Selection examples
Replacing the distillation unit
The current water treatment equipment in the laboratory includes a distiller with a maximum capacity of 5 liters per hour. The average daily water consumption is 30 liters per hour, resulting in the distiller operating for approximately six hours during a working day, without the capability for night start-up to accumulate a reserve of distilled water.
It was requested to re-equip the laboratory with a system that allows for the accumulation and immediate withdrawal of 10 liters of distilled water at the beginning of the working day, eliminating any waiting time.
The source water quality complies with the requirements of SanPiN 1.2.3685-21, with mineralization not exceeding 200 mg/l and total hardness of 2 meq/l. The optimal solution in this scenario is to install an Aqualab P5 system and an Aqualab HT-24 with a pressurized storage system. This configuration enables the primary treatment unit to be fed directly from the public water supply without the need for additional pre-treatment.
Analog of competitor equipment
The current set of water treatment equipment in a laboratory consists of a distiller and a Milli-Q® IQ 7000 unit designed to produce 18.2 Mohm water.
The Milli-Q® IQ 7000 unit needs to be replaced with a similar unit and keep the distiller as a source of feed water.
The optimal decision in this case would be to install an Aqualab S18+ system. Distillate filling of the built-in tank in both automatic and manual regime is possible. It is recommended to install an Aqualab WD2 distribution system for filtrate collection.
Low water consumption
A laboratory requires equipment with capacity 2 liters of distillate per day. Periodic maintenance of the equipment should be minimal. An additional requirement is no small particles larger than 0.5 microns in the filtrate.
Source water quality meets the requirements of SanPiN 1.2.3685-21, mineralization is no more than 400 mg/l, total hardness – 5 meq/l.
The optimal decision in this case is the installation of an Aqualab TW25 ion-exchange unit and an Aqualab WD1 distribution system. The ion-exchange unit is fed from the city water supply, and the only maintenance is the periodic replacement of the cartridges. Small particles are removed by a 0,22 μm microfilter, which is a part of the distribution system.
Challenging replacement
The current set of equipment for water treatment in a production pharmacy consists of several distillers (total daily output is 150-160 liters). Distillers consume a large amount of electricity, and there is a frequent failure of heating elements due to poor quality source water.
The system needs re-equipment to obtain water for injection without losing capacity. The maximum water consumption is 60 liters within an hour. The source water quality does not meet SanPiN 1.2.3685-21 standards due to total hardness of 8.5 meq/l and mineralization of 800 mg/l. Old steel pipes have led to high iron content in the tap water. The optimal solution is to install a pre-treatment system with an Aqualab PTS-6 unit and Aquaton SFS 835 MINI softener to purify the feed water to required standards.
Due to the high mineralization level of the source water, a two-stage demineralization process is recommended. The first stage involves using an Aqualab AL-8 HF unit. The second stage of desalination and additional purification to achieve injection water quality is conducted with an Aqualab AL-4 UF unit. Additionally, an Aqualab ST-35 Simple+ should be installed between the stages as a buffer storage, and an Aqualab ST-80 Standard+ at the end for storing water ready for distribution.
Feeding washers and sterilizers
The sterilization department requires Type 2 water (1 μS/cm) for the washer. The recommended purified water flow is at least 5 l/min to prevent machine failures. Daily consumption is 150 liters. Source water meets SanPiN 1.2.3685-21 standards, with mineralization no more than 300 mg/l and total hardness of 3.5 meq/l.
The best choice for this case is the Aqualab AL-4 Mobil system. It combines all purification stages in one unit, and its built-in pressurized storage allows a flow rate of up to 6 l/min for the product.
10 Mohm water for analyzers
A biochemical analyzer requires water with a resistivity of 10 megohms*cm. The daily consumption is 50 liters. Also, the feed water should be free of microorganisms and particles larger than 0.2 μm.
Source water quality meets the requirements of SanPiN 1.2.3685-21 (mineralization is no more than 300 mg/l, hardness is 1.5 meq/l), but after downtime of water supply networks (for example during weekend) in the building where the laboratory is located, there is a short-term drop of feed water quality, including rust discharge.
The optimal solution is to install an Aqualab PC24 pre-treatment unit, an Aqualab P10 unit for water type 2 quality, and an Aqualab FP25 ion-exchange unit. This setup ensures a sustained filtrate quality with 10 Mohm*cm resistivity.
Additionally, a storage system with a UV disinfection module (Aqualab ST-35 Standard++) is required together with a 0.22 µm sterilizing microfilter at the consumption point.
