capture power of solid particles, and the better the flocculation effect. If the molecular weight of the flocculant is too small. No flocculation effect will be achieved. For sludge dewatering, the selected molecular weight must be ≥ 3 million.

④ Shear strength of flocculant: Flocculants used in belt filter presses and decanter centrifuges have different shear strength requirements. High for general decanter centrifuges. And in the small sample test, you need to use a stirrer to verify the intensity of different stirring.

⑤ Selection of the feeding position; after flocculant is added, the flocculation settling speed is faster. If it is transported through a long-distance pipeline, it will easily cause pipeline blockage. According to tests, it is best to dissolve the flocculant solution with good solubility. Add at the decanter centrifuge inlet

⑥ Dissolving method of flocculant: High-speed mechanical stirrer cannot be used to dissolve the polymer flocculant, because the strong mechanical stirring will destroy the molecular chain of the flocculant, and the effect of the flocculant will be significantly reduced. Generally, the stirring speed of the dissolving flocculant is less than 50 rpm, and it is appropriate to divide it. The blade of the mixer should be as wide as possible. Studies have shown that the flocculant is 0.4 to 0 after being added to water. 6MPa compressed air bubbling is the best method to dissolve the flocculant-the dissolution is very uniform and the dissolution rate is extremely fast.

News from GN company this week: Recently, 1 set of High Speed Tubular Centrifuge have been manufactured and are ready to start serving for an European Client’s project. The equipment includes: GNGQ142 High Speed Tubular Centrifuge, VFD control panel and accessories.

Tubular Centrifuge is also called Tubular Separator. It is a type of fine separation equipment, which is suitable for suspensions with thin concentration, fine particles, and small density difference solid-liquid separation, or liquid-liquid-solid separation. It is an indispensable equipment for pharmaceutical, food, chemical, biological product, fermentation broth, beverages, blood products and other industries. Its working principle is that materials with different specific gravity are subject to different centrifugal forces when rotating at high speed, so as to achieve the purpose of separation.

To make sure theTubular Centrifuge will provide a reliable performance and the parts and components of all the equipment will run smoothly for a long term operation, our technical department, production department and quality control department have paid a lot of attention to the material selection, material preparation, every step of production and the inspection for this set of equipment in each step.

If you need any support about the operation and maintenance of GN’s Tubular Centrifuge, please feel free to contact GN company for our engineers’ best experience and knowledge in the relevant industry. We will do our best to assist your project because just in this way we can establish a stable and long term cooperation. And we can provide on-line support and site instruction for specific situation if needed.

As a leading manufacturer of separation equipment and conveying equipment, GN always pay high attention to the product quality and consider the long-term benefits for our users. We would also like to introduce GN as a professional manufacturer in decanter centrifuge field, GN pays a lot of attention in the selection of raw materials, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used.
