Liquid polymer dosing by batch

Liquid polymer dosing by DBL batchAvailable for rent with purchase option!

Dosing equipment for water treatment products, these batch dilution skids are simple to operate and maintain with the following characteristics

  • Equipped with an ultrasonic sensor
  • Made with premium and 100% recyclable materials
  • 316 L stainless steel stirrer
  • HDPE tank structure
  • Has control alarms

The DBL skid has several variations depending on the size of your installation and can be coupled with other 1h2o3 packages, allowing you to create your own customized turnkey process!

Whether it is to make water drinkable or to purify it, the use of dosing products is very common. To make assembly and integration easier for you, 1h2o3 has developed a wide range of skids for the dosing of liquid polymers. These complete skids allow liquid chemicals to be diluted with water in a batch process at varying concentrations.

Operating principle of the DBL

The level of the available solution is controlled by an ultrasonic sensor located outside the tank, which allows :

  • In the lowest level, to restart the preparation of a batch;
  • In high level, stop the dilution water supply and the pumping of the mother solution.

The operation is controlled by the contactor placed on the rotameter

Alarm system

  • Equipment fault: a fault on one of the skid’s equipment
  • Preparation fault: if the high level is not reached after the set time

The batch liquid dosing equipment has the following components:

  • Control cabinet made of Siemens components with synoptic panel and two-colour LED signalling of the main parts.
  • Peristaltic type suction pump with high suction capacity, suitable for standard or viscous liquids, driven by a motor and controlled by a variable speed drive in a ratio of 1 to 10.
  • Stirrerwith removable quick coupling system, shaft and 45º smooth tetrapetal propellers in 316 stainless steel. Two propellers in the two-stage versions.

Complete skid for diluting liquid chemicals with water in a discontinuous way at variable concentrations.

The structure is suitable for chemically compatible liquids that can be dosed with a peristaltic pump, such as polymers. In option, we have :

  • Peristaltic dosing pump: to dose the daughter solution to the process with on/off contact
  • Double stage tank: can be removed if maturation is not required.
  • Safety box: PE safety box for the dosing pump.
  • Accuracy of dosing: precise dosing of a stock solution can often only be done on/off because of the small quantities to be injected. Dosing a daughter solution allows smoothing the injection.
  • Maturation : Many products, such as flocculants, must be dissolved before use to ensure their effectiveness.
  • Savings on stock solution: buying a concentrated product and diluting it is often cheaper than buying the product already diluted.
  • Improved process stability: Due to better dispersion, product consistency and process stability are improved.
  • Reduced losses: In their concentrated commercial form, coagulants and flocculants have long shelf lives, thereby reducing the cost of losses due to degradation.
