Precipitants and flocculants - Import export

The motorised diaphragm dosing pump MEMDOS LA sets new standards with its robust and sophisticated drive concept as well as its ease of operation. The MEMDOS LA series is available in two sizes and covers a wide performance range from 4 to 1020 litres per hour. Thanks to the robust tappet drive and the option of manual or automatic capacity adjustment via external current signals, the MEMDOS LA reliably and precisely doses various media such as acids, alkalis, precipitants and flocculants. This pump is ideal for applications where high precision and reliability are required. The MEMDOS LA offers a flexible and powerful solution for a wide range of dosing requirements and is characterised by its durability and ease of use.

The MEMDOS LP motor-driven diaphragm dosing pump is the ideal choice for applications where the pump needs to be integrated into control systems or control loops. A version with an Ethernet-based MODBUS interface is available specifically for integration into sophisticated automation networks, enabling seamless communication and control. Equipped with a robust plunger drive and the option of manual or automatic capacity adjustment, the MEMDOS LP reliably and precisely doses various media such as acids, alkalis, precipitants and flocculants. This flexibility and precision make it a reliable component in various industrial processes. The MEMDOS LP is also available with a double diaphragm system on request, which ensures increased safety and reliability.

The MEMDOS LB solenoid-driven diaphragm dosing pump is the ideal solution for applications where the pump needs to be integrated into control systems or control loops. Thanks to its robust plunger drive and the option of manual or automatic capacity adjustment, the MEMDOS LB reliably and precisely doses various media such as acids, alkalis, precipitants and flocculants. The dosing capacity is adjusted either by mechanically adjusting the stroke length or by controlling the speed of the three-phase motor via a separate frequency converter. This flexibility enables precise control of the flow rate to meet different requirements. On request, the MEMDOS LB is also available with a double diaphragm system, which offers additional safety and reliability. This combination of versatile control and robust design makes the MEMDOS LB the ideal choice for demanding dosing tasks.

In the treatment of drinking water, whether done conventionally or via seawater desalination, agitators are used for rapid mix, precipitation and flocculation processes. Precipitation and flocculation processes require low shear, slow-running agitators. For pH adjustments and rapid mixing faster running agitators that can blend reactor content in a flash are required. Wastewater treatment also requires a multitude of application options for agitators. In anaerobic and anoxic tanks for nitrogen removal, slow-running agitators are used to suspend and homogenize activated sludge flocs. In aeration tanks, mixer/aerators can be used for efficient oxygenation and mixing. Where waste water is purified, sludge is generated. This sludge is generally conditioned using polymers, dewatered, and then digested in anaerobic sludge digesters to generate biogas. Special agitators are required for both polymer introduction and for digested sludge mixing.
